THE NAUTILUS.

Von. XVII. MAY, 1908. No. 1.

TO OUR READERS.

With the present issue, the publication office of THe Nauti.us

is changed from the Wagner Institute, Philadelphia, to the Boston

Society of Natural History, Boston, Mass. This change is in con-

sequence of the appointment of Mr. JoHnson, the Business Man-

ager and Junior Editor, to the curatorship of the Boston Society.

All subscriptions, advertisements and other business communications

should hereafter be addressed to Mr. Jounson, at the Boston

Society ; while MSS. for publication should be sent to Dr. PitsBry,

at the Academy of Natural Sciences of Philadelphia. Books and

papers for review may be sent to either or both of the editors.

MONTANA SHELLS -PYRAMIDULA STRIGOSA.

MORTON J. ELROD.

The various forms of Pyramidula strigosa give a series of exceed-

ingly interesting and widely varied structure. The series found in

western Montana shows plainly the result of different environment.

The different forms of strigosa vary from the large shells along Flat-

head Lake, measuring 24.34 mm. in diameter, to the very small speci-

mens described below. On July 15, 1900, the ascent of Sinyaleamin

mountain was made. At height of 8,500 feet an alpine variety was

found among the loose rock. There was very little vegetation. No

trees were near. They had been left 500 feet below. An occasional

scrubby plant and the lichens of the rocks afford the food. Ten days

later an ascent was made of McDonald’s Peak, fifteen miles further

north in the range. At height of 7,500 feet a hunt was made for

the shells, and the first were found at 7,800 feet, continuing until

nearly 8,500, when the rocks were so large and so steep it was useless.

to search for them.

Finding specimens on the high slopes of two peaks in the same

range, at about the same altitude in each case, seems to indicate that

they are not found lower. At this altitude the summer is short.

The months of June, July, August, with possibly a little of Septem-

ber, is the period of activity. Snow was not far from the specimens

found, In one case, only a few feet from the shells was a large snow

bank.

The slope on McDonald on which they were found lies to the

west. The shells here would receive the sun early in the forenoon,

and the last rays as the sun sank behind the hills would strike the

ridge on which they were living. The conditions were much more

favorable than on Sinyaleamin peak. The snow melts sooner, the

ridge is broader with more pulverized rock and more vegetation.

The absence of snow tempers the winds. The altitude is a few hun-

dred feet lower, which might make a difference.

Search was made for an hour or more for the shells. A large shell

vial was filled, a couple of dozen live ones being placed in a separate

vial, Living specimens on both McDonald and Sinyaleamin peaks.

were proof that they live there at the present. The summit of Mc-

Donald is too rough and broken, without soil or vegetation, for shells.

to live. None were found. |

As these shells show decided differences from any yet collected,

they are here given as a separate variety, and description follows..

They seem distinct enough to mark a separate species.

Pyramidula strigosa Gld., var. alpina n. var.

Shell small; brownish-gray, tending toward light horn color, im

dead shells turning to pearly white; lustre somewhat silky ; shell flat,

little elevated ; lines of growth, under hand lens, fine, an occasional’

increment of growth giving the appearance of sculpturing; suture

well impressed, the periphery well rounded ; aperture nearly circular,

slightly obovate, somewhat higher than wide; markings as in strigosa,

the upper band continuing in the spire, gradually disappearing ; um--

bilicus medium, circular, deep, subcylindric.

THE NAUTILUS. 3

Large diam., 7-10 mm., average of ten specimens, 8.91 mm.;

greatest depth, 3-5 mm., average of ten, 4.34 mm.; aperture, 3.65—

4.38 mm., average of eight, 3.99; whorls, 44.50 mm., average of ten,

4.26 mm. ;

Specimens taken at 8,500 feet, on Sinyaleamin mountain, Mission

Range, Montana. Also taken on McDonald Peak, same range. Alt.

7,800 to 8,500. Types at the University of Montana.

The averages from the seven localities where shells have been col-

lected show very conclusively the effect of altitude on the size of the

- shells. Increase in altitude diminishes the length of the season, the

amount of heat received, the amount of food supply, and the chances

of life. The result is to stunt or dwarf the animals attaining the

heights. This is plainly shown in the sizes of shells at the different

altitudes. As greater altitudes are reached, shells reduce in diameter,

in depth, in the size of the aperture and in the number of whorls.

Young specimens taken from the adults at Flathead Lake had shells

with 2.25 to 2.50 whorls. If all the young at different altitudes start

with the same number when born, the reduction of shell growth in

spirals is easily deduced. The very significant observation is that a

few hundred feet in altitude shows a corresponding reduction in size

_of the shells, The smallest shells are but three-eighths the diameter

of the largest, one-third of the depth, have an aperture two-fifths as

large, and have but two-thirds the number of whorls. The relative

proportions of the largest, from Flathead Lake, to the smallest, on

Sinyaleamin mountain, are seen from the following approximate

ratios :

Largest shells. Smallest shells.

Lhis story, in brief, as brought out by study, is as follows: Pyra-

midula strigosa, var. cooperi, from some source got into the Flathead

Lake region. At this altitude, 3,000 feet, it flourished and grew, but

the slow-moving animals migrated. As they ascended the mountain

sides, following the streams to the banks of the lakes, and then as-

_cended the wooded slopes the difficulties in securing food for exist-

ence became more of a problem. ‘The shorter season required more

hardy animals. Stunting or accidental variation produced smaller

individuals, which would not require so much food on account of the

reduced size. ‘The ascent of the mountain continuing, the reduction

in size became more pronounced, resulting in the specimens as found.

The shells at high altitude are less than one-half the size in any

dimensions, as a consequence being less than one-eighth in volume.

Present collecting shows that all but the two extremes have been by

some perchance killed, although later search may produce the inter-

vening specimens. But in many places in the mountains of western

Montana shells of medium size are found at from 5,000 feet to 6,000

- feet or higher.

Pyramidula strigosa Gld., var. Coopert W. G. B.

This species abounds along the banks of Flathead Lake and along

the banks of lakes in the Mission mountains. At Sinyaleamin Lake,

in this range, altitude about 3,800 feet, they were not uncommon, but

could not be called abundant, Associated with it, but occurring in

very small numbers, was Polygyra townsendiana Lea, var. ptycho-

phora A. D. Br., and Pyramidula solitaria Say. At McDonald

Lake, in the same range and fifteen miles further north, the species

was abundant, in common again with the Polygyra and P. solitarta

Say. Here some two quarts were secured by a day’s search among

the dead leaves and under decaying logs. To gather them was to

crawl on hands and knees among the dense growth of small trees and

underbrush, the interlacing dead branches being a constant hindrance

as well as a menace to clothing. Many live ones were secured. A

large series was gathered which had evidently been killed and eaten

by squirrels. As the pine squirrel, Sctwrus richardsont Buck, was

rather abundant; he is charged with the damage, though it is not

unlikely the little chipmunk, Zamzas sp., takes a part in the work.

This collecting was in July, 1900.

The shells were generally opened at the apex of the spire, a large

opening being made. An occasional shell was punctured at some

other place, but not many. ‘The enemy seems to have discovered

how and where to strike in order to secure the meal with the least

effort. Pyramidula strigosa var. Cooperi had the larger number of

shells thus injured—fifty-four. “Of Pyramidula solitaria fifty were

found cut by animals, and but three of Polygyra townsendiana var.

ptychophora. The two former were much more abundant, and

coopert more conspicuous than solitarta. P. townsendiana were quite

difficult to find, and the small number of injured shells shows how

this affects their mortality through foes. Being of the same color as

the decaying leaves and moss, and for the most part under logs and

debris, they seem to escape their enemies more readily than the two

species of Pyramidula.

Along the banks of the Flathead Lake, near the University of

Montana Biological Station, this species was also found in rather

large numbers. In July, 1899, numbers of shells were found con-

taining young. While they were in colonies, yet the specimens were

much scattered, and it required much care and search to find them.

The search was usually made after a rain, which was the most suit-

able time for finding them, but at the same time the conditions made

the work very disagreeable.

Pyramidula strigosa Gld., a small variety.

Shells entirely different from those mentioned in the preceding

paragraph are found on most of the lower slopes of western Montana.

They fit in between coopert and alpina, but are not found associated

with either variety. Nowhere does it seem abundant. The small

size is probably due to the shortness of the season at which the ani-

mals can live. By July the hills and mountain slopes have become

dry and parched, although in this month there are occasional light

showers. ‘Their dimensions, in millimeters, are as follows for ten

specimens taken at 5,000 feet: Large diameter, 11.95 to 16.73, aver-

age 13.83; depth, 5.30 to 7.40, average 6.12; aperture, 4.72 to 6.67,

average 9.97 ; number of whorls, 4.8 to 5.4, average 6.106.

Pyramidula strigosa Gld., var.

A series of shells was collected on the Tobacco Root range by Earl

Douglass and E. H. Murray, which the writer has examined. An-

other series was taken by Prin. P. M. Silloway, of Lewistown, Fergus

county. ‘These are the only collections of strigosa made in the State

east of the Rocky Mountains, so far as the writer knows. ‘They are

immediately recognized as differing from those west of the divide.

The sculpturing is coarser and they look thicker and more earthy.

They are decidedly greater in depth than those found on the higher

slopes west of the divide. They differ in these particulars also from

the high altitude form alpina. In general shape they are much like

coopert, but very much smaller. The dimensions in mm., average of

ten specimens, are as follows: From Tobacco Root mountains, alti-

tude 7,000 feet. Large diameter, 15.21 ; depth, 9.30; aperture, 7.06;

whorls, 5.05. From Lewistown, altitude 4,792 feet. Large diam-

eter, 16.80; depth, 11.78 ; aperture, 7.66; number of whorls, 5.28.

From the above it will be seen that the specimens at higher alti-

tude are diminished in size, as also in the number of whorls in the

shell, as is the case of those west of the main range.

The following table of comparisons of ten average specimens will

give a better idea of the differences than can be given in any other

way:

In examining the preceding table, it will be remembered that the

specimens from Lewistown and the Tobacco Root mountains were

taken east of the continental divide, all the others from the west

slope. The series ranges from 3,300 to 8,500 feet altitude. There

is a gradual diminution in each measurement, the smallest and high-

est specimens showing about one-third the dimensions of the lowest

and largest, with the whorls diminished almost two, or nearly one-

third.

The two collections from the east side of the range show the same

reduction, but the series is much smaller. I thought there was an

error in the altitude of those from the Tobacco Root range, but as

Mr. Douglass insists there is not, it appears that conditions there

must differ from those prevailing elsewhere in the State.

GENERAL NOTES.

A New Britisu Virrea.—In the last (April) number of the

Journal of Conchology, Mr. B. B. Woodward describes a new Vitrea

from Cheshire, v. rogersi. It stands near v. alliarta and v. helvetica,

and has been identified also as v. glabra. It is named for the late

Mr. T. Rogers of Manchester, who first (1870) found British speci-

mens.

ErrATA.—Owing to the absence of both editors from Philadelphia

during the printing of the April number, some typographical errors

escaped correction on the proofs. On p. 136, 4th line, the first word

should be Hieizan. In the second paragraph on p. 137, the second

word should be dargillierti, and the 16th line from bottom of same

page should begin with a capital M. On p. 189 the term Pelecypods

is misspelled. There are also some other like errors.

WALKER: EASTERN AMERICAN ANCYLI.

THe NAUTILUS.

. Vou. XVII. JUNE, 1908. No. 2.

NOTES ON EASTERN AMERICAN ANCYLI.

BY BRYANT WALKER.

An attempt to determine the Ancyli of Michigan leads necessarily

to a critical study of all the species described from the States east of

the Mississippi. The following notes embody the results of the in-

vestigation, and are published in the hope of stimulating a more

active interest in this most perplexing and little understood group.

The amount of material examined has been considerable. In ad-

dition to that in my own collection, which includes the Jas. Lewis,

DeCamp and Lothrop collections, I have had the entire collections

of Dr. V. Sterki, Dr. R. J. Kirkland, A. A. Hinkley, Jas. H. Ferriss

and Geo. H. Clapp, and through the kindness of Dr. Pilsbry a suite

of seventy-three trays from the collection of the Philadelphia

Academy of Natural Sciences. Jam also indebted to Dr. Pilsbry

for examining the type of Ancylus haldemani, which corrected my

previous conception of that species, and established the validity of

the species described as A. kirkland. Iam also under obligations

to Messrs. Frank C. Baker and Henry Hemphill for valuable

material.

The lack of authentic examples of many of the rarer species has

been a source of great embarrassment. But by process of elimina-

tion and careful study of the original descriptions, it is believed that

in most cases the difficulty has been successfully overcome.

In studying the Ancyli well cleaned specimens are the prime

requisite. ‘They can then be easily separated in the two sections

14 THE NAUTILUS.

characterized by the smooth or striate apex. In differentiating the

species in these groups, the shape and contour of the shell are the

main elements to be relied upon, the sculpture of the surface being an

exceedingly variable factor, which, by itself, cannot in most cases be

considered a specific character. As in all fresh-water forms, a very

large degree of variation must be allowed for. But in spite of this,

it is believed that nearly all the described species should be allowed

to stand, and, although in certain instances it is not always possible

to determine the exact specific relations of particular specimens, yet,

as a rule, the lines between the different. forms.can be drawn with a

reasonably satisfactory degree of certainty.

Bourguignat, in his ‘* Notice sur le genre Ancylus,” in 1853 (J. de

C. IV., p. 63), divided the genus into two subgenera: Ancylastrum,

with the apex inclined to the right, and Velletia, with the apex in-

clined to the left.

Clessin (1882), in the Conchlien Cabinet, considered these two

groups to have only a sectional value. He also restricted Ancylas-

trum to the Eurasian species which group around A. fluviatilis ; and

with the exception of A. fragilis and oregonensis, which he referred

to Velletia, and the large western A. newberryi and patelloides, which

he placed in a new genus, Lanz, included all the North American

species in a separate group, Haldemanta, which he characterized as

follows: “ Shell conical, apex not bent backwards and only slightly

removed from the centre-line of the shell, aperture round or oval.

Type A. obscurus Hald.”

Unfortunately Haldemania is preoccupied, having been used by

Tryon in 1862 (Proc. P. A. N, S., 1862, p. 95) for the group of

Viviparide now known as Lioplax, so that his very appropriate

name cannot be retained.

As has already been shown (Nauti.tus, XVI., p. 85), the North

American species included in Clessin’s Haldemania are divided into

two natural groups, characterized by the presence or absence of apical

sculpture. These groups are, at least, of sectional value, and must

be recognized.

Owing to the uncertainty which still prevails as to just what

Haldeman’s obscurus really is, and the consequent inability to say

with accuracy to which group that species belongs, it does not appear

desirable to retain obscurus as the type of either section. Whenever

an examination of Haldeman’s type shall definitely determine where

THE NAUTILUS. 1D

the species belongs, Haldemania can be written as a synonym of that

group. Until this is done, the matter must rest in abeyance.

Leaving the position of the western species, which are outside the

scope of this paper, for future consideration, I propose to divide the

eastern American species of Ancylus into two sections, characterized

as follows :

Ist. Leevapex, sec. nov.

Shell usually depressed, apex obtuse or sub-acute, smooth. Type:

A. fuscus Ads.

2. Ferrissia, sec..nov. _

Shell usually elevated, apex acute, radially striate. Type: A.

rivularis Say.

Section Levapex.

This section includes all the larger species of Ancylus, which are

characteristic of the lakes and slow-flowing streams of the northern

States, the Mississippi Valley and Florida. They are usually found

on the reeds, dead leaves and submerged timber in such localities,

and are rarely, if at all, found on stones, dead shells, etc., in rapidly

flowing streams, where they are replaced by the species of the section

Ferrissia. With the exception of A. diaphanus and, possibly, A.

obscurus, the species of this group seem to be wholly lacking in the

mountain streams of the Appalachian region between the Ohio river

and Florida.

J. AncyLus Fuscus Adams (1840). Pl. I, figs. 1-9.

Adams’ description calls for a large depressed, elliptical shell,

moderately curved at the sides, with a moderately prominent, obtuse

apex, slightly behind and to the right of the middle ; 732 mm. long,

41 wide and 14 high. No mention is made of the outline of the

slopes. Haldeman states that all these are rectilinear, while

Gould describes the shell as regularly convex. None of these au-

thors refer to the surface sculpture. But subsequent writers have

assumed that the surface was smooth.

Specimens answering these requirements are common, and show

that the species has an extensive range from Massachusetts west, at

least, to the Mississippi Valley and south to New Orleans. I have

not seen any specimens from Kentucky, Tennessee, the South At-

lantic or the Gulf States east of Louisiana.

The very limited amount of material examined from Massachu-

16 THE NAUTILUS.

setts, none of which is typical in size, does not show any considerable

variation in the contours of the shell. But in the west, where it is

an abundant species, there is considerable variation in this respect.

In 1896 (Navrti.vs, IX., p. 189), Dr. Pilsbry described a shell

similar in shape, though narrower and higher, with the surface

ornamented with “ very fine, somewhat irregular, radial striz, more

distinct toward the periphery ” as A. ewgraptus.

The large amount of material examined has forced me to the con-

clusion that ewgraptus is only a ribbed form of fuscus. In almost

every considerable number of specimens, all the variations can be

found from those with a smooth puniaGe through those with the sur-

face more or less radially rippled, to “those with the fine ribs of

typical eugraptus. This variation in the sculpture is not confined to

the western specimens. In two sets of A. fuscus from Winchester,

Mass., in different collections, which, so far as shape and contour is

concerned, are entirely typical, the surface varies from the typical

smooth fuscus to examples with as well developed ribs as the major-

ity of the western ewgraptus. Nor are the western specimens of

eugraptus uniformly higher and narrower than the typical eastern

examples of fuscus. While, perhaps, they average higher than the

eastern specimens, they vary insensibly from the depressed form of

typical fuscus to elevated specimens higher than the typical ewgrap-

tus, so that I have not seen my way clear to separate the eastern

from the western form on any substantial difference in shape.

Assuming the Massachusetts form to be typical fuscus, it may be

described as a depressed, oval or slightly obovate shell, with the left

side more arcuate than the right; anterior and right slopes straight,

posterior and left slopes slightly convex ; apex very obtuse, not ris-

ing above the general outline of the shell, smooth, slightly behind

and to the right of the middle. ‘Translucent horn-color, shining,

Surface with faint growth lines, otherwise smooth or with irregular

and discontinuous transverse ripples which tend to form irregular

radial riblets.

From central New York to the west there appears to be a much

greater degree of variation. The shells tend to become narrower and

more elevated, and with a greater convexity to the left slope. But

throughout the peculiar, rounded, obtuse apex remains as a valuable _

specific characteristic in differentiating it from A. eee dia-

phanus and obscurus. |

THE NAUTILUS. 17

One peculiar form can, I think, be traced directly to the habitat

of the animal. In nearly every lot of western shells are to be found

a number of specimens, very narrow and elongated, with both of the

lateral sides decidedly convex and with the sides nearly parallel.

When placed on a flat surface the shell rests on the middle of the side

and the ends are elevated and arched, giving a trough-shaped appear-

ance to the shell, when placed apex downward. Now, fuscus is a

dweller upon reeds and otber aquatic vegetation. When it lives

on the flat side of a reed or leaf it grows normal in shape and the

peritreme touches the surface all the way around. But when it lives

on a round reed such as Scirpus lacustris, which is narrower than the

full grown shell, it adapts itself to its position and grows to fit the

reed, the ends following the convex surface of its support and the

sides lapping down around the reed itself.

The dimensions of the specimens figured are as follows:

Fig. 1. Length 5.5, width 4, alt. 1.25 mm.

Fig. 4. Length 7.25 width 4.5, alt. 1.75 mm.

Fig. 37. Length 8.25, width 4.5, alt. 3 mm.

Variable within the limits above specified, nevertheless, A. fuscus

is a consistent and well defined species, which need not be confused

with any of its allies. It differs from A. kirklandi by its more de-

pressed and more regularly oval shape and more nearly central, more

obtuse, less prominent and less eccentric apex; from A. diaphanus

by its elongated, oval shape and more obtuse apex and from A. ob-

scurus by its more depressed, less acute and more central apex and

straight posterior outline.

Typically slightly narrower and considerably higher than the

typical fuscus, but subject to great variation in this respect. Figures

subject to less variations than many of the other species, For this

reason I hesitate to refer to it the more elliptical forms from the

western States, which are usually referred to it, but which seem to

me rather referable to <A. kirklandi, and until a larger amount of

material shall have demonstrated the identity of these shells with the

- typical form, prefer to restrict the species to the author’s type, ‘ dis-

tinguished by its circular and flattened form and central inconspic-

uous apex.”’ As thus limited, it is found in the Delaware river at

Easton, Pa., the Ohio river at Pittsburg and Edgeworth, Pa., the

Illinois river, the Tennessee river at Knoxville, Tenn., and the Hol-

ston river, Tenn. The specimens from the last locality are those

quoted without identification by Lewis in his paper ‘ On the Shells

of the Holston River” (A. J. of C., VI., p. 222), and later referred

to ‘‘haldemani ?” (Proc. P. A. N.S., 1872, p. 110). Haldeman’s

description, though brief, is quite to the point, and leaves little to be

added. It may be said, however, that the apex is smooth, the sur-

face smooth or delicately shagreened with fine transverse ripples,

which in none of the specimens examined become sufficiently raised

or connected to be called ribs; the anterior and left slopes are

slightly convex, the posterior and right nearly straight ; the left side

is usually more arcuate than the right and often decidedly so, the

general shape, however, even then remaining subcircular. There is

some little variation in height as shown by the figures, and, in the

more elevated examples, the shell is less circular, the anterior and

left slopes become more decidedly convex and the apex rather less

central, being, as it were, tipped backward by the more rapid growth

and greater convexity of the anterior portion of the shell. The

largest examples seen are from the Ohio river at Edgeworth, Pa., col-

lected by Mr. George H. Clapp. Those from the Holston and Ten-

nessee rivers are decidedly smaller, the example measured from the

Holston being exactly typical in size.

“NEW PISIDIA.

BY V. STERKI.

Pisidium ohioense n. sp.

Mussel minute, equipartite, well inflated, elliptical in outline ;

beaks in the middle, rather broad, rounded, prominent over the

hinge line; superior margin little curved or almost straight, with

slightly marked, rounded angles at the scutum and scutellum ; the

other margins rounded or the posterior subtruncate ; surface some-

what shining, horn colored, very finely and irregularly striate,

usually with a few coarser lines of growth; shell thin, translucent ;

nacre glassy-transparent, muscle insertions slightly marked ; hinge

fine, plate narrow, cardinal teeth fine, lamellar, the right slightly

curved, abruptly thickened and bifid at the posterior end, the left

anterior longitudinal, almost straight, the posterior slightly oblique

or longitudinal and parallel with the anterior and extending to over

about its middle; lateral teeth comparatively stout, their cusps

pointed, the outer ones of the right valve small but well formed ;

ligament rather stout.

THE NAUTILUS. 21

Habitat: A pond near Garrettsville, Portage Co., Ohio; a brook

near Indian mounds, and a very small stream, Kent Co., Michigan.

In December, 1901, Mr. Geo. J. Streator collected several hun-

dred specimens, most of them immature and young. ‘They were re-

garded as a new species and named, but not published, waiting for

more materials. Since then Dr. R. J. Kirkland has secured over

three hundred specimens from the first named place in Michigan, and

half a dozen from the latter. Last March Mr. Streator has again

found a number of examples at Garrettsville, O. Most of the spec-

imens were incrusted with a ferruginous or blackish coating, some-

times very thick.

This Pisidium is remarkable for the position of the beaks, which

are not posterior, a feature also found with Pis. medianum. The

species is somewhat variable in regard to size and shape ; the largest

specimen seen was 2.7 mill. long, and moderately inflated. There

is a more different form, found among the Ohio and Michigan speci-

mens, averaging smaller, 1.7—2.0 mill. long, comparatively shorter,

well inflated, with the anterior part a trifle longer than the posterior,

the anterior end subangular, the supero-anterior slope being slightly

marked, and the color is somewhat lighter.

In one specimen of the more typical form from Michigan, the

beaks are low, flattened on top, or rather impressed, and with con-

centric, elevated ridges around the flattened areas, somewhat like

those of Pis. ferrugineum Pr.

Pis. mainense n. sp.

Published as Pis. walkeri St. var. mainense St. in the NavuTILvus,

XII., p. 79. Since then numerous specimens were collected in

Michigan by Dr. R. J. Kirkland from Reed Lake, Green Lake, Pine

Island Lake and Little Bostwick Lake, and proved distinct from P.

walkert, which is widely distributed and fairly constant. P's. main-

ense is considerably smaller, less elongate, less oblique, the anterior

and posterior parts are less disproportionate in size. ‘The hinge is of

rather the same character as that of walkeri, but in the specimens

examined from both Maine and Michigan, the left anterior cardinal

tooth is rather longer, and the cusps of the laterals are more abrupt,

especially so in the left valve.

Size: Long 3, alt. 2.6, diam. 2.

Long 3.7, alt. 3.1, diam 2.2 (L. Bostwick Lake).

22 THE NAUTILUS.

The original specimens had been collected at several places in

Aroostook Co., Me., by Mr. Olaf O. Nylander.

Pis. costatum n. sp. (fossil).

Mussel small, somewhat oblique, strongly inflated, with three or

four concentric, prominent ridges on each valve ; beaks rather pos-

terior, large, much projecting over the hinge margin, flattened on

top with a sharp, prominent concentric ridge around the flattened

part; outline of the valves rather oval or ovoid, with the supero-

anterior slope somewhat less curved, the anterior end subangular and

the posterior end subtruncate ; surface with fine, irregular striz and

lines of growth between the ridges; shell rather thin; hinge rather

short, stout and compact, plate moderately broad, and short, cardinal

teeth well formed, the right slightly curved, thicker at the posterior

end, the left anterior large, almost straight, ascending obliquely and

the lamella strongly curved up, its posterior part projecting over the

inferior edge of the plate ; the posterior rather parallel with the an-

terior and extending over about two-thirds of the latter; lateral teeth

close to the cardinals and the ligament, short, those of the right valve

stout, pointed, the outer ones very slight, especially so the anterior,

the grooves short and deep, the left laterals moderately stout, high,

pointed ; ligament short and strong.

Size: Long 2.5, alt. 2.1 (with the beaks), diam. 2.3 mill.

Fossil in a marl bed at Monitor, Bay Co., Michigan, in company

with other Pisidia, collected and sent for examination by Mr. Bryant

Walker.

This species seems to stand near Pis. ventricosum Pr., but its beaks

are less posterior, and the outlines are rather different. It also re-

sembles P. scholtzii Cless. as described and figured, with the flattened

beaks. This feature, however, does not seem to be constant. In

two specimens of P. scholtzii which I owe to the kindness of Mr.

Clessin, the beaks are slightly ‘‘ calyculate,”’ but not flattened on top.

Also in a few younger valves of P. costatum, the beaks are less

flattened, and the ribs slighter.

“A PROPOSED STUDY OF GONIOBASIS.

LAWRENCEBURG, IND., May, 1903.

EDITORS OF THE NAUTILUS :

For many years I have been under the impression that the infor-

od &

THE NAUTILUS. 23

mation that now exists and is at the command of the conchologist,

in reference to the genus Gontobasis, both in the form of labeled

collections and literature, is in such shape as to be practically useless

to the average collector for the following reasons :

Ist. That the local collectors and students have in their collections

recorded species and varieties of species, many of which are entirely

due to local surroundings, and which should not be recognized, as

they now are, as distinct species. These have never been brought

together in numbers sufficient to allow of a proper estimate as to

their value as separate species.

2d. That the individual study of this family, in many cases with-

out the means of comparing large numbers of so-called species and

varieties, has resulted in much confusion and caused a prevalent

erroneous conception of their value as species.

3d. That the great difficulty which the study of this family pre-

sents, the liability to error, and the dislike of any one to publish work

which may afterwards prove to be wrong, has deterred many from

putting forward their individual information, which would be of great

value when used in connection with a mass of similar information

from other sources.

With these facts before me, I believe that some step ought to be

taken to at least do something to throw additional light on this large

genus of North American mollusks,

My idea is as follows ; Take George W. Tryon’s Strepomatide of

North America, use his list of the Goniobasis as a basis, and build

up a monograph of the genus on the foundation and along the lines

laid down by him.

Many “species ” very closely related in geographical distribution

are named as such simply from a variation of color, a variation which

exists in almost every known species to a greater or less degree.

With a large collection of my own, with the opportunity of exam-

ining several others of fair dimensions and containing large series ot

Goniobasis, and with a tolerably large proportion of the existing

literature at hand, I am satisfied that with the generous help of

others interested in this matter I may undertake the task, hoping

that some good end may be obtained. I propose to send out to all

students of the subject lists of all the described species of the genus

Goniobasis, requesting them to correct such lists to the best of their

judgment and ability, and to supply me by exchange or loan with

sufficient material, and with such information as may tend to satis-

factorily solve all questions that may arise. By this means I might

hope: to accumulate sufficiently ample and valuable information to

serve forthe eventual publication of an up-to-date work on the subject.

Yours truly, A. C, BILuups.

Notes on Prososrancuiata, No. I, Lororrum.— By H.

Leighton Kesteven. Proc. Linn. Soc. of New South Wales, 1902,

Pt. 3, pp. 443-483, pl. xvii.

This interesting paper again brings before us the old genus 77iton,

which, being pre-occupied, has long been abandoned in Mollusca, but

regarding a substitute there seems to be a very diversified opinion.

The author has gone thoroughly over the ground, adopting Lotoriwm

Montfort, as proposed by Harris (Catl. Tertiary Moll. in Brit. Mus.,

Pt 1 29897):

Montfort’s names are the earliest that can be considered (Conch.

