Obey our summons; from their deepest dells

The Dryads come, and throw their garlands wild

And odorous branches at our feet; the Nymphs

That press with nimble step the mountain-thyme

And purple heath-flower come not empty-handed,

3ut scatter round ten thousand forms minute

Of velvet moss or lichen, torn from rock

Or rifted oak or cavern deep: the Naiads too

Quit their loved native stream, from whose smooth face

They crop the lily, and each sedge and rush

That drinks the rippling tide: the frozen poles,

Where peril waits the bold adventurer’s tread,

The burning sands of Borneo and Cayenne,

All, all to us unlock their secret stores

And pay their cheerful tribute.

2 Mr. A. S. Woodward on some

tions of Quenstedt*, Zittelt, and others, the osteology of

these fishes is still very incompletely known; and a much

fuller knowledge is required before the problem of their

relationships can be solved. One disadvantage under which

nearly all authors hitherto have laboured is the crushed

nature of the specimens. With perhaps only two exceptionsf,

all the important Pycnodont remains as yet described are

flattened in the hard matrix of such formations as the Litho-

graphic Stone of Bavaria and France, the English Purbeck

Stone, and the fissile Cretaceous limestone of Mount Lebanon.

Such specimens are admirable as displaying the trunk and

fins, but rarely of much service in the matter of cranial

osteology; and this must be thoroughly understood before

there can be further progress in classification.

A new departure can now be made by the fortunate dis-

covery of some beautiful skulls and other remains in the soft

clay of Oxfordian age in the neighbourhood of Peterborough.

Thanks to the skill and care of Mr. Alfred N. Leeds, F.G.S8.,

who has already unearthed so many new Jurassic Vertebrata

in this formation and locality, no less than five important

specimens of the Pycnodont genus Mesturus are available for

study. Though partly in concretionary clay, they are nearly

all free from matrix, and can thus be examined almost as

readily as the bones of a recent fish ; the only difficulty con-

sists in imperfections and fractures due to the circumstances

of preservation. Except one specimen, which has been ac-

quired by the British Museum, these fossils are in the private

collection of Mr. Leeds, and will be referred to under their

catalogue-numbers as follows :—

J. DESCRIPTION OF SPECIMENS.

Cranium.

The bones of the cranial roof form a continuous shield,

much arched from side to side, and extend from the occiput

to the rostrum without any fontanelle or loss of the tubercular

ornamentation. The sutures between them can be readily

recognized on close inspection, and the limits of some of the

elements are remarkably inconstant. It is clear, indeed, that

these are merely dermal bones, and there is so much difference

between the cranial roof of the two best-preserved specimens,

that it is necessary to describe them separately.

Specimen no. 1 *.—'The hinder half of the skull in this fossil

(Pl. I.) appears to exhibit its natural form; but from the

middle of the orbits forwards it is much fractured and laterally

compressed. The occipital crest is not much elevated, and

the longitudinal median ridge of the roof is gently rather than

sharply bent from side to side. A few fixed points can be

definitely recognized, and it is necessary in the description to

begin with these for the approximate determination of the

more problematical bones. ‘The occipital border of the cranium

is exposed behind by the crushing of the numerous small

supratemporal scales (Pl. I. figs. 1, 1a, s.t.), and appears to

have been directly transverse, with the exception of a short

median peak formed by the supraoccipital element (s.occ.).

The outer margin of the cranial roof is also well preserved on

each side, and the exact limits both of the otic region and the

orbits (orb.) are indicated. ‘The margin of the supraoccipital

plate (s.occ.) is distinct except in the hindermost part of its

lateral sutures; it projects posteriorly to fit in a triangular

notch of the median supratemporal, and is itself excavated in

front for the reception of the pointed, hinder extremity of

another median plate (p.eth.), which partly separates the

frontals. ‘The latter elements are also readily recognized (fr),

and meet in the middle line anteriorly for nearly one quarter

of their extreme length. Hach frontal in this specimen is

much crushed and fractured; but the sutures can be observed,

and a detached fragment from another specimen (Brit. Mus.

no. P. 6834) confirms the curious bifurcation of the hinder

4 Mr. A. S. Woodward on some

portion here indicated. The outer margin of the bone is

excavated by the orbit (07d.), and exhibits a short and broad

rounded process, extending downwards over the cheek near

its anterior end, apparently covering the lateral ethmoidal

(prefrontal) cartilage ; posteriorly it first meets the squamosal

(sq.), which also enters the border of the orbit, and then it is

excavated by a deep re-entering angle, which divides it into

an outer small, and inner large, posteriorly directed process ;

inwardly it is separated from its fellow of the opposite side by

the supraoccipital (s.occ.) and another median element (p.eth.)

behind, by the ordinary ethmoidal plates (eth.) in front, and

only meets between these for the short length already

mentioned ; anteriorly the margin is not directly transverse,

but inclined much forwards as it approaches the outer edge of

the skull. The squamosal (sq.) is the last readily determin-

able element of the cranial roof, and in connexion with the

specimen now being described it is interesting also to notice

the detached examples of the same bone in the British

Museum fossil no. P. 6834. Nearly one third of the outer

margin of this bone enters the rim of the orbit, its hinder two

thirds forming an almost straight edge above the opercular

region ; the posterior margin is at right angles to the latter,

and the bone unites with adjoining elements in a very wavy

suture. Jt is much broader behind than in front ; and imme-

diately behind the orbital rim there is a rugose facette on its

inferior face for the articulation of the sphenotic (postfrontal).

The smooth hyomandibular facette, which is not much ex-

tended, can also be observed; but the remainder of the

attached surface of the bone exhibits no facettes. Of the

problematical roof-bones, those between the frontal, squamosal,

and supraoccipital (marked # in Pl. I. fig. 1 @) are the most

difficult to understand. On the right side of the fossil, fitting

into the posterior re-entering angle of the frontal, there is an

irregularly triangular plate not extending so far as the

occiput, and this element is apparently subdivided by a

coalesced suture which obliquely crosses its middle. Another

plate, not clearly exhibiting even coalesced sutures, completes

the filling of the space between the last-described plate, the

squamosal, frontal, and supraoccipital. On the left side of

the fossil the same area is occupied by more numerous plates.

One apparently equals the foremost triangular bone, but does

not exhibit any trace of former subdivision. At least four

elements correspond with the hinder bone, the two longitudinal

sutures shown in Pl. I. fig. la being open and the short

transverse suture near the back apparently closed. The

median plate (p.eth.) interposed between the posterior portion

of the frontals and filling the re-entering angle in the anterior

margin of the supraoccipital is bilaterally symmetrical,

acutely pointed behind, and widest in front. Some of its

median tuberculations are relatively very small. The eth-

moidal and facial region in advance of the frontals is appa-

rently completely covered with irregular polygonal plates

(eth.), more finely tuberculated than the hinder portion of the

eranial roof. Some of the posterior median ethmoidal plates

are fused together, but indications of the original sutures are

distinct. The vomerine region (v.), as usual in Pycnodonts,

is shown to be very robust and provided with a regularly

arranged pavement of teeth. Remains of an external tuber-

culated plate on the right side may perhaps represent the

maxilla (Pl. I. fig. 1, y). The stout smooth premaxille

(pmzx.), each exhibiting the bases of three large teeth, are

preserved at the end of the snout.

Specimen no. 24 (Leeds Catalogue)—The second well-

preserved specimen (Pl. II.) wants the ethmoidal region, but

displays the greater part of the cranial roof behind, especially

on the right side. ‘lhe supraoccipital plate (s.occ.) extends,

as described before, in a short pointed process fitting into the

large median supratemporal; but it differs in being much

further produced forwards, and may, indeed, be regarded as

the supraoccipital proper fused completely with the proble-

matical median plate (p.eth.), which is a separate element in

the above-described fossil. The frontals (fr.) are apparently

similar in general form and proportions to those already

described; but there is a marked difference in the circum-

stance that they do not meet at any point in the middle line.

The supposed compound supraoccipital plate gradually con-

tracts in width in its anterior half; but is prevented by

truncation from ending quite in a point. Its contracting

lateral margins articulate with the frontals; but its short

front border is apposed to another median plate (eth.), which

extends as far forwards as the ethmoidal tessere. This

element is algo antero-posteriorly elongated, but gradually

widens to the foremost point of its suture with the frontals,

and is then quickly narrowed again at its irregular articula-

tion in front. It is doubtless equivalent to the triangular

portion of the ethmoidal shield, which only extends into the

frontal region for a very short distance in specimen no. 1.

The outlines of two of the polygonal ethmoidal plates can be

distinguished on the right side of the fossil immediately in

advance of the frontal Among inner bones the crushed

ossified mesethmoid can be seen supporting the single denti-

gerous vomer, while a portion of the parasphenoid splint is

6 Mr. A. S. Woodward on some

exposed from its inferior aspect. The main part of this bone

(fig. 1 a) is short, stout, and broad, produced below into a

median longitudinal keel, and its basipterygoid processes

(dpt.) are short, with a very coarsely dentated articular end.

At the front extremity of the otic region the parasphenoid is

abruptly truncated, the keel terminates in a roughened

pointed knob (&.), and the element continues merely as a

narrow slender median bar across the region of the orbit. A

detached example of the same bone in specimen no. P. 6834

(Pl. III. figs. 8, 3a) may be described in almost similar

terms ; but here the basipterygoid processes (dpt.) are turned

a little more outwards and the median keel is partly broken

away. The inner face (fig. 3a) shows that this keel was

hollow in its deepest portion; and there is a long median

scar for articulation probably with the most anterior elements

of the brain-case. A pair of foramina, one on either side of

the posterior part of the median keel, seem to pierce the bone

and open directly on its inner face.

Other Specimens.—The three more fragmentary specimens

only remain for consideration, and may be dismissed with

brief remarks. No. 2 (Leeds Catal.) is interesting as exhi-

biting the squamosals with the clearly defined straight occipital

border of the skull; and in this fossil the supraoccipital has

a less prominent hinder peak than is observed in the specimens

described above. No. 23 (Leeds Catal.) is very much crushed

and fractured, but the outline of the left frontal is distinct,

and, if appearances be not deceptive, its connexions are

different from those in both types described above. Here

the frontal seems to meet its fellow of the opposite side for

some distance, and the ethmoidal shield is disposed as in

no. 1; but the hinder part of its inner suture is shaped as in

no. 24, and was thus presumably articulated with a median

plate much resembling the anterior end of the supraoccipital

in the last-named fossil. The third and last specimen is the

small group of isolated bones (Brit. Mus. no. P. 6834) of

which the squamosal and parasphenoid have been incidentally

described above. Among these the right postfrontal (sphe-

notic) is specially worthy of notice as being well preserved.

It is small and meets the squamosal in a triangular rugose

facette ; its smooth outer face is triangular, while its equally

smooth anterior face is gently concave, to form part of the

hinder wall of the orbital cavity ; inwardly it is roughened

for articulation with another otic element ; its posterior aspect

takes part in the facette for the upper end of the hyoman-

dibular; and its lower extremity shows a coarsely inter-

digitating articular surface. A problematical bone from the

Remains of the Pycnodont Fish, Mesturus. (i

base of the skull (PI. III. figs. 4, 4a) is also interesting. It

is bilaterally symmetrical and seems to have been formed in

cartilage; and the only suggestion the present writer can

make is that it represents a basisphenoid immediately behind

the parasphenoid. It is longer than broad, and its presumably

inferior face (fig. 4) exhibits a longitudinal keel which is

partly broken away ; it is narrowest at what appears to be its

hinder extremity, while the lateral margins form sharp edges,

each apparently notched near its anterior end. There is an

oblique roughened articular surface behind, shown on the

lower aspect (fig. 4, p.f.), and another similar surface, sloped

in the opposite way, appears from the inferior aspect in front

(a,f.), this fitting very well upon the parasphenoid if it

happens to have been placed as here supposed. The inner

face of this problematical bone (fig. 4.) is comparatively

flat, exhibiting only a possible articular surface at its narrowed

posterior end. A pair of large foramina pierce the bone

obliquely near its middle, the inferior opening being situated

further forwards than its superior exit.

Jaws and Facial Bones.

The mandibular suspensorium is unknown and the pterygo-

quadrate arcade is exhibited only in one specimen (no. 1).

Like that of Anomeodus Willett, this arcade is in the form

of a delicate toothless plate (Pl. I. fig. 1, ptg.), but it is un-

fortunately only preserved and exposed in its most posterior

portion, where the concavely arched front margin of the ecto-

pterygoid passes into that of the quadrate (qu.). The latter

element is comparatively robust, and it seems to exhibit a

surface of attachment tor the symplectic along nearly the

whole of its hinder margin; at least an apparently articular

surface may be observed in this position on both sides of the

only known specimen. Its articular face for the mandible is

irregularly oval, much deeper than broad, and slightly con-

cave. ‘The premaxille (pmzx.) are robust, deep, and narrow,

meeting in the middle line and each showing the bases of

three teeth. ‘They are smooth and overlapped by the tuber-

culated ethmoidal plates, and each is notched on its outer

lateral margin. Whether or not any facial element can be

identified with the maxilla is uncertain ; but one large tuber-

culated cheek-plate (y), deeper behind than in front, extends

down to the border of the upper jaw. ‘his plate is very

thin and toothless. A small cheek-plate (z) covers the outer

face of the postfrontal bone, and there is evidence of equally

small irregular suborbitals (s.0.).. The mandible is sometimes

8 Mr. A. S. Woodward on some

partly obscured by the crushing of facial bones upon it ; but

the four specimens in the Leeds Collection suffice to exhibit

all its elements. The dentary bone (PI. I. fig. 1,d.; Pl. II.

fig. 4; Pl. III. fig. 2, d.) is comparatively insignificant, thin,

deep, and narrow, meeting its fellow in the middle line and

bearing a row of four large teeth. The greater portion of its

external surface is ornamented with tubercles, and it sends a

postero-inferior process underneath the large angular plate.

The latter plate (PI. II. fig.5; Pl. III. fig. 2, ang.) does not

extend upwards so far as the oral margin, but it completes

the hinder portion of the outer face of the mandibular ramus,

and its hinder ascending portion meets a small coronoid bone

(cor.) in a very wavy suture, which is frequently closed. The

upper portion of the coronoid bone is very thin and quite

smooth, and does not reach the tip of the great coronoid

process of the splenial. Indeed, the splenial element (PI. I.

fig. 1, spl.; Pl. II. fig. 3; Pl. III. fig. 2, spl.) is exposed on

the outer aspect of the entire margin of the mandibular ramus

behind the short oral border of the dentary. It is much the

largest and stoutest bone in the jaw, meeting its fellow of the

opposite side at the symphysis and completely covered to the

base of its coronoid elevation with a pavement of teeth. The

articular bone (PI. I. fig. 1, avt.), on the inner face of the

angular and apparently distinct, is always distorted by

crushing, though considerably ossified.

Dentition.

Teeth are confined to the vomer, splenial, premaxilla, and

dentary. They are all hollow, with a short base firmly anchy-

losed to the supporting bone. Certain displaced and unusually

coloured dental crowns are more suggestive of the existence

of successional teeth than any evidence the present writer

has hitherto observed ; but there is still no conclusive proof

of such displacement of the worn teeth. Of the prehensile

front teeth only one is preserved in the right dentary of no. 24

(Pl. II. fig. 4) ; its base is elevated, while the crown is trans-

versely elongated and chisel-shaped, convex on the outer face,

concave within. Asalready mentioned, each premaxilla bears

three of these teeth, while each dentary has four, all about of

equal size. The oral surface of the vomer (Pl. I. fig. 16;

Pl. Il. fig. 2) is flat and bears three principal longitudinal

series of teeth, one median and a symmetrical pair on the

lateral margins. ‘The lateral teeth are not much inferior in

size to those of the median series, but in the anterior half of

the bone there is an intermediate pair of rows of teeth scarcely

Remains of the Pycnodont Fish, Mesturus. 9

half as large as the others; and as these pass backwards they

become more and more irregular, are supplemented with more

intermediate teeth, the majority still smaller and all very

irregularly arranged. The dentition on the splenial bone

(Pl. I. figs. 1, 1c; Pl. II. fig. 8) extends to its outer margin

as far as the base of the coronoid process. ‘There is one

principal longitudinal series of ovai teeth, about as large as

the median vomerine series, but the long axis of each tooth

oblique. The outermost row of teeth (wanting in the original

of Pl. I.) isnot much inferior in size, and, as in the vomer, the

external end of each tooth is produced into a slight peak for

grasping. Within the principal series one regular row of

round teeth about half as large and an innermost irregular row

of still smaller teeth can be observed. Between the principal

and outermost series the same small teeth, disposed almost

symmetrically with those on the inner side of the principal

series, are also seen; but, except in the anterior third of the

bone, these two rows are supplemented and partly disturbed

by the interposition of other small teeth. All these tritoral

teeth in both jaws are smooth and exhibit a shallow apical

indentation, with a crimped margin, very rarely also with a

slight median tubercle. ‘The shape of the indentation varies

with that of the tooth, and the hinder portion of its crimped

border is not infrequently wanting.

Opercular and Branchiostegal Apparatus.

The opercular apparatus is well displayed, and the oper-

culum and preoperculum can be readily identified. On the

lett side of no. 2 these bones are crushed a little downwards

and the upper end of the hyomandibular is thus partly ex-

posed, showing the short and deep process for the suspension

of the operculum. ‘I'he last-mentioned plate is also preserved

among the isolated bones in Brit. Mus. no. P. 6834 (PI. ILI.

figs. 5, 6). It is comparatively small, deep and narrow, its

truncated upper end twice as broad as the supratemporals

(shown in Pl. I. fig. 1), its straight anterior border placed

vertically at the line of the occiput, and its lower half tapering

to a point. In front it is overlapped, as usual, by the pre-

operculum (p.op.), and there is a large hollowed articular

facette (Pl. LIT. fig. 5 a, 7), well within on its anterior border

near the upper extremity, for its suspension on the hyoman-

dibular process. ‘The preoperculum is the large irregularly

triangular plate always conspicuous in Pycnodont skulls,

and in no. 2 its hinder margin distinctly corresponds with

that of the hyomandibular. On the right side of no. 1

10 Mr. A. S. Woodward on some

(Pl. I. fig. 1, p.op.) it is shattered by fracture in front, but it

is well preserved at the upper end; and in this fossil, as also

in no. 2, there is shown interposed between it and the

squamosal a small apparently nearly square plate (z), which

is tuberculated as usual. The preoperculum thus does not

extend upwards quite so far as the operculum, which seems

to touch the hinder angle of the cranial roof; but its great

expanded inferior portion reaches considerably further down-

wards on the cheek than the tapering lower end of the latter

element. Below the preoperculum in no. 1 there are remains

of two slender plates having the appearance of branchiostegal

rays, the upper of considerable size, the lower very small and

delicate. ‘The first is also seen in nos. 2 and 23, and on the

external face it is always in part tuberculated. The space

between the mandibular rami (PI. III. fig. 2) is completely

covered with very small and delicate polygonal tessellated

plates (é.), marked with a tubercular ornament as coarse as

that of the other bones.

Appendicular Skeleton.

The post-temporal bone and supraclavicle are not recog-

nizable. ‘There is reason to believe that neither of them was

exposed on the tuberculated exterior of the fish, for in no. 1

the expanded upper end of the first dorso-ventral series of

flank-scales is shown to curve forwards and to be directly

overlapped by the small supratemporals. ‘he same arrange-

ment is also suggested by no. 2, where the foremost scales

are displaced and exhibit the comparatively fine tubercles of

their hidden front margin. ‘The clavicle is relatively small,

and this element of the left side is detached in no. 24. Its

exposed portion (Pl. II. fig. 6) is restricted and narrow, orna-

mented with tubercles only on its short inferior limb, while

its long fibrous upper limb is considerably thickened. There

is no laminar expansion of the bone bent inwards at its ante-

rior border. The coraco-scapular attachment is shown on the

inner face (Pl. II. fig. 6 a), but neither coracoid, scapula, nor

basals are preserved, only the unjointed bases of the fin-rays

in one specimen.

The pelvic fins are present, but quite small and insignifi-

cant. ‘The best-preserved example in no. 1 exhibits only tive

rays, which are rather stout and soon become very closely

divided and articulated at a short distance above the base.

Nothing is known of the basal pelvic elements.

Of the median fins only a fragment at the origin of the

caudal is preserved in no. 2. This is identifiable on com-

parison with the corresponding fin in a specimen of Mesturus

verrucosus in the British Museum (no. 87023). The rays at

the anterior border gradually increase in length. The two

foremost rays are practically only elongated ridge-scales, the

right and left halves of each being fused together at the

apex ; the next two rays are also unjointed, but exhibiting

the two halves completely separated; the fifth ray shows

three articulations, two being close together and the third a

long distance further up ; the. succeeding rays are all closely

jointed distally. Between the extremities of the second to

the fifth rays on the anterior border there are four short and

delicate regularly alternating intercalary rays, which may

perhaps be termed fulcra.

Squamation.

The trunk is very incomplete in all the specimens, but

considerable portions of the squamation of the abdominal

region are preserved. ‘The scales (Pl. III. fig. 1) are all

thick and quadrangular, not strengthened within by any

well-defined rib, but deeply imbricating, and united above

and below both by the peg-and-socket articulation and by a

jagged suture. ‘This remarkable suture is most pronounced

on the middle of the flank, reduced to a slight waviness

towards the ventral border of the fish, while in one specimen

(no. 23) it is comparatively feebly marked. ‘The external

face of each scale is ornamented with large and rounded

closely arranged tubercles; but these are wanting towards

the smooth hinder border, which is not denticulated. ‘The

very regular flank-series become less regular towards the

ventral margin, and in no. 1 one series terminates in a wedge-

shaped scale slightly above and in advance of the pelvic fins.

Some of the flank-scales are about twice as deep as broad,

while those of the ventral region are mostly about as broad as

deep. ‘The azygous ventral ridge-scales are very narrow,

ornamented as the others, but having some of the tubercles

pointed and delicately striated; they are destitute of any

inwardly directed process, and merely unite with the adjoining

scales by a jagged suture.

Il. SysteMATIC DETERMINATION.

The generic determination of the fossils thus described is

rendered easy by the nature of the scales. The typical species

ot Mesturus, M. verrucosus*, as represented in the British

* A. Wagner, Abh. k. bay. Akad. Wiss., math.-phys. Cl. vol. ix. p. 388,

pl. iii. fig. 1 (1862).

12 Mr. A. S. Woodward on some

Museum by a fine specimen from the Bavarian Lithographic

Stone (no. 37023), shows that most of the scales in this genus

are united above and below by jagged sutures—a feature, so

far as the present writer is aware, unique among fishes. ‘The

new Oxfordian specimens from Peterborough not only agree

in exhibiting this peculiarity, but also in the general aspect

of all the other parts which can be compared. Although the

caudal fin is wanting in all these fossils, there can therefore

be no doubt that they belong to the fan-shape-tailed Mesturus

rather than to the fork-tailed Gyrodus, which is the only

other genus displaying much resemblance.

With regard to specific characters, it may be remarked

that these are usually sought among Pyecnodonts in the tritoral

dentition. The precise characters of the teeth of MM. verru-

cosus, however, are unknown, and the dentition in three of the

Oxfordian specimens now described is so remarkably similar,

notwithstanding the striking differences in the arrangement of

the bones of the cranial roof and the variation in the tuber-

cular ornament, that it is difficult to form any judgment as to

nomenclature. The specimen of MM. verrucosus, however, in

the British Museum is characterized by an irregular enlarge-

ment of the tubercles along the anterior half of the course of

the “ lateral line,” while many of its scales display radiating

structural lines; and both these features are wanting in the

new fossils from the Oxford Clay. We therefore appear to

be dealing with a new species, of which the dental characters

are described in detail on p. 8, and it may be appropriately

named Mesturus Leedsi, in compliment to its discoverer. ‘The

fossil no. 1 (Leeds Catalogue) must be regarded as the type

specimen, and the others are provisionally associated with

it until complete examples of each of these varieties are

discovered.

III. Conc iusions.

Two most important results are obtained from the new

specimens of Mestwrus now described. The arrangement of

the cranial roof-bones of a Pyecnodont fish is discovered for

the first time, and the true nature of the opercular apparatus

is determined. It is also interesting to observe a partial con-

firmation of the facts in regard to the arrangement of the

jaws, which were revealed two years ago by the study of the

Cretaceous genus Anomeodus *.

* A.S. Woodward, “On the Genus Anoma@odus, with Remarks on

the Structure of the Pycnodont Skull,” Geol. Mag. [3] vol. x. (1895)

p. 487, pl. xvii. fig. 1.

Remains of the Pycnodont Fish, Mesturus. 13

The bony shield of the cranial roof is remarkable for its

close resemblance to the corresponding shield in Actpenser

and certain Siluroids. It is, in fact, the first instance of this

arrangement of plates recorded among fishes which exhibit a

trunk and fin-skeleton on the same biological level as the

Pycnodont type. Moreover, the disposition of the sutures is

evidently as capricious as that in Aczpenser ; for not only do

the parietal plates of no. 1 lack bilateral symmetry, but two

specimens so closely similar in other respects as nos. 1 and 24

differ completely in the arrangement of the median roof-

elements. It is also to be noted that in the allied genera

Mesodon, Microdon, and Gyrodus there is only one parietal

plate on each side, while from this in the two first-mentioned

genera there arises a large posteriorly directed process with

digitate extremity, which extends immediately beneath the

dorsal scales of the trunk. In the Cretaceous Coecodus all

the elements of the cranial roof are fused together. The ex-

ternal bones of the Pycnodont skull are thus of an anomalous

and variable character.

The opercular apparatus is equally remarkable, and only

parallelled among deep-bodied Teleostean fishes in which the

jaws are displaced far forwards (e. g. Lampris and the Gym-

nodonts). ‘The small operculum has hitherto been described

as “ supraclavicle;” but if any evidence of its identity is

required beyond that described above, it is only necessary to

examine a specimen of (ryrodus in the British Museum

(no. 37108), where the element may be seen suspended by

the opercular process of the hyomandibular*. ‘The identifi-

cation of the preoperculum (“ operculum ” of previous authors)

is confirmed by its demonstrated relationships in Anom@odus

Willett’. The two branchiostegal rays and the tesseree of the

gular region have previously been noticed in Gyrodus.

In estimating the taxonomic value of these and the gene-

rally-known characters of Pycnodonts it is necessary to

remember two facts :—Firstly, that Accpenser and its living

allies are proved by paleontology to be the degenerate descen-

dants of ganoid fishes which had the cranial roof-bones

arranged in a normal manner (cf. Chondrosteus) ; secondly,

that the disposition of the opercular apparatus, as also the

firm fixation of the pterygo-palatine arcade, observed in the

Pycnodonts, is likewise met with in more than one group of

the bony fishes—is, in fact, merely a physiological correlation

(1) with the reduction in size of the outlet of the gill-cavity,

(2) with the forward displacement of the mouth, and (3) with

donts may be closely related to other ganoid fishes with

normal skulls, and their nearest allies may exhibit a quite

ordinary opercular and branchiostegal apparatus if the mouth

be less displaced or the dentition less powerful.

Having premised so much, it only remains to emphasize

again the contention of Traquair * that the Pycnodont skele-

ton, considered apart from the head, is completely ‘ Lepid-

osteoid” in character. ‘This emphasis is all the more necessary

since, even in a modern handbook, which is authoritative in

most respects, the exploded errors of thirty years ago are

allowed undue influence, and the “special”’ difference between

Pycnodonts and the Palzozoic Platysomide is said to consist

in “the dentition and arrangement of the jaws” +t. Asa

matter of fact, all the fundamental differences are in the trunk.

In Pycnodonts the tail is atrophied-heterocercal, the rays of

the dorsal and anal fins are supported by a single series of

endoskeletal elements of equal number, and there are no

infraclavicles. ven the most specialized of known Platy-

somide never exhibit the faintest approach to this combination

of characters ; the heterocercal tail and multiple-rayed median

fins are as pronounced in the most specialized as in the most

generalized types. ‘The summit of Platysomid evolution

seems to have been attained by the anomalous Permian genus

Dorypterus. The only known link between the grade of fish

to which Platysomus belongs and the higher grade in which

the Pycnodonts must be placed is the Triassic family of

Catopteride, where the upper caudal lobe is hemiheterocercal,

while the rays of the dorsal and anal fins are nearly as few as

their supports, which are ranged in only one series. Present

knowledge is therefore in favour of the supposition that the

Pycnodonts are a secondary modification of the higher or

“ Lepidosteoid”’? grade, which was first reached through

comparatively generalized types of fishes resembling the

Catopteride.

In fact, making allowance for the morphological changes

necessitated by a reduced branchial outlet and a forwardly

displaced mouth—further, admitting that the anomalous

arrangement of the cranial roof-bones is the result of degene-

ration—there is little to distinguish the Pycnodonts from

Lepidotus, Dapedius, and their allies. It is certainly note-

worthy that Lepidotus itself, which has the most highly

developed tritoral dentition, exhibits very few branchiostegal

rays and no gular plate, while the cheek-plates are very

irregularly subdivided. It is also curious that the allies of

this genus and Dapedius (e. g., Tetragonolepis and Aetheo-

lepis) are the only known “ Lepidosteoids”’ in which the

caudal squamation degenerates behind a definite straight line,

as it does in so many Pycnodonts. On the whole, therefore,

it is reasonable to refer the fishes under discussion to a place

among the “ Lepidosteoids ” corresponding with that occupied

by Acipenser among the ‘ Acipenseroids” and by the

Siluride among ordinary Physostomi.

IV.— On the Coccinellidee of Jupan.

By G. Lewis, F.L.S.

BrerorE Mr. G. R. Crotch left for America in 1872 he

determined the species of Coccinellide I then had from

Japan, and furnished me with a list of the species. The

list was afterwards published in the Ent. Month. Mag. x.

the Coccinellide of Japan. 23

pp. 54-56 (1873) ; but only four of the species indicated as

new were described as such in Crotch’s ‘ Revision of the

Coccinellide,’ a posthumous work printed by the Syndics of

the Cambridge University Press, and published in 1874.

Since 1874 Weise has described five species as new from

Japan, and Harold and myself one each; the present paper

introduces eighteen more, and brings the total number known

to fifty-seven. Twelve of these are either identical or

similar to European species; the others are either known

Oriental species or species of an Oriental type.

The synonymy of the Coccinellide as a family is long and

perplexing, and I do not think it would serve any useful

purpose to repeat any part of it here: students who wish

for an elaborate list of names can easily compile one from

the Munich Catalogue of 1874 and from the pages of the

‘Zoological Record for subsequent years. Coccinella decem-

punctata, L., requires two pages in the Munich Catalogue,

which gives seventy names, but Crotch, in his ‘ Revision,’ is

content to cite nine; as a specialist in the group he deemed

this sufficient. Neither have I noticed varietal names, as

these also are recorded in the works named, and I consider

all such names an unnecessary adjunct ‘to a synonymy

already confusing. Some varietal names have been given

apparently under the assumption that particular species have

certain similar aspects which are repeated in various indi-

viduals over and over again; but in Ptychantis axyridis,

Pall., a curious variety may be found which may not occur

again (the patterns of this insect are almost as diversified as

those of the kaleidoscope), and a name given to such a variety

would be a “specimen” name, and would have no right to a

place in any catalogue. If varietal names are or have been

given to specimens which ultimately prove to be good species,

priority cannot be claimed for the names; they have no

status unattached to known and described species to which the

authors originally assigned them.

EPILACHNA, Chevrolat.

The species of this genus are phytophagous, and as such

differ from the others of this series.

Epilachna niponica, sp. 1

Hemispherica, parum opaca; capite disco nigro-maculato; thorace

L. 73-8} mill.

24 Mr. G. Lewis on

Hemispherical, above reddish brown with a pinkish tinge,

somewhat opaque ; the head clearly and rather densely punc-

tulate, with a discal, rather transverse, black mark; the

thorax with a median somewhat triangular black patch, the

pointed end of which touches the basal edge; on the disk it

widens out transversely, leaving a clear margin behind the

head more or less wide, near the base, in a line with the eye,

are two black spots on either side; the scutellum red or

black, usually red, densely punctulate; the elytra with

shallow punctures and a faint alutaceous sculpture, and more

generally over the whole surface is a fine punctuation, the

twenty-eight spots occupy corresponding positions to those

of a typical EZ. 28-punctato, Linn., but they are larger and

the two behind the scutellum join, the two sutural spots on

the disk also sometimes join, beneath in the epipleural fold

there is a long irregular streak, black; the abdomen, fourth

segment of male is canaliculate in the middle, surface of the

channel usually red, rarely black, body beneath black; the

legs, thighs with an elongate black spot or wholly infuscate.

The apices of the elytra are less widely rounded off than

those of L. 28-maculata, Motsch.

Hemispherica, parum opaca; thorace in medio nigro; scutello

rufo; elytris 28-maculatis ; metasterno infuscato.

L. 64-7 mill.

Hemispherical, somewhat opaque, in colour similar to

E. niponica; the head immaculate, somewhat densely but

very finely punctulate ; the thorax with a transverse black

mark on the disk and a small spot midway between it and

the basal edge ; on either side of the discal mark are two other

spots which sometimes join; the scutellum is usually red,

faintly and finely punctulate; the elytra, surface sculpture

similar to that of 4. niponica, but sometimes fainter, with

twenty-eight spots, the pair behind the scutellum are sepa-

rated by a narrow sutural margin, the other spots agree with

those of #. 28-punctata, Linn. ; epipleural fold usually without

a mark, but sometimes there is a faint infuscate streak ; the

fourth segment of the abdomen in male slightly impressed.

Hab. Yokohama and other places. Common.

Epilachna 28-punctata, Fabricius.

Coceinella 28-punctata, Faby. Syst. Ent. p. 34 (1775).

Crotch labelled some of my specimens from South Japan

“H, 28-punctata, F.,” and they are different to those I found

near Yokohama and other places more in the north, and which

I refer to H#. 28-maculata, Motsch. ‘The differences are

chiefly in size and colour generally and in the form of the

thorax, which in 4 28-maculata is more markedly transverse,

and the shoulders also are wider. Crotch remarks of

E. 28-punctata, F., “ This species varies almost to infinity,

and gradually runs into the common six-spotted type, so that

1 cannot give any structural differences ;”’ but Crotch, so far

as I know, never saw typical specimens of L. 28-maculata

nor any examples from the north.

Hlab. Nagasaki and Konosé. Oshima ( Oberthiir).

Epilachna admirabilis, Crotch.

Epilachna admirabilis, Crot. Revis. Coc. p. 81 (1874).

This species is described by Crotch as being like H. macu-

laris, Muls.; the head is immaculate and clearly punctulate ;

the thorax black, with the anterior angles red, lateral margins

and anterior border also sometimes red; the scutellum black ;

the elytra ten-spotted, scutellar and discal sutural spots are

common to both wing-cases, in the middle of each elytron is

a third spot, the fourth is humeral, fifth on the middle of the

elytra edge, the last is before the apex; all the spots are

large, and in one example in thirteen the sutural-discal and

the two outer spots join (this form agrees with Crotch’s type,

which I have seen) ; the under surface and legs usually pale,

but the abdominal segments are sometimes partly infuscate.

I have not observed any sexual differences in the ventral

segments.

Hab. Hakone, Nikko, and abundant at Shiba, near Tokio ;

China (Crotch).

Anisosticta kobensis, sp. n.

Obiongo-ovata, pallide flava; thorace 6-nigro-punctato; elytris

L. 33-4 mill.

The form and number of the spots agree very closely with

those of A. 19-punctata, Linn., but the general colour is

paler and the spots much larger; the elytral punctuation

larger and much clearer, and the legs more slender. The

outline of the body is narrower.

Crotch says that the specimens from Japan “ seem to afford

a passage to C. 7-punctata, Linn.” My series from Japan

consists of both forms, and I think that C. Bruckiz, Muls.,

is only a varietal name.

punctulate on the thorax and elytra. I have some examples

in the Gorham collection from Mexico (a locality given by

Crotch, Revis. p. 116), in which this punctuation is obsolete.

Coccinella ainu, sp. n.

Nigra, supra convexa, nitida; elytris rufis, 12-nigro-punctatis,

parum dense punctulatis.

L. 5-53 mill.

In colour very similar to C. 11-punctata, Linn., but more

broadly oval, and the elytra have a humeral spot. The head

black, with two yellow spots touching the interior edge of the

eye, punctulate; the thorax, punctuation clearer than that

of the head, anterior angles broadly pale; the pale patches

are sometimes joined by a pale anterior narrow margin; the

elytra, on either side of the scutellum is a pale triangular

spot, and behind it a large black sutural spot common to

both wing-cases; in the dorsal region, but quite clear of

the suture, are four more black spots (sometimes the poste-

rior pair are smaller than the anterior pair), on the lateral

area are three smaller spots on either side, the basal or

humeral spot is nearer to the intermediate spot than the inter-

mediate spot is to the apical one. ‘The surfaces of the elytra

are more distinctly punctulate than in either C. 11-punctata,

L., or C. 7-punctata, L. Beyond the pale thoracic margin

noticed above I have not seen any variation of importance.

L. 4-43 mill.

Oblong-ovate, black, shining ; the head black, with a pale

median spot between the eyes, finely punctulate ; the thorax

punctulate like the head, with a pale lateral band or border

rather broad and of equal width throughout; the scutellum

very small and punctulate ; the elytra also punctulate, each

wing-case with two pale or red spots placed longitudinally in

a line with each other near the centres of the wing-cases ; a

point between the spots would indicate the centre of each

elytron ; the epipleural rim is very narrow, especially near the

humeral angle; the ventral segments are laterally pale or

reddish.

Hab. All the islands and in China. Late in autumn, when

this species assembles for hibernation, it may be seen congre-

gating in countless multitudes. I saw it assemble in Kiu

Kiang in 18638, its vast numbers filling the crevices of the

large pagoda near the river. In 1880 I saw a similar multi-

tude at Nikko lining the shutters of a house. The most

dissimilar looking individuals I found in cop.

Anatis halonis, sp. n.

Breviter ovalis, supra convexa; elytris 16-punctatis; C. ocellate

_ proxime affinis, sed pedibus robustioribus et colore dissimili.

Long. 83-9 mill.

Shortly oval, convex, shining; body beneath black, ventral

segments sometimes laterally pale ; the head with somewhat

acinaciform punctures, black, with a yellow spot on the inner

edge of the eye and a smaller pale spot within the anterior

ocular emargination ; the thorax distinctly and densely punc-

tulate, with the lateral rim best-marked at the base, anteriorly .

the rim is very feeble, pale yellow, with an irregular M-shaped

mark in the middle, and exterior to it on either side before the

posterior angles is an isolated black dot; the scutellum red

or black; the elytra, the spots are similar in position to those

the Coccinellide of Japan. 29

of C. ocellata, L., the scutellar pair are very small and round

and equidistant from the scutellum and the suture, surrounded

by a pale halo-like circle, the other spots correspond with

those of C. ocellata, but are all small, being encroached upon

by the pale margin, so much so, indeed, that in the median

spot before the apex the black dot is obliterated or is very

faint; the legs pale reddish brown, tarsi somewhat robust,

posterior tibial carina almost obsolete.

Knowing how variable C. ocellata is, I should have con-

sidered this a variety of it had I not found the tarsi more

robust and the tibial carina distinctly feeble. I have not,

however, seen a specimen of C. ocellata coloured like the

present insect.

All my specimens (thirty-four in number) of this species

agree in colour ; there are two black spots on the basal edge

of the thorax, and the elytra are immaculate. The anterior

edge of the thorax is very thin and pellucid, and the black

eyes are seen through it and appear like two additional spots.

In some of its varieties this species resembles C. conglobata,

Linn., but as my Japanese specimens differ from those of

Western Europe (being narrower and more variable in

colour), I prefer to use Thunberg’s name. Crotch thought

my specimens belonged to the Linnean species. It is not

easy to find two specimens exactly alike, and in recent years

eight varietal names have been added to the earlier list by |

Sajé, Croissandeau, and Weise. One varietal name of

Mulsant’s which belongs to this form or species has been

placed by Crotch under P. dissecta, Muls.

Ménétries and Mulsant placed this species in Synonycha,

the Coccinellide of Japan. 31

and Crotch, apparently overlooking Solsky’s paper, founded

the genus Avolocaria to receive it. I have examined Hope’s

types of Cocernella hexaspilota in the British Museum and

some other Indian specimens similar in colour; but they

appear so different to the Siberian and Japanese specimens

(to which Hope’s name is not appropriate), that Iam reluctant

to follow authors who consider the names synonymous. I

have two specimens with the elytra entirely black and one

with black elytra and a small red humeral spot. For the

first variety the name of négra has been recently suggested

by a continental author; nigripennis would have been a

better name.

continuously in great multitudes in October on telegraph-posts

Chilocorus rubidus, Hope, Gray, Zool. Misc. p. 31 (18381).

In my former list this species stood as C. tristis, a varietal

wholly reddish brown, others are black with a well-defined

discal red blotch on each elytron; Crotch noticed this pecu-

larity.

Rossi’s name, and employed Scriba’s name of C. renipustu-

latus, which is two years later. Crotch says (Revis. p. 185)

that the Japanese ‘ specimens are exactly like C. bivulnerus,

Muls., in the round punctiform dot exhibiting no trace of

any transverse tendency.”

Hemispherical, shining ; the head, body beneath, and legs

brownish red; the thorax and elytra black, the latter not

thickly punctulate on the disk, but distinctly and rather

rugosely punctured laterally. Crotch considered this species

belonged to C. nigritus, Fabr., and recorded it as such

(Revis. p. 184); but it does not agree with any Indian

specimen I have seen in the punctuation of the elytra, and it

also differs in having the scutellum more than as large again.

The anterior tibia are angulate on the outer edge near the

base.

This species is much smaller than S. punctata, Crotch, and

the punctuation is much finer on the thorax; the head red;

the thorax black, with the anterior angles obscurely red; the

elytra red, with a discal black spot common to both wing-

ceases, two black lateral spots, one on each side on the middle

of the border, and an apical spot which corresponds with the

one on the dorsum; the underside and legs brown.

This is the only species of this series which has the bases

of the elytra clearly red and without marking ; it is a very

distinct species.

This species closely resembles H. reppensis, Herbst, but it

differs in the punctuation, colour of the head and thorax, and

in having a much broader prosternum. The head, face pale

sides and narrowly pale on the anterior margin, disk and base

black; the elytra with a reddish pale spot on either side well

before the apex, but nearer the outer margin than the suture,

AMIDA, gen. nov.

Type Scymnus tricolor, Hay.

This new generic name I propose for an insect which

measures 4—44 millim. and has most of its characters similar

to those of Scymnus. The eyes, however, are very different,

being large, more finely faceted, and the inner edges are

straight and parallel to each other, leaving a bilateral facial

space (very noticeable) between them ; the antenne long and

slender, 11-jointed, first two large, bulbiform, and distinctly

separate; terminal three joints form an elongate club; the

terminal abdominal segment is very narrow and transverse ;

the tibia are swollen on the outer edge, the claws with a

robust inner process.

Type P. versicolor.

This generic name is proposed for a small species which

superficially resembles a Scymnus without pubescence ; but

the eyes are small and somewhat coarsely faceted ; the antennee

longer, two basal joints bulbiform and clearly separate, after

the sixth joint the articulations become larger and form an

elongate club, the tenth and eleventh joints appear to be

connate and to form a conical mass; the anterior tibiz are

constricted at their bases, claws simple and but very feebly

enlarged at the bases; the prosternum widens and flattens

out immediately in front of the cox; there is no keel, but

in the coxal area there are two short lateral striae which

diverge anteriorly ; the mesosternum transverse and arched at

the sides, anteriorly and posteriorly straight; the elytra,

epipleural fold wide and only narrowing behind the posterior

The head clearly punctulate, brownish or testaceous, usually

darker before the neck ; the thorax yellowish brown, with a

black transverse patch before the scutellum, the patch extends

on either side to a point behind the eyes; the elytra rather

paler than the thorax, with twelve black spots—one round on

the humeral area, two other similar spots along each lateral

margin, one more oblong ‘in the centre of each wing-case,

and two sutural spots on each elytron, the first just before

the disk, the second well before the apex ; the sutural margin

is often brownish, and so also is the space between the oblong

discal spot and the marginal spot in a line with it; the legs

and surface beneath concolorous.

Shortly oval, convex, densely clothed with grey pubes-

cence; the head red, densely but minutely punctured; the

thorax black, with the lateral margin red, the red margin

widens out towards the back of the eye, rather densely punc-

tured, the punctures being distinctly largest before the

scutellum; the elytra black, with the apices clearly red,

surface punctured with rather large shallow punctures inter-

mixed with a fine punctuation ; the prosternum is bistriate,

truncate between the stria both before and behind, with the

intermediate area somewhat roughly punctured ; the meso-

and metasternum are clearly punctured and with the first

abdominal plate black, the second and third abdominal seg-

ments are infuscate in the middle, the others wholly red; the

legs and tarsi reddish brown.

black, with a transverse red band over the metasternum, band

anteriorly deeply bisinuous and externally not reaching the

epipleural margin ; at the suture a wider black margin is left,

posteriorly near the middle of the wing-case it connects with

a second rather smaller transverse band, apex widely black ;

the legs obscurely reddish brown.

[Scymnus ferrugatus, Moll (Fissly, Neu. Mag. Heft ii.

. 183, 1785), a HKuropean species, has been recorded from

fepan by Weise; but as he suggested, without any descrip-

tion, a varietal name for it, it is open to doubt whether

Moll’s species really occurs in Japan or only a species

resembling it. Illiger also gave a varietal name to an insect

he considered was 8S. jferrugatus from Siberia. I have not

included it in the list.]

Formula.—1 0 3 f 0. :

Distribution.—Mid Lias—Cornbrash, England. Lias—

Corallian, Germany and Austria.

3. Berenicea Sauvaget, sp. n.

Diagnosis.—Zoarium of large thin circular disks.

Zowcia very long, cylindrical, sometimes expanded a little

below the orifice; visible throughout their length; slightly

sinuous ; minutely punctulate.

Peristomes slightly raised, distributed regularly in a quin-

cuncial pattern.

Formula.—1 03 d 1.

Distribution.— Bradford Clay, Bradford, Wilts.

A ffinities.—This species resembles B. Archiaci in its long

zocecia, but it has no known ocecia; the zoaria are larger ;

the zocecia are longer, more sinuous, and not so markedly

radial in arrangement. It is nearer to B. Allaudi, from which

it differs in the quincuncial arrangement of the orifices and

the greater length of the zocecia.

Among the species with irregular zoaria it must be com-

pared with B. compressa (Goldf.). With this it agrees in

the length of its zocecia, their faint punctulation, and the slight

expansion just below the raised portion of the orifice. The

species differ, however, in the greater distance of the orifices

in the old species, and their very irregular distribution. One

has only to compare the crowded regular quincuncial orifices

of B. Sauvaget with Vine’s figure (op. c7t. pl. xix. figs. 3 and 7)

to see the extent of this difference.

4, Berenicea portlandica, sp. n.

Diagnosis.—Zoarium small, discoid. Zocecia arranged at

first on a somewhat flabelliform plan. Borders of zoarium a

little irregular. ‘The zoarium is a thin sheet.

Zoecia long, cylindrical ; front wall ornamented by several

sharp ridges, usually five or six on each zocecium. Zocecia

visible throughout their length.

Feristomes tlush or raised on lower margin, circular.

formula.—0-0" 0. 3d 0.

Distribution.—Portland Oolite, Tisbury, Wilts.

A fjinities.—This species greatly resembles Haime’s figure

of Lerenicea striata (Jur. Bry. pl. vii. figs. 8 a, 6), owing to

the transverse ribbing. ‘The two species are closely allied ;

thus, B. striata has a formula of 11270. The differences

between the zocecia of the two species are that those of striata

44 Dr. J. W. Gregory—A Revision

have higher peristomes and are more fusiform and_ shorter.

These seem sufficient to separate them, apart from the differ-

ences in the zoaria, which in séréatu are irregular and flabelli-

form. The specimens occur on an Ostrea found in the Port-

land Oolite at Tisbury, and they are of interest as the only

Bryozoa known from this stage in England. The species is

well marked ; its nearest Cretaceous ally is B. clementina,

@Orb.*, which is, however, nearer to B. striata. B. port-

landica differs from B. clementina in having a_ discoid

zoarium, the orifices more scattered, and longer zocecia.

zocecia flabellate and visible throughout their length. Peri-

pheral zocecia more crowded and visible only in part ; surface

lain.

P Peristomes small, slightly raised, from 4 to + the width

of those of B. diluviana.

Oecia low, rounded domes, three or four times the width

of the zocecia.

Formula.—1 0 2 7 0.

Distribution.—Cornbrash, Rushden; Bradford Clay, Brad-

ford; Great Oolite, Richmond Boring.

A ffinities—This species is characterized by the delicacy

and narrowness of its zocecia. It thus takes the place in the

Berenicea series held by S, Waltoni in the Stomatopora and

D. mettensis in the Diastopora series.

Its nearest ally is B. diluviana, from which it differs only

in the size of the zocecia and the less elevation of the peri-

stome. It differs from B. undulata (Mich.) in the absence of

the wavy ridges which occur in that species, and also by the

size of the orifices. The smallness of the apertures reminds

one of the species described as B. microstoma by Haime.

This, however, is only a synonym of B. undulata (Mich.),

while the true D. microstoma of Michelin is referred to the

genus Reptomultisparsa. It differs from this, in addition to the

generic characters, by the orifices being more crowded and

smaller, and the surface plain.

the extremities, which are crowded together; front wall

punctulate.

larly arranged, generally irregularly quincuncial, in long

is only equal to their diameter.

Formula.—2 0 1 7 2.

Distribution.—Inferior Oolite, Cotteswolds ; Great Oolite,

Richmond Boring and Bath.

A fiinities.—This species is most closely allied to B. sco-

binula, Mich. From this it differs in the much greater

crowding of the raised portions of the zocecia, and from these

being regularly quincuncial in arrangement. In B. exilis,

Reuss (B. cricopora, Vine), the distal portions of the zocecia

rise from a flat crust. In B. coartata they are so closely

packed that no flat basal expansion can be seen between them.

The species seems to me exceptionally well marked.

DOLICHOCHELIA, gen. nov.

The eye-lobes not soldered to the head; the eyes pigmented.

First antenne very elongate, with the flagellum multi-

articulate, not hirsute.

Masticatory organs in the male obsolete.

First gnathopods of the male chelate, having the three

basal joints short and little tumid, while the following three

are extremely elongated and rather slender.

Uropods biramous, the outer branch minute but distinctly

two-jointed, the inner multiarticulate.

The name (formed from doAvyos, long, and yyrx, a claw)

Ann. & Mag. N. Hist. Ser. 6. Vol. xvii. 4

50 Rev. T. R. R. Stebbing on a

points to the close relationship which this genus bears to

Leptochelia. It is, in fact, inosculant between Leptochelia,

Dana, and Heterotanais, Sars. The latter is distinguished

from the former by two characters, its subchelate first gnatho-

pods and its uropods with a two-jointed outer branch. In the

second of these characters it agrees with Dolichochelia, from

which it is strongly distinguished in regard to the gnatho-

pods. To have had to separate Dolichochelia from Lepto-

chelia merely on the ground that the minute outer branch of

the uropods is two-jointed in the one and uniarticulate in the

other, might have been necessary, but would have been a

hard necessity. The new West-Indian genus, however, is

fortunately not dependent solely on so small a difference,

being strikingly separated from both the nearly related genera

by the slenderly elongated first antenne and first gnathopods.

Dolichochelia Forresti, sp. n.

The front margin of the head-shield projects but slightly,

forming a very obtuse angle, the corners being shallowly

excavate for the ocular lobes. The part of the shield to

which the first gnathopods (or chelipeds) are attached is wider

than the front. The pleon at its base is as wide as the trunk,

but narrows distally with a gentle curve; the sixth segment,

which is very little longer than that preceding it, ends in an

obtuse angle similar to that of the frontal margin.

The eye-lobes have a convex outer margin and are not very

sharply pointed in front. The pigment is black in the

mounted specimen.

First Antenne.—These are as long as the animal from the

front of the head to the apex of the pleon. ‘The first joint is

dilated at the base, for the rest slender, its length forming

two fifths of the whole antenna. ‘The second joint is rather

less than three quarters the length of the first. The third is

a fifth of the length of the second, and so slender as to look

like a part of the flagellum, among the eight joints of which

the first is the shortest. The joints carry two or three sete

apiece, giving an appearance very unlike that produced by

the conspicuous sensory filaments in the adult males of

Leptochelia and Heterotanais.

Second Antenne.—The first three joints are very small,

together not equal to the fourth. The fifth is two thirds the

length of the fourth and is distally armed with a seta. The

minute tubercle which represents the flagellum carries two

seta. The whole antenna is shorter than the flagellum in

the first pair.

new West-Indian Tanaid. : 51

First Gnathopods.—These chelipeds are remarkable both

for the threatening gape of the chela and for their length,

which is double that of the animal’s body. The second joint

is the stoutest, yet not much dilated, a little longer than

broad. The third joint is short, almost triangular. The

fourth is of great length, narrowest near the base and nowhere

very wide. The fifth is still longer, with a curvature at its

base adapted for the folding together of these long slender

joints; its narrow immovable digit forms less than half of

the total length of the joint and ends in asort of pointed claw

over which three setules are distributed, another setule occu-

pying a small prominence of the inner margin near the

base of the claw. The movable finger is somewhat longer

than the immovable one, slender, pointed, curved, with

irregular margins.

Second G'nathopods.—As usual in this group, these are

gnathopods only in name, and differ but slightly from the

following ambulatory feet. They are scarcely, if at all, larger

than the fifth pereopods, having the second joint narrower,

but the fourth and fifth joints a little wider than is the case

in that pair.

Percopods.—The general structure is the same in all. The

second joint is the longest, in the last three pairs somewhat

dilated. The third joint is very short, the fifth joint is a

little longer than the fourth, and the sixth considerably longer

than the fifth. There are some spinules about the distal end

of the sixth joint. In the first and second pairs the finger is

small, in the other three pairs it is nearly as long as in the

second gnathopod.

Pleopods.—Al1 the five pairs are constructed as in Lepto-

chelia.

Uropods.—The peduncles are a little longer than broad.

The inner branch has six joints, of which the first is the

widest, the fourth the longest. The outer branch has two

joints, together not equalling the length of the first joint of

the inner branch. All the joints of the branches are seti-

ferous.

Length—From head to tail the specimen measured less

than a tenth of an inch.

Habitat.—The single specimen (a male) comes from An-

tigua, where it was found at Long Island, at the mouth of

Parham Harbour, in shallow water, with sandy bottom,

covered with alge, by Mr. W. R. Forrest; and I do myself

the pleasure of associating the species with the name of that

acute observer.

52 On a new West-Indian Tanaid.

From an unmounted specimen with which Mr. Forrest has

favoured me since the above description was passed for press

it appears that the lateral margins of the head anteriorly are

slightly concave, that the first three free segments of the

peron are very decidedly shorter and a little broader than

the following three, that, viewed dorsally, there is a constric-

tion between the third and fourth and between the fourth and

fifth free segments, and that the first five segments of the

pleon are slightly broader than the immediately preceding

segments of the person. In both specimens the mouth-

organs appear to be in a very rudimentary condition.

Tn his recent contribution to the Crustacea of the Plankton

Expedition Dr. H. J. Hansen gives some weighty reasons

for adopting the view that the families of the Apseudide and

Tanaide should form a separate order, which he calls ‘Tanai-

dacea, coordinate with the Amphipoda, Isopoda, and Cumacea.

T shall not easily be convinced that the new order is required.

It is much more a question of convenience than of scientific

accuracy. Though the two families in question have points

in common with the Amphipoda and Cumacea, they are

trenchantly distinguished from both of those groups. On the

other hand, they have the dorso-ventrally depressed body

which is so prevalent among the Isopoda, and in detail they

show several points of agreement with various members of

the Isopodan families. ‘Thus the peculiarity in Apseudes that

the second antenne have an exopod has its parallel in Stene-

trium and Janira. In Stenetrium, Haswell, and Phreatozcus,

Chilton, the first gnathopods have a prehensile hand to some

extent equivalent to that found in the Apseudide and Tanaidee.

In the Gnathiidew and the Cryptoniscian forms among the

Epicaridea there occur pleopods strongly resembling forms

of those appendages in the families just mentioned. The

uropods of the ‘Tanaide cannot be considered remote from those

of the Asellidee; and the coalescence of the first pereon-

segment with the cephalon is exhibited in a more or less

marked degree in the male sex of the Gnathiide.

In regard, then, to the acceptance of the proposed new order,

Tanaidacea, in exchange for the group of the Isopoda Cheli-

fera, the important question arises, cud bono? For whose

advantage will the change be made? So long as the higher

classificatory divisions are capacious, they hold out a welcome

to new discoveries ; but when their boundaries are contracted,

the next new species is liable to find itself left out im the

cold, and then perhaps a new order must be established for a

solitary form. Moreover, when the breaking-up of a fairly

Dr. A. G. Butler on new Species of Butterflies. 53

satisfactory group is once begun, the process is likely to

continue, since the importance of differences on which sub-

orders and families have been established can be magnified

at will to justify the elevation of a family to the rank of a

suborder, and of a suborder to the rank of an order.

Note on Apseudes Latreillit (Aftlne-Edwards ?).

In the description given of this species by Professor G. O.

Sars in 1880, and more fully in 1886, it is stated that the

segments of the perzeon are without ventral spines. In the

description of it by Norman and Stebbing, published in 1886,

it is said that the carapace and pereeon-segments are ‘ without

spiny armature either on the sides or ventral surface, except

that the last segment of the person has a large spine-like

projection on the middle of its under surface.” ‘These state-

ments appear to need a little modification, for, among nume-

rous specimens dredged this summer in Salcombe estuary, a

few, not otherwise distinguishable from the rest, show a

ventral spine on the fourth as well as one on the seventh

pereon-segment. ‘lhe spine in question is pointed slightly

forward, and arises from the middle of the hinder part of the

ventral surface of the segment. Being placed just between

the legs it is not always easy to detect, though its size is

considerable.

VII.— Descriptions of new Species of Butterflies of the Genus

Catasticta in the British Museum. By Arruur G.

Buter, Ph.D. &c.

THE following species have been in the Museum without

names for many years; and, as I find that they are unques-

tionably not described, I propose to name them now.

54 Dr. A. G. Butler on new Species of Butterflies.

Catasticta sinapina, sp. n.

&. Resembles C. nimbrce on the upper surface, excepting

that the central ochreous band is more distinctly divided by

the veins, the spots composing it on the primaries smaller ;

the postmedian series consists of larger spots, and the marginal

spots on the secondaries are larger; the latter wings are more

elongated at anal angle; the under surface is quite unique in

colouring, the ground-colour mustard-yellow, and the veins

and markings purplish brown; the pattern corresponds almost

exactly with that on the under surface of C. susiana.

Expanse of wings 56 millim.

Pucartambo, Peru ( Wahitely).

We purchased this insect in 1872, but at that time I was

not in a position to decide whether or no it was undescribed ;

it should stand near C. sustana.

Catasticta reducta, sp. n.

Euterpe colla, Hewitson (not Doubleday), in Coll. Hewits.

6. Pattern of both surfaces as in C. anaitis, but this

species is much smaller and has all the markings of the upper

surface ochreous, irrorated with purplish brown ; the nervures

are much more broadly blackish; the secondaries have a

marginal series of small white spots: the macular bands on

the under surface of the primaries are clear ochreous, those

towards apex being more falciform.

Expanse of wings 52 millim.

HKeuador (Buckley).

Local form boliviana.

Differs from the typical form in having all the markings of

the upper surface clear ochreous, with scarcely a trace of dark

1rroraticn.

Expinse of wings 51-54 millim.

Bolivia.

The above species is represented in Hewitson’s collection

by seven examples—four from Ecuador and three from

Bolivia—and incorrectly identified by him as Luterpe colla.

In the same drawer an example ot Doubleday’s species is

associated with a specimen of C. zancle, and wrongly iden-

tified as C. nimbice.

Catasticta strigosa, sp. 0.

g-+ Form, size, and general aspect above of C. hebra;

deep olive-brown, the lower third of the discoidal cell of

primaries sparsely irrorated with sulphur-yellow scales, the

cell surrounded by a series of longitudinal tapering rays,

sulphur-yellow irrorated with brown, the pointed extremities

of the first six of these rays being cut off by a stripe of the

ground-colour from apical fourth of costa to external angle:

secondaries sulphur-yellow, irrorated with brown, but with

the nervures and a broad external border which emits pyra-

midal spurs along the nervures deep olive-brown; three

elongated clear yellow spots terminating the second to fourth

internervular streaks: under surface similar to C. ctemene @,

but the yellow patch on the primaries broken up into narrow

streaks by the broad brown borders to the nervures.

Expanse of wings 67 millim.

Pucartambo, Peru (Whitely).

Catasticta straminea, sp. n.

Allied to C. eurigania from Ecuador, but the upper surface

deep buff or straw-yellow, with all the veins black; three

elongated spots placed obliquely on the black apical area, the

middle one large, the others small: secondaries with the

outer border broadly black, with a deep sinus in the radial

interspace.

Expanse of wings 47 millim.

Hab. ?

Two specimens of this species stood in Hewitson’s collec-

tion with two of his C. eurtgania from Ecuador and two of

C. notha from Bolivia, the label ‘ ewrtyania ” standing below

the three species. Unfortunately Hewitson neglected to label

the present species with its locality.

Family Heteropodide. By R. I. Pocock, of the British

Museum of Natural History.

[Plate VIII.]

Selenops Spencert, sp.n. (Pl. VIII. figs. 8, 8 a.)

9. Colour yellowish brown; carapace partially clothed with

white hairs, which, contrasting with the yellow of the integu-

ment, gives it a mottled appearance, a fine dark line on its

lateral edges, and the region of the eyes deeply pigmented

with black. Abdomen thickly mottled above with fine brown

and white spots ; clothed with whitish hairs below. Sternum,

56 Mr. R. I. Pocock on some

labium, maxillw, coxe, and lower surface of limbs pale yellow,

rather scantily covered with silky white hairs. Mandibles

reddish yellow, very faintly infuscate distally, sparsely covered

with longish white hairs. Palpi pale, with a fuscous spot at

each end of the tarsus. Legs with femora faintly variegated

with stripes; patella, tibie, and protarsi with a proximal

fuscous spot, the one on the protarsus very broad ; tibize in

addition with a broad band in the distal half and protarsus

with a narrower one at its distal extremity.

Carapace considerably wider than long, its width a little

less than the length of the fourth tibia ; cephalic region slightly

elevated, the face moderately high ; the clypeus about as high

as the diameter of the anterior median or posterior median

eye. The anterior medians separated by a space which is

distinetly less than their diameter, a little closer to the poste-

rior median, which are more than twice their size, and have

advanced much less to the front than is usual in Selenops,

and stand so high that, when viewed from the front, their

inferior edge is only a little below the level of the inferior

edge of the anterior median ; the anterior lateral oval, less

than half the size of the anterior median, but in the same

straight line, situated on the lower side of an elevation which

bears on its posterior lateral surface the posterior lateral eye,

which is considerably larger than the posterior median.

Inferior mandibular margin armed with 3 strong teeth in

front and 2 behind.

Palp: femur with 5 -spines above; patella with 3, one

internal larger, two median setiform; tibia with 6 spines;

tarsus with a transverse row of 6 very long spines in its

proximal half, 3 below at the apex, and 1 on the inner surface.

Some of the spines on the palp pale, some black.

Legs 4, 3, 2,1, armed above with 3 pairs of spines, those of

the anterior row black, of the posterior pale ; alsowith 3on their

anterior surface, the proximal of these pale. Patella with 1

posterior spine ; tibie of first and second legs with 7 pairs of

inferior spines, protarsi with 3 pairs; tibie of third with 2

pairs of inferior spines, protarsus with 1 pair; tibia and pro-

tarsus of fourth only weakly spined; tarsi and protarsi of

first and second weakly and biserially scopulate, of third and

fourth not or hardly scopulate.

Sternum almost circular, a little longer than wide, widest

between the coxee of the second legs.

Vulva with the form of a longitudinally oblong plate,

with its anterior two-thirds deeply hollowed with an oval or

horseshoe-shaped excavation; the plate laterally and poste-

riorly overgrown with hairs.

Measurements in millimetres.—Total length 11; length of

carapace 5°6, width 6°5; length of first leg (from base of

femur) 25, of second 26°5, of third 27:3, of fourth 28°5.

Loc. Durban (H. A. Spencer). A single female example.

Apparently resembling S. atomarius, Simon (Bull. Soc.

Zool. Fr. xii. p. 465, 1887), from Port Elizabeth, in having

the median eyes forming a strongly recurved line, but differing

in having 7 pairs of spines upon the lower surface of the

anterior tibize instead of 5, and also apparently in the form

of the vulva.

It is an interesting fact connected with Selenops that the

females of this genus do not, like Heteropoda, make a lenti-

cular cocoon and carry it about with them, but attach their

eges to some foreign object, and cover them with a sheeting

ot thin, smooth, parchment-like silk.

Palystes Johnstoni, sp. n. (Pl. VIII. figs. 1-1 c.)

9. Colour.—Upperside of legs and carapace castaneous, but

clothed uniformly with a thick layer of greyish-white hairs, a

transverse stripe of yellowish-white hairs on the clypeus ;

upperside of abdomen pale brown, deeper in the hinder half

above the anus, where the brown area is bordered by a deep

chocolate-brown sinuous edge, which separates it from the

white posterior lateral portions of the abdomen; in front the

upperside of the abdomen is ornamented with 2 fine rather

indistinct dark-coloured longitudinal lines, which meet poste-

riorly in a point; lower surface of abdomen whitish, mottled

with yellow spots ; the epigastric region blackish, but covered

with golden-yellow hairs, and behind this region there is a

narrow deep brown transverse crescentic stripe. Palpi

yellower than the legs, uniformly coloured above and below,

but the tarsal segment apically infuscate. Mandibles blackish

brown, clothed with golden-yellow hairs, but not noticeably

stiiped. Maxille with their distal third pale; labium with

pale border. Sternum clothed with yellow hairs ; 2 thickish

black stripes crossing its middle transversely, the anterior of

these in a line with the dark stripe on the second coxe, the

posterior, which is angular, each half being directed obliquely

forwards to touch the stripe in front, being similarly continuous

with the dark anterior half of the third coxe. Legs having

their cox black in front, yellow behind; femora of first and

second legs with the basal half reddish brown; all the tibia

with 2 spots of the same colour, 1 at their proximal end,

the other just past the middle; the scopule of the protarsi

fiery red, of the tarsi greyish brown, the rest of the lower

suiface of the legs yellowish white.

58 Mr. R. I. Pocock on some

Carapace as long as tibia, +4 of patella of fourth leg ;

width equalling length of tibia of third leg.

Legs 1-2, 4, 3. Femora unarmed below; tibie armed

with 6 long spines in 3 pairs, a pair springing from each

of the spots and 1 pair at the distal end; protarsi with

2 pairs of long spines in their proximal half; femora with 3

anterior, 8 posterior, and 2 superior spines, that of the fourth,

however, with only 2 posterior spines ; patella with 1 ante-

rior and 1 posterior spine ; tibize with 1 superior, 2 anterior,

and 2 posterior spines ; protarsi with 2 anterior and 2 posterior

spines.

Vulva. (As in figure.)

Measurements in millimetres.—Total length 24; length of

carapace 11:2, width 9; length of first leg 46, of second 46,

of third 34, of fourth 40.

dg. Colour as in 2, but abdomen with the pattern less

well defined, and the lower surface of the femora mottled with

yellow spots.

Palp. (As in figure.)

Measurements in millimetres.—Total length 17; length of

carapace 8°2, width’ 7; length of first leg 45, of second 43:5,

of third 32, of fourth 38.

Loc. Zomba, 3000-9000 ft. (H. H. Johnston): types.

Also an immature specimen of apparently the same species

from Ugogo (Emin Pasha).

This species seems in some respects to resemble P. Héohneli

of Simon (Ann. Soc. Ent. Fr. 1889, p. 129) from Kilima

Njaro, the resemblance between them being especially

noticeable in the colour of the legs. It is to be observed,

however, that Simon makes no mention of the banding on

the sternum or coxze, and according to the measurements the

first and fourth legs are almost equal in length.

Palystes Elliot’, sp. n. (Pl. VIII. figs. 2, 2 a.)

Closely allied to P. Johnston, but having more black upon

the maxille and sternum, only the distal tourth of the lower

surface of the first and second femora palely yellow, and a

broad brown band running backwards on the ventral surface

of the abdomen from the epigastric fold to the spinners. The

vulva is also quite distinct (see fig. 2).

Loc. Uganda, KE. Africa (G. F. Scott Elliot).

Palystes Spenceri, sp.n. (Pl. VIII. figs. 3, 3a.)