Syst., ii, 1810). Aguillus (type M. cutaceus Linn.) appears on page

579, and Lotortum (type MV. lotorium Linn.) on page 583. The right

to amend Aguillus to Aquilus and to discard it on grounds of uncer-

tain etymology is questionable; still its similarity to Aquila makes

the name less desirable than Lotoriwm, and as only a few pages in-

tervene between the two names, it seems a small matter to discuss,

still strict ruling would probably make Agquillus the generic name.

The author does not agree with Dr. Dall and Simpson (Moll. of

Porto Rico, p. 416), who by elimination makes Septa Perry, 1811,

the type genus of the family Septidg, and recognizing three other

genera, Ranularia and Lampusia Schumacher, 1817, and Lotortwm

Montf.

The author’s statement that, ‘‘the whole of the species included

by Tryon in Triton (sensu strictu), Simpulium, Cymatium and Gut-

turnium, form one natural genus,” is apparent to any one who has

made a study of all the species based solely on conchological char-

acters.

From the figure of Perry’s Septa rubicunda, and the habitat ‘¢ New

Holland”’ assigned, I should consider it 7. australe Lam. and not T.

nodiferus Lam. The apices of twenty-nine species are described and

figured.—C. W. J.

I am in great doubt as to the identification of this species. Hal-

deman’s type, a single specimen, came from the Nolachucky River,

below Greenville, Tenn. It has been cited from Jamaica by Adams,

from St. Thomas and Porto Rico by Shuttleworth and from Guada-

loupe by Fischer. The citations of Crosse (J. de C., xl, p. 88) and

of Dall and Simpson (U. 8. Fish Com. Bull., i, p. 871) of this spe-

cies in their catalogues of Porto Rico mollusca, are based wholly on

the original citation of Shuttleworth. Both Bourguignat and Clessin

question the West Indian localities and Mazé in his ‘“ Catalogue re-

visé des mollusques terrestres et fluviatile de la Guadaloupe,” ete.

(J. de C., xxxi, p. 29, 1883), states that he had neither found it there

himself nor seen it in any of the local collections. More recently,

Dr. W. H. Dall has quoted it from several localities in Florida

(Proc. U. S. Nat. Mus., 1885, p. 273).

Haldeman compares the type with A. rivularis and haldemani and

his outline figure justifies the comparison.

Clessin’s description is substantially taken from Haldeman, the

dimensions given being the same. But his outline figure is quite

different and he has modified his description to agree with his figure,

placing the apex in the last third of the length and calling it ‘ very

obtuse ”’ instead of following the author’s statement ‘‘apex but slightly

projecting, rather’ more than one-third of the shell posterior.” He

26 THE NAUTILUS.

quotes no other localities than those of Haldeman, Adams, Shuttle-

worth and Fischer. His figure is so decidedly different from Halde-

man’s that it would seem to have been drawn from an actual speci-

men, but he does not so state. He also compares obscurus with

diaphanus, saying that it differs only by its more posterior apex.

Pilsbry, in his description of A. eugraptus (NaAutT. ix, p. 189),

compares that species with both fuscus and obscurus.

These are the only references to obscurus that I have been able to

find. The only specimens I have seen, which are at all referable to

this species, are in the collection of A. A. Hinkley, from Volusia

county, Florida, and are said to have been identified by Dr. Dall.

There are eleven specimens in this lot, of which six are A. penin-

sule, the remainder are quite different and may be obscurus. At the

time Dr. Dall’s paper was published, A. peninsule had not been

described and, if these specimens were identified by him, the mixture

of the two forms raises a query not only as to which form he identi-

fied with A. obscurus, but also in regard to the identity of the speci-

mens referred to that species from the several Floridan localities

quoted in his paper. Both of the forms represented in the Hinkley

lot are characteristic, wide, depressed Levapices and such as would

be expected from a lake country, being closely related to A. fuscus.

As has already been stated, the only species of Levapex from the

region from which Haldeman’s type came, that has been clearly

identified, is A. diaphanus. With that exception, all the Ancyli seen

from that region belong to the section Ferrissia. This fact, taken in

connection with Haldeman’s figure and his comparison of obseurus

with rivularis and haldemani, raises a very serious doubt in my mind

whether the Floridan specimens referred to have been correctly

identified. It certainly seems remarkable that so acute an observer

aa Haldeman should have made such a comparison, if he had before

him a shell similar to those of the Hinkley lot.

1 regret that I have not been able to have Haldeman’s type ex-

amined critically in regard to the apical characters. When that is

done, I should not be at all surprised if it proved to be a genuine

Ferrissia. In the meantime, it seems best to describe and figure the

Hinkley shell, as it may be represented in other collections under

this name, leaving the question of its identity with Haldeman’s spe-

cies for future determination. When cleaned, the shell is a light

yellowish horn-color, shining, very thin, fragile and transparent ;

THE NAUTILUS. Pit

depressed, quite regularly oval in shape, the left side being rather

more arcuate than the right; apex subacute, though not much ele-

vated behind the middle of the shell and decidedly turned to the

right; the anterior slope is nearly rectilinear, the right and left

somewhat convex above, concave below and flattening out toward

the periphery ; the posterior slightly concave ; surface with the lines

of growth faint but quite regular, slightly rippled transversely or with

fine radial ribs (in two of the five specimens examined, radial ribs

are developed as strong as in A. fuscus eugraptus). Length (fig. 16)

6.5, width 4.5, alt. 1.5 mm.

It will be observed that while this shell is larger and more de-

pressed than the typical obscurus, the proportion of the length to the

breadth is almost exactly the same. The longitudinal outline, how-

ever, is much nearer to Clessin’s figure than it is Haldeman’s.

_ The affinities of this form are with A. fuscus, kirklandi and penin-

sule. It is, however, more closely related to kirkland? than to the

others and possibly may prove to be a southern development of that

species. It differs, however, by its more depressed, narrower and

more regularly oval shell, and the peculiar concavo-convex outline of

the lateral slopes. From fuseus, it differs decidedly in contour by

reason of the more posterior, more prominent and more excentric

apex and the peculiar lateral slopes. The shape and color are so

entirely different, that there is no reason to confuse the ribbed form

with A. peninsulz, which is found associated with it.

IV. ANCYLUS EXCENTRICUS Morelet (1851). Pl. 1, fig. 19-21.

This species is the sole representative in the United States of a

group of general distribution in the West Indies, Mexico and Central

America, characterized by the prominent, rather obtuse and very

excentric apex and, usually, well-developed radial ribs over the sur-

face. The only recorded localities are Comal Creek, New Braun-

fels, and Barton Creek, Travis county, Texas. Specimens from the

latter locality, collected by Singley, are before me and are larger

than those from Comal Creek, cited by Pilsbry (Naur. ili, p. 64),

and agree almost exactly with the dimensions given by Morelet, the

size of the specimen figured being, length 73, width 44, alt. 2 mm.

A. excentricus is so entirely different in shape from all other North

American species that there is no possibility of confusing it with any

of them. Another peculiarity of this species is the depression of the

28 THE NAUTILUS.

apex. In all other North American species the apex is the point of

greatest altitude, but in excentricus, the highest point of the shell is

anterior to the apex. :

There is some question as t# the specific validity of this form.

Bourguignat (J. de C. iv, p. 175) considered it to be only a variety of

A, radiatus Guilding, characterized by the apex being slightly more

acute. And in this, he has been followed by Clessin (Conch. Cab.,

Ancylus, p. 67). Crosse and Fischer (Miss. Sci. Mex., ii, p. 37)

state that it differs from radzatus by its thinner shell, more pointed

and more excentric apex and the absence of the radiating striae, and

on this account prefer to recognize it as distinct, although admitting

that the two forms are very close to each other. Von Martens (Biol.

Cent. Am., p. 402) also describes the shell as ‘without radial sculp-

ture” and considers it distinct. Pilsbry, in his notice of the New

Braunfels specimens, however, mentions slight indications of most

delicate riblets radiating from the apex. All of the five specimens

from Barton Creek have the radial ribs more or less developed. In

most of them the ribs are stronger along the antero-lateral slopes, the

median portion being nearly smooth or only slightly rippled. In one

example, however, the well-developed ribs extend over the entire

anterior slope.

Under these circumstances, the approximation of the Texan shells

to A. radiatus seems very probable. Whether this is also the case

with the typical form from Guatemala, must remain uncertain until

authentic material can be critically studied. I have not been able

to make any comparison of the Texan specimens with radvatus.

This beautiful species, which is readily distinguished by “its large

size, broadly oval and depressed form, blunt apex and the dense radial

striation,”’

is apparently peculiar to the inland waters of Florida,

where it seems to be very generally and abundantly distributed. In

addition to the original locality, the St. John’s River, specimens have

been seen from Volusia and Manatee counties and from Lake Jessup,

which indicate a general range over the state. It is possible that

some of the localities cited by Dall for A. obscurus (Proc. U.S. Nat.

Museum, 1885, p. 273) belong to this species.

VI. ANCYLUS KIRKLANDIn.s. PI. II, figs. 1-12.

Shell large for the genus, thin, translucent, horn-colored ; broadly

oval or obovate, sides nearly equally curved, ends broadly rounded ;

quite elevated ; apex subacute, behind and to the right of the middle,

and decidedly turned to the right ; posterior and right slopes straight

or slightly concave, anterior slope quite convex, left slope decidedly

convex ; surface with the growth lines regular and distinct and more

or less rippled by transverse wrinkles, which frequently tend to form

feeble, irregular radial riblets.

This fine large species is a well-defined one and has wide range,

extending from Trenton, N. J., west to Hardy, Ark. The specimens

from the last locality were cited as A. haldemani by Pilsbry (Proc.

P. A. N. S., 1900, p. 457), and, from this identification, that species

was placed among those with smooth apices in the NauT. xvi, p. 88.

A recent examination by Dr. Pilsbry of the type of A. haldemani has

shown that that species has a striate apex and, therefore, does not

belong in Levapex at all. A. kirkland? is distinguished by its large

size, decidedly elevated shape and its prominent, subacute apex,

which is decidedly turned to the right. There is some considerable

variation in shape, as shown by the above measurements, some

examples being more elongated with nearly parallel sides. There is

also considerable difference in height. But in all cases the subacute,

prominent apex and the convex, left slope are characteristic, and

always distinguish it from fuscus, in which the apex, even in the

more elevated examples, is always bluntly rounded and the left slope

scarcely convex.

Kirklandi is more nearly related to the Florida shell herein re-

ferred to as obsewrus than to any other species, but differs by its

broader form, greater elevation, more acute and more eccentric apex

and greater convexity of the left lateral slope.

The finest specimens of kirklandi come from Grand River, Kent

county, Mich., where they have been collected in great abundance

30 THE NAUTILUS.

by Dr. R. J. Kirkland, after whom the species is named. The

Arkansas specimens collected by Ferriss are nearly as large. Toward

the east the species seems to diminish rapidly and uniformly in size

to an extent which would almost justify their recognition as a vari-

etal race. Ohio specimens (fig. 4), collected in considerable numbers

by Dr. V. Sterki, are uniformly smaller than the type, while those

from Roaches Run, opposite Washington, D. C., and the Potomac

River at Alexandria. Va. (figs. 7-10), are still smaller than those

from Ohio. <A single example in the collection of the Phil. Academy

from Trenton, N. J., is similar to these, but slightly larger. Were

it not for the intermediate character of the Ohio shells, these speci-

mens would probably be considered a distinct species, characterized

by their small size, proportionately higher and narrower shell and

more convex anterior slope. But as shown by the figures, the larger

and wider Virginian shells grade indistinguishably into the Ohio

form, as that does into the immature specimens of the still larger

typical form. That this difference in size is a local peculiarity is

shown by the fact that in the considerable amount of material col-

lected by Dr. Sterki, both in Ohio (several localities) and in the

Potomac and its tributary, Roaches Run, near Washington, not a

single specimen was obtained which by its greater size would seem

to indicate that the balance of the specimens obtained were immature

shells. ‘There are also several trays in the Academy’s collection

from ‘‘ Washington ”’ similar to those collected by Dr. Sterki. From

Michigan and several other western localities, occasional small and

medium sized, high, narrow specimens have been noticed which,

though larger, seem indistinguishable from the corresponding eastern

form (fig. 10). But these do not seem to be persistent varieties in

any one locality, being usually associated with the usual form of

kirklandi; but rather sporadic individuals which for some reason

have failed to develop normally. It is the occurrence of such speci-

mens, together with the inability to find any marked specific charac-

ter in the eastern forms, except the difference in size, that has caused

me to refrain from giving them varietal rank until additional ma-

terial shall give a better opportunity to pass upon the exact relations

to these various forms.

iP eetonrevions OF NEW JAPANESE LAND SHELLS.

BY H. A. PILSBRY AND Y. HIRASE,

Japonia sadoensis n. sp.

Shell umbilicate, conic, dull dark brown ; sculpture of very deli-

cate, thread-like oblique striz, widely and irregularly spaced, and

numerous regularly spaced spiral cuticular threads, which bear rather

long hairs, very easily rubbed off, being preserved only on the latter

part of the last whorl in some specimens, wholly lost in others.

Whorls 44, very convex, the last tubular, Aperture oblique, circular,

the peristome thin, continuous, in contaet with the preceding whorl

for a very short distance above ; columellar margin slightly expanded.

Alt. 4, diam. 4.7 mm.

Niibo-mura, Sado. Types no. 84768 A. N.S. P.

This species is clearly distinct from /. barbata and citharella Gld.,

described from Oshima in the Riukiu group, and J. musiva Gld., of

unknown locality. Dr. von Mollendorff has recognized Gould’s

J. barbata in specimens collected by Mr. F. W. Eastlake in the

Hakone mountains (Journ. Asiat. Soc. Beng. liv, 1885, p. 67); this

gives another Japanese locality for the genus, but in view of the

geographic separation, I think that the Hakone form wili prove dif-

ferent from that described by Gould from Oshima.

Chloritis tosanus n. sp.

Shell umbilicate, slightly convex above, convex beneath, very

thin, fragile and chestnut-brown; densely sculptured with very short,

darker, curved hairs, arranged in oblique lines as usual, but a little

32 THE NAUTILUS.

irregular in some places. Whorls 45, very convex, separated by a

deep suture, the last whorl large, rounded at the periphery and _ be-

neath. Aperture broadly lunate, slightly oblique. Peristome thin

and unexpanded, suddenly dilated and recurved at the axial inser-

tion, half covering the umbilicus. Alt. 10, diam. 17 mm.

Shiujo-mura, Tosa. Type no. 84415 A. N.S. P., from no. 1015

of Mr. Hirase’s collection.

It is similar to C. perpunctatus, but nearly twice the size. In

C. fragilis the hairs stand about twice as far apart as in this species,

which is the first Chloritis from Shikoku Island.

Kaliella xenica n. sp.

Shell minutely perforate, pyramidal, much higher than wide, the

spire with nearly straight lateral outlines and very obtuse apex ;

thin, yellowish, faintly and finely striate. Whorls 63%, slightly con-

vex, the last obtusely angular at the periphery, convex beneath.

Aperture broadly lunate, the peristome thin, columellar margin re-

flexed. Alt. 3.7, diam. 2.7 mm.

Shukunegimura, Sado. Type no. 84762 A. N. §. P., from no.

1041 of Mr. Hirase’s collection.

This species resembles K. prealta in general shape, but its outlines

are noticeably more convex, the apex is more obtuse, and there are

fewer whorls. (Xenikos, strange.)

A PROPOSED STUDY OF GONIOBASIS.

BY A. A. HINKLEY.

The article in the June NautiLus, under the above heading, by

Mr. A. C. Billups, was read with interest. It is time something

should be done to bring this interesting group of shells out of the

present chaotic condition. The work will be difficult, owing to more

or less variations in all the species and the wide geographical distri-

bution of some, together with the meager description often given and

sometimes drawn from only two or three specimens ; added to this,

some of the types are inaccessible or lost.

There are twenty-four species of Goniobasis listed in G. W. Tryon’s

monograph on Strepomatide as being found north of the Ohio River

or in that stream, viz. :

The specific value of some of the above is doubtful, and to settle

points in question will require large series of specimens, preferably

from the localities where the types were found. I would suggest that

any one who can do so, collect such a series, including all stages of

growth, make a note of the situation where found, and send the same

to Mr. Billups, if he decides to go ahead with the work.

I am sure some new species will be found, but I hope no specimens

will be described as new until their validity is well established.

If the different groups of the Strepomatide could be studied as

thoroughly as Jo has been by Mr. Chas. C. Adams, a large share of

the doubtful species could be eliminated. There are other species

which show nearly as great a variation as the Jo; for instance, Pleu-

rocera canaliculatum Say has a wide variation in form and varies

from a smooth surface to one with two well-developed grooves on the

body-whorl. Angitrema armigera Say is also quite variable in both

form and tubercles, some specimens having a row of double tubercles

on the periphery of the body whorl. Iam strongly of the opinion

that the specimens described by Dr. Lea as Meseschiza grosvenorit

were young Ang. armigera Say; his description and figure fits many

of the young of that species, excepting for the notch, which is prob-

ably abnormal, as Tryon held. Angitrema duttoniana Lea and Lith-

asia downiet Lea may only be variations of Ang. armigera Say ;

specimens I have collected in Tennessee seem to indicate it.

DESCRIPTIONS OF NEW SPECIES OF ACHATINELLIDZ FROM THE

HAWAIIAN ISLANDS.

BY D. D. BALDWIN.

Amastra henshawit n. sp.

Shell dextral, imperforate or subperforate, solid, ovately conical,

apex subacute; surface lusterless, striated with somewhat irregular

lines of growth; embryonic whorls under a lens showing very deli-

cate radiating sulcations. Color varies from light to very dark

brown, the upper whorls generally much darker than the body whorl ;

the ower whorls with traces of a deciduous, brown epidermis.

Whorls 6, somewhat convex, the last one with a light carination at

the periphery ; suture well impressed. Aperture ovate, a little ob-

lique, livid white within ; peristome acute, slightly thickened within,

extremities united with a thin, livid-white parietal callosity ; colu-

mella white, flexuous, abruptly terminating in a thin lamellar plait.

Length 18, diam. 10 mm.

Habitat: South Kona, Island of Hawaii.

Found in damp woods at the roots of ferns and nearly buried in

trash, at altitudes of from 1,800 to 4,000 feet.

We take pleasure in dedicating this shell to Prof. H. W. Henshaw,

formerly of the Smithsonian Institution, Washington, D. C. He

discovered both this and the following species. The Professor is at

present a resident of Hilo, Island of Hawaii, and his explorations are

contributing largely to our knowledge of the land fauna of this island.

Amastra saxicola n. sp.

Shell dextral, imperforate, rather solid, elongately ovate-conic,

apex subacute; surface lustreless, sculptured with delicate growth

lines ; embryonic whorls smooth and polished. Color reddish-brown,

tending to lighter shade on the middle whorls; apex pearly white ;

destitute of the usual fugacious epidermis of this genus. Whorls 7,

slightly convex; suture well impressed. Aperture ovate, a little

oblique, pinkish within. Peristome simple, acute, not thickened

within, extremities joined by a very thin, pinkish parietal callosity ;

THE NAUTILUS. 35

columella white, flexuous, terminating in a moderately-developed

lamellar plait.

Length 203, diam. 10 mm.

Habitat: Kau, Island of Hawaii.

This shell seems to live among and under rocks to an unusual

degree. It is found on old lava flows attached to the under side of

rocks, or in loose soil and trash at the base of bunch grass growing

on lava flows. The locality is very arid.

Amastra senilis n. sp.

Shell fossil, dextral, deeply perforated, the perforation penetrating

to the apex; moderately solid, globose with a short conical spire,

apex acute; surface sculptured with coarse, irregular growth lines,

with a few irregular cross striz or ridges on the three lower whorls ;

embryonic whorls under a lens exhibiting delicate and regular sulca-

tions. Color of the living shell unknown. Whorls 7, convex.

Aperture sinuately oval, a little oblique; peristome simple, acute,

not thickened within, extremities joined by a thick parietal callosity ;

columella terminating in a slight, flexuous fold.

Length 25, diam. 18 mm.

Habitat: Hamakua, Island of Hawaii.

This and the following species were discovered and sent to me by

Mr. Eugene Horner,.of Paauila, Hawaii. They were found at a

place called Palihoukapapa on the Hamakua slope of Maunakea, at

an elevation of 4,000 feet. The shells were imbedded in the earth

about one foot below the surface.

Prof. Henshaw reports other similar localities on the island of

Hawaii where there are extensive deposits of fossilized land shells

about a foot below the surface of humus. Nearly all the known

genera of Hawaiian land shells are represented in these deposits by

species, some still extant, others probably now extinct. The deposit

of earth above the fossilized shells indicates several hundred years

antiquity.

Amastra fossilis n. sp.

Shell fossil, dextral, minutely perforated, somewhat solid; elon-

gately conical, apex rather acute; surface striated with somewhat

irregular growth lines; embryonic whorls under a lens exhibiting

very delicate and regular sulcations. Color of living shell unknown.

36 THE NAUTILUS.

Whorls 7, slightly convex. Aperture oblique, ovate; peristome

simple, very thin, columellar margin slightly expanded over the

umbilicus ; columella terminating in a flexuous thread-like plait.

Length 18, diam. 9 mm.

Habitat: Hamakua, Island of Hawaii.

This shell in shape resembles some of the forms of Amastra turrt-

tella Fer., which is found on the island of Oahu.

NOTES AND NEWS.

We have lately learned, through Mr. Charles Hedley, of the death ©

of two New Caledonian conchologists—RicHarvp RossiTEr, on Jan-

uary 16, 1903, aged 62 years, and JULIEN BrERNIER, March 34d, at

the age of 55 years. Both died at Noumea. Rossiter formed a large

collection of shells, and supplied the types of many new forms to the

editors of the Journal de Conchyliologie, to John Brazier, of Sydney,

N.S. W., his brother-in-law, and to Dr. W. D. Hartman, of West

Chester, Pa. His collection will probably be acquired by the Colo-

nial Museum at Noumea. Julien Bernier was Clerk to the local

Parliament of New Caledonia, and founded the ‘‘ Musée Colonial ”’

at Noumea. Some of his material has been described in the Journal

de Conch. and elsewhere. Placostylus berniert Hartman, and vari-

ous other species discovered by him, preserve his memory.

A New Prevrotomarta.—Mr. Y. Hirase, of Kyoto, Japan, has

recently discovered a new species of Plewrotomaria, related to P. bey-

richi, from which it differs in having much more numerous, distinctly

beaded spiral cords. In shape and color it resembles P. beyrichi.

The new form will ‘be described under the name Pleurotomaria

hiraset.H. A. Piuspry.

ASHMUNELLA THOMSONIANA CooPpER#&.—I have just found this

form living in abundance at Pecos, New Mexico. ‘The greatest

diameter of five specimens measured is 16,15, 15, 15, 155 mm., thus

averaging larger than the original specimens. ‘The basal tooth is

single, with at most a faint indication of doubling.—T. D. A.

TWO NEW MOLLUSKS FROM THE WEST COAST OF AMERICA.

BY WILLIAM HEALEY DALL.

The National Museum has received through the kindness of Mr,

J. S. Arnheim, of San Francisco, several interesting shells collected

by Capt. William Noyes, of San Francisco, of which two appear to

be undescribed.

Sigaretus noyesit n. sp.

Shell depressed, mottled purplish brown above, pale or nearly

white below, pale purplish with two obscure revolving brown bands

internally, nucleus minute, two-whorled, translucent, subsequent

whorls two, rapidly enlarging; surface with obvious incremental

lines, and faint, very fine, partially obsolete, spiral striation ; covered

with a yellowish silky periostracum; suture distinct but not im-

pressed ; axis rather widely pervious, body with a slight, transparent

coat of callus; pillar lip hardly thickened or reflected, general form

gibbous; alt. 10, major diam. 36, minor diam. 26 mm.

Gorgona Islands, Colombia, in the Gulf of Panama.

This species is a West American analogue of S. maculatus Say, of

the east coast, which is more solid, more convex, with much more

conspicuous spiral sculpture, and has the coil of the whorls impervi-

ous or nearly so.

Tonicia arnheimi n. sp.

Shell small, back rather rounded, girdle narrow, naked, yellow

brown; color pale pink with pale brown dotting, two white lines en-

closing a dark brown streak on the dorsal keel of the intermediate

valves; eye spots with a metallic silvery lustre; anterior valve with

seven, posterior with eight notches, the teeth radially striate ; inter-

mediate valves with one lateral notch on each side; interior colora-

tion pinkish white with a magenta axial streak ; sculpture much like

that of 7. crenulata Sowerby, but central areas with much sparser

riblets and no defined central smooth area, the sutural crenulations

stronger and forming 4 wider band, the pleural rugze mostly fore and

aft in direction, the second valve larger than the rest and with a

more conspicuous mesial smooth area. Interior with sinus square

not denticulate. Anterior and posterior plates with obscurely radial

pustules and very numerous eyes. Length 15, lat. 7, height 4 mm.

Capt. Noyes.

This species is clearly of the group of J. crenulatus but is sepa-

rated by sufficiently distinct characters. The brilliancy of the eye

spots, each situated in a deep, minute pit, is very remarkable. There

are on this small creature nearly 1000 of them.

PLEISTOCENE MOLLUSKS OF WHITE POND, NEW JERSEY.

BY FRANK C. BAKER.

The Chicago Academy has recently received from Dr. Stuart

Weller, Paleontologist of the University of Chicago, a collection of

Pleistocene mollusks from the mar] beds of White Pond, near Marks-

boro, New Jersey. The material consists of about a quart of mixed

shells, which, when studied quantitatively, gave some interesting re-

sults. Valvata and Amnicola made up ninety-five per cent. of the

entire lot, the former being forty-five and the latter fifty per cent.

Of the remainder, Planorbis bicarinatus made up two per cent.,

Planorbis campanulatus one per cent., and the rest of the species the

other two per cent. Aplexa was the rarest, there being but two

specimens in the entire lot.

I am indebted to Mr. Bryant Walker for assistance in determin-

ing some of the material. The list of species is as follows:

Pisidium compressum Prime. Normal.

TSE NAUTILUS. 39

Amanicola limosa Say. Very variable and abundantly represented.

Amnicola galbana Haldeman. This characteristic fossil is very

abundant in the White Pond formation. It shows some variation

‘in the height of the spire, but seems to be easily separated from A,

limosa. Several monstrosities of galbana were found in this collec-

tion ; two were scalariform and the others (6) lad the spire variously

contorted, like the forms of Planorbis complanatus figured by Euro-

pean conchologists. One specimen had the spire almost concealed

by the gibbous last whorl. Monstrosities seem to be rare, as only

eight were found in a lot of over two thousand specimens.

Valvata tricarinata Say, var. confusa Walker. This is nearly as

abundant as the Amnicolas. Only a small percentage of the speci-

mens were typical confusa with two well-defined keels, the majority

having the basal keel strongly developed, the upper part of the whorl

being rounded. In some specimens the two keels are so strong that

they form elevated ridges.

Physa ancillaria Say. Not uncommon.

Aplexa hypnorum Linne. Two specimens of a small Aplexa which

seems referable to hypnorum are in the collection. ;

Planorbis campanulatus Say. Typical, but not abundant.

Planorbis bicarinatus Say. Many specimens of this species show

‘a tendency to form spiral lines, similar to those on var. striatus

Baker.

Planorbis deflectus Say. Common and typical.

Planorbis exacutus Say. But one specimen of this species was

found.

Limnea galbana Say. Not common.

Limnza humilis Say. Not common.

Succinea retusa Lea. Not common.

ON CATALOGUING A COLLECTION OF SHELLS.

BY MRS. M. BURTON WILLIAMSON.

When I began to catalogue my shells I used a ledger blank book,

but in time the book looked untidy, as the space was not sufficient for

the addition of species new to the collection that from time to time

40 THE NAUTILUS. -

were added to it. ‘hen I copied the whole list, leaving space for

the introduction of species not listed. But in some cases the blank

spaces were not needed while more space was required for families

and genera not represented in the book. Again I copied the entire

catalogue, excepting the west coast species which I listed on cards to

form a card catalogue. In time this second book began to look far

from neat, so I tried a new plan. I used “ Ward’s Catalogue of the

Mollusca,’? marking with a small mark such species as I had, and

inserted blanks between the printed leaves for species that were not

found in the price list; but this made the pamphlet rather bulky and

also necessitated my looking over two lists, the printed one and the

written one, in order to find if I had certain species. ‘The plan was

satisfactory at first, then I thought out a better one which I will

give you.

T used a patent cover for blank leaves such as students use for

laboratory notes, examination papers, etc., in colleges and schools. |

I bought paper the proper. size for the cover, about eight by ten

inches. This paper had holes stamped out at the right place for the

metal clasps to be inserted. I use ruled paper, as names and locali-:

ties are quickly seen on the same line, but this is a matter of taste, as

dots can mark the space between names of shells and their localities.

The classification is a matter of choice. J use the same as that.’

found in ‘Tryon’s Structural and Systematic Conchology’”’ for.

marine shells, excepting the west coast shells, for which I use an-

other classification. My reason for using Tryon’s is, if I get a shell

from a family new to me I know where to list it immediately by re-.

ferring to the Systematic Conchology, for by constantly studying and

referring to this work I have become tolerably conversant with the

classification.

I wrote only on one side of the paper when making out this new

list, and paged only this side. This left a blank opposite each page

to be used if the page became full. This blank page I numbered

alphabetically to correspond with the numbered page. For example,

if I required the blank leaf opposite page 5, I numbered it 5*, and if

I found it necessary to add new leaves at this place they would be

paged 5°, 5°, 5%, etc. on the left page, on the right 51, 5’, 5°, ete.

The possibility of adding new leaves, one after another, or of taking

out and rewriting the leaves is the strong feature in favor of using

these covers. The use of the alphabet, or as much of it as is needed

THE NAUTILUS. eae i |

in conjunction with the figures, makes repaging from time to time

unnecessary whien tlie book is enlarged.

At the front of this catalogue I have an index of genera arranged

alphabetically. By indexing according to genera much space is

saved and it does not take much time to refer to the page for species

if one does not remember just where the species may be found in the

classification.