2. Upperside of trunk and limbs clothed with dirty

new South-African Spiders. 59

yellowish-brown hairs, the legs faintly mottled with darker

spots; the carapace without distinct pattern, sometimes, how-

ever, with a paler median band and a paler marginal line ;

the clypeus with a distinct white band, which is thickest in

the middle. The abdomen ornamented above as in P, John-

stont, but the distinction between the brown patch and the

sides of the abdomen less well defined; the sides and lower

surface a uniform yellowish brown. Mandibles not striped,

black, but clothed with whitish-yellow hairs. Palpi ochre-

yellow ; tarsus distally fuscous below. Maxillee and labium

as in P. Johnston’. Sternum yellow, with a single fuscous

band crossing it in a line with the dark front half of the

second coxe. Coxe ot legs whitish yellow, with their ante-

rior third blackish brown. Femora of first and second pairs

with their basal half or almost two thirds deep reddish brown,

the rest of the segment bright yellow, mottled with small

brown spots ; femora of third and fourth yellowish, mottled ;

patella bright yellow below; tibie also bright yellow, with a

large basal brownish-red spot, and a second just past the

middle; these spots sometimes rather indistinct upon the

third and fourth legs. Protarsal and tarsal pads fuscous.

Mandibles armed as in P. Johnstoni. Legs and palpi of the

same relative length and spine-armature as in that species ;

but the examination of a large series of specimens shows

that the number of spines is not quite constant.

Vulva. (As in figure.)

Measurements in millimetres.—Total length 39°53; length

of carapace 14, width 12; length of first leg 55:5, of

second 55, of third 41, of fourth 48.

6. With the carapace browner on the summit than in the

female; the posterior brown patch upon the abdomen not

defined. ‘The 4 pairs of femora almost of the same colour,

being a brownish yellow, mottled with smaller dark spots.

Palp. (As in figure.)

Measurements in millimetres.—Total length 23; length of

carapace 11, width 9; length of first leg from base of femur

54, of second 53°5, of third 39, of fourth 46, tibia of

fourth 11°8.

Loc. Durban. A large number of specimens including the

types obtained by Mr. H. A. Spencer.

Judging from the list of localities from which the Museum

has received this species, it appears to be widely distributed

in the south-eastern parts of Cape Colony. I cannot, how-

ever, discover that it has yet received a name, unless, indeed,

the Heteropoda natalia of Karsch (Zeits. ges. Naturwiss.

1878, p. 772) be the same species. This last-named form

60 Mr. R. I. Pocock on some

will probably be found to belong to Palystes, seeing that it

has the white clypeus, the banded sternum, and the eyes of

the front row of the same relative size as in the other South-

African representative of this genus.

Palystes lunatus, sp.n. (Pl. VIII. fig. 5.)

Colour.—Carapace chestnut, clothed with yellowish-brown

hair, with a fine white median line and the usual white

clypeal band; mandibles black, clothed with yellowish-brown

hair, with the white stripes scarcely apparent ; legs and palpi

chestnut, clothed with yellowish-brown hairs above; coxe

with only their anterior surfaces infuscate; femora of a uni-

form yellowish brown below; pateile whitish yellow; tibiz

banded as usual with fuscous and whitish yellow; sternum

clothed with yellow hairs, but marked in addition with 2

transverse fuscous bands which fuse in the middle; labium

and maxilla black, chestnut only at the tips; abdomen with-

out very definite pattern above, obscurely mottled, deeper

coloured posteriorly, and marked with 2 longitudinal

blackish stripes in front; pale yellowish brown below, with a

short narrow transverse black band in front of the epigyne,

and a broad whitish crescentic one behind it, the rest of the

area between the epigastric fold and the maxille marked with

a few whitish spots and 4 fine longitudinal fuscous bands.

Vulva. (As in figure.)

Measurements in millimetres.—Total length 29; length of

carapace 12°5, width 10; length of first leg (from base of

femur) 46°5, of second 46:5, of third 38, of fourth 42°5.

Loc. §. Africa (Dr. Quatn).

Differs from P. Spencert in having 2 transverse fuscous

bars across the sternum, the femora of a uniform tint. below,

a deep transverse crescentic band behind the epigastric fold,

and the form of the vulva; in the latter characteristic, as

well as in the colour of its sternum and femora, it also differs

from P. superciliosus of L. Koch.

sternum with a single dark band across it, and the lower sur-

face of the femora variegated as in P. Spencer?, the basal half

being blackish and the distal bright yellow, although mottled.

In one of the specimens the posterior end of the abdomen is

ornamented above very much as in the figure of P. super-

ciliosus published by Koch, but in two others this pattern is

not visible.

Vulva small, pale-coloured, represented by a horny trans-

verse bilobed plate, something like that of P. superciliosus of

Koch (op. cit. pl. 1x1. fig. 1a); but the anterior lobes much

shallower. There are, moreover, no posterior lobes and no

transverse bar such as Koch has depicted.

Length 28 millim. ; length of cephalothorax 12, width 9°5;

length of first and second legs 42, of third 31°5, of fourth

36°5.

Loc. Port Elizabeth (1. A. Spencer).

Three apparently adult females were obtained at the above

locality. ‘They appear to be very nearly allied to P. super-

ciliosus of Koch, but seem quite distinct, provided that

Koch’s figure of the vulva of superciliosus is correct.

Panaretus (?) distictus, sp.n. (PI. VIII. figs. 7, 7 a.)

?. Colour.—Carapace pale castaneous, covered with pale

yellow hairs intermixed with rather stouter black ones; in the

cephalic region there are some longish sete, black at the base

and pale distally ; faint lines of black pigment radiating from

the fovea; the lateral margin posteriorly narrowly black, the

cephalic region mottled with small yellow spots; many

longish yellow hairs between the eyes, but no white clypeal

band. Mandibles pale castaneous, clothed with white or

black-and-white hairs, and variegated with small black spots.

Labium, maxilla, and sternum pale yellow, clothed with white

hairs, with a few black-and-white ones intermixed ; coxe of

the same colour, but variegated with small black spots ; legs

ferruginous or ochre-yellow, not noticeably banded, but

mottled above with minute whitish spots; the femora mottled

below with black spots ; abdomen reddish brown above, finely

mottled with minute black and white spots; yellowish white

laterally and below and spotted with black, and furnished on

each side of the spinners with a large elongate but irregularly

shaped black patch, which is emphasized above by a fine

border of white hairs.

Carapace very high in its posterior half, lightly convex

towards the ocular area, cephalic region narrower ; its length

just exceeding that of the fourth tibia. Hyes of posterior row

subequal in size and evenly spaced, forming a slightly re-

curved line ; those of the anterior row also slightly recurved

of the hinder row, but much smaller than the anterior laterals

and considerably nearer to them than they are to each other,

the space between them being about equal to their diameter ;

space between the anterior and posterior lateral a little greater

than the diameter of the former; the clypeus a little longer

than the diameter of the anterior lateral eye.

Legs long and slender, 2, 1, 4, 3; their spine-armature

approximately the same as in Palystes Johnston? and the rest.

The vulva of large size and projecting vertically downwards.

(For structure, see figure.)

Measurements in millimetres.—Total length 13; length of

carapace 6, width 5; length of first leg (from base of femur)

24, of second 24°5, of third 19, of fourth 21.

Loc. Kast London (H. A. Spencer).

Judging from M. Simon’s diagnosis of Penaretus, this

species differs from the Oriental members of the genus in

having the legs longer and the mandibles weaker, less geni-

culate, and normally hairy from base to apex.

Olios Spencert. (Pl. VIII. fig. 6.)

2. Colowr.—Carapace pale castaneous, clothed with whitish

hairs; mandibles black, maxille and labium chestnut ; abdo-

men clothed above with yellowish-white hairs, with a median

black stripe consisting of triangular spots, and mottled at the

sides with blackish spots and short stripes; pale below,

vulva deep black. Palpt reddish yellow, tarsal scopula

fuscous; legs reddish yellow, clothed with yellowish-white

hairs, scopulz fuscous; tibie with two faint fuscous bands.

Carapace as wide as long; moderately convex, its width

just equal to the length of tibia of first leg. yes of poste-

rior row straight, si.bequal, and nearly evenly spaced ; eyes

of front row closer together, subequal, the median a little

nearer each other than each is to the lateral, the space between

median and lateral about equal to a diameter.

Mandibles sparsely hairy ; armed below with 4 teeth be-

hind and 2 in front.

Failp: femur with a cluster of 5 spines above distally ;

patella and tibia with 1 external and 1 internal; tarsus with

1 external and 3 internal. Legs 2, 1, 4, 3; the second

excelling the first by its tarsus; the third and fourth only

slightly unequal; femora of first, second, and third armed

above with 8 spines (3, 2, 3), of fourth with 6 (3, 2, 1);

new South-African Spiders. 63

tibize of first, second, and third also armed with 8 spines, 2 in

front, 2+2 below, 2 behind; tibia of fourth with 6 spines,

the posterior pair missing ; protarsi also with 8 spines, 2, 2

below, 2 in front, and 2 behind; that of the fourth leg with

some extra apical spines.

Abdomen elongate oval. Vulva of large size, occupying

the whole of the middle of the epigastric plate, nearly circular,

its posterior border emarginate, the middle of the emargination

deeply notched, the notch passing into a deep sulcus, which

divides the vulva into two halves; the surface of the plate

marked with a deep oval excavation.

Measuremenis in millimetres.—Total length 15°5; length

and width of carapace 7 ; length of first leg 27, of second 29°5,

of third 21°5, of fourth 22:5.

Loc. Durban (H. A. Spencer). A single female specimen.

Mr. H. A. Spencer also obtained in S. Africa specimens

of the two following species of Heteropodidee :—

1. Palystes megacephalus (C. Koch), Die Arachn. xii. p. 25

(1848) (Ocypete).

Loc. Port Elizabeth. Adult male and female.

This species is, I think, generically distinct from the rest

of the §.-African species of Palystes. ‘The carapace is both

higher and longer, the width falling considerably short of the

distance between the posterior border and the eyes of the

hinder row. These eyes, too, are not evenly spaced as in

Palystes, the distance between the two medians being notice-

ably less than that between the medians and the laterals.

The legs, moreover, are distinctly less ‘ laterigrade ”’ than is

usual with the Heteropodide.

2. Palystes castaneus (Latr.), (Pl. VIII. fig. 9.)

Thomisus castaneus, Latr. Nouv. Dict. Hist. Nat. xxxiv. p. 30 (1819)

(teste Simon).

Olios castaneus and fuscus, Walck. Ins. Apt. i. pp. 571-573 (1837)

(teste Simon).

Ocypete melanogaster, C. Koch, Die Arachn. xii. p. 31 (1845).

Ocypete nobilis (Fabr.), C. Koch, wid. p. 37, 2 (probably not nobilis of

Fabricius, which is said to be Indian).

Mr. Spencer obtained three examples of this handsome

species at Cape Town.

In the figure of the vulva that L. Koch has published (Die

Arachn. Australiens, pl. lx. fig. 46) the median notch on the

64 On some new South-African Spiders.

posterior border should have been represented as much deeper

and angular, and the ridges defining the two anterior de-

pressions as much stronger.

In addition to being smaller than the female, the male

differs in having the lower surface of the femora white, but

rather thickly mottled with small brown spots—these seg-

ments, at least on the anterior two pairs of legs, being in the

female reddish brown, and not spotted. The male, in fact,

agrees so closely with the description of Ocypete melanogaster

of C. Koch (Die Arachniden, xu. p. 31) that I have not hesi-

tated to regard the latter as the male of castaneus.

The palpus is distally much enlarged, the tarsus bearing in

the middle of its external edge a smooth black excrescence ;

the external portion of the bulb consists of a swollen semi-

circular densely coriaceous skeletal piece, and from this three

long processes pass forwards to the apex of the alveolus, the

external of these being membranous and fimbriated, the

median straighter, more horny, and apically hooked. The

proximal end of the tarsus narrowed to form a slender neck.

The prominence on the tibia very stout, and bearing one long

process, which curves abruptly inwards and supports on its

base an angular tooth, while a third strong, hooked, but short

tooth rises trom the external angle of the prominence.

IX.—On a new Species of Hyleccetus (Lymexylonide)

from Japan. By G. Lewis, F.L.S.

I rounD only one species belonging to the Lymexylonidx

in Japan, but it was widely distributed; my most southern

specimens were taken on the heights of Ichibuyama, near

Yuyama, lat. 32°, and the most northern at Sapporo, lat. 44°.

In the Munich Catalogue, 1869, there are only twenty-two

species of Lymexylonide given, and these are assigned to

three genera—Atractocerus, Hyleceetus, and Lymeaxylon. It

is most probable that a species of Lymexylon is to be found in

Japan, and it is reasonable to look for and expect to find a

species of Atractocerus in the southern provinces or in the

group of islands lying to the south of Kiushiu, as Atracto-

cerus contains species having a wide range, and several are

known to occur in the islands of the Kastern Archipelago.

Hyleceetus cossis, sp. n.

Elongatus, parallelus, testaceus, pubescens ; capite dense punctato,

opaco, infuscato vel nigro; thorace inequali, vago haud dense

punctato ; elytris obsolete 3-costatis, apice infuscatis.

L, 10-16 mill.

Elongate, parallel at the sides, brownish or reddish yellow,

head opaque, thorax and elytra somewhat shining; the head

densely punctate, punctures subocellate, with the narrow inter~

stices between them raised and running together, black, but

rarely infuscate, and in one large female the head is reddish

between the antenne and behind the eyes and the neck is

red; the thorax uneven, punctures shallow and not closely

set, interspaces smooth, anterior angles rounded off, posterior

angles better marked; the scutellum tripartite, obtuse behind,

with a carina on the anterior median area which anteriorly

splits into two (perhaps of use for stridulation); the elytra

vaguely 3-costate, interstices roughish, finely and rather

densely punctulate, apices infuscate ; the antenns and mouth-

organs reddish brown, or sometimes dusky, the large palpi in

male black; the legs brownish yellow. The female, when

the surface is not abraded, has the head thickly hirsute.

This species doubtless varies considerably in size; the

measurements given above are taken from eight examples

only.

X.—Description of a new Species of Thauria (Moore), a

Genus of Amathusiine. By Pare Crowtey, F.L.S. &e.

Thaurta intermedia, sp. n.

Male.— Upperside. Fore wing deep brown, slightly shot

with purple, the base ferruginous brown, crossed by a broad

oblique creamy-white band from the costa just beyond the

cell to the outer margin below first median nervure; two

subapical spots, the upper creamy white, the lower less

defined and tinged with blue. Hind wing deep brown, the

base suffused with ferruginous brown; the apex and the anal

third from discoidal nervule to the anal angle rich orange-

brown.

Underside. Similar to T. pseudalaris, the band of the fore

wing being about double the width and the ocelli of the hind

wing being much larger and more pronounced.

Expanse 4°5 inches.

Hab. Burma and Tenasserim.

In collections Crowley, Adams, and Brit. Mus.

This species has hitherto been confounded with T. pseud-

alaris, and is mentioned by Messrs. Elwes, De Nicéville,

Moore, and Distant as such. It is at once distinguished from

the true pseudalarts, which occurs in Perak, Malacca, and

Salanga, by the much greater breadth and paler colour of the

band.

XI.—A List of the Species of Amphidromus, Albers, with

Critical Notes and Descriptions of some hitherto undescribed

Species and Varieties. By Hucu FULTon.

[Plates V.-VII.]

Havine had opportunities of examining a large number of

specimens, including most of the types, of this admittedly

difficult genus, I have thought that a list of all the known

species might be useful. I have endeavoured to arrange the

species according to their affinities, and have given a figure

of all the unfigured species. The genera or subgenera

Pseudopartula and Beddomea are omitted from this list, the

species of which have sometimes been included with Amphi-

dromus, but they appear to me to be, from their concho-

logical characters, sufficiently distinct to stand apart.

Species of Amphidromus, Albers. 67

My thanks are due to Prof. A. Lang (for permission to

view Mousson’s types), Prof. Dr. E. von Martens, Dr. Aug.

Brot, and M. Jules Mabille (for kind assistance while

examining specimens at their respective museums). Iam also

indebted to Mr. 8. Hansen, of Copenhagen, for comparing

specimens with Miiller’s types, and to Dr. Jousseaume for

notes on A. Perriert and A. hemicyclus of Rochebrune.

Lastly, I am especially indebted to Mr. Edgar A. Smith, of

the British Museum, without whose kind assistance in giving

me free access to books and specimens I could not have

compiled this list.

Loe. ?

The type has been lost, but the uniformly yellow-coloured

specimens, figured as above mentioned, are accepted as agreeing

best with Linné’s description. Martens’s obesus is a small

form, generally somewhat broader in proportion to its length

than typical perversus, but agreeing perfectly with it in

other respects.

A. perversus, var. tenera, Martens, Ost-Asien, p. 350.

A very thin shell, of the form of typical perversus and of a

pale yellow colour.

A. perversus, var. chloris, Reeve, Con. Icon. 1848, Bul.

fig. 223.

Loc. Malay Peninsula.

Typical specimens are of a narrower form than perversus,

and have a narrow white band below and encircling the suture ;

except for the last-mentioned character there is hardly any

difference suflicient to separate this from typical perversus—

that is, when one has a series of specimens under examination.

A. perversus, var. entobapta, Dohrn, Nach. d. deut. Gesell.

Loc. Paragua Island.

The greater size of aperture in proportion to the length of

shell and a rather coarse oblique striation separate this variety

68 Mr. H. Fulton on the

from perversus. The deep yellow colour inside aperture is

not always present, some specimens I have from Busuanga

Island being quite white throughout.

=H, dextra, Chem. ix. figs. 1210, 1211.

=H. aurea, Fér. Hist. pl. exlviii. figs. 1-3.

Loc. ?

A very unsatisfactory variety : the figure in ‘ Ost-Asien’ is

probably badly coloured, and it is difficult to say to which

variety of perversus it belongs ; the figure referred to in Fér.

is a typical perversus; but neither agree with the H. devtra

(Chem. ix. figs. 1210, 1211), which does agree with a specimen

of mine identified by Prof. von Martens as being his var.

aurea. This shell is a rather small globose form of perversus,

of a uniform golden-yellow colour.

A. perversus, var. infrapicta, Martens, Ost-Asien, p. 344,

pl. xx. figs. 1 and 9.

Differs from perversus in having the lower part of the last

whorl covered with reddish-brown stripes and spots, which

are often interrupted by a narrow yellow spiral band. Closely

allied to interruptus of Miller, but smoother.

Miiller’s type, as figured in Chem. figs. 1213, 1214, is a

decorticated specimen, with fewer markings than in most

specimens. Lamarck’s sultanus was founded upon specimens

of this variety in good condition.

Loc. Natuna Islands.

Like interruptus, but generally somewhat larger, de-

pressed at the sutural area; coloration varies from white,

with one oblique dark brown stripe, to specimens coloured

like melanomma, except that the stripes do not extend right

across the whorls, but stop short, leaving a broad white band

below the suture.

A. perversus, var. strigosa, Martens, Ost-Asien, p. 346, pl. xx.

Very near interruptus and melanomma, but the whole shell

is closely covered with oblique dark reddish-brown stripes.

According to Martens’s figures this is very variable in

form, but chiefly characterized by having a broad white band

below and encircling the suture. ‘To me the figure in Reeve’s

‘Tconica’ represents this variety ; the other figures which were

afterwards referred to this variety by Martens appear to me

to be different.

Variable in size and also somewhat in form, but easily

distinguished by its coloration. The andamanensis was

described by Pfeiffer from three small specimens from

Mousson’s collection bearing a label with the locality Anda-

man Islands; but this species has never been found there:

the small form has been found at Sarawak and Sirhassen

Island by Mr. Everett; it is generally of a darker colour

than the larger forms, three specimens in the Geneva Museum

being almost black.

Dr. Méllendorff’s annamiticus, var. roseotincta, is without

the usual dark brown fillet at apical whorls, the apex being

uniformly rose-coloured. I find, however, that this slight

character is not constant.

4. A. alticola (Boettger, MSS.), Fulton. (Pl. VI. figs. 5,

5a.)

Loc. Java.

Dextral and sinistral, thin, obliquely striated, uniform

yellow, shining, impressed with a thread-like white fillet at

the suture; umbilicus almost or completely covered; lip

white, somewhat reflected ; columella either erect, arcuate, or

somewhat distorted; whorls 6, slightly convex, last whorl

equal to two thirds of whole length of shell.

Long. 37 millim., maj. diam. 20 millim.

Easily separated from all other known species of this group

by its small size, narrow form, and thin substance.

Group of A. janus.

Loe. ? (not New Hebrides).

In Mousson’s collection I saw two specimens quite agreeing

with janus, except that the characteristic spiral bands were

absent, the specimens being of a uniform yellow colour, with

a narrow white band at the suture.

6. A. enganoensis, Fulton. (Pl. VI. fig. 11.)

Loc. Engano Island, W. Sumatra (Dr. G. Modigliani).

Shell sinistral, oblong-ovate, perforate, solid, shining,

obliquely striate ; ground-colour either yellow or rich brown,

sometimes in the latter case with two or three darker brown

spiral bands; whorls 7, convex, suture strongly impressed with

a spiral narrow white band ; lip and columella broadly ex-

panded and slightly reflected, margins joined by a thin trans-

parent callus, columella more or less deflected at point of

insertion.

Long. 49 millim., maj. diam. 28 millim. (brown specimen

Long. 49 millim., maj. diam. 27 millim. (yellow specimen

Long. 49 millim., maj. diam. 27 millim. (banded specimen

This species is in form like a large janus, but easily dis-

tinguished by its broadly expanded lip and columella, its

different coloration, and the absence of the dark colour on

parietal wall.

This may possibly be but a variety of perversus, but all

the specimens I have seen appear to be different in form as

well asin colour. There are two very large specimens in the

British Museum, similar in size and form of aperture to

typical aéricallosus, but in other respects like mundus.

number of specimens) I am unable to separate this from

palaceus.

almost covered with variegated green and red-brown oblique

markings. The spiral lines, as seen in the type specimen,

The Kobeltt of Rolle is a pale yellow specimen without the

dark purple-brown bands. Martens’s subconcolor is near

Kobelti, but narrower, and with two very faint yellow bands

encircling last whorl, which are not shown in the figure.

This species varies very much in its colour-banding; but

even in the very pale varieties, where the dark-coloured

bands are wanting, one can trace the characteristic pale

orange-yellow bands that encircle the whorls.

Shell sinistral, ovate-conic, thin, obliquely striate, shining,

brown stripes, which are interrupted by a spiral yellow band ;

lower part of last whorl encircled by three dark brown bands,

which are separated by two other bands, the lower broad and

light red, the upper narrow and of a yellow colour; whorls 6,

slightly convex; columella thin, straight; lip slightly ex-

panded, flesh-coloured.

At first I thought this to be the typical contrardus as figured

in Chemnitz, which figure (except for its thin columella) it

very much resembles. After sending specimens to Copen-

hagen for comparison with Miiller’s type, I find that the

generally accepted form of contrarius is the true one, a good

figure of which appears in the ‘ Voy. au Péle Sud’ by Homb.

that species.

Species of Amphidromus, Albers. 89

This species is described from two specimens in my collec-

tion: one is evidently full-grown, except that the lip is not

expanded ; this specimen has its green epidermis in fine con-

dition. The other specimen is perfect in form, but rather

worn, and only shows traces of the epidermis. It chiefly

differs from Mouhoti in its dark brown lip and columella, its

longer form, and in not being subangulate at the periphery.

Named after Mr. Edgar A. Smith, of the British Museum.

55. A. eruentatus, Morelet, Sér. Conch. de Moll. 1875, pt. 4,

p. 264, pl. xu. fig. 5.

Loc. Cambodia.

Besides the type specimen I have seen only three others of

this species; all are very much worn, but agree in having

the broadly expanded lip and the characteristic deep purple

colour on the lip, columella, and parietal wall.

56. A. roseolabiatus, Fulton. (Pl. VI. fig. 8.)

Loc. Siam.

Shell sinistral, ovate-conic, moderately umbilicated, rather

solid; whorls 63, slightly convex; obsoletely angulated at

the periphery ; white above, lower whorls pale lemon, with

oblique close-set light green lines ; spirally striated ; lip and

columella pink, expanded, lip somewhat reflected ; interior of

aperture white.

Long. 36 millim., maj. diam. 21 millim.

This species is described from two specimens (young and

adult); they were upon a tablet with the type of Mouwhot?,

from which they can be separated by the much broader form,

the more distinct spiral striz, and by the absence of markings

on the upper whorls.

60. A. glaucolaryne, Dohrn, Proc. Zool. Soc. 1861, p. 207,

pl. xxviv fig. 7.

Loc. Siam.

Prof. von Martens, in his ‘Ost-Asien Moll.’ p. 80, makes

this species a variety of Schomburgki; he also considers the

type of glaucolarynx to be an abnormal form, and thereupon

drops Dohrn’s name altogether, naming the small form of

glaucolarynez as Schomburgki, var. fasciata, Mart. Until more

material has been examined I do not think one can say that

the typical glaucolarynez is abnormal; the type is 48 millim.

in length, and there is in the British Museum a specimen

45 millim. long, only 3 millim. less. The small form which

Martens considers the normal form of glaucolarynx I think is

better classed as a variety, but not of Schomburgki, which I

consider to be quite distinct from glaucolaryna.

A. glaucolarynz, var. fasciata, Martens. (Pl. VII. fig. 3.)

= Schomburgkt, var. fasciata, Mart. Ost-Asien, p. 80.

= Perriert, Rochebrune, Bull. Soc. Philom. 1882, p. 71.

Loc, Siam.

Like typical glaucolarynz, but only about 35 millim. in

length, and with a spiral cream-coloured band just below the

periphery. I was unable to see the type of Perriert myself,

but Dr. Jousseaume, to whom I sent a specimen of the above

for comparison, writes that he is unable to separate Perriert

from this variety.

Species of Amphidromus, Albers. 91

A stout shell, with a well-developed and thickened lip ;

last two whorls almost covered with oblique bright green

stripes ; lip, columella, and callus of a purple colour.

Pfeiffer’s Crossei is evidently a small and decorticated

specimen of Schomburgki.

allied to yanus.

XII.— Description of a new Species of Opisthostoma.

By G. B. Sowersy, F.L.S., F.Z.8.

In the ‘Annals & Magazine of Natural History,’ October

1894, Mr. E. A. Smith gave a list of the Bornean species of

this curious and interesting little genus of terrestrial

Mollusca. Including four new species then described, the

total number was fifteen, of which all but two have been

discovered within the last five or six years. I have nowa

new species to add to the list, which I propose to call

Opisthostoma Lintere.

Testa ovato-conica, elata, rufescens vel alba, anguste perforata ;

spira leviter convexa; anfractus 7, convexi, apicales leves, caeteri

lamellis numerosis tenuissimis pellucidis undulatis in medio plus

minusye productis instructi; anfractus ultimus versus aperturam

valde contortus, retrorsus et solutus, lamellis antice productis,

cristam basalem formans ; apertura circularis; peristoma leviter

reflexum, extus lamella tenuis, expansa, antice et postice producta

marginata.

Alt. 4, diam. maj. 4, min. 2.

Hab. Sarawak.

This pretty species will best be recognized by a com-

parison with O. pulchellum of Godwin-Austen, to which in

many respects it is similar. It is decidedly higher in the

spire, the whorls are less distinctly angular, and the contorted

whorl descends much more abruptly and deeply.

XIII.— New Generaand Species of Pyralide, Thyridide, and

Epiplemide. By W. Warren, M.A., F.E.S.

| Continued from vol. xvi. p. 477. |

MACROSPECTRODES, gen. nov.

Fore wings elongate; costa straight till shortly before

apex, which is prominent but blunt; hind margin decidedly

oblique, faintly curved. Hind wings broad, with rounded

Genera and Species of Pyralide. 95

hind margin. Antenne of male simple, filiform; labial palpi

short, broad, terminal joint very minute; maxillary palpi

slender, filiform; tongue well developed; forehead somewhat

prominent. Neuration: fore wings, cell half as long as

wing ; discocellular vertical, hardly concave ; first median at

four fifths, second just before, third from, the lower angle of

cell; lower radial just beyond the angle; upper just below

the top angle; fifth subcostal from the angle; third and fourth

stalked from the angle; first and second free from the cell.

Hind wings with cell not half as long as wing; disco-

cellular concave, the lower arm more oblique. Costal and

first subcostal long, stalked, second subcostal from upper

angle of cell; radial and third median both from lower angle

of cell, second just before the angle; first at three fourths; on

the abdominal margin between it and the third internal vein

is a long oval semitransparent space, the edges of which are

thickened.

Type Macrospectrodes subargentalis, Snell. (Botys).

Genus Opsrzotys, Warr.

Opsibotys profusalis, sp. n.

Wings reddish ochreous, suffused with greyish brick-red,

and with the lines dull brick-red ; costa deeper brick-red ;

first line at at one fourth, curved outwards, then vertical; a

narrow lunular discal mark; exterior line at three fourths,

running at first slightly obliquely outwards, then forming

a wavy outward sinus approaching the hind margin,

running in basewards along first median, and again vertically

wavy beneath the discal mark to the inner margin; apex and

hind margin paler, less suffused; fringes concolorous, with a

row of very neat black dots along their base. Hind wings

like fore wings, but with the costal region broadly whitish ;

the basal fringe-dots larger and longer. Head, thorax, and

abdomen reddish ochreous, suffused with brick-red. Under-

side glossy, pale, the fore wings slightly reddish.

Expanse of wings 20 millim.

One male from the Khasias.

Nearest to rubellalis, Snell., and also allied to affusalis,

Guen., and diffusalis, Guen.

Genus GLAUCONOE, Warr.

Glauconoé atrigenalis, sp. n.

Fore wings dull grey, dusted with fine darker grey atoms ;

first line quite near base, fuscous, wavy; second line at

96 Mr. W. Warren on new

three fourths, fuscous, wavy, and dentate, running at first

outwards for a short distance, then inwards again, then

forming a rounded sinus on the medians, and reaching inner

margin at two thirds; a curved black discal spot and a

minute dark spot between it and first line ; fringe concolor-

ous; a series of fine short dark lines at the end of the veins.

Hind wings with discal spot round, and exterior line like that

of fore wings; costa whitish. Head, thorax, and abdomen

dark grey; palpi dark brown-black. Underside dull white,

with all the markings clearly defined as blackish spots.

Expanse of wings 36 millim.

One male from Cherra Punji.

Genus PALiIGA, Moore.

Paliga rubicundalis, sp. n.

Fore wings yellow, with rosy markings ; these markings,

consisting of two stigmata in the cell, a denticulated inner,

exterior, and subterminal line, are much the same as in

damastesalis, but as the spaces between them are varied with

rosy dashes and all the veins are rosy, the aspect is much

gayer than in that insect ; the basal and dividing line of the

fringes is also rosy ; costa broadly dull brown. Hind wings

yellower, with the fringe-lines and the submarginal space

rosy, and a rosy curved central line, containing a diffuse rosy

spot within the central sinus. Head, thorax, and abdomen

yellow, tinged with rosy ; face brown, like the costa of fore

wings. Underside dull yellowish, with the costa and hind

margin brownish grey, and a similar coloured central blotch,

Expanse of wings 24 millim.

Khasia Hills.

Distinguished at once from damastesalis, to which it is

most nearly allied, by the rosy colouring. It is probably the

insect referred to by Snellen (Tr. HK. 5. 1890, p. 575) as

damastesalis.

Genus UpgA, Moore.

Udea nigrostigmalis, sp. n.

Fore wings luteous, with an undertone of yellowish ; inte-

rior line in the single example seen obsolete ; exterior line

denticulate, slender, blackish, from costa at two thirds to inner

margin at two thirds, curved outwards to below the middle,

starting from a black costal spot; two smaller costal black

spots beyond it, the costal intervals yellowish; fringe leaden

grey, with a row of black dots before their base; reniform

Genera and Species of Pyralide. 97

mark filled up with black. Hind wings cinereous, with a

very indistinct denticulated outer line, and the row of dots

before the fringe as in fore wings. Head and thorax con-

colorous with fore wings; abdomen dark cinereous, with the

segmental divisions paler. Underside of fore wings deep

cinereous, of the hind wings dull straw-colour with the

markings darker ; costa of fore wings yellowish from middle

to apex.

Expanse of wings 18 millim.

Several from the Khasia Hills.

Genus Eurycreon, Led.

Eurycreon ? rubralis, sp. n.

Fore wings reddish brown, thickly scaled, with no markings

but an indistinct exterior line, slightly denticulated, which

rises on the costa at three fourths, from an oblique dark pale-

edged streak; fringes very wide, red-brown, with a line of

darker red dots at the base, those near the apex being edged

with whitish. Hind wings whitish, becoming rather reddish

towards apex and hind margin. Head, thorax, and abdomen

concolorous. Underside glossy pale reddish ochreous.

Expanse of wings 12 millim.

One male from the Khasias.

The forehead is much produced below, forming a shelf

which is in the same plane with the top of the much pro-

longed and stout palpi; the antenne are thick, lamellate.

Having only one example, and that somewhat damaged, I

refrain from making a new genus for the species, as will

probably have to be done later on.

Genus PACHYZANCLA, Meyr.

Pachyzancla honestalis, sp. n.

Fore wings pale fawn-colour, tinged with rufous; the

costa broadly and the hind margin diffusely darker tinted ;

markings fuscous; an oblique basal line, a curved sinuous

exterior line, and two cell-spots; hind margin, immediately

before the pale basal line of fringes, darker. Hind wings

paler, semidiaphanous, with dark discal spot and central line ;

a dark shade along the hind margin. Head and thorax

concolorous with fore wings, abdomen with hind wings.

Underside paler and duller, with the markings indistinct.

Expanse of wings 20-22 millim.

Khasia Hills.

98 Mr. W. Warren on new

Genus HEeDYLEPTA, Meyr.

Hedylepta confusalis, sp. n.

Wings dingy fuscous, with the lines indistinct, darker ;

basal line at one fourth, vertical, exterior line at three fourths,

vertically wavy as far as the first median, along which it runs

inwards, and reaches the inner margin at two thirds; discal

spot lunular, more distinct; fringes concolorous, with a

narrow pale basal line, before which the extreme hind margin

is darker: hind wings the same, butslightly paler; the fringe

whitish in apical. half. Head, thorax, and abdomen all

fuscous. Underside dull greyish fuscous.

Expanse of wings 34 millim.

Two males from Japan.

A very dull-looking and inconspicuous insect, with the

markings as in ¢ristrialis, Bremer, with which it agrees in

size.

Hedylepta ochrifuscalis, sp. n.

Nearest to preterttalis, Wlk., and misera, Butler, but

rather larger, and with a strong tinge of fulvous ochreous,

thereby appearing much paler than either of the above-

named species ; this paler tint is especially marked along the

costa, hind and inner margins of the fore wings, and on the

thorax and abdomen; the hind wings remain greyer. Fringe

of fore wings concolorous, with a thick dark line along their

base and a narrower dark line before the base along the hind

margin; fringe of hind wings dull whitish, with the same

lines. Underside duller, with basal two thirds of both wings

rather darker but diffusely edged.

Expanse of wings 32 millim.

Several from the Khasia Hills.

discocellular angulated, first median at two thirds, second

from lower angle; third and lower radial close together

shortly above the angle ; upper radial from the angle of the

discocellular ; fifth subcostal from upper angle of cell, third

and fourth stalked from before the angle, second close to and

parallel to their stem, the first opposite the first median.

Hind wings: cell not half the length of wing; discocellular

angulated, the lower arm prolonged, oblique; medians and

lower radial as in fore wings. Scaling smooth and sparse,

the wings semitransparent; the general structure weak and

feeble.

Type Ldiusia benepictalis, sp. n.

Idiusia benepictalis, sp. n.

Wings pale gilded yellow, with dark brown markings.

Fore wings with the whole base brown, separated by a narrow

yellowish fascia, not reaching the costa, from a broad bent

fascia, brown like the base, which again is succeeded by a

broad brown squarish blotch, not reaching below the median

vein, excepting a small curved spur along the second median

nervule, and with its edges all concave; between the two

blotches is a small round yellow spot; exterior line thick,

curved, wavy, forming a tridentate sinus over the three

median nervules, followed immediately by a much broader

submarginal fascia, which touches the exterior line below the

costa, on the lower radial and on the first median nervule,

runs into the apex, and throws off a narrow streak just below

the apex and three more in the lower half of the hind margin,

all four running through into the fringe, which otherwise is

wholly yellow; costa from beyond the brown basal area

broadly deep yellow. Hind wings with extreme base and

largish discal spot brown; the two outer lines exactly as in

fore wings. ‘Thorax, face, and abdomen brown; collar and

basal joint of antenne yellowish; palpi brown, with yellow

rings. Underside paler, with only the apical markings on

either wing and the discal blotch of fore wings represented,

the other markings of the upperside merely showing through.

Several males and females from the Khasia Hills.

The insect reminds one strongly of Hyaloplaga pulchralis,

Moore, but the markings are all much thicker; the costa ot

the hind wings is not bulged, as in that species, and both the

shape of the palpi and the neuration are different.

The female, which I have only recently become acquainted

with, is larger than the male, with pale brown rather dull

markings, and is thus a much less striking-looking insect than

the male.

Genus Pacuyarcues, Led.

Pachyarches punctalis, sp. n.

Like Pachyarches imitalis, Guen., but different ; for whereas

imitalis has a dull diffuse grey discal spot, this species has a

fine black one; and while ¢mztalis has at most two or three

small marginal spots below the apex of fore wings, this has

a minute spot at the end of the veins of both wings

throughout.

MISCELLANEOUS.

Contributions to the Embryogeny of Simple Ascidians.

By Antoine Pizon.

SryeraL points in the development of the Simple Ascidians are

still disputed or unknown, especially the origin of the peribranchial

cavity, the relations of the sensory vesicle to the neighbouring parts,

and the existence of an epicardium analogous to that which is found

in the Compound Ascidians. The species which 1 have had at my

disposal for the purpose of studying these different points are

Cynthia morus and Ascidia villosa, Giard.

The earliest phenomena of segmentation are dissimilar in these

two species, and this is due to the fact that Cynthia morus possesses

an enormous quantity of food-yolk, of which we still find a con-

siderable portion in the larva at the moment of hatching.

J.—After the formation of the cavity of the archenteron in Ascidia

villosa, its walls send out two lateral extroflexions which grow

pretty rapidly, while each of them speedily attaches itself to the

ectoderm. ‘The latter layer on its part becomes slightly invaginated

at the two points of contact and then perforated ; the larva hence-

forth exhibits two new apertures, which are added to that of the

stomodeum, and the existence of which was first demonstrated by

Krohn and Kovalewsky. The enteric cavity is gradually enveloped

by the dilatation of its two diverticula, which become the peri-

branchial cavity. ‘The two lateral apertures are thrust more and

more into the median line on the dorsal side in consequence of the

development of the larva; finally they unite and form but a single

orifice, which will be the cloacal aperture of the adult.

Miscellaneous. 107

11.—The heart in Ascidia villosa and Cynthia morus is formed,

as in the Compound Ascidians, by a diverticulum of the enteric

cavity, which becomes isolated at an early period when the peri-

branchial sacs are in process of development. This diverticulum

becomes a little closed sac, a certain portion of the wall of which is

forthwith invaginated, thus producing a double cavity : the inner

one is the cardiac cavity, which communicates by the cleft of

invagination with the hemal spaces ; the outer chamber is the peri-

cardium, which is completely closed and does not contain a drop of

blood ; it represents a portion of the archenteron.

III.—All along the cardiac cleft, and applied to it in the manner

of an obturator, is seen another sac with very delicate epithelial

walls. At the time of the appearance of the first branchial clefts in

Ascidia villosa, this sac still has a wide opening into the enteric

cavity from which it is derived, while its other extremity gradually

elongates and moulds itself round the alimentary tract after the

fashion of a mesentery.

In its origin, disposition, and relations to the heart this sac is

absolutely identical with the epicardium, which hitherto was known

only in the Compound Ascidians.

In Cynthia morus the epicardium appears as two great prolonga-

tions of the peribranchial sacs, and thus recalls with great exactness

the arrangement which I have described in the Botryllide.

The mode of formation of this aperture is precisely as described

long ago by Krohn and Kovalewsky and since observed by all

ascidiologists ; but the point on which I desire to insist is the endo-

dermal origin of the peribranchial cavity. I therefore do not share

the view of Metschnikoff and Kovalewsky, who have maintained

that this cavity is due to two ectodermal invaginations, which

gradually surround the cavity of the enteron, These two learned

naturalists, whose endeavours to study the transparent embryo were

evidently impeded by the egg-membranes, were unable to make out

precisely the earliest processes, and observed only the stage in which

the ectoderm is seen already invaginated. The examination of

larvee of all ages, still enclosed in the peribranchial cavity and cut

into thin sections, is the only method that enables us to decide the

question with accuracy.

It is important to determine the origin of the peribranchial

cavity in Simple Ascidians, on account of the conclusions with

regard to blastogenesis in the Botryllide which have been quite

recently deduced therefrom by a Norwegian ascidiologist named

Hjort*. We know that in Compound Ascidians the branchio-

intestinal cavity of each bud is produced by the proliferation of the

outer peribranchial wall of the parent ascidiozoid, which is of endo-

dermal origin in the larva as well as in the bud, as was shown by

me in a former papery. Hjort, without making a study of the

Botryllid larva, has applied to it, with regard to the origin of the

108 Miscellaneous.

peribranchial sacs, the results obtained by Metschnikoff and Koya- |

lewsky in the case of Simple Ascidians, and has consequently arrived

at the conclusion that the branchio-intestinal cavity is of endodermal

origin in the larvee of Compound Ascidians, while it is a formation of

the ectoderm in their buds.

In this particular case, therefore, I am unable to share Hjort’s

opinion; the larve of Amaroncium Nordmanni and Fragarium

elegans * had already led me to the same results as the Botryllide

and Simple Ascidians, as to the endodermal origin of the peri-

branchial cavity; and herein I am in accord with Della Valle f,

who studied Ascedia mentula.

But if the epicardium is a formation of general occurrence in

Tunicates, it does not possess the property of blastogenesis in all of

them. ‘This property is non-existent in the Simple Ascidians, in

which the epicardium surrounds the alimentary canal and simply

plays the part of peritoneum. In the Botryllide the epicardium

exhibits the same arrangement as in the Simple Ascidians, but the

peribranchial wall, which, after all, is nothing but the foremost

portion of the epicardiac sacs, possesses the property of budding.

Finally, in the Polyclinide (Amaronciwm, Circinalium, &c.), in

Clavellina and Perophora we know that the epicardium is extended

to the tip of the stolon or of the peduncle when it exists, and this

it is that, by dividing or proliferating in different ways according

to the particular group, gives rise to the enteric cavity of the new

buds.

IV.—I have traced, in series of thin sections, the development of

the nervous system of the larva as well as of the fixed Ascidian,

and have succeeded in elucidating various points with reference to

the sensory vesicle, as to which Kuppfer and Kovalewsky were

unable to agree.

The sensory vesicle never opens on the surface of the ectoderm,

as it was stated to do by Kovalewsky ; but at a very early period it

is brought into connexion with the anterior portion of the future

branchial sac by means of a very short tube, which still exists, at

the moment of fixation, in order to give rise to the vibratile organ.

This communication between the nervous vesicle and the branchial

sac is of variable duration in the different species; it no longer

exists in Ascidia villosa at the time of hatching, any more than in

the larve of Amaroncium and Fragarium ; while in Cynthia morus

the communication is still very wide on the second day after

hatching.

The nervous system of the adult is produced by that of the larva

before it commences to degenerate, and by means of a process which

recalls that which I have already described in the case of Fragarium

elegans and Amaroncium Nordmanm t.—Comptes Rendus, t. exxi.

On a new Lamellibranch (Scioberetia australis) commensal with an

Echinoderm. By Féurx. Bernarp.

In studying the collection of Echinoderms made by the Cape-

Horn Expedition in the years 1882-1883 I have had occasion to

examine several specimens of a Spatangid, Tripylus ewcavatus, Phil.,

and I discovered that this sea-urchin is viviparous. But, while the

majority of individuals carry young in process of development in

the depressed ambulacral zones, in two specimens the young were

absent and were replaced by a Lamellibranch, the maximum size of

which does not exceed 3 millimetres. I have been able to study

this animal by the dissection of three examples, and by means of

sections in the case of a fourth: the state of preservation of the

specimens is highly satisfactory.

The shell is entirely contained in the thickness of the mantle; it

does not cover half the breadth of the animal. The mantle, on the

contrary, envelops it completely. It is prolonged in front by a

groove, which recalls the siphon of Gastropods; it is united together

in the median line behind, and leaves only a posterior orifice, in the

centre of a circular area. The shell, which is very thin, equivalve,

and posteriorly truncate, bears radiating striz, and its ventral

margin is slightly plicate. No muscular nor pallial impressions.

In the umbonal region, which is not projecting, the embryonic

shell is seen. The cardinal margins of the two valves are in contact

only along the embryonic shell ; further on they are separated and

connected by a delicate epidermic ligament. The ligament proper

is internal and occupies the whole of the embryonic hinge; on

dissolving it by means of hypochlorite of soda, it is seen that the

hinge has retained exactly the conformation that it possessed in the

embryos, which are met with in abundance with the adults. It

exhibits at its summit a little ligamentary pit interrupting the

cardinal margin, and on each side parallel crenatures similar to

those which exist in the embryos of a multitude of Acephala

(Nucula, Mytilus, Arca, &c.). In the adult the ligament runs out

on to all these structures, and neither cardinal plateau nor teeth,

properly so-called, are formed.

As opposed to this persistence of the embryonic type of shell the

internal organization exhibits an advanced specialization.

The adductor muscles, greatly reduced in size, are seen (in a

section) in their normal position. The foot is but little developed

and is divided into an anterior and a posterior lobe ; in the retracted

condition due to immersion in spirit it displays a deep longitudinal

groove, which manifestly corresponds to acreeping sole. No byssus.

Nervous system normal, with very large ganglia.

Alimentary canal very simple. The mouth opens on the dorsal

face of the visceral mass; on each side it is joined by a deep groove,

bounded by two lips which represent the rudimentary labial palps,

and extend on the sides as far as the base of the gills. Csophagus

straight, dorsal; stomach spacious, with a broad opening from the

digestive gland (liver), which occupies the two anterior thirds of the

1 10 Miscellaneous.

visceral mass and forms in three places the wall of the stomach.

The latter exhibits on the right side a cecum, which appears to

secrete a hyaline style; the posterior intestine runs in a ventral

direction and then towards the dorsal aspect; on issuing from the

visceral mass it traverses the ventricle and terminates in a short

bell-shaped rectum.

Kidneys greatly reduced, and situate at the posterior extremity

of the visceral mass, at its Junction with the mantle. Renal orifices

behind those of the genital organs. Genital gland hermaphrodite,

occupying the posterior third of the visceral mass.

The gills are the most interesting organs. On each side there

exists a single branchial lamella bent round into a dihedron, of

which the anterior ridge is occupied by a blood-vessel. One of the

folds is united by its margin to the mantle and the other to the

visceral mass, and along these lines of junction there runs a vessel

(or sinus); moreover, the two gills are united together by their tips

in the median line at the point where they detach themselves from

the body. In this way there is produced a posterior mantle-cavity,

communicating with the anterior one only by a median orifice

between the visceral mass and the point of junction of the two gills.

This posterior cavity is utilized as a brood-chamber, which appears

to be of a very different nature from that which is found in Lnto-

valva [so far as may be judged from the very brief description of

Voeltzkow *]. Each branchial lamella is formed by a fold con-

tinuous with the mantle ; its anterior surface bears strongly ciliated

thickenings, resembling filaments, parallel to the cardinal margin,

with a hemal canal in their interior. Apertures at regular intervals,

in the shape of a funnel widened posteriorly, traverse the lamella

between the thickenings. It seems natural to regard this organ as

a series of filaments fused together; but towards the tip of the

gill, which appears to be in process of enlargement, we observe that

the lamella becomes hollowed out by apertures, and exhibits fresh

ciliated thickenings, while free filaments are nowhere visible.

The pallial and visceral lamelle are united by transverse

trabeculee.

In a subsequent paper I shall discuss the interpretation that may

be attached to this gill; I shall describe the anatomy of the

embryos, and shall deal with the affinities of the animal, which

seems to me to be allied to the Erycinids, the Galeommids, and to

two forms which are still insufficiently known, Chlamydoconcha,

Dall, and, especially, Hntovalva, Voeltzkow t. Nevertheless the

On a Chilian Example of Pterodela pedicularia, Z., with doubly

abnormal Neuration. By Atrrep Grarp, Professor at the

Sorbonne.

In the numerous consignments which our colleague Mr. F.

Lataste has kindly sent me for the study of Margarodes vitium LI

have found at different times the larva, nymphs, and perfect insects

of a Psocid which is common in Chili on old vine-stocks, especially

at Caillihue and Santa Rita. This is Cwetlius pedicularius, L.,

which Kolbe has made the type of the subgenus Pterodela.

The species is widely distributed in Europe on old wood of various

kinds and even in dwellings, where the imago is seen from the

end of August to about the 15th of October. In Chili the perfect

insect commences to appear about the month of December, and at

this period there still exist many untransformed larvee.

These Chilian examples do not differ from those of the old world.

Their size is perhaps a little less and the pterostigma a little

more cloudy. It seems to me evident that this Psocid has been

introduced into Chili with some vegetable débris, perhaps with the

vines themselves. It is not mentioned in the list of Neuroptera

in C. Gay’s ‘ Histoire Naturelle du Chili.’

By a singular coincidence the first adult example which I received

from Caillihue, a male, presented an abnormal neuration, and ab-

normal in a different manner in each of the two anterior wings,

so that I was some time in recognizing our common Cweilius pedi-

cularius, L., and my doubts only vanished later when M. Latasto

sent me fresh and perfectly normal specimens.

The study of teratological cases in the neuration of insects

presents considerable interest from the point of view of biological

philosophy. It is important not to lose the documents which nature

has furnished us with in so unusual a manner, and for this reason [

have thought it advisable to describe and carefully reproduce the

wings of the abnormal Cweilius of Chili.

If we compare the left wing of the abnormal specimen (fig. 1)

with the left wing of a normal individual (fig. 3), we see that the

second posterior marginal cellule (B) is wanting, the median nervure

sending only one branch to the margin of the wing instead of two.

This is a simplification of the neuration which is only met with in

the normal state in the inferior wing in the Psocids (cf. fig. 4, the

inferior wing of Cecilius pedicularius).

De Sélys Longchamps has described an analogous monstrosity in a

Psocus bipunctatus, Latr., from the Rambur collection. In the

-genus Psocus there are normally four posterior marginal cellules. In

112 Miscellaneous. pe

the abnormal specimen the left superior wing has only three mar-

ginal cellules instead of four, the most basal being absent. ‘The

monstrosity was thus of the same nature and affected the same side

as in our C. pedicularius *. 4

The right wing of our teratological example possesses, indeed, the

second posterior marginal cellule, but it is abnormal from another

point of view. While in the normal condition the branch of the

radial nervure and the median nervure are united over a certain

extent of their course (figs. 1 and 3, A), in the abnormal wing these

two nervures touch at a single point (fig. 2, A), thus realizing a

condition which we find normally in certain Psocids, notably in the

genus Mesopsocus, Kolbe.

De Sélys Longchamps has already pointed out that a similar

character would be insufficient to separate Mesopsocus from Hlip-

socus; certain examples of Hlipsocus unipunctatus, Miill., present,

in fact, a disposition of the nervures which is intermediate between

the type of this § species and Llipsocus laticeps, Kolbe t.

The teratological variations in the reticulation of the wings of

insects appear to be abrupt and in discontinuity with the normal

condition. If they are preserved by heredity they constitute new

varieties, sometimes even new genera or species if other characters

are modified in addition, so as to allow of a more complete differ-

ential diagnosis. Starting from this point, certain naturalists have

maintained that all species have a similar origin, and that the action

of the primary or secondary factors of evolution, Lamarkism and

Darwinism, should give place to this new conception of the descent

of living beings by discontinuous teratological modifications.

This, we think, is an inexact and exaggerated interpretation of

facts which in themselves are highly important. The production

of species by a discontinuous process remains a particular case whose

importance may have been undervalued, but on which it is not

advisable to found a general law.

In reality the different’ types of neuration represent so many

stable states of equilibrium between which no continuous gradual

passages can be established. The forms intermediate to these states

of equilibrium are not realized, because they do not correspond to

conditions of sufficient stability. To make use of a trivial com-

parison, one cannot show the half or any fraction whatever of one step

of the ladder. In similar cases the progress is very discon-

tinuous or, what comes to the same thing, only manifests itself in a

discontinuous manner. But we cannot derive from these facts any

argument against the formation of species by natural selection, still

less can we find there the sole and complete solution of the com-

plex problems of metamorphism.—Actes de la Société Scientifique

XIV.— Considerations on the Surviving Refugees in Austral

Lands of Ancient Antarctic Life. By C. Heptey, F.L.S.,

Assistant in Zoology to the Australian Museum *.

To ordinary readers the most desolate region imaginable is

that within the Arctic Circle. Yet the intrepid explorers who

have furthest penetrated into the northern wilds encountered

there bears, wolves, musk-oxen, walrus, seals, and other

mammals, and saw flocks of birds steering northwards beyond

the utmost limit of discovery.

Infinitely more desolate is the mysterious and perhaps im-

penetrable Antarctic continent or archipelago. For aught we

know, here may tower loftier mountains than geographers

have marked in the Himalayas. From the ship’s deck

voyagers | have descried volcanic peaks trending into an

interior which extends as an unbroken sheet of ice and snow.

Beyond the beach its whole surface hardly now nourishes a

single animal or plant; for the lichen reported by Borch-

grevink { from Possession Island and Cape Adare alone

constitutes the recorded terrestrial flora. Enveloped in an

atmosphere of universal death, wrapped in its closely clinging

cerements of ice and snow, the one expression of the

Antarctica of to-day is that of lifeless silence *.

But it was once otherwise. Not only may a naturalist

assert that here stately forests once stood, streams once rippled,

and green fields smiled, but he can picture what trees com-

posed those forests, of what kind were the frogs and snails

they sheltered, and of what form were the fish that swam in

those streams.

Early scientific travellers | remarked that the converging

continental masses of the southern world held as common

stock certain forms of life. Closer enquiry elicited that these

common forms were primitive, often isolated types, survivors

of some ancient population overwhelmed and slaughtered by

invaders from the north. South Africa was found to stand

somewhat apart from the closer bond which united Tasmania

and Australia to New Zealand and South America, while New

Zealand is in turn poorer actually, if not comparatively, than

Tasmania in South American affinities.

“Community of type,” writes Dr. Gill}, “must be the

expression of community of origin .... and recent palzon-

tological finds indicate that even the Thylacinids (or, at least,

forms resembling them) were formerly natives of southern

America... .% The freshwater fishes [of New Zealand] must

have been derived from the same common source as those of

the isothermal portions of Australia (of course including Tas-

mania) and southern America. There may not have been a

continuity of land at any one time between South America,

Australia, and New Zealand, but at some remote period in the

past itis at least possible that there was a region in which

Galaxids and Haplochitonids were developed, and subse-

quently representatives of those families might have found

their way into the regions where they now abound.”

An enumeration of the genera common to South America,

New Zealand, and Tasmania, and therefore probably of

Antarctic origin, would exceed the limits of this paper.

Forbes § quotes numerous instances; and for more ex-

haustive data monographs of most groups of animals and

plants of these countries may be consulted *.

We may compare the shattered biological monuments of

Tasmania and South America to the broken columns found by

Oriental travellers in the ruined and deserted cities of a

vanished civilization; and as an archeologist may restore

from such fragments the fallen temples or disused aqueducts,

so may a naturalist trace the missing arches of life that once

spanned the gap. Some of the efforts to do so may be here

reviewed.

Prof. Hutton has conjectured ¢ that such a bridge spanned

the South Pacific from Chili to Samoa, and thence to New

Zealand. Claiming South-American relations for the New-

Zealand fauna and flora, he accounts for their entry into New

Zealand by this assumed bridge. Against Prof. Hutton’s

arguments it may be urged that, though the relation of New

Zealand to South America is indisputable, it is less than

between the latter and Tasmania, and that the demand for a

former union may be satisfied by supposing an approach but

not a connexion with Antarctica. ‘The sole supports of the

theoretical transpacific bridge are the difficulties it is believed

to explain. <A biologist might object that, had such a bridge

existed, New Zealand being at the furthest extremity, ought to

contain fewer South-American affinities than do intermediate

Polynesian islands, like Samoa or Tahiti, lying nearer to the

source. Qn the contrary, these islands are devoid of such.

And a geologist might say that this supposed bridge was

discordant with the main orographic structure of the region.

116 Mr. C. Hedley on Surviving Refugees

Tts relics are detected by Prof. Hutton in an abyssal area two

thousand fathoms deep, which only in strained language can

be termed a “plateau.” Of where he supposes that it lay

Geikie * writes: ‘so abruptly does the continental plateau

rise from the ocean trough, that a depression of the sea-level

or an elevation of the plateau for ten thousand feet would add

only a narrow belt to the Pacifie coast between Alaska and

Cape Horn.” Much of the biological and geological data on

which Prof. Hutton’s paper was based have since been refuted

or withdrawn.

Another answer to the question at issue is tendered by

Dr. H. O. Forbes t. After a lucid summary of the kinship

of austral life observed by earlier naturalists and of facts

collected by himself in the Chatham Islands, he constructs

an immense hypothetical Antarctic continent to explain these

problems.

The impression left on my mind by a careful study of this

paper is that a foundation so slender is insufficient to bear a

superstructure so vast. No geological era is assigned for the

map of Ancient Antarctica accompanying the article. ‘To

this area the Mascarene Islands appear to be attached chiefly

upon the strength of an extinct bird of dubious lineage. The

difficulties of the change from the climate of primeval Ant-

arctica and the change in the depth of circumpolar seas are

not explained, or, indeed, the changes proved. The Ant-

arctic fauna and flora, so far as surviving fragments allow us

to reconstruct them, do not suggest that wealth of forms

which so wide an extent of land should have developed. A

much harsher climate would have prevailed over Forbes’s

broad continental area than over a chain of islands or a narrow

strip of land. Had the conditions indicated by Dr. Forbes

once existed, then each of the southern land-masses should have

preserved an equal heritage of Antarctic life, which is not the

case. A sharing of population may not be invariably cited

(as it is in this paper) as indicative of former land-passages,

for it has been clearly demonstrated in the case of the Azores

and Galapagos that considerable immigration may occur

across wide expanses of ocean.

Mr. H. A. Pilsbry has remarked { that “the presence of

very similar forms in southern South America and Tasmania

and New Zealand has been accounted for by the hypothesis

ot a former more extensive Austral continent or ‘ Ant-

arctica,’ which may have been supplied with these snails, as

well as with certain marsupials, fishes, &c. from Australia,

and subsequently became united at Cape Horn, transferring

the fauna. The connexion could hardly have been in reverse

order, or why should not Kdentates and Hystricomorph

Rodents have invaded Australia?”

The opposite view, viz. that Antarctica transferred a fauna

from America to Australia, is favoured by the facts that the

fossil marsupials from the Patogonian Eocene antedate * any

fossil marsupials recorded from Australia, that the marsupi-

alia dawn upon the Australian horizon as a highly differen-

tiated group, and that Prof. Spencer has demonstrated T “ that

the diprotodonts had their origin in the Kuronotian region,”

meaning that their centre of dispersal lay to the south-east of

Australia. Von Ihering has suggested { that a large area of

South America was separated in Mesozoic times from the

remainder, and maintained a distinct fauna and flora. If

from this tract, which he terms Archiplata, were excluded, as

he holds, placental mammals, it may have peopled Australia

with marsupials, and yet not have transferred thence Eden-

tates or Hystricomorph Rodents.

The relation of Antarctica to African lands is a subject on

which an Australian student has little chance to form an

opinion. Perhaps the faint though real affinity (as shown in

the distribution of the mollusks Endodontide, Rhytidide,

and Acavine) would be explicable on the supposition that

before either America or Australia had united with Antarctica,

* This statement is derived from the following data, for which I am

chiefly indebted to the kindness of my friend Mr. W.S. Dun, Assistant

Palzeontologist to the Geological Survey of N. 8. W., himself the author

_of important papers on the subject. The oldest DESCRIBED Australian

mammalia are Pliocene, viz. Ornithorhynchus maximus, Dun, and Echidna

colony. From Victoria Prof. M‘Coy has claimed as Pliocene (‘ Prodro-

discussed till they have been studied, described, and named. Yet on

@ priort grounds the Diprotodontia can scarcely be supposed to have so

far proceeded on the path of differentiation from the radical Polyproto-

dont stock as to have evolved into Halmaturus at the early date of the

Kocene ; further, the sea-shells of this deposit form an incongruous

environment for a wallaby. For a list of the numerous marsupials ex-

tracted from the Upper Kocene beds of Santa Cruz, South America, see

118 Mr. C. Hedley on Surviving Refugees

Africa had already been joined to and broken from it,

receiving a colony thence or leaving one there to mix with

American and Australian forms when the vicissitudes of

continental growth permitted.

In an inquiry * into the distribution of the pond-snail,

Gundlachia, 1 lately proposed, as the simplest solution of the

problem, that DURING THE MESOZOIC OR OLDER TERTIARY, A

STRIP OF LAND WITH A MILD CLIMATE EXTENDED ACROSS THE

SourH PoLe FROM TASMANIA TO TIERRA DEL FUEGO, AND

THAT TERTIARY NEW ZEALAND THEN REACHED SUFFICIENTLY

NEAR TO THIS ANTARCTIC LAND, WITHOUT JOINING IT, TO

RECEIVE BY FLIGHT OR DRIFT MANY PLANTS AND ANIMALS, as

the Galapagos received their population from America or the

Azores theirs from Europe.

This conclusion was built upon the following evidence. A

minimum of land-extension compared with that asked for by

Hutton or Forbes was demanded. A milder climate is ad-

mitted by geologists, even by those who dispute its cause, to

have formerly prevailed in Arctic regions: a mild Antarctic

climate should therefore be admissible. Dr. Murray remarks ¢

of the fossils collected by Capt. Jensen close to the Antarctic

Circle that they “are probably of a Lower Tertiary age, and

they indicate a warmer temperature than now prevails in these

high southern latitudes.” A cursory survey of a collection

of Eocene Mollusca from the Muddy Creek beds of Victoria

suggests to me that warmer seas then prevailed. Its wealth

of Cyprea and Voluta points to a tropical climate. I observe

there tubes of Kuphus, a genus now ranging from Sumatra to

the Solomons, whose evidence is corroborated by extinct

allies of Nautilus. That New Zealand once extended very

far south of its present position to or, perhaps, beyond the

Macquarie Islands, is granted by all who have investigated

the subject . Possibly this southward extension was syn-

chronous with the northward extension indicated § by the

range of Placostylus. "That this southward extension ot New

Zealand did not, during the marsupial exodus, actually touch

the highway between Tasmania and South America, I infer

from the fact that such passengers as the venomous snakes,

extinct Palimnarchus, cystignathous frogs, monotremes, and

marsupials failed to arrive in New Zealand. ‘The southward

prolongation of Tasmania in the direction of Royal Company

Island is suggested by the Tasmanian axes described * by

Prof. David.

The evidence collected tends to show Antarctica as an

unstable area, at one time dissolving into an archipelago, at

another resolving itself into a continent.

How this would affect the marine shallow-water fauna has

not been previously considered. Under the circumstances [

have described, the South Pacific would stretch within a few

degrees of the Pole into a deep bight or gulf extending from

Tasmania to Cape Horn. Into the western extremity would

open the long and narrow tongue of what is now the Tasman

Sea. When the climate cooled, the fauna at the head of this

Antarctic Gulf, as I propose to call it, would be driven north-

wards to milder zones. By diverging meridians a similar

fauna would reach New Zealand, New South Wales, and

Chilif. Ina precisely similar manner Darwin { has showa

how the northern Glacial period drove the same Polar flora

by radiating paths to the Alps, Himalayas, and Alleghanies,

where they now survive stranded on mountain-tops.

If, when this northward migration occurred, continuous land

had reached from Australia to Chili, then none of the fauna

of the Antarctic Gulf could have entered either the Indian or

the South Atlantic Oceans. We have, however, no warrant

for believing that the Antarctic bridge long endured as con-

tinuous and contemporaneous land; and that it was pierced

by channels is proved by the escape of stray members of that

characteristically Antarctic genus Struthiolaria to Patagonian

coasts (S. ornata, Sowerby §), on the one hand, and to Ker-

guelen (S. mirabilis, Smith) || on the other.

The destruction 4 which the ancient fauna of the Antarctic

Gulf has endured, and the length of time which has elapsed

since its expulsion, deprives us of much hope of reconstructing

it. Since that event, for instance, the genus Haliotis has

probably altogether grown up as a characteristic feature of

XV.—The Male of Apus cancriformis. By W. BLAXLAND

BrenuaM, D.Sc. (Lond.), Hon. M.A. (Oxon.), Aldrichian

Demonstrator in Comparative Anatomy, Oxford.

In view of the rarity of the male individuals of this interesting

Phyllopodan Crustacean, it may be worth putting on record

the occurrence of one amongst the specimens of Apus used

for examination in the ordinary course of our work in the

Zoological Laboratory here in Oxford. The specimens were

obtained through Fric, of Prague, from Podébrady, a town

on the Elbe.

Apus is one of the stock examples of parthenogenesis, the

bulk of the individuals being females; that males do occur

occasionally we know from the observations of Kozubowski,

von Siebold, and others; but locality and season appear to

have considerable influence on their occurrence. ‘Thus, in

1858, out of 549 specimens of Apus collected at Krakau, as

many as 154 were males, whereas in 1866 out of 999 col-

lected at Breslau there were only 7 males. Von Siebold’s

repeated endeavours during several successive years to obtain

males are matters of history.

The credit of first describing the male is due to Prof. Kozu-

bowski, who, in 1857, gave an account of the testis, sperm-

duct, and spermatozoa (Arch. f. Nat. xxiii.), and laid the

foundation for the view which has since then been nearly

universally adopted, viz. that Apus is parthenogenetic. Up

to that period it had been considered hermaphrodite.

It will not be amiss to note that the only external point of

difference between the two sexes is the absence in the male

of that modification of the sixteenth appendage which results

in the female in the formation of an egg-pouch (‘‘ oostego-

pod”); in fact, the sixteenth appendage of the male is

precisely like its neighbours, and at its base the sperm-duct

opens.

I looked carefully for any appendages which might be

* Proc. Roy. Soc. Vict. 1894, p. 197.

Male of Apus caneriformis. 121

modified for holding the female, such as occur in its ally

Branchipus; but none exist.

It is usually stated, on Kozubowski’s authority, that the

male is about one third shorter than the female, with a dis-

tinctly narrower abdomen and flatter carapace. These state-

ments can scarcely be said to be true in the present instance.

The male did not differ noticeably in size from the rest of the

specimens, some of which were slightly larger, others smaller.

I measured one female, taken at random, and found the trunk

(excluding the head, that is) to be 36 millim. long; the

trunk of the male is 33 millim.; the diameter of the female

abdomen, close to the last appendage, is 5 millim., that of

the male 4 millim.

Sir John Lubbock has recorded (1863) that the males of

another species, Lepidurus productus, are larger than the

female. We cannot, then, make any general statement as to

proportionate size of the two sexes.

On referring to Mr. Bernard’s little book, ‘ The Apodide,’

I was rather surprised to find that no mention of the anatomy

of the male Apus occurs in the body of the book; but in the

appendix he quotes his letter to ‘ Nature,’ vol. xlin. p. 843,

in which he gave a brief history of the observations on the

male. The name of Kozubowski does not appear in his list

of references, nor that of von Siebold. Seeing that Bernard’s

book is the only recent English account of the anatomy of

Apus, it is regrettable that space was not found for a reference

to the sexual difference. But no doubt a description of the

mere anatomy of the animal was not so much his aim as a

comparison of Apus with an Annelid. Moreover, he wished

to emphasize the hermaphrodite nature of Apus.

Now it is more than four years since Mr. Bernard an-

nounced, in a brief note published in the ‘ Jena. Zeitsch.,’ the

discovery of the existence of testes, or, at any rate, of “ sperm-

producing centres,” in the female Lepidurus; but beyond

stating that he has observed the same state of things in some

other species, and has seen spermatozoa in the lower part of

the duct, he has not materially added to this bare statement

either in his book or elsewhere. I think it is not an exag-

geration to say that zoologists have been impatiently waiting

for a detailed and dlustrated account of this phenomenon.

Apus has for so many years been regarded as_partheno-

genetic, that naturalists hesitate to accept the bald statement

that it is “ hermaphrodite and self-fertilizing.”

On p. 809 of his book Mr. Bernard writes :—‘‘ The sperm-

producing centres were found scattered here and there among

the rich branches of the segmental diverticula of the genital

122 Mr. W. F. Kirby on Two new

tubes. They occur either at the tips of such branches where

the eggs ordinarily develop, or as slight lateral bulgings of

thesame.” I have recently had occasion in the course of my

work to examine a series of longitudinal sections through

Apus caneriformis, and I have failed to identify any such

** sperm-producing centres.””

On p. 144 he gives a figure representing a portion of the

ovary, and at one point the epithelium of the duct is inter-

rupted by a group of small round granules, which is labelled

‘testis, as occasionally found (e. g. in Apus cancriformis).”

This “ testis” is neither a terminal nor a lateral bulging ;

this figure, too, which is the only illustration of the point in

question, is so crude that we ought to have further details of

these ‘‘ sperm-producing centres.”

I will not presume to deny the possibility of hermaphro-

ditism in the Apodide, however improbable it may be; I

merely repeat, we wait for further evidence.

With regard to Bernard’s figure of the ovary I would say one

more word. Von Siebold, in a paper accompanied by beautiful

figures, showed that each terminal swelling of the ovary is

formed of four cells, of which the distal cell becomes the egg-

cell, the other three being yolk-forming cells. That this is

true for Apus a glance at a section is sufficient to demon-

strate; but Bernard, in the figure referred to (illustrating

presumably Lepidurus), represents the proximal cell of the

four as the egg-cell. If this is really the case, we have an

extremely interesting difference between the two genera.

XVI.— Descriptions of Two new Species of Kugaster (Hetro-

dide) from Kast Africa. By W. F. Kirsy, F.L.S., F.E.S.,

&c., Assistant in Zoological Department, British Museum.

Eugaster suakimensis.

Long. corp. 87-40 millim.

Head brown, strongly punctured above, the lower mouth-

parts, the palpi, and the base of the antenne more or less

varied with testaceous; a short conical testaceous spine

between the antennz ; pronotum reddish brown or blackish,

varied with testaceous in front and along the median line, and

with reddish behind. It is strongly rugose, with two irre-

gular longitudinal elevations on each side of the median line ;

front edge with a row of 4 black spines, placed at about

equal distances apart; between these are two shorter ones

between the middle ones in the males only, and another be-

tween the two outer ones on the right-hand side only in both

sexes. ‘The outer spines are at the front angles of the front

lobe of the pronotum, and behind and above them are much

larger spines at the hinder angles of front lobe. There is also a

strong black spine on each side of the middle lobe of the pro-

notum. ‘The hinder ridge of the pronotum bears a row of 6 or

7 black spines on each side, increasing in size towards the front.

Legs brown, the coxe and tarsi slightly varied with testa-

ceous or reddish; front cox spined; all the tibiae with a

double row of short partly testaceous spines, least numerous

on the middle tibiz. Abdomen brown, dotted with testa-

ceous, and inclining to testaceous towards the ends of the

segments; the base, sides, and under surface more or less

testaceous, especially in the males, and dotted with black.

Described from four specimens, two of each sex.

Allied to £. spinulosus, Linn., and H. Woodti, Kirb., but

Eugaster frater.

Long. corp. 33-35 millim.

Male.—Closely allied to the last species, but the head and

pronotum are more uniformly dark. The front is less con-

vex, the antennze are testaceous, and the face and palpi are

much varied with reddish. ‘lhe cox and legs are testa-

ceous, longitudinally striped with brown; and in the lightest

specimen the hinder halt of the pronotum and the base of the

abdomen beneath incline towards testaceous, but there are no

testaceous markings on the sides of the abdomen. On the

front of the pronotum there are two spines at the angles, and

two central spines, widely separated, but no intermediate

ones; the middle lobe of the pronotum has a large spine on

each side, and between them are two slight humps, behind

which are two more elevations, forming short upright spines.

The row of 14 large spines running round the hinder edge of

the pronotum is regularly arranged and more or less testa-

ceous.

hope that the above short description will be sufficient for the

identification of the species.

A single female specimen of Prionocnemis verruciferus,

Karsch, or of a closely allied species, was received from

Mombasa at the same time as the specimens of Hugaster

frater. Karsch’s species was described from a single male

specimen, and although the sexes of the Hetrodide differ

little, I await further specimens before describing an insect

which does not quite agree with his description, but which

is of a different sex.

As the genus Pritonocnemis, Karsch, is preoccupied, I

propose to rename it Madiga.

The Hetrodidz appear to be very numerous in Africa, and

no doubt many species still remain to be discovered.

Sharpe.

3. This new species differs from M. Jackson? in having

. the fore wing nearly entirely black, the veins of the discoidal

cell marked with white ; while on the discal portion of the wing

between each of the median nervules is a hastate mark, which

combined forms a white patch in the middle of the wing.

Hind wing. Primrose-yellow, with a heavy black costal

border commencing from the first subcostal nervule and ex-

tending below the discoidal nervule.

The third median nervule is indicated by a black spot at

the end. The other nervules are marked by very minute

black spots near the hind margin. The base of the wing

has a black shading, rather stronger than in M. Jackson.

Underside, White on the fore wing, the apical portion

being suffused with primrose-yellow, with a little orange on

‘the costa at the base of the wing.

126 Miss E. M. Sharpe on new .

There are no black spots marking the end of the nervules

as in M. Jacksoni.

9. Very similar to the male, the white on the fore wing

being less distinct and the hastate markings not so sharply

defined.

Hind wing. Primrose-yellow, the black costal border being

indicated by two black spots on the first and second median

nervules. Two minute black spots at the margin mark the

first and second median nervules.

The underside differs in the yellow on the hind wing being

rather deeper in colour, with three minute. black spots on the

submedian nervure, the first and second median nervules, and

a fourth spot on the first subcostal nervure.

Expanse, ¢ 1°9, 2 2:2 inches.

Family Lycenida.

Alena picata, sp. n.

Fore wing. Black, relieved by a white transverse band

nearly oval in shape from the costal margin, across the

discocellular nervules, and extending to the second median

nervule; about the middle of the inner margin is a second

white mark extending to the first median nervule; these two

white marks are distinctly separated by the black of the

centre of the wing. The inner marginal white mark is co-

terminous with the broad white band of the hind wing.

Hind wing. Hasa broad marginal border of black followed

by a white band from the costa to the inner margin; the base

of the wing black suffused with orange.

Underside much variegated. Fore wing black, with white

and yellow markings; costa white, with two white spots in

the discoidal cell, the end of the cell being marked with the

white oval spot mentioned on the upperside. A submarginal

row of large spots varying very much in size; these are

tinged with yellow and are divided by the nervules; between

these and the large oval discoidal spot is a second row of

smaller spots, from the costal margin to the second discoidal

nervule.

Hind wing white, with a black mark at the base and a

small white spot in its centre.

Fringe of wing white; a submarginal border of black,

preceded by a broad white band, across which the nervules

Family Nymphalide.

Kallima Jacksoni, sp. n.

Nearest to K. rumia, Boisd.

Fore wing. The whole of the basal area bright violaceous

blue, extending along the inner margin, but not quite to the

external angle. This lighter blue area is bordered by a

broad band of rich cobalt-blue, which separates the violet-

blue base from the brown outer border; this darker blue

colour decreases in size to the first median nervule, where it

terminates. There are six white spots in pairs between each

median nervule, three distinct ones mark the discal area of

the wing, and three (more faintly indicated) are in the

chestnut-brown external border; a white crescent-shaped

mark is situated where the fourth and fifth subcostal nervules

branch out.

A marginal border of chestnut-brown, rather more sombre

in colour near the apex, has a narrow transverse black line

to the third white spot of the outer series above the third

median nervule.

Hind wing. Basal area violaceous blue, with a broad

border of deep chestnut-brown; in this border is a distinct

submarginal line of black, from the costal margin to the sub-

median nervure. On the discal portion from below the first

median nervule are four minute black spots, giving the

appearance of a second thin band.

The anal angle is greyish, extending up the submedian

nervure to the base, the inner margin light brown.

Underside. Brown, like a faded leaf, with a dark trans-

verse line of brown, and a second dark line outlining the

discoidal cell and traversing both wings.

The discal spots on the tore wing are transparent, the first

being ocellated. The ground-colour is sprinkled with

greyish marks and indistinct wavy lines of darker brown.

Two forms of this species, both smaller than the type or

the variety pluto, are in the present collection from Tonkin.

In the first (var. funerea) the shell is of an almost uniform

purplish-black tint, redder towards the apex, the suture being

sometimes indistinctly margined with yellow. The peristome

is yellowish and a former lip is also visible at a considerable

distance from the aperture. The body-whorl is not quite so

inflated below the keel as in the var. pluto or the type. The

largest specimen is 53 millim. in its greatest diameter, and

appears to be adult.

The second variety (var. pallidior), of about the same size,

is yellowish or olive-yellow, with a broad brownish-black

band below the periphery and distinctly visible within the

aperture. In both these varieties the umbilicus is rather

narrower than in the typical form from Siam or the var.

pluto from Camboja. If the form pluto, an intermediate link,

were unknown, the two present varieties would probably be

regarded as constituting a distinct species.

Some specimens from Vanbu, Tonkin (var. tonkdnensis),

differ from both the type and variety (var. flava) described by

Pfeiffer. In form they are a little more ventricose, and they

also differ in coloration. The general ground-tint is purplish

red, interrupted at the periphery by a rather broad yellowish

zone, the middle of which is traversed by a deep red line

varying in width from 2 to 4 millimetres. The aperture and

peristome are livid or lilac, but the columellar callus in the

centre of the base is white and entirely conceals the um-

bilicus. Near the latter there is a distinct inflation of the

surface, a feature less marked in the original specimen

described by Pfeiffer,

Camena vanbuensis.

the sharp carination at the periphery, however, at once

distinguish this form, which, until the connecting-links are

That such links will eventually be found is very probable, in

which case the specific name here suggested may be used in

a varietal sense.

Instances in which keeled varieties of species with a

normally rounded body-whorl occur might be mentioned ;

but I doubt if such an extreme case as the present could be

shown.

Type Charitoprepes lubricosa, sp. n.

It is dangerous to erect a new genus on a female type ; but

the insect appears so entirely different from anything hitherto

described, that I venture to think the male will confirm the

justice of the view I have taken.

brown reticulation and suffusion, with a slight olive tint ;

costa spotted with white and dark brown; a faint darker

oblique line or shade is visible on inner margin at one fourth,

not reaching costa; marginal area suffused with dark brown

brown ; apex of palpi and centre of face whitish. Underside

of both wings whitish, reticulated only with brown; legs

white, mottled with brown.

At first sight the insect reminds one somewhat of certain

species of Thyridide. The length of the antenne and the

unusual character of the ornamentation will easily distinguish

it. It does not appear to be nearly related to any known

species.

and the whole hind margin broadly fuscous; costa bright

yellow; near the base are two broad brown spots, the

beginnings of two lines, which are angulated on subcostal, and

broadening out unite in forming the fuscous basal area; a

third brown spot about the middle of costa gives rise to the

first line, which runs obliquely inwards to inner margin at

one third; it is followed in the cell by a roundish hyaline

scaleless impression, which is in turn followed by a yellow

brown-edged discocellular marking, above which is a small

brown spot on costa, and beyond this a brown semiannulus ;

the fuscous margin is bounded inwardly by the exterior line,

which runs parallel to hind margin, forms a slight but distinct

Fore wings pale straw-colour, almost wholly suffused with

purplish fuscous, the only parts unsuffused being the costa on

either side of the exterior line, a small patch above anal

angle on hind margin, and a squarish space in the cell

between the two stigmata, and that is whitish and semitrans-

parent; along the inner margin, especially between the two

lines, the suffusion is more sparse; first line at one fourth

sinuous, dark fuscous ; exterior line at five sixths, starting

from dark costal spot, wavy and parallel to hind margin for

one third, then forming a rounded sinus, running in along

the first median, thickened below the discocellular and waved

to the inner margin ; first discal stigma roundish, flattened,

just beyond first line; second oblong, flattened, beyond the

discocellular; both dark-edged ; fringes dark fuscous in the

One female from the Khasia Hills.

Thysanodesma ? rosea, sp. n.

@. Wings canary-yellow, with rosy markings ; fore wings

with the costa dotted with black-brown; a brownish blotch

at base of costa and the two stigmata brown, both very large

for the size of the wing, the first oblong, the second quadrate,

the two together occupying the whole of the cell; lines rosy,

first at one third, indistinct, vertical; second near hind

margin, slightly bent just beneath costa, then straight to the

first median, where it touches a broad rosy submarginal band,

then bends inwards and upwards, touching the lower parts of

both stigmata, and reaches the inner margin in the middle;

between it and the inner line below the stigmata is another

rosy line, which seems partially to run round the inner stigma ;

fringe yellow, preceded by a broad rosy band. Hind wings

yellow ; the basal half irregularly suffused with rosy ; the

second line sharply angulated in the middle of the hind

margin, where it touches the rosy submarginal band, and

In the absence of the male its proper place is dubious ; the

labial palpi are long and sharply rostriform, the maxillary

palpi also long; the antenne thick, lamellate, slightly

pubescent beneath.

Genus DiaTHRAuSTA, Led.

Diathrausta profundalis, Led.

In the typical form, as depicted in Lederer’s figure of this

insect, the white costal blotch of the fore wings is well

marked and has a blunt apex ; the white spots in the fringe,

two in the fore wings, and one in the hind wings are pure white

and run in quite up to the hind margin, totally obliterating

the dark dividing line of the fringes. In the Khasias there

occur two forms which differ considerably from the typical

one above noticed. In the first, which I propose to call var.

conicalis, the ground-colour is not so black, more brownish ;

the costal white blotch is thinner and ends in a point, and the

pale blotches in the fringe are not pure white and do not

obliterate the dividing line, but only interrupt it; besides,

both wings are narrower and smaller. In the other, to which

the name obliterata may be given, and which is still smaller

and as dark as the type form, the costal spot is reduced to a

small white patch, and the fringes are dark throughout,

besides which, in the hind wings the exterior line, which,

both in the type form and in conicalis, is evidently twice

bent, in this species runs much nearer the hind margin and

nearly parallel to it all the way.

Genus DipLoryLa, Meyr.

Diplotyla ? albilunata, sp. n.

Fore wings deep velvety blackish fuscous; first line at one

third, thick, blackish, preceded by a pale fascia, which is

distinct and yellow only on the costa; second line before two

thirds, parallel to first, but slightly curved outwards in middle,

followed by a yellow fascia, which is broadest on costa;

space between lines velvety black, except costa, which is deep

yellow, and semilunar spot beyond discocellular, which is

white and semihyaline; fringe concolorous, but white at anal

"angle. Hind wings like fore wings, but without first line ;

the hyaline cell-spot narrower and exterior line straighter ;

fringe white at apex as well as at anal angle. Head, thorax,

and abdomen dark fuscous, the latter slenderly ringed with

yellow and yellowish at apex; palpi and tongue yellowish.

cell filled up with deeper brown, with a small yellow spot in

the middle and two deep brown longitudinal streaks beneath

it along the submedian fold and vein; costa from first line

narrowly yellow, ending in a large triangular costal spot at

two thirds, the apex of which is bent outwards; this blotch

is bounded by the sinuous exterior line, beyond which .a

small additional yellow costal spot is seen. Iringe fuscous,

pale at anal angle. Hind wings and fringes fuscous, the

fringe paler before the anal angle. Head, thorax, and abdo-

men dark fuscous. Underside paler, duller; the hind wings

with traces of paler markings.

pale; a large white semitransparent spot beyond the disco-

cellular, a smaller round one before it in the cell, and a very

minute one before the first line; first line indistinctly pale,

outwardly oblique near base; second line starts as a white

costal spot at three fourths, forms a wavy vertical line from

the subcostal to the first median, with a slight indentation

opposite the cell, runs inwards along the first median till

beneath the discocellular, then obliquely sinuous to inner

margin; fringes concolorous. Hind wings the same; the

exterior line forms a very deep angulation, producing a pale

line from anal angle to near middle of wing (which unites

with the pale edge of the dark discal spot), and a pale blotch

near middle of hind margin; fringes slightly paler. Head,

thorax, and abdomen concolorous; abdomen of male with a

to the lower radial, curving outwards, finely denticulate over

the median nervures, then running in basewards, and finishing

as a wavy line beneath the discal spot, which is distinct,

blackish ; marginal area suffused with fuscous, the median

and basal areas more dusted with it; fringe paler stone-

colour, with two indistinct darker lines, and a black line at

base, preceded by a narrow patch of pale ground-colour.

are broadly truncate at their ends.) Fore legs with tibia and

first joint of tarsus, which is greatly enlarged, hairy, the tibia

with a tuft of long hairs from the base; other legs slender,

the hind tibiz with four slender spurs. Anal segment with

a very large expansible tuft from beneath base of claspers,

which are themselves greatly enlarged and ear-shaped.

this second ocellus is a costal half-ring, followed by a smaller

one, and some black subapical markings ; second line at two

thirds forms an irregularly waved sinus outwards, then is

curved inwards to beneath the discocellular, and ends on inner

margin nearly in middle; hind marginal area, except just

beyond this line, suffused with fuscous ; a row of small black

This species is very decidedly paler, more ochreous, than

admixtalis, Wik. There are in the British Museum collection

four specimens from North-west India placed under admiztalis

so much distorted and damaged that it is difficult to say what

their original position and direction was.

whitish for two thirds; like fore wings in the marginal area,

beyond a curved, slightly wavy, subterminal line. In the

female the fore wings are shorter, slightly tinged with

ochreous; the exterior line is distinct, being edged with

paler, and forming a slight sinus outward in the middle, and

the discal dot is preceded by an indistinct vertical darker

shade; the hind wings are paler, with discal dot and sub-

XXI.—A Revision of the British Jurassic Bryozoa.—Part IV.

The Genera Reptomultisparsa and Diastopora. By J. W.

Grecory, D.Sc., F.G.S.

[Continued from p. 48. }

Family Tubuliporide (concluded).

Genus REPTOMULTISPARSA, d’Orbigny, 1852.

Diagnosis.—Tubuliporide in which the zoarium is en-

crusting and consists of thick multilamellar sheets. The

zocecia are cylindrical and parallel to the surface upon which

the zoarium has grown. ‘The peristome is flush or slightly

raised.

Type species: R. microstoma (Mich.), syn. R. diluviana,

Edw. & Mich. (non Lamx.).

A ffinities.—This genus was founded by d’Orbigny for thick

multilamellar species allied to Berentcea. The division seems

tome convenient. ‘The first of the five species referred to the

genus by d’Orbigny, which is accordingly here taken as the

type, is the Diastopora diluviana, Edw. & Mich. (non Lamx.).

This, however, I regard as the same as Michelin’s Diastopora

microstoma.

Diagnosis.—Zoarium in large, thick, irregular encrusting

sheets, which in the adult completely bury the shell they

encrust. Young forms are flabelliform.

Zoecia long or medium in length. Young zocecia are seen

throughout. The more adult peripheral zocecia are crowded,

and thus not wholly seen. Surface traversed by sinuous

raised ridges.

Peristomes slightly raised, irregularly distributed.

152 Dr. J. W. Gregory—A Revision

Genus Diastorora, Lamouroux, 1821 (emended).

Diagnosis.—Tubuliporide in which the zoarium is erect

and foliaceous. (The zoarium consists of simple fronds or

may be split up into multifid segments, or may grow in hemi-

spherical masses by the crumpling of the fronds, or may be

cylindrical, or may be reteporiform.) The zoarium is uni-

laminate or bilaminate. The zocecia are tubular. The peri-

stomes are flush or raised only a small proportion of the length

of the zocecia. The ocecia are closed, slightly enlarged zocecia.

156 Rev. T. R. R. Stebbing on the

XXII.—On the Isopod Genus Leptochelia.

By the Rev. Tuomas R. R. Sressine, M.A., F.L.S.

WHILE recently exploring Dana’s great Atlas of Crustacea

for certain objects, I found my attention arrested in passing

by the figures of his Leptochelia minuta. These drawings

and the text relating to them, as well as astill earlier account

in the ‘American Journal of Science,’ produced the painful

impression that, so long ago as 1849, the famous American

naturalist must have taken advantage of my inexperience in

such matters at that period to predescribe on his own account

my Dolichochelia Forresti. As he is unhappily beyond the

reach of any personal expostulations, I will only suggest that

the two points in which his account differs from mine may

safely be ignored. He draws a line by which the head is

marked off both dorsally and laterally from the large first

segment of the pereon. But both the West-Indian specimens

described in the Ann. & Mag. Nat. Hist. last month and the

general character of the family Tanaide warrant the inference

that no such line existed, though, while the family character

was insufficiently known, its presence might well have been

thought necessary. In the next place, the first antenne are

said by Dana to have the “ base” or peduncle four-jointed,

with the second joint the longest, from which it is clear that

he has taken the dilatation of the proximal end of the long

first joint as a separate joint. Kroyer, before him, had done

the same thing in a parallel case, and probably misled his

successor. ‘There is good reason to know that, with speci-

mens only a tenth of an inch long, it was not difficult forty or

fifty years back to make such mistakes as these.

Dana reports his specimen as coming ‘from among sea-

weed and small corals, Feejees, Island of Ovalau,”’ and

further remarks :—“‘ This species is Caprelloid in habit. It

was observed by the author attached by its hinder legs to

seaweed, and reaching out the long arms in different direc-

tions as if in search of prey.”

That a minute shallow-water organism like this Lepto-

chelia should as yet be recorded only from two localities so

extremely remote from one another as the Leeward Islands

and the Fijis is at first sight rather striking. But, however

the distribution may have been effected, probably the species

will be found to occur at many intermediate stations whenever

research is more generally directed than it has been hitherto

to the inconspicuous occupants of the coast-lines of the globe.

The exact character of Dana’s genus has long remained

Isopod Genus Leptochelia. L577

misunderstood. This is partly to be explained by the cireum-

stance that Dana’s writings are often almost as inaccessible as

they are celebrated. Leptochelia, with its type species

minuta, was first described in the ‘American Journal of

Science,’ vol. vil. p. 425, 1849. A fuller account was given

in the ‘ Crustacea of the U.S. Exploring Expedition, 1852-

53,’ wherein the remark is made that “ Tanats Edwardsti of

Kroyer (Tids. iv. 1842) is of this genus.” Figures of the

type species were published in the Atlas in 1855.

It must be borne in mind that, besides the extremely

slender and elongate first gnathopods, the type species has

very long upper antenna, in which the second joint is unusually

elongate as well as the first, and biramous uropods, in which

the small outer branch has two joints. Dana says :— Caudal

stylets as long as abdomen, longer branch six-jointed, shorter

minute, two- or three-jointed.” The appearance of a third

joint may have been produced by the crossing or apical

meeting of two setules. In the Tanais Hdwardsit of Kroyer,

to which Dana refers, the gnathopods are stouter, the second

joint of the upper antennz is by Kréyer’s account not more

than a quarter as long as the first, and the outer branch of

the uropod is distinctly one-jointed. When Bate and West-

wood in 1866 adopt the genus Leptochelia for Kriyer’s

species, they declare that the uropods are “ unibranched,”

distinguishing the genus from Paratanais by the fact that the

pleon “ has only a single branch to the caudal pair of pleopoda

attached to the sixth segment ;”’ and again, in their specific

description, they repeat that ‘the posterior or caudal pair of

pleopoda consist of a single multiarticulate branch.” They

give not the slightest intimation that both the authors to

whom they refer had described the appendages in question as

double-branched. In 1878 the late Oscar Harger, in his

‘Report on the Marine Isopoda of New England and adjacent

waters,’ makes Dana’s Paratanats a synonym of Leptochelia,

supposing the former genus merely to represent the females

of the latter, but at the same time being well aware of the

structure of the uropods in the various species which he

groups under the same generic name; so that he says in

regard to the uropods, “ the outer ramus may also consist of

more than one segment.” He remarks, too, that the type

species, “Z. minuta, possesses all the characters of Para-

tanais that could occur in the male.” This way of putting

it was not sufficiently direct to warn other writers of the

differences between Dana’s species and the Tanais Edwardsii

of Kroyer, with which Dana had himself compared it.

Accordingly in 1880, and again in 1886, Professor G. O.

158 Rey. T. R. R. Stebbing on the

Sars (followed in the latter year by Norman and Stebbing)

assigns to Leptochelia two characters which are not appro-

priate to the type—one, that the upper antenne in the male

have the flagellum adorned with bundles of sensitive cilia;

the other, that the outer branch of the uropods is uniarticu-

late. He mentions also that the immobile finger of the

gnathopods is strongly tuberculate within, whereas in

L. minuta it is very weakly tuberculate. Beddard also,

in 1886, in his Report on the ‘Challenger’ Isopoda,

when describing his genus Neotanais, says that, “as in

Heterotanais, the exopodite of the uropoda is distinctly two-

jointed, and this character distinguishes both genera from

Leptochelia, Dana.” Lastly Hansen *, in 1895, figures the

uropods of his Leptochelia affinis with the outer branch one-

jointed.

Thus we find, according to the various accounts of the

genus Leptochelia, that the uropods have no outer branch

and that they have an outer branch, and in the latter case

that the branch is one-jointed, that it is one- or two-jointed,

that it is two- or three-jointed, or that it is two-jointed. The

last view I believe to be the correct one, so far as the type

species is concerned.

The following list shows the species which have been

referred to Leptochelia, and distinguishes the character of the

uropods :—

Of these twelve specificnames Hdwardsii and algicola may be

dismissed as synonyms, filum and brasiliensis as having no cer-

tainty of position, ceca as obviously belonging elsewhere. The

reasons for referring limicola to Ileterotanats are somewhat

hypothetical, since /émico/a is known only in the female, while

the principal distinction of Heterotanais consists in the gnatho-

pods of the male, which, instead of being strongly chelate,

are very imperfectly so. ‘he group formed by Savignyi,

dubia, and neapolitana presents no difficulty in itself, and

might very well be separated under a new generic name from

Leptochelia minuta. But to this Leptochelia rapax interposes

an obstacle, for this species agrees with the group just men-

tioned in having the one-jointed outer ramus of the uropods,

but agrees very closely with LZ. mdnuta in the elongate

enathopods of the male, with feebly tuberculate immobile

finger, and in the considerable elongation of the first antenne.

For the present, therefore, it seems advisable to leave the

five species last-named as constituents of the genus Lepto-

chelia, making the definition of it more comprehensive by

recognizing that the outer ramus of the uropods may be

either one- or two-jointed, and by omitting such details in

regard to the antenns and gnathopods as have been found to

be unsuitable to some of the species. L. dubtéa seems to be

rather doubtfully distinguishable from L. Savignyt.

Hansen’s species, published last year, was described from

a single female specimen taken at St. Vincent, Cape Verde

Islands. Hansen considers that, on the whole, it makes a

near approach to Leptochelia dubia (Kroyer), but he remarks

that it differs from all hitherto described species of the genus

in having only four joints on the inner branch of the uropods.

In this respect it will be observed that it makes an approach

to Leptochelia rapax, and, by accepting affinis as a sixth

species of Leptochelia, we permit the inner ramus of the

uropods to consist of either four, five, six, seven, or eight

joints. Bate and Westwood, by their description of Lepto-

chelia Edwardsi, would carry the number up even to nine ; but

160 : Myr. J. H. Hart on

in their figure, with unexplained inconsistency, they represent

only six.

“ Tanats (Paratanais ?) brasiliensis” is described by Dana

as having the caudal stylets simple, six-jointed. But he

recognizes the chance of his having overlooked the outer

branch of the uropods and the likeness of the species to

Kréyer’s Tanais dubius. Sars accepts it as Leptochelia

brasiliensis. Yet, though it is probably the female of some

Leptochelia, specifically it remains indeterminate.

The only other Paratanais described by Dana is Para-

tanais elongatus from ‘the Sooloo Archipelago.” This,

therefore, is the type, and it has the inner branch of the

uropods two-jointed, the outer one-jointed, whereas in this

genus, as redefined by Sars, each branch of the uropods has

two joints. Here also, perhaps, a slight modification of the

definition will suffice.

XXJII.—Atta (Bcodoma) cephalotes, Latr. : “The Soldier.”

By J. H. Hart, F.L.S.

In studying the various forms of the inhabitants contained in

a nest of the ‘ Sauba ” or “ Parasol-Ant ” I have observed :—

(1) males, (2) queens, (3) soldiers, (4) large workers,

(5) smaller workers, and (6) nurses.

Lubbock gives only five classes—1, 2, 3,4, and 5—the

fourth and fifth of which he calls large workers, and states :—

“‘ Bates never saw either of the last two kinds do any work at

all, and was not able to satisfy himself as to their functions.

They have also been called Soldiers, but this is obviously a

misnomer—at least they are said never to fight. Bates

suggests that they may serve in some sort as passive instru-

ments of protection to real workers. Their enormously large,

hard, and indestructible heads may be of use in protecting

them against the attacks of insectivorous animals. They

would be on this view préces de resistance, serving as a foil

against onslaughts made on the main body of the workers.”

Lubbock then states* that he is not satisfied with this

solution, and thinks the true function of these large-headed

forms is not yet satisfactorily explained.

I have personally had the advantage of studying the insect

both in Nicaragua and in Trinidad, and I must agree with

Atta (Gicodoma) cephalotes, Latr. 161

him, for the observations I have made clearly show the

“Soldier,” or no. 3 of my set, to be actually a “ soldier,”

and a most resolute detender of the nest in which he (?)

resides.

If a nest of Atta cephalotes is visited and the slightest

disturbance made, the tirst members which appear are the

‘¢ soldiers,’’ who will seize any and every thing presented to

them or that comes in their way. I have suffered myself

to be bitten on the hand by one of them, and have watched

the process.

The mandibles are first fully extended and the skin is firmly

grasped by the points, but as the pressure is continued the

mandibles meet below the skin to a depth of 3 to 4 millim.,

causing a neatly incised wound sometimes as much as 5 to 6

millim. in length, and resembling a cut from a small knife.

The grip of the animal is so tenacious that it will allow its

head to be pulled from its body betore it will quit its hold, and

will fix to iron, flesh, or cloth with equal facility.

Mr. Lunt, my assistant, when visiting a large nest had

thick woollen socks so cut through by the “soldier” of this

species that they were useless for further wear.

If a nest is visited and an alarm caused by putting a piece

of iron, stick, or other instrument into their holes, it is sure,

when removed, to be covered with the “ soldier ” ants hanging

to it by their mandibles.

In addition to these facts I have seen in my artificial nests,

which I have had under observation for some three years,

many tights with the “ soldier.”

The workers of Atta octospinosa, Reich., among which

there are no “ soldiers,” can easily kill the ‘ soldier” of

A. cephalotes: they proceed as follows:—The “ soldier ” is

attacked in regular order by s¢x or eaght of the octospinosa,

who completely surround their victim, and watch their oppor-

tunity to seize the outer joint of his (?) legs. ‘This is cut off,

and gradually the creature is deprived of these appendages

joint by joint, and ultimately is lett to move on mere stumps,

when it dies in a few hours. In doing this, the smaller

insects take particular care not to approach within the reach

of the “ soldier’s ’’ mandibles, as to do so is certain destruction

to the individual who has such temerity ; they seldom do so,

but, on the contrary, the object appears to be to keep as far

away as possible and to hold the legs fully extended while

effecting their object of cutting them off piece by piece.

“Soldiers,” again, when placed together fight among

themselves, and a bodiless head and thorax is trequently seen

stalking about after such meetings. When placed together

162 Mr. H. M. Bernard on

in spirit they at once seize one another and form themselves

up into a complete mass, which is tightly held together by

the mandibles.

The “soldier”? of Atta cephalotes is the same in form in

Nicaragua as in Trinidad, and possesses the same powers of

defence and offence.

XXIV.— The Sense of Sight: Sketch of a new Theory.

By H. M. Bernarp, M.A. Cantab., F.L.S., F.Z.S.

For nearly ten years I have been engaged in endeavouring

to find an explanation of light sensations. I have at last

worked out a theory capable of connecting and explaining

most of the phenomena, and, what is still more important,

apparently capable of demonstration. I am now engaged in

arranging the evidence; but in the meantime I am urged to

publish a short abstract of the conclusions arrived at, because,

in the first place, the duties which I have undertaken at the

Natural History Museum must necessarily retard the publica-

tion of a fuller treatise, and, in the second place, because, the

subject being one of wide interest, physiologists and zoologists

will have an opportunity of recording observations either for

or against the theory, which will be useful towards the

ultimate solution of this important problem.

In the following pages I propose to confine myself solely to

a statement of my own theory, abstaining entirely from all

criticism, and even from all mention of existing theories,

except when the subject requires it.

A long series of observations on different Metazoa, ranging

from the Platodes to the Vertebrates *, have convinced me

not only that wandering-cells, apparently acting as scavengers

among the tissues, collect granules discharged trom other cells

or matter to be afterwards formed into granules, but that the

importance of this process is not exclusively physiological.

These granules are conveyed by the wandering-cells to organs

which lead out of the body, where they may be put to

secondary uses. ‘The granules themselves not only differ

greatly in different animals, but may also differ in one and

the same animal. The secondary utilization of these granules

takes place, in many cases at least, by their transference from

* Not including, however, the Echinoderms; and on these cf. Mr. H.

Durham’s paper in the ‘Quarterly Journal of Microscopical Science,’

vol, xxxili. p. 31. ,

the Sense of Sight. 163

the wandering-cells into those of other tissues to which they

have been brought. Just as the cells of the tissue where

they originated passed them on to the wandering-cells, these

can again pass them on to other cells. I may, perhaps,

recall the collections of pigment-cells within the ovaries of

frogs, which appear to be passing their coloured granules into

the eggs.

Chief among the tissues receiving the loads brought to

them by the wandering-cells is the outer skin. Here they

can be seen discharging their granules to the epidermal

cells, which utilize them in various ways. ‘They take part—

probably a very important part—in the formation of epidermal

protective structures, chitinous and horny cuticles, &c. Slime-

glands appear to use them in the formation of their secretions.

Or, again, they are stored up, altered or unaltered, as the

colouring-matters of the skin and of its derivatives.

Remarkable among skins coloured by these granules are

those endowed with what is known as the chromatic function.

In these cases the wandering-cells have either been arrested

in the connective tissue just beneath the skin, or have given

up their granules to connective-tissue cells, the resultant

‘* chromatophores”’ coming under partial control of the nervous

system. The highest specialization of this is seen when, in

two or more layers of cells containing differently coloured

granules, these granules change their positions in the bodies of

the cells, spreading out or crowding together at different times

and in different degrees, so as to produce an astonishing

play of colour. But even in such cases it is probable that

individual granules escape from these secondary detentions and

reach the outer cells of the skin, where they may be needed

for various more primary functions.

Leaving out of account those cases which are complicated

by secondary association with the nervous system, we have

abundant evidence to show that, although the wandering-cells

under discussion somehow travel to their respective destina-

tions in the dark, they are very sensitive to light, towards

the source of which they move. This is a common pheno-

menon among unicellular organisms both animal and vege-

table, and it is specially marked when the contents of the

cells are coloured. It is in’ large measure to this attraction

that the great abundance of the granule-bearing cells or of

transported granules in or under the skin is due.

The theory which I desire to propound is, that it is to this

constant striving of wandering-cells to travel towards the light,

and, if possible, to escape altogether from the cell-complex

of the body in which they originated (or, aes only to

164 Mr. H. M. Bernard on

discharge their contents at the surface), tliat the animal king-

dom owes its many visual orgaus. It is legitimate to assume

that the laden wandering-cells would flock in excess towards

the source of the brightest light. At such points complications

would arise between these invaders and the more stationary

tissues which bar the way. Out of such complications, I be-

lieve, eyes have arisen. The sensory nerves in those parts of

the skin most strongly and frequently illuminated become

associated in different ways with these complications, either

with the struggling crowd of wandering-cells collected in

excess at such bright spots, and set in commotion whenever

light falls on them, or with other cells into which these

wandering-cells have discharged their contents to over-

crowding, and which, on this account, practically become

equally restive whenever subjected to light-stimulus. For it

is important to note that these granules appear to make the

same endeavours under light-stimulus to leave the cells in

which they find themselves and travel towards the light, as do

the wandering-cells themselves to escape from the Metazoan

body.

We may enumerate some of the different types of eye

which can be thus accounted for.

1. Simple epidermal cells associated with epithelial sensory

(tactile) cells become filled with granules to overcrowding.

The escape of these granules at the exterior is hindered by

the excess of slime to which they themselves have contributed.

‘lhese granules, crowding forward whenever stimulated by

light, but unable to escape fast enough, exert a lateral pressure

upon the adjacent sensory cells. The excess of slime pro-

duced by the continual crowding forward of the granules may

result in the formation of vitreous bodies or lenses. Eyes

arising in this way occur, for instance, in some Mollusks.

2. ‘The wandering-cells may be arrested by, or collect in

excess round, epithelial glands which have sunk below the

surface. This would be especially the case round gland-

cells or glands which contained glassy or refractive contents

in the line of light, such bright points having, according to the

theory, an especial attraction tor the wandering-cells. The

striving of the wandering-cells either to push on through, or to

pass on their contents to, these cells would again be appreciated

by sensory nerves. Further, assuming, and there is ground for

the assumption, that the granules in many cases contribute to

the formation of the slimy or refractive secretions in such glands,

these secretions would, owing to the excessive supply of

granules, tend to develop abnormally, and thus help to form

a more efficient dioptric apparatus than the simple gland

the Sense of Sight. 165

afforded. The eyes in certain Platodes, and apparently also

in Leeches, are essentially of this type.

3. In cases where a rigid chitinous cuticle is present, the

different ways in which the cells containing the granules

become associated with the sensory nerves are very numerous.

These cells may belong either to the skin or to the connective

tissue, or are, perhaps, collections of the wandering-cells

themselves. Leaving these differences on one side, we may

roughly divide the eyes arising under chitinous cuticles into

two groups—those in which the sensory nerves running close

under the cuticle turn round and face the advancing crowds

of granule-bearing cells or granules, and the other in which

the sensory nerves run with the stream towards the light. In

both these divisions we have many specializations of the

different cells composing the ultimate complex or organ, while

in all cases the excess of the advancing granules, which nor-

mally contribute an important constituent to the hard cuticle,

leads to the formation of rods, rhabdomeres, crystalline cones,

and lenses. We have, then, here to assume that individual

granules, though evidently impeded by the structure of the

complex, continually succeed in their efforts to advance and

in some way end by fulfilling their normal destiny of helping

to build up chitin.

The secondary character of visual organs seems to follow

from the fact that eyes showing both the positions of the

sensory (retinal) cells described under this heading occur in

one and the same animal class, e. g. in the Arachnida and in

the Mollusca.

Before passing on to the typical complicated vertebrate eye

I may refer to the persistent remains of a far simpler kind of

eye which are still to be found among lower vertebrates. I

refer to the ancient pineal eye, which is still recognizable as an

eye in the Lizards. ‘This pineal eye, if its present condition,

say in Hatteria, gives any evidence ot its original morphology,

and it would be difficult to prove the contrary, is of the first

and simplest of the types above described *, and thus mor-

phologically, as well as phylogenetically, is a very primitive

structure. ‘I'he pigment-granules or granule-bearing cells

which, in the functional eyes of that type, contribute to the

formation of the cuticular or gelatinous dioptric apparatus, in

* I have to thank my friend, Mr. Martin Woodward, of the Royal

College of Science, for the loan of sections of the pineal eye of Hatteria,

which leave no doubt in my mind on this point. I may add that I am

greatly indebted to other fine preparations made and kindly lent me by

Mr. Woodward; they have confirmed iu a striking manner many points

in my theory.

166 Mr. H. M. Bernard on

these degenerate eyes appear usually to escape into the cavity

of the eye, in some cases at least, unaltered *.

Turning to the vertebrate eye proper, we are justified

in affirming that, however highly specialized, it is a product

of the same activities as have given rise to the simpler

eyes above described. With regard to its structure, what

chiefly concerns us is the fact that the sensory cells are

turned towards the advancing streams of granules. I feel

justified in speaking of the streams of granules, because, as

is known, not only are these granules carried about in cells,

but they are apparently capable, under tie action of stimulus,

of independent movements within cells, and, further, can pass

from cell to cell. Amoceboid movements have been claimed

for the individual granules from the eye of vertebrates when

floating free in a suitable medium. ‘That the granules in

many eyes are highly complex bodies (perhaps secondarily

specialized), and not simple concretions, follows from the fact

that they seem to contain a staining kernel of chromatin, and

in the eye of the crustacean Apus they are invested in a fine

hyaline layer of matter and can be found dividing t.

Passing by cornea, iris, lens, and other accessory structures,

we may say that the vertebrate eye, as a sense-organ, consists

essentially of a thick layer of nerve and sensory tissue effec-

tually opposing, or only greatly impeding, the advance of

granules contained in the cells of an epithelium which is in

contact with this sensory layer over its whole extent. These

granules should normally reach the surface of the body and

take part in the formation of the external protective structures.

They are, however, kept back, but are stimulated to renewed

efforts every time the light falls on them. This attack on

the nervous-tissue layer, to try and force a way through

whenever attracted by the light, I believe to be the secret of

our light sensations.

We may point out here that albinism, which has hitherto

prevented physiologists from seeing in the movements of the

pigmented granules any essential factor in the production of

Jight sensation, is no difficulty to this theory {. ‘lhe granules

themselves are doubtless there in some form or other, only

they lack the colour. This deficiency may be quantitative or

* Cf, W. Baldwin Spencer, ‘On the Presence and Structure of the

Pineal Eye of the Lacertilians” (Q. J. M. 8. xxvii. 1887).

t In conjunction with the normal] granules others of such purely excre-

tory matter as guanin are found in some eyes. This phenomenon is quite

in accordance with our theory.

{ The seductive analogy between the eye and a photographic camera

with its sensitive films has also had something to do with drawing a ten-

tion away from the pigmented granules.

the Sense of Sight. 167

merely qualitative *. That these granules, in spite of this

deficiency, seek the light, we gather from the fact that the

outer skin of albinos is, but for the absence of colour, appa-

rently normal. The connexion between the granules an

integumentary protective structures has already been referred

to, and need not here be repeated. I may merely remark

that we have almost every gradation between dark-skinned

people with coal-black eyes, through fair-skinned people with

less deeply pigmented eyes, to albinos with so little pigment

in their skins and eyes that, if present at all, it is not at first

sight apparent. Perhaps faint traces might be found if the

granules of the eyes were specially examined tor that purpose.

My own, all too limited, observations on this point have so

far left me undecided.

We may conclude, however, that the colour of the granules is

not essential, for, without it, they strive to reach, and in the

skin succeed in reaching, the surface. Nevertheless the fact

that the granules collected in visual organs are, as a rule,

deeply coloured, shows that the colour is very useful. Its

absorption of the light prevents a diffusion injurious to clear

vision, and, perhaps, also increases the vigour of the move-

ments of the granule by slightly raising its temperature.

We have, then, these two tissues to consider :—

(1) The layer of cells (choroidal or pigment epithelium)

containing the usually pigmented granules, which seek to

force a way towards the source of the light that stimulates

them to action.

(2) The thick layer of tissue, chiefly nervous and sensory,

which blocks the way, 7. e. the retina.

We will, for convenience, take the latter first.

The Retina.—It will be freely admitted that it is not easy

to give a simple morphological definition or description of

this complicated structure. While certain of its elements are

fairly well understood, we are still far from a complete com-

prehension of it as a whole. In fact, the application of the

most recent and approved methods of staining tend, it seems

to me, to make it more enigmatical than ever. What follows

is therefore put forward purely tentatively. The retina is a

many-layered sensory epithelium, in which originally, ¢. e.

when less highly developed, the cells stretched as fine thread-

like strands between its limiting membranes, the nuclei being

suspended on these threads at different levels. ‘his is a

* Pigmented granules lose their colour in the process of being trans-

formed into cuticle or slime within epidermal cells. This fact largely

explains why the two have not hitherto been associated in the manner

suggested above.

168 Mr. H. M. Bernard on

common type of sensory epithelium, and, as far as the retina

is concerned, describes fairly well the undifferentiated portion

of that structure as seen in the eyes of tadpoles round the

rim of the retinal cup, although the layers of nuclei are

even here already numerous. For some little distance round

the outside of this rim the granule-bearing cells of the

choroidal epithelium are in close contact with the external

limiting membrane of the retina—that is to say, there are no

rods or cones keeping them at a distance. As we go further

from the rim these begin to appear, and the manner of their

appearance seems to me to be very significant.

What first strikes one is that they are far less numerous

than the nuclei, which at this point have still further in-

creased in number without any very marked signs of differen-

tiation among them. So many nerve-cells with so few

terminal structures involuntarily suggest that these end-

structures, the “ rods and cones,” must contain many separate

nerve-fibrils. This suggestion finds support in the irregular

thickness of the rods and cones. Some receive far more

nerve-fibrils than others. There would thus be no morpho-

logical difference between these structures, 7. e. between

rods and cones, whatever difference there might be among them

as to length or thickness. The rod-like structures, however,

are not composed wholly of nerve-fibrils; they may be

described as cuticular outgrowths from the sensory layer

projecting into the granule-cells lying in contact with it.

The cuticular outgrowths appear to rise from that layer of the

sensory cells which lies just within the external limiting

membrane, while from the crowd of undifferentiated sensory

cells in the deeper layers (lying nearer the centre of the

eye) fine nerve-fibrils descend from all sides and run out

along (? within) the supporting cuticular rods prepared for

them. This will explain the fibrous character of the proto-

plasm ascending from each rod and surrounding its own

special nucleus, which can be clearly seen under the micro-

scope in sections of the retina of the frog. It might also be

associated with the longitudinal striation which has long been

attributed to these structures.

From all that has been said above as to the connexion

between the granules in the wandering-cells and integu-

mentary protective structures, the development of cuticular

rods is not surprising even in such a place. We have but

to assume that a certain number of granules succeed in forcing

their way into the outer layer of cells in the opposing sensory

tissue-layer, and that these cells work them up into protective

structures. The structures take the form of rods projecting into

and still further impeding theadvancing stream of the granules.

the Sense of Sight. 169

Microscopic evidence can be adduced which leaves little doubt

that the pigment-granules do actually yield at least some

portion of the material out of which the rods are built up.

If this is indeed the case, it would go far towards establishing

the theory here set out, that the granules endeavour to force

their way forward towards the source of light and into the

opposing layer,which layer, being composed mainly of sensory

cells, is in consequence stimulated,

In the lighest vertebrate eyes these cuticular rods may be

of great length, forcing the granule-bearing cells back from

the external limiting membrane, while, again, the great

thickness of the retinal tissue necessitates considerable diffe-

rentiation of its elements for support and, perhaps, on the

one hand, for nourishment, and on the other for the removal

of waste.

The Choroidal Epithelium.—Having thus briefly sketched

the opposing sensory tissue, we turn to the layer of cells con-

taining the granules which seek to reach the surface of the

body whenever stimulated by light. The bodies of these

cells are forced back from the external membrane of the

sensory layer by the cuticular outgrowths just described, but

they remain attached to it by fine protoplasmic processes.

These protoplasmic strands thus run up among the cuticular

rods ; or, to describe it in another way, just as the granule-

bearing cells, on being arrested by dense epidermal tissue on

their way to the surface of other parts of the body, penetrate

as far as they can between the cells composing this tissue by

means of pseudopodia, so here the pigment-bearing cells

penetrate with their pseudopodia between the rods protecting

the retina until they are stopped by its limiting membrane.

In the case of the eye for certain, and from the darkening of

the skin by exposure to sunlight probably in this case also,

the granules are stimulated to escape along these pseudopodia

by the action of light. In the case of the eye very tew

apparently succeed in getting away at the tips of these cell-

processes through the membrana limitans externa, and,

baffled, they have to return to the cells in which they are

imprisoned. In the case of the skin, however, their escape in

considerable numbers into its outer cell-layers seems not only

probable in itself, being quite in accordance with what the

microscopic study of skins teaches us, but seems also to be

required by the dark colour familiar to us under the name

of sun-burning, which persists for some days, or even weeks,

after the exposure has ceased *.

* Dark people, as a rule, burn darkest; in fair people the granules

invading the skin are apparently not coloured, but local immigrations of

coloured granules, perhaps from blood-vessels, give rise to freckles, If

170 Mr. H. M. Bernard on

Returning to the eye, the granules may be described as

advancing and retreating according as they are stimulated by

light or as the stimulus is withdrawn. It may also be that,

like the kindred chromatophores of the skin of animals en-

dowed with the chromatic function, they are susceptible to

nerve-stimulation, inasmuch as it is said that the granules

advance in a darkened eye if the companion eye is stimulated

by light. But this “‘ sympathetic ” advance might perhaps be

explained in another way.

While the advance is apparently due to the stimulus of the

light, the retreat may be due to lateral pressure on the part of

the cuticular rods. That such a pressure exists we may perhaps

conclude from the fusiform shape assumed by those granules

which, being on the outer portions of the cells, slide up and

down most trequently between the rods. The pointed ends of

these fusiform bodies lead one at first naturally to see in them

the instruments forstimulating the nerves. It has been pointed

out that they might, for all we know, vibrate as rapidly as cilia.

It was long before I became convinced that this shape was

chiefly useful in enabling the granules to torce their way up

and down rapidly between the closely packed rods, and also in

enabling them to form compact masses, the fresh arrivals

wedging themselves in between those in front. The pointed

ends have, I am convinced, no other function than that of

facilitating their alternate advancing and retreating move-

ments, for rapid crowding at special points and equally rapid

dispersal.

The actual cause of Light Sensation.—At first sight it must

appear that no theory can be simple which seeks to explain

how the eye can accurately register (as it does, say, in the

process of reading) several hundreds of distinct words, each

composed of many letters, per minute, each letter forming an

image which remains but the fraction of a second. My

theory, however, claims to be, comparatively speaking, a

simple one. It assumes the existence of no forces or sub-

stances which we do not know to exist, not only in the body,

but even in the eye itself; and it is, moreover, applicable to

every eye, known for certain to be such, in the animal

kingdom.

Just as the play of colour in the skins of animals endowed

with the chromatic function is due to the constant shifting of

the variously coloured granules within the chromatophores, so

these granules really contain excretory matter which should be discharged

at the surface of the body, we should be justified in concluding that the

exposure of the skin to light must be generally beneficial to health,

the Sense of Sight. 171

the rapid changes in our sensation of sight are, I believe, due to

slight shiftings, in obedience to the changing play of the light,

of the granules between the highly sensitive rods of the retina.

The distances through which the granules have to move

individually can be shown to be infinitesimal. This fact is of

importance, because one of the difficulties against any such

hypothesis has been stated to be the great distance the

granules would have to travel from the pigment-cells all the

way up between the rods, and the consequent slowness of the

reaction, which we know from experience to be practically

instantaneous. Closer inspection shows that this difficulty

does not exist. No eye is fit for vision in which the granules

are contracted into the body of the pigment-cells, as any one

may prove for himself who suddenly opens the shutters of a

really dark room in which he has passed the night. ‘The

eye, indeed, has to be prepared for, or, in other words, to

“ oet accustomed to,” the light. The general sensation of

light must precede the sensation of any distinct image, and

this general sensation is brought about by the pressing

forward of the granules between the sensitive rods. Before

we have any distinct vision, therefore, the granules are

already in position, actually causing the general sensation,

Not until this is the case are we conscious of any definite

images.

Leaving colour-sensation for the moment out of the

question, these definite images are really only variations in

the intensity of the light. These will be felt in the following

way. Wherea bright light falls, more granules push forward

from the back; where a shadow falls, the push from behind

is relieved. The movements of the individual granules in

order to effect these changes of pressure need only be infini-

tesimal. In a crowded gangway it is often difficult to see, by

any actual movement, who is pushing and who is not. We

all, however, feel instantaneously both when the pressure is

put on and when it is taken off. No one who has watched

the movements of minute organisms under the microscope can

doubt that they would supply us with far greater rapidity

than that required by this theory, for the instantaneous appli-

cation or withdrawal of pressure, the distances to be traversed

being, as already stated, infinitesimal.

We may, then, describe our ordinary vision (apart from

colour) as due to constantly varying degrees of relief from, or

increase in intensity in, the general sensation of light

which, during all vision, floods the eye, this general sensa-

tion being caused by the granules pressing forward between

the rods and cones, and varying in numbers according to

172 Mr. H. M. Bernard on

the brilliance of the light. Every shadow, every shade of

a shadow, every dark moving object, every black line of the

book we are reading represents so many reliefs, so many

degrees, so many shiftings, and so many durations of relief

from the pressure which the granules are exerting laterally

upon the sensory nerve-fibrils in some way incorporated with

the retinal rods. ;

Colour-Sensation.—No theory of colour-sensation can be

satisfactory unless it can be shown to be a natural develop-

ment—that is, a development, without sudden break or sudden

addition of new factors, of ordinary light-sensation. It is

satisfactory, therefore, to find that colour-sensation almost

naturally follows from the foregoing description of general

light-sensation.

That there exists some connexion between the granules

and the formation of the cuticular rods is not only

probable itself, but can even, I believe, be demonstrated

under the microscope. We need not now discuss the

details : it is enough for our purpose if this cuticular structure,

the rod, varies slightly in texture in such a way as to be

almost glassy near the external limiting membrane, and from

this point to consist of zones in which corpuscles of increasing

size (though always microscopic) are suspended. That the

rod has some definite texture tending to cause it to break

transversely into short lengths, histologists are agreed. We

are further justified in assuming some heterogeneity in order

to avoid the total internal reflection of the light down to its tip,

which would take place if the rod were a homogeneous glassy

structure. In addition to this specialization into zones, with

different-sized corpuscles suspended in the substance of the

rods, we have only to assume that, of the sensory nerve-

fibrils embodied in e: ch rod, one or more terminate among the

finest corpuscles, one or more among the next coarser, and so on

to the tip, where the coarsest are found. Colour-sensation

would,it seems to me, naturally result from such anarrangement.

We require no more movement among the pigment-granuies

than we required for the appreciation of the ordinary variations

in light and shade. The red rays, according to the law

illustrated daily in the sky, passing through all zones con-

taining the smaller corpuscles, would be caught and dispersed

on all sides by the largest granules at the tips of the rods.

The pressure of the granules already crowded in the “ gang-

ways” would be immediately directed both trom above and

below to the point where the red light is breaking in from

the side. Again, rays of shorter wave-lengths would be

caught by the smaller suspended corpuscles and scattered

the Sense of Sight. 173

laterally among the crowds higher up the gangways between

the rods, when the pressure would at once be increased in the

region of these smaller corpuscles by infinitesimal movements

of the pigment-granules from both directions. In this way

it would be possible to have rods dispersing laterally each

colour of the solar spectrum in succession, beginning from the

top with the violet. How many different zones there actually

are in the longest tapering rods (‘‘ cones”’) in the human eye

can only perhaps be ascertained by a careful analysis of our

sensations. It was long ago shown (Young-Helmholtz theory)

that three elementary sensations—red, ereen, and violet—would

be sufficient to explain the rest ; but, according to our theory,

there appears to be no reason why there might not be more.

According to this theory white and black would not be

colours, but merely stimulation or absence of stimulation of

the rods as wholes.

The curious phenomenon of colour-blindness in individuals,

and perhaps also the assumed existence of racial deficiencies

in the matter of colour-sensation *, might be explained as due

to a failure to develop the necessary specialized gradations

in the sizes of the corpuscles suspended in and composing the

retinal rods. It is, on the other kand, possible that we have

not ourselves reached the limit of perfection attainable in this

direction.

It may perhaps be added that, while the active force

causing the stimulation of the nerve-endings for the different

colours would in all cases be the same, namely pressure on

the sides of the rod by the crowded granules in the gangways,

the actual stimulus on the nerve-fibrils would be different for

each colour—in one zone of the rod the nerve-ends would be

nipped between larger, in another zone between smaller,

corpuscles, which also might perhaps differ in shape.

We have, then, briefly traced a theory of light-sensation

and of vision which embraces all known eyes, from the

simplest to the most complex, and which accounts for the

most perplexing phenomena by an appeal to known factors

alone. But, however connected and plausible a theory may

be, the question of most importance always is, can it be

proved? Is it anything more than a mere working hypo-

thesis? While admitting that this theory is, and may perhaps

long remain, only a working hypothesis, I think that it is

something more. A great part of it, dealing with the elemen-

* The ancient Greeks, judging from the very limited colour vocabu-

lary of their poets, are thought not to have been so specialized in this

respect as we are to-day.

174 Mr. H. M. Bernard on

tary stages in the development of the sense of vision, is capable

of actual demonstration, and on this solid foundation the rest

is built. The truth of this most important “ rest,” which

includes the phenomena of clear vision such as we know it,

can only perhaps be finally established by degrees. Facts

are, however, not wanting which make me believe that a

rigid demonstration of it is not far off.

I will point first of all to those observations which tend to

show that, in cases of frogs killed after their eyes had been

exposed to different coloured lights, the pigment is found

massed in a manner not unlike that in which, according to

this theory, it should be massed. A chromatic scale, some-

what like that which I have sketched theoretically, is actually

claimed to exist. The red light is found to mass the pigment

round the tips of the rods, and so on in regular order upward.

It is hardly to be expected that the records of actual dis-

coveries in connexion with this chromatic scale would tally

exactly with the requirements of the theory. The extreme

mobility of the pigmented granules would render their per-

sistence in any position, after the conditions which induced it

were changed, highly improbable. It is, in fact, a matter of

surprise to me that they show as much of the theoretical

chromatic scale as they are said to do *.

Again, evidence in favour of the theory, to some minds

perhaps of even greater weight than that already adduced,

may be found in the fact that it enables us to explain such

collateral phenomena as irradiation, contrasts, after-images.

Irradiation would be due to the increase in size of any

bundle of strongly illuminated rods owing to the great crush

and continued pressure of granules into the gangways between

them. ‘This increase in size of the area occupied by the

illuminated rods would press upon the adjacent rods all round

for a short distance, the pressure being soon neutralized by

the emptying of the gangways (by the squeezing out of the

granules) between these adjacent rods.

On the withdrawal of the light the crush in the gangways,

if it has been very great owing to the brilliancy of the illu-

mination, takes some time to relieve, during which time we

have a positive after-image. As soon as it is sufficiently

relieved, the granules which had been forcibly squeezed out

from between the adjoining gangways force their way back

again, and in doing so seem to assist in squeezing the recently

congested passages empty. The positive after-image then

changes, as in a moment, into a negative after-image with a

the Sense of Sight. 175

corona. Only slowly is the state of equilibrium reached ;

we apparently have, indeed, a veritable “ oscillation” of

pressure, alternately within the originally stimulated area and

the region immediately surrounding it.

If, again, the congestion in the gangways between the rods

of an illuminated area is not equally distributed throughout

their whole length, but is localized, say, at their distal ends,

which is, according to the theory, the result when the illu-

minating rays are red, the pressure on the surrounding region

will be different. It will not affect the whole length of the

adjacent rods, but only their distal ends. ‘The pressure

exerted on the distal ends of adjacent rods will squeeze the

eranules which were arranged here both up and down, It is

probable that more will be squeezed up than down, as the

downward attraction of the red rays would tend to relieve

the pressure at the upper ends of the rods in the illuminated

area, and render this the direction of least resistance within

the gangways of the adjoining rods. While, then, the red

light is massing the granules between the distal ends of the

rods in the illuminated area, the pressure caused by these

localized assemblages of granules leads to a slight massing of

granules above the distal ends of the rods in the surrounding

region. Here it should give rise to a different colour-sensa-

tion from red. Indeed, it is a necessary corollary of the

theory of colour-sensation here proposed that the irradiation

fiom any coloured image must be of a different colour. Daily

experience shows this to be actually the case. According to

this theory, then, the difficult phenomena known as “ colour-

contrasts” have hardly to be accounted for; they take a

natural and necessary place in the scheme *.

One more point in evidence as to the truth of this theory.

It is true that it is again indirect evidence, but its weight

cannot be ignored. ‘There has never yet, so far as I know,

been any satisfactory explanation of the curious deception

presented by what are known as Zollner’s parallels. If,

however, irradiation is due to a real mechanical pressure, the

apparent divergence of these lines admits of very simple

explanation.

We may therefore briefly describe the development of

visual organs in the animal kingdom as follows :-—

- Under the influence of light certain organisms travelling

toward the light seek either to leave the Metazoan body alto-

gether or else to discharge their contents at the surface. Such

very different interpretation.

176 On the Sense of Sight.

emigration cannot take place without the cognizance of the

nervous system, and where it is most pronounced, ¢, e. in the

most frequently illuminated parts of the body, complications

arise between the fugitives and the other tissues, notably the

peripheral nerves. My suggestion is that out of these compli-

cations all the known eyes of the animal kingdom, the most

complicated as well as the most simple, have in one way or

another arisen.

If this theory can be established, a fascinating field of in-

vestigation will be opened out to goologists. If such

specialized structures as eyes have arisen simply by the

crowding to excess of pigmented granules in the most fre-

quently illuminated parts of the integument, may not other

less specialized integumentary structures in the animal

kingdom be also explained by variations in the numbers of

the granules received by their formative cells? Leaving out

of account the circulatory system, the tissues among which

the wandering-cells have to travel towards the surface are not

all equally dense, and even if soft may for one reason or

another be impenetrable. Hence the migrating swarms of

wandering-cells would tend to divide up into streams which

would reach the surface as such, causing cuticular thick-

enings or prominences at such spots. We might expect to

find specializations of the integumentary cuticular formations

showing some slight correspondence with the sizes and im-

portance of these streams. In investigating the movements

ot wandering-cells, which, avoiding the canal-system supplied

by the blood-vessels, may be described as travelling across

country, gravitation and the active movements of the body,

as well as light, must certainly be taken into account. It

is not improbable that a slowly cumulative selective action is

taking place, those cells containing the most deeply pigmented

granules better overcoming the attraction of the earth under

the light-stimulus than those carrying less- or non-pigmented

granules.

In the fuller treatise containing a detailed account of the

evidence, direct and indirect, on which this theory is based, I

propose to give simple diagrams to illustrate more fully the

explanations, here thus briefly sketched, of colour-sensation,

irradiation, colour-coutrasts, and other kindred phenomena.

I propose also to include an account of some of the subjective

phenomena, attention to which first drew me on to seek an

explanation of vision in general.

Stridulating- Organ in Trechona zebrata. 177

XX V.—On the Presence of Wood-Mason’s Stridulating- Organ

in Trechona zebrata (Walck.). By BR. I. Pocock.

Mr. THomas WorkMaN of Belfast has recently kindly drawn

my attention to the paper entitled “ Remarks on the Falces

and Maxille of Spiders,” published in the Annals & Mag.

Nat. Hist. (8) xix. pp. 258-259, pl. x. fig. 3 (1867), in

which Mr. John Blackwall describes and figures part of the

stridulating-organ of one of the Theraphoside, which he

called Mygale zebra. On p. 259, after discussing the inap-

propriateness of the term teeth as applied to the abbreviated

spines which stud the base of the maxilla and the apex of

the labium in the spiders of the family “ Mygalide,”’ he

observes: “ but to a remarkable group of spines, situated on

the superior surface of the maxilla of Mygale zebra, and

clearly indicating, by its position and structure, that the

principal function it performs must be that of mastication, the

appellation of teeth appears to be more appropriate. ‘I'he

spines composing this group, which are of a dark-brown

colour, and have their pointed extremity directed towards the

inner margin of the maxille, are fewer in number, enlarged

at the extremity, and much longer and more distinct near the

posterior end of each group than the closely compacted ones

that form its anterior part. ‘These spines, by their figure and

arrangement, present a highly interesting subject for inspec-

tion under the microscope.” ‘This description and the figure

that accompanies it leave no room for doubt that the author

had betore him the cluster of modified hairs constituting the

notes or keys of the stridulating-organ that was subsequently

described by Wood-Mason. ‘I'hat he failed to discover the

true significance of the organ is perhaps not surprising, seeing

that he had never been previously informed, as had Wood-

Mason, that these spiders are able to emit sounds.

The chief interest, however, of the discovery lies in the

fact that Mygale zebra, or rather Trechona zebrata, as it

should be called, is a South-American species; and no other

member of the family from this country, which is perhaps, so

far as the Theraphoside are concerned, the richest in the

world, is known to possess this stridulating-organ. In fact,

in connection with this subject, | remarked, on p. 168 of the

‘Annals’ for February last, “ no organ resembling either of

those [the two types of stridulators occurring in the oriental

genera*] mentioned above is found in any genus that I have

examined of the following Neotropical groups :—Aviculariez,

Eurypelmatez, Theraphosez, and Homceommatee.”

The genus Trechona, however, belonging to a distinct sub-

family—namely, that of the Diplurine,—and represented in

the National Collection by a single dried example, which will

very possibly prove to be Walckenaer’s type, I did not

examine for this organ, for fear of causing needless damage

to a valuable and unique specimen. But upon reading

Mr. Blackwall’s article, 1 immediately took the necessary

steps to verify his statement, and was rewarded by finding

the organ almost exactly as he described it. The set of notes

on the maxilla is of large size, and occupies nearly the whole

length of the inner surface of this segment. The notes com-

posing the distal two-thirds of the group are black and

thickly clustered together ; they are not, however, short and

spicular as Blackwall’s figure represents, but long and straight.

Those, on the contrary, that compose the proximal third of the

cluster are thicker, more separated from each other, curved,

and arranged in a single line, the individual notes gradually

decreasing in length as they pass from the centre of the

cluster to its proximal end. ‘The modified hairs on the op-

posable surface of the mandible, which Blackwall does not

mention, are constructed on very much the same plan as the

corresponding hairs that J have described in Psalmopceus

Cambridgti *—that is to say, they consist of a small number

of long, thick, but apically filiform sete set on the posterior

portion of the lower edge of the jaw, and these pass into a set

of rigid sete, which ultimately blend with the hairs at the base

of the fang.

A point to be noticed in connection with the occurrence of

this remarkable organ in a Neotropical genus belonging to

a subfamily with which the Oriental stridulating Seleno-

cosmiide seem to have no special affinity, is the unavoidable

conclusion that substantially the same structure has been

developed twice over. Moreover, as I have pointed out, the

instrument is also found in another spider, Jdiommata Black-

wallii, Camb., which belongs to yet a third subfamily. So

that apparently we have evidence that the organ has been

independently acquired three times within the limits of a

single group of spiders.

This conclusion at once raises the question as to the value

of the character in uniting the genera that I have grouped

together as Selenocosmiide. For it may well be asked what

reasons there are for regarding it as a sign of affinity in the

* Ann. Mag. Nat. Hist. (6) xv. p. 178, pl. x. fig. 3a.

case of the Selenocosmiide, when we do not claim it to be a

sign of affinity between the Selenocosmiide and Jdiommata

and Trechona. ‘To this it must be replied that Zdiommata

and Trechona are separated from each other and from the

Selenocosmiidee by certain other characters which do not

admit of the genera presenting them being grouped in the

same category. But the genera of Selenocosmiide are, apart

from the presence of Wood-Mason’s organ, much alike in all

structural points; and this, coupled with the fact that they

inhabit the same geographical area, lends great weight to

the supposition that the mutual possession of Wood-Mason’s

organ may be regarded as an indication of relationship

between them.

In the introductory part of the paper the Autbor gives an account

of the characters, distribution, and literature of the Chalk Rock.

He poiuts out that the Chalk Rock fauna may be recognized at the

same level in Northern France, N.W. Germany, Saxony, Silesia, and

On the Reproduction of Wasps. By M. Paut Marewar*,

The results of my researches on the earth-burrowing wasps

(Vespa germanica, V. vulgaris) are as follows :—

Their nests, when they are fully formed, contain two sorts of cells,

the small and the large. The latter always constitute the lower

part of the wasp’s nest, for example the two lowest combs, while

the others make up the rest of the nest, namely the six to ten combs

superposed,

The large cells, which are only built by the workers during the

first fortnight of August, may, at an early period, receive indif-

ferently either females or males, the former being either queens or

very large workers, the latter always in small proportion ; after-

wards, at the beginning of September, these cells are entirely set

apart for the queens to such an extent that in October only queens

are to be found in them, the males being entirely excluded.

The small cells, on the contrary, from the time that the laying of

males has begun, contain indifferently up to the end of the season

either workers or males.

The proportion of males in the combs of small cells decreases

from below upwards, with this remarkable exception—that if there

be a mixed comb containing at one and the same time large and

small cells, the small cells of the mixed comb are influenced by the

proximity of the large cells, and contain but a very small quantity

of males.

The commencement of the period for laying males coincides

very nearly with the period of the appearance of the large cells and

takes place in the first fortnight of August. The curve which

represents their production rises suddenly in an almost vertical

manner to reach its maximum ; it then descends gradually, with or

without oscillations, to the end of the reproduction.

The queen takes a prominent part in this great production of

males, because the laying workers have already long since disap-

peared, whilst the young male larve are still to be found in great

numbers in the nests.