For the use of beginners I will tell how I list specimens on a page.

After leaving space at the left hand of each page for the binding of

the leaves with the metal clasps, I write the name of the shell, by

_ whom named and the locality all upon one line, keeping the locality

of each species at the extreme right hand of the page. At the left

hand I write the initials or some letter to indicate from what source

the shell or shells were received, also the number of specimens.

Above the name of the genera and species I write the name of the

family in large letters. I use red ink for this, as the family name is

more prominent in this way. As noted before, if the space for the

specific name becomes too crowded I write upon the opposite page

the name of the specimen I desire to list, indicating this upon the

page where the others are listed. As they are listed specifically ac-

cording to the alphabet the place assigned to it upon the blank page

is the same as upon the page that is filled.

For West Coast shells, as before mentioned, I use cards. When

a new specimen is listed upon a new card it is placed with the names

of the rest of the genus. Any data desired are written ypon each

card. I got my cards cut and a hole punctured in each one by the

thousand.* All cards for the specific name are the same size, those

for the families and genera have an offset at the top. That is,a

raised margin was left at the top of each card, these were raised

sometimes at one end sometimes at the other end, and others had the

margin in the center. When genera are listed upon a few cards the

raised margins would hide each other if they were not placed ata

little distance from each other, but if one generic name is at the ex-

treme right hand of the row of cards in the box or drawer, another

in the middle, still another at the extreme left hand, these generic

names are readily detected by the eye, whereas if they followed one

another all in a row some would be hidden from sight.

- *Itis best to use the cards of the Library Bureau, as they are of uniform

size and quality.

NEW NORTH AMERICAN PISIDIA.

BY V. STERKI.

Pisidium ashmuni n. sp.

Mussel somewhat elongate, moderately inequipartite, scarcely ob-

lique, moderately inflated; superior and inferior margins moderately

curved, supero-anterior slope curved down to the rounded anterior

end situated well below the median line; posterior end subtruncate, —

with more or less of an angle at the scutum; beaks somewhat pos-

terior, rather broad, rounded, moderately elevated over the hinge

margin; surface shining, with microscopic, shallow, rather regular,

crowded striae, and one or a few impressed lines of growth : color

pale horn, shell translucent, thin; hinge slight, plate narrow ; cardi-

nal teeth rather long, fine, lamellar, the right curved with its an-

terior end much shorter and situated much higher up on the plate

than the posterior which is somewhat thickened ; left anterior of the

same shape as the right, rather hook-like at its anterior end, the

posterior oblique, slightly curved and passing over about two-thirds

of the anterior; lateral teeth rather long, produced far beyond the

pointed cusps; outer laterals of the right valve slicht but distinct ;

ligament rather slight.

Size: Long. 2.8, alt. 2.3, diam. 1.6 mill.

Long. 2.3, alt. 1.9, diam. 1.4 mill.

Most specimens are intermediate.

Habitat: San Rafaels, New Mexico, collected by Rev. E. H.

Ashmun, in whose honor the species has been named.

Pis. ashmuni ranges under the abditum group. It is easily recog-

nized, being of about the same size with Ps. splendidulum St. It is

more elongate and its beaks are broader.

Pisidium danielsi n. sp.

Mussel slightly inequipartite, moderately and regularly inflated,

outlines nearly short oval; all margins well curved, or the posterior

subtruncate, anterior end rounded, rather below the median line;

angles at the scutum and scutellum not marked in most specimens,

slightly so in some; umbones little posterior, low, slightly projecting

over the hinge margin, moderately broad, each with a depression be-

low the apex and above a slightly raised, concentric ridge; surface

with somewhat coarse, subregular and sharp strize, and a few coarser

THE NAUTILUS. 43

lines of growth, rather dull and microscopically rugulose; color

grayish white to yellowish horn, in some specimens slightly plumbe-

ous around the beaks; shell moderately thick, nacre white, muscle

insertions distinct but not impressed ; hinge rather stout, plate rather

broad; right cardinal tooth strongly curved over a deep excavation,

its posterior part thickened and grooved to bifid, the left anterior

strongly curved and rather massive, placed rather high up on the

plate, the posterior oblique, curved, its anterior part reaching to or

over the middle of the anterior; Jateral teeth stout, the cusps rather

short, the outer ones in the right valve rather small but well formed ;

ligament strong.

Size: Long. 4.5, alt. 3.9, diam. 2.6 mill.

Habitat: Marsh from a spring on Lake James, Steuben Co., In-

diana, numerous specimens collected by Mr. L. E. Daniels, of the

Indiana Geological Survey, in whose honor the species is named.

During the season of 1902 Mr. Daniels has collected many and in-

teresting Pisidia and Spheria, especially in northern Indiana, a

section from which very little had been known.

The present species has some resemblance with—typical—Pis.

Strengit, but in the latter species tle outlines are more angular, the

beaks narrower and more prominent and rounded, the striation is

finer, and the hinge slighter. Pvs. danielst is of special interest.

From the features of the surface, the beaks and the hinge, there is

no doubt but that it ranges under the same group with P. com-

pressum, kirklandi, cruciatum, fallax, etc., although the rounded out-

lines, the low beaks, and the moderate and regular convexity would

suggest rather the contrary at first sight. Young specimens, how-

ever, have an unmistakable similarity of the outlines with those of

Pis. compressum Pr. In some of. the specimens the beaks are

broader, and the depression and ridge are less marked or almost ob-

solete, just as it is with certain forms of Pis. compressum.

Pisidium obtusale C. Pfr.

At the same place as the preceding Mr, Daniels has collected

numerous specimens which are distinct from all North American

species described, but exactly like Pis. abtusale from several places

of Europe, and appear to be identical with that species. They are

rather large and almost globular; long. 3.6, alt. 38.1, diam. 2.6 mill.

It is to be expected that the same will be found also at other places.

Eulota (Euhadra) euterpe n. sp.

Shell umbilicate, depressed, the upper surface low-conic, lower

surface convex. Last 14 whorls white under a thin yellow cuticle,

which is in part worn off in the type specimen ; the periphery marked’

with a narrow dark chestnut band, the edge of which appears above:

the suture of the penultimate and last whorls; the inside of the um-

bilicus of the same dark color; ¢tnner whorls red-brown, the apex

whitish. Surface rather glossy, rather closely plicate-striate above,

somewhat smoother below ‘the periphery. Whorls 6, slightly con-

vex, regularly and slowly increasing, the last scarcely descending in.

front, distinctly angular at the periphery, the angle almost disappear-

ing just below the lip. Aperture oblique, lunate, white and show--

39, lesser 34.5 mm. ;

Prov. Kunchan, Riukiu. Type no. 1078 of Mr. Hirase’s col-

lection.

This very handsome Huhadra belongs to the group of /. merea-

toria. It is similar to that species in the umbilicus and shape of the:

peristome, and the slow, regular increase of the whorls; but it differs.

from mercatoria in the depression of the whole shell, the more angular

periphery, the finer and closer sculpture, and in coloration. Only

one specimen has been received.

Hulota (Plectotropis) marginata n. sp.

Shell broadly and openly umbilicate, convexly low-conic above,

convex beneath, solid and strong; light brown, surface lustreless,.

sculptured with irregular growth-wrinkles only. Whorls 7, but:

slightly convex, slowly and regularly increasing, separated by a

slightly impressed suture which is distinctly margined above. Last

whorl slightly descending in front, acutely carinate at the periphery,

the keel narrowly impressed on both sides ; base convex, not angular

around the umbilicus, but very suddenly curving into it. Aperture

oblique, nearly as high as wide; the peristome slightly thickened:

84924 A. N.S. P., from no. 1080 of Mr. Hirase’s collection.

A large, solid species, with the keel margined on both sides, and

-projecting a trifle at the suture.

Eulota (Aegista) friedeliana var. peraperta n. v.

Differs from friedeliana from Nagasaki, the type locality, in the

more widely open umbilicus and the noticeably smaller aperture in

shells of the same size. Alt. 9, diam. 17 mm.; width of umbilicus

5.0 mm.

Isshochi, Higo. Type no. 84925 A. N.S. P., from no. 348a of

Mr. Hirase’s collection.

_ Eulota ( Plectotropis) conomphala n. sp.

Shell umbilicate, depressed, low-conic above and below the acute

peripheral keel. Thin, light brown, nearly lustreless, slightly stri-

ated with growth lines, and showing very fine, close, rather indis-

tinct spiral lines under a lens, obsolete in places. On the upper sur-

face there are sparse, short cuticular processes, easily rubbed off.

Whorls 64, slowly widening, nearly flat, the keel of the last whorl

bearing a fringe of cuticular filaments, triangular at their bases.

‘Base angular around the deep, conic umbilicus. Last whorl very

little descending in front. Aperture oblique, the upper margin of

the peristome simple, basal margin thin, very narrowly reflexed ;

columellar margin dilated above. Alt. 9.5, diam. 19.5 mm.

Yakujima, Osumi. Type no. 84926 A. N.S. P., from no, 905a

of Mr. Hirase’s collection.

A very distinct, thin species, noticeably bi-conic in shape, and

angular around the regularly conic umbilicus. It is an interesting

addition to the fauna of Yakujima.

Hirasea planulata u. sp.

Shell imperforate, discoidal with rounded periphery and level

upper surface. Yellowish brown, dull and very densely, very finely

radially striate above, becoming smooth and glossy beneath. Spire

almost level, but the inner whorls are very slightly sunken. Whorls

54 to 53, convex, slowly widening, the last falling a little to the

aperture and noticeably contracted at the lip; the base impressed in

the middle as usual. Aperture nearly vertical, narrowly crescentic,

the lip thickened within by a strong white rib. Alt. 1.8, diam.

3.5 mm., or a little smaller, alt. 1.4, diam. 3.2 mm.

Hahajima, Ogasawara. Type no. 82976 A. N.S. P., from 849b

of Mr. Hirase’s collection.

This was formerly thought to be a small form of AZ. biconcava,

but the study of additional specimens of both show H. planulata to

be constantly smaller, with a nearly level spire, while in biconcava

the spire is conspicuously sunken.

Kaliella incensa n. sp.

Shell almost imperforate, depressed, the spire very low, conic, the

base convex, periphery rounded in fully mature shells; thin, yellow,

translucent and smoothish, under a strong lens seen to be minutely

and closely striate obliquely above, the striz decussate on the earlier

whorls, the base smooth. |

Whorls 33, but slightly convex, the last nearly double the width

of the preceding. Aperture slightly oblique, lunate, the peristome

thin, columellar margin suddenly dilated and reflexed near the axial

insertion, Alt. 1.6, diam. 2.8 mm.

Hakusan, Kaga. Types no. 84788 A. N.S. P., from no. 973a of

Mr. Hirase’s collection.

A small species with few rather wide whorls, the last one rapidly

widening. The columellar lip is more oblique than usual. It might

be placed in Microcystina, but it has the sculpture of Kaliella.

(Incensus, unrecorded.)

Kaliella harimensis var. sadoensis n, var.

This variety is somewhat larger than A. harimensis. It also re-

sembles K. okiana, but the columellar margin is less widely dilated.

It is from Shukunegimura, Sado; types no. 84764 A. N.S. P., from

no. 1034 of Mr. Hirase’s collection.

GEORGE T. MARSTON.

We regret to announce the death of our friend and correspondent,

George Terence Marston. He was born in Chicago, Jan. 31, 1867.

When he was five years of age his father died and his widowed

mother moved to De Pere, Wisconsin, He attended the public

schools and graduated from the high school at the age of fourteen

years. He immediately found employment ina bank at De Pere,

but was soon called to a position of higher responsibility in a bank at

Green Bay. Here his ambition and tempermental intensity of

nature led him to overwork, and after a few years he resigned his

position and sought to regain his health by a vacation at the seaside.

He came to Quincy in 1891 and was employed in the bank of the

State Savings Loan and Trust Company. His clear mind, industry,

mastery of the principles of business and a rare talent for the accurate

and systematic management of details, made him a valued and

trusted man.

Though compelled to devote himself to business, his special.de-

light was in scientific studies, especially conchology. He had col-

lected and had in his cabinet specimens of nearly every species found

in Wisconsin, and cherished a hope of some day being able to have

the time to prepare a work on the mollusks of that State.

His Jast work was in photographing the embryological develop-

ment of the snail, with some very good results. Among his contri- |

butions to the NavuTiLus was an article on the occurrence of Helicina

occulta Say, in Brown county, Wis.

He was married to Helen E. Collins, daughter of W. H. Collins,

Oct. 3, 1898, who with two children survives him.

GENERAL NOTES.

REVIEW OF THE CLASSIFICATION OF THE CYRENACEA. By

William H. Dall. Proc. Biol. Soc., Wash., vol. xvi, pp. 5-8, 1903.

In working over the Cyrenacea for the Memoir on the Tertiary

Fossils of Florida, Dr. Dall found the nomenclature and classifica-

tion of this super-family in much confusion, and while the details are

48 THE NAUTILUS. .

reserved for the memoir a synopsis of the arrangement adopted has

been given in this pamphlet, which deals with the families of

Cyrenide and Spheriide.

In the Cyrenidze twenty-three proposed genera, subgenera and

sections are listed and type specimens with synonyms are given;

to these Dr. Dall has added one new genus and four new sections.

Of the genus Donacopsis Sandberger, 1872, he says: ‘1 suspect

this to be merely a subdivision of Cyrena.”’

Of the family Spheriide fourteen genera, subgenera and sections

are listed with type specimens. Section Cyclocalyx, subgenus

Cymatocyclas, and subgenus Tropidocyclas are new. The three

types are Pisidium scholtzii Clessin, P. compressum Prime, and P.

henslowianum Sheppard.

‘‘ Pera Leach, and Huglesa Leach, 1852, are synonymous with

Corneocyclus s. s.,” and Galileja Costa; Huglesia Leach, 1840;

Pisum Gray, 1847, not Megerele, 1811; Cordula Leach; Pluminina

Clessin; Cycladina Clessin, and Aivulina Clessin, are, according to

Dr. Dall, not separable from Pistdium s. s.—Mrs. M. Burton

LAND SHELLS OF CuRACcAO.—In Mr. Smith’s useful review of

the land shells of this island (Proc. Malac. Soc., London iii, 113)

several species seem to have been overlooked: Cvonella gloynii and

Succinea gyrata, both described by Gibbons in the Journal of Con-

chology II, pp. 135, 186, plate I, Stenogyra octonoides, Pupa fallax,

and Drymeus multilineatus noticed on p. 1386; also Man. Conch.

XIII, p. 29. Perhaps Cronella gloynii belongs to Mr. Smith’s group

Neosubulina. Another species, ‘* Macroceramus tnermis Gundl.,”

is also reported. The dentition of some of these specimens has been

examined by Binney, and proves to be like that of MW. gosset, so that

the Curacao shell is a member of the genus Microceramus. It is no

doubt distinct from the East Cuban Mac. *nermis, and may be re-

lated to or identical with Pineria bonairensis Smith. The latter is

probably a Microceramus, but I have not seen specimens. Mr. Gib-

bons’ note adds six species to the fauna of Curacao, raising the total

number now known to twelve.—H. A. PILsBry.

THE NAUTILUS.

VoL. XVII. SEPTEMBER, 1903. No. 5.

THE SPECIFIC VALUE OF UNIO DECLIVIS, SAY.

BY L. S. FRIERSON.

The synonymy of Unio tetralasmus Say, given by R. E. Call in

the Transactions St. Louis Academy of Sciences, vol. vii, 1895,

page 52, has been very generally followed; wholly by some, and

partially by others. Mr. Call says: ‘‘It preserves its specific

character so generally that it is a matter of great surprise that so

many synonyms should fall under it. ‘The study of the figures,

descriptions and localities above indicated will furnish convincing

evidence of identity. Of the total number [of synonyms] listed

seven came from Louisiana and contiguous territory ; of these seven,

five are from the same state (Lousiana) and of those five two are

from the same bayou.’’ I have faithfully studied the descriptions,

etc., above indicated, together with the shells themselves in their

native habitat, Louisiana, with the result that I find U. declivis

Say, to be readily recognizable as a perfectly distinct species from

the balance of this group, with U. geometricus Lea, as a synonym

(according to Dr. Lea himself). Unio declivis is, moreover, very

rare as compared with the rest of the group, and generally misunder-

stood. In order that students may recognize the shell it is figured

herewith, and the following specific differences noted :

First. It never attains the extreme size of U. tetralasmus as

shown by the following measurements, based on adult specimens of

each : | Sond

50 THE NAUTILUS.

U. declivis, length 85, height 45, diameter 35 mm.

U. tetralasmus, length 133, height 70, diameter 50 mm.

Second. The beaks of U. declivis are more nearly terminal than in

U. tetralasmus (both Say and Lea mention this fact in describing

the species). )

Third. The color of the nacre of U. declivis is ‘‘ purplish” (vide

Say and Lea), while that of U. tetralasmus is always white, very fre-

quently dull, with large blotches of olive-brown. This is’ an in-

variable characteristic of the thousands I have collected.

Fourth. U. tetralasmus Say, is rounded or bluntly pointed pos-

teriorly, with a rounded or obsolete posterior ridge ; while U. dechvis

when perfect is much more acutely rostrate posteriorly, as noted by

Mr. Say, with a ‘‘ subcarinated ”’ posterior ridge.

Finally, these species inhabit different stations, U. declivis being

found in rivers (Say’s type and Lea’s U. geometricus both came from

Bayou Teche, a navigable stream) while U. tetra/asmus invariably

lives in the “ small streams and ponds of the South,” as stated by

Conrad. An apparent exception being Lea’s U. symmetricus which

he said came from (Alexandria, La.) the Red River; but he pro-

cured his shell at second hand from Dr. Hale, who no doubt was in

error, as he assuredly was in the case of other shells said to have

come from the same river. ‘These shells can live in localities where,

from three to six months at a time, there is absolutely no water; in

fact living shells have been thrown out by the plowshare, and-hun-

dreds have been seen killed by fire sweeping over the dried-up

ponds. (See plate III, middle figure.) This ability to withstand

droughts is no doubt a cause for the misunderstanding of the group.

Mr. Simpson, in his ‘‘ Synopsis of the Naiades,” says: ‘‘and if

there were no connecting links, it would be easy to make half a dozen

species out of it.”’ If the species happens to grow in constant waters,

they form more or Jess perfect shells, and are easily seen to be distinct

species. But on account of their drought-resisting abilities and the

preference for small streams in the case of the tetralasmus crowd, it

may easily be seen that a majority of the adult shells have had to

resist droughts and live through a succession of dormant stages.

During these dormant periods, the mantle of tle animal is partially

withdrawn and the deposition of the epidermis and columnar layers

ceases, but the inner nacre is still deposited. ‘The mantle is especi-

ally withdrawn from the end of the prominent rostrated portion of

THE NAUTILUS. 51

U. declivis. In consequence there are produced in this way many

variations and malformed specimens.

A colony of rough, black and corroded U. tetralasmus was taken

from a stream across which a boy could jump, and Bante in a rail-

road tank of fifteen avres, newly made by the K. C. 8. R. R. Two

years after, one of their progeny was taken from ip tank, with a

yellow, smooth epidermis as hard and glossy as glass, and as distinet

from JU. declivis as luteolus is from ligamentinus (see pl. ili, upper

figure).

In this connection, the writer would remark that in an article

published several years ago (NauTitus XI, 3), under the caption

‘“‘Conchological Notes from Louisiana,’’ he spoke of the above-

mentioned difference in habitat of U. declivis and U. tetralasmus.

But at that time all of his specimens were named according to preva-

lent tradition, and he exactly reversed their names.

Like many other young collectors, the writer has in this way sent

out numbers of shells with erroneous names, and helped to make

confusion worse confounded. He hopes herein to correct at least one

of these errors, and at the same time to render justice to that most

excellent naturalist, Thomas Say.

By comparing the figure with that given by Conrad in his Mono-

graphy, page 45 (and on which Mr. Call’s synonymy is based, no

doubt,) it will be seen that the shells of U. declivis and U. tetralas-

mus are utterly unlike.

A NEW SPECIES OF METZGERIA.

BY WILLIAM HEALEY DALL.

The genus Metzgeria Norman, has hitherto been known from a

single species, the pusilla of Sars or alba of Jeffreys. ‘This is re-

ported from the coast of Norway and the northeastern North At-

52 THE NAUTILUS.

lantic in relatively deep water. A: second species from the Santa

Barbara Channel, California, has lately reached me.

Metzgeria californica n. sp.

Shell small, translucent white, with a pale straw-colored, dull,

wrinkled and rather conspicuous periostracum; nucleus small,

smooth, white, obliquely inclined, of nearly two whorls; there are

four or five rounded subsequent whorls separated by a deep, not

channelled, suture; sculpture of about nine-rather prominent,

rounded axial ribs extending from suture to suture and on the last

whorl to the base, separated by wider interspaces and crossed by

numerous subequal spiral threads, covering the whole shell, their

wider interspaces striated by the incremental lines. Aperture about

half as long as the shell, the outer lip sharp, the throat smooth and

white; the pillar white, not callous, with three distinct, oblique plaits

beside the slightly raised margin of the canal, these are only visible

from the side of the aperture; anteriorly the pillar is tortuous,

slightly recurved, open and rather wide. Length of shell 14, of

aperture 7; width of shell 6 mm.

This species is easily discriminated from M. pusilla by its deeper

sutures and more convex whorls, and by having a more tortuous

pillar with three or four distinct oblique plaits instead of only two.

On a direct view, at right angles to the plane of the aperture, the

plaits are invisible, but are perfectly distinct from a point more

laterally situated. The operculum is elongate-quadrate with apical

nucleus. The shell, with other specimens from the same locality,

was sent to the National Museum by J. H. Paine.

Kita-Iwojima, Izu. Types no. 84965, ‘A. N.S. P., from no. 1094

of Mr. Hirase’s collection. < 7

An extraordinary species, very unlike any other yet known from

the region. Kita-Iwojima is one of the Sulphur or Volcano Islands,

a little group lying southwest of the Ogasawara group, and on a line

with the Izushichito group, or ‘‘ Seven islands of Izu.” They were

discovered by Bernard de Torres in 1543, and are governed by

Japan from the Ogasawara Is. Volcanic forces are still active in

this group, which is regarded by Yoshiwara as a continuation of the

Fuji chain, rather than orogenically belonging to the Ogasawaran

volcanic chain.

The following species of land shells have been found on Kita-

Twojima :

Tornatellina inexpectata Pils.

Tornatellina kitaiwojimana Pils.

Tornatellina hataiana Pils.

Opeas gracile ogasawaranum Pils.

Kaliella prealta var. izushichitoensis n. v.

of Mr. Hirase’s collection. Also, Niijima, Izu, no. 1060 of Mr.

Hirase’s collection.

Kaliella nesiotica n. sp.

Shell conic, with very slightly convex lateral outlines, obtuse sum-

mit, acutely thread-carinate periphery and slightly convex base ;

transparent brown. Whorls fully 6, slightly convex, parted by a

suture in which the fine thread-like keel ascends. Sculpture of ex-

tremely minute, rather widely-spaced hair-stria. Aperture basal,

squarish, the columellar margin reflexed above. Alt. 3.6, diam.

are much more widely spaced in this species.

Sitala niijimana n. sp.

Shell minutely perforate, with conic spire, obtuse apex, strongly

_ THE NAUTILUS. ‘BD

angular periphery and convex base; thin, fragile, and of a pale,

somewhat transparent horn-color. Surface faintly marked with

growth-wrinkles, and under very strong magnification, showing an

excessively minute, close decussation of radial and spiral lines.

General outlines of the spire straight. Whorls 35, convex. Colu-

mella reflexed above. Alt. 2, diam. 2.3 mm.

Niijima, Izu. Types no. 84963, A. N.S. P., from no. 1057 of

Mr. Hirase’s collection.

The rather acutely angular periphery is nearly in the middle of

the height of the shell. It is referred to the genus Svtala on account

of its spiral sculpture, which is, however, excessively minute.

NOTE ON THE FAMILY SEPTIDZE.

BY W. H. DALL.

In the Report on the Mollusks of Porto Rico, I adopted for the

family Tritonide of authors, the name Septide, and for the typical

genus the name Septa, proposed by Perry in 1811. Perry’s list of

species comprised six, beside which he mentions the Murex tritonts

of Linné (spelling the specific name tritonia, but his meaning is ob-

vious). His genus was equivalent to the genus 7riton, as used by

authors of the first half of the 19th century. His largest and most

conspicuous species, which he compares with Murex tritonis, belongs

to the same group as the latter, which was generally accepted as the

type of the old genus Zriton and reserved for it by Montfort when he

divided the genus, a year earlier than Perry. Therefore I accepted

Septa rubicunda Perry (—Triton nodiferus Lam.) as the type of

Perry’s genus and applied the name to the congeneric species of

Porto Rico, since 7riton is preoccupied.

In an interesting and useful paper by H. Leighton Kesteven, re-

ferred to in the June number of the NauTILus, the author does not

accept the name Septu because Perry’s first species is a Lotorium and

without argument is taken by Mr. Kesteven as type. He shows very

clearly that the name cannot be used for Lotorium, but does not

observe that I never proposed to so use it. I used it for the group

of Murex tritonis L., which is generically distinct from the group of

which ZLotor‘um is a member, and which, as Mr. Kesteven shows,

56 -_ THE NAUTILUS.

has no other name at present which is valid. I was. not obliged to

take the first species of Septa as a type, knowing it to be a Lotorium,

and did not. The species for which I used it had no valid generic

name and Septa was applicable, and should, I think, be adopted.

San Salvador, or Watling Island, is one of the Bahama Islands,

and lies just north of the Tropic of Cancer. Its molluscan fauna is

like that of the West Indies and Florida. The specimens are mostly

beach shells.

NOTES, NEWS AND REVIEWS.

THE USE OF THE GENERIC NAME HeEticostyLa.—In the dis-

cussion of the nomenclature of ‘‘ Cochlostyla,” it has not been noticed

that Morch, in 1865, used the name Helicostyla to include Axina,

Corasia, Helicobulimus, etc. He gives a new name Pythohelix for

the species boholensis and fulgetrum and misspells Orustia (“ Onistia’’)

and Corasia (‘‘ Coracia”’). See Journ. de Conchyl.. 1865, p. 385. —

Tue ZodLrocicaL Recorp, Vol. xxxix, 1902. Mollusca. By

KE. R. Sykes, B. A., assisted by E. A. Smith, I. S. O., pp. 85. The

total number of titles recorded is 611; this of course including many

papers purely palzontological. As in the preceding records compiled

by Mr. Sykes, the summaries relating to Anatomy and Distribution

are especially full, and cannot fail to be of the utmost utility to many

students. Thus, on p. 45, references to all articles dealing with

inland mollusks of the United States may be found. It may be well

to call attention here to a slip, whereby the species of Mew Mexico are

placed under ‘‘ Neotropical, Mexican Region,” p. 44, and omitted

from “American Region.” While New Mexico has a ‘‘ Lower

Austral”? element in Holospira, this genus has occurred only in a

few places in the extreme south, and the fauna as a whole is over-

whelmingly ‘‘nearctic.”” Again, Washington, Oregon and Bahamas

are put in the ‘‘ Transatlantic Province ”’ (p. 50), whereas the two

former should have been placed in the “ Californian,” and the latter

in the ‘Caribbean.”” The systematic part seems to be very well

done; though in treating the Pelecypoda, a further classification

would certainly facilitate reference. The several parts of the

Record may now be purchased separately, the Mollusca for 4, the

Brachiopoda 1 shilling.’ They will be found well worth the price,

even to the local naturalist, for the information on what is being

done the world over in the study of mollusks.

far enough to show the general quality of the work. The figures are

all bad copies, as well as most of the descriptions ; and such classifi-

cation as there is is only right by accident; such cases being readily

accountable for by the law of chances. If it were only a reasonably

careful compilation, the work might still have a certain value; but

it abounds with minor blunders, such as “ Chiton sowerbyanius”’ for

C. sowerbyanus, ‘‘ Port Jankson,”’ ‘‘ Chiton goodalii,” etc.; but per-

haps the most amusing case in the part just issued is that of Chiton

sulcatus Wood. This is renamed Chiton Woodii Cles., and said to

be from ‘‘ Lord Woods Insel der Gallopagos.” The new name is of

course quite unnecessary, because Ch. sulcatus Wood dates from

1814, some years prior to any other use of that specific name. The

new name Ohiton (Callochiton) Carpenteri Cles. (p. 64), is a syn-

onym of Callistochiton pulchellus Gray, besides being pre-occupied,

see-p. 25 of the same work. When the monograph on Scaphopoda

in the Conchylien Cabinet was issued, I thought that for blunders and

general inadequacy it could not be surpassed ; but the work on Chi-

tons, by the same author, promises to be a close second.—H. A. P.

In this further study of a Miocene land-shell fauna, Prof. Andrez

brings out several novelties of unusual interest. The new group

Gyralina contains Hyalinia (G.) roemeri n. sp., a form very similar

to our Helicodiscus lineatus. ‘There is a new species of Strobilops,

described under the name Strobilus. Also several. interesting. Heli-

ces. Adelopoma martensi n. sp., is a minute Diplommatina-like

form, in which relation is found with South American species de-

scribed under the genus Adelopoma of Doering, ranging from Argen-

tina to Guatemala. In this connection it may be well to call atten-

tion to the fact that forms of the same genus occur in eastern Asia.

** Diplommatina’’ pusilla Mart. of Japan, and its variety omdensis

Pils., which are placed by Kobelt (Tierreich, Cyclophoriden) in

Cylindropalaina, really have all the shell characters of Adelopoma.

Also D. amurensis Mouss. (Journ. de Conchyl., 1887), from Vladi-

vostock, which is apparently identical specifically with pusilla Mart.

Another German Miocene species, Diplommatina dietzi Flach, is re-

legumen, Solecurtus strigillatus and S. candidus. The former has

‘much in common with S. ensts, while as would be expected, Sole-

curtus differs in many respects. Respecting the true Solens, Mr.