The queen has then (at least after the early days of September)

the power to determine with certainty the female sex of the eggs

which she lays in the large cells ; on the other hand, she lays indiffe-

rently either female or male eggs in the small cells.

One can only admit, in order to explain this remarkable fact, the

principle of the theory of Dzierzon, based upon the fecundation,

because if the production of males were due, for example, to some

influence of season, it is evident that the eggs laid at the same epoch

in the large cells would become male just as much as the others.

In order to interpret all the facts, this theory ought nevertheless,

in my opinion, to be modified, by allowing the intervention of

another factor than the will of the queen. We will admit, then,

* This work was carried out partly at the Entomological Station at

Paris. The experiments and observations on which the conclusions

arrived at are based will be published in detail later.

that after her first deposit (of eggs), exclusively those of workers,

which lasts uninterruptedly up to the end of July or the begin-

ning of August, the reflex which brings about the contraction of

the seminal receptacle at the moment of the laying of each egg

is no longer produced with the same energy, and that therefore

the eggs can be laid without being fecundated ; thence the almost

sudden appearance of males corresponding to the relative state of

inertia of the receptacle. Then it is that the workers building the

large cells give the queen a choice between two distinct classes of

alveoli; and she, stimulated by the presence of the large alveoli,

which seem to possess the power of rendering her reflexes more

energetic *, will concentrate from that time all her energies upon

them, and will only lay fecundated eggs and females. The

modification thus introduced into the theory is important, because

it replaces the voluntary act of the queen by a passive one. The

queen does not deposit males and females at will; but there comes

a time when she cannot do otherwise than deposit males, because of

the relative inertia of her receptacle. Among the bees the queen

appears to be always conscious f of this state of inertia, and when

she is subjected to it she will never lay in any other cell but that of

a male, unless there are none of them at her disposal (observations of

Drory). It is not the same among the wasps, which mark a less

perfect stage in the evolution of the phenomena relating to repro-

duction. With them the queen lays haphazard when she finds

herself over the small cells, and then, according as her receptacle

reacts or remains inactive, the deposit (of eggs) gives rise to patches

and streaks of workers or to patches and streaks of males, set

irregularly and without order one beside the other. If, on the other

hand, the queen finds herself over the large cells, stimulated by

their presence, she will only lay fecundated and female eggs.

It is very remarkable that, among the wasps, the large cells

(queen cells) are adapted to the state of activity of the receptacle,

whilst among the bees the large cells (male cells) are adapted to her

state of inertia.

Possibly further observations may bring into line other factors

not at present suspected, and will modify the theory which has just

been laid down. Its only value consists in its giving an accept-

able explanation of facts hitherto known and of those which I have

just set forth.

Laying of Workers.—This deposit is normal in August in the

nests which have their queens; it exists, however, in a relatively

small degree, and is not sufficient to account for the great rise in

(the number of) males ; then it diminishes and ceases completely

in normal nests in September and in October. The laying of

workers is exaggerated in an extraordinary degree by the simple

fact of the suppression of the queen or by her ceasing to lay,

* The queen in captivity shows a marked preference for the large cells.

+ The term conscious is not altogether correct, but it saves a peri-

phrasis ; it is rather a matter of adaptation, of pre-established harmony,

than of consciousness.

Miscellaneous. 183

It can be then provoked in workers in captivity to the extent

of obtaining one third fertile, whilst the workers of the same nest

in the company of the queen remain sterile. A nest of Vespa

vulgaris, in which the laying of eggs by the queen had been com-

pletely interrupted, yielded more than one half fertile workers,

whilst other normal nests, taken at the same time, yielded only

sterile workers.

It is evident that in these different cases the fecundity of the

workers can only be provoked by the absence of the young brood in

the nest and by the upsetting of the equilibrium of nutrition in

favour of the adults which results from it.

The production of fertile workers is independent of the bringing

up of the queens, contrary to the state of things which, according to

Huber, exists among bees. Their fecundity depends upon the

nutrition of the imago, and has so much the more chance to develop

itself because the worker is hatched after a shorter lapse of time

and is nourished in a manner much more intense.

The fecundity of the workers can only establish itself in a nest

when the food-collecting section of the community greatly exceeds

the larval, or, in other words, when the nutritive condition of the

colony reaches its climax, that is to say, in normal nests in the

month of August.—Comptes Rendus, t. cxxi. pp. 731-734.

Researches on the Structure, Organization, and Classification of the

Fossil Reptilia.—Part X. On the complete Skeleton of an Anomo-

dont Reptile (Aristodesmus Riitimeyeri, Wiedersheim), from the

Bunter Sandstone of Rethen, near Basel, giving new Evidence of

the Relation of the Anomodontia to the Monotremata. By H. G.

Seeter, F.R.S.

With the co-operation of the Trustees of the University Museum

of Basel and Professor Riitimeyer the author has examined the

fossil described by Dr. Robert Wiedershiem in 1878 as Labyrin-

thodon Riitimeyert. The bones are differently interpreted :—

The reputed humerus is the interclavicle.

The reputed scapula is the humerus.

The reputed supra-scapula is the left coracoid.

The reputed supra-scapula is the right scapula.

The reputed right and left coracoids are the pre-coracoid and

coracoid of the right side.

The reputed clavicles are the ribs.

Five digits are identified in place of four in 1878.

These osteological identifications are inconsistent with reference

of the type to the Labyrinthodontia. The author also examines the

relation of the Labyrinthodont type to existing Amphibia, and

regards the Labyrinthodont osteology as demonstrating closer rela-

tionship with Ichthyosauria and Anomodontia. The group is there-

fore regarded as reptilian, forming a branchiate division of the class.

184 Miscellaneous.

The fossil is referred to a new genus—Aristodesmus. It is iden-

tified as an Anomodont reptile chiefly on the basis of resemblances to

Procolophon and Pareiasaurus. It is shown not to be amammal by |

the large parietal foramen, the composite structure of the lower jaw,

and presence of the prefrontal bone. It, however, differs from

known Anomodonts in making a somewhat closer approximation to

Monotreme mammals than has hitherto been evident, and this

correspondence extends to successive segments of both the fore and

hind limbs.

The teeth are in sockets placed obliquely, with conical crowns

compressed to sharp lateral margins, and curved inward. The

proportions of the vertebral column are those of Hvhidna, though the

transverse processes are longer, as in Pareiasaurus. The ribs are

like those of a Monotreme, though the sacral ribs are longer. The

shoulder-girdle resembles that of Procolophon, and differs from all

other Anomodonts in the constituent bones being unanchylosed, and

in the precoracoid having a large anterior extension in advance of

the scapula. The sternum appears to have been unossified, as in

Crocodilia. The humerus is widely expanded at both extremities

and twisted, but does not show the peculiar lateral curvature seen

in Monotremes. The ulna gives no evidence of an olecranon process ;

it is larger than the radius, and appears to articulate with the

humerus. The pelvic bones are without acetabular or obturator

perforations, are not anchylosed together, and the ilium is not ex-

panded transversely. The hind limb is no longer than the fore

limb. The femur is more slender than the bone in Echidna. The

fibula is prolonged proximally beyond the stout tibia, round which

it may rotate. The proximal row of the tarsus is one large bone,

formed of the blended astragalus and os calcis.

In conclusion, the author argues that the points of structure are

so few in which Monotreme mammals make a closer approximation

to the higher mammals than is seen in this fossil and other Anomo-

dontia, that the Monotreme resemblances to fossil reptiles become

increased in importance, He believes that a group Theropsida might —

be made to include Monotremata and Anomodontia, the principal

differences (other than those of the skull) being that Monotremes

preserve the marsupial bones, the atlas vertebra, and certain cranial

sutures. Ornithorhynchus shows prefrontal and postfrontal bones,

and has the malar arch formed as in Anomodonts.

Aristodesmus, which suggests this link, is at present placed in the

Procolophonia, a group separated from its recent association with

Pareiasaurus, and restored to its original independence because it

has two occipital condyles, with the occipital plate vertical, and

without lateral vacuities, and has the shoulder-girdle distinct from

Pareiasauria in the separate precoracoid extending in advance of the

scapula.—From the Proceedings of the Royal Society.. (Communi-

XXVI.—Notes on the Anatomy of some Scorpions, and its

bearing on the Classification of the Order. By MAtcoutm

Lauriz, D.Sc., B.A., F.R.S.E., F.L.8., Professor of

Zoology in St. Mungo’s College, Glasgow.

[Plate IX.]

THE classification of the Scorpions has been based hitherto

entirely on external characters. While this method of

procedure is the most convenient for museum purposes,

where the preservation of the specimens intact is of import-

ance, it is very apt to lead to a system of classification

which does not express the true relationship of the forms.

That the results are not wholly satisfactory may be seen

by comparing the schemes proposed by Peters, Thorell,

Simon, Kraepelin, and Pocock. To cite a single example,

the members of section B of Thorell’s subfamily Pandinini

are distributed under two families by Simon, while Pocock

arranges them under two families which do not correspond

with those of Simon, and one of which contains two sub-

families. So far as I am aware the only attempt to apply

the internal structure of this group to their classification is

that of Ray Lankester *. He based his classification on two

sets of organs—the abdominal nerve-ganglia and the lamelle

of the lung-books. Owing to the small number of forms

which he examined, his scheme, which divides the group into

* Trans. Zool. Soc. vol. xi. p. 372.

Ann. & Mag. N. Hist. Ser. 6. Vol. xvii. 13

186 Dr. M. Laurie on the

two subfamilies and only three genera, is not altogether

satisfactory; nevertheless, it was an attempt in the right

direction, and one of his subfamilies agrees with the family of

the Buthide.

Having a considerable number of Scorpions in my_posses-

sion, it seemed worth while to investigate further on the lines

laid down by Professor Lankester, and see whether more

definite and satisfactory results could be attained. The

number of species at my command has, however, proved too

small to base any final conclusions on, though some points of

interest have come out.

While I have examined every point which seemed in the

smallest degree likely to yield any information, I only deal

with three in the present paper. This is due to the other

points, such as the entosternite, having given purely negative

results. ‘Two of the points I discuss are those dealt with by

Ray Lankester, and, in addition, I have taken the female

reproductive organs. My material having been collected origi-

nally with a view toembryological work, the number of males

was too small to give any results.

For my material I am indebted to Professor E. L. Mark,

of Harvard University, Mr. 8. F. Harmer, Cambridge,

Mr. Peringuey, of the Cape Town Museum, Professor Thom-

son, of Stellenbosch, and Mr. R. I. Pocock, of the British

Museum. I gladly take this opportunity of tendering my

sincerest thanks to all these gentlemen. For the correct

identification of my specimens—a point of importance for

this work—I am further indebted to Mr. Pocock.

In so far as any classificatory terms are used without

specifying in whose sense, they are taken from Mr. Pocock’s

classification *.

In conclusion, I may say that I would be very grateful for

further specimens to enable me to continue this research.

I. The Nervous System.

The nerve-cord in the meso- and metasomatic segments,

with which alone we have to do, consists of a pair of longi-

tudinal cords bearing ganglia at intervals. These ganglia

(Pl. IX. fig. 1) are seven in number and give off nerves on

each side to the segments to which they belong. A median

nerve has been described by Dufour ¢ and Lankester } passing

in a ventral direction from each ganglion. I have not found

this nerve in any of the forms I have dissected, and it seems

to me probable that previous observers have been misled by a

blood-vessel which passes ventrally between the two cords

close to each ganglion from the longitudinal vessel overlying

the nerve-cord. It is not easy to ‘separate this vessel from

the ganglion, but microscopic examination makes its nature

evident.

The most important part of the nerve-cord is that lying in

the mesosomatic and first metasomatic segments. Three pairs

of ganglia are present on this portion, and, according to

Lankester, their arrangement differs markedly in different

forms. In Androctonus (Prionurus) funestus *, Androctonus

occitanus T, Androctonus americanus t, and Androctonus hotten-

totus § the first two of these ganglia supply respectively the

third and fourth pairs of lung-books (eleventh and twelfth

segments), the third ganglion supplying the first meta-

somatic segment. ‘The segments anterior to the eleventh are

innervated from the prosomatic ganglion-mass. In Scorpio

italicus ||, Scorpio cyaneus |, Brotheas subnitens **, and two

species of Telegoniniff, on the other hand, the first two

ganglia supply the second and third lung-books respectively,

while the fourth pair is supplied by the third ganglion. In

these, therefore, the prosomatic ganglion supplies only the

segments as far back as the first pair of lung-books (seg-

ment 9).

In view of the great morphological importance of these

differences, I have devoted special attention to the point, and

have carefully dissected the nervous system in the following

forms :— Scorpio fulvipes, Opisthophthalmus capensis, Palam-

neus Thorellit, Opisthocentrus madagascariensis, Opistho-

centrus validus, Hormurus australusie, Vejovis sp., Kuscorpius

ttalicus, Broteochactas delicatus, Bothriurus bonariensis,

Buthus nigrolineatus, Parabuthus capensis, Uroplectes trian-

gulifer, and Centrurus, sp.

‘Lhe conclusion I have arrived at is as follows :—The first

ganglion may vary in position between the level of the second

188 Dr. M. Laurie on the

pair of lung-books (tenth segment), asin Parabuthus (fig. 1),

and a position forward in the second free segment, as in Scorpio

fulvipes (fig. 3). In Vejovis it is even further forward.

The nerve from it, however, passes always behind the

dorso-ventral muscle of the fourth mesosomatic (tenth) seg-

ment. About the level of this muscle it divides into two

branches, of which the anterior runs out to the body-wall,

while the posterior runs back to the lung-book in the fifth

mesosomatic (eleventh) segment.

The second ganglion may lie in the sixth mesosomatic

(twelfth) segment, as in Parabuthus (fig. 1), or it may lie

forward towards the front of the fifth mesosomatic (eleventh)

segment, as in Palamneus (fig. 2) and Vejovis. The

nerve from it runs behind the dorso-ventral muscle of the

fifth mesosomatic (eleventh) segment, and in front of that of

the twelfth segment, divides into two, and the posterior branch

goes to the last lung-book.

The third ganglion may lie well back in the first meta-

somatic (thirteenth) segment, as in Scorpio (fig. 3), or forward

in the last mesosomatic (twelfth) segment, as in Palamneus

(fig. 2). ‘The nerve from it runs either backward or forward,

according to the position of the ganglion and of the dorso-

ventral muscle of this segment, in front of which it passes.

I have never been able to trace it to the last pair of lung-

books, but it always goes to the muscles of the segment

(thirteenth) to which it belongs. It does not divide into two

branches as those in front of it do.

The four ganglia behind this supply each one of the meta-

somatic segments except the last ganglion, which innervates

the last two segments and the telson.

The nerves from the prosomatic ganglion to the first and

second lung-books have a course much like the nerves from

the first two ganglia. They pass respectively behind the

dorso-ventral muscles of the second mesosomatic (eighth) and

third mesosomatic (ninth) segments. Hach divides into two

branches—an anterior body-wall branch and a_ posterior

branch to the lung-books.

In Opisthophthalmus and probably in others, a fine nerve

runs longitudinally down the mesosoma on each side (fig. 4,

I.n.). It passes in each case under the body-wall branch of

the nerve and over the lung-book branch. It is connected

with each of the segmental nerves by a fine branch arising

from the nerve before it dividesinto two branches (segment 10),

from the body-wall branch after the division (segment 11),

or from the point of division of the nerye (segment 12). I

have as yet failed to trace this longitudinal nerve to its

termination at either end.

Examination of the nerve-cord shows, then, that we can

get no aid from it in classifying the Scorpions. The position

of the ganglia seems to vary quite independently of the

relations of the species to one another, as may be seen by

comparison of the figures, such unquestionably nearly allied

forms as Scorpio (fig. 3) and Palamneus (fig. 2) showing

great differences. On the other hand, the segments supplied

by each ganglion remain the same throughout. The position

of the ganglia might serve as a generic character, but is of no

greater value.

The varying position of the dorso-ventral muscle of the

first metasomatic (thirteenth) segment might also be useful

as a generic character, but here also we get considerable

differences in closely allied forms.

Il. The Reproductive Organs.

As nearly all my material was procured with the idea of

further elucidating the embryology of these forms, I have not.

had much opportunity of examining the male organs, and

will therefore postpone any account of them to some future

time. The general anatomy of the female organs is suffi-

ciently well known, and the only point of importance in which

the various forms differ is that of the structure of the egg,

and, in relation to this, the mode of formation of the embryo.

The two types of development have been described in detail

elsewhere, and seem to me to constitute a difference of very

considerable morphological importance.

In the first type of development * the egg is of consider-

able size, and contains a large quantity of yolk (fig. 7). It

passes at an early stage out of the follicle in which it is

formed and fertilized into the ovarian tube (fig. 8), in the

cavity of which it undergoes the greater part of its develop-

ment. ‘lwo embryonic membranes are formed round the

embryo, and it appears to depend entirely on the yolk for

nourishment. ‘This type occurs in all the Buthidee (Buthus,

Parabuthus, Uroplectes, Centrurus, Androctonus) which I

have examined, and also in Broteochactas, Bothriurus, Euscor-

pius, and Vejovis. It is probably the more primitive mode

of development, agreeing as it does in many respects with

other Arachnids. The egg of Vejovds is much smaller in

* V. Brauer, Zeitschr. wiss. Zool. vol. lvii.; Laurie, Quart. Journ.

Micr. Sci. vol. xxxi., &c.

190 ' Dr. M. Laurie on the

proportion than that of the other forms. In the one specimen

in my possession which contains partially developed embryos

there appears to be very little, if any, yolk. The embryos

develop in the ovarian tube, however, as in Huscorpius.

In the other type of development * the egg is very minute and

contains no yolk. Itis placed (fig. 6) at the distal end of a large

diverticulum of the ovarian tube, and the embryo as it grows

extends down and occupies the cavity of the diverticulum.

There appear to be no embryonic membranes, and the embryo

is nourished by consuming a solid cord of cells which ter-

minates the diverticulum. ‘This type of developmeut I have

found in Scorpio, Heterometrus, Palamneus, Opisthophthalmus,

Onpisthocentrus, and Hormurus. Thus, so far as my observa-

tions go, it is characteristic of the family Scorpionide, but

1 have not had specimens from the subfamilies Diplocentrini,

Hemiscorpiini, or Urodacini. This is the more to be re-

eretted as we shall see that there is some reason to doubt the

close alliance of, at all events, the Diplocentrini with the other

Scorpionidee.

An additional mode of nourishment of the embryo in the

form of two outgrowths from the head, which probably absorb

fluid from the surrounding tissues, occurs in Opisthoph-

thalmus fT. .

A structure which I have not seen fully described, and the

function of which is unknown to me, occurs in all the

Scorpionide and Ischnurides which I have examined, but

seems to be wanting in the Buthide. It consists of a pair of

hollow cylindrical processes projecting back into the abdomen

from the posterior side of the diaphragm between the pro-

soma and the mesosoma. In sections it is seen to be com-

posed of two layers of cells separated by a thick non-cellular

layer. The outer cell-layer appears to be continuous with

the diaphragm, while the inner one comes into close con-

nexion with the capsule of flattened cells surrounding the coxal

gland. It is possible that the cavity of this diverticulum is

in communication with the lumen of the coxal gland, in which

case it is a portion of the ceelome. I have not been able to

satisty myself on this point, however.

Ill. Lhe Lung-books.

These are more available for systematic purposes than the

preceding structures, as it is possible, by making an incision

between two of the sternites, to extract the lung-book without

injury to the external appearance of the specimen. ‘Treat-

ment for fifteen minutes with hot dilute caustic soda makes

the structure more distinct by removing the organic matter.

The anatomy of these structures is sufficiently well known,

and, as it seems to be constant throughout the group, need

not concern us here. The shape of the lamelle varies too

much in the different parts of the lung-book to be of any

service. Lankester * used the surface-markings of the

lamelle in his classification, and distinguishes two types.

In one of these the whole of the upper surface of each

lamella is covered with small pillar-like structures, which

serve to maintain a space for the air between each pair

of lamelle. Berteaux ¢ has shown that these rods or pillars

are in Scorpio indicus of two kinds. Those round the

margin of attachment are smaller than the others, and their

upper ends fuse to the lower surface of the lamella above.

The larger pillars which occupy the centre and free border of

the lamelle do not fuse to the superjacent lamella, but fre-

quently divide at the top, and may form arcades by uniting

with adjoining pillars. ‘These two regions of the lamella are

usually quite distinct from each other and easily made out.

In Luscorpius flavicaudis according to Berteaux the rods

nowhere unite with the adjoining lamella. ‘lhe two areas on

the surface of the lamella are nevertheless quite distinct, at

all events, in Huscorpius ttalicus.

In the second type of lamella the area occupied in the first

type by the larger pillars is covered by a network of chitinous

ridges, the meshes of which are subdivided by smaller ridges.

Pillars are entirely wanting over this region, but towards the

sides they begin to appear among the ridges, and finally

replace the ridges entirely.

Berteaux has described a further difference in various

forms in the structure of the free edge of the lamella. In

lamelle of the first type the edge may be furnished with

sharp spines (fig. 9), a condition which he describes in

Scorpio, or the spines may divide at their free ends, and,

uniting with each other, form a regular arcade (fig. 10), an

arrangement which occurs in Huscorpius.

In the second type the network of ridges is present on

both surfaces of the lamella, the larger rndges being con-

tinuous over the edge, and the edges are devoid of spines

(fig. 11).

192 Dr. M. Laurie on the

We have thus three types of structure for the lamella,

which we may term the spinous, arcade, and reticulate forms.

The spinous type occurs in Scorpio, Heterometrus, Opisth-

ophthalmus, Palamneus, Opisthocentrus, Hormurus, and

Urodacus among the Scorpionide; in Scorpiops, Vejovis,

Hadrurus, and Broteochactas among the luride ; and in the

only member of the Bothriuride which I have seen, namely

Bothriurus. From its wide range this type of lamella is

probably the most primitive.

The arcade type occurs in Diplocentrus and Nebo among

the Scorpionide, and in Jurus, Caraboctonus, and Huscorpius

among the luridee.

The reticulate type occurs in Buthus, Parabuthus, Uro-

plectes, and Centrurus, all belonging to the Buthide.

The morphological value of the lamelle is probably less

than that of the development.

The following table summarizes the two sets of facts and

gives a list of the species I have examined :—

The number of forms examined is far too small to base

deductions on with any certainty, and to classify on the

ground of these two structures alone would be almost certain

to lead to a wrong conclusion. ‘The results seem, however,

to suggest the following rearrangement :—

ta)

Anatomy of some Scorpions. 193

(1) Scorpio, Heterometrus, Opisthophthalmus, Palamneus,

Opisthocentrus, and Hormurus remain associated as

one group on the ground of their embryology.

All the rest have the Euscorpius type ot develop-

ment, and can be divided by their lung-books.

(2) A second group is formed by Scorpiops, Vejovis, Ha-

drurus, Broteochactas, and Bothriurus, which have

“spinous” lung-books. Vejovis may have to be

isolated on account of the difference in development.

(8) Diplocentrus, Nebo, lurus, and EHuscorpius agree in

having the areade type of lung-book.

(4) Buthus, Parabuthus, Uroplectes, and Centrurus have

the reticulate type.

The first and last of these groups are in perfect accord, so

far as they go, with Pocock’s classification ; the others agree

less perfectly. The separation of Euscorpius from Broteo-

chactas is not improbable, and gets over the difficulty of the

geographical distribution of the Chactini; but the association

of it with Jurus, and still more with D¢plocentrus and Nebo,

is less plausible, and it is much to be regretted that I have

had no opportunity of examining the ovaries of these last two

genera.

The bringing together of Bothriurus and Hadrurus is not

unnatural. Pocock saysof the Bothriuridee :—*‘ The Scorpions

of this group seem to be little more than an exaggeration of

some of the American members of the Lurini, for some of them

show many points of resemblance to Caraboctonus and Ha-

drurus.” Unfortunately the two forms here named do not,

according to the lung-books, seem to be closely related.

Kraepelin’s * classification needs less alteration, inasmuch

as he unites the Iurideé and fScorpionide of Pocock as one

family. His subfamilies are practically the same.

How far these internal characters will agree with the ex-

ternal ones when these last are re-examined is a question

which I think it better to leave to those who have had

experience in discriminating the minute points of external

difference.

Diagnosis.—Entalophoride in which the zocecia are short

Type species: Haploecia straminea (Phillips), 1829.

Affinities— This genus is proposed for some species which

differ trom Entalophora and Spiropora by having short

hexagonal zocecia instead of long regularly tubular ones.

As the aperture is not truly terminal and is somewhat con-

tracted, the zocecia show a certain resemblance to those

of the Cheilostomata; if the ordinarily accepted definitions

of Cheilostomata and Cyclostomata be rigidly applied the

members of this genus ought to enter the former order. Some

of the species have been included in Melicertites, a genus of

which the type species is very uncertain. ‘These forms cannot,

however, enter Melicertites, as accepted by Pergens, whose

use of this name may be conveniently accepted.

Diagnosis.—Zoarium tufted, loose, and irregular; branches

of medium thickness.

Zoecia in regular, horizontal, closely adjoining series,

usually hexagonal and bisymmetrical, but variations in growth-

pressure render some irregularly polygonal. Aperture trans-

versely elliptical. Peristomes slightly raised. Front wall

punctate.

Distribution. — England: Inferior Oolite — Cornbrash.

Foreign: Bajocian, Germany; Bathonian, France.

2. Haploecia irregularis, sp. n.

Diagnosis.—Zoarium composed of small cylindrical stems,

which dichotomize irregularly and usually at short intervals.

Zoecia usually hexagonal, but occasionally heptagonal or

pentagonal, often irregular, irregularly quincuncial in arrange-

ment. Apertures large, circular, or, when worn, transversely

elongate. Front wall coarsely punctate.

Distribution.—British : Great Oolite, Ancliff, near Bath ;

Lincolnshire Limestone, Stamford. Foreign: Bathonian,

Normandy.

Affinities. —This species is separated from the former one

by the irregularly quincuncial arrangement of the zocecia.

Genus 4. CERIOCAVA.

Diagnosis.—Entalophoride in which the zoarium consists

of thick massive stems, each of which is composed of a large

number of zocecia. The zocecia are funnel-shaped. ‘The

apertures crowded. The peristomes flush. The axis of the

zoarium consists of fine zocecia, densely packed. The outer

zone consists of zocecia which are usually reflexed and of

much greater diameter.

Diagnosis.—Zoarium dendroid, erect, growing in thick,

solid branches, which anastomose occasionally. The branches

are regularly cylindrical, or compressed (form dumetosa). ‘The

surface is level, or raised into pustules (var. pustulata).

Zoecia thin-walled ; diaphragms numerous. Aborted

zocecia scattered irregularly through the zoarium.

Distribution. — England: Great Oolite and Cornbrash.

Foreign: Bathonian, France.

2. Ceriocava laxata, sp. n.

Diagnosis.—Zoarium with branches fairly regularly cylin-

drical.

Peristomes irregular in shape, size, and arrangement.

Number of zocecia in a branch comparatively limited. The

central axis consists of few zocecia, irregularly and loosely

arranged.

Distribution.—Inferior Oolite, Leckhampton.

A ffinities.—This species is most nearly allied to Certocava

corymbosa (Lamx.). The differences can be clearly seen in a

longitudinal section. The central axis has far fewer zocecia,

and these are not so tightly packed. It is not easy to

separate the specimens of the two species by the external

characters; but the apertures in C. corymbosa are more regular

than in C. laxata.

the fringe.

Genus SicuLopgs, H.-S.

Siculodes argentalis, W1k., var. tuberosalis, nov.

Differs from typical argentalis in the shape of the marginal

brown blotch, which, instead of being sinuous on the inner

edge, is concave and well defined and irregularly oval in

shape; the oval apical blotch, instead of being filled up with

black, is shining white, with the upper edge alone black.

The brown blotch probably varies locally; Mr. Meyrick

(Trans. Ent. Soc. 1894, p. 479) remarks that the Sambawa

examples have it narrower than the Bornean, but he does

not refer to any difference in the shape and contour.

This present variety is from the Khasias.

Study of Madreporarian Types of Corals. 219

XXX.—WMicroscopic and Systematic Study of Madreporarian

Types of Corals. By Marta M. Oativig, D.Se.*

In the first part of this paper the author gives the results of

her microscopic investigations on the structure of the skeleton

in a number of typical Madreporaria.

Detailed microscopic study of the surface of the septum

showed small scales lying above and against one another,

somewhat like the slates of a roof, and consisting solely of

fine, parallel-placed, or diverging aragonite fibres. Besides

these calcareous scales, ectodermal cells (calicoblasts) could

still be observed in several cases attached to the surfaces of

septa in fresh specimens. Heider and one or two other

authors have already mentioned the frequent occurrence of

organic polypal remnants on skeletal surfaces.

The scales observed by the author were found to agree

precisely in shape and size with the calicoblasts, and to show

various transitional stages from the organic cell to the calcified.

It follows from this that the skeleton of Madreporaria takes

its origin from an actual calcification of the calicoblasts, and

not, as Koch thought, by a secretion laid down outside the

cells. The author found further that the calcareous scales

were arranged in extremely thin lamelle, and that the fibro-

crystalline deposit was similarly oriented in successive

lamella.

The stages in the process of skeleton-building may be thus

generally stated :—

(1) Caleareous deposit is laid down within individual

calicoblasts of the ectoderm. At the same time new ecto-

dermal cells are formed next the mesogloea, and these which

are undergoing calcification become loose external layers of

partly calcareous, partly organic tissue.

(2) Fibro-crystalline groups of aragonite are built up in

the individual cells, and the cell-walls shrivel. Thus a

connected calcareous lamella is formed, which is ultimately

incorporated with the skeleton.

(3) Changes of disintegration and crystallization still con-

tinue after the cell-lamella has severed living contact with

the polyp. The disintegration of organic cell-remnants

produces various flecks and bands, usually carbonaceous, in

the midst of the crystalline deposit. These afford the

220 Miss M. M. Ogilvie—Microscopic and Systematic

explanation of the so-called “dark streaks” and other

appearances in the skeleton.

The finer structure of the septa will be readily understood

when it is remembered that the septa are formed within radial

invaginations of the aboral body-wall of the polyp. The

septal surfaces are practically casts of the two flaps of a septal

invagination. When the flaps are smooth the calcareous

lamellz are also smooth ; but, according to the author’s obser-

vations, that is seldom the case in recent Madreporaria.

Usually the septal flaps are pitted and goffered, resembling

the pleated muscular flaps of the mesenteries, and the septal

surfaces are correspondingly granulated and fluted. The

author has found that in all cases the calcified calicoblasts of

successive lamelle are grouped around definite centres of

deposit situated in the median plane—corresponding to the

growing edge—ot the septum. Subsequently the individual

groups of calicoblasts assume the form of radiating bunches

of fibro-crystalline aragonite, passing outwards from the

original centre of deposit in the median plane to the surface

of the septum. The author has given the name of “fascicles”

to these fibro-crystalline “ bunches,” and has demonstrated

the relation which they bear to the external sculpturing

observed on lateral septal surfaces. The emergence of a

Jascicle at the surface gives rise toa granulation. The fascicles

are, however, of varied size; if large, one fascicle usually

corresponds to one granulation, if small, a number of fascicles

may, in the course of septal thickening, coalesce to form a

broad nodular granulation. The size of individual fascicles

depends on the original closeness of the “ centres of calcifica-

tion” at the septal edges.

The trabecula (=“‘poutrelle,” Edw. & H.) of a “perforate”

septum is composed of symmetrical groups of fascicles placed

in vertical series. The author has further found that those

septa described by Edwards and Haime as “ imperforate and

leaf-like ” are also composed of trabecule. But the individual

parts of these trabecule have an opposite patr of fascicles,

instead of an indefinite number. ‘The majority of Astreid

genera have septa in which both kinds of trabecule occur.

The author apples the term ‘simple trabecula” to a

trabecula made up of successive pairs of fascicles, as the axis

of deposit is in part or wholly common to the opposite

fascicles, and the term “ compound trabecula’’ to one made

up of successive groups of fascicles. In the former case the

tibro-crystalline deposit may be said to be bilaterally sym-

metrical in the opposite halves of a septum ; in the latter the

fibro-crystalline deposit is radially symmetrical around ideal

Study of Madreporarian Types of Corals. 221

trabecular axes in the median septal plane. Each member of

a successive series of fascicle “ pairs” or “ groups” in a

trabecula is called by the author a trabecular part ( Trabekel-

guied). The “fascicle”” may be regarded as the structural

unit of the coral-skeleton. Two or more fascicles combine to

build up a “trabecular part.” And the differences in the

relative arrangement of trabecular parts determine the endless

varieties of skeletal form within the Madreporaria.

The author has subjected the following typical genera to a

detailed microscopic investigation :—Galaxea, Mussa, Heli-

astra, Gontastrea, Montlivaltia, Thecosmilia; then Fungia,

Siderastrea, Lophoseris; further, Hupsammia, Haplarea ;

and, lastly, Turbinaria, Actinacis, Madrepora, and Porites.

This research enables the author to state that different types

of septal structure are characteristic of different groups of

Madreporaria. he differences relate to the microscopic

structure of the trabecule and to the arrangement of trabecule

in the plane of a septum. It is impossible here to do more

than indicate the line of research. Turbinaria is an example

of an extremely simple structural type. The component

trabecule are small, uniform in size, and directed all in the

same way, obliquely or almost horizontally inwards from the

periphery of the septum to the inner edge. The fascicles are

paired, and their axes never bend out of the median septal

plane. Ga/axea has a septum whose trabecule bend right

and left from a definite area of divergence in the septal plane.

The individual trabecule are large, vary in size, and the axes

of the paired fascicles bend out of the median plane towards

the opposite surfaces of a septum. The septum of Mussa is

composed of a number of broad ridges, elliptical in section

and ending at the upper edge of the septum in broad “ spini-

form teeth.” The author shows that each “ spiniform tooth ”

is itself finely serrated, and that the serree represent apices of

trabeculae. In short, a single broad ridge of the Mussa septum

as the precise homologue of the complete Galaxea septum, being

built up of fan-shaped groups of trabecule diverging right

and left from the middle area of a ridge. Again, Hungia has,

like Mussa, a septum composed of a number of ridges; but

the trabecule: in each ridge have a course almost parallel with

one another. The emergent fascicles are thus so close that

coalescence inevitably takes place; the soft parts of the polyp

clothing the ridge are pushed ontwards at the prominent

middle part of the ridge, and readily give rise to synapticular

union between septa. Further reference to this part of the

work must be omitted here.

‘he author observed in sections of recent types that a larger

222 Miss M. M. Ogilvie—Miecroscopic and Systematic

amount of organic cell-material was usually present near the

median plane of the septum than towards the lateral surfaces.

This she believes may be attributed to the greater rapidity of

the calcareous secretion and the less complete calcification of

the calicoblasts present at the doubled upper edges of septal

invaginations. In fossil material secondary changes render

this central part of the septum more or less conspicuous on

account of the breaking down of organic products, or some-

times the complete replacement by infiltrated salts. The

author strongly contends that there is no basis for the assump-

tion of a “wrimary septum”’ in the middle plane of a septum

in the sense at present accepted by most palxontologists. On

the contrary, the author’s sections show that the fibro-crystal-

line structure of the septum its the same throughout its whole

thickness, essentially that of a double system of thin calcareous

lamelle, either smooth or fluted, and corresponding to a

deposit from opposite flaps of an invagination.

The author’s investigations afford many new microscopic

facts of structure, testifying that the growth in height of the

polyp is accomplished at certain growth-periods, between

which pauses ensue. During each growth-period a varying

number of the calcareous lamelle, ‘ growth-lamelle,” are

laid down, and these always appear in intimate union with

one another. Again, regular curves or lines of growth are

evident on the septal surfaces, marking the intervals between

successive growth-periods. The space between two growth-

curves or lines on the septal surface represents the part of the

septum built up in one growth-period, and it has been called

by the author a septal growth-segment. An important obser-

vation is that the extra length added to a single trabecula in

one growth-period is ¢nvartably one trabecular part; this

length varies in the trabecule of one and the same septum,

being greatest at the exsert portions near the wall.

Granulations mark tlhe surfaces of trabecular parts. Ed-

wards and Haime applied the term “‘ synapticula”’ to the inter-

septal bars in Mungia and its allies, and described the synap-

ticula as formed by coalescence of granulations from opposite

surfaces of neighbouring septa. The author demonstrates

that in Fungia the granulations seldom meet across interseptal

loculi; but a continuous calcareous deposit is formed in a

special invagination of the interseptal parts of the aboral

body-wall. ‘Together with a number of observations on other

synapticulate types, this has led the author to accept a distine-

tion made by Pratz, and hitherto discredited in the literature.

Pratz proved that the tossil Fungid subfamily of Thamnas-

treine had synapticule formed by coalescence of granulations,

Study of Madreporarian Types of Corals. 223

and these he called “ pseudo-synapticule.” The name of

“true synapticule ” he limited to such as were formed around

new centres of deposit out of the septal plane ; these he found

in Siderastreea, but did not farther examine typical genera

belonging to the families Fungine and Lophoserine. The

author’s results are that pseudo-synapticule occur not only in

Thamnastreine, but also in the Funginz, Lophoserine, and

occasionally in Astreide and EKupsammide; while ¢rue

synapticule occur chiefly in Fungine and Eupsammide,

rarely in Lophoserina:, and never in Astreide. The author

regards true synapticule as basal structures representing

modified dissepiments. ‘The advantage of synapticule to the

polyp is that they afford a basal support over which the fleshy

parts and mesenterial loculi may bend and be continued to

some depth. The author, in pointing this out, refers to the

analogy of the internal canaliculate visceral system thus pro-

duced with the external canaliculate system attained by a

porous coenenchyme in ‘ Perforate” colonies. At the same

time she thoroughly disagrees with the prevailing opinion that

the synapticulate types have any nearer relationship with

Madrepora, Porites, &e., since the skeletal parts show many

important differences of structure; neither is the ‘ porous

ccenenchyme ” in any way homologous with the synapticulate

calyx.

No essential difference is presented between septa, coste,

and wall in respect of their microscopic structure ; and the

author found it also for other reasons practical to distinguish

in her work the septa and cost under the inclusive name of

radial structures, the wall, on the other hand, as a tanyential

structure. Dissepiments, tabula, true synapticule, and certain

kinds of columella are regarded as basal structures.

The microscopic structure of dissepiments and tabule ts

demonstrated by the author to be thesame. Both are composed

of a series of calcareous growth-lamelle laid down from one

surface only of the aboral body-wall of the polyp. The fibro-

crystalline deposit is therefore perpendicular to the plane of

contact between polyp and skeleton. The distance from one

platform of dissepiments to the next above coincides in all

typical Astreeids with the interval between two growth-lines

on the septal surface. It may be deduced from this that the

polyp lays down a new basal support for itself at the close of

each growth-period. The solid calcareous deposit (usually

called ‘‘ stereoplasm” or “ endotheca”’?) at the base of the

short simple calyces of most Turbinolids has the same micro-

scopic structure as tabule or dissepiments, differing from

224 Miss M. M. Ogilvie—Microscopic and Systematic

them only in the fact that the new groups of growth-lamellee

are always closely opposed to the foregoing.

The “ columellar” or “ pseudocolumellar” area of recent

Madreporaria is explained by the author as the morphological

equivalent of the “tabulate” area in most Paleozoic Madre-

poraria. The styliform or fasciculate “true” columella of

Turbinolia and its allies proves itself to be, structurally con-

sidered, a basal deposit, and is merely an upwardly arched or

entwined modification of the tabula. The ‘ pseudocolumella”

is, as already known, a mixed structure in which septal teeth

or outgrowths unite with irregularly distributed basal deposit.

It finds its antetype readily in the occasional warping of the

septal spines or inner ends within the tabulate area of certain

Paleozoic genera. The “ lamellar” columella is of especial

interest ; the author looks upon it as the remnant of a retro-

grade ‘main septum,” affording therefore an important

phylogenetic link between so-called “tetrameral” and “radial”

symmetry of the septa wherever it occurs.

Considerable differences are at present found in Madre-

porarian literature in the use of the terms “theca” and

“ epitheca.” The author accepts Heider and Ortmann’s terms

“¢ nseudotheca”’ for a wall formed by lateral thickening of the

septa, and “‘ eutheca,” or simply theca, for a wall in which

independent centres of deposit are developed. Ortmann’s

suborders of Madreporaria, Kuthecalia, Pseudothecalia, Athe-

calia are, however, believed by the author to be based on an

erroneous principle, since all types with a porous wall are

placed among Athecalia. Porosity is looked upon by the

author as a secondary feature, the porous wall can be demon-

strated to be the morphological equivalent either of pseudo-

theca or of eutheca. A still more serious objection to these

suborders is the fact that not all Turbinolids possess an

eutheca; neither do al] Astreids possess a pseudotheca as

Ortmann means, but cases occur in both those families where

the only peripheral support is afforded by the epitheca. The

author 1s inclined to think this was the primitive form of the

Madreporarian calyx, and to look upon both theca and

pseudotheca as later modifications associated with retrogres-

sion of the epitheca, greater prominence and rapid growth of

the septa, and very often with the processes of vegetative

budding.

Certain coenenchymatous colonies, Madrepora, Turbinaria,

&c., have been shown by the author to have thecal and septal

structure like the Turbinolids ; further absence of basal struc-

tures in the calyx other than columella. This throws a new

light on the relationship of these types, and brings them along

with the Oculinide and Pocilloporide into a very natural

affinity with the Turbinolide. The ccenenchyme of these

colonies is treated by the author as an elaboration of a primi-

tive extra-calycinal deposit around individual polyps. Bourne,

in one of his papers, suggests the possibility of coenenchyme

being epithecate in certain of these types.

In order to elucidate the ‘‘ costate ” portions of Astraid and

Fungid colonies the author demonstrates the exact homology

of skeletal parts in the calyces of ancient Cyathophyllids and

of recent Astreids and Fungids. The psendotheca which

appeared in Acervularia and other Cyathophyllid types

marked out an inner from an outer area of the calyx and

septa. ‘The exact counterpart of this is found in the type-

genus of the Astreide, Heliastrea. In it, however, only the

inner part is called calyee, while the outer area is spoken of as

“ costate ”’—extra-calicinal—area. It is on this outer area

that the so-called “ Randplatte ” (which the author translates

as ‘‘edge-zone ’’) is supported in the living polyp, and the

author takes it that the typical edge-zone has mesenteries and

mesenterial loculi simply because it was originally an inherent

part of the polyp. It is clear that such costate parts in

Astreid colonies have an entirely different evolutionary

history from the coenenchyme in the Pocilloporide &c., where

no edge-zone surrounds the polyp. The author traces back

this difference in recent colonial types to a difference already

well-marked in Silurian Madreporaria—viz. the difference

between the calyces of a ee Cyathophyllid and a typical

Zaphrentid respectively. In the former a broad calycinal

outer zone with dissepimental base surrounds an inner tabulate

area; in the latter there is no such outer zone or the very

slightest indication of it.

The author found that the families of Edwards and Haime’s

classification must undergo considerable changes ; she limits

herself here to one or two of the most important changes sug-

gested by her on the basis of microscopic septal structure and

generally of the morphology of the skeleton. The family of

Astreide, Ki. & H., hitherto included two main subfamilies,

the Astraine and Eusmiline. The former is made by the

author the sole representative of Astreeide, while the latter is

entirely broken up. The genera Yrochosmilia, Placosmilia,

and their allies are referred to the family of Turbinolide ; the

genera Riipidogyra, Pectinia, Dendrogyra, Huphyllia, and a

large number of fossil genera are placed in a new family,

Amphiastreeidz, erected by the author. ‘The Mesozoic repre-

sentatives of this new family are proved to be direct colony-

building descendants ot Paleozoic Zaphrentids, while the

226 Miss M. M. Ogilvie—Microscopic and Systematic

Turbinolidz are looked upon as simple corals descended from

the same Paleozoic family. The Stylina group of Kusmiline,

E. & H., are placed in the neighbourhood of the Astreeide

and Amphiastreide as an intermediate family, Stylinide.

Galazea is regarded as a near ally of the Stylinide ; in spite

of its somewhat aberrant features the author ranks it provi-

sionally within this family.

Edwards and Haime’s group of Madreporaria Perforata is

also broken up by the author. The Eupsammide show

undoubted affinity with the Fungide, and both these families,

together with the Astreide and Stylinide, are shown to have

derived their structural features from leading Paleozoic types

belonging to the family of Cyathophyllide. In all of them

the septum reaches a high degree of differentiation in its

trabecular structure on lines already introduced in various of

the more advanced Paleozoic types. The Madreporide

(Turbinarine, E. & H., and Madreporine, HE. & H.) are

placed in the neighbourhood of Pocilloporidee and Oculinidee ;

their simple septal structure agrees with the primitive types

of septum presented by Paleozoic Zaphrentids and their

allies. The Poritide, although having certain features in

common with the Madreporide, differ essentially in septal

structure, and are regarded as a group of Madreporaria which

branched off at a very early age from the main ancestral stem

of Zaphrentide, and followed an independent line of deve-

lopment.

The author’s results bear inevitably to the conclusion that

the suborder Madreporaria Rugosa erected by Edwards and

Haime draws an entirely artificial barrier between Paleozoic

Madreporaria and the younger suborders Madreporaria A porosa

and Perforata, Ed. & H. In the second part of the present

paper the author annuls all three suborders, and follows out

the evolution of Madreporaria in the light of the general

morphological results arrived at in the first part of the paper.

Heckel’s terms of “ Tetracoralla” for the Madreporaria

Rugosa and “ Hexacoralla” for the Madreporaria A porosa and

Perforata only gave a stronger expression to Edwards and

Haime’s convention of tetrameral and hexameral symmetry

of the septa. And although several authors have from time

to time pointed out the inappropriateness of erecting sub-

divisions on the feature of septal symmetry, nothing tarther

has been done. Even now in current literature one may find

the term Lugosa='Tetracoralla set in contradistinction to

Madreporaria= Hexacoralla!

From the standpoint attained by her own investigations

the author then traces the series of changes which appeared

Study of Madreporarian Types of Corals. 227

within the group of Madreporaria during the course of the

geologic ages. Some of the more important and general of

these evolutionary changes may be shortly enumerated :—

(1) Tabule became modified centrally as columella and

pseudocolumella, more seldom became vesicular.

(2) Instead of one to four basal pits (fossule) for the recep-

tion of specialized reproductive mesenterial filaments, the

whole base of the calyx became deepened, usually around the

axial columella or pseudocolumella.

(5) Septa became more prominent and exsert in growth ;

their structure became more elaborate, their surfaces fluted

and richly granulated, their edges knobbed, toothed, serrated,

spined.

(4) The “rugose epitheca”’ became tardy in growth, and

was replaced functionally by a theca or pseudotheca.

(5) Vegetative increase was facilitated by the specialization

of an “ edge-zone”’ around the polyp (represented by the

“ costate”” portion of a calyx, or its ancient homologue, the

peripheral “ dissepimental zone” of Cyathophyllids).

(6) The “pinnate insertion” of septa demonstrated by

Kunth in primitive corals became gradually a feature of

embryonic calyces, and then vanished; but the embryonic

mesenteries appear in recent types in the same ‘“ tetrameral ”’

order as the septa did in the mature calyces of primitive types.

The disappearance of ‘‘ pinnate insertion’ asa generic feature

did not necessarily entail the abandonment of a tetrameral,

more properly said bilateral, arrangement of the septa. It

induced mainly the hastening of septal insertion, the relative

position being often retained, even in adult forms*, Again,

many recent types said to have radial symmetry of septa in

adult calyces have well-marked bilateral symmetry in the

young individual.

All the above changes indicate, in the author’s opinion,

merely various lines of adaptivity, correlative with one great

leading change in the living polyp—an increase tn the number

of gonad-bearing mesenterries and in the musculature of the

mesentertes, resulting in improved powers of self-preservation

and of reproduction.

The evolution of recent Madreporarian families from primi-

tive types hinges round the gradual incoming of that main

change. ‘lhe general law of the hastening of the develop-

mental stages in the individual worked with this change, and

* Various observations bearing out this statement have been made by

the author on Mesozoic corals. ‘These are fully described in the author’s

“ Monograph of the Upper Jurassic Stramberg Corals,” at present being

published in the ‘ Palaontologische Mittheilungen ’ (Koch, Stuttgart).

228 Dr. A. Giinther on Two new

the pinnate insertion of septal pairs became more and more

modified to a cyclical system of insertion. The author points

out in favour of this view how the untoward circumstances

for coral existence which prevailed in Europe during the

Upper Carboniferous, Permian, ‘Triassic, and Liassic ages

may have given a widespread impulse towards the carrying

out and confirmation of the main evolutionary change as

above stated. The change, however, has been ever since in

progress. The author traces its constant working within the

family of Astreide, its influence on Kupsammide and Oculi-

nid, and so on.

There is therefore, in the author’s opinion, no greater

fallacy than the idea that some universal change took place

amongst Madreporaria at the end of Paleozoic time and before

the mid-Triassic era. One and the same line of evolution

may be detected making its way in the group of Madrepo-

raria. Precocity in advance was shown by the Paleozoic

Cyathophyllids ; hence the high differentiation of Astreids,

Eupsammids, and Fungids as early as Mesozoic ages. On

the other hand, the Paleozoic Zaphrentidsand their descendants

in Mesozoic times were remarkably backward in advance, and

it is among their recent representatives that primitive struc-

tures and forms are chiefly upheld. Naturally retrogression

and atavism is shown in various degree in all families, in

none more so than in the Turbinolids, the family most closely

allied with the ancient Zaphrentids.

The author draws up a new classificatory system of Madre-

poraria into a number of independent families of equal rank.

‘These are based on the study of skeletal structures, known

facts of anatomy, and phylogenetic relationships. She

arranges the families, according to the lines of descent demon-

strated in the present paper, as follows :—

Zaphrentoidean Families: Gaphrentide, Amphiastreide,

Turbinolide, Stylinide, Oculinide, Pocilloporide, Madre-

poride, Poritide.

Cyathophylloidean Families: Cyathophyllide, Astreide,

Fungide, Kupsammide.

XXXI.—Descriptions of Two new Species of Snakes from

Sarawak. By Dr. A. GUNTHER.

In a collection of Snakes which I received recently from

Mr. C. Hose there were two species which appear to be

undescribed.

Species of Snakes from Sarawak. 229

Calamaria Hose, sp. n.

Moderately slender in habit; head broad, depressed; eye

very small. Scales in 13 rows; ventrals 188; subcaudals 19.

Upper labials 5. A minute preocular in the antero-inferior

corner of the orbit, and a very small postocular. The vertical

shield is very broad, at least four times as broad as the supra-

ocular. The symphysial is in direct contact with the men-

talia. ‘T'wo transverse rows of scales before the first ventral

seute. Upper parts pinkish, with black cross-bars, which are

narrower than the interspaces between them and contracted on

the sides ; there are eighteen of these cross-bars on the trunk

and three on the tail. The scales within the pink parts of

the body are bordered and speckled with blackish. Head

brownish above, this colour extending downwards on the

sides in the form of two ill-defined oblique bands. ‘Tail with

a blackish longitudinal stripe along each series of scales.

Lower parts white, with a few scattered blackish spots ; sub-

caudals blackish.

One specimen, 14 inches long (of which the tail takes

14 inch), was discovered by Mr. Hose on the Entoyut River.

Geophis albonuchalis, sp. n.

Head narrow, snout pointed, body moderately stout, tail

tapered ; eye very small. Scales in 15 rows, without apical

groove. Ventrals 141; anal entire; subcaudals 43. Ante-

rior frontals triangular, small, only one fourth the size of

posterior, which enter the orbit. Vertical very large and

broad, broader than long, reaching from one orbital margin

across to the other, and pressing back the supraocular to the

postero-superior angle of the orbit. Occipitals as long as the

anterior shields together, and forming a long suture with the

fitth upper labial. ‘Two nasals. Loreal and anteocular con-

fluent into one long shield. A minute postocular. Upper

labials six, of which the third and fourth enter the orbit.

Symphysial in direct contact with the mentalia, which are

considerably longer than the post-mentalia. Six lower labials,

the fifth long and narrow.

Deep black, with a broad pure white collar, which covers

half ot the occipitals and the neck.

One specimen, 94 inches long (of which the tail takes

18 inch), was discovered by Mr. Hose at Baram.

230 Mr. C. O. Waterhouse on Tenebrio ferrugineus.

XXXII.—Note on Tenebrio ferrugineus, Fabr., in the

Banksian Collection of Coleoptera. By CHARLES O.

WATERHOUSE.

J HAVE had occasion to examine the type specimen of Tenebrio

Jerrugineus, F. (Sp. Ins. i. p. 324), and think the following

notes may be useful.

The following is the Fabrician description :—‘ Corpus

preecedenti [Antherophagus pallens] adhuc minus, magis

depressum ferrugineum. LKlytra striata, testacea. Habitat

in Africa equinoctialt.”

The general appearance is something between Pediacus and

Lemophleus; the antenne, however, resemble those of

Gnathocerus, but with longer terminal joint. I cannot call to

mind any insect with a similar thorax. This is flat, slightly

dull, except the smooth median line and fine smooth line

inside the lateral finely reflexed margin; it is only slightly

narrowed towards the base, and the almost rectilinear sides

are peculiar. I can only distinguish four joints to all the

tars1.

I think the species must be placed in the Cucujide, near

Xenoscelis, Woll., which it resembles in many respects, but

has quite different antenne.

The following additional characters will help to identify

the species. Of course the insect so long known in our

collections as Tribolium “ ferrugineum, Fab.,” will have to

bear a different specific name.

Prosternum without process, flat between the coxe, im-

pressed behind them. Mesosternum lightly impressed, with

a slight oblique swelling next the intermediate coxe, which

are moderately separated ; the line dividing the mesosternum

from metasternum curved. Metasternum with a deep longi-

tudinal median impression behind. [Abdomen wanting.]

Apical joint of the maxillary palpi elongate-ovate, very

obliquely truncate at the apex.

Anterior tarsus four-jointed, four fifths the length of the

tibia. The basal joint about one third of the tarsus; the

second and third joints shorter, subequal, slightly produced

beneath ; claw-joint a very little longer than the basal joint.

Posterior tarsus with four joints, the basal one long; the

second with its basal part about one third the length of the

basal joint, produced below into a long rather broad lamina,

extending beneath to about the middle of the claw-joint; the

third joint about as long as the second ; the claw-joint about

as long as the basal joint. The eyes are rather large and very

coarsely faceted. ‘lhe antenne are as long as the head and

thorax together, slightly flattened. The basal joint a little

longer than broad ; second joint very short ; third joint about

one third longer than broad, narrowed towards its base; the

fourth to tenth joints subequal, shorter than the third, very

slightly increasing in width ; the terminal joint as long as the

two preceding joints taken together, elongate-ovate, rather

narrowed towards the apex. Head somewhat as in Pediacus,

but flatter, less narrowed in front, narrowed behind the eyes,

but with a distinct portion behind the eye; surface rather

strongly and rather closely punctured. ‘Thorax broader than

the head, about as long as broad, rather flat, irregularly and

rather strongly punctured (with a fine smooth median line),

broadest just before the front angles, gradually but not very

much narrowed to the base; the sides almost rectilinear,

finely margined; the posterior angles slightly projecting and

acute; the base with two widely separated sharply marked

fovee. HElytra somewhat as in Pediacus, each with the

suture and three fine coste slightly raised ; the intervals flat

and appearing smooth, but there are a few fine obscure

punctures.

XXXITI.—Note on the Synonymy of Huphina lanassa, a

common Australian Butterfly of the Subfamily Pierine. By

ArtTHuR G. Butier, Ph.D. &c.

So much confusion has arisen in the synonymy of this species

that, after carefully working it out, I feel no time should be

lost in putting it straight.

The species was described by M. Boisduval in his ‘ Species

Général’ (1836), evidently from an old female example from

New Holland in which the under surface of the secondaries

had darkened to ochreous with age, and in which there chanced

to be no submarginal spots (we have a specimen in which

the secondaries show only one spot on the under surface).

M. Boisduval considered his specimen to be a male; but he

so often blundered in sexing his species, that no reliance can be

placed upon the statement ‘‘ Nous n’avons pas vu la femelle.”

The description “ la bordure des supérieures assez large ”’ can

hardly apply to a male, unless it be assumed that his method

of description was loose, because an equally broad border to

232 On the Synonymy of Huphina lanassa.

that of males of this species is (in other descriptions) regarded

by M. Boisduval as “ de largeur moyenne.”

In 1852 M. Lucas described a species, also from New

Holland, under the name of Pieris nabis, the male of which

was of the variety having only two subapical spots on the

border of the primaries, the female only differing from typical

“ Pieris lanassa,” Boisd., in having several yellow spots on

the border of the secondaries below.

In 1865 Felder described the female again, but from Fiji,

under the name of “Pierts perithea,’ aud compared it with

the P. perimale of Donovan.

At the same time and on the same page he described a

male from Australia, characterized by having the apical area

of the primaries and the entire basal area of the secondaries on

the under surface whity brown, under the name of P. periclea.

Lastly, in 1867 Wallace described a male from Moreton

Bay in which the apical area of the primaries and entire basal

area of the secondaries on the under surface were “ earthy

brown with an orange tinge.”

Wallace compared his new species with the Prerts nabis of

Lucas and Papilio perimale of Donovan, but he failed to

recognize the latter owing to the fact that the type was

evidently a female. The male of Donovan’s species is, I have

no doubt, the species in Hewitson’s collection which Wallace

incorrectly identified as Felder’s P. periclea. ‘There are two

examples from New Caledonia, differing from each other

exactly as P. narses and P. nabis differ; but, curiously

enough, Wallace does not consider them distinct, as he

logically should do, but observes :—‘‘ These two specimens

indicate a variable species.”

It is absolutely certain that Felder’s “P. pertclea ” cannot

be the species from New Caledonia, which in form of wing

corresponds with its presumed female “P. perimale,” tor

Felder states that it agrees with his P. pertthea:— “die

vorbeschriebene Art, mit welcher die Fligelform iiberein-

stimmt.”

In 1869 Herrich-Schiffer described and figured a Huphina

as P. pertclea, and, later, he reproduced the plate coloured as

part of an Appendix to his ‘ Aussereuropiische Schmetter-

linge.’ The coloured figure is at once seen to be identical

with Wallace’s P. narses, the colouring below not being

whity brown, but earthy brown.

When a large series of Huphina lanassa is examined, it

becomes evident that the species is tetramorphic ; the under

surface cf the secondaries and apex of primaries may be

white, yellow, wbity brown, or earthy brown, but the upper

surface only varies in the number of white spots on the black

border. }'rom what we now know of the seasonal dimorphism

of white butterflies, it is almost certain that the earthy-brown

and whity-brown types are dry-season forms and the yellow

and white types are wet-season forms.

In like manner the two males of P. perimale, which

Wallace regarded as an aberrantly variable species, represent

the ordinary dry- and wet-season forms, of the first of which

Donovan’s type is typical. P. perimale, however, is more

nearly allied to my Huphina terranea, of which we now

possess beth types from Lifu, than to Huphina lanassa.

The synonymy of ZH. lanassa corrected to date will be as

follows :—

Australia, Baudin Island.

In the wet-season form there are all gradations between

the extremes of yellow and white, whilst P. periclea is a

transitional form between the latter and P. narses ; therefore,

if the facts proved as regards the seasonal changes in colouring

in other genera of Pierine should be found not to be true of

Huphina, the above forms would still have to be regarded as

variations of one species.

XXXiV.—On the Species of the South-African Scorpion

Opisthophthalmus contained in the Collection of the

British Museum. By R. I. Pocock.

THANKS to Prof. Kraepelin’s recent examination and com-

234 Mr. R. I. Pocock on the Species of

determination of their age, sex, and specific identity *, I have

found it possible, with some degree, [ hope, of exactness, to

identify the rich material of this genus contained in the

collection of the British Museum. I have added some notes

respecting the various species, which, I trust, may be of

service in their determination; but especially do I wish to

draw attention to the fact that many of the specimens have

been obtained of late years, and are consequently furnished

with trustworthy and exact localities—an item of information

which has been so much ignored in connexion with these

animals, but which will ultimately prove, I think, to be of

the first importance. For instance, when discussing QO, ca-

pensis, apparently the commonest species of all in most

collections, Kraepelin says that its distribution seems to be

exclusively Cape Colony (Capland). This, no doubt, is

perfectly true; but I cannot lay my hands upon a particle of

evidence that the species ranges throughout Cape Colony. It

appears, in fact, so far as I can determine at present, to be

restricted to a relatively narrow but undetermined area around

Cape Town and the Cape of Good Hope; and there is no

evidence known to me that any other species inhabits the

same spot. That many more species than at present are

known from specimens ticketed vaguely “ S. Africa or Cape

Colony ” will be found also to have a restricted range is, I

think, probable, though, on the other hand, there are some—

O. carinatus, for example—that cover a wide area in distri-

bution.

Opisthophthalmus capensis (Herbst).

Scorpio capensis, Herbst, Naturg. d. Scorpione, p, 62, pl. v. fig. 2

Opisthophthalmus maaillosus, id, ibid. (young, teste Kraep.).

Of this species the British Museum has twenty-three

examples of all ages and both sexes. It is evident that Cape

Town is the head-quarters of this species. How far it extends

to the north and east of this point 1 have no means of judging.

Of the above-mentioned examples no fewer than fourteen are

ticketed Cape Town, received from KR. Trimen, R. C.

Wroughton, Rev. G. H. R. Fiske, and H. A. Spencer;

while all the rest that are labelled came from the Cape of

Good Hope. I cannot understand Kraepelin’s reasons for

separating this species from what he calls pilosus, for the

characters he assigns to the latter are merely those of the male

of capensis, in which usually all the abdominal sterna with the

exception sometimes of the first are granular, while the palpi

are very richly hairy; yet Kraepelin speaks of the two sexes,

both of pélosus and capensis, as if he were familiar with them.

I cannot, however, avoid the conclusion that he has in some

way confused the sexual characters; and this opinion is

strengthened by the fact that he considers the figure of the

type published by Herbst to represent a male. It appears,

however, to me to be without doubt a female, as both ‘lhorell

and Simon have affirmed. The male of capensis has a slender

hand, and the first and second caudal seements taken together

are equal to the length of the carapace ; while Herbst’s figure,

with its broad hands and short tail, agrees exactly with all

the adult females in this collection.

A single female from the Concordia Copper Mine, Ookiep,

about 70 miles from the coast in Little Namaqualand, to the

south of the Orange River (collected by W. Hi. Clark), gives

the following measurements in millimetres:—Total length 115;

length of carapace 16°5, of tail 59, of hand-back 10:5, of

movable digit 17°5 ; width of hand 13°7.

The accompanying figure of this species (p. 256) is taken

from a photograph by Dr. Howard of a female specimen

procured near the copper mines, Namaqualand, and sent to

Mr. Lydekker, by whose kind permission I here reproduce

it. ‘The interocular area of the carapace and the hand, which

are blackish in the photograph, are reddish yellow in the

actual specimen.

Two male examples, Otjimbinque (Keyserling collection)

and Umfuli River, Mashunaland (G. A. A. Marshal’). The

one from Otjimbinque presents the discoloration and softness

of exoskeleton characteristic of recently moulted Arthropods ;

the one from. Umfuli, on the contrary, is full-coloured, the

extremity of the tail, the legs, and hands being pale yellow,

while the upper surface of the trunk is greenish brown, the

rare in this genus, namely, although there is a strong con-

trast in colour between the legs (and hands) and the trunk,

the tint of the interocular area of the carapace resembles that

of the trunk. In almost every other case it is the same pale

colour as the hands and legs.

This specimen gives “the following measurements in

millimetres :—Total ‘length 98; length of tail 53, of carapace

14:5; distance of eyes from fron border 8°6. There are 23

pectinal teeth on each side, and the sterna of the abdomen

are strongly corrugated with deep transverse grooves, which

are much more strongly marked than in the specimen from

Otjimbinque.

Another interesting point about this species is that in the

subcentral position of its median eyes and the deepness of the

notch in the anterior border of the carapace it approaches the

genus Scorpio—the so-called Black or Rock Scorpion, which

ranges in Africa from Senegambia to the Congo on the west,

and from Abyssinia and Somaliland to Lake Nyasa (Zomba)

on the east, but is replaced in S. Africa by Opisthophthalmus.

On account of these features this species was by Karsch

regarded as a distinct genus, which he named Petrootcus (a

preoccupied name, which was changed by myself into Gco-

petrus). But since the exact position of the eyes is a cha-

racter liable to considerable specific variation, it 1s, perhaps,

better to hold with Kraepelin that car’natus is merely a well-

marked species of Op!sthophthalimus.

metres as follows:—Total length 99; length of carapace

16:5, of eyes from posterior margin 5; length of tail 48°5, of

hand-back 9, of movable digit 16; width of hand 13.

Both specimens possess 15 pectinal teeth on each side, and

the colour, like that of O. austerus, is a reddish brown, paler

on the legs, hands, and anterior region of carapace.

The localities so far known for this species are Tette on the

Zambesi and Caffraria (!) (Wahlberg Ooll.). The British

Museum has examples from 'T'ette (Keyserling Coll.), Lake

Nyasa, ? southern shore (Universities Mission, Capt. Maclear

and Mr, Bellingham), and from Mashunaland (Salisbury,

5000 feet, Umfuli River, 1200 feet: G. A. AK. Marshall),

making a total of ten specimens (males, females, and young).

The pectinal teeth vary in number as follows :—

Specimens from Nyasa: ¢, 10-10, 11-11; ¢, 12-12,

13-13, 15-13.

Specimens from Tette: ? young ¢, 11-11.

Specimens from Salisbury: 2, 10-12, 13-13; ¢ (young),

16.

Specimens from Umfuli: g (adult), 16-18.

According to Kraepelin the pectinal teeth in the males that

he saw were 18-19, while Peters gives 23 for this sex, a

number which is nearly double that of one of the males from

Nyasa.

Another feature which is, according to Kraepelin, charac-

teristic of this species is the distinctness in the temale of the

upper crest on the anterior surface of the humerus; but it is

not distinctly defined in any of the females examined by me

except in the one from ‘Tette. Moreover, it is only in the

young example from Tette and in one from Salisbury that

the interocular area of the carapace is perfectly smooth. In

all the other specimens it is in both sexes distinctly though

finely granular in front; and in one of the females from

Umtuli the first dorsal plate is finely granular at the sides.

I have very little doubt, however, that all the specimens

under discussion are cospecific.

Of this species, the synonymy of which I adopt from

Kraepelin, the Museum has. only four examples in alcohol,

a. e. one adult female from Durban (Capt. Munn), two young

males from Basutoland (2. C Wroughton), and one adult male

from King William’s Town. The pectinal teeth in these

examples are as follows:— 9 from Durban, 13-14; ¢ from

King Wilham’s Town, 17-18; ¢ from Basutoland, 12-12,

13-13—whereas, according to Kraepelin, they are 15-15 in

a male and 10-12 in the females.

240 Mr. R. I. Pocock on the Species of

Although this species is nearly allied to O. glabrifrons, it

may be distinguished, as Kraepelin has pointed out, by its

more coarsely and thickly granular terga, by the ornamenta-

tion of the hand, which is less granular and composed rather

of low anastomosing tubercles, by the constancy of the occur-

rence of either one or two spines external to the series running

along the lower surface of the third and fourth tarsi. In the

male, too, the interocular area of the carapace is finely

granular throughout and the keels on the hand are stronger.

The colour, too, is on the whole darker, and in the specimens

that 1 have seen the maxillary processes of the first and

second pairs of legs, as well as the tip of the sternum, are

black, while these same skeletal pieces in glabrifrons are

uniformly pale.

I believe the three examples that I have described above

are referable to the same species, since they agree sufficiently

well to permit the supposition that their differential characters

are merely due to differences of age and sex.

According to Prof. Kraepelin’s recent revision of the

species of Opisthophthalmus, this new form falls into the same

section as that containing capensis, pilosus, and pictus. From

the latter, which is unknown to me, granifrons certainly

differs in colouring as well as in having the interocular area

of the carapace granular instead of smooth. From capensis

and pilosus, granifrons may be recognized by having the

interocular area more granular, the hands more granular, and

the inner half of the upper surface much more strongly con-

vex, the finger-keel weaker and strongly granular, and the

crest bounding the upperside of the hand-back and the one

on the upperside of the brachium also strongly granular

instead of smooth. Moreover, in the female of capensis the

proximal intermediate lamella of the pectines is not elon-

gated. Some points connected with colour are also notice-

able. In capensis the crests on the chelz, especially those on

the humerus, are much more strongly blackened and the

maxillary processes of the first and second pairs of walking-

legs are wholly fuscous.

O. granifrons also seems to be readily distinguishable from

the two forms characterized by Thorell and Simon respec-

tively as datro and Chaper/, which Prof. Kracpelin assigns to

pilosus. In O. Chaperi, for example, the humerus and

brachium of the chela are black, the interocular area is smooth

and punctured and only sparsely granular, and the hand is

flat aud nearly smooth above.

According to Kraepelin’s table this species, with its

granular sterna and undivided cephalic sulcus, falls into the

same category as glabrifrons, pugnax, and prado. ‘The

granulation of the upper surface of the hand is rather Gnex

than in male specimens of glabrifrons from Mashunaland and

Nyasa, and the finger-keel is much stronger, while the inner

keel is even less well developed. The carapace, too, is

longer in glabrifrons, excelling the first and second caudal

segments in length and also the fifth, as well as being longer

than the upper surface of the hand. Moreover, the ‘first and

second abdominal sterna in glabrifrons are smooth.

the hand and the obsoleteness of the internal keels, in the

smoother interocular area and shorter carapace as compared

with the uppersurface of the hand and with the first and second

and fifth caudal segments, the relative length between these

parts being about the same in pugnaw as in glabrifrons, in

having all the abdominal sterna thickly and uniformly

granular, and the inferior median keels quite obsolete on the

first caudal segment, instead of coarsely granular as in pugnax.

From predo, which is unknown to me, breviceps seems to

differ in much the same way that it does from pugnax, though

ee approaching it more nearly in the granulation of the

hands.

On the Cross-Fertilization of Flowers by Insects. 249

XXXV.—Notes on the Study of the Cross-Fertilization of

Flowers by Insects. By Ipa A. Kevver, Ph.D.*

OnE of the most remarkable discoveries in plant-physiology

was certainly that of the cross-fertilization of plants by the

aid of insect visitors. That this discovery, made toward the

end of the last century, was founded upon actual fact has

been verified by almost every one who has become interested

in this most remarkable phenomenon. Apparent as it is in

many cases, in more instances cross-fertilization by means of

insects is simply a conjecture. There is no more fruitful

source of error perhaps in the experience of all scientific

knowledge than a sudden brilliant discovery, which is founded

upon careful observations in a limited number of cases, and

the wholesale application of its results without the exercise of

sufficient caution. Again and again the organic world has

been shown to be so complex that no one simple formula can

be found to express adequately the exact situation in each of

a great variety of cases. Experience is constantly showing

that each particular case must be carefully studied by itself

before we can with any degree of certainty gain a thorough

understanding of any general phenomenon in plant or animal

life.

In my attempts to obtain an impartial view of the subject

of cross-fertilization, so far as the actual observations made in

this field up to the present day will permit, I was struck with

a number of curious facts in connexion with the development

of our knowledge in this direction. I must, however, apolo-

gize for the rather meagre presentation of the subject. [

have had neither the time nor the opportunity to acquaint

myself thoroughly with its entire literature, and the original

observations which I have made in this line are limited in

number.

Conrad Sprengel, as we all know, discovered ‘‘ The Secret

of Nature Revealed in the Formation and Fertilization of

Flowers.” Over one hundred years have passed since this

was recorded, and yet the plant-world offers in this respect

one puzzle after another. Instead of having exhausted the

study of the subject by this time, it seems to be gaining in

interest.

Naturally enough, it was not the tendency of scientists to

try to disprove what was evidently true from the observations

Philadelphia,’ 1895, pp. 555-561.

Ann. & Mag. N. Hist. Ser. 6. Vol. xvii. 17

250 Dr. Ida A. Keller on the

of Sprengel, but rather to develop more fully our knowledge

of cross-fertilization. I need only refer to the famous work

of Darwin, to that of the well-known German botanists

Hildebrand, H. Miiller, Kerner, and to that of the many

close observers of our own day.

The fact that cross-fertilization is of utmost value to the

individual species has been emphasized by Darwin. In fact

this great discoverer contends repeatedly that pollen applied

to the pistil of the same flower is a positive injury to the

species. It is curious to note how this idea has influenced

the authors of botanical text-books. As one instance in

many I need only refer to Gray’s ‘ Structural Botany.’ To

the rather long chapter devoted to the description of the

adaptation of flowers to insure intercrossing a few paragraphs

are added in which the writer, it seems to me rather unwil-

lingly, admits that there are also special adaptations to insure

close fertilization—in fact, that there are cases which posi-

tively exclude all chances of a cross. Of cleistogamous

flowers Gray says :—‘ Here the intention and the accom-

plishment of self-fertilization are unmistakable. This peculiar

dimorphism consists in the production of very small or incon-

spicuous and closed flowers, necessarily self-feriilized and

fully fertile, in addition to ordinary, conspicuous, and much

less fertile, though perfect flowers” *. He then continues :—

“ It has been said that the ordinary flowers in such plants are

sterile, and perhaps they always are so, except when cross-

fertilized; in most cases they are habitually infertile or

sparingly fertile. Probably they suffice to secure in every

few generations such benefit as a cross may give, while the

principal increase is by cleistogamous self-fertilization, which

thus offsets the incidental disadvantage of the former mode.”

I have quoted the writer verbatim, because the extract shows

so plainly his mental attitude in regard to the significance of

this phenomenon. Here we have a concession in regard to

the extreme fertility of cleistogamous flowers, followed by a

suggestion in regard to the few mostly infertile conspicuous

flowers which accompany the former, and from these and the

statement that no species is altogether cleistogamous, taken

as a premise, the following conclusion is drawn :—“ Thus,

cleistogamy, with all its special advantage, testifies to the

value of intercrossing.”” The same bias, looking favourably

upon cross-fertilization, may be observed in most writers on

the subject. The prevailing impression seems to be that close

fertilization is, as arule, only resorted to when all the chances

for cross-fertilization are at an end.

It appears that the problem permits of a wholly different

solution. Among the few writers who admit this there is,

perhaps, none who speaks with as much decision and who

adduces as many facts to prove his assertions as does Mr. Mee-

han. In his interesting paper entitled “Are Insects any

Material Aid to Plants in Fertilization ?”’ the conclusions are

as follows :—

First, the great bulk of coloured flowering-plants are self-

fertilizers,

Secondly, only to a limited extent do insects aid fertiliza-

tion.

Thirdly, self-fertilizers are every way as healthy and

vigorous, and immensely more productive, than those depen-

dent on insect-aid.

Fourthly, that where plants are so dependent they are the

worse fitted to engage in the struggle for lite, the great under-

lying principle in natural selection.

These views are directly opposed to the impression one

would naturally receive from text-books on botany. It is

evident that it is of the utmost importance to study the

significance, and, if possible, the cause of each of the various

factors with which we have to deal as pointing either towards

cross- or towards close-fertilization. As already suggested,

it is always a critical matter to generalize where thousands of

species are concerned which have developed under a variety

of circumstances.

Let us now consider the chief adaptations which point

towards cross-fertiliz.ition :—

I. Distinct sexes.

II. Specially adapted or conspicuous corolla.

I1I. Peculiar position of stamens and pistils.

1V. Difference in the time of maturity of stamens and

pistils.

I. Distinct sewes—The male and female flowers being

separated, it is a matter of necessity that the pollen of one

flower finds its way to the stigma of another flower. From a

teleological point of view the intention is clearly shown. We

cannot, however, speak with certainty of cross-tertilization

even in all these cases, except in wholly dicecious plants, at

least not in Darwin’s understanding of the term, which is

that “ cross-fertilization always means a cross between

distinct plants raised from seeds.’ We must therefore be

careful not to include too hastily in this category moncecious

252 ‘ Dr. Ida A. Keller on the

plants, where the male and female organs are borne on distinct

flowers but on the same plant.

II. A specially adapted or conspicuous corolla.—It is these

showy, irregular, or peculiarly shaped corollas that insects

may readily be observed to visit. The questions which here

arise are numerous. ‘The first one to present itself is this:

Has the corolla been developed for the purpose of attracting

insects, and is it the proof which nature gives us that cross-

fertilization is a necessity, or that it is at least favourable to

the preservation of the species? ‘This seems to have been

definitely answered in the affirmative. The number of cases

where the insect has actually been seen to transport the pollen

from one plant to another, however, are few compared with

the great number of species whose flowers would come under

this head. In this connexion it must be remembered how

very often the insect is simply a robber. This past summer

I observed, e. g., a very large patch of Gerardia pedicularia,

the flowers almost all being pierced at the base of the corolla

by bees perching on the outside and never touching stamens

or pistil. Now, wherever it is more convenient for the insect

to reach the desired substance without boring a hole, it is

apt to be taken for a benefactor, even if it simply takes from

the flower without rendering any service in return. There is

another suggestion I would offer in regard to insect visitors.

In observing bees travelling to and from flowers of Kalmia

latifolia, I noticed that very frequently pollen is thrown upon

the pistil of the same flower when the stamens are unfastened

by the insect. I am not prepared to assert, however, that

such flowers proved fertile. I simply throw this out as a

suggestion, and it should be taken for what it is worth.

Professor Willis made somewhat similar observations on the

flowers of Phacelia tanacetifolia. He describes the crawling

of insects over the dense cymes, touching stamens and styles

indiscriminately, and probably knocking the pollen on the

stigmas from the surrounding anthers*. Further, he says

in regard to Phacelia campanularia :— Bees alight some-

times on the corolla, touching styles and stamens, crushing

them all up together with the styles, and probably causing

selt- as much as cross-fertilization ’”’ f. This in spite of the

fact that the flower of this plant is to all appearance well

adapted to secure cross-fertilization. I should not be surprised

if, sooner or later, upon close examination it should be found

* “ Contributions to the Natural History of the Flower,’ Journ, Linn.

Soc. Lond., Botany, vol, xxx. p. 55,

+ Ibid. p. 57. .

Cross- Fertilization of Flowers by Insects. 253

that in many cases where this adaptation to insects seems so

perfect the insect visitors aid in securing self-fertilization, as

these observations seem to indicate.

Ill. Peculiar position of stamens and pistils.—In the pre-

ceding paragraph | have already briefly referred to the flowers

of Kalmia latifolia, perhaps the best illustration of such an

arrangement. ‘The wheel-shaped corolla, with the ten

pockets in which the anthers are held, is sufficiently familiar

to require no further description, Stamens and pistil mature

at the same time. ‘The anthers are held in the pockets of

the corolla ; when visited by insects they are set free, and the

pollen is thrown with considerable force from the anther-sacs

through the orifices. As I have remarked before, I have

observed repeatedly that pollen was thrown upon the stigma

of the same flower. Careful observations should decide the

question how far in such cases, where there is such a pecu-

liar arrangement in the position of stamens and pistils in

regard to each other, close-fertilization is possible.

Even should it be impossible in any case that autogamy,

or close-fertilization, is effected, it must be remembered that

whenever a plant bears many or clusters of flowers the chances

of cross-fertilization are reduced. Insects in such cases may

visit many flowers of the same plant; but this is not cross-

fertilization in Darwin’s sense of the term.

1V. Dichogamy, or difference in the time of maturity of

stamens and pistils.— This appears to me the most suggestive

and interesting phase of this intricate problem. From a

teleological point of view, 7. e. if we look for a purpose, we

must agree with Darwin and his followers that this is one of

the most remarkable adaptations favouring cross-fertilization.

Modern science insists, however, that we must use inductive

methods, and it is the tendency of the present day to search

rather for the causes than for an underlying purpose. If, on

the one hand, we affirm that every organ is modified to serve

some particular use, we cannot believe, on the other hand,

that such modifications are directly due to external factors

over which the plant has no control. J am aware that the

principle of natural selection may find its application in the

most subtle cases ; at the same time it requires, in this parti-

cular instance, a considerable strain to make it ae wba

reference to dichogamy, Mr. Meehan says positively that the

difference between the time of maturity of stamen and pistil

is caused by varying degrees of temperature, and that dicho-

gamy has its origin in this circumstance, “ that whatever its

significance, it arises from no effort innate to the plant itself,

but from an outside force that can have but little interest im

254 On the Cross-Fertilization of Flowers by Insccts.

cross-fertilization’”’ *. It is peculiarly characteristic of the

present day to seek for the effect of external conditions and to

experiment with the modifications that can be brought about

by changing these. For example, Prof. Goebel says, in

reference to cleistogamic flowers, ‘‘ We do not yet know the

conditions necessary for the production of cleistogamic flowers,

but it may be assumed even now that this production is

influenced by external factors wherever a plant has the power

to produce such flowers” +. He then cites experiments made

with Impatiens fulva, where cleistogamic flowers are the

result of poor nutrition. Accordingly it appears at least

possible that experiments might give similar results in

reference to dichogamy.

Attention has often been called to the fact that in plants

especially adapted to insure cross-fertilization there exists in

almost every case a possibility of self-fertilization. The above

statements in regard to dichogamy, if of any value, point to

a different conclusion concerning the final or at least possible

autogamy from that which is generally accepted. It is

assumed that the flower is so constructed that there is every

chance of a cross provided the insect appears to do the work.

This failing, the arrangement is such as to allow pollen to

come in contact with the stigma of the same flower. It is

evident that in every case which seems to point towards cross-

fertilization it is always to a great extent a matter of chance

whether the visitor arrives or not, even when the adaptation

seems most perfect. It should be decided if cross-fertilization

or autogamy is the rule with every species which seems con-

structed so as to attract insects, and this work should be done

in as many different localities and at different times of the

year as possible, since there is no doubt there are great

variations possible in the fertilization of flowers in the same

species caused by different conditions of heat, moisture, &e. ~

If autogamy should in any case prove the rule, we must

regard fertilization by aid of an insect as an exception, not to

call it an accident. Dichogamy probably is then in a measure

due to external conditions. If this is true, it is simply the

result of a “lagging behind” in the ripening time of either

stamens or pistils, and the final autogamy is the result of a

subsequent ‘‘catching-up” in this respect. ‘This is, as I

have said before, probably the most interesting side of the

question, and the one which will no doubt prove the most

satisfactory for experimental investigation.

On the Quadrate Bone of a Gigantic Pterodactyl. 255

In conclusion, I desire to make the following sugges-

tions :—

First. It is evident that the study of the phenomenon of

cross-fertilization of flowers by means of insects is still a

profitable field for observation and discovery.

Second. The effect of external conditions in reference to

dichogamy should be the subject of critical experiments.

Third. Teleological explanations should be avoided as

much as possible, here as elsewhere, according to the spirit

of modern investigation.

Finally. The relative number of cases of cross- and close-

neon should be compared, and it should be determined

if cross-fertilization actually takes place in all cases where

this is assumed.

XXXVI.—On the Quadrate Bone of a Gigantic Pterodactyl

discovered by Joseph Mawson, Esq., F.G.S., in the Creta-

ceous of Bahia, Brazil. By A. SmirH Woopwarp

KS, EGS

NEARLY five years ago Mr. Joseph Mawson discovered the

first evidence of Pterodactyls in the rocks of the Southern

Hemisphere, consisting of two sTEETIEN TE quadrate bones

from the Cretaceous of Bahia, Brazil*. Quite recently he

has returned from a further examination of the cliffs and

shore-reefs in the same district, and now he has obtained

another example of the same bone, interesting not only on

account of the locality, but also as belonging probably to the

most gigantic Pterodactyl hitherto recorded.

The new specimen, shown from the posterior and articular

aspects and in transverse section in the accompanying figures,

belongs to the right side of the head. A little more of. its

proximal portion is preserved than in the previous example,

but the pterygoid plate is similarly broken away, the ee

for its articulation alone being indicated. ‘The bone is much

compressed antero-posteriorly, its outer margin being a sharp

edge, and a transverse fracture immediately above the con-

dyles (fig. C) shows that its lower portion is solid. ‘The

upper portion may have been hollow, but there is no pneumatic

foramen such as often occurs on the hinder face of this

element. Both faces are flattened, but the anterior one is

slightly concave from side to side above, and the posterior

one (fig. A) is remarkable for its relatively great width in the

upper part. The facette for the pterygoid lamina extends

downwards almost as far as the inner articular condyle and

is obscured by adherent matrix; but its boundaries are clear,

and articular (B) aspects, and in transverse section (C). Cretaceous,

and the transverse fracture shows that it was coarsely rugose

and ridged as in the previous small specimen from Brazil.

The articular end of the bone (fig. B) exhibits the usual lack

of bilateral symmetry. ‘The condyles are a little abraded,

though apparently not much damaged, and are particularly

remarkable both for their inequality in size and their tumid

form. The inner is very much larger than the outer condyle,

and the valley between the two is sharply angulated.

Compared with the Pterodactylian quadrates already dis-

covered by Mr. Mawson in the same formation and locality,

the new specimen is about three times as large, and differs

in the marked inequality of the articular condyles, as also in

their less oblique disposition. The new fossil, however,

agrees with the others in having these condyles remarkably

tumid and separated by a narrow sharp valley, thus re-

sembling the corresponding bones of the Jurassic * rather

than those of Cretaceous age}. So far as yet known,

indeed, the articular end of the quadrate in Cretaceous Ptero-

saurian genera is almost saddle-shaped, with acute lateral

borders.

Not being able to determine the genus of the Brazilian

Cretaceous Pterodactyl, it is equally impossible to estimate

the size of the skull or the animal itself from a single bone.

There is too much variation in the proportions of the snout

and the relative dimensions of the head among Pterodactyls

to admit of any such induction. ‘To judge by Marsh’s figure

of the skull of Pteranodon, however, the Brazilian form must

have even exceeded in size the gigantic species of this North-

American genus, of which the head sometimes attains a

length of 4 feet.

MISCELLANEOUS.

The imputed Jealousy of European Workers on Australasian Faunas

by Local Writers. By C. Heptey, F.L.S.

Rererrine to the controversy in the last August and October

numbers of this Magazine, touching the synonymy of Khysota

Armiti, I can readily accept the decision of Mr. Smith, since he has

the advantage over me of consulting a figure. While the identity

of a species may be held a trifling matter, his concluding remark

that American and Australian naturalists jealously resent the inter-

ference of European writers with their respective local fauna, touches

ona topicso large and important that I would crave space to discuss

it further.

When such interference takes the shape of the splendid ‘ Chal-

lenger’ monographs it is received most thankfully; but when it

comes to us, as it often does—I am, of course, not now alluding to

Mr. Smith—in papers ignoring Australian or American literature,

without, or with mistaken, reference to geographical, geological,

and other environment necessary to the proper appreciation of the

subject, and presenting data insufficient for the recognition of the

species dealt with, then we may be ungrateful without being jealous.

Even resentment may be provoked by the flippant manner in which

Australian and some American work is received, no matter how

honestly attempted, by the disregard of our scientific literature and

by the shameful ignorance that pervades all classes in matters con-

cerned with Australian geography.

An apt parable is the story of two children dividing a piece of

bread and jam, of whom the elder licked off the sweets and handed

to the younger the dry bread for his share. What credit may

attach to the naming of species is appropriated by some Europeans,

who leave the drier crust of classification, anatomy, distribution, &c.

to be laboriously worked out by others.

To support these charges by particulars, I will wander no further

than the source whence this discussion arose. Some years ago I

prepared an account of the Land-Mollusean Fauna of British New

Guinea, in studying which I encountered several unfigured descrip-

tions by Mr. Smith. A London writer, who has at his command

the ablest men, the wealthiest museums, and most complete libraries

in the world, cannot appreciate the difficulties under which an

American, and still more an Australian, student pursues his work

in a city far from civilization’s centre, poorly equipped with books,

specimens, or apparatus, and alone from fellow-workers. If

Mr. Smith, who can identify almost any known shell by a glance at

an authentic specimen in his official custody, could realize how the

head of one student of his writings has ached in reading and

re-reading one of his brief unfigured diagnoses and in endeavouring

to match it with a specimen in hand, he would never, I believe,

again issue an unfigured description, Chance, however, later threw

in my path authentic examples of Mr. Smith’s unfigured Papuan

species; and, though I consider it unfair for one writer to cast upon

another the burden of completing his work, I published drawings of

each of them.

My satisfaction in reducing this fauna to order was short-lived,

for Mr. Smith then produced a series of papers in which a con-

siderable number of New-Guinea species were named and described

without figures or precise localities. Now I do not regard the

publication of these descriptions as a mere formal rite whose celebra-

tion invests British-Museum specimens with the rank of type; but

I receive them as an intended aid to Australian students in the study

of their local fauna. Yet a perusal of them does not enable me to

project a distinct image of any of the forms dealt with; nor am I

alone in this infirmity, for one of the most striking of these shells

has since been renamed, described, and figured as an unpublished

species by a German author, Dr. Kobelt. Several of the species are

relegated to the genus Heliaw, which, in the sense Mr, Smith em-

ployed it, contains about three thousand species ; he also draws

specific limits narrower than do some other writers. For the pur-

pose of this argument it is granted that, in adopting broad genera

and narrow species, the best course is followed ; but it will then be

obvious that he who contrasts a novelty with thousands instead of

scores of co-generic forms, and he who sees five species where

another distinguishes three, is under the greater necessity of giving

full details than he who adopts the alternative course. Concholo-

gists have especial reasons for figuring every shell described,

inasmuch as that shell is not a complete organism, such as usually

represents a species to an entomologist or an ichthyologist. If a

carcinologist were required to name and describe a new crab from

an empty carapace shorn of its appendages, or a botanist to publish

a new tree from a handful of leaves, each would probably decline

on the ground of insufficient material; and if he yielded, say to the

importunity of a paleontologist who could furnish nothing else, he

would endeavour to make amends for his fragmentary material by

figuring and describing it in the minutest detail.

To conclude: in the army of science there is no room between an

honoured veteran like Mr. Smith and a tyro like myself for that

green-eyed monster to whom he somewhat harshly alludes. The

object of these remarks will have been attained if I can but induce

European writers to read a little more Australian scientific litera-

ture, to study the geography of this continent with a little more

care, and especially to figure every Australasian shell they describe

as new.

Reply.

I do not propose in any way to modify or withdraw the opinion

expressed in the paragraph of my paper complained of by

Mr. Hedley, who has, however, both misunderstood and misrepre-

sented it. I make no general imputation against all Americans, as

he infers, but, from my own experience and from the testimony of

others, I have reason to know that a jealous feeling has been enter-

tained by ‘* some.”’

With regard to the title of Mr. Hedley’s above remarks, I would

observe that I have made no accusation at all against Australian

writers, and my observation, ‘‘it seems almost as if the ‘ green-eyed

monster’ were tripping in the Antipodes,” was a playful reference to

Mr. Hedley alone, and was prompted by the general tone of his

paper, which I thought might have been withheld until he had

again occasion to deal with the fauna of New Guinea. I may add

that if he had been a little less precipitate he would have been

saved the trouble of writing his comments, for figures have since

been published of the species complained of.

LT may also say, in conclusion, that I do not think it would be

edifying to further encroach upon the valuable space of these

‘ Annals’ with a detailed criticism of the rest of Mr. Hedley’s prolix

remarks. A deal might be said with regard to the relative value

of a good description and a bad figure, of the cost of illustration, of

priority of publication, &c., but cut bono ? E, A. Sire.

P.S.—Since penning the above reply specimens of Mr. Hedley’s

Rhysota flyensis (a synonym of which he complained of my creation

in R. Armiti) have been added to the Museum collection. In my

opinion it is merely a variety of his own R. hercules, described at the

same time !—H. A. 8.

XXXVII.—Report on a Collection of Reptiles and Fishes made

by Miss M. H. Kingsley during her Travels on the Ogowe

River and in Old Calabar. By Dr. A. GintueEr, F.R.S.

[Plates XIII.-XV. ]

Miss Mary H. Kineastey, on returning from her first visit

to the West Coast of Africa in 1894, brought with her a small

miscellaneous collection of zoological specimens, sufficiently

large to show the interest she took in the fauna of the countries

visited by her. Last year she started again from England,

with the object of extending her travels in the interior of the

Gaboon country ; and as she intended to follow during a part

of this expedition the course of the Ogowe River, she readily

fell in with my view that an opportunity of collecting the

fishes of this mighty river should not be lost. ‘The means of

preserving and transporting the specimens were naturally

limited, as Miss Kingsley travelled alone with a native crew ;

besides, whilst traversing the region of the rapids, which

extends over some hundred of miles, the upsetting of her

canoe was a matter of frequent occurrence. Nevertheless she

succeeded in bringing home in excellent condition a collection

of eighteen species of Reptiles and about sixty-five species of

Fishes, which will be enumerated or described in this paper,

besides a number of other, especially entomological, specimens.

During a temporary stay at Old Calabar and a visit to the

island ot Corisco some freshwater fishes were added to the

Ann. & Mag. N. Hist. Ser. 6. Vol. xvii. if)

262 Dr. A. Giinther on Reptiles and Fishes

main collection from the Ogowe River. These will be also

embodied in the present paper, whilst the marine species,

being all well known, are omitted. A case containing the

fishes of Lake Aznigo, which Miss Kingsley visited with

the special object of obtaining its fishes, was unfortunately

lost by the upsetting of a boat.

Thirty years ago scarcely anything but the name was

known of the Ogowe River; but between 1860 and 1870

French officials and traders began to trace its course inland,

discovering a long stretch of rapids in its middle course which

render navigation dangerous and, at places, impossible to any

vessel larger than a boat. Among those earlier explorers an

Englishman, the late Mr. R. B. N. Walker, took a_pro-

minent part*, making two expeditions in 1866 and 1873,

and penetrating to Lopé, in the Okanda country. The survey

of the upper parts of the river was completed by Messrs. de

Brazza and Balay.

All that was known before the year 1860 of the reptiles

and fishes of the Gaboon country has been collected by

Aug. Duméril in bis memoir “ Reptiles et Poissons de

l’ Afrique occidentale,” in Arch. Mus. vol. x. I find that in

the list at the end of his memoir he mentions eight freshwater

fishes from Gaboon, all being from the littoral portion of

the country. In 18677 I described the collection made by

Walker on the Ogowe, adding seventeen species to its fauna,

ten of which were new. ‘This list was increased by six others

found by Buchholz and determined by Peters (MB. Berlin.

Akad. 1876, p. 244). Two years later M. Sauvage com-

menced to publish the results of his examination of the

materials that had accumulated in the Paris Museum (Bull.

Soc. Philom. 1878, pp. 90-103), giving a complete account of

the then knowledge of this fish-fauna in his memoir “ Htude

sur la Faune ichthyologique de l’Ogéoué,” in N. Arch. Mus.

iii. 1880. In it he enumerates thirty-seven species, a part of

which, however, he knew only from the papers of his prede-

cessors. This number has been increased by him in a last

supplementary list to forty-six (Bull. Soc. Zool. France, ix.

1884).

In the present paper I have added to the Gaboon fauna from

Miss Kingsley’s collection the following sixteen species :—

Gobius eneofuscus, Gthr.

Eleotris senegalensis, Stdchr.

* Bull. Soc. géogr. Paris, 1879, p. 114.

of the river is misspelt Ogome.

Eutropius libervensis, Hubrecht.

Chrysichthys Biittikoferi, Stdchr. (= Ch. macrops, Sauv.,

nec Gthr.).

Barilius bibie, Joannis.

Alestes longipinnis, Gthr.

Kingsleye, sp. n.

Mormyrus amblystoma, sp. n.

Notopterus nigri, Gthr.

Deducting from M. Sauvage’s list three species which I

consider merely synonyms, and allowing for four others which

I believe to figure in my and M. Sauvage’s lists under different

names, I compute the total number of species known at

present from this river to be fifty-one, a number which

may be expected to be doubled by future investigations.

The fish-fauna of the Nile consists of about ninety species.

The localities which will be mentioned in this report

are the following :—

Warrt, on the Forcados River (mouth of the Niger).

Azuminé Creek, freshwater, running into the Opobo River,

with a swift current, 25 miles from the sea (Niger

delta).

Egwanga, on the Opobo River (Niger delta).

Corisco Island, off the Gaboon Coast.

Lambarene, Ogowe River.

Talagouga, about 180 miles from the mouth of the

owe.

Kondo-Kondo, an island in the Alemba Rapids of the

Ogowe.

REPTILES AND BATRACHIANS.

The Reptiles were collected at Lambarene, and belong to

the following species :—

agreeing with one figured by Peters (MB. Berl.

Akad. 1876, p. 117).

18. Rana crassipes, Ptrs.

Before passing on to the Fishes I offer remarks on a few

of these species.

POROMERA.

Poromera, Boul. Liz. iii. p. 6.

Nostril between two nasals and the suture between rostral

and first labial. Lower eyelid scaly. Collar present. Back

covered with scales larger than those of the tail, and strongly

keeled, the keels forming continuous longitudinal ridges;

sides with much smaller scales; ventral scales rather large,

imbricate, keeled, the keels again forming continuous series.

Fingers and toes slender, with a double series of smooth, very

small scutes beneath. Femoral pores; no inguinal pores.

Tail long, cylindrical.

Poromera Fordit.

Tachydromus Fordii, Hallow. Proc. Ac. Nat. Sci. Philad. 1857, p. 48.

Poromera Fordit, Boul. 1. e.

General aspect of a Tachydromus.

The scutes on the upperside of the head show longitudinal

ridges either along the middle or concentric with their

margins. The anterior nasal meets its fellow in the median

line behind the rostral. Anterior frontal longer than broad ;

an unpaired small scute between the posterior frontals. Ver-

tical bell-shaped, twice as long as broad ; a pair of anterior

occipitals, half the size of the posterior, between which a

central occipital. The posterior occipitals are fringed by

some smaller marginal scutes. Two large supraoculars on

each side. Seven or eight narrow upper labials, of which

the penultimate is the largest. Four chin-shields on one

side, five on the other. Temporal scales small, strongly

keeled.

Ear very open, vertically long. Collar more distinct in

front of the shoulder-joint, and nearly obsolete across the

chest. Dorsal scales in eight, ventral in ten, longitudinal

series. Praeanal region covered by keeled scales, in size and

shape scarcely differing from those preceding them. About

twelve femoral pores. All the caudal scales strongly keeled.

The fore limb pressed backwards does not reach the groin ;

the hind limb carried forwards extends to the ear. Thigh

finely granular behind.

The upper parts are brown, or, after the removal of the

epidermis, green iridescent. Back anteriorly with a black

longitudinal band on each side of the median line, the two

bands coalescent further behind. An indistinct greenish band

along each side of the neck. Lower parts whitish.

I have given a full description of this lizard, as the specimen

found by Miss Kingsley at Lambarene seems to be only the

second known to exist in collections. Its specific identity

with Tachydromus Fordit of Hallowell might be questioned,

as this author has described the specimen in the museum of

the Philadelphia Academy as possessing only six rows of

ventral scales ; also the scutellation of the preanal region is

differently described. However, as there is a great agree-

ment in other respects between the two specimens, and the

locality (Gaboon) as given by Hallowell points likewise to a

specific identity, I adopt the name given by the latter author.

Dipsadoboa assimilis.

Dipsadoboa assimilis, Matschie, SB. Ges. naturf. Fr. Berl. 1893, p. 178

(Togoland) ; Bocage, Jorn. Se. Lish. iv. 18955 pal’.

The specimen obtained at Lambarene agrees better with

D. assimilis than with D. unicolor with regard to the number

and disposition of the labial shields.

266 Dr. A. Giinther on Reptiles and Fishes

Professor Bocage refers his specimens from [Fernando Po

also to D. assimilis, whilst, singularly enough, I have now

some evidence that the type of D. wnicolor came from the

same island, as 1 received some years ago a specimen from

Fernando Po which is identical with D. unicolor, There-

fore, as far as our present experience goes, both D. unicolor

and assimilis (if they are really distinct) would seem to occur

in Fernando Po, while the former does not extend on to the

mainland.

Atheris anisolepis.

Atheris anisolepis, Mocquard, Bull. Soc. Philom. 1887, p. 90.

Atheris leviceps, Boettger, Zool. Anz. x. p. 651; Ber. Senckenb. Ges.

1888, p. 92, tab. ii. fig. 7 (head).

An adult specimen from Lambarene. The specimens from

which Boettger took his description came from Banana (Congo

delta). The principal distinctive characters of this species

are, in my opinion, the number and size of scales and the

two series of suboculars, rather than the degree of carination

of some of the scales on the crown of the head, which depends

on age.

Thanks to the kindness of Professor L. Vaillant and

Dr. Jentink I have been able, by a re-examination of the

typical specimens described by Schlegel and Mocquard, to

form a definite opinion as to the species of Atherts which

deserve recognition. They are the following :—

1. A. squamigera, Hallowell,= A. subocularis, Fisch.,

probably = A. Burtont’, Gthr. With 17 (in A. Bur-

tonit with 19) series of scales; only one row of

minute subocular scales (exceptionally partly con-

fluent with upper labials).

2. A. antsolepis, Mocquard (i887), = A. leviceps,

Boettger (1887), = A. chloroechis, Boettg., part.

With 22-25 series of scales; two rows of minute

suboculars, the lower row sometimes incomplete,

but always indicated by several scales.

3. A. chloroechis, Schleg.,= A. polylepis, Ptrs. With

31-36 series of scales and with a double row of

suboculars.

4. A. ceratophora, Werner.

Rana crassipes, Buchh. & Ptrs.

One young specimen from Glass, Gaboon estuary.

from the Ogowe River and Old Calabar. 267

This specimen, as well as an adult in the British Museum,

has no vomerine teeth, whilst two short groups are present in

the second of the British Museum specimens, which is inter-

mediate in size between the two former.

A Goby which seems to be very common in the freshwaters

of Liberia and the Cameroon River, and is abundant in the

Ogowe River, where numerous examples were obtained by

Miss Kingsley at Kondo-Kondo, is identical with the species

discovered by Peters in the Zambeze, but not, as Dr. Stein-

dachner thinks, with the West-Indian G. banana, which has

considerably smaller scales on the tail. G. @neofuscus, there-

fore, belongs to the freshwater fauna of Tropical Africa,

extending right across the continent.

CTENOPOMA, Ptrs.

From an examination of a much greater number of speci-

mens than were at my disposal some years ago I have come

to the conclusion that the variation in the characters of the

species is of a limited extent, and that a greater number of

species exist than I was formerly inclined to admit. Neither

is the distinction of this genus from Spirobranchus so sharp

as was supposed, the armature of the opercles not being

equally developed in all species, and very young Ctenopomas

apparently lacking it. At present I divide the specimens

before me under the following specific names :—

I. A very distinct space between anal and caudal

fins.

p. 110.

D. gy A. >. L. lat. 82. L. transv. 21/9.

Body almost as oblong as in Ct. multispine, to which this

species is closely allied. The height of the body is two

sevenths, or less than one third, of the total length (without

caudal), the length of the head two sevenths or rather more

than two sevenths. The snout equals the diameter of the

eye, which is one fifth of the length of the head ; interorbital

space nearly flat, much wider than the orbit. Mouth mode-

rately wide, the maxillary not extending beyond the vertical

from the centre of the eye. ‘The entire margin of the sub-

operculum is armed with prominent spines; also part of the

interopercular margin is spiny. The space between anal and

caudal fins is equal to, or even longer than, the diameter of

the eye. Ventral fin not reaching the vent. Pores on the

head rather small, inconspicuous. Coloration uniform.

Of this species there are two specimens in the British

Museum, 140 and 153 millim. long, both from the Gaboon.

One was obtained by the late Mr. R. B. N. Walker, and

therefore most probably came from the Ogowe River. Both

have twenty dorsal spines, which number does not seem to

have been ever observed in Ct. multispine; from the latter

species the present differs besides in a rather smaller mouth and

much stronger subopercular armature. Vomerine and pala-

tine teeth present.

Ctenopoma nanum, sp.n. (Pl. XIII. fig. B.)

D.=5". A. soy. L. lat. 27. L. transv. 23/9.

Body stouter than in Ct. multispine or Ct. gabonense, its

greatest depth being contained 2} in the total length (without

caudal) and nearly equal to the length of the head. The

snout equals the diameter of the eye, which is contained 43 in

the length of the head; interorbital space rather convex, not

wider than the orbit. Mouth rather narrow, the maxillary

not extending to the vertical from the centre of the eye.

270 Dr. A. Giinther on Reptiles and Fishes

Opercular armature weak; there are only a few spinous

teeth above and below the opercular notch, and none at all

on the sub- and interoperculum. The space between anal

and caudal fins is equal to a diameter of the eye. Pores on

the head entirely covered by scales. Five series of scales on

the cheek, the lowermost covering the preopercular margin.

Ventral fins reaching beyond the origin of the anal, the two

outer rays being prolonged into filaments. Body with darker

cross-bands ; an indistinct oblique irregular dark band from

the eye towards the root of the pectoral.

Two specimens from the Gaboon, 67 millim. long, are in

the British Museum; they were collected with specimens of

Ct. Petherict.

This species does not possess palatine teeth, and I am

unable to see any teeth on the vomer, the head of which,

however, is visible and not covered by the mucous membrane.

Of course the possibility of these specimens being the young

of one of the other species has been considered ; but beside

agreeing among themselves and differing from the other

species in the number of spines, the comparative size of the

eye and width of the interorbital space clearly point to their

being either mature or not far removed from maturity.

Ctenopoma Petherict.

Ctenopoma Petherici, Giinth. Ann, & Mag. Nat. Hist. 1864, xiii. p. 211,

and 1867, xx. p. 110 (part.) ; and in Petherick’s Travels, ii. 1869,

p- 208, pl. i. fig. A. 3

The British Museum contains a specimen the exact

habitat of which is not known, but which was bought with

other West-African fishes. Although thisspecimen differs from

typical Ct. Petherici in the fin-formula, whichis D. +§, A. 3%,

] refer it for the present to the Nilotic species.

In young specimens, 60 millim. long, the opercular arma-

ture and the vomerine and palatine teeth are well developed ;

but these specimens have the body still lower than the adult,

viz. one third of the total (without caudal) ; in the adult it is

a little less than two fifths. The ornamental colours are

prettier than in the adult, the diffuse blackish spot on the tail

of the latter being a complete white-edged ocellus in the

young.

body, and especially the young differs much from that of the

Nilotic species.

Dee. Ase, La lat 25, 1. transy. 22/9.

The depth of the body is scarcely less than one half of the

total length (without caudal), the length of the head a little

less than one third. The snout is nearly equal to the diameter

of the eye, which is two ninths of the length of the head ;

interorbital space rather convex, wider than the orbit. Mouth

narrow, the maxillary extending somewhat beyond the front

margin of the orbit. Vomerine teeth; palatine teeth in a very

narrow linear band. A series of short spinous teeth above

and below the opercular notch ; subopercular and part of the

interopereular margin finely and equally serrated. ‘Tail very

short, the anal terminating immediately before, or subcon-

tinuous with, the caudal. Pores on the head entirely covered

by scales. Five or six rows of scales on the cheek, the

scales near the eye being much smaller than the others.

Ventral fins not prolonged, ” reaching the vent. Soft parts of

the vertical fins scaly. Blackish, a diffuse large black spot

on the end of the tail, in front of the root of the caudal.

This diagnosis is taken from an adult specimen 150 millim.

long ; two young ones, 60 millim. long, differ in the following

points :-—

Their body is somewhat less elevated (though much more

than in young Cé. Petherici), its depth being contained 24

times in the total length (without caudal). Interorbital space

as wide as the diameter of the eye, which is one fourth of the

length of the head. Two or three spines above and one

below the opercular notch ; suboperculum partly and indis-

tinctly, interoperculum not serrated. Vomerine teeth deve-

loped, only traces of palatine teeth in front of the bone.

Coloration as in the adult.

Snout produced, with the upper jaw slightly the longer,

longer than the postorbital portion of the head. Mouth of

moderate width, very slightly oblique, the maxillary reaching

but little beyond the vertical from the nostril. ‘Teeth small,

subequal, with brown pointed tips. The eye is a little less

than one half of the length of the snout and contained 42

times in that of the head; its diameter does not equal the

width of the interorbital space in the largest specimen. Pra-

orbital as wide as the eye. Preoperculum with a broad

scaleless inferior limb, but its width is much narrower than

the cheek, on which the scales are arranged in four series.

The dorsal fin commences above the root of the pectoral fin ;

its spines are of moderate strength, the middle ones being

much longer than the eye. Caudal fin slightly emarginate.

Specimens from Azuminé Creek have sixteen dorsal spines

and the pectoral fin reaches nearly the vent. ‘l'wo faint

broad longitudinal bands on the upper half of the body are

crossed by five or six transverse bands, equally faint, the

parts crossed being of a darker tint. These markings are

more distinct in young examples than in the adult. An

opercular spot.

Specimens from Kondo-Kondo have fifteen dorsal spines

and a rather shorter pectoral. None of the markings are

present beside the opercular spot.

This is a species clearly distinct from Ch. macrops, having

the adipose fin much shorter and further distant from the

dorsal fin. In this respect it agrees with Ch. nigrodigitatus,

which, as a rule, has a more contracted snout and narrower

mouth. However, I have examined large specimens which

it is difficult to refer to either of these two species with cer-

tainty. And the difficulty is increased, as I find that there

are specimens with eleven and with thirteen anal rays in

both the narrow-snouted form (Ch. nigrodigitatus) and the

from the Ogowe River and Old Calabar. 277

Width of the interorbital space equal to the diameter of the

to below the middle of the eye, its extremity being hidden

below the suborbital, when the mouth is shut. Preorbital

about half the area of the orbit; the first suborbital is

narrow, much narrower than the second and third, which

nearly entirely cover the cheek, leaving only a space un-

covered about equal to the size of the first suborbital. The

origin of the dorsal fin is rather nearer to the caudal than to

the occiput; origin of the anal fin below the middle of the

dorsal. Caudal fin deeply forked. Pectoral fin shorter than

the head, not reaching the much shorter ventral. Scales

thin, with very distinct radiating strie ; lateral line sweeping

Ogowe River.

This is one of the most interesting fishes in the collection.

Originally described and figured in a very rude manner from

a small specimen from the Nile, Z. bibie has remained undis-

covered in that river up to the present time. De Joannis

does not mention the bluish cross-bars, which, however, are

very faint. It is most desirable that specimens from the

Nile should be directly compared with West-African ones.

I am unable to arrive at a definite conclusion as to whether

Barilius senegalensis, Steindachner (SB. Wien. Akad. 1870,

Ixi. p. 564, Taf. v. fig. 2), from the Senegal, should be referred

to this species. Lat. 1. 59-63; maxillary extending to

behind the centre of the eye.

T am equally uncertain with regard to Opsaridium Buch-

holzt, Peters (MB. Berl. Akad. 1876, p. 251, fig. 4). It also

comes from the Ogowe River; but, to judge from the dia-

gnosis and figure, Peters’s fish has fewer scales in the lateral

line (46), a smaller eye and longer snout (the specimens are

of about the same size), and a longer maxillary, which reaches

behind the middle of the eye. Peters represents his fish

without any colour-markings.

Assuming that there are two distinct species of Bardlius

in West Africa, from a geographical point of view B. senegal-

ensis would probably prove to be identical with the Nile fish,

whilst the Ogowe specimens described by Peters and myself

might prove to be the second species; but this assumption is

not confirmed by the, description of the various authors.

Thus, as not one of the descriptions extant fully agrees with

our specimen, I apply at present the oldest name to it.

The height of the body is one third of the total length

two sevenths of the length of the head, equal to that of the

Origin of the dorsal fin a little behind that of the ventrals.

None of the fin-rays elongate. A deep black band commences

abruptly in the middle of the tail, opposite to the origin of

the anal fin, and runs to the end of the central caudal rays ;

it is broader at its commencement than at its end. A more

or less distinct dark spot above the commencement of the

I described this species from two young specimens 3 inches

long. Miss Kingsley has rediscovered it at Talagouga, and

collected specimens apparently adult and up to 190 millim. in

length. Thus I am enabled to amend my original diagnosis

in several points.

D. 20-24. <A. 25-29. L. lat. 42-44.

Snout obtuse, with the mouth terminal and, with age, with

the lower lip thickened into a short adipose protuberance.

The upper profile is somewhat more curved than the lower.

Eye small, shorter than (in adult specimens only half as long

as) the snout, situated in the anterior half of the head.

Teeth of moderate size, notched, few in number. The height

of the body is two sevenths of the total length (without

caudal), the length of the head two ninths. The caudal

peduncle is slender, about as long as the head, its depth being

one third of its length. Origin of the dorsal fin a little

behind that of the anal, midway between the root of the

caudal and the head. Pectoral a little shorter than the head,

extending to the middle of the ventral, which is only half as

long and terminates a long way from the vent. ‘The scales

on the anterior part of the trunk are of moderate size; they

gradually increase in size towards behind, and are largest on

the hinder part of the tail and on the caudal peduncle, on the

side of which they stand in three series. Brownish or

silvery, darker on the head. Two black vertical bands

descend from the anterior and hindmost dorsal rays to the

anal, spreading more or less over that fin.

There are some slight discrepancies between this and

Sauvage’s descriptions, which are quite within the limits of

individual variation. Besides, our specimens from ‘I'ala-

gouga belong to the same district as Sauvage’s, which came

from Doumé (Ogowe). Steindachner’s description is more

precise and his figure more accurate; he compared the

species with M/. Sauvagii (Blgr.), which, however, has a

much wider mouth. ‘The specimens described by Stein-

dachner came from Liberia. ‘Thanks to Dr. Jentink’s kind-

ness I have been able to compare the latter with those

Snout short, obtuse, but rather longer than the eye, with

the mouth at its lower side. Mouth narrow, a little wider

than the eye, armed above and below with six notched teeth ;

its corner lies a little in advance of the vertical from the front

margin of the orbit. The upper profile of the head is some-

what more convex than the lower and ascends slightly towards

the origin of the dorsal. Eye one fifth of the length of the

head. The height of the body is contained 32 times in the

total length (without caudal), the length of the head 54 times.

Caudal peduncle extremely slender, longer than the head

(measured from the last anal ray), its depth being only two

ninths of its length. The origin of the dorsal fin is behind

that of the anal and midway between the root of the caudal

and the end of the opercle. The anal extends also further

backwards than the dorsal. Pectoral fin as long as the head,

reaching beyond the middle of the ventral; ventral fin half as

long as the pectoral or as the distance of its root from the

vent. Abdomen behind the ventral fin compressed into a

ridge. Scales of moderate size; there are nine in an oblique

series running from the vent to the lateral line and three and

two half longitudinal series cover the side of the caudal

peduncle. Silvery, light brownish above.

XXXVIII.—Descriptions of some East- African Lycenide.

By Hamitton H. Druce, F.Z.8., F.E.S.

CoLONEL SWINHOE has lately received a collection of Lepi-

doptera from Dar-es-Salaam, and has placed the Lycenide in

my hands for examination. Amongst them are specimens of

Chrysorychia amanga, Westw., and also of C. punicea, Grose

Smith, with which the recently described C. cruenta, 'Trimen

(P. Z. 8. 1894, p. 55, pl. vi. fig. 13, @), is identical. This

figure is a very bad one, and the conspicuous white marking

which is really on the fore wing below the first median nervule

is here shown on the costal margin of the hind wing.

There is also a male Hypolycena Buxtont, Hew., which is

much larger and deeper in colour on the upperside than the

typical form.

Col. Swinhoe has kindly presented us with the types.

the cell and not reaching beyond the first median nervule ;

the inner margin is not white-edged, and in the hind wing

the shining patch is darker in colour and rather less exten-

sive. Underside differs from that of H. casis by the fore

wing having a distinct black line closing the end of the cell,

and beyond this two distinct transverse black lines—the first,

which corresponds with that in Z#. zas¢s, thin and dark; the

second, which is placed halfway between this line and the

outer margin, paler and broader,

larger and the black lines more distinct. ‘Thorax and abdomen

The tuft of hair on inner margin of fore wings below, which

in E. iasis and daspis, mihi, is black, is in H. mermis white,

and the hind wing is of a different shape, not being so pro-

duced at the anal angle, and consequently lesstriangular. It

is also much like Jolaus silanus, Grose Smith, from Mombasa,

the type of which Mr. Grose Smith has kindly shown me, on

the underside, but on the upperside it is distinguished at once

by its much paler blue, by the less extensive colour on the

fore wing, and by the entire absence of the black spots at the

anal angle of the hind wing. I think it probable that on a

close examination J. s¢lanus will be found to belong to the

genus Hpamera.

Part VI. The Fascigeride, Theonoide, Dactylethrata, and

Trepostomata. By J. W. Grecory, D.Sc., F.G.S.

[Concluded from p. 201.]

Family Fascigeride, d’Orbigny.

Diagnosis. —Cyclostomata Tubulata in which the zocecia

are simple open tubes. These arise from a small cupuliform

or discoid base (the Pelagia or Defrancia stage). The zocecia

are monomorphic and greatly elongate. ‘The zoarium con-

sists of tufts, and the apertures all occur at the ends of the

tufts.

Genus 1. Fascrcutrpora, d’Orbigny, 1846.

Fasciculipora, VOrbigny, Voyage dans l’Amérique méridionale, t. v.

pt. 4, Zooph., plates 1839, text 1846, p. 20.

Diagnosis.—F ascigeride in which the zoarium consists of

long tubular zocecia grouped into bundles which branch

irregularly ; these form a loose, open, tufted zoarium, for the

bundles are not connected by platforms nor do they anasto-

mose. The apertures are at the ends of the branches, and

never on the sides, and occur in isolated groups.

Type species: £. ramosa, d’Orbigny, 1839 and 1846.

1. Fasciculipora Waltoni, Haime.

Fascieulipora Waltoni, Haime, 1854, Bry. Jur., Mém. Soe. géol. France,

sér. 2, t. v. p. 200, pl. x. fig. 4.

Diagnosis.—The branches of the zoarium each contain

about thirty zocecia; the branches are marked externally by

longitudinal ridges ; the branching is irregular.

Distribution.—Great Oolite, Hampton, near Bath.

Genus 2. APSENDESIA, Lamouroux, 1821 *.

Diagnosis.—F ascigeride in which the zoarium rises from

a cup-shaped disk. The bundles of zocecia in the adult are

long and are grouped in long irregularly sinuous series.

There are no platforms. The zocecia all open upon the

Discotubigera elypeata, Vine, 1888, op. cit. p. 19.

Diagnosis.—Zoarium small, dense, and hemispherical ; it

grows from a low funnel-shaped central disk; from this arise

the radiating bundles which unite into irregular twisted

lamin. ‘The apertures occur in series or in isolated teeth.

Distribution.—England : Inferior Oolite—Forest Marble.

Foreign: Bajocian, Germany ; Bathonian, France.

Family Theonoide, Busk.

Diagnosis.—Cyclostomata Tubulata in which the zocecia

are simple, short, open tubes; they pass through a Defrancia

stage (Palways). The zocecia are monomorphic.

The apertures occur along raised ridges.

Genus 1. Actinopora, d’Orbigny, 1852.

Diagnosis——Theonoide in which the zoarium is a fat,

simple, adnate disk. The zoarium consists of a central

depression, of a rim crossed by radiating ridges, and usually

also of a flat peripheral selvage.

Type species: A. regularis, d’Orbigny, 1852.

Lichenopora Phillipsi, Haime, 1854, Bry. Jur., Mém. Soc. géol. France,

sér, 2, t. v. p. 206, pl. x. fig. 10.

Diagnosis.—Zoarium regular, circular ; radial ridges about

22 in number, straight, regular, unbranched. The apertures

are biserial. New ridges arise from the interradial valleys.

A broad expansion surrounds the zoarium; this is low and

flat, and is not crossed by the radial ridges.

Actinopora diplopora, Friren, 1893, Bry. ool. inf. Metz, Bull. Soc. hist.

nat. Metz, sér. 2, t. vi. p. 57.

Diagnosis.—Zoarium large and thin; several zoaria often

grow together into a semiconfluent incrustation : the ridges are

from 35 to 50 in number; they are very thin, irregular, and

high, and extend to the margin of the zoarium; they some-

times branch. No peripheral selvage. In some zoaria (var.

alta) the ridges are almost as high as the zoarium is broad,

and the central depressions are accordingly very deep.

Distribution.—England: Inferior Oolite—Great Oolite.

Foreign: Bajocian, Germany.

Genus 2. KOLOLOPHOS, gen. nov.

Constellaria, Haime, 1854 (non Dana, 1848).

Radiopora, pars, Pictet, 1857 (non d’Orbigny, 1852).

Diagnosis.—Theonoide in which the zoarium consists of

flat encrusting sheets formed of numerous radial groups of

zocecia. ‘The radial ridges are broken up into groups, the

arrangement of which is irregularly linear.

Type species: Kololophos Terquemi (Haime).

A ffinities— The type species of this genus was referred

by Haime to Dana’s genus Constellaria, which at that time

was misunderstood. ‘The American fossil has recently been

redescribed by Ulrich * ; it is quite different from this species.

There is a certain superficial resemblance, due to the promi-

nence of radial non-poriferous lines; but in Constellaria

these lines are solid (“ macule ” of Ulrich) and in Kololophos

they are depressions between zocecial ridges.

The nearest ally of this genus is Acténopora; from this it

differs by the confluence of several radial groups into one

sheet and the broken interrupted character of the ridges.

jocian, Germany and France.

Genus 38. THEONOA, Lamouroux, 1821.

Diagnosis.—Theonoide in which the zoarium is massive

and consists either of dense rounded masses of thick incrusta-

tions or erect thick fronds. The surface is crossed by the

broad well-marked ridges; the ridges may expand in some

species into broad tubular elevations.

Type species: 7. clathrata, Lamouroux, 1821.

the surface of the zoarium is broken into ridges, which are

short, broad, and blunt; they never rise into high bilaminate

sheets. Four or five apertures occur together in one width

of a ridge.

Distribution. — England: Great Oolite (jide Morris).

Foreign: Bajocian, France and Germany ; Bathonian,

France.

Theonoa Bowerbanki, Haime, 1854, Bry. Jur., Mém. Soe. géol. France,

sér. 2, t. v. p. 205, pl. x. fig. 3.

Diagnosis.—Zoarium composed of many erect irregular

sheets; the sheets are tall, irregularly sinuous, and branched,

leaving loose funnel-shaped cavities between them. The

zoarium is roughly hemispherical in form.

The radial ridges are long and fairly continuous; the

summits are flat and contain generally 3 or 4 apertures in the

width, but in places they expand and contain 6 or 7 in the

width; the ridges occur on both sides of the sheets.

Distribution.— Inferior Oolite, England.

of the British Jurassic Bryozoa. 291

Diagnosis.—A_ thick incrustation ; the surface is covered

by numerous irregular ridges, the width of which usually

contains two or three apertures. The depressions between

the ridges are deep and usually as wide or a little wider than

the ridges.

Distribution.—England: Inferior Oolite. Foreign: Ba-

thonian, France.

Suborder DACTYLETHRATA.

Diagnosis.—Cyclostomata in which the normal zocecia are

elongate simple tubes of the same general character as those

of the Tubuliporide. Dimorphism occurs, and the zoarium

consists of normal zocecia separated by numerous dactylethre,

which often form the major part of the zoarium.

Zoarium usually large and complex.

Fam. Clausida, d’Orbigny (emended).

Diagnosis. — Cyclostomata Dactylethrata in which the

zoarium is arborescent. ‘T'he zocecia open on all sides of the

zoarium.. The dactylethre are collected into zones or are

scattered regularly or irregularly among the zocecia.

Genus 1. Muuriciausa, d’Orbigny, 1852.

Diagnosis.—Clausidee in which the zoarium consists of

stout branches, cylindrical or pyriform, and in which the

zocecia are distributed throughout the zoarium, and_ not

collected into zones or groups. The apertures occur either

regularly or irregularly.

Type species: J. compressa, d’Orbigny, 1852.

Zoecia long, cylindrical ; apertures distant and irregularly

placed.

Peristomes low. Walls with thin sinuous ridges.

Distribution.—England: Great Oolite—Cornbrash. Fo-

reign: Bajocian, Germany; Bathonian, France and Austria.

2. Multiclausa Jellye, sp. n.

Diagnosis.—Zoarium growing in large dense tufts of thick

irregular branches.

Zoacia cylindrical, long.

Peristomes raised; surface punctate; apertures arranged

irregularly, not very distant and often in irregular lines.

Distribution.—England : Inferior Oolite—Cornbrash. Fo-

reign: Bathonian, France.

A ffinities.—This species is allied to I. Haimez, Greg., but

differs from it by the greater elevation of the peristomes and

by having the zocecia more crowded and the apertures closer

and often in irregular lines.

Genus 2. TEREBELLARIA, Lamouroux, 1821.

Diagnosis.—Clauside in which the zoarium is arborescent

and thick. Zoarial growth is by the addition of Berenicoid

colonies on to the ends of the branches; each colony sends an

expansion downward around the stem (hence growth is acro-

petal and exogenous). The zocecia are reflexed. ‘The aper-

tures occur in zones separated by interzones of dactylethre.

Diagnosis.—Zoarium of erect branches, which are gene-

rally cylindrical and either grow in irregular stumpy branches

(typical form), or expand into thick pyriform masses (form

pyriformis), or into lobed Alcyontum-shaped masses (var.

Jiculina), or regular cylindrical branches (var. ramosa). The

branches dichotomose and may sometimes anastomose (form

reticulata). ‘The surface is level.

Zoecia crowded. Diaphragms numerous. Mesopores

irregular in distribution. Frequently only at the angles

between zoecta, but sometimes completely surrounding them.

Distribution. — England: Inferior Oolite and Great

Oolite. Foreign: Bajocian and Bathonian, France and

Germany ; Callovian, France and Austria.

2. Heteropora laminata, sp. n.

Diagnosis.—Zoarium encrusting, growing in layers super-

posed into thick masses. The surface of the zoarium is

level.

Mesopores irregular in distribution, generally numerous.

Distribution. — Inferior Oolite, Dorset; Bradford Clay,

Wiltshire.

A ffinities.—This species differs from H. conifera mainly by

zoarial characters, though the mesopores are generally more

numerous. ‘The fact that the mesopores are useless as specific

guides is shown by their great variation in different parts of

the same specimen of species of this genus. ‘his shows that

Haime was correct as to the variability in the number of these

structures, though, by his refusal to admit any value to their

complete absence, he underrated their significance.

3. Heteropora oviformis, sp. n.

Diagnosis.—Zoarium small, free, ovate masses.

Zoecia short. Surface of zoarium covered with large

scattered pustules.

Distribution.—Bradford Clay, Bradford, Wiltshire.

XL.—Hermaphroditism among the Apodide.

By H. M. Bernarp, M.A. Cantab., Holes 2a oe

[Plates XI. & XII. ]

In 1890 I published a preliminary notice in the ‘ Jenaische

Zeitschrift’ * announcing that in several specimens of a small

species or variety of Lepidurus from East Spitzbergen the

posterior tip of the genital gland on each side was filled with

sperm-cells, and that that representative of the family was

therefore hermaphrodite.

By the kindness of Canon Norman and Prof. Mébius I was

then enabled to examine representatives of three other species,

viz. Lepidurus glacialis, Lepidurus productus, and Apus

cancriformis. One of each of these was sectioned with the

sole object of ascertaining whether they were also herma-

phrodites. In each case the specimens examined showed in

some part or other the same conversion of epithelial cells of

the genital gland into the minute clear cells which I believed

and still believe to be sperm-cellsf. That representatives of

four different types of Apodide from different parts of the

world should show hermaphrodite conditions would be almost

too marvellous a coincidence, unless hermaphroditism were

under certain circumstances the rule, at least in those members

of the family.

Dr. Benham, in his note on a male of Apus cancriformis in

the February issue of this Magazine, takes me somewhat

severely to task for having let four years go by without

having published any detailed account of these hermaphrodite

specimens. Most people will, however, readily admit that

this delay was justifiable, nay, almost necessary, under the

circumstances ; indeed, I should hesitate before publishing

this paper if I had not become convinced that the herma-

phrodite condition is, after all, not that most commonly found

in these animals.

In the first place, none of the specimens show clearly the

method of formation of the assumed sperm-cells; it was

therefore necessary to obtain better preserved material. It

was some time before, through the kindness of Prof. Bieder-

mann, I obtained well-preserved specimens of Apus cancrt-

formis, Lepidurus productus, and Branchipus stagnalis.

The new material, however, when examined showed none of

the “sperm- forming centres”; had the latter been found, the

results would doubtless have ere now been published. In the

meantime I have been continually hoping that someone, more

fortunate in obtaining material, would publish a full account,

giving the details which were not to be found in my own

slides. I didnot myself feel justified in publishing a detailed

account based upon indifferently preserved material.

I have now, however, waited four years, and not only has

no one rediscovered the hermaphrodite condition of Apus,

but those who have actually looked for it have not succeeded

in finding any traces of it. After all, then, it appears that

my experience must have been a marvellous one. Three

specimens belonging to separate species collected in diffe-

rent regions are examined in rapid succession, in order to

look for a condition already ascertained to be normal in

another member of the same family, and in each case the

same condition is found, and since then it las never been

found again! Under these circumstances I feel that any

further hesitation to make the best of my slides and to give

the results of my observations for what they are worth would

be inadvisable. The bare facts, however lacking in finer

detail, are evidently worth recording. After reading Dr. Ben-

ham’s paper, therefore, I resolved to examine my slides, some

of which had never been looked at again since they were

prepared, and record all that the best microscopic objectives

could show in them.

Before giving these results I may mention two circum-

stances connected with the case which will help further to

justify my delay, if any more justification is needed.

While I found in Germany no hesitation in pronouncing

the minute cells to be sperm-cells, in England there has been

much difference of opinion. This naturally made it all the

more incumbent on me to wait until I had material which

showed the process of formation of the cells in question. In

this I was fwther confirmed when, some three years ago, I

asked my friend Mr. J. E. 8. Moore, at that time working in

the Huxley Research Laboratory of the Royal College of

Science, if he would take over the whole subject and work it

out. I handed him the slides and all my remaining material,

including the Lranchipus. Unfortunately the slides which I

most wished him to vestigate, not showing the finer processes

of cell-division which at that time monopolized his thoughts,

received but scant attention. In his paper “On the Origin of

the Reproductive Elements in Apus and Branchipus” * he

* Quart. Journ. Micr. Sci. vol. xxxv. 1894, p. 277.

298 Mr. H. M. Bernard on

dismissed the question of hermaphroditism with the words

“ certainly the appearances which have come under my notice

favour this view.” The efforts kindly made at the time by

Prof. Howes to obtain specially preserved specimens of Apus

were unsuccessful.

On returning once more to the slides which show the her-

maphrodite condition of the genital glands, I have been

somewhat surprised to find how much en evidence the sperm-

centres are. In each case the first section, passing well

through the genital gland, shows almost immediately what is

wanted. It is quite impossible that they could have been

overlooked had they occurred in any of the specimens in

which they are reported to be absent. They show, however,

certain variations which make it highly probable that in each

species the phenomenon is a normal one under certain life-

conditions, the nature of which we can only surmise.

In what follows, in order to avoid circumlocution, I shall

always speak of the cells which I believe to be sperm-cells

under this name, while admitting that some different interpre-

tation may perhaps have to be put upon them.

The Spitzbergen Variety of Lepidurus glacialis.

In all the specimens examined the epithelium of the poste-

rior portion of the genital tube is modified to a varying extent

in the manner illustrated. Fig. 1 (Pl. XI.) is a longitudinal

section through this portion of the genital gland in a specimen

measuring about 1 centim. long. The genital tube is seen

resting on the ventral longitudinal muscle-strand, separated

from it, however, by the membrane (m) which encircles the

intestinal tube and the genital glands*. The segmental

bulgings of the tube gradually diminish posteriorly, but are

indicated even to the tip. This tip appears in the section as

if separated from the rest, but this is simply because the sec-

tion here passes somewhat tangentially. The drawing repre-

sents the appearance of the section when only a low power is

used. ‘The most anterior swelling shown in the figure occurs

in about the thirteenth trunk-segment, 7. e. two behind the

one which opens externally at the base of the eleventh leg.

The two descending muscles run into the twenty-third and

twenty-fourth appendages.

Figure 2 shows a portion of the same section as seen under

a%millim. apochromatic oil imm. (1°40 n. a.) of Zeiss. The

epithelium appears to have been dissolved into minute, clear,

round or oval cells each with a single chromosome. The

cells are from 4 to 5 w in diameter. In addition to these

cells there is a great quantity of slime. Near the basal

membrane these sperm-cells appear as if embedded in slime

(fig. 2a), while the lumen of the tube is filled up with a fine

reticulum of hardened slime, the meshes of which appear as if

they were round loculi from each of which one of the sperm-

cells has escaped. A few normal epithelial cells are seen

standing up among the sperm-cells; I cannot make out that

any of them are in the act of breaking down. In all cases

the masses of sperm-cells abut directly against apparently

normal epithelial cells.

Lepidurus glacialis.

I have only one series of sections (longitudinal) through a

specimen from Greenland about 23 millim. long. Fig. 3 is

drawn from a section passing through one of the genital tubes.

‘The membrane (m) above mentioned is seen dorsally held up

by the dorso-ventral muscles (dv) and ventrally under the

genital tube. The figure shows the section as seen under

alow power. The genital epithelium up to about the twenty-

fifth appendage (or twentieth leg) is completely disorganized,

but after this point apparently perfectly normal. The lumen

of the tube contains drops of slime, some large and clear

with afew black lumps in the centre, others small, all of them

highly refractive. The transition between the normal and

the disorganized epithelium is again quite sudden, but it is in

this case specially interesting. The disorganization seems to

be undermining the normal epithelium; definite clear-cut

arches run under the epithelial cells, and these arched spaces

are filled with sperm-cells.

Fig. 4 shows the ventral point of transition as seen under

the oil immersion lens. The cells again measure from 4 to 5 be

in diameter. ‘The distal ends of the epithelial cells seem to

be breaking down into slime. The free ends shown in the

figure are not necessarily detached, although appearing so in

the section. ‘The arch running under these epithelial cells is

very clear, as it is also dorsally even with a low power (fig. 3).

There is but one interpretation of this arching, viz. that which

is gathered from observations of the egg-formation. The

cell or cells near the basement membrane, on dividing to form

the four egg-cells, force apart the adjacent club-shaped epi-

thelial cells, which then arch over the developing elements on

all sides. We have in the figures now under discussion clear

300 Mr. H. M. Bernard on

indications of these sperm-cells having originated from a cell

or cells close to the basement membrane, which were arched

over by the adjoining epithelial cells. Further, Moore (loc.

cit. supra) has pointed out that in the egg-formation the eggs

develop very irregularly out of ordinary epithelial cells. It

is obvious that we have the same indifference in the formation

of the sperm-cells, for in the completely disorganized portion

of the tube every single epithelial cell, whether arched over or

not, must have divided into exactly similar sperm-cells. It

looks as if the distal ends of the cells break down into

slime, and the proximal ends divide up into sperm-cells. This,

it seems to me, would necessarily involve the arching over

of those which start the process first.

Lepidurus productus.

I have only one complete series of longitudinal sections of

Lepidurus productus. ‘The section is 23 millim. long; but

as the animal was slightly bent, it probably measured

25 to 26 millim.

Fig. 5 is one of four or five pocket-like outgrowths found

in a section passing well through the genital gland. This

one was selected because it happened to be cut through longi-

tudinally. It is situated quite anteriorly in the body and

dorsally. The rest are scattered about without any apparent

order on the section. There is no marked localization of the

sperm-forming area at the posterior tip of the gland, as in

L. glacialis and its minute Spitzbergen variety. Indeed, in

this animal and in Apus cancriformis the branching of the

tube is so pronounced that it is not easy to ascertain which is

the posterior tip of the gland. Two pockets, however, were

found opening into the axial canal in the region of the

eighteenth appendage, 7. e. very near the duct which dis-

charges the eggs into the egg-pouch.

The figure speaks for itself; there is no special arching of

epithelial cells over the aperture, but in the same section

three low cells or groups of celis (e) close down on the base-

ment membrane are seen arched over by the adjoining cells

and apparently about to develop into eggs or perhaps into

masses of sperm-cells.

Figure 5a is a very small pocket, which looks as if it

might have been produced by the division of one, or at the

most of two, cells over which the adjoining epithelial cells

had arched. The proliferation of the sperm-cells, instead of

forcing up the arched epithelial cells, bulges out the basement

membrane. ‘This figure is given because it again shows that

Hermaphroditism among the Apodide. 301

the production of these minute cells is a parallel phenomenon

with that accompanying the production of the eggs. ‘This, it

seems to me, goes far to justify the assumption that these

cells are the male reproductive elements.

In contrast to this minute pocket, in another section I have

noticed one or two very large irregularly shaped sacs in

which the epithelium was divided up into sperm-cells ; one

occurs, for instance, at the extreme anterior end of the gland

dorsally.

I stated in my letter to ‘ Nature,’ above cited, that these

sperm-cells could be seen lurking in the folds of the genital

duct, apparently for the purpose of fertilizing the eggs in their

downward passage into the egg-pouch. ‘The duct in the

longitudinal sections of the Spitzbergen Lepidurus is con-

tracted and is filled with a solid strand of slime resting on

the round ends of the club-like epithelium, which runs far

down the duct almost to its aperture. In the sections of Lep7-

durus productus the ducts must have been recently stretched.