Bloomer looks upon ‘ Solen vagina as a more primitive form, and

Ensis ensis and E. siligua as more specialized forms.”’ Cultellus

pellucidus coming somewhere between. He finds anatomical differ-

ences between Solen and Ensis, sufficient to call for the generic sep-

aration of the latter group, which until very recently has been con-

sidered a subgenus of Solen. These careful, comparative studies in

Pelecypod anatomy are valuable and worthy of imitation.

WOOL. VET, ~. OCTOBER, 1908. ce No. 6.

A NEW GENUS OF TROCHIDE.

“BY WILLIAM HEALEY DALL.

In dredging between Oahu and Molokai in the Hawaiian Islands,

in depths varying between 220 and 436 fathoms, sandy and rocky

bottom, the U. S. Fish Commission steamer ‘Albatross’ obtained a

number of specimens of a large deep-water gastropod shell, occupied

by hermit crabs and completely covered by the extended basal mem-

brane of a large Actinta. It is not uncommon to find gastropod

shells covered by sponges or hydroid zoophytes, commensal with a

Paguroid crab, and it often happens that the zoophyte grows beyond

_ the margin of the aperture forming a shield for the growing crab, to

their mutual advantage; since the crab im such cases does not have

to seek a new habitation on the ground that the old one has become

too small for him, while his movements prevent the zoophyte from

becoming smothered by the mud, as might happen if the crab sought

another domicile and left the old one lying on the bottom. In such

cases the lime of the original shell is often gradually absorbed, though

__ the Sponge or zoophyte retains more or less of the original form. In

Bthe present case, however, the original shell appears to be normally

so deficient in lime as to be practically of a flexible, horny consistency

and chiefly composed of a rather tough, thick layer of conchioline.

In order that it may retain its shape, it is necessary to keep it in

eeorol, as in the case of Torellia and some forms of Velutinide.

62 THE NAUTILUS.

STYLOBATES n. g.

Shell depressed-turbinate, few whorled, feebly calcified, with a

deep, funicular umbilicus bordered by a carina; surface wrinkled in

harmony with the incremental lines; aperture ample, interrupted by

the body whorl, the pillar lip straight, the outer lip and base continu-

ously arcuate; the suture appressed. Animal? operculum?

Stylobutes eneus N. sp.

Shell large, flexible, with three rapidly-enlarging whorls, which

are moderately convex above, descending to a well-marked but not

deep appressed suture; base convex, the margin of the umbilicus

carinate, its cavity straight-sided and funicular; last whorl expanded

at the aperture, which has a thin, simple margin, straight at the ter-

mination of the umbilical coil, slightly angular at the intersection of

the umbilical carina, the lips above separated for a short distance on

the body whorl; shell of yellowish-gray color (in alcohol) with a

well-marked, brassy lustre; sculpture of small, irregular wrinkles

harmonizing with the lines of growth; outer lip somewhat sinuous

and gently excavated at the periphery ; upper margin of the aperture

advancing beyond the lower. Maximum diameter about 75, mini-

mum 40, height 35, diameter of umbilicus about 10 mm.

Habit, station 3893 of the U.S. Fish Commission steamer ‘‘Alba-

tross,” in the Hawaiian Islands. There are occasional minute granu-

lations on the surface which may, however, be merely individual

peculiarities. The soft parts and operculum are as yet unknown.

This large and peculiar shell does not closely resemble any other

deep-water form yet recorded. While its proper classification must

remain unsettled until the soft parts are obtained, its general form

and habit recall several of the 7rochidz, and bear a curious super-

ficial resemblance to the New Zealand land shell formerly known ag

Felix (now Paryphanta) busby?.

DISTRIBUTION OF JAMAICAN SPECIES OF COLOBOSTYLUS.

BY P. W. JARVIS.

In this group there are thirteen clearly marked species :

Colobostylus interruptus (Lam.). C. nuttii Pils.

C. humphreyanus (Pfr.). C. albus (Sowerby).

THE NAUTILUS. 63

C. thysanoraphe (Sowerby). C. banksianus (Sowerby).

C. jayanus (Ads.). C. yallahensis (Ads.).

C. redtieldianus (Ads.). C. tectilabris (Ads.).

C. bronni ( Ads.). C. lamellosus (Ads.).

C. chevalieri (Ads.).

Colobostylus interruptus (Lam.) (Area No. 12). Living specimens

of this species are very rare, and only occasionally found on the Dal-

las mountains, but weather-beaten shells are very abundant on Long

and Dallas mountains, lying to the north of Kingston. In Mr. Henry

Vendrye’s list of Jamaican Land and Fresh- Water Shells, it is classed

under Choanopoma.

Colobostylus humphreyanus (Pfr.) (Area No. 4) inhabits a very

wide area, from the Cockpit country in St. Elizabeth and Trelawny,

westward to ‘Silver Spring,” in Westmoreland. The differences

between specimens from distant localities are very slight and there

seems to be no tendency to vary amongst individuals.

Colobostylus thysanoraphe (Sow.) (Area No. 6) occurs on the high ;

' mountains in the center of the island. Fairly abundant in the Cave

Valley district.

Colobostylus jayanus (Ads.) (Area No. 7) is common throughout

Manchester. This species is somewhat nearly allied to C. thysano-

raphe. 1 have not yet found either any intermediate varieties or

both species in one locality.

Colobostylus redfieldianus ( Ads.) (Area No. 5) occurs in the two

parishes of Westmoreland and Hanover. Varies considerably in size

and color.

Colobostylus bronni ( Ads.) (Area No. 1). The metropolis of this

shell is the highland parts of St. James and Trelawny where it

abounds, it is common in smaller numbers throughout these two

parishes.

Colobostylus chevalieri (Ads.). The typical form of this very pretty

shell occurs somewhere in the mountains near Montego Bay. I have

not yet found it. Dr. F. A. Sinclair, who has kindly given me speci-

mens, did not take note at the time of the exact locality. The varie-

ties album and virgatum of Adams, are found together at Green

Island in Hanover (Area No. 13).

THK NAUTILUS. 65

Colobostylus nuttit Pils. (Area No. 2), is found on the Coast moun-

tains at Braco, near Duncans.

Colobostylus albus (Sowerby) (Area No. 3). The typical forms of

this species inhabit the coast mountains from Port Maria to St. Anns

Bay and for a few miles inland. The var. fuscus of Adams, comes

from the John Crow hills in Portland (Area 14).

Colobostylus banksianus (Sowerby) (Area No. 7). This species

has its headquarters in Manchester and spreads for a considerable

distance across the borders of St. Elizabeth and through the Cockpit

country.

Colobostylus yallahensis (Ads.) (Area No. 9). The types of this

species came from ‘“‘ Roaches Gully,” on Creighton Hall Estate, in

St. Thomas; it is also found at one or two other places on the Yal-

lahs hills. This species also crops up at Schwallenburg (Area 9 A)

on the slopes of Mount Diablo, in St. Anns. Ido not know of its

having been found anywhere else than in these two small areas.

Colobostylus tectilabris (Ads.) (Area 10), inhabits the central and

southern parts of Manchester. It is widely distributed over this area

but not common.

Colobostylus lamellosus (Ads.) (Area No. 11) is found on the

mountains of the South Coast of St. Elizabeth.

A NEW JAMAICAN COLOBOSTYLUS.

BY HENRY A. PILSBRY.

Colobostylus nuttii n. sp.

Shell narrowly umbilicate, turbinate-conic, similar in general shape

to C. chevalieri (C. B. Ad.); surface very finely, densely and regularly

striate throughout, the striz more spaced and sharper on the early

whorls, exactly as in C. albus. Coloration various, but usually consist-

ing of a wide, purplish or purple-brown belt, leaving a pale or whitish

band below the suture and around the umbilicus; the penult. whorl

or whorl and a half bicolored, the lower part dark, the upper whitish ;

the upper whorl always purple-black. 3 to 34 very convex whorls

remain, the summit being truncate. ‘The aperture is vertical, chest-

nut-brown within, at least in large part, not quite circular, being a

little longer than wide, and with the inner margin less arcuate than

the outer. Peristome moderately broad, with a low, brown, raised

inner rim, and whitish or white expansion, which is dilated into a

slightly recurved or concave lobe above, adnate to the preceding

whorl ; it is also a little dilated at the columellar margin. The um-

bilicus is smooth within, but rarely shows faint traces of a few spiral

cords.

Length 17, diam. 13 mm.

Length 15, diam, 11 mm.

The operculum is white externally, slightly concave, rather coarsely

wrinkled. tangentially, and with about 24 whorls after the blackish

nucleus, which is situated at about the lower third, and much nearer

the columellar than the outer margin. The edge is very deeply

grooved, the sides of the groove smooth or nearly so.

Braco, Trelawny, in northwestern Jamaica, the types collected by

Mr. George Nutt, and sent by Mr. P. W. Jarvis.

This species differs from C. chevalieri in the sculpture of fine vertical

strie, the obsolescence of spiral cords around the umbilicus and in col-

oration. C. albus, which has similar sculpture and operculum, differs

in the narrow lip, not dilated above. The latter species is the most

nearly related form known to me. |

Sometimes the wide median color zone is split by a lighter per-

ipheral tract; or it may be reduced to a narrower belt below the

periphery.

NOTES ON THE MOLLUSK FAUNA OF SAN NICHOLAS ISLAND.

BY HERBERT N. LOWE.

San Nicholas, the most bleak and barren bit of land in the whole

group of the Santa Barbara Islands, lies apart from its more favored

sister islands, sixty-five miles from the mainland. It is a small

island, barely nine miles long, by four or five wide, without a vestige

of a tree of any kind, and very little of the cactus, which grows in

such quantities on the other islands. About half its area is a great

desert of shifting sands where lie the bleaching bones of an extinct

race of Indians which inhabited the island many years ago. Many

THE NAUTILUS. 67

strange and interesting implements of stone, bone and shell have

been found, showing very skillfull workmanship.

On this favored spot it was the writer’s good fortune to spend three

weeks in scientific research during the month of February, 1902.

The marine shells are all of rare occurrence, with the exception of

Acmea gigantea, Haliotis cracherodit and Mytilus californianus, which

grow on the rocks by the thousand. The red ‘abalone,’ Halzotis

rufescens, used to be very abundant on the island, as was also the

giant Cryptochiton steller’, but are now of very rare occurrence. The

smaller species, such as Ocinebra circumtexta, Marginella varia,

Gadinia reticulata, Mitromorpha filosa, Megatebennus bimaculatus and

a few of the smaller chitons were found under stones in little shel-

tered inlets away from the heavy surf.

The remainder of the coast line is composed alternately of great

ledges of smooth rocks and strips of smoother sand beach. Unlike

the other islands, with their steep cliffs jutting off abruptly into deep

water, San Nicholas is low, lying with bluffs sloping gradually to the

water’s edge, with shallow water a long distance from shore, A belt

of kelp, in places more than a mile wide, surrounds the island, mak-

ing a landing very difficult. A fair idea of the marine species in-

habiting the coast may be obtained from the bleached shells found on

the old Indian camp grounds, as they seemed to have eaten molluscs

of every description, principally the Halotis, fragments of which

cover the mounds by the million, and the irridescent shells reflecting

the rays of the sun in a gorgeous and dazzling play of color, present

a picture long to be remembered.

The following is a list of marine species found on the Indian

mounds:

Cyprza spadicea Gray. Cryptochiton stelleri Midd.

Trivia solandri Gray. Cardium quadrigenarium Con.

Erato vitelina Hds. Cardium biangulatum Sby.

Acmea gigantea Gray. Rupellaria lamellifera Con.

Cancellaria cooperit Gabb. Halotis corrugata Gray.

Ischnochiton conspicuus Cpr. Natica sp.

The reefs where the Acmzxa gigantea have their home, jutting out

between the sand beaches, are, after every storm, temporarily cov-.

ered over with sand. At such times a large quantity of sand gets

under the mantle of the Acmea, causing little nodules to be formed

on the inside of the shell, from the size of a pinhead to that of a small

bean. The shells were of unusual thickness, to withstand the con-

tinual pounding of the surf. —

As I have previously stated, the island is almost destitute of vege-

tation, making the land shells few and far between, The only species

were: Helix tryoni, found alive in small numbers; H. feralis, one

fresh specimen and occasional dead ones; H. sodalis, none but dead

and bleached ones. I should probably not have obtained any live

Helices had it not been for a rain storm which came on while I was

on the island, when the tiny creatures seemed to sprout as it were

from the bowels of the earth. After every rain storm there comes a

fierce, drying, west wind, which makes the snails “ hunt their holes”

in a hurry, and any unfortunate Helix not under cover is made short

work of by the scorching winds and sand blowing upon them. About

the only food for the snails is a low-growing salt bush, at the roots of

which they burrow in the dry season. At the east end of the island’

are found the few scattering live Helices with comparatively few dead

shells, while at the west end of the island the dead and bleached

shells lie by the thousand on the great stretches of shifting white

sand. As there is no vegetation whatever at that end of the island,

and the prevailing winds, in the opposite direction, makes it impos-.

sible for them to have been driven there. by that agency, it remains’

an unanswered question how came these myriads of dead and'

bleached shells in this sand desert ?

At the west end occasional springs of fresh water drip from over-

THE NAUTILUS. 69

hanging ledges of rock to little pools on the sand beach, and then

flow to the great ocean without having benefited the island in any

way. In these little pools a few small stunted Physas were found.

During the winter season the island is the rendezvous of Japanese

fishermen, who catch lobsters for the Los Angeles market. They

also make a business of hunting abalones at low tide. The meats are

cleaned from the shells, boiled in salt water and spread on the flat

rocks to dry, when they are sacked up and shipped to Japan and

China, and considered a great delicacy by the celestial epicures,

The shells are sent to Los Angeles and made into pearl buttons,

souvenir spoons and various “‘ curios”’ to tempt the pocket-book of

the tourist. |

MISS S. F. PRICE.

We learn with deep regret of the death, at her home at Bowling

Green, Ky., on July 3d, of: Miss Sadie F. Price. Miss Price was

born at Bowling Green. Her parents were Alexander M. and Marie

Price. For many years Miss Price had been actively interested in

the flora of her State, upon which she published a number of articles,

among them a useful illustrated work, ‘* The Fern Collector’s Hand-

book.” Ornithology also claimed her attention, and in the last

dozen years she became interested in mollusks, and becoming ac-

quainted by correspondence with conchologists working upon inland

‘species, she collected assiduously and successfully, publishing a list of

her local collections in this journal for November, 1900. Miss Price

assisted upon the Kentucky exhibit at the Columbian Exposition,

where she exhibited plants and a series of paintings of the birds of

Kentucky, which attracted much attention. Like a true naturalist,

Miss Price passed on to many pupils the love of nature. She is sur-

vived by her sister, Miss Mary Price, with whom she had lived for

many years.

SOME NOTES ON THE GENUS FULGUR.

BY CHAS. W. JOHNSON.

In the very interesting and valuable paper, ‘“‘ Studies of Gastro-

poda II, Fulgur and Sycotypus,” by Amadeus W. Grabau (Amer.

Naturalist, August, 1903), the author has again brought to generic

rank the name of Sycotypus. No stronger evidence is brought forth

to uphold this view than that already given, viz., the character of the

protoconch, as pointed out by Conrad. Dr. Dall and others consider

the condition of Conrad’s specimens to have been pathologic, while

‘the many tertiary forms seem to completely bridge all distinguishing

conchological characters, leaving only the ciliated periostratum, a

feature which is lost in the fossils and in Fulgur pyrum is often obso-

lete or wanting. Still Sycotypus, as a rule, forms a recognizable

group, very convenient in tracing the origin of many of the species.

Has the protoconch of /. pyrum been studied? It may have no

bearing on the subject, but it is interesting to note that while the

egg-capsules of F. canaliculatum are readily distinguished from

carica and F. perversum by having a single-keeled edge, those of /.

pyrum are biangular, resembling those of F. perversum in miniature.

In tracing the ancestral relations of the various so-called species,

Mr. Grabau has brought out many points which deserve careful con-

sideration. Every one who has made a study of the tertiary species

probably has'a different view in regard to the relationship of the

various forms, and these views should be freely given and the con-

sensus of opinion adopted.

All” agree that the Eocene Levifusus is probably the immediate

74 ; THE NAUTILUS.

ancestor of Fulgur, the latter being first represented in the Oligocene

and Lower Miocene by F. spiniger and its several varieties, and in

the middle Miocene by /. fusiformis.*

From this form was probably derived, as Mr. Grabau states, ‘ the

large and ponderous Fulgur maximum Conr.,” which apparently,

through the varieties trztonis and filosum,’ leads to the recent J. carica

and its variety eliceans. On the other hand, the sinistral form un-

doubtedly evolved from J. maximum in the upper Miocene much

earlier than Mr. Grabau’s table would imply, and by forms such as

fF. adversarium and F. obfilosum leads directly to the recent F. perver-

sum, and its rare variety Avenert: Phil. presenting exact parallels to

the J. triton?s filosum and F. carica eliceans series, thus strengthening

the theory of a common ancestry. During the Pliocene, F. perver-

sum seems to have extended and found more favorable conditions

further south, for it is really more plentiful and better developed in

the Caloosahatchie than in the Waccamaw beds. On the gulf coast

at the present time it is more abundant than on the Atlantic, while

Ff. carica is not found at all in the Gulf of Mexico.

In the Caloosahatchie beds there appeared a new form, F. rapum

[eilp., probably derived from F#. perversum (as such forms of perver-

sum as Mr. Grabau has called obrapum would indicate) and appar-

ently representing a reversion to the maximum type.

T would not consider obrapum to be sinistral rupum, neither would

I consider obfi/osum to be a sinistral filosum; for while admitting a

common ancestry, the immutability of the recent perrersum and

earica has given us reason to believe that the same stability has ex-

isted since they originated. To admit the mutability of sinistral and

dextral forms only makes ‘ confusion worse confounded.” FF. rapum,

through the form tritonotdes Grabau, leads to the recent F. coarcta-

tum Sowerby of the Gulf of Mexico, an extremely rare shell which

may possibly be extinct. The long anterior canal of the monstrosity

F. candelabrum Lam., as figured by Kiener, indicates a position here,

rather than under eliceans.

1TIn a bed which overlies the Chipola and having an out-crop in a mill-race

two miles east of Argyle, Fla., I found this species, identical with specimens

from St. Mary’s, Md.

2 F. filosum did not originate in the upper Miocene, as indicated by Mr. Gra-

bau’s table; F. maximum, tritonis and filosum are all associated with F. incile at

Yorktown, which moreover is the type locality for filosum.

THE NAUTILUS. 13

The Sycotypus group probably originated, as Mr. Grabau suggests,

with such forms as £. burnsii, perizonatwm and tampaensis in the

Upper Oligocene (Lower Miocene?) and F. coronatum and rugosum

in the Middle Miocene. It seems rather a doubtful conclusion to

refer to F. rugosum as the direct ancestor of /. canaliculutum. I

have not seen the * Faison variety ” of /. canaliferum referred to,

but I am inclined to consider £. alveatus and incile as intermediate

forms and to trace the line of ancestry of /. canaliculatum and pyrum

through the same formations in which I trace / carica and perver-

sum, viz., the Miocene of Virginia and North Carolina and the Plio-

cene of the Waccamaw and Caloosahatchie.

The typical /. eneile of Yorktown seems to have evolved into two

forms in the Duplin county beds; the one, &. conradii' Tuomey and

Holmes, leads to the so-called canuliferum Conr., the type of which

is the F. canaliculatum T. & H., from the Waccamau, and in no way

separable from the recent form. The other form, derived from dnez/e,

represents a very mutable species, and to the various forms had been

applied the names of /. carolinens/s, excavatus, elongatus and pyri-

formis. ‘These exhibit, however, all gradations and extend through

the Pliocene to the recent F. pyrum Dillw.

F. concinnum does not belong to the ** Middle Miocene.” The

type locality is Sampson Co., N. C., and I found it also along the

Cape Fear River, ten miles above Elizabethtown, Bladen Co., in a

bed typically Duplin. I do not know the forms which Conrad de-

‘scribed as amenum and Kerrti and a study of the form from Walker’s

Bluff, N. C., might throw additional light on the subject.

THE GREATEST AMERICAN PLANORBIS.

BY HNENRY A. PILSBRY.

Planorbis magnificus n. sp.

The shell is very large and high, sinistral as usual, the upper or

spire half yellow or pale brown, the lower or umbilical half dark

brown. Surface glossy, finely marked with growth-lines, and usually

some spiral series of minute long granules, as in many species of pond

culatum is clearly shown by a series in the Joseph Willcox collection of Ful-

gurs, presented to the Academy of Natural Sciences, Philadelphia.

snails (but without thread-like stria such as Planorbis trivolvis has).

Spire narrow, decply sunken, with steep sides; the summit of the

whorls acutely angular. Umbilicus deeply funnel shaped, the base

of the whorls so narrowly rounded as to appear almost angular.

Whorls nearly 5, the last very large, rounded at the periphery, some-

what flattened and sloping above, more convex below it. Aperture

but slightly oblique, irregularly ovate, angular or subangular above,

broadly rounded below, the peristome slightly expanded.

Diam. 86, height 24.5 mm.

Lower Cape Fear River in the vicinity of Wilmington, North

Carolina, collected by Mr. Wm. P. Seal.

This species is remarkable not more for its size than for the great

width, far exceeding any other species. It differs from P. trivolvis,

ammon and their allies in the surface sculpture and narrower umbili-

cus. LPlanorbis corpulentus Say is also. somewhat related, but its

differential features will be obvious in a comparison with Mr. Bryant

Walker’s illustrations and description of that species, ee

OBSERVATIONS ON THE BYSSUS OF UNIONIDE.:

BY L. S. FRIERSON.

Recently, while collecting young or very small Untonide, two’

species were obtained having a byssus. “Seven or eight specimens of

Lampsilis tecusensis Lea, were taken so provided, and one specimen

of Lampsilis fallaciosus Simpson. The ZL. terasensts varied from

one-eighth to one-half inch in length, while the LZ. fallaciosus was

five-eightlis of an inch long.

The size of the shell and the length of the byssus did not appear

to bear any constant ratio, nor did the size (or diameter) of the

byssus vary. ‘The most of the texasensis and also the fallaciosus were

taken by means of a combination flour scoop and sieve such ais is

used in our kitchens. ‘This was used to scrape up the bottom, and

then the mud washed out leaving the larger stuff behind.’ In ‘this

way the original position occupied by the shells could not be ascer-

tained; but several specimens were taken attached to sticks, and

these were hanging suspended in the water,clear of the bottom.’

THE NAUTILUS. 77

The byssus was attached to the soft parts at about one-fourth dis-

tance from the anterior to the posterior end.

One of the texasensis had a byssus cylindrical in shape, about half

the diameter of a human hair laid alongside for comparison. But

that of the others and also of the fallaciosus was roughly ribbon-

shaped, and resembled a flat piece of ‘* molasses pulled-candy,” both

in texture and in contour. While wet they were very elastic, but

exceedingly brittle when dry, appearing to be of the same composi-

tion as the ligament of the shell. These ribbons were irregularly

twisted, now to the right, now to the left, as well as vertically undu-

latory. This gave them a sort of spiral spring effect which was

quite noticeable.

The proximal end, when separated from the soft parts by slight

traction, was bulb-shaped and attached to a style-like process which

occasionally could be drawn from between the valves. My appli-

ances were not equal to the task of determining whether this process

was an outgrowth of the foot or of the mantle. The distal ends were

attached to quite a little raft of heterogeneous material, and I believe

that this ‘“‘ raft” serves to make a float, analogous to the balloons by

which spiders sail through the air in the autumn months. None of

them seemed to be directly fastened to any large body such as sticks

or old shells, but merely entangled with the moss or alge growing on

the sticks, ete. The lengths of these byssi were about three to

eight inches.

Several very small Quadrulas were taken. But no byssus was

noted on any of them. Could this feature be a characteristic of

Lampsilis and closely allied genera?

ber of this journal, this was listed as G. gundlachi.. Mr. Geo. H.

Clapp, who obtained some of Rhoads’ specimens, directed my atten- °

to its distinctness. G. gundlachi occurs at a’ neighboring locality,

Lemon City, Fla., as well as throughout the St. John’s valley, and

in west Florida—probably extending all over the peninsula, It was

collected by Mr. Singley at Hidalgo, Texas, and .is.a well-known

West Indian and Mexican species. G. gundlachi is invariably

characterized by the presence of a sculpture of very minute regular

and close, spiral striz, as mentioned in the descriptions of Pfeiffer,

von Martens and others, and as I have confirmed in numerous speci-

mens from Florida, Texas, Mexico and the West Indies.

3 mm.

Amagisan, Izu. Type no. 85753 A. N.S. P., from no. 1140 of

Mr. Hirase’s collection.

This is one of the finest of the japonica group of species, resemb-

ling G. jacobit in contour, but much larger, with a comparatively

wider umbilicus and darker in color. It is named in honor of Dr.

QO. von Moellendorff, in whose untimely death malacology has lost

one of the most acute and industrious authorities upon Oriental snails.

Pristiloma japonica n. sp.

Shell minute, imperforate, discoidal, the upper surface very low,

conoidal, base convex, periphery rounded; pale yellow, somewhat

translucent, glossy and almost smooth, very faintly striate radially

above. Whorls 54, slowly widening, slightly convex, the base im-

pressed in the center, Aperture nearly vertical, narrowly lunate,

the outer lip acute and thin, strengthened a short distance within by

a white, callous ridge, showing as a buff streak outside; columellar

margin narrowly reflexed at the insertion. Alt. 1.5, diam. 2.7 mm.

Toya, Kuziro, in eastern Yesso. Types no. 85754 A. N.S. P.,

from no. 1146 of Mr. Hirase’s collection.

It is impossible to say whether this is really a Prist‘loma until the

jaw and teeth can be examined; but from the close resemblance of

the shell to P. lansingi, the generic reference seems probable. There

is no Oriental group to which it could properly be ALES to my

knowledge. It is a new generic type for Japan.

gan, sent by Mr. Bryant Walker. :

This species is different and distinct from all our Pisidia. It

somewhat resembles P. ultramontanum Pr., but is much smaller, its

beaks are narrower, of different shape and more prominent, Some

of the specimens from the creek are higher over the beaks and in the

posterior part, and thus the mussel is of a rather different Sheps In

others, the beaks are less flattened, laterally.

Pis. rowelli n. sp. Mussel well inflated, elliptical-ovate in outline,

angles at scutum and scutellum slightly projecting, broadly rounded ;

posterior margin just perceptibly subtruncate, supero-anterior slope

slightly marked; beaks a little posterior (‘in normal position ”),

large, rounded, projecting over the hinge margin; surface shining,

slightly and irregularly striate, with a few coarser lines of growth ;

horn colored to brownish over the beaks, usually with a lighter zone

along the margins, not sharply defined; shell translucent, rather

thin; hinge slight, plate rather narrow ; right cardinal tooth angular,

with its posterior part thicker and grooved, left anterior short, tri-

angular, placed high up on the plate, the posterior much longer,

oblique, curved; lateral teeth with rather short, abrupt cusps in the

left valve ; the outer ones in the right valve small ; ligament slight.

- This largeand beautiful Pisidium cannot be mistaken for any other

species. It seems to be related to abditum Hald., and some of the

old-world Pisidia. Young specimens are very little inflated, and

of a light, almost whitish color.

- Pis. cuneiforme n. sp. Mussel inequipartite, oblique, moderately

to rather well inflated, mostly so near the beaks; hinge margin

slightly curved, the angles at the scutum and scutellum projecting ;

anterior part considerably longer, attenuated, somewhat cuneiform,

and directed downward. the end rounded, supero-anterior slope well

marked, straight or slightly curved; posterior part short, subtruncate ;

beaks moderately large and slightly elevated over the hinge margin ;

surface finely and irregularly striate, pale to yellowish horn-colored,

or whitish, dull to shining; shell opaque to subtranslueent, thin ;

hinge slight, short, plate narrow ; cardinal teeth placed far towards

the anterior, well formed ; the right curved, its posterior part slightly

thicker and grooved; the left anterior well curved, the posterior

slightly so, almost longitudinal and above the anterior, long; right

lateral teeth slight, cusps low and rounded, the outer ones well

formed ; in the left valve the cusps are short, high, abrupt, pointed ;

ligament slight.

' Habitat: Michigan and Minnesota. In Michigan: Byer’s trout

pond, Kent Co.; Blue Lake and Green Creek, Muskegon Co.; Hess

Lake, Newaygo Co.; Lake Michigan, at High Id. Harbor. Clear-

water River, Stearns Co., Minn. Collected by Messrs. Bryant

Walker, H. E. Sargent and R. G. Kirkland.

Specimens were received in 1895, and again in ’98 and 799, and

then regarded as representing a distinct species. Yet the number of

‘specimens from each place being limited, it seemed advisable to wait

for more materials.

Pis. cuneiforme has some resemblance with P. subtruncatum Malm.

and (var.) euneatum Blz., of Europe ; but the beaks are broader, less

elevated; the surface striation and appearance are different, and the

young of both show more differences between each other than the

adult. Of our North American species, it has resemblance only with

some forms of P. compressum, but our species is much smaller and

its anterior part is longer, comparatively. Young and half-grown

specimens are comparatively shorter, less inequipartite and less ob-

lique. i

82 THE NAUTILUS.

A well-marked feature of the hinge is, as it seems, the relative

position of the teeth, the distance between the cardinals and posterior

lateral cusps being twice as long as that between the cardinals and

anterior laterals. In other species, e..g., Pis. compressum, variabile,

noveboracense, that difference is much less marked, and in P. vir-

ginicum the cardinals are about equidistant from the laterals.

This shell, received by MM. Sowerby and Fulton as #. clansom-

a species of smaller size that one of these gentlemen sent me some

years agoas Lf. Farrisit Higg., or rather #. Higginsi Pfr., the former

name being preoccupied. However it does not seem to correspond

with the original diagnosis. The present species is larger, its sur-

face is rough but of a plain brown color, ornamented with a brown

band and the umbilicus is nearly closed.