The following structural details can be made out (PI. XI.

fig. 56). Externally is a thin layer of irregularly branching

or crossing muscle-fibres (mf). Upon these rests the basement

membrane (bm), which is finely wrinkled. Uponthismembrane

small clear nuclei, each with a singlechromosome and exactly

resembling the cells above described, occur irregularly, here

thickly, there very sparsely. Over the whole is an irregular

reticulum of slime with slime-granules. These clear cells are

evidently the cells which I reterred to as the lurking sperm-

cells. Re-examination of them has not shown that they are

not; but beyond their close resemblance to the sperm-cells,

taken in conjunction with the fact that pockets of such cells

occur in the main genital tube quite close to the duct, there

is nothing to show for certain that they are. It is possible

that they may be the nuclei of the cells lining the duct, which,

in its contracted state, are long and club-lke, but in its

stretched state must be flat and extended. They may be

perhaps a trifle larger than the sperm-cells, which range from

4 to 5 pw, these from 5 to 6 w. On the other hand, they occur

very irregularly, often in groups, whereas we should rather

expect the nuclei of the epithelial cells to be uniformly and

rather sparsely spread over the surface.

Most of the unripe eggs in this specimen appear to be

degenerating.

Apus cancriformis.

Of the three series of sections of this species, as above

stated, only one, and that the very first examined five years

302 Mr. H. M. Bernard on

ago, shows the sperm-forming centres. The original speci-

men is just under 3 centim. long, and is peculiar in one point,

which from the first attracted my attention: the alimentary

canal is distended with fine grit. In this very little can be

found which looks lke organic matter from which nourish-

ment could be obtained. The animal had apparently sought

to allay the pangs of hunger by swallowing enormous quan-

tities of fine mud*, This mud shows as a broad black or

brown streak along the section, and the particles of it have

unfortunately escaped in the process of cutting and mounting

and have sypoiled many of the slides. ‘The alimentary canal,

thus heavily weighted with inorganic matter, has changed

its position, It runs along close under the dorsal surface,

having displaced all the branching tubules of the genital

gland which normally arch over it dorsally. The whole

genital gland now lies below the intestinal canal and probably

partially at its sides. This dorsal position of the weighted

alimentary canal is doubtless due to the habit of the animal

of swimming always on its back.

Fig. 6 (Pl. XJ.) shows portions of four. branches of the

genital tube and a ripe egg (e) cut through. One branch con-

tains a ripe egg in its passage along the tube (only partially

shown), while two of them (dé) show portions of the epithelium

dissolved into sperm-cells. One of these is cut transversely

and the other longitudinally. The part drawn is in the

region of the eighteenth to nineteenth appendage, 7. e. not

far from the genital duct. Fig. 7 is a magnification of part

of the longitudinally-cut branch shown in fig. 6, as seen

under the oil immersion objective. The transition between

the normal epithelial cells and the masses of sperm-cells is

quite sudden, and the reduction of the cells has given rise

to the usual slime-globules. ‘The sperm-cells again measure

from 4 to 5y.

Fig. 8 shows a portion of the main or axial tube of the

genital gland some way behind the duct leading to the exte-

rior. A small pocket is seen on the ventral side, bulging

down the basal membrane. In the next section in one direc-

tion this pocket is nearly flattened out. I did not come

across it again in any other section. In the centre of the tube

is a large egg (e) squeezed out lengthways and perhaps cut

tangentially ; the slimy covering of the egg, hardened by the

alcohol, has been broken up by the microtome-razor. In

this case the egg is certainly ripe, and, if the sperm-cells are

* It is worth remarking that the Trilobites had, under certain circum-

stances, the same habit. Strands of argillaceous matter have been found

running through the fossils (Barrande).

Hermaphroditism among the Apodide. 303

ripe, it is difficult to see why the eggs should not be fertilized

by the sperm-cells. The only hindrance would be the coating

of slime. ‘There is no reason to believe that this, which in

the living state would be quite soft, would be sufficient to

prevent one or more sperm-cells from finding their way into

the ege. They may perhaps be mechanically squeezed

through the slimy covering in the process of stretching the

duct on their passage to the egg-pouch.

Fig. 9 shows two tubules lying across one another, in both

of which a portion of the epithelium has broken down into

sperm-cells. One of these alone need engage our attention.

An egg, which has all the appearance of degenerating, occurs

at the tip, while the epithelium of the neck of the tubule

which carries the egg has broken up into sperm-cells and

slime. On one side the proliferation of the cells has caused

the neck to bulge out greatly.

Figure 10 shows the same phenomenon. A couple of eggs

developing at the tip of a tubule dorsally in the region of

the fourth leg or ninth appendage appear to be rapidly degene-

rating. On the other hand, the neck of the stalk-like tubule

is swelling up (from a to ) by the rapid division of the epi-

thelial cells into masses of sperm-cells.

In the foregoing, in order to avoid needless circumlocution,

it has been assumed that these minute cells are sperm-cells.

The question, then, is—Are they or are they not? The

evidence here adduced leaves little doubt that they are.

Until, therefore, it is shown, by direct comparison with the

undoubted sperm-cells of a male, that they do not resemble

such cells in any way, differing entirely in size, shape *, and

mode of origin as far as the last has here been sketched, it

seems to me that we are justified in asserting that the

Apodide are hermaphrodite under certain conditions of exist-

ence.

Before endeavouring to ascertain what the necessary con-

ditions are which lead to this hermaphroditism, one point

raised by Dr. Benham’s paper calls for brief comment. He

speaks of hermaphroditism in Apus as improbable. Nearly

all who have worked comparatively at ovigenesis or spermato-

genesis have emphasized the already admitted fact that both

ova and sperm develop from the same elements, and that the

* Very little can be made out of Kozubowski’s figures and account

(Arch. f. Naturg. xxiii.) of the sperm-cells of a male Apus. It is very

doubtful whether he saw the ultimate sperm-cells, His figures show

what appear to be spherical packets of cells resembling somewhat those

found in the sperm-forming centres of the hermaphrodite specimens.

304 Mr. H. M. Bernard on

causes which result in different ultimate products are mainly

physiological.

Confining our attention entirely to Crustacea, eggs and

sperm have been frequently found developing in the same

gland. Nebeski* found that in Orchestia the sperm develops

in the posterior end of the gland, eggs in the anterior. Ina

Decapod—Gebia major—all the males examined by Ishikawa +

had eggs developing in the posterior end of the gland.

Rudimentary eggs have been found in the testis of a Crayfish,

and the process of the formation of these eggs out of the

same cells, which elsewhere normally form sperm, has been

followed out in detail}. This is also insisted upon by

Moore in the paper above quoted with reference to Branchipus.

Hermaphrodite individuals are said not to be uncommon

among the parthenogenetic Cladocera, appearing about the

same time as the males. To this I shall have to refer

again §. In the face of these records it is difficult to see

why there should be any special improbability in sperm-cells

occasionally appearing along with eggs in the long, branched,

and apparently but little differentiated genital glands of the

Apodidx, a family, be it remembered, in which the males,

in several species at least, are very rare.

My experience, however, shows more than this. The

specimens from high latitudes, containing a rather large

L. glacialis from Greenland and several specimens of the

minute L. spitzbergensis, show one particular portion of the

reproductive gland apparently normally transformed into a

sperm-forming region, while the rest produces eggs. These

arctic dwellers are perhaps arrested rather early in their

development ||. The posterior end of the genital gland

does not grow out into rich branchings, but tapers off

|| As they were caught in large numbers by Prof. Kiikenthal and the

late Dr. Alfred Walter a week or two before the arctic winter set in, it is

impossible to consider the specimens as immature. According to

Dr. A.S. Packard (“ North-American Phyllopod Crustacea,” U.S. Geol.

and Geogr. Surv. 12th Ann. Rep, 1883) 14 millim. was the average size

of his specimens of L. glaccalis, which were nevertheless adults—that is,

if we may judge from the size of their tail-plates.

Tlermaphroditism among the Apodide. 305

gradually with mere periodical swellings. May we not assume

that the failure to form the typical branchings indicates a

lack of nutrition, one result of which is that the cells which

here, under more favourable conditions, might have pro-

duced eggs, divide up into sperm-cells? The evidence,

therefore, certainly points to a normal hermaphroditism

among the arctic Apodide. With regard to the more

central European species, both the hermaphrodite specimens

of L. productus and of Apus cancriformis above described

were apparently suffering some privation in the way of

nourishment, if we may judge from the generally collapsed

condition of the immature eggs; while, further, the con-

dition of the alimentary canal of the specimen of Apus cancrt-

formis clearly indicates a state of semi-starvation.

In these facts, then, it seems that we have some indications

of the conditions which induce hermaphroditism. It appears

that the Apodide which, under favourable circumstances,

produce parthenogenetically, may become hermaphrodites

when food is scarce. This hermaphroditism is thus super-

imposed upon the parthenogenetic females.

On comparing this with observations which have been

made on kindred forms, interesting speculations are suggested

as to the relations of these hermaphrodites to true males.

The males of different families of Cladocera begin to appear

when the year is waning and food is getting scarce. Kurz *

found that the males of Daphnia always appeared whenever

the puddles began to dry up, and he even succeeded in some

cases in producing males artificially by slowly draining off

the water in which the animals lived. This observer, on

accidentally finding hermaphrodite specimens of four distinct

species just about the time when the males begin to appear,

suggested that such were probably of frequent occurrence and

that this might be a sort of provisional arrangement. The

needed males were not immediately forthcoming, and herma-

phroditism tided over the interval.

Kerhervé’s observations led to the same conclusion ; not

only do males appear on the advent of “ hard times,” but the

females undergo a change. ‘‘Quelques jours suffisent pour

transformer une Daphnie parthénogénétique, indifférente aux

males en femelle éphippiale douée d’affection sexuelle, en

pondeuse d’ceufs destinés & étre fécondés. Le facteur prin-

cipal de cette modification, ici je le répéte, est la pénurie des

vivres ” }.

Wien, Ixix. Abth. i. 1874, p. 40.

+ Mém. Soe. Zool. de France, y. p. 227 (1892).

306 Mr. H. M. Bernard on

In this latter case the transformation takes place in the

same individuals, parthenogenetic females becoming sexual

females. Where do the males, which this rapid transforma-

tion in the females implies, come from? Kurz speaks of the

interval of time which must necessarily elapse before any of

the young can develop into males, and during such an interval,

he suggests, hermaphroditism may occur. Are these herma-

phrodites transformed parthenogenetic females, as the herme-

phrodite Apodida appear to be? If so, is it absolutely

necessary to suppose that they stop at hermaphroditism ?

With regard to the Apodide, the records of “ finds”? do

not show that the males begin to appear in the fall of the

year. The rain-pools in which Apus lives are most likely to

dry up and render life difficult in midsummer. Hence males

may occur at any time of the year, whenever, in fact, the

rain-pools threaten to dry up; that is, if the law is the same

for Apus as for Cladocera—that males appear when the

conditions of life are unfavourable.

If this be the case, where do these much-needed males of

Apus come from? Do they develop from eggs specially laid

under the influence of the adverse conditions, or do a certain

number of developing young ones become males instead of

becoming parthenogenetic females, as, under favourable cir-

cumstances, would have been the case? ‘These are questions

which cannot be finally answered for want of data. A few

points, however, are worth considering.

Claus * found that a developing Apus cancriformis at the

twelfth ecdysis showed clear signs of the transformation of

the eleventh leg into the egg-pouch, but that at this stage its

dorsal shield measured only 24 millim.—that is, the animal

was still very small. How long it took to grow to this size

is apparently not stated. Brauer + found that Lepedurus

productus was 7 millim. long after the seventh ecdysis and

sexually mature after the twelfth, which took place thirty-

seven days after hatching. Here are certainly remarkable

differences between the courses of development in these two

forms, but they appear to agree in showing that the process

is a slow one. It appears certain, then, that males could not

be produced from eggs for an emergency. It would take too

long. The eggs laid when the pools were in process of drying

up would certainly take more than a month to hatch out and

develop into sexually mature animals. Indeed, the assumed

unfavourable conditions under which they would be growing

would still further retard their development. It seems more

Hermaphroditism among the Apodide. 307

probable, therefore, that the genital glands of developing

young, instead of producing exclusively eggs, might produce

exclusively sperm, and that the needed males might be more

quickly obtained in this way. As far as I can see, there is

only one difficulty in believing that this takes place. The male

and female glands have, according to Kozubowski, the same

shape, and we know from the hermaphrodite specimens above

described that the epithelium may produce sperm or eggs.

The difficulty, however, lies in the early modification of the

eleventh pair of legs into egg-pouches. 'Thisoccurs apparently

much earlier in Apus cancriformis than in Lepidurus pro-

ductus. If this modification has already set in, when the

direction of development is changed from parthenogenetic

female into male—if, indeed, this change ever takes place—

then we should have to assume that these legs, during subse-

quent ecdyses, revert to the normal type.

There is one feature in my hermaphrodite specimens of

Lepidurus productus and Apus cancriformis which appears to

me of significance in this connexion. ‘The unripe eggs in both

specimens were, as stated, in process of degeneration. Those

which were quite ripe, ¢. e. were filled with well-developed

yolk-granules, beyond being somewhat small, seemed to be

unaffected and to be escaping through the gland towards the

ege-pouch. Nearly all the rest, ¢. e. the unripe eggs, showed

sions of shrinking, as if they were being resorbed, the material

being probably needed for nourishment. In one or two cases

it appears as if there had been a struggle between the yolk-

forming tendency of the egg-cells and “the rest of the animal

organization seeking to resorb the eg gg-protoplasm. The

nuclei were embedded in small compact masses of yolk-disks,

while the rest of the staining protoplasm of the egg-cells was

full of vacuoles and irregular spaces from which the material

had been drawn. It seems obvious that in these two herma-

phrodites an egg-producing stage was coming to an end.

On the other hand, indications are not “wanting that a

sperm-producing stage is in process of development. The

following can be gathered from the figures. The sperm-

masses have been in most cases but very slightly drawn upon ;

fresh pockets completely tilled with sperm-cells appear to be

forming (figs. 5@ and 8); and, lastly, at the tips of certaiu

branches where eggs are “degenerating, the cells just below

such eggs appear to be actively producing sperm-cells (figs. 9

and 10). The appearances therefore all tend to suggest ‘that

a sperm-forming phase was about to succeed an eg eg-producing

phase. It looks, therefore, as if the hermaphrodite speeloene

were parthenogenetic females in process of becoming males!

308 On Hermaphroditism among the Apodide.

I do not assert that this zs the case. Much more evidence,

if possible based upon direct experiment, is needed before such

a transformation could be admittedly established. Appear-

ances, however, point so decidedly that way that I feel

justified in hazarding the suggestion.

I may, perhaps, add that, startling as is even the suggestion

of such a transformation, there is in this particular case

hardly any serious morphological difficulty to be overcome—

so far as I know, none more serious than the reversion of a

single pair of modified limbs to the normal type. In view of

the marvellous transformations which occur in other members

of the Arthropod phylum at times of ecdysis, such a reversion

can hardly be claimed as a difficulty. It seems to me that

the most serious objection lies in the extreme improbability

of an egg-producing gland changing completely into a sperm-

producing gland. If the possibility of such a change is

granted, other difficulties appear trifles incomparison. But it

is just this change which appears to be so clearly indicated by

my slides.

A propos of the fact that these transformations take place in

the parthenogenetic females, it will be remembered that Pel-

seneer, in a valuable paper on “ Hermaphroditism in

Mollusca,”’ endeavoured to show that here also this condition

has been superimposed upon the female *. He suggests the

following stages :—production of spermatozoa in parts of the

ovaries ; reduction in size and number of the males ; complete

replacement of females by hermaphrodites ; final disappear-

ance of the degraded males. Viewing the Apodide in the

same manner, we may suggest the following account of the

reproductive arrangements of the family :— Parthenogenetic

reproduction with suppression of males was brought about by

the superabundance of food in the early summer, 7. e. during

the season of growth and most rapid multiplication. When

the pools dry up and food becomes scarce it is necessary to

produce resting eggs, for which fertilization is necessary.

* Quart. Journ. Micr. Sci. vol. xxxvii, 1895, Pelseneer, following

Brock (Zeitschr. wiss. Zool. xliv. 1886), claims that the same is also true

of the fishes. The recent announcement by Schneider (Mém. Acad. Imp.

Sci. St. Pétersb. (8) t. ii. no. 2) that in Cobitis and Phoxinus the genital

ducts of the opposite sexes are homologous with each other and with the

Millerian duct appears to support this. Pelseneer, however, makes no

mention of the recent papers by Howes (Journ. Linn. Soc., Zool.

vol. xxiii. p. 589) and Stewart (czd. vol. xxiv. pp. 69, 70), nor of others

dealing with the subject, therein cited; this is the more unfortunate, as

Stewart’s description of a hermaphrodite trout with fully developed

genital ducts and “fundamentally a male,” tells directly against Brock’s

hypothesis.

On new Fishes from the Upper Congo. 309

A certain number of parthenogenetic females become herma-

phrodites by the production of sperm in parts of the ovaries.

It is possible that their transformation may continue until

in some cases, the developing eggs being completely resorbed,

the whole gland becomes a testis, and adult males are thus

rapidly produced. At the same time, it is more probable

that the true males are developed, under the influence of the

same unfavourable conditions, out of younger specimens not

yet sexually ripe.

The whole subject of hermaphroditism in the animal

kingdom is one of vast interest and deserves a special study.

The Apodide promise to yield useful results, inasmuch

as they could be experimented upon as Kurz (loc. cit.) experi-

mented with Cladocera. Indeed, the experiments of Kurz

with Cladocera might themselves be profitably repeated,

and individual specimens be carefully examined by the most

recent methods of fixing and staining. Much welcome light

might be thrown in this way upon the whole subject. In the

meantime, in view of the fact that the majority of Apodide

which come into the hands of students are parthenogenetic

females and that the hermaphrodite specimens here described

are as yet unique, Professor Howes has kindly consented to

my depositing the slides in the Huxley Research Laboratory

at the Royal College of Science, South Kensington, where

they can be examined by any one interested in the subject.

XLII.—Notes on some Ethiopian Species of Ischnurine con-

tained in the Collection of the British Museum. By R. I.

Pocock.

Since I published some notes upon the African Ischnurine

contained in the collection of the British Museum ™*, a con-

siderable number of accessions to this group have been made,

and amongst them are some examples, apparently repre-

senting species, which not only are new, but are of additional

interest inasmuch as they bridge over the differences between

the genera Opisthacanthus, Opisthocentrus, and Cheloctonus.

Thus the two species from Madagascar, with their deeply

excised frontal border, large brachial process, and (especially

in madagascariensis) large and prominent lateral eyes, falls

between the South-American Opisthacanthus and the South-

African Opisthocentrus, but may further be recognized from

both by the presence of a well-developed median row of

spicules upon the lower surface of the tarsi. Since, however,

traces of this row are visible in some of the South-African

specimens examined by me, it is, perhaps, not wise at present

to regard it as acharacter of generic value. Nevertheless the

same character is perhaps the only distinctive feature between

the genera Hormurus and Iomachus. So, too, with regard to

Cheloctonus. The examination of the specimen described as

crassimanus shows that two of the characters relied upon,

namely the absence of upper anterior crest on the humerus

and the marginal position of the lateral eyes, can scarcely be

regarded as of more than specific importance. The shape of

the hand, too, though striking enough, is shown by analogy to

be hardly of generic value; so that I am now of opinion that

the three genera under discussion may be looked upon as

identical. Consequently the African genera of Ischnurine +

may be recognized as follows :—

a. Feet thickly clothed below with two rows of

lone stout bristles). tener meat. > |+'s sine Ischnurus, Koch.

b. Feet sparsely clothed below with paired spines

or bristles. *

* Ann. & Mag. Nat. Hist. (6) xii. pp. 316-320 (1893).

+ Collectors in South Africa who are not acquainted with the genera

of Scorpions may readily recognize the Ischnurinz from the Scorpionin

(Scorpio and Opisthophthalmus), to which they are most nearly allied, by

the flatness of the body and claws and the weaker compressed tail. The

group ranges from Gaboon and Mombasa southwards over the whole of

the continent.

Opisthacanthus crassimanus, sp. 0.

Closely allied to O. Jonesti (Poc.), from Murchison Range,

Transvaal, but very much smaller (cf measurements) and

possessing a distinct ridge of granules on the humerus, sepa-

rating its anterior from its upper surface, and also in having

the crests upon the last abdominal sternite and on the lower

surface of the first caudal segment smooth instead of granular.

Measurements in millimetres.—Total length 48 ; length of

carapace 6°5, of tail 22-5, of hand-back 4°8, of movable digit 6 ;

width of hand 6°5.

Loc. East London (H. A. Spencer). A single male ex-

ample.

This example has been selected as the type; but the

Museum has two others of apparently the same species, one

from Caffraria and the other from Natal, from the collection of

the late F. P. Pascoe; also three young examples from

Basutoland (f. C. Wroughton), which are provisionally

referred to this species.

It is possible that these examples will prove to be the

young of C. Jonesiz, but the only sign of immaturity shown

by the type is the absence of lobes on the digits. More-

over, analogy lends no support to the view that the distinctive

features of this form are due to immaturity. The interest

attaching to the species lies in the fact that the presence of

the anterior crest on the humerus bridges over one of the

distinctions between the genus Cheloctonus and Opisthocentrus.

It may be added that the spine-armature of the tarsi in

these two species resembles that of the West-African species

O. africanus, Sim., there being three posterior and two ante-

rior spines, with the distal inferior angle of the tarsus tipped

with a bristle, and not with a spine as in O. validus, Thor.,

and O. asper (Pet.).

314 Mr. R. I. Pocock on

Opisthacanthus rugulosus, sp.

Colour of trunk, tail, and chele a deep blackish green above,

a little paler below; legs deep brown, paler distally ; coxal

areas brown, sometimes mottled, the maxillary processes of

first and second legs deeper tinted; vesicle pale yellowish

brown.

Allied to O. validus, Thorell.

Upper surface of trunk finely and closely granular through-

out ; the median eyes small, the space between them about

equal to or greater than a diameter ; the three lateral eyes

evenly spaced. Sterna smooth, polished, and finely punc-

tured throughout, the last obsoletely crested.

Tail three and a half times the length of the carapace ; the

lower side distinctly carinate, as in validus, the upperside

laterally more coarsely granular than in that species ; vesicle

compressed, granular below.

Chele more thickly and coarsely granular than in validus,

both hand and brachium being closely and distinctly granular

above ; so also are the crests on the upper and lower edges of

the inner surface of the hand more coarsely granular; hand

thicker and more convex above, its width being very nearly

equal to the length of the keel along the hand-back ; the two

digits lobate in the adult. ;

Legs punctured ; femora externally feebly granular; tarst

armed below with 4 inner and 3 outer spines, but there 1s no

spine on the lower angle. ;

Genital operculum in male transversely oval, much wider

than long.

Pectinal teeth 6.

Length 72 millim., of carapace 9:3, of tail 33; width of

hand 7'5; length of keel of hand-back 8, of movable digit 9°3.

Loc. Ishiromo, Nyasaland (Sir H. H. Johnston).

Easily recognizable from O. validus by its coarser granula-

tion, especially of the upper surface of the hand and brachium,

these areas being almost smooth in validus, with the hand

furnished with a reticulated pattern of smooth low ridges. In

validus, too, though the number of spines on the lower tarsi

is the same, there is one upon the inferior angle of this

segment.

The African species of this genus may be recognized by

the following key :—

a. Hand not so flat ; very wide, the width exceeding

the length of the hand-back ; less of the carapace

showing below the lateral eyes; anterior crest

with two crests of strong granules ; flat and depressed, the

two areas of the upper surface meeting at right angles; width

Genus Hapogenss, Kraepelin.

(=Ischnurus of all authors, except C. Koch.)

Hadogenes paucidens, sp. u.

It is needless to describe this species at length, since it

seems to differ from the South-African forms that Kraepelin

has described under the name ¢richiwrus in the spine-armature

of the fifth caudal segment. In ¢richiwrus the inferior keels

of this segment are furnished with a considerable number of

small teeth, there being upwards of 15 or more smallish teeth

on the median keel and upwards of 9 or 10 similar teeth on

the lateral keels; but in pauctdens there are only 5 much

larger teeth on the median keel and 4 or 5 large ones on the

lateral keels. The teeth on the lower surface of the second

caudal segment also larger and fewer.

Number of pectinal teeth 14 or 15.

Measurements in millimetres of type.-—Total length 119, of

tail 56, of carapace 15; width of hand 10; length of hand-

back 16, of movable digit 14.

Loc. West Africa (type Keyserling Coll.).

In addition to the example described above the Museum

has a couple of dried specimens from the Congo (A. Currer,

Esq., R.N.) which appear to belong to this species, since they

present the same armature of the caudal segments. One of

these is very young, measuring only 39 millim., and possesses

19 pectinal teeth ; the other, which appears to be a not quite

adult male 86 millim. in length, has 24 or 25 pectinal teeth.

The following are the distinctive features of the remaining

specimens of this genus contained in the British Museum :—

Firstly, a male 101 millim. long, of which the tail is 60 and

the carapace 10 (pectinal teeth 16 and 17) ; and a female 84

millim. long, of which the carapace is 11 and the tail 44

(pectinal teeth 14). These two examples, which have no

locality, are evidently sexes of the same species, and by the

strong lobation of their digits appear to be adult. There is

Ethiopian Species of \schnurine. 317

little doubt that they are specifically identical with the type of

trichiurus described by Gervais, as is shown by the strong

terminal spine-armature of the superior keels of the second

and third caudal segments. In both the vesicle is smooth

and the carapace distinctly excised in front.

Secondly, a female from T'ette measuring 147 millim., of

which the tail is 68 and the carapace 18 (pectinal teeth 15 or

19) ; a second specimen of the same sex from Umfuli River,

Mashunaland, 1200 feet alt. (G@. A. K. Marshall), which

measures 140 millim., the carapace being 16 and the tail 68

(pectinal teeth 16). These two specimens, which appear

specifically identical, are doubtless referable to the form

recorded by Peters from Tette as troglodytes. According to

Kraepelin this species of Peters is identical with trichiwrus of

Gervais; and the former would recognize only one species of

this genus. According, however, to the material available to

me tor examination, there may be two South-African species

in addition to the new one here described as paucidens ; these

may be recognized as follows :—

a. Keels on the lower surface of the fifth caudal seg-

ment furnished each with about five strong spini-

form teeth; the rest of the characters as cited

By the kind permission of Sir William Flower I have been

allowed to look through the zebras in the collection of the

British Museum, some skins having lately been received which

hardly seemed to me to agree with any of the recognized forms ;

and I now give a preliminary description of two well-marked

local forms of Burchell’s zebra.

Equus Burchelli Granti, subsp. nov.

General pattern of the stripes as in 4. Burchelli Chapmanni,

but having far narrower light spaces between the broader

dark stripes of the haunches, with no intermediate shadow-

stripes. The spots above the nostrils are of much the same

colour, but rather lighter than the stripes of the face and

body, which are brown or chocolate-colour, varying somewhat

in intensity.

mannt, but having the dark stripes upon the haunches of

about the same width, or slightly broader than the intervening

spaces, with no intermediate shadow-stripes whatever. ‘The

face ; maxillary palpi two-jointed, the basal joint nodular,

the second elongate, slightly curved, and tumescent before

the obtusely pointed apex. Prothorax transversely rectan-

gular, scarcely declivous in front, without propleural fovee,

but in the female with a deep incised transverse striga before

the middle of the dorsum. ‘Tibize widened from the base to

the truncate apex, their upper border straight, rather weakly

serrate, their outer face scabrous. ‘Tarsi short, stout, the first

three joints subequal, the third bilobed. Underskeleton and

elytra as in Phleoborus, but with the prosternum more de-

pressed before the coxe, and the antecoxal ridges very strong ;

abdomen relatively shorter.

The genus differs from Phleoborus essentially in the solid

antennal club and two-jointed palpi; the appearance and

sculpture are quite those of a Phiw@oborus. As yet it contains

a single Oriental species. The etymological alteration of the

generic name by Gemminger and Von Harold is too great to

be substituted justifiably for Chapuis’s hybrid compound.

appears to be identical with the typical one, though some

specimens show slight differences in the tuberculation and

punctuation of the elytral apex. However, the curious

disparity in size between the sexes, which appears to be

constant in the Ternate and Celebes examples, is not main-

tained, as the one male and ten females I possess all range

from about 8 to 9°5 millim.

ETHADOPSELAPHUS, gen. nov.*

Dactylipalpo affinis; discedens palpis maxillaribus brevibus, tri-

articulatis.

This genus differs from the preceding in the fact that the

maxillary palpi are short and three-jointed, the two basal

joints being cylindrical, the first transverse, the second rather

longer, the apical joint shorter and conical. The labial palpi

are not quite so elongate as in Dactylipalpus, but are two-

jointed, and the structural characters are in other respects

identical, the characteristic thoracic striga being present in

the females.

Inconvenient as it is to separate a genus on such a point

of structure, it is one too important to be disregarded, and

fortunately, owing to the large size of the species, the

maxillary palpi can, with a little trouble, be examined

without dissection. The two-jointed condition of one or both

pairs separates this and the preceding genus from other

Scoly tine ; and it is noticeable that, though in the three-

jointed maxillary palpus Lthadopselaphus forms a_ link

between Phiwoborus and Dactylipalpus, its two species, both

African, have a peculiar elytral sculpture, and do not

resemble each other or any species of the allied genera.

£. cicatricosus, which I have more thoroughly examined,

may be regarded as the type.

1. Ethadopselaphus cicatricosus, sp. n.

Oblongus, opacus, niger, pilis brevibus, appressis, cinereo-flavis

at the base of the rostrum; the latter narrower in the male,

with the side-margins more elevated and- frontal surface flatter,

pubescence short in both sexes; antennal club acuminate-

oval, compressed. Prothorax nearly twice as broad as long,

rather narrower at the apex than at the base, the sides

gently curved, the anterior angles nearly rectangular, the

base deeply impressed on either side for the reception of the

elytra; surface (¢) gently convex longitudinally, with a

slight transverse impression behind the apex, covered with

moderately close decumbent hairs, and scabrous with close,

elevated, confluent rugze, stronger at the sides, which are sub-

muricate, and absent over a shining central line, more or less

abbreviated behind and widened in front; surface ( 2 ) flatter,

muricate at anterior angles, the transverse striga of variable

length, situate before the middle, margined by a shining

rugosely punctured area. Scutellum very small, shining,

oblong. Llytra strongly rounded at the base, with irregular

sulci, coarsely and rugosely punctured, shallow before the

diately behind with the fourth; the fifth confluent with the

fourth just after the base; outer sulci subangulate inwards

after the base; interstices convex, especially towards the

apex, rugose, granulate at the base, covered with short, rather

coarse, decumbent hairs, and divided by the confluent sulci,

so that the third interval has three, the fifth two, the seventh

one, subcallose enlargements on the disk.

thorax strongly transverse, much wider in front than the

head, its anterior margin concave, the sides gently curved ;

surface covered with small granular asperities, stronger at the

sides and apical angles, the transverse striga conspicuous, its

less ; between the anterior margin and the apical border is a

fringe of upright hairs. Scutellum minute. Hlytra one fourth

longer than broad, very strongly rounded at the base, the

shoulders obliquely rounded; covered with decumbent hairs

arising from small asperate points, irregularly placed and

stronger at the base and sides, the striz completely obsolete

except at the base and extreme apex, where they are very

feebly impressed, and have a just discernible row of minute

punctures.

Hab. Begoro in Ashanti.

I dedicate this species, curious in the obsolescence of the

elytral striz, to M. Grouvelle, from whom I have received it.

The following genus belongs to the Tomicides :—

STYRACOPTERUS, gen. nov.*

Caput globosum, receptum ; oculi ovales, emarginati; antennarum

funiculus brevissimus, 3-articulatus; clava magna, compressa,

latitudine longior, oblique suboyalis, margine inferiore minus,

superiore fortius curvato, suturis tribus notata. Prothorax

transversus, fere semiglobosus. Elytrorum margo basalis elevatus,

crenatus. Coxze anticee subcontiguee. Pedes fere ut in Liparthro

constructi, tarsorum articulis 1, 2 perbrevibus.

Head globose, large, concealed above by the prothorax.

Eyes broad-oval, emarginate. Antenne situated in the

ocular emargination, the scape rather long, slender basally,

strongly clavate at the apex; funiculus very short, three-

jointed, the second joint conical, the third transverse ; club

large, flattened, much longer than broad, its inferior border

nearly straight, the superior rounded, the tip subacuminate

and situate below the middle line; surface shining, with three

fringed sutures, the first transverse, near the base, the second

transverse on the outer face, obliquely curved on the inner

face, the third near the tip, obliquely curved on both faces

and concentric with the apical margin. Prothorax trans-

verse, nearly semiglobose, with no side-margin. KHlytra

raised and crenate at the base, overlapping the prothorax,

strongly spinous in the single species. Anterior coxe sub-

contiguous, separated by a narrow prosternal process ; middle

cox widely separated ; abdomen short, the first four segments

successively decreasing in length. Anterior tibiz slender,

narrowed at the apex, feebly asperate above, and terminating

in a recurved uncus; middle and posterior tibiz flattened,

not wide, the upper border rounded and finely dentate towards

the apex, of which the lower angle is spinous ; tarsi short,

the first two joints very small and difficult to observe, the

third longer, the apical joint as long as all the preceding.

The genus appears to be related to Liparthrum and Hypo-

borus, differing in antennal structure. I have not been able

to dissect the mouth-parts, owing to the small number of

available specimens and their already mutilated condition.

Styracopterus murea, sp. Nn.

Breviter ovatus, opacus, squamis brevibus cinereis quasi crusta

opertus, obscure ferrugineus, capite, prothoracis apice, elytris

ad basin nigricantibus, antennis pedibusque testaceis; pro-

thorace rugoso, medio rarius elevato-granulato ; elytris punctato-

striatis, ad basin interstitii 2* carinula trispinata, cum crista

Long. 1-4-2 mm.

Short-oval, convex, dull, covered thinly with very small

cinereous scales, which give it a dirty appearance. Head

black, front with a transverse impression, crossed by a fine

elevated longitudinal line, pilose above; mouth densely

fringed with fulvous hairs; antenne yellow-testaceous, the

scape fringed with a pencil of very long hairs. Prothorax

much broader than long, narrowed in front, the sides rounded

throughout, the apex somewhat obtuse, the base bisinuate ;

strongly convex above, somewhat gibbous in the middle, and

declivous in front, obscure ferruginous, with the apex blackish,

rugosely punctured, the punctures containing appressed

scales, the sides with a few longer scales ; median portion of

disk with small scattered elevated granules. Scutellum

absent. Elytra about as wide as the thorax and more than a

half longer, their basal margins elevated and serrate, over-

lapping the prothorax, the sides straight to the middle, thence

broadly rounded to the apex; surface obscure ferruginous,

blackish at the base, squamous, punctate-striate, the punctures

large, quadrate, the rows somewhat interrupted and deflected

by the interstitial armature; second interstice elevated at

base and furnished with three strong teeth, the hinder one the

largest, the elevation connected behind by a ridge with one

on the apical half of the third interstice, which carries four

very large erect acute teeth ; fifth interstice (from the base to

the middle) with a crest of seven acute teeth, increasing in

size posteriorly ; seventh with a toothed crest from near the

base to the apex, which helps to form an acutely serrate

margin to the elytra when seen from above.

Underside fusco-piceous, pilose and thinly scaled. Legs

testaceous.

Hab. British Bechuanaland (F. Whitworth Jones).

The extraordinary development of the elytral armature in

this species has no parallel among any described Scolytide,

though it is feebly approached by some species of Phlwosinus.

Of the teeth which compose it by far the largest are those on

the third interstice. I possess three examples, of which one

is much smaller than the other two and has this armature

less developed. The frontal and antennal characters, how-

ever, correspond, and it is likely that all three are males, the

smal] specimen being depauperized.

XLV.—On the Seasonal Changes in the Plumage of Zosterops

cerulescens. By ALFreD J. Norru, F.L.8., Ornitholo-

gist to the Australian Museum *.

In describing Zosterops westernensis of Quoy and Gaimard in

the ‘Catalogue of Birds in the British Museum’, Dr. R.

Bowdler Sharpe makes the following observations :—“ An

Australian specimen has been described, and it is extraordinary

that a bird which seems to be widely distributed on that

continent should so much have escaped notice, the only allu-

sion to the species that I can find in Mr. Gould’s work being

a passage where he mentions that some specimens of Z, ceru-

lescens have the ‘throat wax-yellow.’ It seems to be the

Z. westernensis (Q. & G.), a species re-instated in the system

by Dr. Hartlaub (J. f. O. 1865) p. 20.”

With a view of solving the mystery why so common a

species should have been overlooked by most writers, I have

given this subject my attention for the past two years, by

* From the ‘Records of the Australian Museum,’ vol. ii. no. 7,

pp. 98-100.

Ann. & Mag. N. Hist. Ser. 6. Vol. xvii. 23

326 Mr. A. J. North on the Seasonal Changes

careful observation and the collecting of a number of specimens

of Zosterops found in the neighbourhood of Sydney. For a

liberal supply of these birds every month, from January until

the end of August, the thanks of the Trustees are chiefly due

to Mr. H. J. Acland, of Greendale, and for a small series of

Tasmanian skins to Mr. E. Leete Atkinson, of Table Cape.

Mr. J. A. Thorpe, the taxidermist, too, has assisted at various

times, and from the specimens collected or sent me for exam-

ination has prepared a series of nearly fifty skins in every

stage of plumage. The results of my observations conclu-

sively prove that the Z. westernensis of Quoy and Gaimard,

the type of which was obtained by them at Western Port,

Victoria, is only the spring and summer attire of Z. ceru-

lescens of Latham. ‘Taking the two extreme phases of winter

and summer plumage exhibited in Z. cerulescens, it can be

easily understood why each phase should be thought to belong

to a distinct species ; and it is only where one has these birds

under daily observation and obtains specimens during every

month of the year that the intermediate stage or the gradual

transition of one phase of plumage to the other is observed.

These changes in the plumage of Z. cwrulescens have already

been pointed out by me in a series of skins exhibited in

August last at a meeting of the Linnean Society of New

South Wales. ‘Typical examples of Latham’s Z. cwrulescens*

with the deep tawny-buff flanks and grey throat, the autumn

and winter attire of this species, may be obtained in the

neighbourhood of Sydney from the middle of April until the

end of August. Some specimens, however, are to be found

during April that have not quite lost their summer plumage,

and in August others that have already began to attain their

spring livery; these birds have the yellow throat more or

less clearly defined. Usually the first indications of losing

the deep tawny-buff flanks and acquiring the yellow throat

are seen, during a normal winter, about the second week in

August, in some seasons a fortnight earlier; but in two

specimens examined the grey throat was retained as late as

19th September. During August and September, however,

the gradual transition from the winter to the spring attire

(the Z. westernensis of Quoy and Gaimard) f is slowly taking

place, and by the middle of October not a bird is to be seen

with the deep tawny-buff flanks and the grey throat. Speci-

mens shot in November have the throats of a brighter olive-

yellow than at any other period of the year, the flanks at

that time being of a very pale tawny brown. At midsummer,

* Z, dorsalis (Gould), Birds of Austr. iv. p. 81.

t Voy. de l’Astrolabe, pl. xi. fig. 4.

tn the Plumage of Zosterops cerulescens. 327

when the breeding-season with the species is virtually over,

the throat is shghtly paler than in the spring, and this livery

is retained until the beginning of March. The flanks then

become darker, increasing in intensity of colour from that

time forward, the yellow feathers on the throat also disap-

pearing and passing into grey until the autumn livery is

again tully assumed by the end of April.

Of six specimens obtained at Table Cape, Tasmania,

during April 1894, three have the throat grey, the remainder

faintly washed with yellow, and in all of them the flanks are

of a deeper tawny buff than in Australian examples.

The distinguishing characters in the seasonal changes of

the plumage of the under surface of Z. cwrulescens may be

briefly summarized as follows :—

Spring plumage.—TVhroat bright olive-yellow ; chest and

breast ashy grey, passing into dull white on the abdomen;

Hanks very pale tawny brown; under tail-coverts dull white,

in some specimens washed with yellow.

Summer plumage.—Similar to the spring, but the throat

slightly duller in colour,

Autumn plumage.—Throat faintly washed with olive-

yellow or gradually passing into grey ; flanks tawny buff.

Winter plumage.—Chin and sides of the throat dull olive-

yellow ; centre of the throat, the chest, and breast ashy ;

flanks deep tawny buff; abdomen and under tail-coverts dull

white, the latter in some specimens washed with yellow.

Transition from winter to spring plumage. — Throat

greyish white, faintly washed with olive-yellow; flanks pale

tawny buff; under tail-coverts dull white, slightly tinged

with yellow.

Cbs.—The average measurements of examples obtained

during winter and in summer are alike. All through the

year some specimens are found with the under tail-coverts

tinged or washed with yellow. This does not appear to be a

sexual character, although from the specimens examined the

yellowish wash on the under tail-coverts predominates

among the males. As a rule, however, the dull white or

white under tail-coverts are found in birds obtained during

the winter.

Under the synonymy of Z. westernensis Dr. Sharpe includes

328 Miscellaneous.

Z. tephropleura of Gould, from Lord Howe Island, but the

latter species can be readily distinguished from the spring

plumage of Z. cerulescens by its bright yellow under tail-

coverts and by its larger and more robust bill. At the

Macleay Museum I have examined the type of Z. Ramsay,

described by Mr. George Masters from specimens obtained by

him on one of the Palm Islands lying north of Halifax Bay,

N.E. Queensland. It is a good and distinct species, with

olive-yellow under tail-coverts and a broad zone of white

feathers round the eye. Dr. Sharpe, from the description of

this species given in the ‘ Proceedings of the Linnean Society

of New South Wales’ *, considers it probably identical with

Z. westernensis ; but there is no question that the specific

character pointed out by Mr. Masters and the olive-yellow

under tail-coverts will prevent one when examining this

species from confounding it with the spring or summer

plumage of Z. cerulescens or with any other Australian

member of this genus.

MISCELLANEOUS.

On the Coloration of certain Insects of the Order Lepidoptera.

By Emre Buancwarp.

I nave made numerous experiments with a view to modifying the

colour of certain Lepidoptera; these experiments have been made

more particularly on the butterfly commonly known as the Peacock

(Vanessa io), the most richly coloured of all our Lepidoptera.

Taking young caterpillars on the point of hatching from the egg, I

placed them in boxes under red, green or blue, and violet-coloured

glass. On the day of hatching no colour had undergone the slightest

modification. Individuals reared in complete obscurity were

hatched as brilliantly adorned as those reared in the full light. As

the larve of the Peacock feed on nettles, the stalks of nettles, passing

through small holes in the bottom of well-closed boxes, were received

in vessels of water, so as not to need renewing very often; when

changing became necessary, this was done in a darkened chamber.

Notwithstanding every care no alteration took place in any shade

of the wing of the butterfly.

There is, however, one point of difference which appears well

indicated— the action of light. A small species of the genus

Vanessa, known by the popular name of Carte géographique, from

the pattern of its wings, has two annual generations. In the indi-

viduals the whole of whose metamorphoses take place in the summer

the wings are black: this is Vanessa prorsa. In the individuals

which pass the winter in the pupa state the wings are fawn: this is

the variety levana.— Comptes Rendus, Dec. 16, 1895,

XLVI.—On new Speciesof Coleoptera from Japan, and Notices

of others. By G. Lewis, F.L.S.

TOWARDS the close of last year Monsieur René Oberthiir sent

me some Coleoptera from Oshima, and on examination I find

the species generally are of a decidedly more tropical character

than those of the most southern parts of Kiushiu. I once

spent three or four days in Oshima in February; the diurnal

Lepidoptera were then flying freely, and the temperature and

climatal conditions generally seemed to me to harmonize with

those of May in Nagasaki. Oshima lies in lat. 28°, and

Nagasaki is close to lat. 33°, and the warmth of the ocean,

as well as the more direct rays from the sun, has a very

marked effect on the vegetation of the smail oceanic islands

to which Oshima belongs. Near Yokohama the warmth of

the Kurosuwo, or Japanese Gulf-stream, is distinctly felt on

the Idzu peninsula, while in the bay of ‘Tokio the water is of

a lower temperature ; this and similar agents in various parts

of Japan have without doubt a localizing effect on peculiar

species, and until almost every valley and mountain-side have

been searched at various seasons of the year, the Coleopterous

wealth of the Empire will continue to yield sufficient novelties

to reward one whose care it may be to seek them.

Eustra Batesi, sp. n.

Rufo-testacea, nitida, subdepressa ; thorace minus transyerso, sub-

cordato ; elytris perspicue imbricato-punctatis, disco post medium

infuscato; antennis pedibusque rufo-testaceis.

L. 22 mill.

Reddish testaceous, shining, somewhat depressed; the

thorax feebly explanate laterally, with very minute projec-

tions (but clearly seen under the microscope) at intervals

along the edges, and somewhat wide at the base (fig. 1); the

elytra clearly punctate, punctures shallow and being some-

times transversely confluent have an imbricate appearance ;

on the disk of each elytron just behind the middle is an infus-

cate blotch, more or less defined in different specimens; the

pygidium also has a somewhat similar shallow imbricate

surface-sculpture.

Fig. 1. Fig. 2.

Bates formerly (Trans. Ent. Soc. Lond. p. 237, 1873),

before he saw a Burmese specimen, considered this species to

be E. biplagiata, Schmidt-Goebel, but Jatterly (Ann. Mus.

CivGen..‘ser./25 wol. <n. 4p. 270, 1892) he ealled it Eustra

biplagiata, var. japonica, But it is, without doubt, a distinct

species. Lustra biplagiata, judging from an example from

Burmah so named by Bates and now in the Genoa Museum,

has the thorax very much narrowed behind (fig. 2), without

conspicuous lateral projecticns, and the elytra are also much

less wide, and only “ vage imbricato-punctatis,” as Schmidt-

Goebel described them. ‘The pygidium also is smooth. In

the Genoa Museum there is a third species from Teinzd in

Burmah, in which the head is less elongate, the eyes more

prominent, and the colour and general sculpture different.

Hab. Common in Kiushiu under stones and bark of decay-

ing trees, and it is often gregarious. Also taken at Kashiwagi

and on Maiyasan near Kobé. Some notes on its habits are

given in the Ent. M. M. p. 39 (1881).

Trechus ovipennts, sp. n.

Gracile ovatus, supra depressus, piceo-brunneus, palpis, antennis

pedibusque pallidioribus; capite sat lato, post oculos parum

angustato; thorace ante basin conspicue constricto, angulis

posticis acutis ; elytris ovatis, depressis, striis tenuiter impressis,

interstitiis haud convexis, leevibus.

L. 6 mill.

This species is similar in size to 7. oreas, Bates, in the

Japanese series, but it is darker in colour, much more de-

pressed, head wider, thorax broader behind the anterior angles,

and at and before the base the thorax is conspicuously con-

stricted. The elytra are precisely oval, being rounded off

anteriorly and posteriorly in exactly the same measure, are

very feebly convex, with the striz fine and interspaces nearly

flat and smooth.

Hab, Ontake, August 1881. I obtained only one example.

Pheropsophus agnatus, Chaud. Ann. Soc. Ent. Belg. xix. p. 43 (1876) ;

Bates, Ann. Soc. Ent. Fr. (6) ix. p. 281.

I believe this species is now recorded from Japan for the

first time. Chaudoir described it on a Chinese specimen ;

Bates’s notice refers to varieties.

Hab. Oshima (Oberthiir).

Styphromerus Batesi, Chaudoir.

Styphromerus Batesi, Chand. Ann. Soc. Ent. Belg. xix. p. 87 (1876).

(1873).

Chaudoir in 1876 corrected the nomenclature of this species.

Hab. Nagasaki. Only seen once; this species crepitates

more loudly than any species of Brachinus I have ever met

with alive.

Atritomus Feittert, sp. n.

Oblongo-ovalis, piceus vel nigro-piceus, nitidus; capite, thorace

antennisque nigris; elytris brunueis vel disco infuscato, punctato-

striatis ; pedibus piceis.

L. 23-23 mill.

Oblong-oval, piceous or nearly black, shining; the head

punctate, punctures irregular and not very thickly set ; the

thorax transverse, more thickly punctured than the head, but

the punctures are somewhat sparse before the scutellum,

lateral rim arched and distinctly reflexed; the elytra are

usually wholly brown, but sometimes the dorsal disk is infus-

cate as well as a band along the outer margin, punctate-

24%

Sy Mr. G. Lewis on

striate ; the antenne are somewhat long and nearly black ;

the legs infuscate, with the joints and tarsi rather paler.

This species differs from A. Lewis7, Reitt., in being less

parallel and with shorter elytra. The antenne are one quarter

of their length longer, the thorax is more transverse and more

arched later rally, with the rim conspicuously raised ; the punc-

tures of the elytra are also clearly separate from each other,

and not close and sometimes confused as in A. Lewisi.. The

hind tarsi also are distinctly longer.

Hab. Suyama in Sagam1, and Ichiuchi and other places in

Higo.

Pheochrous asiaticus, sp. n.

Piceo-brunneus, nitidus, supra parum convexus; clypeo margine

utrinque reflexo in medio inciso; thorace sparse punctato; elytris

dense striato-punctatis; tibiis anticis 3-dentatis.

L. 9-94 mill.

Pitchy brown, shining, somewhat convex above; the head

with rather small punctures, not closely set, and a small area

between the eyes smooth, anterior portion and cheeks finely

strigose, clypeus deeply incised in the middle, with the edges

on either side markedly reflexed; the thorax with scattered

punctures variable in size on the disk, larger and closer on

the lateral margin, along the edges is a fine stria, complete

on all sides, but leaving a somewhat wide smooth margin

behind the head ; the scutellum somewhat acuminate, hinder

part smooth ; the elytra has rows of punctures, about twenty-

one, more or less regular, with three vague cost on the

median area; each costa is separated by three or four rows of

punctures ; the anterior tibie have three large teeth on the

outer edge well separated from each other and _ projecting

beyond the regularly arranged smaller ones.

This species differs from a Ceylonese species I have in the

clypeus being more widely incised, the thorax more convex,

the marginal stria leaves a wide margin behind the head,

and the scutellum is longer and more ‘acuminate posteriorly.

In the Ceylonese species the anterior tibie are only furnished

with two conspicuous teeth.

Hab, Okinawa. I have seen three examples from the

collection of Colonel Schénfeldt.

Apogonia amida, sp. n.

Breviter ovata, convexa, nitida; capite thoraceque supra zneo-

nigris ; antennis brunneo-testaceis ; clypeo antice arcuato, dense et

new Japanese Coleoptera. 333

paullo rugose punctato, inter oculos parum sparse punctato ;

thorace sparse punctato, angulis anticis depressis, lateribus

arcuatis.

L. 73-8 mill.

In 1874 Waterhouse considered that this species belonged

to A. splendida, Bohm., but a larger series of specimens now

available for examination proves it to be distinct. The form

of the clypeus is shorter and relatively broader, and it is more

widely arched and consequently wider before the eyes; the

thorax is more transversely convex, and the anterior angles

are more obtuse and depressed and the lateral margin more

arcuate. The punctuation also of the ventral segments is

larger and the pygidium less wide and not carinate in the

middle. The tarsi are longer and more slender. The scu-

tellum is almost impunctate. In some examples the elytra,

metasternum, and ventral segments are brownish, with an

zneous tinge.

Hab. Nagasaki and other places in Kiushiu. There are

examples from my collection in the British Museum and in

the Museum at Brussels.

Apogonia bicarinata, sp. n.

Oblongo-ovata, nigra, nitida, capite thoraceque sat dense et grosse

punctatis ; clypeo arcuato, antice vix sinuato ; scutello sparse sed

distincte punctato; elytris punctatis, singulo in medio bicostato ;

propygidio pygidioque in mediis conspicue carinatis.

L. 10 mill.

Oblong-oval, black, shining, with a very faint cupreous

tint; the head closely but not densely punctate; clypeus

widely arched, with the outline very feebly sinuous or nearly

straight, narrowly and not markedly reflexed at the edge; the

thorax punctured like the head, anterior angles obtuse, not

produced ; the elytra punctate, punctures chiefly in rows, with

two median and one sutural coste on each smooth; the pro-

pygidium and pygidium rugosely punctate, each with a

median carina occupying their whole length; the palpi and

antenne brown or testaceous. ‘The anterior tibiz are pro-

longed beyond the tarsi (except in Schonfeldt’s example,

which is malformed), but they are not conspicuously dentate

like others of this genus.

This species differs from A. splendida, Bohm., in colour,

being concolorous throughout, in the form of the clypeus, in

the scutellum being punctured, and, above all, in the pro-

pygidium and pygidium both having a carina.

Hab. Japan (Ritsema), Oshima (Schdnfeldt). The type

specimen belongs to the Museum of Brussels.

Apogonia cupreoviridis, Kolbe, Arch. f. Nat. i. p. 193 (1886).

Apogonia fusana, Kolbe, 7. ¢. p. 198.

I find I have an example of this species from the Goto

Islands; it should therefore be included in the Japanese fauna.

It is much larger than A. niponica, Lew., anterior angles

less acute, and the punctuation of the thorax is larger and not

dense.

Hab. Gotoshima and Korea (Kolbe).

Anomala Gottschei, Kolbe, 1886,= Anomala geniculata,

I inadvertently omitted Kolbe’s name in the synonymic

list of last year.

Chalcophora satzume, sp. n.

Afneo-nigra, nitida; capite in medio canaliculato; thorace post

angulos paullo prominulo; elytris obscure 4-maculatis, apicibus

conspicue incisis.

L. 32-34 mill.

There are several good characters to separate this species

from C. japonica, Gory, which it resembles closely. It is

broader, less parallel at the sides, and darker in colour. The

thorax bulges out somewhat behind the anterior angles and

the apices of the elytra are sharply incised ; the eyes are more

oval and less convex, and the dorsal area flatter, with the

smooth elytral spaces less elevated. There is an example of

a species very similar to C. satzume in the British Museum

from Chinkiang on the Yangtsze River; the apices of the

elytra are incised and the thorax bulges out in a similar

manner, but the Chinese species has the elytral convex spaces

more like those of C. japonica.

or not Saunders could not decide, and it cannot be determined

until the type is examined,

L. 102 mill.

The head rich golden green, frontal channel deep, not

angulate behind, punctate, punctures deep and elongate,

especially lengthening (almost furrow-like) before the neck,

where they are generally transverse ; the thorax coarsely and

transversely sculptured, feebly arched in outline from the

anterior angle to the base, edges crenulate, sides somewhat

explanate at and before the bases, rich blue on the disk and

base, golden green laterally and blue-green behind the neck ;

the scutellum, anterior portion transverse, with sharply defined

truncate sides, and an acuminate triangular area behind,

median space rugosely punctate; the elytra, sculpture

distinctly transverse and somewhat coarse, golden green at

the base, narrowly only near the suture, but at the humeral

angle the green colour stretches out broadly along the sides

almost to the middle of the wing-case, at the apex about one

fourth of the elytral length is golden green, the central area

coppery red, and this colour extends along the suture nearly

to the base; across the coppery dorsum is a rather wide white

pubescent fascia, with a white patch in front of it near the

suture, the apex is 4-spinose, two on each elytron, the outline

of the elytral edge between the spines is narrow and semi-

circular (in C. niponicus this outline is wide and nearly

straight) ; the ventral segments above are of a deep rich blue,

beneath the whole body is obscurely eneous and pubescent,

and the antennze and legs concolorous.

This species is the size of C. niponicus, Lew., and should

be placed next to it in the Catalogue.

Hab, Oshima.

It gives me much pleasure to name this species after

Mons. René Oberthiir, from whom I received it.

Lacon, Castelnau.

A sexual character in the males of certain species of this

genus has been noticed by Champion (Biol. Centr.-Amer.

vol. ii. pt. 1, p. 263, 1894). In some species the males have

an almost smooth space on the fifth ventral segment, varying

in size in different species. I find this character in two

Japanese species: in L. cordicollis, Cand., the male has a

smooth disk equal to nearly one third of the ventral area; the

space leaves a narrow margin only at the apex and anteriorly

it does not reach beyond the middle. In ZL. binodulus,

Motsch., the smooth space is further from the apex, is some-

what triangular, and extends to the base. I have not found

any corresponding character in L. fuliginosus, Cand., nor in

L. 4-nodatus, Lew., and I believe my single example of the

latter is a male. The golden hair which forms the clothing

of L. 4-nodatus is very short and curved, and under the

microscope 1s seen to be cirriform.

thorax, but the rugosity is best marked at and near the

apices ; the sides of the metasternum are densely clothed with

white pubescence ; the mouth-organs, antenne, and legs are

The two curious elytral carinew distinguish this species

from most, if not all, of the described species of Apate; but

Mr. Gorham has a species from the Andaman Islands which

closely resembles it. Its chief differences are, the antennz

are shorter and stouter, the thorax parallel at the sides,

rectangular at the base, the scutellum not elevated, and the

two elytral carine are half as long again; both species

measure L. 13 mill. In the Andaman species the tarsi are

also shorter and the terminal joint of the antenna is conical.

In A. carinipennis the terminal joint is distinctly oval *.

sutural margin is elevated, and there are two median rather

vague coste separated from each other by three rows of

punctures, and well before the apices at an equidistance from

the suture and outer edge are two large tubercles, one on each

nide (Ann. & Mag. Nat. Hist. ser. 6, vol. xii. p. 484, 1894),

nor does the name appear in the ‘ Zoological Record’ of

1876. The species only measures 7 mill., and is described

doubtfully as belonging to Helops.

Plesiophthalmus brevipennis, sp. n.

Subelongatus, niger, nitidus, leviter convexus; capite rugose punc-

tato ; thorace subtilissime punctulato ; elytris subtilissime striato-

punctatis ; antennis pedibusque obscure rufis.

L. 134 mill.

Black, shining, with a slight bluish tint, antenne and legs

dull red; the head rugosely punctate, lateral ridges, under

which the antenne are inserted, distinctly elevated; the

thorax rather wider than broad, anteriorly rectangular, ante-

rior and lateral margins finely but clearly raised, surface

polished, with a very fine sparse punctuation, most sparse on

the disk ; the elytra relatively short as compared with P. nigro-

cyaneus, Motsch., highly polished and very finely striate-

punctate, interstices very feebly (almost obsoletely) convex,

with a punctuation sparse and very fine. ‘he male has the

last ventral segment emarginate.

The type of this species is much smaller than any example

of P. nigrocyaneus 1 have seen, and possibly the sculpture

and colour of the body and legs may vary as much as in that

species ; but still there are three good characters by which it

may be recognized, viz. the greater elevation of the antennal

ridges, the feeble surface-sculpture, and the shorter elytra.

Lagria notabilis, sp. n.

Nigra, nitida, nigro-hirta; capite thoraceque grosse punctatis ;

elytris dense punctatis et transversim rugosis, apice angulo sutu-

rali valde mucronatis.

L. 114 mill.

Black, shining, clothed with long black hairs not closely

set; the head and thorax relatively narrow, elytra at the

bases as wide again as the thorax, widest behind the middle ;

the head rather coarsely and rugosely punctate, with a trans-

verse impression between the antenne ; the thorax sculptured

like the head, with a longitudinal impression, free of large

punctures, on the disk; the scutellum somewhat roughly

punctulate, obtuse behind; the elytra more densely and more

coarsely sculptured than the thorax, with the interstices of

the punctures more raised and generally distinctly transverse ;

on the apex of each elytron there is a large triangular process,

the base of the triangle being parallel to the suture, so that

when the wing-cases are closed only one of the processes is

visible; the antenna and legs are black, joints 7 to 11 of the

first are opaque.

Hab. Oshima (Ferrie).

Macrolagria rugipennis, sp. n.

Elongata, subparallela, nigra, nitida; elytris grosse et rugose

punctatis, nigris vel rufo-brunneis,

L. 11-12 mill.

Elongate, rather parallel at the sides, black, shining ; the

elytra black or wholly reddish brown; the head smooth, with

a very few scattered punctures and an oblong impression

between the eyes (not always well defined) ; the thorax, punc-

tures larger and much more numerous than those of the head

and somewhat irregularly set, posterior rim distinctly elevated ;

the elytra with coarse punctures arranged roughly in double

rows, with coste running between them; the coste are

encroached upon by the punctures, apices somewhat acute ;

the legs and antenna: black.

This species is about the size of and similar to MZ. rufo-

brunnea, Mars., but the eyes are nearer together in both

sexes and the rough and coarse sculpture of the elytra is

very different.

Hispa higonia, sp. n.

Oblongo-quadrata ; capite rufo; thorace transverso, 5-spinoso ;

elytris multispinosis, abdominis pedibusque rufis.

L. 4 mill.

The head red, microscopically rugose before the eyes; the

antenne filiform, basal joint rather long, first two and the

last blackish; the thorax transverse, margins reddish, with ared

median line, two spines on the edge behind each eye having

a common base and are nearly erect, on the lateral margin

are three spines having also a common base, surface punctate,

but less coarsely than that of H. japonica, Baly ; the scutellum

blackish, with a red median mark; the elytra, each furnished

with about twenty spines, those on the dorsum are erect,

surface with rows of large punctures evenly set, colour pitchy,

with the posterior edge rather broadly, lateral edge indistinctly

reddish testaceous, and marks of the same colour on the wing-

cases ; the legs and abdominal segments reddish.

The facies of this insect resembles H. japonica, but the

basal joint of the antenna is half as long again, the eyes are

wider apart, and instead of tuberosities on the dorsum it has

long spines, and the anterior tibia are less swollen.

By ALFRED O. WALKER.

[Plate XVI.]

Fam. Phoxocephalide, G. O. Sars.

Phoxocephalus pectinatus, sp.n. (Pl. XVI. figs. 1-6.)

Kpimeres of the perzon rather deeper than their segments ;

third pleon-segment with the lower margin straight, the hinder

slightly convex, and the hinder angle with the point rounded.

Head with the hood slightly curved downwards; eyes

round, dark, and large, especially in the male.

Upper antenne with the first joint longer than the two

next, its upper margin produced and the lower furred in the

male ; flagellum 4-jointed, terminated in the male by a stiff

seta as long as the whole antenna; accessory appendage

4-jointed, reaching nearly to the third joint of the flagellum.

Lower antenne in the male as in P. Holbélli, in the female

with the second joint of the peduncle nearly as long as the

first and third together ; flagellum 4-jointed, as long as the

second joint of the peduncle.

First gnathopoda rather smaller than the second ; epimeres

distally expanded; propodos distally contracted; second

gnathopoda with the epimeres rounded-oblong ; margins of

propodos parallel ; in both pair the propodos is almost as long

as the four preceding joints, the second, third, and fourth

joints being very short.

First and second pereeopoda much as in P. Holbélli, but

with the dactylus about three fourths of the length of the

propodos.

344 Mr. A. O. Walker on Two new

Third and fourth pereopoda as in P. Holbélli, except that

the latter is rather longer.

Last pereeopoda with three shallow teeth on the hind

margin of the first joint ; second and third joints in the female

with long plumose sete, remaining joints gradually decreasing

in length. In the male the fourth joint has four curved

and blunt spines in an equidistant comb-like row on the

distal half of the anterior margin; the third joint has no

plumose setz.

Uropoda and telson nearly as in P. Holbélti, but there are

no spines on the longer ramus of the third uropoda.

Length 3 millim.

This species may be at once distinguished from Pho.o-

cephalus Holbélli, Leptophoxus falcatus, and the genus Har-

pinia by the conspicuous eyes, while the shortness of the first

four jomts and the form of the hand in the gnathopods, as

also the characters of the last pair of pereeopoda, distinguishes

it from Paraphoxus oculatus and Phoxocephalus Fultont. A

male and female were dredged by me off St. Peter’s Port,

Guernsey, in 7 fathoms, on a bottom of coarse gravel, clinkers,

and broken shells, on April 4, 1892. I have also received a

male from Mr. J. T. Calman, University College, Dundee,

who informs me that it was tound with a few others among

a number of male P. Fultont, Scott, received from Mr. D.

Robertson, of Cumbrae, some years ago.

Fam. Pardaliscid#, Boeck.

HALICOIDES, gen. nov.

Head with a rostrum equal to half the entire head; eyes

obsolete.

Upper antenne with no accessory appendage at the base of

the flagellum, but with a small one at the base of the last

(third) joint of the peduncle.

Mandibles nearly as in Halice, but with the last joint of the

palp about two thirds the length of the second joint and more

slender.

Gnathopods simple.

First and second pereopods with the third and fourth joints

expanded.

Remaining characters as in Halice.

Halicoides anomala, sp.n.(¢). (PI. XVI. figs. 7-18.)

Epimeres of pereeon small; first three pleon-segments with

a small tooth at the hinder angle, fourth and tifth injured,

but with no appearance of dorsal teeth.

Species of Amphipoda Gammarina. 345

Head longer than the first two body-segments ; eyes indi-

cated by a clear almost circular space on the top of the head.

Upper antenne with the first joint very large, expanding

distally, and completely filling the space between the rostrum

and the anterior margin of the head, exceeding in length the

next two joints, which are less than half as wide; the distal

margin of the second joint has a sinus on the upperside, from

which a scale-like appendage reaches to the end of the upper

margin of the third joint, which is much shorter than the

lower margin. First joint of flagellum as long as the last

two of the peduncle, furred, and provided with long sete on

the upperside; next eight or nine joints very short, setose,

tapering gradually into longer and thinner joints, about twenty-

eight in all.

Lower antennee :—Penultimate joint of peduncle reaching

to the end of the first joint of the flagellum of the upper

antenne, constricted at the proximal end; last joint longer

than the preceding, both with setules along the upper margin ;

flagellum very slender, with the third joint longer than the

preceding and succeeding joints, about twenty-eight in all.

First gnathopod:—First joint thicker than any of the

following, about as long as the next three; carpus rather

more than half as long as the propodos, which tapers gradually

to the base of the dactylus, and has three sete and six setules

on the lower margin ; the dactylus is expanded at the base,

not deflexed, and fully half as long as the propodos. Kpi-

mere subtriangular.

Second gnathopod :—Like the first in general form, but the

lower margins of the carpus and propodos are furred and

densely clothed with sete, which lengthen distally; many of

those on the carpus are greatly curved. Epimere rounded-

oblong.

First and second pereeopoda :-—First joint as long as the

third and fourth together, third obcordate, the distal end as

wide as the shorter diameter of the broadly oval fourth joint ;

fifth joint as long as, but much narrower than the fourth;

dactylus about two thirds the length of the fifth joint; hind

margins of third, fourth, and fifth joints fringed with long

sete, which are most numerous on the fourth.

Third pereeopoda :—First joint twice as wide and not so long

as the third, which is about equal to the fourth and fifth, but

twice as wide. Dactylus more than halt as long as the

propodos.

Fourth and fifth pereeopoda subequal, of the same form as

the third, but much longer.

Branchial vesicles and pleopoda large.

346 On Two new Species of Amphipoda Gammarina.

Uropoda injured, the first with peduncles as long as the

rami, which are narrow, equal, and spinous; the second

shorter than the first, with subfoliaceous (?) rami; the third

foliaceous and probably setose, the inner ramus rather shorter

than the outer, which is coarsely serrate on the inner side and

is terminated by a short strong spine. The peduncle is

short, widening distally, with a median and terminal spine.

Telson longer than the peduncle of the last uropoda, cleft

to the base, with a notch at the tip of each division.

Length 7 millim.

A single male specimen was found in a very interesting

collection of Crustacea made by Mr. R. L. Ascroft in the

steam trawler ‘ Britannic,’ off the Isle de Yen, in the north of

the Bay of Biscay, the depth being 17 to 32 fathoms, bottom

sand and mud. ‘This species approaches the genus /alice,

Boeck, very closely in general form, structure of the mouth-

organs, antenne (with the exception of the accessory ap-

pendage), gnathopoda, last three pair of pereeopoda, uropoda,

and telson; but it differs from that genus in having no acces-

sory appendage at the base of the first joint of the flagellum

of the upper antenne, and from every known Amphipod, so

far as | am aware, in having a smal] but distinct scale-like

accessory appendage at the base of the last (third) joint of the

peduncle. Both the upper antenne are exactly alike in this

respect. The first and second pairs of pereeopoda resemble

those of the genus Synopia, Dana, in the dilated third and

fourth joints, and thus connect this genus with the Parda-

liscide in this respect, just as Synopioides, Stebbing, does in

the shape of the head. There remains, therefore, nothing to

justify Bovallius’s establishment of the subtribe of Amphipoda

Synopidea,—Claus, Stebbing, and G. O. Sars having already

pointed out the relationship of the titular genus to the Gam-

marina, and the remaining genera having been referred to

other families, viz. Trischizostoma to the Lysianasside and

Hyperiopsis to the Hyperiidea.