Epiphragmophora Turtoni Anc.

This I have described in the journal as probably Bolivian, but

subsequently my friend Mr. Gude has described from Paraguay an

J. Dormeri, which appears to be very close to it and of whieh I have

seen the type in his collection. Both are probably from the same

We regret to chronicle the death of Mrs. Henrietta H. T. Wolcott,

of Dedham, Mass., following a severe accident. She passed away

after mucb suffering, October 8th, in the 78th year of her age. Mrs.

Wolcott was deeply interested in the study of nature, was a proficient

botanist, and of late years interested in Conchology. A wide traveler,

she was never happier than when engaged in gathering interesting

material suitable for educational purposes; and many small, well-

84 THE NAUTILUS.

chosen school collections were given by her to educational institu-

tions and public schools. In the course of her travels she frequently

obtained new or rare specimens which she shared with cordial pleas-

ure with those students to whom they were of special interest. Her

last contribution of this kind was the Sonorella Wolcottiana from

Palm Springs, in the desert region of southeastern California. Phil-

anthropic work also claimed much of her attention, to which she

brought a mind clear and sensible, broadened by experience of many

years at home and in distant countries. Mrs. Wolcott was the

daugher of Joseph and Eleanor Eustis, of Boston, and the widow of

the late Jolin W. Wolcott. She leaves a son and two daughters, be-

sides many, not bound by ties of relationship, yet who will remember

her as a friend, benefactor, or co-laborer.—W. H. D.

A NEW CALIFORNIAN TRIVIA.

BY WILLIAM J. RAYMOND.

During the summer of 1901 the University of California, with the

financial aid of friends in Los Angeles, maintained a Marine Bio-

logical Laboratory at San Pedro, California, and carried on biolog-

ical exploration along the coast from Redondo to Newport, around

Catalina Island, and from Los Coronados Islands to La Jolla in the

vicinity of San Diego. The large gasoline launch “ Elsie’? was

chartered for the summer and equipped with apparatus for the study

of the physical environment of marine life, including depth, temper-

ature and salinity of water and character of bottom. Collections of

specimens were made within the regions named, from shore-line to

an extreme depth of 100 fathoms. For this purpose the launch was

provided with a winch and rope, dredges, trawls, tow-nets and re-

ceptacles for the preservation of the specimens. The molluscan col-

lections, which were large and interesting, were placed in the writer’s

hands for identification and report. In advance of a complete report

it is desirable to put certain observations on record, among them the

descriptions of new species encountered. <A previously known but

undescribed species of Z77rivia is: |

Trivia ritteri n. sp. Shell small, white, form ovate, inflated,

anterior extremity slightly produced, spire completely covered, but

rather prominent, base convex, outer lip margined, strongly sculp-

tured with about twenty, smooth, sharp ribs, much narrower than the

interspaces which are nearly flat and scarcely roughened by irregular

ruge parallel to the axis of tle shell, no sulcus, the ribs continuing -

86 THE NAUTILUS.

unchanged in width across the back, except that occasionally a few

ribs near the spire are interrupted at the median line; a few short

intercalary ribs are usually present on the sides of the shell ; aperture

rather wide, armed with 17 to 18 denticulations on the outer lip,

and 14to 16 onthe inner. ‘Two extreme specimens in size measure :

length 11.5, breadth 8.6, height 7.2 mm.; length 9.2, breadth, 6.5.

height 5.7 mm.

Catalina Island, 60 fathoms (Cooper) ; Monterey (Dall) ; Cortez

Bank, 54 fathoms (Dall); Catalina Island near Avalon, 40 fathoms

(Sta. 21, U. C. M. B. L.); off San Pedro, about 50 fathoms (Sta.

So, U:. CG. Mo By L.). }

A dead specimen and a fragment of a second, collected more than

thirty years ago by Dr. Cooper, as cited above, but wrongly identi-

fied as Trivia sanguinea Gray, are now in the museum of the Uni-

versity of California. Ifthe admission of 7. sanguinea to the Cali-

fornian fauna rests solely upon this identification, the name should

be removed from our lists. See Cooper’s Geographical Catalogue of

the Mollusca Found West of the Rocky Mountains, 1867, No. 626.

To Dr. Dall is owing the citation of localities which considerably

extend the known range of JT. ritter?. A specimen was submitted by

Dr. Dall to Mr. J. Cosmo Melvill, of Manchester, England, who

considered it new after comparison with 7. mudtilirata, europea,

candidula, pellucidula, etc. In the character of the ribs it somewhat

resembles 7. buttont Melv., but differs in color, being white instead

of straw-colored, in having about twenty instead of fourteen ribs, and

in its size, the latter species being 5.5 mm. in length. 7. ritteri

differs from 7. europea in the ribs, which in the former species are

less numerous, sharp, and much narrower than the interspaces, while

in the latter they are more rounded and wider. The shell of the

latter is also more inflated. From T. panamensis Dall, the present

species differs in much greater size and more uumerous ribs. It

gives me great pleasure to dedicate this beautiful species to Professor

William E. Ritter, in charge of the University of California Marine

Biological Laboratory at San Pedro, 1901.

ANNIE M. LAW.

For much of our knowledge of the mollusk fauna of east Tennes-

see and western North Carolina we are indebted to two ladies, Miss

ae a ee oe ee ee Ce ee Se a

TIIE NAUTILUS. 87

Annie M. Law and Mrs. GeorGe ANnprReEws. Before them,

RuGev had made a beginning in this beautiful but difficult mountain

country. Until Ferriss and his friends began their explorations,

these three enthusiasts were the only naturalists to exploit the region

for land mollusks.

Miss Law’ came from distinguished English ancestry. Her par-

ents were John and Ann Law, of Carlisle, England. Her uncle,

Richard Law, was governor of Malta. Other relatives who rendered

services to the State were Chief Justice Lord Ellenborough, the

Bishop of Bath and others. The Law family records were destroyed

during the Civil War, so that the exact date of Miss Law’s birth

cannot be ascertained; but her father, John Law, came to America

about 1850, Miss Law being about nine years old at that time.

‘* Mr. Law located some nine miles from the town of Maryville,

Blount county, Tenn., a wild, mountainous country, though there

was a watering-place about two miles distant where the elite of the

South came through the summer for health and rest. Otherwise our

neighbors were illiterate. There were no schools or churches, so that

our parents were our teachers and companions. My father died in

1852 or 703. During his lifetime on the farm, my sister would ride

into Maryville and recite Latin and algebra to Dr. Anderson (the

founder of Maryville Theological Seminary) once or twice a week.

Then moving into the town, she still continued these studies. She

passed the examination for teaching school, and received a certificate

at the age of thirteen. Being large for her age, she was given a

school. She was proficient in music and gave lessons.

* Through Col. W. G. McAdoo, of Knoxville, she was introduced

to Dr. James Lewis, of Mohawk, N. Y., who wished her to collect

shells. She had from childhood a taste for shells, mineralogy, ento-

mology, botany, in fact everything connected with nature. She

began a correspondence with Dr. Lewis about 1868, which continued

until his death. She had also a number of other correspondents in

America and abroad.

‘I might write a long story about some of her trips while colleeting.

After being in California four years, she returned to Tennessee and

spent several months there. On one occasion, Dr. Lewis wished some

particular shell from Bald Mountain in the Great Smoky Mountains.

She procured a young man friend and two horses, and setting out

from Concord, Knox county, went to the top of the Big Bald and

procured the shells desired. They had to spend the night there.

During the night there was a terrific thunder-storm far beneath

them. She never enjoyed a trip more. Another trip she made in

Monroe county was from Jalapa to Telico Plains. The distance was

not great, but it was a bitter cold morning, the banks of the river

covered with ice. She wore rubber boots, and wading in, got beyond

her depth; but she got the shells. On this trip, I was her com-

panion. As there was no house on the side I was on, I followed with

bare feet. She suffered very much, not having dry footwear; but

we soon reached a comfortable fire at a friend’s, dried our things and

were made comfortable. My sister never seemed to think of her own

comfort when engaged in the search for shells. Many such exposed

trips she made, the effects of which I think undermined her health.

‘¢When she returned to California the second time, I was with

her. We came by way of Mohawk, N. Y., visited the family of

Dr. Lewis, and had the pleasure of seeing his collection. We also

made a flying trip to Florida, visiting Jacksonville, St. Augustine,

Palatka and Silver Springs. Wherever we were, she collected shells.”

In California, Miss Law made her home at Watsonville, Santa

Cruz county, with her sister, Mrs. Andrews, until ber death, January

12, 1889.

Among the species discovered by her are Gastrodonta acerra, Vit-

rinizonites latissimus, Polygyra chithoweensis and P. lawt.

NOTE ON MUREX MARCOENSIS SOWERBY.

BY FRANK COLLINS BAKER.

In the Jonrnal of Malacology, volume 7, p. 162, Mr. G. B. Sow-

erby has described a Murex marcoensis from Marco, Florida. This

form was previously noted by Dr. W. H. Dall and the writer of this

note, it being considered by them a color variety of Murex mes-

sorius Sowerby. Dr. Dall, in speaking of Murex messorius says

(Bull. Mus. Comp. Zool., v. 18, p. 196), ‘‘ The Florida specimens

are often of a deep rose-pink.”” In Trans. Acad. Sciences, St.

——

THE NAUTILUS. 89

Louis, the writer remarked on p. 377, ‘* Dr. W. H. Dall bas char-

acterized a variety rubidum, from Cedar Keys, Florida, the shell

being of a deep pink color.’”’ The writer was in error in stating

that Dr. Dall had characterized the variety rubidum, he having

- simply referred to the rose color.

The history of this variety will therefore stand as follows :

1889. Dall: Murex messorius (Sowb.) Reeve, pink variety, Bull.

Mus. Comp. Zool., v. 18, p. 196.

1897. Baker: Murex messorius (Sowb.) Reeve, var. rubidum

“« Dall,” Trans. Acad. Sci., St. Louis, v. 7, p. 377.

1900. Sowerby: Murex marcoensis, Journ. of Malocology, v. 7,

p- 162. .

If the two forms are the same, which I have no reason to doubt,

it will stand as Murex: messorius var. rubidum Baker.

whorls one and one-half, not enlarged, dextral, translucent, shining,

without sculpture. Post-nepionic whorls two, decidedly inflated,

with the slit about half way between the suture and the periphery,

open only in about one-twelfth of the last turn, marked on the rest

as a narrow, moderately deep, depressed groove, which is bounded

on each side by a raised thread. The remaining ornamentation of

the whorls consists of feeble, raised, equally-spaced, axial riblets,

which follow the curve of the outer lip. These riblets are best de-

veloped between the suture of the whorls and the slit, becoming en-

feebled toward the periphery and quite obsolete on the base. In

addition to these, a few ill-defined spiral lirations manifest themselves

under high magnification between the suture and the slit. Suture

strongly impressed. Periphery of the Jast whorl well rounded. Base

rather depressed and somewhat concave toward. the umbilical region,

marked by the faint continuation of the axial riblets and many ex-

ceedingly fine spiral striz. Umbilicus narrow, deep, bounded by a

weak basal fasciole. Aperture large, broadly pyriform with continu-

ous peritreme, posterior angle obtuse, somewhat patulous anteriorly ;

outer lip thin; columella oblique, thin: parietal wall distinct, re-

flected upon the body whorl, partly closing the umbilicus.

The type is in the U.S. Nat. Museum collection, No. 171400, and

comes from the Gulf of St. George, Patagonia. It measures, long.

0.8 mm., diam. 1.4 mm.

GENERAL NOTES.

Vicrtna Depositing Eaes.—You may be interested to know

that on November 8th, and again to-day (November 15th), I found

Vitrina limpida Gld., depositing their eggs. The eggs are white,

almost round, some of them being slightly pointed at one end, and

about 1 mm. in diameter. They are laid in bunches of six or eight,

under rotting wood on the ground.

In the ten years during which I have been watching this ‘* colony,”

I have never seen a young shell, but think the eggs are hatched in

the early spring, the snails reaching maturity in the autumn. From

October to January is their active season, and during those three

months they can be found moving around on any pleasant day. Have

found them very active when the temperature was below 40°.—GkEo.

PUBLICATIONS RECEIVED.

MOoLiusks OF Our SOuTHEASTERN Coast.—The United States

National Museum has recently published a reprint of its Bulletin No.

37: ‘A preliminary catalogue of the shell-bearing marine mollusks

and brachiopods of the southeastern coast of the United States, with

illustrations of many of the species,” by William Healey Dall. The

first edition of this work, published in 1889, having become exhausted,

the reprint has been found advisable to meet the requests for copies.

The body of the reprint is a verbatim copy of the earlier edition,

but the usefulness of the work has been much increased by the addi-

tion of 21 new plates, containing 188 figures.

It is a classified list of the shell-bearing marine mollusks found

between Cape Hatteras and Mexico. For each species the author

has indicated the extreme northern and southern range, and some of

the more important intermediate localities ; the range in depth; the

range in time, and its occurrence in Europe, if it be known to occur

there. The average length of specimens of part of the species is

given. 95 plates, containing many hundreds of excellent figures,

illustrate a great many of the species. The reprint is obtainable by

those properly entitled to receive it.—W. B. M.

List oF British Non-MARINE Morttusca.—By B. B. Wood

ward (Journal of Conchology, x, pp. 3852-867, Oct. 1, 1903).

British conchologists have been among the most conservative in

matters of nomenclature and taxonomy. For many years it seemed

that no material innovation from the arrangement in Jeffrey’s Brit-

ish Conchology could obtain recognition in the non-marine mollusks

of the tight little isle. In the last few years all this has been

changed. The great progress of malacological svience abroad and

the revival at home, signalized by the formation of the liveliest

Malacological Society in the world, has finally lead to the revision of

the British list now before us. The general classification followed is

that of Fischer, but greatly modified in details of family and generic

divisions. A few points of especial interest to American concholo-

gists may be mentioned here. The name Vitrea radiatula is pre-

ferred to that of V. hammon7s. Mr. Woodward concludes that.

‘‘there is a costate form of Vallonia in America distinct from the

THE NAUTILUS. Id

costate variety of V. pulchella present in Britain, and I recommend

that until it can be demonstrated more conclusively than has at

present been done that there are two British species, the costate form

be classed as a variety of the typical V. pulchella.”” The name

_ Tachea being preoccupied for a genus of birds, Cepea Held is substi-

tuted. The nomenclature of ‘* Buliminus”’ is discussed, and that

name is replaced by Hina of Leach, and the family name is changed

to Enid. Pupa is discussed at iength. It appears that that name

was first used for species of Acteon and Cerion, and finally by

Drapernaud for what is now known as Pupa. Mr. Woodward con-

cludes that Jaminia Risso, 1826, is the earliest available name for

the Pupa muscorum group.

In the Basommatophora, Phytia myosotis replaces the familiar

Alexia, preoccupied in Coleoptera, and Ovatella takes the place of

Leuconia, being earlier. Planorbis glaber J-ffr. is definitely sep-

arated from the American P. parvus. Mr. Woodward disputes the

propriety of Dall’s course in substituting Corneocyclas for Pistdium,

but otherwise the generic nomenclature of bivalves calls for no

special comment.

Mr. Woodward uses the emended forms “ Dreissensia,”’ ‘* Vivipara,”’

‘« Aplecta”’ and ‘** Assemania,”’ a course against the general usage

in this country. —H. A. Pitspry. .

On Some Moctuusca Known To Ocour In [npd1IANA.—By W.S.

Blatchley and L. E. Daniels (27 Ann. Rep. Dept. Geology and Nat.

Resources of Indiana for 1902). This paper of 100 pp. is supple-

mental to the report on Indiana mollusks by Dr. R. BE. Call, pub-

lished in 1899. Some 92 species are added to the fauna of the

State, a large number of them being figured and all described. Some

little known or new forms are among those illustrated, such as

Succinea calumetensis Calkins, Limnea woodruffi Baker, Ancylus

shimekii Pils., Lithasia obovata biconica and Goniobasis indianensis

Pils., various Pistdia described recently by Sterki, Lampsilis

blatchleyi Daniels, etc., so that the report is of general interest to

those studying our inland mollusks.

CONTRIBUTIONS TO THE TERTIARY FAuNA OF FLORIDA.—By

Wm. H. Dall. Trans. Wagner Free Institute of Science, Philadel-

phia, vol. ili, pt. vi. :

This constitutes the concluding part of Dr. Dall’s extensive work.

The entire volume (iii) comprising 1654 pages and 60 plates, consti-

tuting the most valuable and exhaustive treatise on the American

Tertiary fauna ever presented, and forming a work indispensable

both to the conchologist and palxontologist.

Parts I and II are devoted to the Gastropoda, and the remaining

parts to the Pelecypods, Part III being given up entirely to a new

classification of the latter. All the parts as they have appeared have

been reviewed in the pages of Tue NauriILus.

The present work takes up the family Venerida, with a history of

the various generic names employed; most of the changes in nomen-

clature have, however, been noted in the ‘* Synopsis of the Veneride’”’

(Proc. U. S. Nat. Mus., xxvi, 335), but this work in many cases

covers the ground more thoroughly, giving the complete generic and

specific synonomy of many of the recent forms which extend into the

tertiary. 41 new species are described.

In the family Luc*nide there are 33 new species, and in the

Chamidz seven. The subgenus Hehinochama Fischer is given gen-

eric rank. The family Carditide is also well represented in the ter-

tiary, 18 new species being described. The Cyrenide contains sev-

eral new forms, the section Cyrenodonax Dall., the type of which, C.

formosana Dall, n. sp., “ Recent in Formosa, at the mouth of the

Tamsui River,’ is described in a foot-note. Modontopsis is proposed

for Miodon Sandberger 1870, not of Carpenter, 1865. /geria Roissy

is adopted in place of Galatea Brug. (Galathea Lam.) 1803, not

Fabr. 1793. Type G. radiata Lam.

In regard to the smal] fresh-water forms usually referred to the

Cyrenida, Dr. Dall says: ‘‘ While closely related, it seems more

convenient to place Sphaerium and Corneocyclas (= Pisidium Pfeif-

fer) in a separate family,” Sphaeriide.

Orassatellites Kriiger 1822, which supplants Crassatel/a Lam. 1801,

not of Lam. Prodome 1799, is largely represented in the American

tertiary. The recent C. floridana Dall, described from a young shell,

proves to be the same as C. gibbesii T. & H. Crassinella Guppy is

given only subgeneric standing. C. /unulatus Conr. is restricted to the

fossil, the recent form being C. mactracea Linsley. | ;

THE NAUTILUS. 95

The Astartidz number 22 species, of which seven are new. Cyclas

Bruguiere 1798 (1st species Venus islandica Linn.) replaces Cyprina

Lam. 1818, and is located with 7rapezium and Coralliophaga in the

family Pleurophoridx. Pandora carolinensis Bush is considered the

same as the Miocene P. arenosa Conr. Laternula Bolten 1798 =

Anatina Lam, 1809.

To the readers of Tue Nautiius the many recent changes in

nomenclature may, perhaps, be better understood by the following

extract from the author’s preface: ‘‘ In the years which have elapsed

since this Memoir was begun, the subject of zodlogical nomenclature

has been much discussed and the general consensus of opinion seems

to trend towards the acceptance of names for which no diagnosis was

originally supplied, provided the species cited under them are identi-

fiable. This change from the British Association rules of 1842 is

responsible for much unnecessary overturning of formerly accepted

names with no visible benefit to science, but since it appears to ex-

press the will of the majority, it seems useless to oppose it, and in

Parts 1V—VI it has been complied with, except in the case of the

anonymous auctioneer’s catalogue, known as the ‘ Museum Calonni-

anum.’ This compilation from a manuscript of Hwass, edited by Da

Costa, and printed for the auctioneer, George Humphrey, has usually

been credited to the latter. I confess, my desire to settle the nomen.

clature on a firm basis, though great, has not been equal to the ac-

ceptance of these anonymous, undefined, worthless names, which

would involve the loss of much that is fundamental in the nomencla-

ture of mollusks. I still hope that the common sense of naturalists

will find a way—if necessary, an arbitrary way—to eliminate this

publication from authorized sources of nomenclature. ‘The ‘Museum

Boltenianum’ stands on a different footing, and the principal change

which its acceptance involves in the earlier part of this work is the

substitution of the name Busycon for the more familiar Pulgur.”

The part closes with a “ Discussion of the Geology,” followed by

descriptions of the several stages or horizons and lists of the species

recognized in each, also a summary in tabular form, showing the re-

lations of the faunas to one another. Some idea of the amount of

labor inyolved in preparing this great work may be derived from a

foot-note on page 1552: ‘It may be of interest to note that during

the progress of this work approximately eight thousand three hun-

dred and fifty species have been discussed or compared, and eight

96 THE NAUTILUS.

hundred and sixty new forms described. More than fifty new group-

names, from sections to genera, have been proposed, and more than

five times as many reduced to the rank of synonyms as unnecessary

or belated. The number of species known at: present between the

beginning of the Oligocene and the present fauna is between three

and four thousand, probably less than half as many as will eventually

be obtained and discriminated.” .

The richness of the tertiary fauna is clearly shown by the lists of

species, the bed of the Caloosahatchie River alone containing 639

species, of which 48 per cent. are recent and 28 per cent. are peculiar

to the bed. From the Chipola beds 333 species are recorded, about

one-half being peculiar to it, thirty-five species surviving to the exist-

ing fauna. The Oligocene marl of Bowden, Jamaica, is also very

productive, thus far yielding 435 species, of which 12 per cent. ap

This valuable fauna list enumerates 390 species, including over 300

species not in Mr. Sowerby’s work. Nine species are described as

new. The region covered includes only the coasts of Cape Colony

and Natal. It may be of interest to know that the so-called Pulgur

GUNDLACHIA AND ANCYLUS.

BY WM. H. DALL. :

During the last ten years I have frequently announced to acquaint-

ances and assistants interested in conchology, my belief in certain

propositions hitherto unsupported by proof, bearing on the so-called

genus Gundlachia, viz:

1. That Gundlachia is merely an Ancylus which has under favor-

able circumstances been able to form a calcareous epiphragm and

survive the winter, which ordinarily kills the great mass of individ-

uals, and, while retaining the shell of the first year, to secrete an en-

larged and somewhat discrepant shell during its second summer.

2. That not all Ancyli necessarily have the ability to do this, but

the practice may have developed in certain small species; and in

tropical regions where the dry season takes the place of winter it is

possible that survival may become more or less habitual with some

of these species, though evidence of this is still needed.

On no other hypothesis could I account for the fact that single

specimens, or a small lot of specimens on a single occasion (after a

specially favorable season ?), of Gundlachia have been reported from

various parts of the world and described as species, but which no-

body has been able to find a second time or in any considerable

numbers. Also that the young Gundlachia cannot be distinguished

from an Ancylus and usually resembles some common species of

Ancylus of the same ponds in which the Gundlachia appears ; while

the only species which have been repeatedly collected as Gundlachia

98 THE NAUTILUS.

come from tropical or southern countries. ‘There is nothing dis-

tinctive in the radula or soft parts of Gundluchia, as far as yet ob-

served, to separate it from the analogous Ancylus.

A paper which, for the first time, brings to bear on this hypo-

thesis facts which seem to render it sufficiently acceptable to publish,

has been contributed by Erland Nordenskidld to the Zodlogische

Anzeiger, XXVI, pp. 590-593, July, 1908, with seventeen figures.

In this paper to which the reader may profitably refer, a process

such as my hypothesis assumes is fully illustrated in Ancylus mort-

candi d’Orbigny, from the Chaco region of Brazil, up to the point of

the completion of the epiphragm and the determination of the

identity of the forms bearing it with the typical first-year Ancylus.

The formation of the second-year shell or Gundlachia by these indi-

viduals, alone remains to be demonstrated to establish the hypothesis

as a fact.

NOTES ON THE STRUCTURE OF THE SHELLS OF UNIO.

BY L. 8S. FRIERSON.

The shells of Onzo are stated by most authors to be composed of

three layers, known as the “ epidermis,” the “‘columnar ” or “ pris-

’

matic’ layer, and the ‘ nacreous,” or simply called the “ nacre.”

As a matter of fact, however, these shells are composed of four

layers, the nacre being composed :of two distinct layers. ‘These may

be readily noted in a polished section of some thick-shelled species,

and especially if a species be chosen, such as QObovaria retusa

Lamarck, showing the two layers in different colors. A clearer idea

of the two layers may be obtained if the secreting ‘‘mantle”’ be

studied. This part of the animal, though called by a single name

‘“mantle”’ really is composed of two distinct portions, and should

have two names. That portion extending from the beaks to the

pallial line is thin, and one is tempted to say structureless, while

from the pallial line to the margin, it is thickened, and plentifully .

supplied with nerves and muscles. The extreme edge of this is

thickened, and secretes both the epidermal and columnar layers.

From this edge to the pallial line is secreted a layer of nacreous

material which may be called the extra-pallial layer. If a section

of any thick-shelled species be made, it can easily be seen that the

THE NAUTILUS. 99

elements of growth of this layer are diagonal to the general surface

of the shell. From the pallial line to the beaks is deposited the

fourth, or intra-pallial layer—the elements of which are parallel to

the general surface. The sectionized shell will show the extra-

pallial layer wedge-shaped, with the apex at beak, and base occupy-

ing the distance from the pallial line to the margin, while the intra-

pallial layer is also wedge-shaped, with its apex at the pallial line.

Because the pallial line is composed of very many small muscle-

scars disposed in a line, if the two layers could be separated, a sur-

SUL

oS ieee,

face would be exposed “radially ridged.”” Sometimes, by decay,

this separation is effected, partially, near the beaks, and the “ false

beaks’ so exposed are strikingly ‘‘ radially ridged ’—so much so as

to deceive an expert like Dr. Lea. If a thick-shelled Unio like

Quadrula trigona be burnt, this structure can be very readily demon«

strated.

It is not impossible that this appearance of decayed or fossilized

Unios has given rise to the opinion, as stated by Mr. Chas. T. Simp-

son, that the primeval Unios were provided with “radial beak-

sculpturing.” The difficulty experienced by every collector of ob-

taining living shells showing beak-sculpturing, and the @ priori im-

probability of fossil shells retaining this very perishable character,

lends an air of probability to the above theory, which may be further

strengthened by the curious fact that no North American Unio re-

tains the slightest tendency to show their beaks so sculptured.

LAND SHELLS OF MT. DESERT, MAINE.

BY H. 8. COLTON.

On Mt. Desert Island last summer I found land shells in six local-

ities. At Hall’s Quarries I found Zonitoddes arboreus near the shore

at the edge of the woods. From Seal Harbor I received Vitrea ham-

monis Strom, Pyramidula striatella Anth., Helicodiscus lineatus Say

and Carychium exiguum Say. At Coryledge point under boards

within a yard or two of the place where the beach began, I found

100 THE NAUTILUS.

Pupa muscorum in untold numbers, Cochlicopa lubrica Mill, Vitrea

hammonts Strom, Zonitoides arboreus Say and Succinea obliqua Say.

At Southwest Harbor Village, under planks, by the road-side I

found:

Zonitoides milium Morse. Cochlicopa lubrica Mull.

Vitrina impida Gld. Pyramidula striatella Anth.

Euconulus fulvus Mull. Vallonia excentrica Sterki.

Strobilops labyrinthica Say.

The great majority of the species that I found were in Sea Wall

and McKinley Villages. These two villages were about three miles

apart. Here the conditions were the same. New board-walks were

being built along the road and the planks of the old one were thrown

into the gutter and into the adjoining fields. I found the following

under these boards or in the grass near the boards:

I visited a number of islands but explored only a few carefully.

I spent an hour on the evergreen woods of Suttons and found a few

Zonitoides arboreus Say. An hour on Baker’s Island, an hour on

Black Island and six hours on Little Goat’s Island, revealed me noth-

ing. On Little Ram Island, a rock about a hundred feet long cov-

ered with about three feet of soil which supports a number of dead

spruce trees, I got Zonitoides arboreus and Succinea obliqua under

some dead wood. On Greening’s Island, where I lived and explored

THE NAUTILUS. 101

most carefully, I discovered two specimens of Suceinea avara Say

under a board in a swamp. On Little Cranberry Island, under

boards near the woods, I found:

Cochlicopa lubrica Mill. Agriolimax compestris Binn,

Vitrea hammonis Strom, Pyramidula striatella Anth.

Euconulus fulvus Miill. Succinea avara Say.

With the exception of the places where the board-walk was be-

- ing repaired, land shells were the most plentiful on great Cranberry

Island. The island is shaped like the letter G and is about four

miles long. I explored the western part of the island or the back of

the G most carefully. The western shore is composed of ledges of

solid rock behind which lies an extensive bog. Where the rock

wall is low the surf has built ‘sea walls’? by piling up cobblestones,

making a steep beach back of which lies the swamp. This swamp

and the higher places near the shore are covered with grass, on top

of which the sea in times of storm has cast old planks, stumps, boxes

and all kinds of rubbish. It was under these that the shells were

found. ‘There was one exception however. Pyramidula alternata

Say, I found under stones. I found them within a foot of where the

vegetation ended and the rocks began that went down to the sea.

Indeed all the species enumerated below were found within twenty

feet of the beach. Sprinkled through the grass are the shells of

Buccinum undatum, Littorina and Mytilus edulis. Some have been

washed up, others have been carried by the crows and gulls. It has

been suggested that it is owing to the abundance of calcium carbon-

ate in the soil due to these decomposing shells that land shells are

so very abundant at the edge of the sea.

Little Duck Island lies about eight miles to the southward of Mt.

Desert and is the most isolated that I visited. It is about a half a

mile in diameter and is half covered with a dense growth of woods, >

principally spruce. Half is bare of trees and is covered with coarse

grass, granite ledges out-cropping here and there. Between the

woods ‘and the field there is an area of trees. It was here under

arboreus Say and two specimens of Helix hortensis and P. alternata

Say away from any trees. A yeur ago Succinea obliqua was found

in great abundance around a spring, but I did not notice them there

this year. This year I found them in the area of dead wood.

THE PALEONTOLOGY AND STRATIGRAPHY OF THE MARINE

PLIOCENE AND PLEISTOCENE OF SAN PeEpRo, CaLirornia.—By

Ralph Arnold (Mem. Cal. Acad. Sciences III, 1903). 4to, 420

pp-, 37 plates. This important work, which has engaged Mr.

Arnold’s attention for some years, consists of three parts, of which

Part I is devoted to general descriptions of the Pliocene and Pleisto-

cene beds, their stratigraphy and faunal relations. Mr. Arnold

concludes that during the latter part of the Pliocene the climate was

much colder than at present, 18.5 per cent. of the species of the

108 THE NAUTILUS.

Deadman Island Pliocene being now found living only to the north,

many of them not south of the Puget Sound district. During the*

Pleistocene, warmer climate ensued, the upper San Pedro beds indi-

cating more tropical conditions than those now prevalent. The

marine Pleistocene has been found to be enormously developed on

the West Coast.

Part II, the descriptions of species, occupies the greater portion

of the volume. Nearly all of the species are fully described, and

illustrated by good pen-drawings. Since most of the forms ate still

living, the full descriptions and illustrations will render the work of

great use to students of the recent shells of the West Coast; and it

should have a wide circulation among West Coast conchologists.

Many new forms are described, a large proportion of which will

doubtless be found to be also recent. The nomenclature is fairly

brought up to date, but there are some exceptions which one might

reasonably expect to see corrected, such as the retention of Trophon

belchert in ‘* Chorus,” the use of ‘ Ranella” for Gyrineum, of

‘“ Hipponyx’’ for Amalthea, and of ‘ Phorcus”’ for Chlorostoma

pulligo. Neither of the species bimaculata and callomarginata be-

longs to Clypidella, as was shown over ten years ago. The Chitons

seem to have gone astray as to family classification. The two species

of Planorbis described and figured are incorrectly named. In the

Scaphopoda, Mr. Arnold admits Dentalium hexagonum Sby. and

D. pseudohexagonum Dall, placing D. neohexagonum S. & P. in the

synonymy of both. The fact is that hexagonum is an oriental

species not found in California, and pseudohexagonum is a MSS.

name, not before published. The common Californian species is

rightly known as D. neohexagonum. Similarly, Cadulus fusiformis

S. & P., a species published and figured some years ago, is placed in

the synonymy of the hitherto undefined MSS. name * C. nitentior

Cpr.” The figure and description given fix the name nitentior on

what seems to be the tube of a serpulid annelid. Notwithstanding

these and various other oversights, the nomenclature is in the great.

majority of species abreast of the times. Among many interesting

facts brought out, is the absence of Halvotis before the Pleistocene

in Californian strata. The plates illustrate not only the fossils, but

also characteristic views of the principal terranes.

Part III, bibliography, gives a useful list of works dealing with

West Coast mollusks, including a complete bibliography of the

writings of Dr. R. BE. C. Stearns.—H. A. PF.

SHELL COLLECTING DAYS AT FRENCHMANS’ BAY.

BY DWIGHT BLANEY.

It is with the desire to return some of the pleasure the writer has

derived from the interesting accounts of collecting trips which have

appeared in the NAuTILus, that the following description of a dredg-

ing trip in Frenchmans’ Bay, Maine, has been written:

Taking a calm morning, with the tide nearly at low-water mark,

we start off in a small scow in tow of our fifty-foot steamer. A calm

day is to be preferred, as the labor is much reduced, a rough sea

making it very uncomfortable in the pitching scow.

The scow is fitted with seats, and gives us plenty of room to coil

the 100 fathoms of rope, places for pails, tubs and sieves, with safe

corners for glass jars of sea water. We usually dredge in what we

know as good fishing-ground, as more shells are found in such places,

though all kinds of bottom are tried.

The dredging stations for the day are planned beforehand and we

look forward with no little anticipation to the hauling up of the

dredge.

We are always hoping to find alive the Pecten islandicus, Thracia

conradi, or the Aporrhais occidentalis, as we have only dredged dead

specimens before; and the chance of adding new species to our

collection keeps us continually hard at work.

To-day we try first, some hard bottom off the northern end of

Long Porcupine Island and the first haul brings in about a dozen

fine live specimens of the large scallop, the Pecten tenuicostatus. This

110 THE NAUTILUS.

great scallop, six or seven inches in diameter, is good eating, and we

lay them aside to appear later in a different form on the breakfast

table. The large stones and dead shells are looked over carefully

and we find attached to them the Orueibulum striatum, and the Chi-

tons, Tonicella marmorea, Tachydermon albus, and the Tachydermon

ruber. On a previous trip we dredged a single, fine specimen of the

Hanleya mendicaria. This rare Chiton is usually found in much

deeper water than the bay.

The remaining sand and mud ts now poured into large sieves with

handles and looked over carefully. We find alive the beautiful

Margarita obscura, Margarita undulata and Margarita cinerea.

These are not uncommon, however, and are hurried into the glass

jars of water, to be studied later under the microscope. We are

always glad to find the Scadaria groenlandica, though we find few

alive. Many kinds of Sela are found, among which are the common

Bela incisula, also the Bela sealaris, Bela harpularia, Bela pleuroto-

marta, and the more rare Bela violacea and Bela gouldii. Also in

this section we find the Velutina haliotoidea, Trichotropis borealis, and

the Lunatia groenlandiea, and the Trophon clathratus.

The contents of the sieves are now washed over the side of the

scow; the mud washed away and the cleaned sand and shells poured

into pails, labelled with the station, depth of water and character of

bottom, to be looked over after being dried at home.

A great many specimens are in this way obtained, and much ma-

terial collected to be separated on rainy days.

We move on now a quarter of a mile to a station with muddy bot-

tom at 25 fathoms, where in a few hauls of black, sticky mud we find

numbers of Leda tenuisulcata, Yoldia thraciaeformis and Yoldia sapo-

tilla, with quantities of Astarte undata, Cardita borealis, a few of the

Cardita novangliae, Cardium pinnulatum, Thracia truncata, also, of

course, great numbers of Nucula proxima, Nucula delphinodonta and

Nueula tenuis.

Another haul nearer shore, on harder bottom, brings us A/ssoa

carinata and Rissoa exarata. Here also we find the Chrysodomus

decemcostatus, the Stpho stimpsonti and Sipho pygmaeus, and a few

young Serripes groenlandicus, with the pretty zig-zag markings which

disappear in the older specimens.

The material is also washed and sifted after being picked over,

and with aching backs we rest in the scow as we go ploughing

THE NAUTILUS. Lid

through the water on the way home. It is by no means easy work

hauling the dredge, leaning over the side of the scow to wash the

contents of the sieves, and we have narrow escapes from sea-sickness

on rough days.

Outside the islands, in deep water, we have dredged the Denta-

lium striolatum, valves of the Panomya norvegica, Mya truncata and

Liocyma fluctuosa, and alive the Menestho albula, Admete couthouyt,

Puncturella noachina, Lepeta caeca, Modiolaria nigra, Modiolaria dis-

cors and Modiolaria corrugata, also the Cardium tslandicum.

On arriving home, the material collected is spread in the sieves to

dry in the sun, and we find it difficult to wait until it is dry enough

to bring into the work room. It isonly by careful picking over that

the smaller species are obtained and it is in this way that we get good

series of the Rissotde. The Lissoa, or rather Cingula castanea,

Rissoella eburnea, Turbonella nivea, Turritella acicula, and Turritella

erosa, Molleria costulata, Retusa gouldii and Retusa petenuis, and the

Diaphana debilis.

Many live specimens are put into shallow dishes, and under the

microscope it is most interesting to watch the Margaritas, Belas,

Lunatias and the active Yoldias moving about.

A day’s dredging thus means a good deal of work, and after all

comes the labelling and putting in the cabinet, last but not least of

a day’s dredging.

OBSERVATIONS ON THE GENUS QUADRULA.

BY L. S. FRIERSON.

In his admirable Synopsis of the Naiades, Mr. Chas. T. Simpson

says (page 766), that although he had examined thousands of ani-

mals of the plicata group of Quadrula, he had never seen but a

single one having eggs in the gills, and that other students had found

them equally barren. In NautTi.us (vol. xv, no. 4, p. 39), H, von

Ihering speaks of the specimen of Q. heros Say, examined by Lea, and

of the specimen seen by Sterki, and he seems to be rather doubtful

whether Quadrula (of this group at all events) always carry eggs in

all four gills. My observations of late have been singularly lucky in

this respect and will, I think. settle this point. The first specimen

LY THE NAUTILUS.

found gravid by me (of this group) was a Q. trapezoides, May 10,

1901. Since that time I have opened and examined dozens of gravid

specimens. ‘They are gravid from May to September, after which I

have never found eggs in their gills. Of Quadrula perplicatus Con-

rad, I have taken but two specimens, June 7, 1901, and August 19,

1903. In one the gills (all four) were but one-half filled with eggs,

the lower half of each gill being empty. The other was a normal

Quadrula. Quadrula heros had never been taken gravid by me

until October 8, 1908, a young specimen proved to be in that condi-

tion. Its gills (four) were packed full of uncountable ova. These,

under the microscope, were perfectly spherical and undeveloped,

showing that they were recently extruded from the ovary.

On November 24, 1903, a batch of about fifty were brought me by

a negro, to be sent to Mr. Chas. Conner, of Philadelphia. After

packing fifteen or twenty for him, the remainder were opened, and to

my surprise, fully half were gravid. Mr. Conner reported several of

his also gravid. . Most of these eggs were not yet developed into

glochidia, several specimens having eggs in the ** mulberry stage.’’

January 7, 1904, out of seven specimens opened, four proved to

be gravid. These were full of glochidia, but they did not seem to

be perfectly developed or ready to be extruded, being very sluggish.

These observations prove two points: First, that the plicata group

belongs safely to Quadrula, as defined by Mr. Simpson, and that the

specimen noted by Sterki and H. von Ihering must have been ab-

normal. Secondly, that the seasons of ovulation are different in

different species of the same group, Q. trapezoides being a summer

breeder, while Q. heros is an autumn or winter breeder.

-THE MOLLUSKS OF CEDAR LAKE, INDIANA.

BY FRANK COLLINS BAKER.

Some months ago, the Monon Railroad invited the writer to visit

Cedar Lake, Indiana, to witness the seining of the lake for “ pirate”

fish, such as carp, gars and pickerel. Incidentally a collection of the

mollusks was made, which seems of more than passing interest. The

lake is a body of cold water, of considerable extent and of great depth

in places. The species collected are as follows :

THE NAUTILUS. 113

Valvata tricarinata Say.

Valvata tricarinata var. confusa Walker.

Valvata bicarinata Lea.

Valvata bicarinata var. normalis Walker.

A quantitative study of the Valvatas collected is very interesting.

275 specimens were collected, of which 117 were typical tr¢carinata,

104 dbicarinata var. normalis, 31 tricarinata var. confusa, 21 bicart-

nata, 1 specimen was 4-carinate and 1 specimen of bécarinata was

almost ecarinate.

The most common forms of the carinate Valvatas would seem to

be tricarinata and bicarinata var. normalis ; typical bicarinata seem-—

‘ing the rarest.

Amnicola limosa Say. Common. -

Amnicola walkeri Pilsbry. A single specimen of this very distinct

species was found, but a careful search of the lake would probably

reveal a number of specimens. It is one of the most characteristic

of the fresh-water mollusks.

Planorbis campanulatus Say. Very common.

Planorbis bicarinatus Say. Common.

Planorbis exacutus Say. Apparently rare, as only two specimens

were found.

Planorbis parvus Say. Very common.

Limnea caperata Say. Fairly common.

Limnea humilis Say. Not common.

-Physa heterostropha Say. Not common.

Physa gyrina Say. Not common.

Sucetnea retusa Lea. Common.

A NEW FLORIDIAN AMNICOLA.

BY H. A. PILSBRY.

Amanicola augustina n. sp.

Shell narrowly umbilicate, brown or olive-brown, smooth, ovate~

conic ; spire convexly conic, the apex rather obtuse. Whorls 42,

quite convex, separated by deeply-impressed sutures. Aperture

about half as long as the shell, broadly ovate, obtusely angular above;

peristome acute, continuous, dark-edged, adnate to the preceding

114 THE NAUTILUS.

whorl for a short distance above. Operculum as usual in the genus.

Length 3.2, diam. 2.2, longest axis of aperture 1.6 mm.

A small stream near St. Augustine, Florida. Types no. 58088,

A. N.S. P., collected by Charles W. Johnson.

This species is larger than A. floridana Ffid., with a longer spire

and more obtuse apex. It was collected in some quantity by Mr.

Johnson many years ago. It was at first identified as Bythinella

tenuipes Couper, and so recorded in NavuTILvs iii, p. 187; but fur-

ther investigation has shown that it belongs to a different group of

species.

NOTES ON THE NOMENCLATURE OF THE PUPACEA AND

ASSOCIATED FORMS.

BY W. H. DALL.

The publication of Mr. Woodward’s list of British land shells and

certain work. on which I have been engaged, have recently drawn

my attention to this subject, which I have found so involved and so

imperfectly represented in many publications on the group as to lead

me toa tolerably thorough investigation, some of the results of which

are here expressed.

I take it as axiomatic that (1) the type ofa group must be one of

the species mentioned when the name of the group was first pub-

lished ; (2) that in consolidating several old genera one of the old

names and not a new one must be employed for the consolidated

group; (3) that when a heterogeneous group is subdivided, its name

must be retained for one of the resulting subdivisions; and (4) that

we are under no obligation to accept the first species of a list as the

type of a group for which no type has been selected by the original

author, but that we should accept the decision of the first subsequent

author who undertakes to select types from the original Jist in revis-

ing it.

In the following notes only the question of nomenclature is con-

sidered, the validity of the sections is left to the specialist in this

difficult group. In matters of specific synonymy, I have depended

on L. Pfeiffer, Pilsbry and Sterki.

Isthmia Gray, 1821. The sole example cited is Vertigo pygmea

Drap., which must be regarded as the type. Stauwrodon Lowe, 1852,

and Dexiogyra Stabile, 1864, are synonymous.

THE NAUTILUS. 115

Jaminea Risso, 1826; not Brown, 1827. Brown cites the name

as of Bruguiere, but I have found no reference to this origin of it

elsewhere. MRisso’s group is heterogeneous, and was intended for the

large Pupas in which the body whorl interrupts the peristome, while

for the small species of Vertigo, etc., with a continuous peristome, he

proposed a genus Saraphia, none of the species contained in which

can be positively recognized. Risso’s first species is Vertigo minu-

tissiéma Hartmann, which should properly have been placed in Sara-

phia. Those which agree more or less with his diagnosis have since

been separated into a number of groups in the following order chro-

nologically: Adbida, Sphyradium, Eucore, Torquatella. There are

also three unidentifiable species. Risso’s second species was the last

to be separated and should have been reserved for Jaminia, of which

Torquatella must be regarded as a synonym. This type is Turbo

muscorum Linné, not Draparnaud.

Chondrus, Cuvier, 1817, not of Lamouroux, 1813. Cuvier’s

Chondrus was divided into two groups not named and with no type

cited. In 1821, Gray cited Pupa cinerea Drap., as an example, but

Cuvier’s name is pre-occupied in Polyps. The next name for this

group is Torguilla Studer, 1820, type P. secale Drap. Torquilla had

been used by Brisson in 1760 for a bird. Now Brisson is a non-

binominal writer and his genera have only been adopted by an arbi-

trary over-riding of the rules of nomenclature. Nevertheless I am

inclined to believe that such arbitrary acts are sometimes beneficial

to science and to be praised rather than blamed, when the occasion

is suitable, and the consensus of opinion of the specialists in the de-

partment affected, practically unanimous. Rejecting Zorquilla, the

next name in order is Abida Leach, in Turton, 1831, sole example

cited P. secale, which must be regarded as the type. Several other

names have been proposed to take the place of Chondrus by too hasty

writers, such are Granaria Held, 1837, Pupella Swainson, 1840,

Chondrina Reichenbach, 1847; while further subdivisions of the type

are Sandahlia and Granopupa Westerlund, 1887.

Alza Jeffreys, 1830. This heterogeneous group, beside species of

Isthmia and Jaminia, contained originally Pupa edentula Drap.,

afterward separated as Sphyradium and Pupa minutissima Hartmann,

which must be taken as the type.

Pupilla Leach, in Turton. 1831. Two species are cited, one being

already the type of Jaminia, the other, namely, P. umbilicata Drap.,

116 , THE NAUTILUS.

necessarily becomes the type of Pupilla. Gastrodon Lowe, 1852,

not of Rafinesque, 1815, and Reinhardtia Boettger, 1878, are syn-

onymous. Lauria Gray, 1840, was proposed for P. umbilicata and

P. anglica Feér.; if Lauria is retained at all it must be for the latter,

in which case Le?vostyla Lowe, 1854, is synonymous.

Lucore Agassiz, in Charpentier, 1837, was proposed for P. tridens

and P. quadridens Drap. Gonodon Held, Dec., 1837, Chondrula

Beck, 1838, and Chondrulus Westerlund, 1890, appear to be syn-

onymous.

Sphyradium Agassiz, 1837, has been adopted for P. edentula Drap.,

by the process of elimination; Paludinella Lowe, 1852, not of Pfeif-

fer, 1841; Edentulina Clessin, 1876, not of Pfeiffer, 1855; and Col-

umella Westerlund, 1876, are synonymous, Sphyradium (ferrart)

Hartmann, 1840, has been named Coryna by Westerlund, 1887.

Sphyradium Martens, in Albers, 1860, is a synonym of Orewla Held.

Faula H. and A. Adams, 1855, not of Blanchard, 1850, was re-

named Fauxulus by Schaufuss in 1869. P. capensis Kurr, appears

to be the type.

Ptychochilus Boettger, 1880, founded on Pupa tantilla Gould,

seems to have priority over Mesopupa Pilsbry, 1900. Bifidaria

Sterki, in Pilsbry, 1891, contained two species, P. contracta Say and

P. servilis Gould. P. contracta being taken as type by Sterki in

1892, for his section Albinula, P. servilis must be considered the type

of Bifidaria s. s.,and not P. hordacea, for which Sterki’s Hubifidaria,

18938, will stand, if the sections are valid otherwise.

DESCRIPTIONS OF NEW JAPANESE LAND SHELLS.

BY H. A. PILSBRY AND Y. HIRASE.

Eulota chishimana n. sp.

Shell umbilicate, depressed globose, with conic spire, rather thin,

pale yellow, becoming white on the spire, the last whorl encircled

by three bands, that at the periphery dark chestnut and sharply de-

fined, the others much paler, reddish-brown, and indistinctly defined,

one in the middle of the base, the other on the upper surface, as-

cending the spire midway between sutures on the penult. whorl, or

obsolete except on the last whorl. There are also one or two dark

THE NAUTILUS. 117

oblique streaks indicating places of growth-arrest. Sculpture of

irregular, rough and coarse wrinkles in the direction of growth lines,

and under the lens, irregular fine spiral lines are seen. The spire

is much smoother than the last whorl. Whorls about 6, moderately

convex, regularly increasing, the last rounded peripherally, not de-

scending in front. Aperture not very oblique, lunate, white and

conspicuously banded within. Lip broadly reflexed, strengthened by

a narrow callous ridge within, the face flat or concave, the thin outer

portion dark flesh colored, the ridge lighter or white. The peri-

pheral band extends to the lip-edge.

Alt. 20.5, diam. 26,5 mm.

Alt. 19.5, diam. 25 mm.

Kunashiri Island, in the Chishima (Kuril) chain. Types no.

86324 A. N.S. P., from no. 1153 of Mr. Hirase’s collection.

This fine Huhadra, of a type unknown in the main island of Japan,

is the first to be reported from the Kuril chain. Other land shells

from Kunasbiri will be described in a future communication.

Vitrea radiatula var. radiata n. var.

This variety is smaller than radiatula, and of a pale reddish-brown

tint, not greenish. It is decidedly larger than V. radiatella (Reinh.),

and less depressed. Alt. 2, diam. 4 mm.

Toya, Kuziro, in eastern Yesso (Hokkaido). Types no. 85788

A. N.S. P., from no. 1147 of Mr. Hirase’s collection.

Alyceus awaensis n. sp.

This shell is larger and more elevated than. A. reinhardti, pale

brown. Sculptured with spaced riblets, which on the swollen last

half whorl became fine and densely crowded. The neck is moder-

ately contracted and smooth. The aperture is circular, lip thin, nar-

rowly reflexed. There are sometimes some spiral striz on the spire,

not visible in all specimens. Alt. 3.8, diam. 2.6 mm.

Hiyama, Awa, Island of Shikoku. Types no. 84958 A. N.S. P.,

from no. 1083 of Mr. Hirase’s collection.

of Mr. Hirase’s collection.

Vertigo japonica un. sp.

Sheli minute, oblong, about equally obtuse at both ends; brown,

nearly smooth. Whorls 5, parted by deep sutures, the last whorl

tapering downwards, impressed by a deep furrow terminating above

the middle of the outer lip. Aperture irregularly ovate, contracted

by four teeth: a long parietal lamella, a strong columellar lamella

and two short, deeply-placed palatal plice. Peristome thin, very

narrowly expanded, the outer lip projecting forward and bent inward

at tbe upper third, at the termination of the external furrow. Alt.

1.7, diam, 1 mm.

Ikusagawa, Ojima. Types no. 85746 A. N.S. P., from no. 11438

of Mr. Hirase’s collection.

This species from southern Yesso is related to V. hiraset from

Kyutshi, but differs from that species in having much larger teeth.

Both belong to a group of Vertigines which lives throughout the

whole northern part of the Holarctic region.

Nesopupa tamagonart n. sp.

Shell extremely short and broad, very obtuse at both ends,

chestnut-brown, nearly smooth, somewhat glossy. Whorls 44,

rapidly increasing, parted by slightly-impressed sutures; the last

whorl forming more than half the length of the shell, tapering down-

wards, bearing a strong crest or ridge close behind the outer lip.

Aperture small, squarish-oval, obstructed by six teeth: a long, enter-

ing parietal and a much shorter angular lamella; a deeply-placed

columellar lamella; a small, tubercular basal plica, and two short

but high lamellar palatal plice. Alt. 1.3, diam. 1 mm.

Differs from C. pessimum in being smaller and less conic, more of

an oblong shape. Harutori, Hokkaido. Types no. 85772 A. N.S. P.,

from no. 1144 of Mr. Hirase’s. collection. .

LE PERE LAMBERT, S§. M.

BY CHARLES HEDLEY.

Half a century ago, a little band of Marist missionaries landed in

New Caledonia to convert to their faith the cannibal savages of that

island. For years, lance or casse-téte daily threatened them with

cruel death. They knew no society but the disgusting companionship

of brutal savages. From the danger, hardships and squalor of their

life, these cultured gentlemen turned for relaxation to the pleasant

paths of science. ‘To them we owe most of our knowledge of the

fauna, flora, geology and ethnology of New Caledonia. One by one,

Montrouzier, Thomassin, Rougeyron—this noble company of hero,

pauper, saint and savant—have gone to their rest. The last patri-

arch, Father Pierre Lambert, died in Noumea, on November 3,

1903, aged 82 years.

He wrote a few short papers in the Journal de Conchyliologie, but

he will be chiefly remembered as a collector. One of the finest of

the cones bears his name, as does one of the largest Placostylus.

Souverbie dedicated to him species of Pecten, Melanopsis, Trochus,

Euchelus, Xenophora, Mitra, Cuncellaria, Pleurotoma, Rissoina and

Eulima, also the genus Lambertia.

Pere Lambert published a memoir on Ethnology—Moeurs et

‘Superstitions des Néo-Calédoniens, Noumea, 1900, pp. vi, 360, with

60 illustrations. An important but little known book.

GENERAL NOTES.

ANCYLI ADHERING TO WATER BEETLES.—Two interesting ex-

amples of Ancyli attached to the elytra of water beetles, recently

came under my observation through the kindness of Mr. Albert P.

Morse, who collected them at Wellesley, Mass. One a Dinutes

(whirligig beetle), collected April 26, 1900, has an Ancylus fuscus

Adams, 4x 2.5 mm., situated dorsally and extending about equally

over each elytron; whether it adhered with sufficient strength to

prevent the beetle flying, can only be surmised. The habit of Dinutes

in gyrating on the surface of the water, often in the bright sun-light

for hours at a time, is not strictly conducive to the life of an Ancylus

thus situated, for it would be entirely out of water while the beetle

was on the surface, although during the early spring the beetle prob-

ably spent most of its time beneath the water.

The other, a Dytiscus, collected in October, 1898, carried an An-

cylus parallelus Hald., 5x 2.5 mm., near the end of the left elytron.

Both cases present an interesting factor in the distribution of species,

which probably in many instances accounts for the sudden appear-

ance of mollusks in small, artificial ponds.—C. W. JoHnson.

Criam-orovus Crows.—The following newspaper clipping, if true,

shows that the amiable, inoffensive clams of the Northwest coast are

having a hard time of it, and are entitled to the sympathy of all con-

chologists without distinction of age, sex or color:

‘‘ Scare-crows are now placed upon slate roofs in Victoria, B. C.

The crows, which swarm on the beach and dig for clams, fly over the

buildings and drop the clams on the roof, by this means breaking the

shells and leaving the meat free to be eaten. In many cases, when

the clams were dropped, the slate would be broken.”

Such conduct on the part of the crows is certainly discreditable ;

they should be placed on the black-list.

Ill fare the clams to hungry crows a prey,

And brought to grief in such a crow-ill way.

The clam is probably Saxidomus giganteus Desh., quite common

in the Vancouver region and the principal edible clam of both

‘‘ Injuns ”’ and white folks thereabout, and solid enough to break roof

slates if not political ones, when dropped from a considerable elevation,

S. giganteus is abundant between ordinary tide marks; it is great in

soup; an excellent clam.—Rost. E. C. Stearns, Los Angeles, Cal.

HELIX HORTENSIS IN NEW ENGLAND.

BY REV. HENRY. W. WINKLEY.

The following is a suggestion. I cannot say that I am convinced

that it is a proof, but I offer these thoughts for what they are worth.

We must associate... hortensis with northern European forms rather

than with the American land shells. Its distribution in New Eng-

land is most singular, limited as it is to widely separated spots,

mostly small islands of the east coast. It certainly cannot have had

the same migration as Polygyra or Pyramidula or it would be dis-

tributed as they are. Undoubtedly at the close of the glacial period,

the American types worked north and east into New England; but #.

hortensis was not one of them. That it came from Europe is evident.

Commerce-voyages of Norsemen or other explorers: have been sug-

gested. This theory becomes absurd when one examines the locali-

ties where H. hortensis lives. ‘These places are not ports and never

have been. Some of them are the last places a man would land, not

the first. Let us now ask the question of an earlier migration..-

Circumpolar species exist. Other forms common.to Europe and

America would make an interesting study.. That there was a pre-

glacial period when forms migrated around the northern regions is a

settled fact. Did H, hortensis come then and survive?. The writer

has been much interested in the glacial theory, and has done some

field work on the New England area. That the glacier covered all

of New England is an accepted fact, but when we say all, is there

not a chance for exceptions. Along the southern coast we may point

122 THE NAUTILUS.

to Long Island as a terminus. The sound is not deep and tides not

great, this barrier would be and was crossed. ‘The eastern coast is

different. The trend of the ice, though slightly deflected towards

the east, was in a southerly direction ; comparatively little passed off

the east coast. Add now a study of Greenland, as it is under conti-

nental glaciation conditions and probably exactly as New England

was. Peary’s exploration shows a range of animals like the musk-

ox, arctic wolf and others at Independence Bay, and practically the

extreme northern limit of Greenland, and this implies food on which

they live. In other words, Greenland under a glacier yet has a

shore line of animal and vegetable life. The distribution of ZH.

hortensis fits the theory that it is a survivor. The present abodes

are such that it could not have been carried from one to the other

and not have found a home on the mainland more than it has. On

the other hand Grand Manan, outer islands in Casco Bay, the ex-

tremity of Cape Ann and Cape Cod, are places that would be last

resorts. A more exhaustive treatment of the subject would deal

with elevation and subsidence, possible islands or land in the east

now submerged. The stronger tides that would break up a mass of

ice extending seaward. I leave these topics and present only the

simple suggestion.

A NEW SPECIES OF PERIPLOMA FROM CALIFORNIA.

BY WILLIAM HEALEY DALL.

Periploma sulcata n. s.

Shell rotund, white, with the left valve flatter, thin, sculptured

with numerous, close-set, irregularly concentric, more or less inter-

rupted, low ridges, separated by subequal shallow interspaces ; the

surface is also microscopically shagreened, and there is a low rib ex-

tending from the beak to the lower margin of the ill-defined rostrum

and an ill-defined furrow radiating from the beak toward the anter-

ior base, in the right valve; beaks low, distinctly fissured ; anterior

dorsal hingeline rounded, posterior ditto, shorter, nearly rectilinear,

forming with the elevated rib a subtriangular space which is free

from the undulations which cover the rest of the shell; interior

shining, hardly nacreous, the muscular impressions very smal!, the

pallial line obscure ; chondrophores prominent, spoon-shaped, extend-

THE NAUTILUS. 123

ing obliquely forward, and with their connecting resilium sustaining

a proportionately large triangular lithodesma; the chondrophores

are supported behind by well-developed clavicular props, which are

inserted posteriorly on the surface of tlie valve below the linear

hingeline. Length 32, height 27, diameter of right valve 6 and of

the left valve 4 mm.

This elegant shell, in a somewhat damaged condition, was thrown

upon the beach at San Pedro, Cal., after one of the heavy winter

storms and collected by Mrs. T. 8. Oldroyd, to whom we owe so

many additions to the fauna of this region.