On the Piertne Butterflies of the Genus Daptonura. 347

XLVIII.—Notes on the Pierine Butterflies of the Genus

Daptonura, with Descriptions of new Species. By A. G.

Butter, Ph.D., Senior Assistant-Keeper, Zoological De-

partment, British Museum.

In carefully supervising the synonymy of Daptonura I noted

that the outline of the wings, the width of the outer borders,

and the inner edging of the latter appeared to be constant and

reliable characters; but the mere tint of the wing-surface

varied from white to brimstone and from brimstone to saffron,

these modifications being best illustrated by such species as

D. florinda and D. isandra.

In D. limnoria, Godt. (limnobia, Swains.), the secondaries

of the male vary in tint from pale brimstone to canary-yellow,

but the orange on the border is invariably represented by a

series of saffron or orange spots. Hiibner’s figures (Samml.

exot. Schmett. ii. pl. ccxxxii.) represent a very distinct

species, for which, years ago, I proposed the name D. Hiibner?,

writing it upon a label and pinning it into the collection; but

if I published the correction it has never been quoted, and

consequently I cannot refer to it.

Hiibner’s insect differs in both sexes from D. limnoria,

as will be at once seen by comparing Swainson’s admirable

illustration of the latter with the plate in the ‘Sammlung.’

Daptonura Hiibnerv.

3. Decidedly smaller than D. limnoria, the black apical

border narrower, with regularly dentate-sinuate inner edge ;

the secondaries bright sulphur-yellow, with broad orange

outer border and linear black edging.

@. Smaller than that sex of D. “imnoria, the black cunei-

form bar across end of cell connected by a streak (which

passes along the third median branch) with the black outer

border ; the latter narrower on the costa than in the common

species and gradually decreasing in width to inner margin ;

the secondaries as in the male, excepting that the orange

external area and black edging are wider.

The female I know only from Hiibner’s illustration ; it is

said to come from Brazil. The locality is probably Rio Real

in Northern Bahia.

Daptonura inequalis, sp. n.

Allied to D. leucanthe ; decidedly smaller, the outer margin

348 Dr. A. G. Butler on the

of primaries straighter, the black apical border decidedly

narrower, with zigzag dentated inner edge; only the fringe

of secondaries (not the margin also) blackish ; male above

white, female bright orange washed with canary-yellow on

costa and in cell of primaries: the male below nearly resembles

D. leucanthe, but the blackish line on the end of the dis-

coidal cell of primaries is either ill-defined or wanting ; the

apical border also is only indicated through the wing and the

veins crossing it are barely or not at all blackened; the apical

area of these wings and the whole surface of secondaries are

far more buff in tint, and the veins of the latter wings are

black to the base; the wings themselves are more rounded,

less produced at anal angle than in D. leucanthe: the female

below is paler (more golden crocus-yellow) than above, in

veining it corresponds with the male.

Daptonura latilimbata, sp. n.

g. Allied to D. peruviana; basal two thirds of primaries

milk-white ; costal margin and apical third black-brown, the

inner edge of the latter zigzag, commencing almost parallel

to the end of the cell and continued obliquely to near the

extremity of the first median branch, whence it tapers more

abruptly to the extremity of the submedian vein; fringe

towards external angle white: secondaries milk-white, with

black-brown outer border as wide as in the female of D. eu-

rymnta, but not spotted: body normal. Wings below with

the black-brown borders broader, shining dark copper-brown ;

a black-brown cuneiform streak from costa closing the dis-

coidal cell of primaries; basal lobe of secondaries orange,

and sides of pectus washed with the same colour as in

D. peruviana.

Daptonura Harti, sp. un.

Commonly confounded in collections with the New Grana-

the outer margin of primaries more concave; the external

border of these wings in the male slightly narrower, especially

below the second median branch, the inner edge of this border

widely sinuous, but not regularly sinuated as in the New

Granadian species: the secondaries tinted with sulphur-

yellow; the dark brown outer border much narrower,

tapering to a point at each extremity, so that only three out

of the usual five squamose whitish submarginal spots are

clearly emphasized : on the under surface the brown borders

differ as above, and the yellow is a clear brilliant canary

instead of gamboge; the basal lobe of secondaries is barely

tinted with saffron, instead of being deep orange. In the

female the differences are less marked, but the primaries above

are pale brimstone and the secondaries bright brimstone-

yellow, far brighter than in D. eurymnia: on the under

surface the borders are slightly narrower than in the female

of the latter species, the primaries are brimstone-yellow, with

the costal area deepening to canary ; the secondaries are very

deep canary-yellow, with a slight tint of saffron on the costal

edge of the basal lobe, whereas in D. eurymnia these wings

are much darker, cadmium-yellow, with deep saffron basal

lobe.

Eixpanse of wings, ¢ 58-70, 9 59 millim.

Trinidad (art, Broadway, and Caracciolo). B.M.

Judging by the female differences alone, I should never

have supposed this to be a distinct species; but the male

characters are much more markedly dissimilar from the form

of the mainland; the latter ranges from Bogota to Venezuela,

but whether to the coast I do not know.

The true D. eurymnia is like a white edition of D. poly-

hymnia, and | am satisfied that the two are only forms of

one species ; in like manner I still believe that D. monstrosa

is only a form of D. jlorinda, inasmuch as the fact that

Dr. Staudinger has described four types, all differing, clearly

indicates inconstancy in the ground-colourig of the wings.

The Hewitson collection contains a male and two females,

none of which agree with the figures in the ‘ Biologia’—they

are all what botanists know as “selfs.” ‘Then, again, the

D. panamensis of Staudinger is represented by the opposite

sexes of the two forms D. flurinda and D. monstrosa, as

figured in the ‘ Biologia,’ the male being described as having

the primaries white and the secondaries citron-yellow, the

female as having the primaries citron and the secondaries

ochre-yellow.

Staudinger’s D. anceps is said to be smaller, the secondaries

white, like the primaries, but with a yellowish suffusion at

350 Mr. H. Druce on new

the anal angle; the ‘female more opaque than in D. pana-

mensts, not ochre-yellow on the secondaries ; therefore this

female would answer to the female of “ D. panamensis”

figured in the ‘ Biologia.’

Staudinger’s D. chagris is said to resemble his D. pana-

mensis in both sexes, excepting that it has a somewhat

broader black apical border and the under surface of the

primaries is white with yellow costal border.

Staudinger’s D. chiricana is a “ self,” the male citron and

the female ochre-yellow ; it corresponds exactly with a pair

so-named in the Hewitson collection *, which I am satisfied

are conspecific with D. florinda; whilst Hewitson’s third

example is gamboge-yellow, and therefore is intermediate

between D. anceps 2 and D. chiricana ¢ .

As another instance of variation in ground-colour in this

genus I may mention that I have no doubt of P. pedrosina

being a mere form of P. palestra, differing in having the

secondaries and costa of primaries on the under surface white

instead of yellow; there is no other difference by which to

separate them.

My D. pedrosina, therefore, will sink asa seasonal form or

a sport of D. palestra, Hopffer.

only 1545 inch in expanse of wings, whereas the expanse of

eryx is 17%; the upperside is duller in colour, the blue sheen

more restricted on the hind wings; on the underside the

markings are similar, but the ground-colour is dull pale

ochreous yellow, instead of dark bright green, as in eryz.

The type specimen (a female), which is in the Indian

Museum, Calcutta, came from Cachar.

Tajuria valentia, sp. n.

de Nicé., covering all the wing except the cell and space

below the first median veinlet ; in other examples there is

some blue in the outer interspace above: hind wing with the

costal border black, fining downwards round the apex to a

fine line on the outer margin; abdominal space nearly pure

white ; tails black, with white tips ; anal lobe small, with a

blackish outer patch and a fine white thread running up a

short distance on the outer margin; cilia black, with white

differently placed, being much further in, colour different,

being reddish brown, whereas in mantra it is merely of a

darker shade of the ground-colour. TZ. mantra has also an

Hew. ; costal and apical band black and very deep, limited by

the median vein, and then broadly down the outer margin to

just below the first median veinlet, where it is rounded off in

some examples, leaving the remainder of the margin with a

fine black line; in others it reaches the hinder angle and

curves a little on to the hinder margin. Hind wing with a

broad blackish-brown costal margin, limited by the subcostal

vein; the costal space pale and in some examples nearly

white; outer marginal line black, with three submarginal

blackish spots in the interspaces near the anal angle; tails

anal lobe with a black spot crowned with orange; abdominal

space whitish, the white hairs often hiding the orange on the

anal lobe. Underside grey, paler than in 7’. longinus, Fabr.,

but not so white as in 7. dius; very similar to longinus in

its markings; the discal transverse line is, however, more

flexuous and curves in on to the costa in both wings at a

greater distance from the apex than in longinus ; there is also

on both wings an indistinct grey submarginal line and an

indistinct grey band between this line and the margin; a

black spot on an orange ground in the first submedian inter-

space near the margin, another crowned with orange on the

anal lobe, with a pale lunular mark ona grey ground between

them.

364 Mr. R. M‘Lachlan on Odonata from

LI.—On Odonata from the Province of Szechuen, in Western

China, and from Moupin, in Eastern Thibet. By Ropert

M‘Lacu3ayn, F.R.S. &e.

In the Ann. & Mag. Nat. Hist. for May 1894 I published

(pp. 421-436) a notice of Neuroptera from Ta-chien-lu, in

Szechuen, received from my friend Mons. René Oberthiir.

Since then the same kind friend has sent me a further collection

from other neighbouring localities in the same province and

also from Eastern Thibet. They are principally Odonata,

and I do not here propose to notice the few insects of other

groups of Neuroptera, neither do I intend to include some

few species present in both consignments where there is

nothing of interest in connexion with them. In the following

pages several new species are described and previously

unknown sexes of others, also notes of local and general

interest. As previously noticed, the affinities are with Japan

and North China.

Subfam. Drperzvrra.

Thecadiplax ardens, M‘Lach.

A series of individuals of both sexes from Moupin agree

with those previously described from Ta-chien-lu. Further-

more, several specimens taken by my friend Mr. J. J. Walker

in the Chusan Archipelago and on the neighbouring coast of

China seem also to belong here, independent of the question

of specific right or as representing a race of Th. erotica, Selys.

[N.B.—This appears a fitting opportunity for a short

statement with regard to Thecadiplax infuscata, Selys, and

Th. erotica, var. fastigiata, Selys.

Th. infuscata was originally described by my friend Baron

de Selys (Ann. Soc. Ent. Belg. xxvii. p. 90, 1883) from a

pair (¢ ¢) in my collection, the female of which had lost the

end of the abdomen. Th. erotica, var. 9 jfastigiata, was

noticed at p. 91 of the same volume of the ‘Annales.’ In

both of these the apical portion of the wings is smoky or

blackish.

In the same ‘ Annales’ for 1884, p. 40, Baron de Selys

doubts whether the individuals described as a variety of the

female of erotica under the name fastigiata should not more

properly be considered zxfuscata, and he expresses some

Western China and Eastern Thibet. 365

doubts as to whether the abdomen and head of the original

male type of infuscata might not have been accidentally

broken off and replaced by that of some other species. It

appears to me practically certain that Th. ¢nfuscata and the

var. fastigiata are specifically identical and distinct from erotica.

I can state positively that the head and abdomen of the

original male of infuscata have never been detached and also

that the two small steel-blue spots are present (contrary to

what is stated in the original description) and less rudimentary

than those in the original female type. Furthermore, I have

since received another male agreeing perfectly with the

original in wings, genitalia, and appendages, but in this

individual the two steel-blue spots are absent.

Thecadiplax is made up of incongruous materials, and it is

probable that the large and ponderous Th. baccha, Selys, may

form a group by itself; of this the female is at present not

known to me, but 1 possess three males taken by Mr. J. J.

Walker in the Chusan Archipelago and vicinity.

Here, also, I allude to the solitary male insect from Ta-

chien-lu mentioned in my former paper (p. 432) as ‘¢ Agriono-

ptera(?), sp.” In this insect there are symmetrically two

nervules in the median area ot the posterior wings (one

forming the inner triangle and one other), and in the same

wings the arculus is symmetrically not coincident with the

base of the triangle, but placed distinctly (though not distantly)

more towards the base. ‘These characters induced me to think

ot Agrionoptera as a possible, though doubtful, location.

Further examination causes me to think its position is near

Thecadiplax infuscata, although the characters just alluded to

are foreign to such a connexion. ‘The general form is not

opposed to such a position: there are only ten antenodals (the

last not continuous) ; the extreme apex (after the end of the

pterostigma) of all the wings is infuscated, and the genitalia

and appendages do not apparently differ from those of Th. in-

fuscata. ‘The top of the face is unspotted (the form of the

prothorax it is not now possible to define). Whether this be

a case of individual aberration, or whether it is indicative of

a group in which there is plasticity of neuration as well as of

other characters usually considered essential, further materials

can alone decide. |

Orthetrum internum, M‘Lach.

Orthetrum japonicum, var. internum, M‘Lach. Aun. & Mag. Nat. Hist.

May 1894, p. 431,

In my former paper I gave certain characters separating

366 Mr. R. M‘Lachlan on Odonata from

this from typical O. japonicum, Uhler. The only one of any

importance was that the triangle of the posterior wing appeared

to be constantly traversed by a nervule in énternum and con-

stantly free from such nervule in japonicum. Having

examined more examples, the same rule appears to hold good,

and as such a character when constant is regarded as of

specific importance, I here quote ¢nternwm as a species. In

some females of japonteum the middle lobe of the labium is

dusky. As before, it is difficult to define any differences in

the genitalia.

U. internum occurs also in the Khasia Hills and in other

localities of the North Indian side of the Himalayas.

Orthetrum melania, Selys.

A series of examples from Siao-Lou and also from Moupin,

the latter showing a still further western extension of the

species. The male previously noticed from Ta-chien-lu was

highly adult and pulverulent; those now before me are

mostly immature, allowing a comparison as to colours and

markings with the Japanese types. No differences are appa-

rent in the colouring of the body; it is, however, probable

that the dark space at the base of the wings often remains

yellowish (not dark brown) in continental examples.

Crocothemis servilia, Drury.

A series of males from Moupin are remarkable for the very

dark, almost brownish, base of the wings, the colour being

also sharply delimitated on the posterior wings; the neura-

tion is dark and the apical margin is usually narrowly dusky.

T have similar examples from the coast of North China.

These examples induced me to go through, probably for the

sixth time, a series of about one hundred specimens of Croco-

themis. "They were attacked primarily with the idea of finding

specific, or strongly racial, characters in the specimens above

referred to, and secondly to test the possibility of separating

C. servilia and C. erythrea.. Neuration and the genitalia of

the second segment were especially examined.

It is easy to say that large examples from Hong Kong or

Japan are servilia, and that smaller ones from Europe, Africa,

India, &c. are erythrea, and it is tolerably easy to isolate

examples intermediate as to size, such as those from Moupin

&c.; but once again have I failed to find any certain sétruc-

tural characters. There are slight neural differences, but only

such as are either individual or correlated with size, and there

Western China and Eastern Thibet. 367

are slight differences in the genitalia even in individuals from

the same locality, but in the majority of cases of a nature

more illusory than real. Some other investigator may be

more fortunate.

Subfam. Gompurna.

Gomphus scissus, sp. n.

?. Head shining black; a spot on each side of the face at

the corners of the mouth, a rather broad transverse band at

the top of the front, and a small triangular spot at the back

of the middle of the occiput yellow ; occiput strongly ciliated,

produced in its middle into an erect flattened tooth, which is

broad and triangular at its base, but afterwards strongly

acuminate, the apical portion narrow, the apex itself obtuse and

slightly bifid. Prothorax black, with a transverse nearly

interrupted median spot, followed by a short line. Thorax

black above, with grey pilosity, anteriorly with two trans-

verse yellow lines (forming the collar), separated by the

dorsal crest ; behind these is an oblique ¢solated short yellow

band on either side of the dorsal crest, and a small isolated

yellow spot below each band placed more outwardly ; two

small yellow dots in the sinus; in the interalar area are three

yellow spots: sides yellow, a black line on the interalar

suture, connected anteriorly with a much angulated black

line which extends nearly across the pectus, which latter is

otherwise yellow. Legs short, wholly black. Abdomen

dilated at the base, but afterwards slender, black, marked

with yellow as follows :—above, a transverse spot on the

first segment, followed by a median longitudinal band on the

second; a fine interrupted dorsal line on the third, continued

as a short basal line on the fourth to seventh, and a narrow

ring at the apex of the ninth. Sides marked as follows :—a

broad band on the first and second segments, continued as a

narrower band on the third (interrupted in the middle by the

false suture), a small basal and postmedian spot on the fourth

to eighth, and the lateral margins of the eighth and ninth.

Appendages about as long as the tenth segment, cylindrical,

acute, yellow, tipped with black, a rounded black protuberance

between them ciliated with black. Vulvar scale two thirds

the length of the ninth segment, black, divided almost to the

base into two long slender parallel spines, the apices of which

are slightly upcurved.

Wings hyaline, strongly tinged with yellow to beyond the

triangles in the anterior, and nearly up to the nodus in the

stigma long (34 millim.), yellowish brown; 14 antenodal and

13 postnodal nervules in the anterior wings.

Length of abdomen, 9 40 millim.; length of posterior

wing, @ 35 millim.

Siao-Lou (Szechuen), one female.

Notwithstanding that the male remains unknown, there

can be little doubt that this species is allied to G. melenops,

Selys, and G. Pryert, Selys, both from Japan. Both of

these show an analogous conformation of the occiput, but in

a much less pronounced manner, and are of the same general

aspect but larger. ‘The condition of the vulvar scale in

G. scissus is remarkable.

Subfam. CorpvLEGASsTRINA.

Anotogaster Sieboldit, Selys.

Moupin, one male, two females.

These seem to possess some slight differences when com-

pared with numerous examples from Japan and North China.

The two yellow spots at the base of the labrum are appa-

rently smaller; the yellow in the excavated portion of the

top of the front is reduced to a mere marginal thread (virtually

obsolete in one very adult female), and the wings of the

female seem more strongly washed with yellow up to the

triangles, almost as in A. nipalensis and A. basalis. Possibly

the stature is slightly less robust. It would be necessary to

see more materials before deciding if the differences alluded

to are constant and worthy of the imposition of a varietal

name.

Cordulegaster luniferus, Selys, and var. pekinensis, Selys.

Four males and two females from Siao-Lou, Mo-si-mien,

aud other localities in Szechuen. Of these I should be

inclined to refer three males to /wniferus and one male and

two females to peknensts, irrespective of locality, according

to description. Having now so much more material before

me, the distinctness of lunzferus and pekinensis seems very

doubtful. I have seen no male so large as is indicated for

pekinensis.

uniformly pale greenish yellow, margined with blackish at

the summit ; top of the front excavated, its margin broadly

blackish, which colour descends in the middle, forming a

very ill-defined T-spot, the blackish colour blending with

somewhat livid side-spots; vesicle black; eyes connected

in a long space, occiput forming a small black triangle.

Thorax black, above with two broad greenish-yellow bands,

interrupted posteriorly by the sinus; the sides with two

broad oblique greenish-yellow bands, one under each wing;

probably some pectoral yellowish spots. Legs black. Ab-

domen with the first and second segments considerably

dilated; oreilettes not prominent, flattened, yellow, with

about three blackish marginal teeth; general colour dull

blackish, becoming deeper black towards the apex, with indi-

cations of livid (blue or green during life?) markings as

follows :—a broad lateral band and an indistinct dorsal band

on first and second segments, a narrow margin posteriorly to

the second to sixth, a broader submedian band (or semi-

annulus) on the third to eighth placed just below the false

suture; tenth segment above with a rather strong longitu-

dinal median carina, dilated posteriorly into a very strong

laterally flattened triangular tooth directed slightly towards

the apex. Superior appendages scarcely so long as the ninth

and tenth segments united, black ; viewed from above they

are narrow at the base, afterwards gradually dilated internally

to the apex, which is very obtuse and slightly excavated, the

opposing apices touching; the median longitudinal carina

only faintly indicated, merging into the thickened apical

portion ; the inner edge fringed with long blackish hairs in

the median portion : “viewed laterally these appendages are

straight, narrow at the base; subsequently the upper and

lower edges form carine, the upper just before the apex

becoming suddenly dilated and rounded (excavated above),

and the lower ends in a short beak-like process, slightly

upcurved, causing the entire apex to have a striking resem-

blance to the profile of the head of some kind of bird (e. g.

Regulus, with the crest not erected). Inferior appendage

fully two thirds the length of the superior, gradually acumi-

nate, its apex apparently entire, slightly upcurved if viewed

laterally ; above deeply concave and brownish black, beneath

black.

Wings hyaline; membranule white; pterostigma black,

small (3$ millim. in anterior, shorter in posterior wings),

then two rows, followed by three, and increasing; subnodal

sector furcating on a level with the pterostigma (slightly

before in the posterior) ; posterior wings with 12 ante- and

postnodal nervules ; 2 supra-trigonal and 2 in the principal

triangle; anal triangle with 3 cellules.

Length of abdomen (cum append.) 54 millim.; length of

posterior wing 48 millim.

Moupin, one male.

It is probable that the nearest ally of this well-marked

species is the Japanese 4%. melanictera, Selys, which it

resembles in the possession of the strong tooth on the tenth

segment, and there is some amount of affinity in the structure

of the apex of the superior appendages; but the small

size, very small pterostigma, much shorter appendages &c.

cf the present insect are opposed to any very close rela-

tionship. The remarkable bird’s-head-like profile of the end

of the superior appendages is reproduced to some extent in

the European 4. cyanea and the North-American 4. con-

stricta, but neither of these has the tooth on the tenth

segment.

N.B.—The female from Ta-chien-lu referred doubtfully to

4. juncea in my former paper has no relationship to the

present species, and was probably correctly referred.

extending across. Colour of the body brighter green; a

Western China and Eastern Thibet. a1

small yellow spot or line on the sides of the thorax above

the insertion of each coxa, and a similar spot or line on

each coxa itself externally ; some small yellow spots under

the insertion of the wings. Ninth and tenth abdominal

segments slightly pulverulent ; a median yellowish line on

the dorsum of the ninth not reaching the extremities, and on

this segment slightly before its apex there is a small median,

nearly acute, conical tubercle, a slight median carina on the

tenth ; appendages shorter than the tenth segment, black,

slightly divergent; vulvar lamina of the ninth ventral

segment strong, broadly keel-shaped, its appendages black,

filiform.

Wings hyaline, pale fuliginous, slightly tinged with oliva-

ceous at the extreme base and along the costal margin to the

nodus; neuration mostly reddish, the marginal nervures

black, the costal nervure whitish pruinose externally ; the

nodal sector takes its origin slightly before the continuation of

the nodal vein (in the male in my possession this sector arises

distinctly after the nodal vein); pterostigma dull yellow

between strong black veins (length 4 millim., broader than in

the male) ; about 45 antenodal nervules in the anterior wings.

Length of abdomen 60 millim.; length of posterior wing

53 millim.

Considerably larger than the male, with no trace of the

red base of the wings so conspicuous in that sex. The colour

of the neuration and of the pterostigma resembles that seen in

the very immature male described by Kirby as A. basilactea.

Vestulis smaragdina, Selys.

One very adult female from Moupin. It differs somewhat

from the description and from specimens from the Khasia Hills

in my collection. The size is larger (abdomen 43 millim.,

posterior wing 40 millim.). ‘The abdomen above is metallic

blue rather than green, with the ninth and tenth segments

conspicuously whitish-pulverulent. The legs (excepting at

base) nearly blackish, with the femora brown internally.

Wings hyaline, with scarcely any trace of reddish tinge, but

slightly olivaceous at base and along costal margin; neura-

tion almost blackish, dark brown in certain lights. It is

probable that most of the differences above noticed (excepting

that of size) are due to the individual being highly mature.

These offer no peculiarities other than in abdominal sexual

characters. In less highly mature examples the terminal

segments of the abdomen are not pruinose above and the

wings are simply hyaline, with no olivaceous tinge. Possibly

the pterostigma is slightly shorter than in the male. The

point of insertion of the nodal sector is slightly variable in

different individuals, and there is sometimes only one nervule

in the quadrilateral of the hind wings (in one individual there

is only one such nervule in the right anterior and left poste-

rior wing and two in the other wings).

The discovery of the male renders it certain that this insect

is a Pyrrhosoma rather than an Erythromma (the two genera

being defined by scarcely more than colour differences). The

single example is from Siao-Lou, in the same district as the

locality whence came the females.

¢. Head and thorax as in the female, the pale lines on the

thorax more reddish. Abdomen much more slender, bright

red ; first and second segments yellowish at sides and beneath ;

a large black subquadrate mark on the first segment above,

and the posterior margin of this segment and also of the third

is narrowly black ; an isolated line on the sides of the seventh

not reaching the margins, a thicker and shorter line on the

eighth reaching the anterior margin only, and a quadrate spot

on the ninth (also reaching the anterior margin) all black; an

indication of a paler (yellowish ?) dorsal spot at the base of

the seventh, and the ninth and tenth also paler; margin of

the tenth shallowly excised in its middle. Appendages

reddish yellow, longer than the tenth segment; superior ap-

pendagessubcylindrical, inserted distantly, somewhat divergent,

broader at base, the apices somewhat suddenly incurved and

blackish ; inwardly at the base is a short slender branch or

tooth inserted at nearly a right angle; inferior appendages

broader and slightly shorter, their tips incurved and obtuse if

viewed laterally.

Wings tinged as in the female; pterostigma somewhat

more reddish; 4 antenodal cellules, 15-16 postnodal nervules

in the anterior wings.

Length of abdomen 27} millim.; length of posterior wing

21 millim.

This is the analogue of the European P. minium rather

than of P. tenellum. Both these species have a form of the

female in which the abdomen is nearly wholly black or

blackish ; and it seems quite possible that a form of that of

P. tinctipenne may be discovered in which the abdomen is in

part red.

LIV.—A Further Revision of the Species of Scorpions be-

longing to the South-African Genera Uroplectes, Lepreus,

and Tityolepreus*. By R. I. Pocock, of the British

Museum of Natural History.

THE distinctions between the genera Lepreus, Uroplectes, and

Tityolepreus, based upon the dentition of the digits of the

chele, depends, firstly, upon the number of enlarged teeth

(whether 0, 1, or 2) at the apex of the median rows; secondly,

upon the position taken up by the teeth of the internal row

with regard to the apices of the median series f.

Perhaps the simplest form of dentition is found in such

species of Lepreus as planimanus, Karsch, carinatus, Poc.,

and variegatus, C. Koch, where none of the apical teeth of

the median rows are enlarged and the teeth of the inner series

are throughout the dental area only separated by a small

space from the extremities of the median rows and form

transverse series with the two enlarged teeth, constituting the

posterior termination of the median rows. But the position

varies a little in the species named, the inner teeth being

further forward in planimanus and carinatus, so that the short

transverse rows are oblique, and a little further back in

varvegatus, the transverse rows being more angular. ‘To this

section belongs, in all probability, the type of the genus

Lepreus, L. pilosus, Thor., which is unfortunately unknown

to me in nature.

The second type of dental formula to be noticed occurs in

such species as vittatus and Pischert, which were also referred

to Lepreus; but the formula here is very different, the

teeth of the inner set being separated by a wider space from

the middle rows than in L. planimanus, and in the posterior

five sixths of the digit the individual teeth of the inner series

lie well behind the apex of the corresponding median row, so

that they alternate with the pair of enlarged teeth of the outer

set, instead of forming short oblique transverse rows with

them. Considerable difference, however, in the position taken

up by the inner teeth is observable, the teeth lying much

* Collectors and others in South Africa who are not acquainted with

the generic characters of Scorpions may usually readily recognize the

species belonging to this group by their small or medium size, tolerably

slender build, thin claws, and bright colouring, most of the species being

variegated with black and yellow spots or stripes, though sometimes the

body approaches a uniform bright green or even black. —

+ For the sake of clearness I am considering in this instance that the

teeth of the inner series have arisen independently from those forming

the median series.

Ann. & Mag. N. Hist. Ser. 6. Vol. xvii. 27

378 Mr. R. I. Pocock on South-African Scorpions.

further back in a Transvaal example of Z. vittatus than in

the Somaliland form L. Fischert. A variation of this for-

mula is seen in occidentalis, where the inner teeth occupy

almost the same position as in /scher?, but in the distal third

of the digit the apical tooth of the median series becomes a

little enlarged and slightly separated from the rest, and forms

with the adjacent tooth of the inner set a pair of teeth. It is

upon this character in this species that Kraepelin has based

his genus Tvtyolepreus.

A fourth arrangement is found in such species as chloro-

dermus and triangulifer, Thor., which are usually referred

to the genus Uroplectes. In these the disposition of the

teeth is only a little different from what is seen in occ?-

dentalis (chinchoxensis), the inner teeth at the proximal end

of the digit being isolated and removed to some distance from

the apices of the median rows, though in the distal two thirds

of the digit they approach the median series and are paired

with the slightly enlarged and separated apical teeth. The

disposition, however, in the two species named is not identical,

and in the closely allied species U. olivaceus, here described

as new, yet a third variation is presented, the internal teeth

being much closer to the ends of the median rows at the

roximal end of the digit than in the other two.

And, lastly, there is a fifth arrangement exhibited by such

species as lineatus, Koch, and formosus, Poc., in which the

inner teeth are close to the apices of the median rows, forming

with the two enlarged and separated terminal teeth of these

rows a recurved series.

Trusting to these data, it seems to me to be logical to

follow Kraepelin, refusing to recognize the three genera

Lepreus, Tityolepreus, and Uroplectes, as established, since

there are no fewer than five dental formule presented by the

known species of this section, and the formula varies in closely

allied species.

It seems, therefore, that if we adopt the system of splitting

the species into several genera according to dentition of the

digits, consistency will compel us to recognize no fewer than

five. I prefer, however, to adopt the alternative hypothesis of

referring all the species to a single genus Uroplectes, since, in

the first place, in addition to the considerations mentioned

above, we do not know the dental formula of U. ornatus, Pet.,

the type of the genus Uroplectes, whether it be like that of

lineatus or like that of triangulifer, and consequently cannot

say to which section of the species the name should be applied ;

nor do we know with exactness that of the species named

pilosus, Thor., ogimbinguensis, Karsch, lunulifer, Sim., and

Mr. R. I. Pocock on South-African Scorpions. 379

tricolor, Sim., for although all these forms were referred to

Lepreus, their dentition may be of the type presented by

planimanus, or by vittatus, or by occidentalis. And, lastly,

since all these forms inhabit a single geographical area, it is

in the highest degree probable that when the described forms

have been re-examined and others discovered still more inter-

mediate links than now exist will be found between the various

types of dental formula. Prof. Kraepelin has, however,

attempted to maintain the genera Lepreus and Uroplectes on

other grounds (Jahrb. Hamb, Anstalten, xii. p. 7, 1895),

referring to the former the two species pilosus and planimanus,

in which there are small lateral keels on the terga, a long

basal pectinal tooth in the female, and no tooth beneath the

aculeus on the poison-vesicle; and to the latter the species in

which there is only one crest on the terga, the basal pectinal

tooth is not elongate, and there is a tooth beneath the aculeus.

But as regards the armature of the vesicle, it may be said that

variegatus of Koch, which resembles pilosus and planimanus

in having the lateral tergal crests, has a large tooth on the

aculeus ; and concerning the structure of the basal pectinal

tooth in the female, it may be added that in the female of

U. triangulifer and of U. Marshalli this tooth is unmodified,

and that in variegatus it is also of the same form as in linea-

tus, and is not elongate as in pilosus and planimanus ; so that

this feature cannot at present be looked upon as of generic

importance. And, finally, I doubt if the genus Lepreus can

be maintained on the presence of the lateral tergal keels ; such

keels, at all events, are not accorded this importance in the

ease of Archisometrus tricarinatus and Buthus quinque-

striatus.

Lepreus carinatus, Pocock, Proc. Zool. Soc., March 1890, pp. 129, 130,

pl. xiv. fig. 3.

Prof. Kraepelin * has recently asserted that this species is

identical with planimanus, Karsch; but the examination of

examples of the latter species has shown me that the two, as

I originally supposed, are distinct. In carinatus the tail is

more strongly keeled, the median keel being quite strong on

the third segment and distinctly traceable on the fourth, and

the inferior keels on all the caudal segments and the vesicle

are distinctly granular. In planimanus the inferior keels are

smooth on at least the first and second caudal segments,

weakly granular on the rest, vesicle punctured basally,

the median lateral crest absent on the fourth caudal and

exceedingly short on the third; and, lastly, in plantmanus,

as the name indicates, the hand, especially in the male, is flat

above, broad, and with its inner edge compressed, whereas in

carinatus it is thinner and of the normal spherical form. ‘The

small disparity in size between the type of carinatus and the

smallest male of planimanus lends no support to the suppo-

sition that these distinctions are due to differences of age.

Unfortunately we have no nearer locality for this species

than 8. Africa, near the Tropic of Capricorn. It agrees with

my examples of planimanus in having nine distinct median

rows of teeth on the digits, without counting the exceedingly

short apical set. According to Karsch there are only eight

rows of these teeth.

Uroplectes variegatus (C. Koch).

Tityus variegatus, C. Koch, Die Arachniden, xi. p. 9, fig. 855 (1845).

Colour pale yellow, variegated with black; the interocular

area black, mesially flavous in front, the area of the carapace

behind the tubercle with a black edge, irregularly fuscous

laterally and fuscous in the middle. The tergites adorned

with seven black lines, the three keels on each and the lateral

edges being black, with a large black patch between the edge

and the lateral keel; the tail black-lined, the pigment

marking the keels; there is also a black line in the middle of

the dorsal surface and one in front in the middle of the infe-

rior surface; the fifth segment fuscous throughout, only

obscurely fulvo-lineate ; vesicle entirely pale, aculeus poste-

riorly black. Cheliceree entirely pale. Chelee with trochanter,

humerus, brachium, and manus variegated with black, the

last two especially so posteriorly, digits pale. Legs with

femora and patella variegated with fuscous ; lower surface of

the trunk quite pale, the last sternite only being obscurely

lined with black.

Carapace coarsely granular but not carinate, the ocular

tubercle granular. erga coarsely granular, each of the

first six marked with three granular keels, the lateral keels on

the anterior segments only represented by a single tubercle,

the keels on the seventh tergite strong and denticulate.

Three anterior sternites smooth but punctured, the fourth

slightly granular in the middle, more thickly at the sides, the

fifth closely granular throughout, the normal keels only

marked by a few larger granules.

Tail slender, a little narrowed posteriorly, about 44 times

the length of the carapace; its intercarinal spaces finely

granular ; the keels well developed and granular or denticu-

late, the first three segments with 10 keels, with a trace of

the median lateral on the fourth; the superior keels denticu-

late, the terminal denticle being larger; the superior borders

of the fifth not carinate, the inferior strongly denticulate; the

vesicle granular, with a distinct triangular tooth beneath the

aculeus, the whole tail beset with strong sete,

Palpt granular, humerus carinate, brachium not carinate,

manus not carinate and not granular, hairy, rounded, about as

wide as the brachium; the digits in contact, the movable

about twice the length of the hand-back and furnished with

8 rows of teeth along the middle line; the basal row long ;

teeth of the inner series a little behind the apices of the corre-

sponding median rows.

Legs granular ; the feet not thickly hairy beneath.

Pectines short, furnished with 15 teeth, of which the basal

is enormously enlarged but not elongate.

Total length 28 miilim., of tail 16°5, of carapace 2°8.

Loc. Cape Town (H. A. Spencer and G. H. R. Fisk) and

Simon’s Town (De la Garde).

A single female example taken by each of the above

collectors.

This species resembles pelosus, Thorell, planimanus, Karsch,

lunulifer, Simon, and carinatus, Pocock, in possessing three

keels upon the tergites; in these other species, however, the

pectinal teeth are over 20 in number, varying from 23 to 31,

and there is no tooth beneath the vesicle on the tail.

I have published a full description of this species, because,

so far as I am aware, no examples of it have been examined or

described since 1845, when C. Koch first established it ; and

382 Mr. R. I. Pocock on South-African Scorpions.

it was under the guidance of this description that Prof. Krae-

pelin was led to locate the species in close proximity with

U. lineatus. Its true position amongst the South-African

species may be seen by referring to the synoptical table.

Uroplectes lineatus (C. Koch).

Tityus lineatus, C. Koch, Die Arachniden, xi. p. 7, fig. 854 (1845) ;

Kraepelin, Jahrb. Hamb. Wissen. Anst. viii. p. 89 (1891).

During recent years the British Museum has received a

large number of specimens of this species from Cape Town

and from Wynberg, Hoet’s Bay, and Kalk Bay in the neigh-

bourhood (//, A. Spencer), also one from Simon’s Town

(De la Garde), making a total of 17 specimens of different

sizes and sexes. ‘The males differ from the females in having

the tail longer, the hand thicker, and the basal pectinal tooth

not enlarged.

The colour is very fairly constant, that of the upperside

of the trunk consisting, roughly speaking, of three yellow

bands alternating with four black ones; but the yellow bands

are not continuous, the median one being broken up by a

pigment patch on the keel and the lateral ones being in reality

extensions of the > <-shaped markings so characteristic of

many species of this genus. The tail is banded with black,

the bands mostly marking the keels, but at the sides, especially

of the posterior segments, they show a tendency to broaden

and fuse; the lower side of the first three segments is pale,

with a fine median black line; the vesicle is always yellow.

Uroplectes insignis, Poe.

Uroplectes insignis, Poc. Proc. Zool. Soc. 1890, p. 131, pl. xiii. fig. 4.

This species was based upon a couple of examples obtained

by Dr. Dobson on Table Mountain, and at the time, owing to

scarcity of material of this form and of U. lineatus, I was

unable to compare the two in any detail. But, thanks to the

acquisition of a large number of examples from Table Moun-

tain (H. A. Spencer), I am now able to point out that it

resembles U. lineatus in almost all structural characters,

although differing considerably and, apparently, constantly in

being far more strongly pigmented. For instance, the banding

of the trunk observable in lineatus does not appear here, the

two lateral yellow bands of the former being reduced to the

> <-shaped markings ; the vesicle, moreover, is black below

and at the sides, with four fine yellow lines, and the median

black stripe on the lower surface of the tail is broad and

Mr. R. I. Pocock on South-African Scorpions. 383

divided by a fine yellow line. The only other distinctive

feature that I notice in this form is the smaller size of the

tubercle beneath the aculeus.

From the constancy of these characters it seems to me that

U. lineatus must at all events be looked upon as a distinct

subspecies, a melanistic mountain form, of U. lineatus. It is

a significant and interesting fact that Mr. H. A. Spencer,

who, while acting as medical officer on board the U.S.S. ‘ Mexi«

can,’ was collecting on and off for some years in 8. Africa,

never took the typical U. lineatus upon Table Mountain nor

U. insignis on the lower ground in the neighbourhood of

Cape Town, and he himself was struck by the darker tint of

the mountain form.

Principal form.— With a single small fuscous spot upon the

upper surface of the trochanter of the palp; two spots upon

the femur, one at its distal and the other at its proximal end ;

two spots upon the tibia, one small, distal, the other larger

but irregularly defined and median; the hand blacker; a

fuscous spot upon the maxillary lobes of the first and second

pairs of legs. The >-shaped spot very indistinctly defined ;

the last tergite almost entirely black at the sides, with only a

very narrow yellow stripe just above the black margin; the

lower surface of this last segment also almost entirely fuscous,

with a posterior median triangular yellow spot. ‘The upper

surface of the first four tail-segments entirely orange-red, not

black ; the lower surface of these segments with a thin inferior

median black band and adorned with irregular black patches

at the side. ‘The vesicle of the tail with scarcely a trace of

yellow lines.

Loc. Port Natal (Z. Howlett).

Uroplectes formosus, Poc., subsp. Spencer?, nov.

Coxe and maxillary lobes of the anterior appendages

the proximal end of the humerus above ; the proximal patch

upon the brachium larger and better defined ; the hand paler

and distinctly black-lined. ‘The flavous >-shaped mark on

the tergites well defined, the seventh tergite largely flavous at

the sides; the sternite flavous, with three black bands, one

slender median and one on each side wider and less well

well-defined black longitudinal lines, one inferior and median

and three on each side, the upper marking the superior keels ;

the vesicle distinctly yellow-lined.

Loc. East London (fH. A. Spencer).

In addition to the large number of examples obtained at

the above locality Mr. Spencer brought back others from Port

Elizabeth which, while agreeing in the main with the typical

East London examples, differ from them in being rather more

deeply pigmented. For example, the ><-shaped marks on

the terga are less distinct, almost the entire upper surface of

the brachium and humerus is fuscous, and the black lines on

the tail are wider, so that sometimes they anastomose.

On pl. xiii. fig. 5 of my paper (Proc. Zool. Soc. 1890) upon

South-African Buthide I give a figure of the male of this

species taken from an example collected at Pietersberg

(Transvaal) by Mr. C. R. Jones, this being the only example

contained at that time in the Museum collection ; but since

then we have received fresh examples from Port Elizabeth

(H. A. Spencer) and Basutoland (. C. Wroughton).

The differential characters of this form and its allies are

pointed out in the synopsis of the species.

rate ; not U. flavoviridis, Peters, Mon. Ak. Wiss. Berlin, 1862,

p. 616.

This species, of which I have given a full description of

both sexes in the Proc. Zool. Soc. for 1890, I formerly re-

garded as identical with U. flavoviridis of Peters, from Tette ;

but I am now of opinion that the two must be regarded as

distinct, on the grounds that Peters describes the underside of

the tail of his species as shining and finely granular, whereas

in my specimens its first three segments are quite smooth

and studded with coarse punctures, which can scarcely have

been overlooked by Peters and, still less, described by him as

fine granules. Moreover, this author states that the basal

pectinal tooth is of striking size and falciform (“ sichelférmig’”’)

in shape, from which I infer that he had before him a scorpion

with the sickle-shaped basal pectinal tooth of U. planimanus

or U, lunulifer, and not an example with this tooth merely

expanded, as is the case in U. chlorodermus,

Mr. R. I. Pocock on South-African Scorpions, 385

In addition to the examples of this species from KE. Africa

and Lake Nyassa that I have previously recorded, the Mu-

seum has received it from Fort Salisbury, Mashunaland,

5000 feet (G. A. K. Marshall*). U. chlorodermus resembles

triangulifer in many characters—for instance, in the thin spine-

armed hand of the male, approximately in the arrangement

of the teeth on the digits of the chele ; it may, however, be

recognized by being of a uniformly deep green colour, and

having the anterior caudal segments smooth, punctured, and

not carinate below, the basal pectinal tooth expanded in the

female, and the sides of the upper surface of the fifth caudal

segment straight and abruptly sloped posteriorly. In the

three last-named respects it approaches the Somaliland and

East-African U. Fischert, Karsch.

Uroplectes olivaceus, sp. n.

Colour somewhat the same as in U, flavoviridis, Peters, but

the green paler, more emerald on the upper surface of the

trunk and chele, yellower on the tail; fingers and trochanter

of chele yellow; legs yellow and green, a broad band of the

latter colour occupying the whole of the middle of the femur

and patella; lower surface of trunk yellow or greenish

yellow.

Carapace as long as the second caudal segment, finely and

closely granular throughout ; ocular tubercle smooth. Terga

also finely granular, more coarsely so posteriorly, the pais

keel smooth, but the keels on the last granular.

Sterna smooth and polished, the last very weakly granular

at the sides.

Tail about 64 times the length of the carapace, robust,

parallel-sided ; the inferior median keels weak, obsolete on

segments 4 and 5; a weak median lateral keel on segments

1 to 8; all the keels and the intercarinal spaces granular

except the median area on the lower surface of the first

segment and the upper surface of all the segments, which are

at most feebly granular; the upper keels of segments 1 to 3

ending in an enlarged denticle; upper edges of the fifth

segment high and strongly convex; the hinder half of the

upper surface very deeply impressed for the reception of the

distance below the root of the aculeus, its upper surface

depressed at the base, strongly convex on its distal half, the

curvature of which is continuous with that of the vesicle.

Chela long and slender; humerus and brachium finely and

closely granular above, more coarsely granular in front;

manus slender, about as wide as the brachium, smooth, but

punctured and hairy; a distinct tubercle on its inner surface

at the base of the digits; width of hand a little more than

half the length of the hand-back ; hand-back less than half

the length of the movable digit ; digits long, rather strongly

curved at the end; 11 rows of teeth along the median

series, the basal row long, with an enlarged denticle on each

side of it near the middle of its length ; the teeth of the inner

series lying close up to and a little behind the apical tooth of

the median rows, which is scarcely larger than the rest and

not separated from them by a larger space than that which

separates the rest of the teeth of the median rows from each

other.

Legs weakly granular externally.

Pectines long, with 23-24 teeth.

Measurements in millimetres.—Total length 60; length of

back 3, of movable digit 6°5.

Loe. Murchison Range, Transvaal (C. f. Jones).

Belonging to the same category as U. chlorodermus and

U. triangulifer, but recognizable from both in the characters

pointed out in the synopsis.

Ureplectes vittatus (Thor.).

Lepreus vittatus, Thorell, Act. Soe. Ital. Sci. Nat. xix, p. 121.

A single female example of this species recently received

from the Murchison Range, Transvaal (C. &. Jones), presents

the following type of coloration :—

Carapace ornamented in front with a triangular black patch

lying between the eyes; the posterior apex of this patch ex-

tends beyond the ocular tubercle halfway towards the posterior

margin, the posterior edge with two transverse black lines

and the lateral edge black nearly up to the lateral eyes. The

anterior four terga with black or partly black edges, all of

them except the last, which is almost of a uniform yellow,

furnished with two large conspicuous black spots, which con-

stitute together a double dorsal band, but each of these black

spots is distinctly divided by a >-shaped yellow mark ; the

yellow bands which lie between the black bands are subequal

in width and much more brightly coloured posteriorly. Tai7

yellow, passing into a redder tint posteriqrly ; the lower

surface of the first segment is furnished behind with two

abbreviated black lines, that of the third has the corresponding

lines better developed and a slender median line which takes

its origin from a conspicuous black spot on the anterior

portion of the segment; ornamentation of the same kind is

noticeable upon the lower surface of the two following seg-

ments, but it is less clearly defined on the fourth.

Legs and palpi yellow ; digits infuscate.

Thorell’s type from Caffraria was doubtless a male, since

no reference is made to the enlargement of the basal pectinal

tooth observable in my example, in which there are 18-19

teeth, the basal being modified as in U. occ¢dentalis and

lineatus, and not elongate as in U. planimanus and lunulifer.

This specimen also differs in two other respects from Thorell’s

description, since it possesses twelve rows of teeth along the

middle line of the digits, instead of eleven as stated by

Thorell, and the movable digit is nearly twice the length of

the hand-back (52:3), whereas in the type of vittatus the

difference is much less, being only 54:4. But without more

specimens for examination it 1s not possible to say whether a

specific or subspecific value is to be attached to these features.

Uroplectes Fischeri, Karsch.

Uroplectes Fischert, Karsch, Mitth. Minch. ent. Ver. 1879, p. 124.

Recorded from Barawa in Somaliland; the British Museum

has recently received examples of apparently the same species

from Mombasa (D. J. Wilson) and Kast Africa (Imperial

British East Africa Company). According to Kraepelin this

species is identical with the foregoing U. vittatus, but the

three above-mentioned examples referred to fischeri may be

distinguished from the Transvaal example of vittatus in the

features pointed out in the diagnosis. Kraepelin’s description

is apparently based upon specimens from unstated localities,

one only being mentioned as coming from Somaliland, and

this is probably identical with Fscher’. According to this

author the variation in colour presented by the “ species ”’ is

very great, specimens even having the segments of the legs

ringed with black. The examples seen by me agree with

Karsch’s description, except that they seem to approach my

example of U.vittatus more nearly in colour and have the hands

pale, whereas in the type of Fischert these organs are said to

be marked with longitudinal blackish lines. The specimen

that I described as nigri’manus seems to represent a melanistic

388 Mr. R. I. Pocock on South-African Scorpions.

form of the same species and may provisionally, at all events,

rank as a subspecies.

Uroplectes occidentalis, Simon, Bull. Soc. Zool. France, 1876, p. 219.

Tityus chinchoxensis, Karsch, Zeits. Naturw, lii. p. 870 (1879).

The British Museum has examples of this species from the

Congo (whence the type was obtained), Angola, and Cette

Cama (Gaboon) ; but, according to Kraepelin, it spreads as

far to the north as Sierra Leone and eastwards and southwards

into Somaliland, Masailand, and Natal. If these localities

are trustworthy, the species has a wider range in Africa than

any indigenous scorpion with which I am acquainted.

Furthermore, this author also affirms that he has examined

specimens from Sumatra, Java, Borneo, and Celebes.

As stated above, this species, of which I have published a

coloured figure in the Proc. Zool. Soc. 1890, pl. xiv. fig. 4,

is the type of Kraepelin’s genus Tvtyolepreus; but I feel

satisfied of the impossibility of separating it generically from

such forms as vittatus and Fischert.

The sections indicated in this table by the numbers 1, 2, 3, 4

represent, I believe, the natural groups into which the species

fall; but at present, for reasons stated above, I do not con-

sider it advisable to adopt generic titles for these sections.

Probably, however, the name Lepreus applies to no. 1 and

Tityolepreus to no. 2; but it appears to me by no means

certain whether Uroplectes, the oldest name for the group, is

applicable to 2, 3, or 4.

The following species, unknown to me in nature, also fall

into this genus :—

1. Scorpio (Atreus) spinicaudus, Gervais (Arch. Mus. iv.

p. 222, pl. x1. figs. 22-25, 1844), from Caffraria, will probably

be found to belong to no. 4, and will perhaps prove identical

with UW. formosus Spencer.

2. Tityus fallax, C. Koch (‘ Die Arachniden,’ xi. p. 1,

fig. 850), from Africa, also apparently falls under no. 4. If

adult, the type probably represents a species distinct from

those enumerated, but if immature may prove to be the

young of U, insignis.

3. Tityus striatus, C. Koch (t. c. p. 6, fig. 853), from

Africa.—The same remarks apply to this form as to 7. fallax.

On the strength of the figures of these species it is impossible

to say for certain that they are synonymous with any of those

recognized in the above table ; for it is unjustifiable to ascribe

inaccuracy to these figures, seeing how accurate on the whole

are those of U. lineatus and U. variegatus.

4, Uroplectes ornatus, Peters (Mon. Ak. Wiss. Berlin,

1862, p. 516), from ‘I'ette, was said by Karsch to fall into

“Tityus” of C. Koch, a statement which means presumably

that it belongs to the same category of species as U. triangu-

lifer, Thor. It isa pity that we cannot locate this species

more satisfactorily, for since it is the type of the genus Uro-

plectes, its exact systematic position is of the greatest import-

ance to those who would more finely divide the genus.

5. Uroplectes flavoviridis, Peters (Mon. Ak. Wiss. Berlin,

1861, p. 516), from Tette-—The position of this species is

also one of perplexity. The only other species, so far as I

know, that have been accredited with a falciform basal pectinal

tooth are U. planimanus and U. lunulifer ; but these certainly

differ from flavoviridis in having the lower side of the tail

distinctly carinate.

6. Lepreus pilosus, Thorell (Act. Soc. Ital. xix. p. 118,

1876), from Caffraria, the type of the genus Lepreus, without

much doubt falls in section 1 of the table, but certainly differs

from the forms enumerated there in having the median infe-

rior keels obsolete on the first, second, third, and fourth

segments of the tail.

7. Lepreus otjimbinguensis, Karsch (Mittl. Miinch. ent.

Ver. 1879, p. 125), from Otjimbingue, near Walfisch Bay.—

Judging from the description I should say that this species

belongs to section 2 of the table ; but it certainly differs from

the species there mentioned in having the median part of the

terga black and not yellow.

8. Lepreus lunulifer, Simon (Ann. Soc. Ent. Fr. 1887,

p- 875), from Namaqua or Damaraland, is evidently very

nearly allied to Z. planimanus, Karsch. Kraepelin, indeed,

holds the two to be identical. At all events, it is not possible

without a comparison of the types to express the differential

characters from the description alone.

9. Tityus tricolor, Simon (Bull. Soc. Ent. Belg. xxvi.

p. lix, 1882), from the area lying between Zanzibar and the

lake region, almost certainly falls into section 2. From the

fact that Simon refers it to Z%tyus I am inclined to think the

dentition of the digits will be found to resemble that of occi-

dentalis, Sim., to which, as well as to vittatus and Fischeri,

the species is evidently nearly allied.

SUPPLEMENT.

Whilst this paper has been in the printer’s hands I have

received from Mr. G. A. K. Marshall a couple of species of

this genus from Durban. One of these proves to be U. plani-

manus of Karsch, identical in almost all respects with the

Mashunaland example mentioned above ; but the other appears

to be an undescribed form, which I propose to dedicate to its

discoverer and diagnose briefly in the following terms :—

table, but easily recognizable from this species in the following

features :—

Colour of trunk and tail a deep and uniform black, the

appendages deep green; the three basal segments of the

chele paler green than the brachium and manus; fingers

yellowish green; femora and patella of the legs also deeper

than the rest, the adjacent ends of these segments, as well as

the opposite end of the patella, conspicuously red; the max-

illary lobes of the first and second legs deeper green than the

rest of the coxx.

Granulation of the trunk and tail and keels on the latter

developed as in triangulifer ; area of the vesicle below the

aculeus prominent, but ouly furnished with a tubercle, which

is considerably smaller than that of triangulifer.

Pectinal teeth 18-18, 20-21 in ?, 18-20 in @; the teeth

longer in the latter, but the basal tooth not enlarged in the

former.

Vesicle of male modified as in U. triangulifer, and, as in

that species and in chlorodermus, the spike on the hand is

larger in this sex than in the female.

A male and two females with many young were taken. It

is interesting to note that the young specimens, 8 millim, in

length, present the colouring ot the adults with the exception

of being a little paler.

Note.—In two papers upon African Scorpions recently

published (in the March and April issues of the ‘ Annals’) [

have recorded certain species from the Umfuli River,

Mashunaland ; but, owing to the partial obliteration of the

label, the altitude was given as 1200 feet. It is, in reality,

as Mr. Marshall intorms me, 4200 feet, the exact spot being

known as Gadzima.

LVI.—Description of a new Nymphaline Butterfly from

Burma. By Lionev DE Nicévit1e, F.K.S., C.M.Z.8., &e.

Mr. H. J. Exwes has kindly sent me a specimen of a species

of the Nymphaline genus Newrosigma from the Karennti

country, lying to the north-east of the Burmese province of

Pegu, which, as it undoubtedly represents a new species

distinct from Neurosigma Doubledati, Westwood, the hitherto

unique species in the genus, I describe as follows :—

Neurosigma nonius, sp. n.

Hab. Karenni, Burma.

Expanse, $ 32 inches.

Description.—Male. Upperside: fore wing differs from the

same sex of N. Doubledait, Westwood, from Nepal, Sikkim,

Assam, and Upper Burma, in having the fulvous coloration

of the ground confined to the basal third of the wing, the

ground-colour of the rest of the wing being creamy white.

Hind wing has the ground-colour everywhere creamy white,

in N. Doubledait the discal area of the wing occupying half

the surface is fulvous. Underside: both wings present the

same differences as on the upperside, in addition to which all

the black markings are of a deeper and richer shade and larger.

Female unknown.

Mr. W. Doherty, who captured numerous male specimens

of this species in March and April, 1890, recognized it as a

new species, as he wrote to Mr. Elwes:—‘ 1 send many

males of Neurosigma Doubledayi. It seems to me distinet

from the Sikkim form, of which I took dozens in the Chitta-

gong hill-tracts, all black and fulvous above.” Mr, Elwes,

however, in Proc, Zool. Soc. Lond. 1891, p. 277, did not

describe it as new, but refers to it as Newrosigma Doubledayt,

var.?, and figured it on pl. xxvii. fig. 7, as he thought it

might be “ a case of male dimorphism in which the male and

female are different in some localities and resemble each other

in others.” As, however, both sexes of N. Doubledaii are

known and have been figured, and both are represented in my

collection, I do not think that Mr. Elwes’s suggestion is

likely to prove correct, although we know only one sex of

the Karenni local race. It will be most probably found, when

the temale of N. nondus is discovered, that it closely resembles

its male and has no fulvous coloration whatever on the hind

wing, while the female of N. Doubledait has a small patch of

that colour in the middle of that wing on both surfaces.

398 M. C. Janet on the Relations of the

LVIII.—On the Relations of the Myrmecophile Lepismide to

Ants. By M. Cuaries JANet *.

THE numerous species of animals which live in ant-hills, and

which for this reason have been called “ Myrmecophile,” have

very varied relations with the ants fT.

A certain number of Staphylinide, such as Myrmedonia

funesta, which have been especially studied by Wasmann,

capture the ants at the entrance to their galleries or the larve

in the deeper parts of the nest and devour them (myrmeco-

phagy).

Certain Nematodes plant themselves in the pharyngeal

glands of the Camponotide, in order there to pass through a

larval stage (¢nternal parasitism) (‘Comptes Rendus,’ t. exvil.

p- 700, 1893).

Certain Acarids attach themselves to different parts of the

bodies of the ants, and especially to the head and feet (eaternal

parasitism).

A considerable number of Arthropods enter the ants’ nest

for hardly any other purpose than to seek the detritus, of

which they are able to make some use, or to find there favour-

able conditions for their existence, and they are treated with

indifference by their hosts. This is the case with a little

Isopod Crustacean, Platyarthrus Hoffmanseggt, which is so

common in ant-hills all over Europe. ‘This cohabitation in

the same nest of a myrmecophile species with ants has been

called synewketism when there is no direct relation between

them.

Many of the Staphyltinide and Pselaphide live normally

in ants’ nests. ‘They bear on the dorsal region tufts of hair,

corresponding with certain glands the secretion of which is

much sought after by the ants, who, in exchange for it, pour

out for them voluntarily before their mouths a liquid tood.

There is in this case between the ants and their guests

a symbiosis with reciprocal advantages, constituting the

myrmecoreny of Emery. Wasmann has shown that among

the myrmecophile Staphylinide the reduction, more or less

pronounced, of the palps was, so to speak, the expression of

the degree of dependence of these insects upon the ants who

housed them.

* From the ‘Comptes Rendus,’ tome exxii. 1896, pp. 799-802.

+ A classified list of myrmecophile animals will be found in a recent

book, exceedingly useful to naturalists engaged in the study of ants, Was-

mann, Erich, ‘ Kritisches Verzeichniss der myrmekophilen und termito-

philen Arthropoden’ (Berlin, 1894).

Myrmecophile Lepismide to Ants. 399

This dependence is pushed to the last degree in the case of

Claviger testaceus, which is to be found often enough on the

ant-hills near Paris. Although in artificial nests one can see

these Coleoptera attach themselves from time to time to the

dead larvee, which they appear to suck for a moment, it may

be said that their true food is only that provided for them by

their hosts, because they die rapidly when they are separated

from them.

As for the Aphides, they are not truly myrmecophile : it

is true that they are greatly sought after by ants, who obtain

from them an abundant supply of food, and who, in exchang ge,

can extend to them a more or less real protection ; ; but they

neither ask nor obtain from the ants anything, and even in

general do without them.

The Lepismide have for a lone time been classed as

myrmecophile, but their relations to ants have up to the

present been but imperfectly understood. [ have had occa-

sion to notice in my artificial nests specimens of Lepismina

polypoda, Grassi, taken with a colony of Lastus umbratus,

Nyl., genus marina, Nyl.

In the first nest I placed some Lepismina without ants, in

a second Lepismina with the ants with which they had been

taken.

The Lepismina which had been brought up without ants

received as food a mixture of honey, sugar, flour, and yolk of

egg. They numbered at the beginning of the observations

twenty-one ; at the expiration of. two years and six months

there were still nine of them remaining in good condition, and

these readily ate the liquid honey which was given to them on

the point of a pair of very fine forceps.

The Lepismina brought up with the ants with which they

had been captured were much more lively than those from the

other nest. ‘They were in a state of constant movement, and

ran about among the ants, but took great care never to remain

stationary in their neighbourhood.

Occasionally I saw the ants threaten the Lepismina, and

even throw themselves upon them; but in the latter case

they were so agile that they invariably escaped. Never-

theless, in my artificial nest, in which they could not so easily

reach a place of safety as in a natural nest, they were sooner

or later caught. T'wo days after setting up the nest I found

five dead bodies, which the ants seized in their mandibles and

carried about the nest. In order to save the survivors I

began their training in a new nest, only certain portions of

which were accessible to the ants, or, at least, but little fre-

quented by them. There the Leptsmina remained for a long

400 Relations of the Myrmecophile Lepismide to Ants.

time in a state of repose, completely motionless ; but when an

individual ant passed near to one of them it never failed to

make a sharp movement in order to push it out of the way.

If the food smeared with honey, which was placed in the

empty chamber of the nest, was withheld for several days and

then replaced, a number of ants would be seen to come and

make a lengthy meal on it, and when, after filling themselves

as full as they could hold, they went back to the hving

chambers of the nest, they were assailed by their companions,

who came to ask, with their antenne, a share of the food.

The division began immediately. The one with the food

and the one requiring it arranged themselves one slightly in

advance of the other; the former drew aside its mandibles

and protruded its proboscis, which its companion seized with

its maxilla, and disgorged some small drops, which were

immediately absorbed.

From the moment that the first food-bearers entered the

living chambers of the nest the Lepismina showed by their

agitation that they had perceived the odour of honey.

Soon quite a number of ants were gathered in pairs for the

business of disgorging. The bodies slightly drawn back,

and often with the anterior feet raised, they left a certain

interval between them below their heads. As soon as a

Lepismina arrived near such a pair it would throw itself into

this space, raise its head sharply, snap up the droplet which

fell before it, and then get away as quickly as possible, as if

to escape a pursuit which was deserved. But the ants,

propped up one against the other, are not sufficiently free to

move, and cannot even threaten the audacious thiet, who runs

off at once to put another pair under contribution; and this

manceuvre is continued until hunger is satisfied.

One must conclude from these observations that Lepismina

polypoda can do without the ants well enough when there is

proper food at their disposal; that they are tolerated in the

ants’ nest for the simple reason that their agility saves them

from pursuit by the ants; that they are attracted to the ants’

nest by the bait of the nutritious liquid which the ants store

in their crops; and that, contrary to what takes place in the

case of myrmecoxeny, the ants do not give this liquid of their

own tree will to the Lepismina, but that these latter know

how to take advantage of circumstances to possess themselves

of it by stealth (myrmecoclepty).

A single specimen from Mount Lomis, Caucasus, 7000 feet,

received from the Tiflis Museum.

This Batrachian is of particular interest as adding a second

species to the genus Pelodytes, the range of which was believed

to be confined to France, the Spanish peninsula, and North-

west Italy. Not long ago but three species of Pelobatoids

were known from the Palearctic Region. The number is

now raised to five, viz. :—

1. Pelobates fuscus, Laur. (Central Europe and North-

ern Italy.)

2. Pelobates cultripes, Cuv. (France, Spain, Portugal.)

3. LPelobates syriacus, Bttgr. (Asia Minor, Syria.)

BIBLIOGRAPHICAL NOTICE.

On supposed Remains of Organisms from the Pre-Cambrian Strata of

Brittany. By Hermann Ravrr, of Bonn. With illustrative

cuts.

Ueber angebliche Organismenreste u. s.w. From the ‘Neues Jahr-

buch fiir Mineralogie,’ &¢., 1896, Bd. i.

Tue Author reviews the results arrived at by M. Cayeux in his

microscopic researches in these old rocks. After examining speci-

mens himself, Herr Rauff thinks that the so-called Sponge-spicules

are inorganic—merely microscopic threads and granules of some

decomposed metallic mineral, most likely pyrites.

He notices the extremely minute size and relatively enormous

number of the so-called Radiolarians. He observes that M. Cayeux

regards the matrix as having been crystallized from an original

state of Radiolarian earth; and Rauff asks if any one could deter-

mine optically the isotropic nature of the delicate and thin shells

and skeletous in the anisotropic enveloping material. He also asks

why M. Cayeux holds it possible that the Radiolarian skeletons, in

spite of the crystallizing of the quartzose medium in which they lie,

could keep their original colloidal silica, whilst for his Sponge-

spicules he does not allow of its possible preservation. Rauff con-

cludes that these so-called Radiolarians and Sponge-spicules are

minute spherical granules of some modified metallic mineral, probably

pyrites, in touch or coalescence one with another. Independent

corroboration of his views he finds in Dr. Hinde’s remarks on some

similar minute bodies in the ‘Quarterly Journal of the Geological

Society,’ vol. li. p. 631.

MISCELLANEOUS.

Modifications produced in the Organs of Sense and of Nutrition in

certain Arthropods by coufinement in Caves*. By M. Armanp Virg.

Nowurre does the influence of environment show itself more

markedly or in a more striking manner than in caverns: the

absence of light and the scarcity of prey produce in animals which

are drawn into them, and succeed in acclimatizing themselves

therein, modifications of various kinds.

The eye, always atrophied, is more or less so according to

the species and the individuals of the same species. In certain

Amphipod Crustaceans (Gammarus, nov. species) it presents varying

intermediate states between the almost normal eye, of a blood-red

colour and apparently still capable of perceiving certain luminous

sensations, and the completely depigmented eye, in which nothing

is preserved beyond the evterna/ primitive form. Some individuals

exhibit varying degrees of atrophy in one eye and the other.

* Researches made in the Jura in 1894-95 and in the physiological

laboratory of the Sorbonne.

408 Miscellaneous.

Among the Thysanura (Campodez and Poduride) the evolution is

more accentuated, inasmuch as the Poduride have still at the base

of the antenne some globules of a reddish colour, whilst the

Campodex have no trace whatever of a visual organ.

Certain sense-organs supply the place of the eye. Thus the

antennee of the Campodes, which in certain individuals are still

almost normal, reach in others a length more than double (the

normal) and become longer than the body. The same takes place

with the anal fork. The tactile hairs which cover the body take on

an exaggerated development, and appear in the Crustacea to go so

far as sometimes to invade the eyeball.

The sense of hearing, on the other hand, does not appear to be

proportionately increased, and a great noise may be made near a

subterranean lake without startling the animals (in it).

The sense of smell seems to be very acute, and putrid food left in

the water or on the ground is in a few minutes attacked by a large

number of creatures.

The digestive organs are considerabiy modified, as the result of a

mode of life which sometimes extends to the complete absence of

animal food in species normally carnivorous. Thus two (specimens

of) Staphylius caught in June last in the grotto of Baume-les-

Messieurs (Jura) had their mandibles atrophied,

The digestive tube of the Crustacea is found to be almost always

full of clay from the bottom of the lakes, which contains nothing

beyond the mineral matter except great quantities of microphytes

(algze, moulds, spores, &c.). Under the influence of this regime,

the digestive tube appears to have enlarged, sometimes it presents

knots and a certain tendency to twisting.

All the animals are depigmented more or less completely. Some

specimens still possess, however, a slight rosy coloration or minute

irregular patches of black pigment in contrast with the colourless

ground of the tissues. With regard to this point, it appeared to me to

be of interest to replace certain individuals in the light and observe

what would happen. The experiment, interrupted by accident at

the end of about a month, was nevertheless even then conclusive ;

the individuals were carefully taken from amongst the most etio-

lated, as exhibiting no trace whatever of pigmentation. In this

short space of time, one could watch the appearance of quantities

of small black specks, scattered over the whole body, and especially

abundant on organs accidentally amputated and in course of repair,

such as the antenne and feet. It appears, then, that this pheno-

menon occurs fairly rapidly. Later observations on «this head will

be reported.

The animals found may be classed as follows :—6 species of Crus-

tacea (Amphipoda and Isopoda), 2 species of Thysanura, 1 Acarid,

2 Arachnids, 1 Gasteropod, &e. They were taken principally

from the grottocs of Sainte-Catherine, at Consolation, Commune

of Maisonnettes (Doubs), Baume-les-Messieurs (Jura), Les Planches,

near Arbois, and Les Nans, near Nozeroy.— Comptes Hendus,

LX.—On some Odonata of the Subfamily Aischnina.

By Ropert M‘Lacuuan, F.R.S. &e.

THE new species here noticed form a portion of the

undescribed material | possess in the subfamily. The

sequence adopted is that of Dr. Karsch (1891), which in

several respects seems an improvement on that of Baron de

Selys (1883), especially in the discovery of important neural

characters. But I am of opinion that the formation of the

tenth ventral segment in the female will prove of more

importance than the later system allows to it, more especially

as the condition seen in Gynacantha is repeated in a North-

Indian genus (not here characterized) allied to Cephaleschna*

and Callieschna by neuration.

In the descriptions that follow I have adopted the minute

details of neural characters used by Dr. Karsch. It is

probable that eventually a plan of grouping species will

obviate the necessity for such exactitude. A certain amount

of latitude must be accorded to the interpretation of these

details, for at present they are often drawn up from very

limited material.