This species is, we believe, the first Periploma known to possess an

undulated sculpture, and bears to those of the ordinary type such a

relation as that of Cyathodonta to Thracia or Labiosa to Raeta. The

differences of sculpture and in the form of the lithodesma suggest

that, as in the case above cited, P. sulcata is entitled to a sectional

name for which Halistrepta is proposed.

Adult shell large, rather slender, moderately curved posteriorly,

the latter half nearly straight; cream-white, often yellowish toward

the mouth, shining where not eroded, earlier portion usually dull and

chalky because of erosion; growth-lines fine, irregular, distinct,

rarely an encircling groove due to repaired fracture; at the apex

there are longitudinal, low, rounded, inconspicuous threads, of which

seven or eight are more prominent and three to six in each inter-

space are less prominent’; these die out, and fine, superficial striae

appear, visible under the glass and continued to the mouth of the

shell, seven or eight per millimeter of circumference ; aperture

simple, circular, mouth slightly oblique.

Two specimens measure: length 64.5, diam. of aperture 5.3, of

64.0, diam. of aperture 4.7, of apex 1.4, at middle 4.2, height of

eight angled, the angles defined by sharp ribs with channeled inter-

spaces, then passing into the sculpture of the adult by successive in-

terpolations of secondary riblets, while the primary ribs lose in prom-

inence and the section of the shell becomes circular.

University of California Marine Biological Laboratory: Station

12, Vincente (or Redondo) Submerged Valley, Santa Monica Bay,

145 fathoms, temp. 45.5° F., bottom sand and mud; also scattering

specimens from station 14 off Point Fermin, 100' fathoms, temp.

46°; station 70, La Jolla Submerged Valley, between 117 and 54

fathoms ; station 79, off San Diego, 64 fathoms.

The Vincente submerged valley where this species was found in

considerable numbers, is one of a series of such valleys described and

mapped by Prof. George Davidson, of the University of California,

in Proc. Cal. Acad. Sci., 3 Ser. Geology, Vol. 1, No. 2. Opposite

Redondo the 100-fathom line marks the edge of a gently sloping,

submarine plateau which extends seaward about seven miles. Out-

side of this plateau the bottom descends much more abruptly. The

Vincente valley is nearly 300 fathoms deep and about one and one-

half miles wide where it breaks through the edge of the plateau. It

carries a depth of 100 fathoms to within one and one-half miles of

the beach, thus bringing the colder water of greater depths, with

its accompanying fauna, close inshore. It is probable that the

Dentalium here described will be found in deeper water as marine

exploration proceeds along the coast of southern California.

The sculpture of this fine, large species recalls D. ceratum Dall

(Florida, Cuba, Barbados), but the former is larger, the adult shell

is proportionately wider, the young is more attenuated at the apex,

and the superficial striae are continued to the mouth, even on the

largest specimens. At the length of Dall’s species, D. vallicolens is

more than twice as wide. The peculiar sculpture of the earlier por-

tion and the striation of the latter, readily separate the present

species from D. pretiosum and D. indianorum, even if the angled

apex be lost, as is almost invariably the case in the adult. Erosion

has in some specimens proceeded so far that patches only of the

outer layer of shell are left. In others it seems to have attacked the

shell beneath the outer layer so that longitudinal lines and encircling

rings of opaque white appear beneath the outer, shining layer which

then begins to scale off.

NOTES ON THE MOLLUSCA OF THE BERMUDA ISLANDS.

BY C. ABBOTT DAVIS, S. B.

Last July and August were profitably spent in collecting insects

and mollusks among the three hundred beautiful islands now called

the Bermudas. Like the Hawaiian group, they are chiefly interest-

ing because of their isolated geographical position, being nearly 700

miles distant from any other land. Commerce, however, is rapidly

changing the fanna and flora of Bermuda to such an extent that old

records, 2. e., records of twenty years standing, are obsolete or unre-

liable. Large quantities of West Indian shells are constantly being

brought to the island to sell to the unsophisticated traveller, and some

of the stores actually sell these shells as Bermudian. Even the

native colored boys are anxious to sell shells for ‘* tuppence,”’ and

they are not particular about the historical side, so that one has to

beware of all shells not collected in situ.

The expeditions of Prof. Helprin in the summer of 1888, and of

Prof. Verrill in the spring of 1898 and of 1901, form the nucleus of

most of the authentic published data. I had pianned a trip to Ber-

‘muda for July and August 1903, but upon learning of the Bristol-

Mark expedition, I decided to go with them, and the following notes

_ are a part of the records of our trip.

In 1900, Dr. Pilsbry revised the “ Air-breathing Mollusks of the

Bermudas,” and my research differs little except in minor details.

For instance, he agrees with Mr. Smith that Suceznea bermudensis

Pfr., is S. barbadensis Guild., but states that the animals need a

careful study. I agree with the latter statement and as proof of it

illustrate three Bermudian forms. Fig. 1 is the common form, Fig.

2 was occasionally taken at Flatts, Fig. 3 is the fossil variety.

Physa acuta Drap., has not been recorded since G. Brown Goodes’

record of 1888. We took it from rain-water tanks in Devonshire

Swamp.

The variety pulchella Pfr., of Truncatella caribeensis Sowb., is

always found dead. This, taken with the fact that this mollusk lives

at the high-tide mark, and is therefore apt to be water-worn, makes

_ pulchella simply a worn carribeensis.

In a lot of several hundred carribexensis received recently from the

| West Indies, there is a complete series showing the wear on these

126 THE NAUTILUS.

shells, even to fresh transparent specimens. Prof. Verrill has lately

addeu the following to Dr. Pilsbry’s list :

Blauneria heteroclita Montg., Hyalina lucida Drap.

Peciloronites zonata Verr. (Fig. 17), Siphon henica Verr.

My records add the following:

Carychium exiguum Say. (var.). Sub-fossil.

Vitrea cellaria Mull. Several at Hamilton.

Helix pisana Mill. Several at St. Georges (Fig. 18).

Planorbis dilatatus Gld. Dev. Swamps, (Brackish water).

Paludestrina tenuipes Cooper (var.). Eve’s Pond.

The beautiful genus Melampus needs revision, and as I collected

(personally) several quarts of these bewildering shells, I will attempt

the following key to the Bermudian forms:

A. Aperture narrow and short, shells small, pointed at both ends,

greasy, brownish or blackish, no teeth (see Fig. 4).

M. bulloides Mont.

B. Aperture wider and longer, at the extreme base a very promi-

nent fold, shells larger, apex pointed, greasy, color brownish

or purplish, with one or more revolving white or yellowish

bands, row of teeth within the outer lip very numerois, (Fig.

5). M. flavus Gmel.

1. Color plain brown or purple, no stripes, (Fig. 6).

Var. purpureus n. V.

2. Size and shape same as purpureus, immaculate white

when alive, rare, found only at Hungry Bay, (Fig. 7).

Var. albus n. v.

C. Aperture still wider, shell wide at the top, apex abrupt, two or

more well developed teeth on the inner lip, often attaining to

double the size of flavus, not green, (Fig. 8 is the Florida

form). M. coffeus Linn.

1. Larger, and apex more pointed than in coffeus, the row

of teeth in outer lip very irregular and uneven, banded

spirally, with brown and white, width of bands very trreg-

ular, (Vin. 9). Var. agundlachi, Pfr.

2. Pilsbry says: ‘* Scarcely if at all to be distinguished from

the prior MW. gundlachi Pfr., but not attaining so large a

size.’ These are probably the juvenile gundlachi, the

lack of color and lustre in the large ones being due to

longer exposure and yet they look like another variety so

the smaller ones are called (Fig.10). Var. redfieldi, Pfr.

THE NAUTILUS. L2e

3. Size and shape same, but the revolving bands of light and

dark color alternate evenly, (Fig. 11).

Var. alternatus n. v.

4, Smaller, darker, polished, beautifully mottled with more

or less prominent vertical stripes, (Fig. 12).

Var. verticalis n. v.

5. Stout, plain brown form, with no markings whatever.

(Fig. 13). Var. bishopit n. v.

Named in honor of mine host Mr. Geo. A. Bishop, Supt. of Public

Gardens, Hamilton, Bermuda.

As to Siphonaria, Verrill has described in the ‘* Transactions of

the Conn. Academy of Science,’’ a species called S. heniea. So far

as is known, only one specimen—-the type—is in existence. This

was taken at Bailey Bay on the north shore. We collected over

three pints of S. alternata Say, and found many of the var. brunnea

Hanley, also two others.

2. Shell small (size 16x13 mm.), blackish, opaque opalescent,

rare, Hungry Bay, south shore (Fig. 15).

3. Intermediate in size and coloration between brunnea and opal-

escens.

Var. opalescens n. v.

Very thin, translucent, always distinguished by radial black

lines from apex to margin, covering the whole or a part of the inner

surface. Common on the south shore at high-tide mark (Fig. 16).

. Var. intermedia n. v.

There are undoubtedly many marine species which might be

added to the published lists of Dall, Heilprin, Verrill, and others ;

but the great difficulty just now is to eliminate equivalent nomencla-

ture. I have not seen records of the following species taken by us

in Bermuda:

Acmeza punctulata Gmel.

Anachis catenata Sowb.

Alabina adamsii Dall.

Asaphis deflorata Linn.

Bittium varium Pfr.

Chione beaut Recl.

Chione pygmza Lam.

Ooralliophila abbreviata Lam.

Oypreacardia hornbeckiana

Cythara simulata Rve.

Ocinebra intermedia Ads.

Nassa consensa Rav.

Natica livida Pfr.

Nitidella cribraria Linn.

Olivella rosalina Duel.

Ostrea folium Linn.

Pecten ornatus Lam.

Pitaria fulminata Mke.

Purpura undata Lam.

Rissoina pulehra Ads.

Semela proficua Pult.

128 THE NAUTILUS.

Eulima gracilis Ads. Spirula australis Lam.

Gastrochena ovata Sby. Tellina promera Dall.

(Fig. 20.) Tellina sybaritica Dall.

Litiopa bombyx Kein.

Vermetus erectus Dall. This shell is quite common, but generally

has the erect portion broken off, as in Fig. 19.

The following are undoubtedly new forms. Cotypes of each are

deposited (with the Melampus and Siphonaria) in the museums at

Washington, Philadelphia, Boston and Providence.

Gastrochenu mowbrayi sp. n. (Fig. 21).

This has often been mistaken for a juvenile G. ovata, (Fig. 20) as

it resembles ovata in shape and color, but neither in size, nor habitat.

In Bermuda G. ovata has an alt. of 20 mm. and bores a hole about

10 mm. in diameter in the solid brain-corals, or shell-rock.

On the other hand, G. mowbdray? is found in the dead or dying stems

of the branch coral (Oculina) the entire stem of which could be put

into a tube of ovata. G. mowbrayt occupies a cavity a little larger

than the shell (which is about 6x 8 mm., the cut showing an ex-

tremely large specimen) with a small opening to the outer surface of

the coral. These shells are often grouped so closely together, as to

undermine the strength of the coral, (see Fig. 22). Locality, Har-

rington Sound, dredged in 20 to 40 ft. Named in honor of Mr.

Lewis Mowbray an enthusiastic Bermudian naturalist.

Tellina levigata Linn., var. stella n. v.

T. levigata is called the ‘‘sunset shell’? by the natives, and it

well deserves the name on account of its beautiful bands of orange

or pink alternating with delicate yellow tints. About one out of

twenty of these shells has diverging, radial pink rays (like 7.

radiata). For this nameless variety I propose the name stedla

(Fig. 34) collected at Flatt’s Inlet.

Volvaria avena Lam., var. southwicki n. v.

Volvaria avena (Fig. 23) is common along the north shore of

Bermuda, and is widely known and easily recognized by its con-

spicuous transverse orange bands, size 9 x 3 mm.

On Hamilton Beach I found a smaller constant variety (Fig. 24)

which had a uniformly dark, mottled ground with no bands of color.

Alt.6x2mm. This variety is named after my friend, Mr. Jas.

Key to the Bermudian Species of the Genus Cerithium.

The species of this genus were the hardest to revise owing to the

fact that the descriptions being brief and often inaccurately figured,

no two museums have them named alike. A generous use of the

microscope is necessary to distinguish species, and while there are

undoubtedly intergrades, the majority are I think, distinct species

and not varieties. They are so dissimilar that they can be readily

separated. Most of the species may be picked up in Bermuda by

the thousand. I brought home at least a half bushel for study.

A. Very small, jet-black inside and out, often decollate, nodules

in vertical rows of three dashes. Bermuda form, Fig. 25; Haiti

form, Fig. 26; white-tipped Florida form, Fig. 27.

C. minimum Gmel.

B. Larger, stouter, plain black or dirty brown inside and out,

spirals very uneven, nodules in vertical rows of three dots

(Fig. 28). C. nigrescens Mke.

C. Shell stout, spirals uneven, handsomely variegated vlack and

white or yellow and white, nodules in vertical rows of three

dots (Fig. 29). C. variabile Ads.

Note.—This shell has been called ertense Val., and even

placed as a variety of ferruginewm Say, which it does not re-

‘semble in the least. (See the original figure and description

of ferrugineum by Say.)

D. Long, narrow, yellowish-brown, spirals very irregular, three

vertical nodules united, forming vertical ribs, by far the rarest

form in Bermuda (Fig. 30). C. ferrugineum Say.

KE. Long, narrow, apex sharp, black with a white revolving band

below the suture, the black band contains dashes and the white

band dots, spirals regular, blackish inside (Fig. 31).

C. septenstriatum Say.

F. Larger than any of the above, spirals regular. A whitish

ealcarious deposit distinguishes this shell (Fig. 32). When

this covering is removed by acid or wear as in Fig. 33, it re-

veals a brownish interior with white bands on which the

nodules are shaped like an exclamation point (!), the two

upper dots being united. The apex is always very sharp.

GENERAL NOTES.

Mo.uusca ON Pike’s PEAK CoLorapo.—Last fall I collected

Pupa muscorum (L.), Vallonia cyeclophorella Ancey, Euconulus

Sulvus (Mull.) and Zonitoides arboreus (Say) by the printing office

on Pike’s Peak, 10,000 ft. alt. I put them on record because of the

altitude; the dominant vegetation of the place consists of Achillea,

Dasiphora, Fragaria, Salix, Rosa, Populus tremulotdes, Carduus,

Geranium, Epilobium, Delphinium, Arctostaphylos uva-ursi, Cam-

panula, Potentilla, Allium, Pedicularis, Gentiana, Picea, Pinus,

Juniperus, Antennaria, Artemisia, Pentstemon, Machaeranthera, Rud-

beckia, Frasera and Calochortus: nearly all circumpolar genera, it

will be observed, the last five only being exclusively American. I

have a note that I found also Sucetnea avara, but kept no specimens.

CHIONE CANCELLATA LINN. IN THE JERSEY City MARKET.—

A strange shell in the market always interests the conchologist. A

short time ago my brother gave me a Ohione cancellata which he had

found with some clams ( Venus mercenaria) purchased of Mr. Brittain,

a fish dealer on Bergen ave., Jersey City, N. J. He said there were

several in the basket from which the clams were taken. Desirous

of knowing whence they came, I inquired of Mr. Brittain where the

clams were gathered and he said he believed they came from North

Carolina.—SLoman Rous.

HELICOGONA ARBUSTORUM IN NEWFOUNDLAND.—Adult living

specimens of this common British and European land snail were col-

lected by Dr. Robert Bell in the middle of July, 1885, on grassy

slopes facing the sea, near the narrows of St. John’s Harbor, New-

foundland. So far as the writer is aware, this is the first time that

this species has been found, in a living state, on the American side

of the Atlantic. Dr..Bell says that many wrecks of vessels take

place on this part of the coast, and that a little farther to the south

of the locality where these snails were found, there is a small patch

where the common heather (Calluna vulgaris) grows. ‘This marks

the spot, he adds, where an emigrant ship was stranded, and the

beds of the emigrants, which were stuffed with heather, were taken

ashore and emptied out.—J. F. Wuireaves, in 7he Ottawa Natural-

ist, vol. xvii, no. 11, p. 192, Feb., 1904.

BaRBARA CHANNEL, CaLirornia. By William Healey Dall

(Proc. Biol. Soc., Wash., Dec. 13, 1903, pp. 171-176).

In this interesting paper Dr. Dall describes ten new west-coast

species. Of this number all, excepting A/tra dolorosa trom the Gulf

of California, were dredged at Santa Catalina Island during the

summer of 1903, by Messrs. Lowe and Paine. One genus, Macrom-

phalina, is new to the west coast. New species are: Act@on (Ric-

taxis) painer, Clathurella lowei, Mangelia fanchera, Mitra lowei, Mitra

dolorosa, Murex (Ocinebra?) painet, Lunatia draconis, Macromphalina

californica, Scala sawine and Ischnochiton biarcuatus. As will be

seen by the feminine endings two species are named for ladies. Be-

sides the species from the Gulf of California, Lunatia draconts has

been dredged at Drake’s Bay, Monterey and the Farallones Islands.

Of the specific name draconis Dr. Dall says: ‘‘ As Drake was long

known to the Spaniards as ‘ El Drako,’ I have named the species

draconis in his honor.’ Seala sawine has been dredged off the

Coronada Islands, Avalon and at the Isthmus. The type is from

the harbor side of the isthmus at Santa Catalina and was dredged by

Dr. Dall in 1875. With these exceptions all the species , were

dredged off Avalon. Another new species of a genus not before

known to inhabit the west coast was described by Dr. Dall in THE

Nautitus, Sept., 1908, under the title, «* A New Species of Metz-

geria.”” This species collected by J. H. Paine, Dr. Dall named

Metzgeria californica.—Mrs. M. Burton Williamson.

WALKER: ON SOMATOGYRUS.

THE NAUTILUS.

Vor. x VIT. APRIL, 1904. No. 12.

NEW SPECIES OF SOMATOGYRUS.

BY BRYANT WALKER.

Through the kindness of Mr. A. A. Hinkley, of Du Bois, Ill, I

have had the opportunity of examining the Amnicolide collected on

his recent trip to the Coosa river, and the larger portion of the

species herein described are from his collection. The others have

been received from the different sources stated in the descriptions.

The new species collected by Mr. Hinkley are remarkable for the

diversity of form exhibited, which was quite unexpected in view of

the very general similarity in that particular of the species already

discovered. The collection also shows that the earlier collectors on

the Coosa practically ignored the smaller forms in the more exciting

pursuit of the peculiar Pleuroceridae of the river, and that there yet

remains much to be done before the molluscan riches of that wonder-

ful stream will be exhausted.

The late Dr. Jas, Lewis in his ‘‘ Fresh Water and Land Shells”

(1876), lists four species of Somatogyrus as occurring in Alabama,

viz:

S. aureus Tryon. S. parvulus Tryon.

S. currierianus Lea. S. subglobosus Say.

Having Dr. Lewis’ collection in my possession, I am able to check

up his determinations in the light of our present information. It is

evident, from the condition of his specimens, many of which are not

even washed, to say nothing of having the black and ferruginous de-

posits removed, with which they are frequently covered, that Dr.

134 THE NAUTILUS.

Lewis had not given any critical study to the group, and that his

determinations were at the best superficial. It is of interest there-

fore to consider his list serzatim, and to make such corrections as are

necessary. SS. aureus. Dr. Lewis confounded this species with S.

parvulus Tryon and georgianus herein described. For the first error

he is not wholly responsible, as the only genuine parvulus he had

was received from Dr. Lea as aureus. His specimens from the

‘Tennessee River”’ and ‘‘ Cahawba River”’ are georgianus. Those

from the Coosa are partly georgianus and partly aureus. ‘Those from

the Alabama river are correctly named.

It may be added that aureus was found in the Coosa at Wetumpka

by Mr. Hinkley, where it has also been collected by Mr. A. C.

Billups. It is also in the Lewis collection from the Holston river,

Tenn., the Etowah river, Ga., the Tennessee river, Jackson Co.,

Ala., and from Bridgeport, Ala. It was also collected by Dr. Pils-

bry and myself in the Tennessee river at Knoxville, Tenn., on our

return from the Pentadelphian expedition in 1901. I have it also

from Decatur, Ala., collected by De Camp.

S. curriertanus, Dr. Lewis’ specimens from Decatur, Ala., are

labelled ‘‘ Type”? and seem to be correct. See Pl. v, figs. 8 and 9.

S. parvulus. As stated above, the only specimens referable to

this species (see Pl. v, figs. 22 and 23) from the Connesauga river,

Ga., were received from Dr. Lea under the name of aureus. His

specimens from the Tennessee river at Bridgeport, Ala., are imma-

ture aureus, as are also those from the Coosa.

S. subglobosus. There are no specimens under this name from the

Coosa river in the Lewis collection. Those from the Alabama river,

while differing somewhat in contour from the typical form of the

Ohio valley, seem substantially the same.

The characteristic feature of the Coosa river species of Somatogy-

rus is the heavy flat columellar callus, which usually quite obliterates

the umbilicus. This is present in nearly all the species. The

former connection of the Coosa with the Tennessee drainage is shown

by the occurrence of S. subglobosus, aureus and georgianus in both

systems and the narrow, rounded columellar callus in S. obtusus and

umbilicatus, which is characteristic of all the species of the Ohio and

Tennessee drainage, except S. georgianus and the’ form referred to

S. curriertianus by Tryon in Mon. F. W. Univ. Moll., p. 62, Pl. 17,

THE NAUTILUS. 135

All the figures are drawn on the same scale so that the relative

size of the different species is represented on the plate.

Somatogyrus hinkleyi n. sp. Pl. v, figs. 1 and 2.

Shell globose-conic, imperforate or with a mere chink at the um-

bilicus, light horn-colored, smooth, growth lines scarcely evident.

Spire elevated, apex obtuse. Whorls 4—44, those of the apex con-

vex, penultimate and body whorls more or less shouldered; suture

deeply impressed ; body whorl large, convex or in shouldered ex-

amples somewhat flattened at the periphery and obtusely angled

below. Aperture large, rounded above, somewhat flattened at the

base and decidedly angled at the junction of the lip with the base of

the columella and angular at the upper insertion of the lip; lip

simple, in aged examples somewhat thickened within. Columella

heavy, callused, flattened and nearly straight, callus thinner on-the

parietal wall. Alt. 43, diam. 33mm. Alt. 5, diam. 35 mm.

Coosa river at Wetumpka, Ala. (type locality), five miles above

Wetumpka, Wilsonville and Fort Williams’ Shoals. Also Talla-

poosa river at Tallassee, Ala.

_ This fine species was collected by Mr. Hinkley in considerable

numbers at all the localities above mentioned, except at Tallassee,

where only a single specimen was found. It occurred ‘on rocks in

swift water, generally on the under side. Sometimes several indi-

viduals were found close together.’”’ It differs from all the known

species in the elevated spire and conical form excepting S. pennsyl-

vanicus and virginicus herein described, but those species are much

smaller and decidedly different in contour. Young shells have the

whorls decidedly convex, the shoulder not appearing until after the

third whorl. The penultimate whorl shown in its entirety in half-

grown specimens is usually quite quadrate, owing to the shoulder and

flattening of the periphery. In mature specimens the shoulder tends

to become less evident and often entirely disappears. I take great

pleasure in naming this unusual form after its discoverer, Mr. A. A.

Hinkley, whose recent trip to the Coosa was so fruitful in novelties.

Somatogyrus constrictus n. sp. PI. v, fig. 3.

Shell small, conic, light horn-colored, smooth, except for the fine

growth lines. Apex eroded in all specimens seen, the portion re-

maining consisting only of the last 2-24 subcylindrical whorls, which

are very convex with a deeply-impressed suture, the body whorl is

somewhat inclined to be gibbous. Aperture small for the genus and

nearly round, obtusely angled above. Columella concave with a

heavy, flat callus, which extends unbroken between the extremities

of the lip leaving the umbilicus scarcely exposed. Lip simple, some-

what flattened along the basal portion and obtusely angled at its

junction with the columella. Alt. 3, diam. 24 mm.

Coosa river, five miles above Wetumpka, Ala. (type locality), also

at Wetumpka and near Wilsonville.

Only a few specimens of this species were found by Mr. Hinkley

at any of the above localities, ‘never more than one in the same

place, and always on the under side of rock in swift water.” Un-

fortunately all the specimens are badly eroded so that it is impossible

to give the apical characters. No young specimens that can be re-

ferred to the species were found. This species is remarkable for its

elevated. amnicoloid shape and deeply: constricted whorls, but the

heavy columellar callus reveals its generic affinities.

Somatogyrus nanus n. sp. PI. v, fig. 4.

Shell very small, imperforate, conic-globose, pale greenish-yellow,

smooth, shining. Spire very short and rapidly acuminating to the

sub-acute apex. Whorls 8, those of the spire but slightly convex,

separated by a shallow suture; the body very large, forming most of

the shell, convex, somewhat flattened toward the suture. Aperture

quite narrowly-angled above, widening and regularly-rounded below.

Columella concave, flattened, with a heavy callous, which entirely

covers the umbilicus and becomes thin and transparent on the pari-

etal wall. Alt. 22, diam. 24 mm.

Coosa river, five miles above Wetumpka, Ala. (type locality), also

at Wetumpka, Wilsonville and Fort Williams Shoals above Farmer,

Ala.

This little species is apparently the most abundant form in the

Coosa. It was ‘‘found in all places on rocks in swift water, scattered

or collected in bunches of any number up to 25 or 30.” It is well

characterized by its small size and the short, acute apex, which with

large body whorl and slightly-impressed suture, gives a peculiar

mamilliform shape to the shell. The shells are almost invariably

covered with a thin, greenish deposit, which under the microscope

appears to consist of innumerable, oval granules, closely but irregu-

larly agglutinated on the surface.

THE NAUTILUS. 13¢

Somatogyrus umbilicatus n. sp. Pl. v, fig. 5.

Shell small, globosely depressed, umbilicate, light greenisli-yellow,.

smooth, except for the fine, rather unequal, lines of growth. Spire

short, obtusely elevated. Whorls 34, those of the spire convex and

separated by a well-impressed suture; body whorl large, gibbously

convex, Aperture sub-circular, rather longer than broad, obtusely

angled above and slightly flattened along the basal margin. Colu-

mella concave, narrowly reflected; columellar callus, moderately

heavy, rounded, reflected over but not concealing the round, deep

umbilicus, thin and transparent on the parietal wall. Alt. 3, diam.

3 mm.

Coosa river at Wetumpka, Ala. (type locality), also at Fort Wil-

liams Shoals above Farmer, Ala.

This species is remarkable for its depressed, valvata-like form and

round, deep umbilicus, which readily differentiates it from all other

known species of the genus. It does not appear to be very abundant

at Wetumpka, and only a single example was collected at Fort Wil-

liams Shoals.

Somatogyrus coosaensis n. sp. PI. v, figs. 6 and 7.

Shell small, globose, imperforate, light yellow, smooth, with very

fine lines of growth. Spire very short, apex obtuse. Whorls 34,

rapidly increasing, those of the spire but slightly convex and sepa-

rated by a very shallow suture; body-whorl inflated, large and

convex. Aperture large, very oblique, expanded and well rounded

above, obliquely flattened at the base. Columella concave, with a

heavy, flat callus, which entirely covers the umbilicus, but rapidly

attenuates above the axis; parietal wall with a thin transparent

callus. Lip simple, the upper extremity projected along the body

whor! at its insertion, at which point it is abruptly curved in to meet

the parietal wall and rapidly drawn back below, forming a decided

angle where it unites with the base of the columella. Alt. 34, diam.

4mm.

Coosa river at Wetumpka, Ala. (type locality), also five miles

above Wetumpka, and at Fort Williams Shoals above Farmer, Ala.

Very abundant at the first two localities, but only a single specimen

was taken at the last. ‘This species is about the size of S. currier-

tanus (Figs. 8 and 9) to which it is closely related, but differs in the

less elevated spire, slightly impressed suture, regularly rounded body

138 THE NAUTILUS.

whorl, which is not shouldered as in that species, and in the decided

angle at the junction of the columella with the basal lip. The bright

honey-yellow color is eminently characteristic. It resembles young

specimens of S. crassus, but differs in the particulars stated in con-

nection with that species.

Somatogyrus obtusus n. sp. Pl. v, fig. 10.

Shell small, globular, narrowly umbilicate, greenish white, smooth,

shining. Spire very short, apex obtuse. Whorls 34, those of the

spire convex and slightly shouldered, separated by a well impressed

suture, body whorl large, globosely convex. Aperture subcircular,

rounded above, obtusely angulate below. Lip simple, meeting the

body whorl at nearly right angles at its insertion on the parietal

wall, expanded below and somewhat thickened within along the

basal margin. Columella concave, narrowly reflected: columellar

callus not very heavy, and rounded; parietal wall covered with a

thin transparent callus. Umbilicus distinct, narrow, somewhat con-

tracted by the reflected columellar lip. Alt. 3, diam. 3 mm.

Coosa river, just above the railroad bridge at Farmer, Ala.

Only eight examples of this distinct, little form were obtained, but

they are very uniform, varying only in size. SS. obtusus differs from

nearly all the Coosa river forms in the narrow, rounded columellar

callus and distinct umbilicus. In this respect it is allied to the

species of the Tennessee and Ohio drainage, grouping around S,

integer, but differs from them all in the obtuse apex, globular form

and the decided angle at the junction of the columella with the basal

lip.

Somatogyrus crassus n. sp. Pl. v, figs. 11 and 12.

Shell small, globose, very solid, imperforate, light greenish yellow,

smooth, lines of growth very fine. Spire short, apex obtuse.

Whorls about. 4, those of the spire slightly convex, suture well im-

pressed. Body whorl large, somewhat gibbous and swollen above.

Aperture large, rounded above, somewhat flattened basally and ob-

tusely angled at the junction of the lip with the columella. Lip

simple, thickened within, by a deposit of callus. Columella con-

cave, with a heavy, flat callus which extends from one extremity to

the lip of the other, and entirely covers the umbilicus. Alt. (apex

eroded) 4,25, diam. ‘4, 25 mm.