410 Mr. R. M‘Lachlan on some Odonata

with blackish hairs, with a black T-spot, the top of which is

thickened in the middle, the tail dilated into a broad, nearly

equilateral triangle, the base of which extends nearly to the

outer angles of the front ; vesicle with two yellowish or bluish

spots; eyes connected in a long space; occiput very small,

yellowish or brownish ; back of head black. Thorax green

above, brown on the sides, interalar area spotted with greenish

white ; no antehumeral or humeral bands, but on the sides

there is a rather narrow oblique greenish-yellow band under

each wing, not extending to the legs. Legs black; the coxe

and trochanters and the anterior femora beneath at the base

reddish. Abdomen slender, inflated at base and constricted

afterwards ; oreilettes small, acute, the apex incurved; when

adult the general colour is blackish brown, paler at the base ;

on the sides the apex of segment 1 and base of segment 2

are occupied by a greenish-yellow transverse band divided by

the black suture; there are indications of pale apical and

subapical spots on segments 4 to 7; above there is a large

and nearly round median pale spot on each side of 10 and an

apical spot on 7 to 9 (a less mature male shows a whitish

lateral band on segments 1 and 2 and half of 3, and a small

dorsal spot on each side of the false suture on segments 2 to 7,

the apical spots less distinct) ; tenth segment with a median

dorsal carina, which near its base is elevated into a strong

triangular black tooth, with a tubercle placed in a fovea on

either side of it; superior appendages (5 millim.) as long as

the ninth and tenth segments united, black, slightly curved

and narrowed at the base internally, the inner edge forming

a gradual curve to the apex, which is narrower than the base,

acute, and curved downward ; there is a strong median carina

from base to apex, dilating almost suddenly at the com-

mencement of the apical third, the internal edge fringed with

long hairs ; inferior appendages more than one half shorter,

elongately triangular, slightly notched at tip, curved upward,

brownish above. °

Wings hyaline; pterostigma very small (8 millim.),

ochreous, surmounting 25 cellules; membranule conspicuous,

smoky black, with whitish base; nodal sector suddenly

elevated under the pterostigma; subnodal sector furcating

before the level of the pterostigma, 3 rows and 5 marginal

cellules between its branches; 3 or 4 rows of cellules between

the subnodal and the interposed sector at the widest part;

one row of cellules between the sectors of the triangle (more

towards the apex) in the anterior, two rows and afterwards

one in the posterior; no basal subcostal nervule; 15 to 17

of the Subfamily Aischnina. 411

antenodals and 7 to 9 postnodals in the anterior and 10 or 11

and 8 to 10 in the posterior; 5 (rarely 6) cellules in the

principal triangle in anterior and 4 (rarely 5) in posterior, 2

(rarely 1) in the inner triangle ; 2 to 4 supra-trigonals, 3 or 4

in the median area ; anal triangle 3-celled.

Length of abdomen (cum append.) 49 millim. ; length of

posterior wing 44 millim., greatest breadth 14 millim.

Hab, Delagoa Bay, two males.

This insect is clearly an Anacteschna (distinct from A. jas-

ptdea), but the lateral impressions on the sides of the abdo-

men are very faintly indicated *.

Gynacantha } khasiaca, sp. n.

3. Face dingy yellowish, almost fumose, a strongly defined

black T-spot on the top of the front, which is otherwise con-

spicuously pale (yellowish) ; occiput minute, blackish, its

margin raised; back of head yellowish, eye-margins blackish.

Thorax dark greenish above, dorsal crest black ; sides some-

what more yellowish, with indications of two narrow blackish

bands, one on the humeral suture, the other on the interalar

suture. Legs pitchy black ; anterior coxv and trochanters and

anterior femora internally brownish. Abdomen moderate, the

basal portion short and much inflated, considerably constricted

at the third segment; oreilettes large, rounded, black, the edge

with five or six coarse teeth; general colour black above,

venter brownish on a portion of the third to seventh seg-

ments, the sides of segments 1 and 2 varied with greenish ;

tenth segment with a fine, slightly raised, longitudinal dorsal

carina not quite reaching the apical margin, which is finely

denticulate and slightly notched in the middle, the apical

portion of the segment transversely excavated, and at the

* As a modification of Dr. Karsch’s system I think it will prove

preferable to cause Anaczeschna to follow instead of precede Gynacantha

&ec. Probably undue importance has been placed on the presence of

lateral imp ‘essions on the abdomen, and I show that in the species above

described they are virtually absent.

+ Gynacantha is here applied in the sense indicated by de Selys in

1883. Mr. Kirby, in his Catalogue, retains the term for species placed

in Triacanthagyna by de Selys, and substitutes Acunthagyna for Gyna-

cantha, Dr. Karsch has objected to this on the ground that, according

to him, there was no necessity for de Selys’s subdivisions. I think, how-

ever, that these subdivisions will be maintained (and others probably be

found necessary). My objection to the change made by Kirby is that

the type or types of Gynacantha and Triacanthygina were first indicated:

by de Selys when he subdivided the former in 1883 (Kirby’s catalogue

was published in 1890) ; he indicated no type of Gynacantha in 1857, as

Kirby seems to imply.

base on either side of the carina there is a strong tubercle;

superior appendages comparatively short and thick (6 millim.),

about as long as the eighth and ninth segments united, black,

externally nearly straight, slightly sinuate before the apex ;

internally they are thick at the base and scarcely excised on

the edge, but triangularly dilated before the apical portion (at

a point where a carina extending from the base finishes),

which latter is very oblique, ending externally in an incurved

sharp tooth; viewed laterally these appendages are gently

curved, the inner edge ciliated; inferior appendages fully

two thirds the length of the superior, very elongately trian-

gular, strongly curved if viewed laterally, the apex slightly

inturned (doubtfully emarginate).

Wings broad and obtuse, hyaline, tinged with yellow at

the base in the subcostal and median areas, brownish in the

former, extending nearly to the arculus in the posterior ;

pterostigma brownish yellow (43 millim.), surmounting 4 or 5

cellules ; membranule small, whitish; neuration moderately

dense, black; subnodal sector furcating much before the

level of the pterostigma, with 3 or 4 rows of cellules between

nodal and interposed sector at the widest part, 2 on the margin ;

one row between the sectors of the triangle; no basal sub-

costal nervule ; 24 antenodals and 24 postnodals in the ante-

rior, and 18 to 22 in the posterior ; 6 cellules in the principal

triangle in the anterior and 5 in the posterior, 2 in the inner

triangle, 6 supra-trigonals and 5 or 6 in the median area ;

3 cellules in the anal triangle.

¢. As in the male, but the abdomen only slightly con-

stricted at the third segment; appendages very slender and

acute, as long as the ninth segment; tenth ventral segment

with two long curved teeth.

Wings becoming fumose, especially at base and apex, in

very adult individuals ; the yellow of the base more strongly

defined than in the male, extending nearly up to the triangles,

and the brown much more evident, extending up to and

beyond the arculus; 25-28 antenodals and 19 or 20 post-

nodals in the anterior, and 21-23 and 20-22 in the posterior.

also have the wings marked with brown at the base) by the

of the Subfamily AAschnina. 413

black legs and the appendages, the long inferior appendages

of G. khasiaca being remarkable.

De Selys (Ann. Soc. Ent. Belg. xxvii. p. 128, 1883) alludes

toa G. nigripes from Thibet as having very acute append-

ages and no markings at the base of the wings, but with no

further indication of characters.

Gynacantha bullata, Karsch.

Of this I possess two males and two females from “‘ Came-

roons” (Rutherford), one male from “ Mahambé” (Ruther-

ford), one male from Cape Coast Castle, and one male from

“West Africa,” without further indication of locality. They

vary considerably in size, but the characters remain very

distinct. In very mature examples the wings are strongly

brownish fumose. The oreilettes are usually wholly black,

but yellow margined with black in less mature individuals.

(A very immature male and female from Sierra Leone are

slightly doubtful.)

N.B.—4ishna africana, Pal. de Beauv. (Ins. Afr. &e.

p- 67, pl. i. fig. 1). The figure indicates a somewhat large

Gynacantha (probably female), larger than G’. bullata ; what

it really is will probably remain problematical, for I am not

aware that the type is extant.

curved inwards towards the apex ; internally densely ciliated

for the whole length, narrow at the base, then very slightly

Hab. Mahambé, West Africa (Rutherford), one male.

This species agrees with the description of G. vestculata,

Karsch, in the 4-celled anal triangle, and tolerably well in

the form of the anal appendages (there is no mention of the

strong elevated carina on the tenth dorsal segment), but its

much larger size, darker colour of the body, yellow base of

the wings, and apparently more constricted third segment

seem opposed to specific identity. It is the largest African

species known to me.

Assuming that G. quadrina is distinct and G. africana

uncertain, G. vestculata is the only described West-African

species I do not possess.

Gynacantha membranalis, Karsch.

This fine species is distributed from the Amazons to Panama.

As an item in the identification of the numerous American

species unfortunately quoted with names in MS. or with “ no

description,” it is well to point out that G. membranalis=

“G, falco, Bates, Selys, MS.”

Gynacantha tibiata, Karsch.

Described from a male from Ecuador. A pair(¢ ¢) in

my collection from Chiriqui (Panama) agree with the descrip-

tion in all essential points; the very short and broad inferior

appendage of the male is, however, very slightly notched in

the middle of the rounded apex. There can scarcely be any

doubt as to the identity.

Gynacantha chelifera (Selys, MS.), sp. n.

from above the top of the front is much elevated and almost

angulate at its summit; T-spot ill-defined, the top evident

blackish ; eyes connected in a very long space, the occiput

flat, very small; back of head yellowish. ‘Thorax yellowish

fuliginous above, paler beneath and on the sides. Legs pale

yellowish, with concolorous spines. Abdomen slender,

segments united, brownish, inserted distantly at the base,

narrow for nearly three fourths of their length (the inner edge

slightly sinuous), then suddenly enlarged into a flattened,

obtuse, spoon-shaped concave apex, the opposing apices con-

tiguous ; viewed laterally these appendages are regularly but

slightly curved; viewed from beneath the dilated apical

portion is convex, but with a circular terminal concave space,

margined by a fringe of cinereous hairs. Inferior appendages

rudimentary (not more than 2 millim.), triangular, whitish

yellow, the apex notched, and produced into a small black

tooth on either side.

Hab. Brazil, Rio Janeiro (fry). One male has been in

my collection for about twenty years with the MS. name here

adopted.

A singular species in its general form, in the appendages,

and in the not constricted base of the abdomen in the male,

possibly pertaining to the group of species placed in Tri-

acanthagyna, Selys,

418 Mr. R. M‘Lachlan on some Odonata

Heliceschna fuliginosa (Selys) , Karsch.

I have before me five males and three females (collected

by the late D. G. Rutherford), as follows :—

(1) One very mature male from Cameroons.—The wings

entirely brownish fuliginous; 25 ante- and 18 postnodals in

the anterior, and 22 and 20 in the posterior. Length of pos-

terior wing 41 millim., greatest breadth 12 millim.

(2) One less mature male (wings not tinged) and one highly

mature male and similar female (wings darkly tinged) from

‘“¢ Cameroons,” and two highly mature and tinged males from

““ Mahambé.”—In these there are about 31 or 32 ante- and

21 or 22 postnodals in anterior wings, and about 24-26 and

23 in the posterior. Length of posterior wing 51-54 millim.,

greatest breadth 15-16 millim.

(3) Two transitional (?) females (one from Old Calabar,

and the other from Cameroons), in which the wings are

strongly marked with blackish fuscous in the costal and sub-

costal areas nearly up to the arculus, and with a large smoky-

yellowish space from the nodus to the pterostigma, extending

half across the wing (somewhat as in Amphiceschna ampla).

— There are 31 or 32 ante- and 23-25 postnodals in the ante-

rior wing, and 24-26 and 26-28 in the posterior. Length of

posterior wing 56 millim., greatest breadth 16 millim. In

these examples the abdomen has conspicuous pale markings

(almost obliterated in the others); the sides of the third

segment are broadly whitish yellow ; a like-coloured geminate

spot at the base of segments 4 and 5 and a half-ring at the

apex of segments 3 to 6. In these also the appendages are

present (broken in the other), very long (11 millim.), some-

what similar in form to the superior pair in the male, but

more slender at the base and less widened afterwards.

It will be seen from the foregoing that the range of size is

almost as given by Dr. Karsch (Ent. Nachr. xix. p. 194)

from a single pair only, and the neural details practically

agree also; but the size is not dependent upon sex, as my

statement proves. ‘The two females (3) with parti-coloured

wings have a different appearance, but I think are not speci-

fically distinct.

It seems to me that the oreilettes in the male are 5- (not 4-)

toothed. On the tenth abdominal segment in the male there

is a slight raised longitudinal median carina, at the base of

which on either side is a transverse elongate fovea with raised

edge externally, and the apical margin is slightly notched in

its middle. The legs have piceous-red femora and black

tibie aud tarsi, In one of the large females there are two

of the Subfamily 7schnina. 419

basal costal nervules before the first thickened nervule in one

anterior wing.

Heliceschna ugandica, sp. n.

General characters as in H. fuliginosa, and apparently not

differmg im anal structure. Colour (excepting the face,

which is dingy) black, paler beneath, the abdomen showing

traces of paler markings (more evident in the female). Legs

wholly reddish piceous, or the tarsi sometimes blackish,

g. Wings hyaline, not tinged; pterostigma black

(3 millim.), surmounting nearly 4 cellules; neuration less

dense, black; two rows of cellules between the branches of

the sector, 4 cellules on the margin; 4 cellules between the

subnodal and the interposed sector at the widest part; a

single row between the sectors of the triangle for the whole

length ; 22 ante- and 13 postnodals in the anterior and 15

and 13 in the posterior wings; 5 cellules in the principal

triangle, 2 in the inner; 5 supra-trigonals; 3 or 4 nervules

in the basal area; anal triangle 3-celled.

@. Wings asin male, but slightly tinged with yellow at

the extreme base; pterostigma brownish yellow (24 millim.) ;

23 ante- and 15 postnodals in the anterior and 17 ante- and

postnodals in the posterior ; two rows of cellules between the

sectors of the triangle for a short distance on the margin in

the anterior only; (other neural details mainly as in the

male).

Length of abdomen, g (cum append.) 49 millim., 2 (ap-

pend. excl.) 42 millim.; length of posterior wing, g 42,

? 43 millim., greatest breadth, g 14, ¢ 144 millim.

Hab. Uganda, East Central Africa (2. P. Denoit, received

from M. René Oberthiir), one male and one female, slightly

immature.

The pair above noticed appear to be specifically distinct by

the very small pterostigma, less dense neuration *, and appre-

ciably broader wings (especially the posterior) when compared

with an example of LH. fuliginosa of practically the same size ;

also in the nearly wholly reddish legs. In the right poste-

rior wing of the female the first postnodal cellule is divided

longitudinally, but exceptionally and not as a continuation

of the subcosta.

Aischna erythromelas, sp. n.

connected in a long space, occiput very small, slightly excised

on its margin, black; back of head shining black. Thorax

dark blackish brown, with black villosity and green markings

as follows:—a broad band on either side of the dorsal crest

interrupted posteriorly by the crest of the antealar sinus; two

spots, one under each wing, not extending to the legs; pectus

brown. Legs black ; coxe, anterior and intermediate tro-

chanters, and anterior femora at base beneath brownish ; claws

red, tipped with black. Abdomen orange-red ; a very distinct

ring at the base of segments 2 to 7, segments 8 to 10 wholly

(excepting some red spots on 8) and a ventral line black ; at

the apex of each segment from 1 to 7 is a greenish ring with

indications of a narrower one on the transverse false sutures ;

margin of tenth segment above slightly excised in the middle

and with a fovea at the insertion of each appendage. Ap-

pendages black (broken) ; tenth ventral segment rounded,

denticulate, with 4 or 5 of the teeth much more prominent

than, and twice the length of, the others; vulvar lamina with

black side-sheaths and strong reddish spine.

Wings hyaline, very shining ; pterostigma small (4 millim.),

black; membranule whitish ; neuration open, black; sub-

nodal sector furcating on a level with the pterostigma (slightly

before in posterior), the space between the branches com-

mencing by a single cellule, followed by two rows, and ending

in 4 or 5 marginal cellules; 5 or 6 cellules in the space

between the subnodal and the underlying interposed sector

in its broadest part; no basal subcostal nervule ; 19 ante- and

15 postnodals in the anterior wings, 13 and 16 in the poste-

rior ; 4 supra-trigonals in the anterior and 3 in the posterior ;

5 cellules in principal triangle in anterior and 4 in posterior ;

5 nervules in the median area in the anterior and 3 or 4

in the posterior (excluding the nervule forming the inner

triangle).

Length of abdomen (evel. append.) 59 millim.; length of

posterior wing 55 millim., greatest breadth of same 17 millim.,

Hab. Sabathu, near Simla (N.W. India), July 1888, one

female.

It will be necessary to see the male before attempting to

define the nearest allies of this magnificent insect; the in-

equality of the teeth on the tenth ventral segment may be

significant.

In this individual the abdomen had been “ prepared” when

fresh by the extraction of the contents and the substitution of

cotton-wool, so that the colours are no doubt more vivid than

of the Subfamily Aischnina. 421

in examples not prepared ; but at the same time they probably

fall far short of the brilliancy in the living insect.

Aischna minuscula, sp. n.

humeral band extending into the sinus, but scarcely reaching

the anterior margin; sides with two broad oblique greenish-

yellow bands, one under each wing, not reaching the legs ;

interalar space and wing-roots spotted with yellow. Legs

black; coxe, trochanters, and femora (except at apex)

base and constricted afterwards; oreilettes small, prominent,

triangular; colour brown, with black sutures ; a broad yellow

band on the sides of segments 1 and 2, an elongate cuneate

dorsal yellow spot on 2; lateral spots on the base of segments

4 to 8; the apex becomes gradually nearly black, with a

large yellow spot above on each side of the apex of segments

4 to 10, vague on 4 to 6, afterwards very distinct, the spots

on 10 being nearly quadrate, with a black margin anteriorly

and posteriorly, and separated by a longitudinal black band

in which is the dorsal carina, slightly elevated near its base

(with a deep fovea on either side), but not forming a tooth if

viewed laterally. Superior appendages (6 millim.) about as

long as the ninth and tenth segments united, blackish brown,

straight, contiguous, narrowest at the base, the inner edge

gradually widening to end of inferior appendage and continued

as a gentle curve almost from base to apex, which latter is

about the same width as base, with the inner margin gently

curved, the outer acute and slightly turned outward; above

towards the apex, and the spots above are found only on

segments 8 to 10, occupying the whole of 10 excepting a

narrow median line; the lateral spots are conspicuous on

segments 6 to 8. Appendages black, formed nearly as the

anterior in the male, but very short (2 millim.) ; tenth ventral

segment with numerous minute black teeth nearly all over

its surface.

Wings as in male, but the costal portion appears yellowish

owing to the more decided pale coloration of the costal ner-

vules ; pterostigma yellowish; 13 ante- and 8 postnodals in

anterior, LO ante- and postnodals in posterior.

[An immature female has a semilunate pale spot on each

side of the second segment on the false suture; the dorsal

with whitish at the sides of segments 1 to 3 and at the base

of segments 4 to 9 (mostly in the form of a spot on each

segment), a whitish lunule above on each side of the dorsal

crest on segment 2. Appendages long (53 millim.), brownish,

in the form of flattened blades, narrowed internally at the base

and rounded at the apex; tenth ventral segment apically

covered with rather dense blackish teeth ; there are mostly

four rows of cellules between the branches of the sector, with

4 cellules on the margin, the neural details otherwise varying

little.

I have examined the types of 4. Hlhoti, Kirby, from

Central Africa, which species is perhaps allied to 4. minus-

cula, but differs in the appendages &c.; it is not possible

to define the form of the spot on the top of the front on

account of the condition.

A. Rileyt, Calvert, should belong to another group, being

much larger and with humeral as well as antehumeral bands.

the posterior; subnodal sector furcated midway between the

nodus and pterostigma; a single row of cellules in the area

between the subnodal sector and the interposed sector below tt.

Type dischna Milnet, Selys (Japan).

The type of 4. Mi/nei is in my collection and is obviously

not a true dischna, differing in its subglobose face, and espe-

cially in the single row of cellules between the subnodal

sector and the interposed sector below it.

According to the system of Karsch (Entom. Nachr. xvii.)

Planeschna seems (in the absence of the male) nearest to the

American Epieschna, which differs from it mainly in the

abdomen not being constricted near the base, in the much

longer triangles, and in the presence of two rows of cellules in

the space between the subnodal sector and that interposed.

? .— Colour. Carapace yellow, variegated with five longi-

tudinal black bands, one median extending from the anterior

border across the tubercle almost to the hinder border, one

on each side passing backwards from the lateral eyes, and

one on each lateral margin, whence patches of the same colour

pass inwards, near the side of the posterior border there is on

each side a distinct patch; terga yellow, with three longi-

tudinal black bands, one in the middle and one on each side ;

these do not spread on to the seventh tergite; tail pale

yellow, except for three rather indistinct fuscous spots on the

lower surface of the second, third, and fourth segments, one

in the middle and a pair at the posterior end; chele yellow,

digits alone black in their basal half; legs yellow, faintly

spotted with black, one spot in the middle of the femur,

another on the patella, and one at the base of the two tibial

segments.

Carapace as long as the first and ha'f the second caudal

segments, finely granular throughout, but not crested; ocular

tubercle low, with smooth ridges.

Terga finely granular, the median crests distinct, granular,

the lateral crests on the last strong and granular.

Sterna smooth, punctured, the last with neither granules

nor crests.

Tail nearly five times as long as the carapace, the fourth

segment a little wider than the fifth, third, and second, and

equal to the first; segments almost smooth, only minutely

granular when examined with a high power; keels all weak

and scarcely to be called granular, the lower surface of the

third, fourth, and fifth segments without visible keels.

Chele almost smooth, the crests very weakly granular ;

hand without crests, smooth, wide, a little wider than the

brachium, the width equal to nearly half the length of the

movable digit, which is only one third greater than the length

of the hand-back ; digits short, unmodified, the movable with

examples of a closely allied though not quite identical form,

from Niomkolo, Lake Tanganyika (A. Carson), which are

not sufficiently well preserved to be satisfactorily identitiable.

The genus Babycurus is of considerable interest from a

taxonomic point of view, on account of the position it occupies

with regard to the other genera of the Buthide and the

stumbling-block that it constitutes in the way of the adoption

of the two classifications of the family that have been pro-

posed by Dr. Thorell and by Prof. Kraepelin. The former

divided the genera into two subfamilies, the Androctonini

and the Centrurini—the former being characterized by the

presence of two lower teeth on the immovable mandibular

fang, while in the latter there is only one such tooth or none.

In my paper on A Revision of the Genera of Buthide”’ *

I ventured to suggest that such a classification was untenablef,

in view of the discovery of many genera of Buthide since

1876, when Thorell wrote; and I further ventured upon the

statement that, in my opinion, the family was not susceptible

of division into groups of the value of subfamilies.

The first opinion 1s, I think, borne out by the classification

proposed in 1891 by Kraepelin, who attributed only a sub-

sidiary importance in his scheme to the dentition of the

mandible, but regarded the so-called tibial spurs and the

dentition of the fingers of the chele as being of primary value.

Taking these two characters into consideration, he split up

the Buthide (Androctonide}) into three subfamilies :—

(1) Androctonini, with a tibial spur on the fourth and usually

on the third leg as well; (2) Isometrini, and (3) Centrurini,

the latter differing from the former in having the additional

external teeth on the fingers of the chele. ‘This use of the

tibial spurs was, to my mind, a great advance in our know-

ledge ; but I do not consider that the difference in the den-

tition between Centrurus and Tityus is sufficient warrant for

referring them to distinct subfamilies. An exactly analogous

* Proc. Zool. Soc. 1890, pp. 114 &e.

+ To be logically consistent Thorell should, I think, have referred his

genera to three categories, namely :—(1) those with two of these teeth ;

(2) those with but one; and (3) those with none. For it is difficult to see

the grounds for uniting 2 with 3 rather than with 1, since, according to

the character cited, it holds an intermediate position between the other

two.

¢ Thorell, and following him Kraepelin, calls the family Androctonide.

I prefer Simon’s name Buthide, on the ground that Androctonus is a

synonym of Buthus.

30*

498 Mr. R. I. Pocock on East-African Scorpions.

difference obtains between the genera Hadrurotdes, Poc., and

Caraboctonus, Poc., as I have already pointed out * , yet no

one regards the character in this case as of more than generic

value. I submit, therefore, that we are logically compelled

to fuse the Isometrini and the Centrurini into one group, and

if a name be required for it the latter, as the older, must be

retained. ‘This reduces Kraepelin’s subfamilies to two 3 but

the further question to be discussed concerns the value that

he attributes to the tibial spurs. According to his table the

genera fall into two groups, namely those possessing tibial

spurs (Androctonini) and those without them (Centrurini in

the wider sense defined above). At first sight this looks

reasonable enough, but, when critically examined, it seems

to me to fail in consistency in just the same way that

Thorell’s system did; for the genus Babycurus occupies an

intermediate position between the two sections. In fact, if

classified according to the pedal spurs, the genera must be

referred to three sections, namely:—(1) those with these

spurs on the third and fourth legs; (2) those, or rather the

one, with them only on the fourth leg ; and (3) those with

them on neither leg. I confess that, in my opinion, if the

Buthide are to be divided into subfamilies upon the presence

or absence of the pedal spur, it will have to be into the

following three :—(1) Buthini, with the third and fourth pairs

of legs spurred; (2) Babycurini, with the third pair not

spurred; and (3 ) Centrurini, with the third and fourth pairs

not spurred. But if exception be taken to this partition of

the genera (and it is certainly, I think, open to criticism), I

see no escape from the conclusion expressed by myself in

1890, that the character or characters which justify the

splitting of the family into subfamilies have yet to be found.

Since 1890, when I wrote an account of the South-African

Buthide contained in the collection of the British Museum

(P. Z. S. 1890, pp. 114-141), several additions have been

made to our series of Babycurus. The first and most im-

portant is a series of six examples from Cette Cama (or Sette

Camma), south of the Gaboon. These are of especial interest,

inasmuch as Karsch’s types of B. Biittnert (Berl. ent. Zeit.

xxx. p. 78, 1886) also came from the Gaboon, though from

a spot called Sibangefarm, which I have so far failed to

discover on the atlases. These specimens, moreover, agree

more closely with the description of B. Bittnert than any

others examined by me. ‘To the colour-characters mentioned

below it may be added that the lower surface of the tail is

* Ann. & Maz. Nat. Hist. (6) xii. p, 329.

Mr. R. I. Pocock on East-African Scorpions. 429

deeply infuscate, especially towards its extremity, though the

upper surface and the vesicle is reddish. The sexes are

easily distinguishable; in the female the hand is barely as

wide as the brachium, its width being about one third the

length of the movable digit * ; the two digits are straight and

in contact; the first segment of the tail is the widest, but

the second, third, fourth, and fifth are equal in width; the

pectines are short and furnished with 18 or 19 teeth. The

largest female measures 66 millim., the carapace being almost

7 and the tail 87. In the male, on the contrary, the hand is

much wider than the brachium (3: 2), its width being nearly

half the length of the movable digit, which is slightly lobate

at the base, while the immovable is somewhat strongly

sinuate ; the tail is wider than in the female, being almost

parallel-sided, the fourth and fifth segments equalling the

width of the first and slightly exceeding that of the second.

In both sexes the tails are perfectly smooth to the touch,

though in reality they are exceedingly finely granular, with

very weak keels. The pectines are longer, with 19 or 20

teeth. Length of largest male 54 millim., of which the cara-

pace is 5°8 and the tail 33.

The examination of these forms has shown me_ that

B. Kirkit, Poc., the type of which, though decolorized, shows

the dark-tinted brachium characteristic of the West-African

species, is closely allied to B. Biittnert, from which it appa-

rently differs merely in the greater exaggeration of its sexual

features, as evidenced by the greater width and smoothness

of the tail. If such characters increase with age I could well

believe the type of B. Kirkit to be nothing but an aged

individual of L. Biittnert.

In the footnote to my description of B. Kirkii mention is

made of a couple of examples of a scorpion from Rio del Rey,

near the Old Calabar River, which were referred to B. Biiét-

ner?; but since seeing the examples mentioned above from

Cette Cama I am compelled to change my opinion about the

identity of the Rio del Rey examples; and since they are

both readily distinguishable either as subspecies or species

from the Cette Cama form which apparently comes nearest

to the typical B. Biittnert, I propose to describe the former as

a new species under the name Babycurus Johnstonii. As

stated in the synopsis below, this form is much darker coloured

than Biittnert, the legs, hand, humerus, and upper surface ot

* On this digit there are eight median rows of teeth, the basal one

being long and undivided ; the outer row consists also of eight, but the

inner of nine, owing to the presence of one near the middle of the basal

row of the median series.

the basal segments of the tail being an exceedingly deep red-

brown, while the trunk is nearly black above. In addition

to this the granulation is everywhere coarser, and the keels on

the tergites, tail, and chele much stronger, the finger-keel on

the hand standing up as a very conspicuous crest. ‘Total

length 62 millim., of carapace 7, of tail 37. Tail moderately

robust, slightly attenuate posteriorly.

form, from the mouth of the Loango, north of the Congo

Scorpio cavimanus, Poc. Ann. & Mag. Nat. Hist. ii. p. 247 (1888).

When I described this species about eight years ago I had

but a couple of specimens for examination—one obtained by

Mr. F. J. Jackson near Kilima Njaro, and the other by

Capt. Speke near Umyamuezi. Since then the British

Museum has been enriched by the receipt of several more

specimens, and amongst them two mutilated males obtained

by Dr. Gregory at Kinani and a place 4 miles to the south

of it. These specimens agree with the types, so far as can

be judged from their condition, except that the hands of the

chele are not so wide as the length of the carapace, the

measurements being in one case 17°5: 16°5 and in the other

16°5:15°5. The pectinal teeth are 14—14 and 15—16.

What I regarded originally as one of the most distin-

guishing characteristics of this species is the curious depression

on the upperside of the hand at the base of the immovable

finger. ‘This feature I now believe to be a mark of the adult

male; at least it is conspicuous in all the six males that I

have seen (examples varying in length from 76-110 millim.),

but is absent in the one specimen of the female sex that the

Museum possesses. The latter was obtained, together with a

couple of males, at Ugogo, halfway between Zanzibar and

Tanganyika, by Mr. E. J. Baxter; she measures 92 millim.

in length, has 13 pectinal teeth on each side, the hand more

coarsely punctured than in the male, but without a depression.

The tail is less than three times the length of the carapace,

whereas in the males it is more.

Prof. Kraepelin (JB. Hamburg. Anst. xi. pp. 67 and 69)

regards Scorpio cavimanus as a “form” of the Abyssinian

Sc. bellicosus of L. Koch from Habab, which, in its turn, is but

a subspecies of the great West-African Se. africanus, Linn.

For myself, however, I prefer to consider even cavimanus and

bellicosus as distinct until accurately sexed specimens of the

latter are brought to light. From the number of its pectinal

teeth (19 or 20) I should be inclined to think the type of deddi-

cosus must be a male; but, if so, there is no evidence that the

432 Mr. R. I. Pocock on East-African Scorpions.

upperside of the hand is excavated in the manner charac”

teristic of cavimanus, and the tail is evidently very much

shorter.

In all the examples that I have examined the spine-

armature of the feet is very constant, consisting of but 7

spines, 4 on the posterior border and 8 on the anterior, in

both cases there being 2 on each lobe, one in its middle, the

other on its inferior angle, while the apex of the lobe is

furnished with stout spiniform bristles, which, when fractured,

resemble small spincs. ‘The same spine-armature is found in

the other East-African species known to me, namely Scorpio

viatoris, Poc. (Ann. & Mag. Nat. Hist. 1890, vi. p.100),

which was described from a specimen obtained by Emin

Pasha, ticketed merely East Africa. Since then the Museum

has received a couple of adult examples (male and female)

from Zomba, Lake Nyassa (//. H. Johnston). These two

show that the sexual characters of this species are very

different as regards the chele from those of Sc. cavimanus,

the chelee of the male, instead of being larger than those of

the female, are longer and lighter, with the hand only as wide

as the length of the hand-back. The female has the sculp-

turing of the hands stronger and the tail shorter, the first and

second segments being shorter than the carapace, whereas in

the male they are rather longer. ‘The male has 13—14

pectinal teeth, the female 13—13; whereas a young female

(77 millim.) from Fwambo (A. Carson) has 14. ‘The adult

male measures 105 millim., the female 100, the carapace in

both cases being 16, the tail in the male 60, in the female 52.

The terga are much more coarsely granular than in cavi-

manus, and the crests which are so conspicuous on the lower

surface of the anterior caudal segments and of the last abdo-

minal sternite in cavimanus are weak or obsolete in Se.

viatoris.

along the anterior and posterior borders.

Terga smooth, somewhat coarsely but very sparsely punc-

tured, the last coarsely granular at the sides, with traces of

Sterna smooth and polished, the last coarsely punctured on

each side of the middle line.

Tail about 34 times the length of the carapace, narrowed

posteriorly, somewhat compressed, the upper surface smooth,

its side-keels high and strongly denticulated on the second,

third, and fourth; lateral surface of segments granular ;

inferior keels on first and second smooth, punctured, on third

weakly granular, on fourth and fifth almost denticulate ;

supero-lateral keel coarsely granular on all the segments.

Vesicle large, granular below, its width equal to the width of

the third segment, its height equal to the width of the fifth

segment ; aculeus stout, strongly curved.

Mandibles with the penultimate tooth of the movable fang

enlarged and nearly as prominent as the apical.

Chele of normal length ; humerus tubercular or denticulate

above and in front, smooth behind and below; brachium

weakly granular and subcostate behind and above, armed

with a few granules below in front, smooth below and

coarsely punctured behind; hand thick and large, with the

lobe strongly produced internally ; very convex above, not

keeled, furnished externally and at the base of the fingers

with smooth, rounded, irregular-shaped low tubercles, which

towards the inner edge of the hand posteriorly fuse into a

reticulated pattern and entirely disappear upon the posterior

part of the lobe, which, as a consequence, is quite smooth ;

the distal half of the inner surface of the hand denticulate ;

hand-back smooth, punctured; lower surface not crested or

keeled, coarsely granular in its distal half.

Legs of first and second pairs with proximal and distal

tibial segments, each armed behind with two spicules; femora

of fourth very feebly granular; tarsus of fourth with its

lower surface armed behind with 8 spines, 2 of which are on

the lobe, 1 on its inferior angle and 1 halfway up, with a

bristle between them, the angle of the lobe being tipped with

bristles; the distal spine on the lower edge of the foot is

close to the lower one on the lobe ; the spine-armature on the

front (or outside) of the tarsus is the same, except that there

are only 3 or 4 spines on the lower edge. The tarsi of the

other feet present much the same armature.

tained by Mr. George Wilson; sandy steppes south of Tzavo,

five more or less mutilated specimens—an adult male, three

females, and a young.

The females vary but little in structure, except that the

legs and palpi are darker in colour and the sides of the cara-

pace distinctly yellowish in the smaller examples; a very

young specimen measuring only 46 millim. has the bands

much narrower and the upper caudal crests smooth. The

pectinal teeth are usually 18.

The males, on the contrary, differ considerably from the

females. ‘The tail is a little longer; the chele, however, are

neither longer nor thinner, but the movable digit is fur-

nished with a large lobe-like tooth, which fits into a corre-

sponding notch on the immovable digit. ‘The terga also are

very distinctly though finely granular, and the carapace is

not so smooth above; the pectines, though larger, do not

appear to be furnished with a greater number of teeth, one

specimen possessing 17 on each side and the other 18.

This interesting new Scorpion is allied to Scorpio exittialis,

Pocock *, from Shoa, in Abyssinia: but in ewttéalis the hand

is entirely covered with tubercles, which are more granu-

liform than in Gregorii; the lower surface of the hand is

furnished with two strong granuliferous crests; the lower

surface of the humerus is coarsely granular, the upper caudal

keels are not strongly denticulate, and, lastly, on the tarsal

lobes there are 3 spines, one above on the extremity of the

lobe, and the others below in the same position as those on

the tarsi of Gregorzi. There seem, moreover, to be fewer

spines on the lower surface of the foot, since on the inner side

of the last tarsus there are only 4 spines, the distal of these

being further from the inferior one on the lobe than in

Gregortt. Inthe adult male of exztialis, moreover, the vesicle

is enormously enlarged, as I have previously stated. Since

writing the description, however, I have had the opportunity

of examining two additional examples of ewztial’s from Shoa.

These are both young, the larger measuring 95 millim. and

the smaller 80. In both the vesicle is small and there is a

tendency on the part of the granules on the hand to run into

crests on the external side, and there are 22—23 pectinal

teeth.

The two species now under discussion are strikingly nearly

allied to Sc. arabicus and Sc. pallidus of Kraepelin; the

former, indeed, recorded from Homran, in Arabia, is very

difficult to distinguish from Se. eaitialis, of which it might

well be the female, and pallidus in many of the points men-

tioned in the description seems to resemble Sc. Gregori?. But

the locality “‘ Baravez,” in Sumatra *, if accurate, forbids

such an identification, quite apart from the fact that Kraepelin

says pallidus resembles fulvipes in the structure of its tail &c.

sides, finely punctured; precoxal plates longish, narrow,

parallel or diverging, armed with four teeth, the inner fused ;

femoral tooth indistinctly dentate.

Tergites smooth, punctulate, from the seventh marginate,

from the fifth to sixth bisuleate; the last without any median

groove. Sternites smooth, marked with a pair of median

impressions, one in front of the other and longer than it, in

addition to two normal sulci; the last two without sulci.

Anal pleure with the process short and tipped with two

spines; anal legs of average length and thickness; femur

without any spine at its distal end, the other spines few in

number, 1 or 2 on the upper inner, 2 or 3 on the under inner

edge, and 2 or 3 on the under outer.

Legs without tarsal spurs ; claws basally spihed.

Length up to about 62 millim.

Loc. Merifano and Leikipia (J. W. Gregory); also Mom-

basa (D. J. Wilson, type).

‘This species is unmistakably nearly related to O. nudum,

Poc. (Ann. & Mag. Nat. Hist. 1890, v. p. 247), from

Madras, the form of the head and maxillipedes, the absence of

spurs on the tarsi, the grooving of the sterna, &c. being the

same in the two species. In O. nudum, however, the terga

are wrinkled and subgranular and there is a spine close to the

apex of the femur of the anal leg. Possibly these distine-

tions will break down with the discovery of fresh specimens.

Orodesmus ellipticus, O. F. Cook.

Loc. Ngatana. One example (type).

During a recent visit to the British Museum Mr. O. F.

Cook, at my request, examined these two specimens and

described them as representatives of two new species. So far

as I know, the descriptions have not yet been published ; but

doubtless they will shortly appear.

paler keels and a pair of indistinctly defined paler spots on

the dorsal surface of the hinder half of the segments ; legs,

antenne, and ventral surface a uniform pale ochre-yellow.

Body broad, nearly parallel-sided, about five times as long

as wide, its upper surface shining and nearly smooth, finely

punctulate.

Keels well developed, nearly horizontal, though with the

posterior angle slightly tilted; the anterior angle convexly

rounded, the posterior acutely produced, though only in the

last five segments is the hinder border directed backwards;

margin around the pore considerably thickened.

Pores looking obliquely upwards and outwards on segments

DB, ¢, 9, LO sail &e.

The dorsalarea between the keels strongly convex.

Tail triangular, with squarely cut apex and an angular

tubercle on each side in front of it.

Lateral surface of segments finely shagreened ; a distinct

inferior crest visible as far as the seventh or eighth, then

dying out and, at most, represented by a small tubercle.

Sternal areas wider than long, longitudinally impressed

and, at the posterior end, transversely impressed between the

legs, the anterior of which are connected by a ridge; the

hinder border studded with long coarse bristles; in the last

leg-bearing segment the pieces of the sternum that support

the legs of the last pair are coxiform, the distance between

the coxze of the legs being less than the length of one of the

coxe. The sternum of the fifteenth (in the male) is furnished

in front with a forwardly directed, small, triangularly pointed

tooth, and a low tubercular tooth at the base of the posterior

leg; that of the seventh produced posteriorly into a widely

rounded basin-shaped hollow, for the reception of the copu-

latory apparatus ; sternum of sixth with an anterior median

triangular tooth, directed obliquely forward and downward.

Legs with strong claw, hairy, especially the lower surface

of the two basal segments, which have at least one long seta

mixed up with shorter ones; tarsus of the first six pairs with

an apical pad.

Copulatory organ with its distal portion curled backwards

beneath the proximal portion (for the rest see figure).

it will fall into one of the many genera which Mr, O. F. Cook has re-

cently projected into literature. Most of these, without diagnoses and

without type species, are at present nomina nuda; but we feel confident

that the publication of them will not be long delayed.

438 Mr. R. I. Pocock on Hast-African Millipedes.

Species allied to this form occur in tropical East Africa as

far to the south as Natal; but, judging from the form of the

copulatory organ, this species is distinct from all that have

been hitherto described.

Tetracentrosternus flavocinctus, sp.n. (P]. XVIII. fig. 5.)

Body black, first tergite margined with yellow, the rest

with a narrow yellow band running from keel to keel along

the hinder border ; posterior half of keels and of tail yellow ;

legs and sterna yellow ; antenne black.

Antenne long and slender, second to fifth segments the

longest and subequal, sixth shorter.

Segments smooth above; keels moderately well developed,

with posterior angle dentiform ; the transverse groove on the

tergite beginning on segment 5, dying out on segment 15

or 16; not beaded, nor is the groove separating the two halves

of each segment; the lateral inferior crest strong and

crescentic, extending as far back as segment 16; the tracheal

tubercles also distinct.

Legs long and slender; trochanter about twice the length

of the coxa and about half that of the femur; the femur,

tarsus, tibia, and patella gradually decreasing in length in

the order named.

Caudal process normal, triangular, with rather widely

truncate apex.

Anal sternite triangular; the two tubercles moderately

large, but not projecting so far as the median apex of the

late.

i Sternal areas in the posterior half of the body furnished

with a spiniform process at the base of each leg; these

gradually die out on the anterior segments.

Length 27 millim., width 4:3.

¢. Asin female, but smaller, thinner, with larger keels,

and little broader yellow stripes ; a broad median erect process

on the sternum of the fifth segment.

Legs unmodified (the pair of the seventh segment absent) ;

tarsi of those at the anterior end of the body padded with

hairs below.

Copulatory feet as in figure.

Loc. Leikipia (¢); Ngatana (¢). A single example

obtained at each spot.

I refer this species provisionally to Tetracentrosternus on

the strength of the spine-armature of the sterna. It differs

from the type of the genus, subspznosus, from Burma, in being

stouter, in the form of the copulatory organ, as well as in

colour. In the presence of spines it also approaches St. Swin-

hoet from China (Chefoo).

SPIROSTREPTOIDEA.

Alloporus sulcatulus, sp. n.

9. Colour of body and head deep black; antenne and

legs reddish yellow.

Head with deep frontal groove; rugose above, coarsely

wrinkled between the antennz and the adjoining area, smooth

just above the labial margin; distance between the eyes

rather less than the diameter of an eye ; eyes acutely angular,

internally composed of about 52 ocelli arranged in about 8

transverse series.

Antenne moderately long, segments gradually decreasing

in length from the second to the sixth.

First tergite wrinkled, punctured and irregularly sulcate

above and at the sides; lateral process much enlarged, pro-

duced forwards into a large rounded angle, with a deep mar-

ginal sulcus, above which there is another very strong sulcus

following nearly the same curvature, with a third strong

sulcus on its postero-inferior angle. The rest of the segments

with posterior part separated by a distinct groove from the

anterior, and strongly though somewhat irregularly longi-

tudinally sulcate from base to summit, as well as ornamented

with less definite sculpturing, the sulci becoming fainter

towards the hinder end; but anteriorly the areas that they

define become at the sides of the body cariniform or tubercu-

liform, as in Lophostreptus ; anterior part of segments trans-

versely cristulate behind, smoother in front ; sterna smooth.

Pores small in the middle of the posterior part of the

segments.

Anal somite.—Tergite punctulate and rugose, scarcely

angular ; valves with thickened and strongly sulcate margin ;

sternite with posterior border nearly transverse.

Number of segments 47.

Length about 70-75 millim., width 7.

dirty white, posterior portion quite black ; head and antenna

paler than posterior half of segments, sometimes brownish

red; legs and anal somite reddish or yellowish brown.

Head densely punctured, though much more coarsely above

than below ; irregularly impressed above the labial border,

frontal sulcus distinct ; labial excision deep, the tooth large.

Eyes furnished with about 44 ocelli arranged in 6 trans-

verse rows.

Antenne punctured, moderately long, slightly incrassate,

the second segment a little the longest, the segments strongly

narrowed at the base.

First tergite densely punctured and rugulose, with a row of

cariniform teeth along its hinder border; laterally these pass

into a series of (6) oblique ridges, which traverse the side of

the segment; this lateral portion evenly narrowed, with

straight anterior border, obtuse anterior angle, and rectan-

cular hinder angle. The rest of the terga with the posterior

part sharply marked off from the anterior, the sulcus being

very deep; the posterior part ornamented with a series of

close-set, smooth, posteriorly dentiform, longitudinal keels,

running from the base of the legs up to the summit; these

keels become smaller, more dentiform, or even tubercular on

the infero-lateral parts of most of the segments, but at the

anterior extremity of the body they are stronger below than

above; these keels are not always even, some being some-

times rather shorter than the others; keels vary in number

from about 33 to 37 on each side, making a total average of

about 70. Anterior part of segment in the middle of the body

closely and finely punctulate above, rather more coarsely below;

in the anterior part of the body the sculpturing of this half

becomes coarser and coarser, and there is a fine transverse

r idg just in front of the groove.

Sterna strongly sulcate transversely ; a fine fringe running

along the posterior border of the terga.

Anal somite not carinate, densely granular; no caudal

process, the border of the tergite evenly convex ; valves with

a strong keel on each side of their suture, running from

summit to base; sternite transverse.

Legs of medium length; each segment furnished below

with one or two apical sete, and a few shorter ones behind

them ; sete stronger on the anterior legs.

Segments 1 to 3 open below, each with a pair of legs; the

fourth without legs, its two sides united in the middle line

below. ‘The generative ducts, at least in the male, opening

upon two small processes lying behind the second pair of legs

at their base.

Mr. R. I. Pocock on Hast-African Millipedes. 441

3. Slenderer than female ; collum not modified ; angle of

mandible larger; feet not padded.

Number of segments about 50.

Length about 50-55 millim.

Loc. Ngatana.

I think there is no reason to doubt that this species is con-

generic with Glyphiulus magnus of Karsch (Zeits. Naturw.

(3) vi. p. 14, 1881), which Mr. O. F. Cook has made the

type of his genus Lophostreptus. ‘The two, indeed, might be

identical but for Karsch’s statement to the effect that the

tergites in magnus are scarcely visibly segmentate, whereas

in L, armatus the sulcus is very deep.

Odontopyge Gregorii, sp. n.

(Pl. XVIII. fig. 7.)

? .—Colour. Segments blackish or very deep green, with

a clearly defined yellow band running along the hinder border

from base to summit; the anterior covered portion yellow,

with a fine median dorsal black line; legs also entirely yellow;

collum or first tergite completely bordered with yellow; an-

tenne yellow at the base, for the rest deep green ; lower half

of head yellow, upper black; anal valves finely margined

with yellow (the green and yellow were probably black and

red respectively before immersion in alcohol).

Head smooth and polished, with a conspicuous frontal

sulcus ; a fine impression running from eye to eye; eyes with

inner angle not very noticeably acute; a shallow impression

close to the socket of antenna on the interantennal area; six

pores above the labial impression and four close to the margin

on each side of it.

Antenne moderately long, with the distal segmenis (4 to 6)

strongly narrowed at the base.

First tergite crossed below with two sulci in addition to the

one that defines the border. The segments finely striolate

above; the transverse sulcus strong and deep, the area in

front of it finely striate transversely, the area behind strongly

grooved longitudinally at the sides ; on the anterior segments

these grooves are deeper and run up above the pores, but

posteriorly they become gradually weaker, do not surpass the

pores, and almost die away.

Sterna smooth.

Pores moderately conspicuous, well behind the sulcus.

Anal tergite not carinate, posteriorly acutely angled; valves

with margins not grooved, the teeth small and vertical ;

sternite triangular.

442 Mr. R. I. Pocock on East-African Millipedes.

Legs with lower surface of all the segments bristly, the

bristles longer at the distal ends of the segments; upper

surface of the legs finely hairy, the hairs more conspicuous

upon the tarsus and upon the basal segments (trochanters) of

the anterior legs; in the anterior half of the body the tro-

chanter of the posterior legs on each segment is flat below,

while that of the anterior leg is compressed.

¢. Resembling female, but thinner, with the sixth seg-

ment a little expanded and the anterior angle of the first more

rectangular.

Legs with fourth (antepenultimate) segment padded below,

the pad larger on the anterior legs, gradually disappearing

posteriorly and scarcely visible on the legs of the last six

segments,

Copulatory foot as in figure; anterior lamina long and

rather slender, notched inferiorly ; coiled portion consisting

of two main pieces—a double flagellum, of which the outer

branch is longer, stouter, and spirally coiled at the tip, while

the inner is much shorter, thinner and simply pointed, and

of a complicated semi-membranous sheath, also double, one of

the branches being leaf-like, with serrate edges and a bifid tip.

Number of segments over 70 (71 or 72).

Length about 85-90 millim.

Loc. Ngatana. Several examples.

Odontopyge semistriata, sp. n.

(PI. XVII. fig. 9.)

Allied to the preceding in most structural details, but

certainly different in the following respects :—

The sides and lower surface of the body reddish yellow,

but the posterior half of the upper surface ornamented with a

black transverse stripe which extends down to the pore,

though it thins off just above this point; when the body is

spirally coiled these black bands are separated by the yellow

colour of the anterior part of the segments, but when the

body is extended, as in crawling, the black stripes are con-

tiguous or nearly so, so that the upper surface of the body

appears to be black; the first tergite with its posterior two

thirds black above; anal tergite black above; valves black

above; face black, rather paler inferiorly ; antenne fuscous,

with the basal two segments pale; legs entirely yellow.

9. Head resembling that of O. Gregori, but with the

transverse stria between the eyes much deeper, very con-

spicuous; the inner angle of the eye more acute; the area

above the labrum distinctly grooved and roughened. No

impressions at the base of the antenne on the inner side.

Antenne with the segments thinner and longer, not strongly

expanded at their distal end.

First tergite laterally more squared, crossed by two sulci,

the lower of which is only a little above the margin. The

rest of the segments finely striolate, but shining, not dull as

in Gregori? ; the areas in front of and behind the sulcus more

elevated than in the last-named. The apices of the anal

valves a little longer and rather thicker.

Legs almost as in Gregorti, but less smooth at the sides

and above; the trochanters not different.

36. With fourth and fifth segments of legs padded; tro-

chanter of posterior leg of each segment thick and flattened

below, anterior compressed. First tergite laterally more

expanded, with anterior angle rectangularly rounded.

Copulatory foot as in figure.

Length about 70 millim.

Number of segments 63 to 66.

?.—Colour (in alcohol) a tolerably uniform olive-brown,

with a deeper band running along the hinder border of the

segments.

Head as in O. semistriata, but more rugulose below, and

the transverse interocular sulcus weaker.

Antenne with long and slender segments.

Collum with one lateral sulcus in addition to the marginal

one, as in semistriata.

Segments segmentate, striolate, and laterally striate, as in

the other species, and showing same position of pores.

Anal segment shorter than in the preceding two species ;

height of the valves exceeding the length of the tergite. In

the anterior third of the body the posterior legs of each

segment have their basal four segments flattened and exca-

vated below.

3. Face smooth and polished below ; first tergite laterally

expanded, convexly rounded anterior angle.

Legs behind the seventh segment, with fourth and fifth

segments padded below, except quite at the hinder end of the

body, where the pad on the fifth entirely dies off and that on

the fourth nearly so ; the coxa and trochanter of the posterior

leg of the segments behind the seventh expanded and flat-

tened below.

South-western Madagascar. A single male specimen,

collected by Mr. Last.

Homopholis heterolepis.

As the specific name chosen implies, this Gecko differs

from the type of the genus in the heterogeneous lepidosis of

the back. Its general agreement in other respects with

HI, Wahlbergit, Smith, is so great that I would alter the

definition of Homopholis rather than establish a new genus,

a course which is, besides, in keeping with that followed

in other cases (e. g. Stenodactylus, Hemidactylus).

General proportions and digits exactly as in Hl. WaAl-

bergiz; forehead concave; ear-opening rather small, oval,

oblique. Snout covered with juxtaposed convex granules,

largest on the sides; back of head finely granulate, with

small round tubercles; rostral twice as broad as deep ; nostril

pierced between the rostral, the first labial, and four or five

scales ; 11 upper and 9 lower labials; a row of chin-shields

in contact with the symphysial and the anterior lower labials,

the median pair rather large and longer than broad. Back

covered with small, juxtaposed, flat granules intermixed with

round or oval, smooth or feebly keeled tubercles, disposed

irregularly ; 16 tubercles in a transverse series in the middle

of the body. Limbs covered with small, juxtaposed, or sub-

imbricate smooth scales; ventral scales small, imbricate,

smooth. ‘Tail cylindrical, tapering, covered with small,

imbricate, smooth scales, above with transverse series of nail-

shaped, smooth, or feebly keeled flat tubercles, below with a

series of transverse shields. Greyish above, with rather

indistinct wavy cross-bars; a dark streak from the eye to the

first cross-bar ; white beneath.

LXIV.— On the Internal Appendices of the Genital Apparatus

of the Orthoptera. By M. A. Frnarp*.

THERE is an entomological question which for some long time

has appeared to require to be taken up, and to which it will

be useful to call attention, namely the internal appendices of

the genital apparatus in male and female insects. I have

during the past three years and more studied this matter, and

have commenced with the order Orthoptera. I have the

honour to communicate to the Academy some of the results

obtained, confining myself for the present to the male organs.

* From the ‘Comptes Rendus,’ tome cxxii. 1896, pp. 894-895.

Genital Apparatus of the Orthoptera. 451

I shall follow in this note the order of progressive complica-

tion of the organs studied.

Male Blattids exhibit no internal appendix to the vasa

deferentia or to the ejecting canal ; this accords with the primi-

tive characters of these insects.

In the Forficulide or Labidure I can confirm the state-

ments of Meinert, accepted by Palmen, namely, that there is

but one vesicula seminalis, that it is dependent on the vasa

deferentia, that these are continued beyond and maintain a

semblance of equal function; but I regard the organ which

Meinert has named the nodiform gland as being nothing more

than an apparatus for propelling the semen.

The family Acrididze comes next: it forms a very special

group, in which the series of modifications are but slightly

marked in the series of genera. There is to be found between

the two vasa deferentia a dozen tubulous ceca, drawn out,

more or less sinuous, and passing from the ejaculatory canal

in which they are inserted as far as the middle of the height

of the testicles; they are arranged in two symmetrical masses,

braced together and fitting the ventral face of the rectum.

One pair only contains spermatozooids, the others contain a

secretion and are (to be regarded as) glands. From the

anatomical standpoint the vesicule seminales are whiter, more

sinuous, more twisted, and gathered into knots at their free

extremity.

The Gryllide exhibit three kinds of appendices to the

ejaculatory canal :—

1. Tubular ceca, to the number of a hundred on either

side, in which spermatozooids are never seen, but only a secre-

tion, which coagulates under the influence of mounting media

and takes on the appearance of a very regular reticulum over

a homogeneous mass, which often occludes a blackish powder

consisting of crystals.

2. A large reniform vesicula seminalis, situate below the

before-mentioned tubes, and in which the spermatozooids are

placed.

3. A pair of prostatic glands on either side of the ejaculatory

canal. In the group Gryllotalpide there are two vesicule

seminales in place of one: these are the organs which some

describe under the name of appendicular glands, and which

may be seen crammed with spermatozooids a little before the

rutting time.

The Locustide exhibit also three kinds of appendices to

the ejaculatory canal: on the anterior part of the latter may

be distinguished a large trunk which bifurcates; each of the

two branches gives off almost immediately two branches,

452 Mr. W. Warren on new

which are directed, one in front, the other behind: the first of

these branches becomes the axis of the glandular tubes of the

Jjirst order so-called ; the second enlarges to form one or two

oval reservoirs, into which there open some hundreds of glan-

dular tubes of the second order so-called. These latter are

barely 60 w in diameter; they are but a third of the size of

the others, but four times more numerous.

In the genera Ephippigera, Meconema, &c. I have noticed

in the midst of the tubes of the second order a special bundle

more strongly coloured, formed by half a dozen ceca.

Lastly, in the Locustide there is to be found a pair of

prostatic glands with a lenticular appearance.

In the Mantide there are four kinds of appendicular

organs :—

1. Some fifty tubular ceca which are glandular.

2. About twenty shorter ceca gathered into knots, which

are also glandular in character.

3. A pair of large vesicule seminales, which are concealed

by the organs before mentioned.

4. A pair of prostatic glands.

From the histological point of view all these organs are, as

a rule, made up of a single layer of cells supported on a

basilar membrane ; around the vesicule a peritoneal envelope

is plainly visible.

There is a further remarkable fact, namely the development

of very tiny crystals in the glandular tubes just before

copulation.

February 26, 1896.—Dr. Henry Hicks, F.R.S.,

President, in the Chair.

The following communications were read :—

1. ‘On the Structure of the Plesiosaurian Skull.” By Charles W.

Andrews, Esq., B.Se., F.G.S.

Owing to the imperfection of the specimens described, various

previous accounts of the Plesiosaurian skull are incomplete, and

differ from one another in important particulars. There is

in the National Collection a fine skull of Plesiosaurus macro-

cephalus which has lately been cleared from the matrix, with a

description of which the present communication is mainly occupied,

though other specimens, which are of assistance in clearing up some

difficulties, are also noticed. The Author particularly considers the

structure of the palate, and only such points in the structure of the

rest of the skull as add to or are at variance. with previous descrip-

tions are considered.

The Author’s observations indicate that a general similarity of

palatal structure among reptiles does not necessarily imply any

close relationship, but the very great resemblances existing between

the Plesiosaurian and Rhynchocephalian palates, reinforced by

numerous other points of resemblance in these skeletons noted by

Baur, lead to the conclusion that the Plesiosauria are descended

from a primitive Rhynchocephalian reptile, as already opined by

Baur, Boulenger, and others.

2. ‘The Fauna of the Keisley Limestone.—Part I.’ By F. R.

Cowper Reed, Esq., M.A., F.G.S.

The Author has examined a very full series of fossils from the

Keisley Limestone of Westmoreland, and proposes to describe the

fauna of the limestone. In this (first) part of the paper a descrip-

tion of the trilobites is given. He recognizes about forty species,

belonging to ten families. Several of the forms are new, whilst

others have previously been described, and many of them occur in

the limestone of the Chair of Kildare and the Zeptena-limestone of

Dalecarlia.

April 29, 1896.—Dr. Henry Hicks, F.R.S.,

President, in the Chair.

The following communications were read :—

1. ‘Descriptions of New Fossils from the Carboniferous Lime-

stone.—I. On Pemmatites constipatus, sp. noy., a Lithistid Sponge.

II. On Paleacis humilis, sp. nov., a new Perforate Coral ; with

Remarks on the Genus. III. On the Jaw-apparatus of an Annelid,

Hunicites Reidit, sp. nov.’ By George Jennings Hinde, Ph.D.,

E.G:S.

I. The Pemmatites, belonging to a genus hitherto only known

from the Permo-Carboniferous beds of Spitzbergen, was discovered

in the Yoredale Beds of Yorkshire by Mr. J. Rhodes, and is the

only fairly complete sponge which has hitherto been detected in the

Yoredale Beds of North-West Yorkshire. The Author gives a full

description of the species.

Il. The Paleacis was found by the Rev. G. C. H. Pollen in the

Carboniferous Limestone and Shale Series, on the banks of the

Hodder, near Stonyhurst. The specific characters of the form are

given by the Author, who then remarks upon the genus Paleacis,

which has been placed alternately with the corals and sponges,

though latterly it has been generally regarded as a perforate coral.

Nevertheless its real characters had not been definitely settled: the

uncertainty, in the Author’s opinion, being due to the fact that some

writers have placed in the genus certain forms which differ widely

from the typical species, and have then defined the characters of the

genus largely from these foreign forms. The Author, in the light

of the information now supplied, gives a fresh definition of the

genus, which appears to represent a distinct family of perforate

corals, in some features more nearly allied to the Favositide than to

the Madreporidee or Poritide.

ILI. The third specimen was discovered by Miss Margery A. Reid

in the Lower Carboniferous Beds of Halkin Mountain, Flintshire,

and is named in honour of its discoverer. A description of it is

given, and it is stated that, notwithstanding certain peculiarities,

the individual pieces correspond so closely with those of the recent

Eunice family that it may well be included in the genus Eunicites.

468 Miscellaneous.

2. ‘Discovery of Mammalian Remains in the Old River-gravels

of the Derwent near Derby.—Part I. By H. H. Arnold-Bemrose,

Esq., M.A., F.G.S.

A few mammalian bones were found in sinking a well at Allenton.

On April &th, 1895, the Authors commenced further excavations,

and were successful in finding the lower jaw, 26 vertebrae, the os

innominatum, left femur, tibia, fibula, caleaneum, cuboid, 1v meta-

tarsal, right fibula, caleaneum, cuboid, 1v metatarsal, astragalus,

left lunare and scaphoid, and portions of ribs of a Hippopotamus,

also part of the breast-bone of an Hlephas, and part of the tibia of

a Lhinoceros. The Hippopotamus-bones were well-preserved, and

probably belonged to one animal. The body was most likely

stranded in an old channel of the River Derwent, and quickly

covered up with sand and clay, but not before the bones were some-

what disturbed. They were found in a dark-coloured sand above

the river-gravel, at a depth of 9 feet 8 inches below the surface.

Mr. Clement Reid found some twenty or more species of plant-

remains in the sand. ‘These plants ‘indicate a moist meadow or

swampy ground, and a temperate climate. The species are all

widely distributed.’

Part II. By R. M. Deeley, Esq., F.G.S.

The deposits in which the bones were found occupy a wide trench

which occurs on the inside edge of a gravel-terrace stretching for

several miles south of Derby, at a height of 15 or 20 feet above

the modern alluvial plain. The gravels are of later age than the

Great Chalky Boulder Clay, and were formed at a time when the

rivers were removing from their preglacial valleys the older Boulder

Clays, with which they had been partially filled. Gravels

of two ages are recognized: (a) recent gravels well stratified,

undisturbed, and covered in many places by a thick layer of brick-

earth; and (0) high-level gravels showing ‘trail’ and contorted

bedding. It is in these latter gravels that the trench containing

the mammalian remains occurs. ‘The deposits occupying this old

waterway and the contorted high-level gravels are placed together

in the same period; and the Author gives reasons for supposing

that they are both of interglacial age, the contortions and surface-

disturbances having been produced during a recent cold period, most

probably by a lobe of ice which passed down the Trent Valley.

Several peculiar physical features of the valleys, such as the flowing

surface-outlines of the higher gravel-terraces, and the occurrence of

lacustrine deposits in the low-level area occupied by Sinfin Moor,

are instanced as supporting this view.

MISCELLANEOUS.

On the Scaly Covering of the Regenerated Tails of Lizards. By

Dr. Franz Werner, Assistant at the Zoological Institute and

Royal University in Vienna.

Tur results of this research are as follows :—

1. The scales of the regenerated tail in certain Saurians, which

Miscellaneous. 469

reproduce themselves with an altered scale-covering, instead of

being constituted, as in the original, phylogenetically oldest forms

of the family in question, on the primary tail, in all newly acquired

parts exhibit an extensive differentiation from the form originally

manifested, tubercle-scales, crests, spines, and keeled scales not being

reproduced.

2. In the regeneration of the tails of all Saurians which repro-

duce them with an altered form of scale, the existing outer segmen-

tation of the scaly coat, as well as the development of the preformed

points of rupture of the skin, together with the differentiation of a

vertebral column, is lost.

3. In some cases in which the scale-covering of the tip of the

primary tail is different from that of the substituted tail the

secondary tail agrees with the normal tail-tip, which consequently

in this respect shows itself really in the original condition.

4, Differentiations of the scale-covering, which are wanting in

the regenerated tails of lizards, such as tubercles, ridges, &c., are

also not to be recognized in the embryos of the same species until

they attain a certain age.

5. The regeneration of the tail generally fails to take place, or

takes place to a very limited extent, when it has undergone a special

differentiation into offensive or prehensile organs.

6. In cases of a second regeneration the tertiary tail agrees

entirely with the secondary so far as the scale-covering is con-

cerned.

7. Within the same family the regenerated tails of all forms

agree, especially in the rule as to the arrangement of the scales.—

On the Mollusca (Prosobranchiata and Opisthobranchiata, Scaphopoda

and Lamellibranchiata) Dredged by the Austrian Deep-sea Expe-

ditions of H.M.S. ‘ Pola’ in the Years 1890-94. By Dr. Rupoir

Srurayy.

The question of the uniformity of the Molluscan fauna of the

greater depths of the Mediterranean Sea (from about 400 metres

onwards), which Fischer asserted and has proved from the results of

the ‘ Travailleur’ Expedition, are confirmed afresh by the dredgings

of the ‘ Pola.” Further, the matcrial obtained is of a kind to

strengthen the conclusions of Dr. v. Marenzeller, recently published,

which, based upon the nature of the various Echinoderms dredged

at different depths and the uniform character of the whole deep-sea

fauna from 200 metres up to the greatest depths, brought out the

fact of the absence of a defined abyssal fauna,

Again, an Atlantic origin has very rightly been ascribed to the

deep-sea fauna of the Mediterranean, from the fact that many

abyssal mollusks of this basin are identical with Atlantic and North-

Atlantic forms and occur in the Tertiary deposits of Sicily and

Italy, and their ingress referred to a time when there was a much

freer communication between the Atlantic and Mediterranean seas

than exists at present (Jeffreys, Fischer).

470 Miscellaneous.

Species having that distribution were dredged by the ‘ Pola.’

In this communication the Gastropoda, and, indeed (with the

exception of the Heteropoda and Pteropoda), the Scaphopoda and

Lamellibranchiata, are discussed. Of these groups there were

in all 120 species dredged. In the Mediterranean expedition

(1.-IV., 1890-93) there occurred 76 species (36 Gastropoda,

3 Scaphopoda, 37 Lamellibranchiata), in the Adriatic expedition

(1894) 63 species (36 Gastropoda, 2 Scaphopoda, 25 Lamellibran-

chiata); 19 species were found in both seas. j

In shallow places more species were naturally dredged than in

deep ; so in every proportion of the fauna with regard to the vertical

distribution of species there must still be reckoned a considerable

decrease of species from above downwards. This decrease is a much

more striking one than in the western part of the Mediterranean,

and it would appear from this, and having regard to the fact that

on many stations at great depths the dredge yielded absolutely

nothing, that the conclusion is justified that the deeper parts of the

Eastern Mediterranean are still poorer than the analogous portions

of the western basin.

The deepest part which still yielded molluscan shells was Station

no. 82, northward of Alexandria, 2420 metres. Here 9 species

were dredged, of which 5 were entirely new to science. One of

these species belonged to a new genus, which, from the horizontal

position of the hinge-teeth, was named Jsorropodon. It is a shell

of inconsiderable size, with a maximum length of 11 millim. and

8:5 millim. in height, and from its external morphology might be

regarded as one of the Veneridw. The relations of the complicated

hinge point, however, to an affinity with Cypricardia lithophagella,

Lam. In a second new form from the same station the author

recognized a representative of the genus Myrina, which up to the

present is only known as coming from North Australia and South

Africa.

The sum total of new species amounted to 9; they comprised 1

littoral of the genus Scalaria, 3 continental of the genera Fusus,

Lyonsia, and Pecchiolia, and 5 abyssal of the genera Taranis, De-

francia, Lucina, Isorropodon (new genus), and Myrina.

12 species which up to the present have only been found in the

Western Mediterranean or in the Adriatic as the result of the

dredging by the ‘ Pola’ must now be regarded as having a distribu-

tion in the eastern basin.

One of the species dredged by the ‘ Challenger’ expedition off the

Azores extends into the Mediterranean—Pleurotoma (Mangelia)

macra, Watson.

Two new varieties of Raphitoma nuperrima, Tib., form links with

Watson’s species Pleurotoma (Mangelia) corallina and Pleurotoma

(Mangelia) acanthodes from the West Indies and the Azores.

Nine species, otherwise, it is true, already long known, are new

to the fauna of the Adriatic.—Sitzungsb. kais. Akad. der Wiss.