Coosa river at Wetumpka, Ala. iH Epe loalitg) also five miles

above Wetumpka.

THE NAUTILUS. 139

Only a single adult specimen was found. But quite a number of

half-grown individuals occurred. This species differs from all the

others known from the Coosa, except S. georgtanus, in the solid

shell, heavy columellar callus, thickened lip and in the inflation of

the upper part of the body whorl. In these respects it resembles S.

georgvanus, but differs in size and in being imperforate, lacking the

axial groove, less gibbous, and more globose. The apex is eroded in

all the specimens so that the exact number of whorls could not be

determined. ‘The immature shells are about the size of S. coosaensis

and somewhat resemble that species, but differ in the thicker shell,

color, smaller and more regularly rounded aperture, which is scarcely

angled at the base, the upper extremity of the lip is also less curved

in at its insertion.

Somatogyrus georgianus n. sp. Pl. v, fig..13.—

Shell globose, turbinate, perforate, thick, solid, light greenish-

yellow, smooth, except for fine growth lines. Spire short, obtuse.

Whorls about four, those of the spire convex with a well-impressed

suture, body-whorl large, very convex and inflated above. Aperture

large, obtusely-angled above and broadly-rounded below. Columella

concave with a very heavy, narrow callus, which extends to the

upper insertion of the lip and is adnate to the body whorl only at its

upper end, and below the narrow umbilicus is separated from the

body whorl by a deep axial groove. Lip simple, but thickened

within, its insertion on the parietal wall is below the periphery. Alt.

(apex eroded) 5, diam. 44 mm.

- Chattanooga river, Chattanooga Co., Ga. (type locality), also

Tennessee river, Cahawba river and Alabama river, Ala. (Lewis

Coll.).

A couple of indifferent specimens have been in my possession for

several years, which were found among some Pleuroceride collected

by R. E. Call. A larger suite in Mr. Hinkley’s collection from the

same source, and three lots from the Lewis collection have served to

confirm the distinctness of the form. This species resembles S. sar-

genti (pl. v, fig. 14) in the inflation of the upper part of the body

whorl, but differs in lacking the shoulder characteristic of that species

and in the peculiar formation of the columella, which is unlike that

of any other species except S. pumilus Con. and S. trothis Doh. It

also resembles S. crassus, but is larger, the body whorl more elong-

ated and more inflated above and has an entirely different form of

columellar lip. Dr. Pilsbry has kindly compared some of the Ten-

nessee river specimens with the unique type of Conrad’s pumilus, and

writes that while pumilus has the same peculiar axial groove, it is.

smaller (alt. 3.9, diam. 3 mm.), different in color and has the aperture

more oblique. Doherty’s species is smaller, about the size of S. in-

teger, and has the axial groove only slightly developed. The three

species, however, form a natural group more closely related to each

other than to the other species in the genus. Many of the specimens.

in the Lewis collection have the aperture rather more expanded

below than in the typical form.

This species is apparently ovoviviparous. In four out of fifteen

examples in the lot from the Tennessee river, young shells of about

25 whorls and about 14 mm. in height and breadth were found lodged

behind the opercula of the adults in various degrees of extrusion. In

two cases the young shells dropped out in the cleaning process, the:

outer edge of the operculum being forced out of its normal position

to allow the passage of the young. In the other two, the young are

further within the shell and the operculum is set in nearly its usual

position. An interesting monstrosity, which apparently belongs to.

this species, occurred in the lot from the Cahawba river. Nearly the

whole of the body whorl is encircled at the periphery by a strong

carina. It appears from beneath the upper insertion of the lip and

continues around the whorl about three-fourths of the circumference,

when it rapidly subsides and entirely disappears before the lip is.

reached. ‘There is no trace of it on the upper whorls that remain.

The axial groove is bounded on the inner side by a sharp angle, which

merges into the edge of the lip at the base.

Somatogyrus pennsylvanicus n. sp. Pl. v, figs. 15 and 16.

Shell small, obtusely conic, narrowly umbilicate, sometimes im-

perforate, light horn-color, smooth, with very fine growth-lines. Spire

elevated, apex obtuse. Whorls about 44, convex, slightly flattened

toward the suture, which is well impressed. Aperture ovate, less

than half the length of the shell, angled above and rounded below,

slightly flattened along the basal lip. Columella nearly straight with

a rather heavy, but narrow, rounded callus, which is thin and trans-

parent in the parietal wall. Umbilicus a mere chink or entirely

covered by the callus deposit. Lip simple, somewhat thickened

within, especially on the basal part. Alt. 33, diam. 25 mm,

THE NAUTILUS: 141

Columbia, Pa.

About thirty specimens of this amnicola-shaped species were in the

collection of the late Dr. G. A. Lothrop, labelled Amnieola decisa,

but unfortunately with no indication from whom they were obtained.

The large number of species from that locality in the collection would

indicate that Dr. Lothrop had been in correspondence with some col-

lector residing in that vicinity. At first sight, it would be taken for

an Amnicola, but the columellar callus is decisive on its generic posi-

tion, which is confirmed by the allied S. wirginicus and by Mr.

Hinkley’s discovery of a somewhat similar elevated form (S. Acnk-

leyi) in the Coosa. It is similar in shape to that form, but is smaller,

the whorls more rounded, the columellar callus is narrower and

rounded, and there is no decided angle at the junction of the basal

lip with the columella. In shape it resembles also somewhat S.

virginicus but differs in the particulars pointed out in connection with

that species.

Somatogyrus virginicus n. sp. Pl. v, figs. 17, 18 and 19.

Shell small, globosely conic, imperforate, light greenish-yellow,

smooth, shining, lines of growth very fine. Spire elevated, obtusely

conic. Whorls about 4, those of the spire convex, with a well-

impressed suture, body whorl subglobose, regularly convex. Aper-

ture ovate, angled above and broadly rounded below. Umbilical

region impressed, but covered by a rather broad, rounded columellar

callus which becomes thinner and transparent on the parietal wall.

Columella nearly straight. Lip thin and sharp. Alt. (fig. 18) 33,

diam.3mm. Alt. (fig. 17) 34, diam. 25 mm.

Barnard’s Ford, Rapidan R., Va. (W.J. Farrer Coll.)

This species in its elevated form resembles S. pennsylvanicus, and

the two with S. hinkleyi form a natural group quite distinct in shape

from all the other known species. It differs from the latter in its

smaller size, more convex body whorl and narrow, rounded colu-

mellar callus, and from the former in being somewhat larger, less

solid, more globose, thin lip, color and especially in the impressed

umbilical area, which is one of the most distinctive specific charac-

ters. Like many of the Amnicole, there are two forms represented

in the series, one being decidedly more slender than the other as

shown by the figures, otherwise they are entirely similar. This is

probably a sexual difference, but has not been observed in any other

species of this genus. |

142 THE NAUTILUS.

Somatogyrus pilsbryanus n. sp. Pl. v, figs. 20 and 21.

Shell small, gibbous-globose, scarcely perforate, rather thin, light

yellow-horn colored, smooth, lines of growth very fine. Spire short,

conic, obtuse. Whorls 34, those of the spire convex, separated by a

well-impressed suture, body whorl large, very convex, gibbous.

Aperture large, widely ovate, obtusely angled above and regularly

rounded below. Umbilical region impressed. Umbilicus a mere

chink. Columella concave, with a heavy, flat callus, which becomes

thin and transparent on the parietal wall. Alt. 3, diam. 3 mm.

' Tallapoosa river, Tallassee, Ala.

This is another of the new species discovered by Mr. Hinkley. It

occurred quite abundantly and is a well marked and distinct form.

It is related to S. parvulus, Tryon (Pl. v, figs. 22 and 23), in gen-

eral appearance, but differs in the wide, gibbous body whorl, more

obtuse apex and in the heavy, flat, columellar callus, S. parvulus

being more acutely conical, with the body whorl regularly rounded

and with a narrow, rounded, columellar callus. Dr. Pilsbry has

kindly compared it with the types of Tryon’s species and concurs in.

its specific distinctness. I take great pleasure in naming it after him.

A NEW SUBSPECIES OF POLYGYRA TRIDENTATA.

BY H. A. PILSBRY.

Polygyra tridentata discoidea n. subsp.

The shell is larger than tridentata, more depressed, the spire

usually nearly flat. Whorls 53, closely and sharply striate. Umbili-

cus more widely expanding at its opening, showing more of the pre-

ceding whorl. The aperture is more or less “ dished,”’ the parietal

tooth directed towards the upper lip-tooth, which while varying

somewhat in shape has a tendency to be rather wide and flat-topped.

The lower lip-tooth is more acute, both being strictly marginal.

During a recent visit, Mr. G. H. Clapp called my attention to the

form of P. tridentata found around Cincinnati, and widely known in

THE NAUTILUS. 1438

collections. A recent sending from Mr. L. E. Daniels of the same

race from a point further down the Ohio valley is made the occasion

for describing it. The subspecies seems to be a characteristic and

abundant form along the lower Ohio river, its range southwestward

as well as up the river still remaining to be ascertained.

It resembles the large P. tridentata complanata in shape, but is in-

variably sharply striate and does not reach so large a size.

DESCRIPTION OF TWO NEW TERTIARY FOSSILS.

BY CHARLES W. JOHNSON.

Canceliaria rapella n. sp.

Shell very fragile, spire but slightly elevated, depressed and ex-

cavated near the suture, with three and one-half whorls including the

protoconch, the latter smooth and consisting of one and one-half

whorls ; body whorl with about twenty-

five spiral ridges, those on the central

portion flattened and _ obsoletely

grooved, lines of growth prominent

and on the spire give the interstices

between the spirals a punctated ap-

pearance; columella with two promi-

nent folds and a slight umbilical

rimation. Length, 29 mm.

Miocene, Magnolia, Dauphin Co.,

North Carolina.

One specimen of this delicate shell

was found while cleaning the marl

from the interior of a large Busycon

maxima var. tritonis Conr., collected

by Mr. Joseph Willcox. It is related

to ©. venusta Tuomey and Holmes,

but the shell is much thinner, spire less elevated and excavated

near the suture. Type in the museum of the Wagner Free Insti-

tute of Science, Philadelphia.

Lnnearia? divaricata n. sp.

Shell very thin, compressed, nearly equilateral, umbones smooth,

Academy of Natural Sciences, Philadelphia (Acc. no. 9706).

This interesting specimen represents both valves intact, the matrix

filling the interior is quite hard and the shell so thin that an attempt

to develop the hinge would undoubtedly destroy the specimen. I

can therefore only refer it doubtfully to the genus Zinearia until

more material is obtained.

GENERAL NOTES.

OccCURRENCE OF ZINC IN FuLGurR.—In Sevence for January 29,

1904, P. 196, Mr. Harold C. Bradley, of Yale University, states

that : “ In the course of an investigation on the chemical physiology of

certain invertebrates, undertaken under the direction of Dr. Lafay-

ette B. Mendel, it was found that the ash of the hepatopancreas of

the large carnivorous gastropod Sycotypus canaliculatus contains an

element hitherto unobserved in such connection, namely zinc * * *

samples of ash from Sycotypus canaliculatus gave approximately

eleven per cent. and twelve per cent. respectively of ZnO.”

‘* At the same time qualitative examinations were made of speci-

mens dredged from various parts of Long Island Sound about New

Haven and in all cases zinc was found in large quantities in the ash

of Sycotypus and Fulgur carica * * * The significance of this

unique occurence of zinc in the economy of Sycotypus and Fulgur is

still to be determined, as is the nature of the combination in which

it exists. These points, together with the distribution of the element

in other marine forms about the Sound, are at present being in-

vestigated.”

THE Senior Epitor oF THe NAvrtILus is on a collecting trip

through Florida and Cuba. He will return the latter part of April.

TWO NEW SPECIES OF PLEUROTOMA FROM CALIFORNIA.

BY WILLIAM JAMES RAYMOND.

Subgenus Genota H. and A. Adams.

Section Dolichotoma Bellardi.

Pleurotoma ( Genota) stearnsiana, new species.

Shell broadly fusiform, spire acute, outline of spire moderately

convex; whorls eight and one-half, convex anteriorly, slightly con-

cave near the suture, the margin at the suture strongly appressed ;

suture distinct; aperture longer than the spire; color orange to cream,

a broad, spiral, brown band below the suture and nine or ten narrow,

clearly-defined bands on the last whorl, one or two of these also visible

on the spire, bands nearly as wide as the lighter interspaces; interior

of aperture yellowish, lighter within and spotted with brown on the

outer lip by the external bands; first two whorls smooth, later whorls

with numerous revolving threads, closely beaded on the spire by in-

cremental lines which follow the outline of the lip, threads not

beaded below the periphery of the last whorl, but roughened by the

growth-lines and somewhat coarser anteriorly; aperture rather

narrow; posterior sinus shallow, rounded; lip acute, produced below

the sinus, canal wide; pillar solid, somewhat curved, obliquely

truncate below. Operculum normal. Long. of shell 30.5, of aper-

ture and canal 17, of body-whorl 23 mm.; max. diam. 13. mm.

Divergence 50°. An extremely old specimen which shows a thick-

ening of the pillar like an obscure fold, measures: long. of shell 41.5,

2 THE NAUTILUS.

of aperture and canal 22.5, of body-whorl 29.5 mm.; max. diam.

18mm. Divergence 48°. This specimen was dead when collected.

University of California Marine Biological Laboratory, stations

55 and 67, off San Diego, 25 to 80 fathoms, sand and mud, bottom

temperature 50° F, Also dead specimens from stations 21 and 8,

Catalina Island, 30 to 40 fathoms, sand and mud, bottom temp. 51° F.

P. ( Genota) stearnsiana is at once separable from the forty or more

specimens of its nearest ally, P. carpenteriana, examined by the

writer. The former species is very uniform, although found in dif-

ferent localities. With the same number of whorls it is half as large

as P, carpenteriana-and is proportionately broader. ‘The average

ratio of length to diameter is 2.38 in five specimens of P. stearnsiana,

in five specimens of P. carpentertana it is 2.70. The spire is pro-

portionately shorter in the former species and the brown bands are

more conspicuous. P. carpenteriana has been found in the California

Pliocene and Pleistocene and seems to be the first in time of a closely

related group, embracing besides the two species already named, P.

tryoniana Gabb, Pleistocene and Recent, and P. coopert Arnold,

found thus far in the Pleistocene of San Pedro only. It gives me

great pleasure to dedicate the present species to Dr. Robert E. C.

Stearns, known to all students of West American conchology.

Section Antiplanes Dall.

Pleurotoma (Antiplanes) catalinae, new species.

Shell sinistral, thin, elongated, slender, whorls ten to eleven ;

color light, pinkish-brown, without bands, interior of aperture a

little lighter: upper whorls more or less chalky; nucleus smooth, in-

flated; later whorls convex, suture deeply impressed; sculptured by

fine incremental lines and on the last whorls a few obscure, spiral

striations, mostly below the periphery; anal fasciole traceable on the

spire as a flattened or obscurely grooved band ; aperture narrow ;

canal wide and short; pillar nearly straight, with a well-defined

callus, obliquely truncate below; outer lip produced, deeply emargin-

ate near the sutural margin of the whorl. Long. of shell 27, of

aperture and canal 10.5; max. diam. 7:6 mm. Divergence 20°.

Dredged in 125 fathoms, green mud, off Catalina Island, living, U.

C. M..B. L. Station 36; off Point Loma, San Diego, 50 fathoms,

Station 72 (a single, dead specimen); off Point Loma, 106 fathoms, —

green mud and sand, bottom temperature 47.9° F., Station 73.

THE NAUTILUS. 5

This attractive shell is much like a reversed P. (Antzplanes)

santarosana Dall, in color and sculpture, but the whorls are more

oblique besides being reversed, and the spire is even more slender

than in Dall’s species. P. ( Antiplanes) catalinae was found associa-

fed with: P. (Antiplanes) perversa Gabb, which is also sinistral.

The latter species is wider, has less rounded whorls and the color is

a darker brown with a light, spiral band, as stated by Gabb in his

original description. The two species are readily separated.

DESCRIPTIONS OF NEW JAPANESE LAND SHELLS.

BH. Ac eI LS BY AND Y¥. HIRASE.

Eulota ( Plectotropis) pannosa var. awashimana n. var.

This race is similar to #. pannosa in color, texture, sculpture and

the profuse peripheral fringe, but differs in being much smaller, pro-

portionally higher, with decidedly narrower umbilicus, which is not

enlarged at the opening, the base being almost angular around it.

Whorls 54, the last very shortly and slightly deflexed in front. It

is more robust and less depressed than #. deflera. Alt. 8, diam.

13 mm.

Awashima, Echigo. Types no. 86495, A. N. S. P., from no.

-1164 of Mr. Hirase’s collection.

Two species of Plectotropis have been described by A. Adams

from Awashima: #. setocincta and H. scabricula. The first meas-

ures about 12x6 mm., the altitude half the diameter, being therefore

more depressed than awashimana, in which the alt. is nearly two-

thirds the diam. A. scabricula is about 9x6 mm., with 64 whorls,

the last ‘“‘subangulate”’ peripherally. This species is therefore

smaller than awashimana, with more whorls and blunter ambitus.

Helix conella A. Ad., 1868, from “Tabu-Sima’”’ (not H. conella

Pfr., 1861), is probably a synonym of Plectotropis deflexra Pfr., from

the same island.

Eulota (Plectotropis) shikokuensis subdivesta v. subsp.

Shell more depressed than EH. shikokuensis, and smoother, the

oblong granules bearing no cuticular scales, the periphery without a

fringe. Whorls nearly 6, the last very shortly and abruptly de-

flexed in front. Umbilicus more broadly open. Alt. 7, diam. 16

mm., umbilicus 5 mm. wide.

Sodayama, Tosa. Types no, 84783, A. N.S. P., from no. 1022

of Mr. Hirase’s collection. |

#. s. var. hadaka (NavuTitus xvii, 105) is a much less depressed

form, measuring, alt. 9.5, diam. 16, umbilicus 4 mm. wide, and alt.

8, diam. 14 mm.

Eulota (Aegista) eminens n. sp.

Shell broadly and deeply umbilicate, low-trochiform, dull yellow-

ish-brown, finely striate, the last striz on the last whorl broken into

low granules, which when quite unworn bear short cuticular laminz

in places. Spire convex-conic. Whorls 63 to 7, slightly convex,

closely coiled, and very slowly widening, the last whorl obtusely

subangular at the periphery, and descending a little in front, very

convex beneath. Aperture very oblique, rounded, about one-fourth

of the circle excised at the parietal wall. Peristome thin, narrowly

expanded, reflexed below. Alt. 7.3, diam. 10.8, width of umbilicus

3 mm. )

Toba, Shima. Type no. 86493 A. N.S. P., from no. 590a of

Mr. Hirase’s collection.

This species belongs to the group of Aegista mimula, but differs

from all the known species by its elevated spire, higher than in any

other Japanese Aegista, and approaching the contour of the species

referred to the section Celorus.

Eulota (Aegista) mimula var. goniosoma n. var.

This race resembles m¢mula, trachyderma and mikuriyensis in the

rather small aperture with thin, expanded lip, subreflexed below, but

not thickened within. The spire is low conoid-convex, the periphery

strongly angular and the base convex, abruptly curving into the wide

umbilicus. The lusterless surface is brownish-yellow, freckled with

buff dots, finely, rather irregularly striate, and in some specimens re-

taining short, triangular cuticular lamine below the periphery.

Whorls 54 to d3. Alt. 6.5, diam. 11.3 to 12 mm., width of umbili-

cus 4 mm.

Amagisan, Izu. Types no. 86462 A. N.S. P., from no. 1165 of

Mr. Hirase’s collection.

On account of its strongly angular periphery, this might be con-

THE NAUTILUS. 5

sidered a distinct species, and it may prove to be so; but it belongs to

a group of forms which may for the present be ranked as subspecies

of #. mimula, and including the following :

E. mimula Pils.

E. mimula trachyderma Pils. & Gude. (#.-aperta trachyderma,

Proc. A. N. §., 1901, 614).

E. mimula mikuriyensis Pils. (2. aperta mikuriyensis, Naut.,

xvi, 49).

E. mimula goniosoma Pils. & Hir.

Punctum elachistum n. sp.

Shell umbilicate, depressed, brown, the first whorl whitish.

Whorls 22, the last one sculptured with rather widely spaced lamellze

and close spiral striz in the intervals, the spire nearly smooth. The

whorls enlarge rapidly, and the last one is somewhat compressed be-

low the periphery, which is rounded. The aperture is large, oblique

and rounded, about one-fourth of the circle excised by the preceding

whorls. Alt. 7, diam. 1.2 mm.

Yanagawa, Chikugo. Types no. 86492 A. N.S. P., from no

1159 of Mr. Hirase’s collection.

There are fewer whorls than in P. leptum, which is also a little

larger, and judging from the figures, more densely lamellose.

Punctum apertum n. sp.

Shell broadly umbilicate, depressed, thin, brownish-corneous,

sculptured with delicate, thread-like riblets, in large part cuticular.

Whorls 3, convex, parted by an impressed suture. Aperture ob-

lique, rounded, slightly more than one-fourth of the circle excised by

the preceding whorl ; peristome thin and simple. Alt. 7, diam. 2mm.

Nemuro, Nemuro. Types no, 86490 A. N.S. P., from no, 1156

of Mr. Hirase’s collection.

This little snail from the northeastern province of Yesso, is dis-

tinguished by its depressed form and wide, shallow umbilicus. —

Zonitoides chishimanus n. sp.

Shell openly umbilicate, whitish-corneous, thin; closely and deli-

cately rib-striate, densely and finely striate spirally between the

lamelle. Spire convex. Whorls nearly 34, convex, slowly increas-

ing, the last rounded peripherally and below. Aperture quite ob-

6 THE NAUTILUS.

lique, wide-lunate, the peristome simple and thin. Alt. .7, diam.

1.1 mm.

Kunashiri, Chisohima chain (Kuril Is.). Types no. 86491 A. N.

S. P., from no. 1155 of Mr. Hirase’s collection.

This very small, whitish species is more closely sculptured than

any Japanese Punctum, unless P. leptum Wester], be an exception.

That species from Nagasaki is larger and has a much narrower

umbilicus.

Macrochlamys chaunazx n. sp.

Shell perforate, convex-conic above, more convex below the

slightly obtusely angular periphery, the angle above the middle;

thin, somewhat transparent, pale yellow. Surface brilliantly glossy,

showing some slight growth-wrinkles and densely-crowded, very

minute spiral stria. Whorls 4, moderately convex, the last about

double the width of the preceding, subangular, the angle becoming

obsolete at the aperture. Aperture rather large, rounded-lunate,

Peristome simple and thin, reflexed at the columellar insertion. Alt. 7

2.7, diam. 4.5 mm. 3

Imotoshima, an islet south of the Hahajima, Ogasawara. Types

no. 83030 A. N.S. P., from no. 899 of Mr. Hirase’s collection.

Also found on Hahajima.

Macrochlamys cerasina shinanoensis n. subsp.

Shell resembling M. cerasina and M. gudei, but much larger than

the former, more globose and more glossy than the latter. There are

64 convex, very slowly widening whorls, the last one angular at the

periphery in front, becoming rounded on the latter part. Spire low

conic, with nearly straight outlines. Base strongly convex, impressed

around the narrow axial perforation, which is nearly concealed by

the triangular dilation ef the columellar lip. Alt. 10.4, diam. 7.4 mm. ~

Enasan, Shinano. Types no. 86483 A. N.S. P., from no. 1173

of Mr. Hirase’s collection.

Tornatellina monodonta n. sp.

Shell imperforate, ovate-conic, thin, pale yellowish corneous, im-

perfectly transparent, almost smooth. Spire straightly conic, the

apex obtuse. Whorls 43, moderately convex, the last somewhat

swollen. Aperture oblique, ovate, somewhat less than half the totai

length. Outer lip thin and simple, columella strongly twisted, form-

THE NAUTILUS. 7

ing a white spiral fold. No parietal lamella. Length 3, diam.

1.9 mm.

Imotojima, Ogasawara. Types no. 86479 A. N.S. P., from no.

1158 of Mr. Hirase’s collection.

This form is distinguished at once from others described from

Ogasawara-jima and the islands of Izu by the absence of a parietal

lamella. It occurs also on Hahajima, no. 1158a of Mr. Hirase’s

collection.

Carychium nipponense n. sp.

Shell oblong, with a rather wide spire and obtuse apex, clear,

transparent corneous, smooth and glossy. Whorls 4, convex, the

suture well impressed. Aperture oblong, oblique, with a single,

small, acute lamella at the middle of the inner margin, and a larger

tubercle opposite to it within the outer lip, which is thickened

throughout. Length 1.3, diam. .6 mm.

Sendai, Rikuzen. Types no. 86441 A. N.S. P., from no. 1157a

of Mr. Hirase’s collection. :

A dwarf among pygmies. It is like C. hachijoense in its polished

surface, but differs in the wide spire, not tapering regularly as in that

insular form. C. noduliferum, pessimum and borealis are all conspic-

uously striate. OC. noduliferum and C. nipponense are the only species

at present known from the main island of Japan. Specimens sent

from Uji- Yamada, Ise, indicate that C. nipponense has a wide range

along the ocean coast of Nippon.

Alyceus oshimanus n. sp.

Shell of the depressed low-conoid shape of other Japanese species,

the umbilicus oblong, the last whorl deviating tangentially about

half-way across the preceding. Whorls 33, the first two smooth,

reddish or yellowish, the following whorl rib-striate, at first finely

and closely, but on the first half of the last whorl the riblets become

quite widely spaced. Last half of the last whorl swollen, and very

much more finely and closely sculptured than any other part of the

shell; the neck rather strongly contracted, then swollen and sculp-

tured again. Aperture very oblique, circular, the lip strengthened

by an external rib, built forward beyond the rib, the upper and lower

margins arched forward a little. Alt. 2, diam. 4mm. Operculum

thin, yellow.

8 THE NAUTILUS.

Oshima, Osumi. Types no. 83385 A. N.S. P., from no. 931 of

Mr. Hirase’s collection.

This species differs from the allied A. vinctus in its sculptured ©

neck and less developed “ collar”’ or lip-rib. No land shell of the

important island of Oshima is known to be identical with species of

Kyushu or of the main island of Japan.

Stenothyra formosana n. sp.

Shell small, ovate, smooth and glossy, yellowish olivaceous. Spire

convex-conic, about 4 whorls remaining, the earlier ones being

eroded. Last whorl moderately inflated, distinctly compressed from

back to face, strongly contracting to the aperture, which is subverti-

cal, ovate, and not much exceeding one-third the length of the shell.

Jength 3.9, diam. 2.2 mm.

Kironten, Formosa. ‘Types no. 86485 A. N.S. P., from:no. 159

of Mr. Hirase’s collection. )

This small, plain species is related to a form in the collection of

the Academy labelled S. glabra A. Ad., but is very much larger,

and not quite so much contracted at the aperture. S. glabra was not

very fully defined by Adams. It was described from Peiho, but has

been reported from Formosa by Nevill, Handlist Ind. Mus., p. 43.

Melania hahajimana n. sp.

Shell rather thin and light, yellowish olive, usually with some in-

distinct reddish longitudinal streaks on the spire ; somewhat glossy,

sculptured with irregular, unequal but fine spiral grooves and striz,

which on the spire cut the longitudinal growth-wrinkles into oblong

beads, irregularly and unevenly developed. The spire is slender

with slightly concave outlines. Apex eroded, 6 or 7 remaining

whorls but slightly convex, separated by an impressed, oblique

suture. Last whorl inflated in the middle. Aperture ovate, ob-

lique, broadly rounded below, the thin lip slightly sinuous.

Length 34, diam. 10.5, length of aperture 10.56 mm.

Length 380, diam. 10, length of aperture 10.8 mm.

Hahajima, Ogasawara. Types no. 8645 A. N.S. P., from no.

172 of Mr. Hirase’s collection.

The slender spire, thin texture and inflated last whorl widely

separate this form from M. boninensis of Chichijima, the only Melan-

ian hitherto known from the Ogasawara-jima. It is related to M7.

THE NAUTILUS. 9

tuberculata (Miill.), a widely distributea Oriental form, much more

strongly sculptured, with more convex whorls.

M. boninensis Lea has been found to grow much larger than the

original examples, reaching a length of 32.5 mm.

Melania libertina var. gigas n. v.

Very large, finely striate spirally, more coarsely so at the base, but

without longitudinal folds. Olivaceous-brown, yellow in places, with

some darker-brown streaks; the color concealed by a black ferrous

coat. Length of decollate shells with about 4 to 44 whorls remain-

ing, 48 to 51, diam. 20 mm., Jength of aperture 21 to 22 mm.

Arato, Echizen. Types no. 86441 A. N.S. P., from no. 171 of

Mr. Hirase’s collection.

This is the largest Japanese Melanian now on record. Some spe-

cimens of MW. lébbeckiana are longer, but they are not so stout in

figure.

A SINGULAR EOCENE TURBINELLA.

BY WILLIAM HEALEY DALL.

A singular Turhinella has recently been received from Mr. 8. W.

McCallie, of Georgia, which seems to stand, to some extent, between

the two well known types, Zurbinella proper and Vasum.

Psilocochlis subg. nov.

Shell thick and heavy, with depressed dome-like spire and few

whorls, a strong siphonal fasciole surrounding a wide umbilical fun-

nel, which is completely filled by a heavy deposit of callus, which

also extends to the posterior angle of the aperture; the pillar exhib-

its three strong elevated plaits, and the surface is smooth or free from

ribs, nodules, or prominent sculpture of any kind. ‘Type:

Turbinella ( Psilocochlis) McCallie sp. nov.

Shell short and broad, with about four whorls, of which all but the

last are very small; apex hardly rising above the last whorl, which

is dome-shaped above and widest at about the level of the posterior

angle of the aperture, diminishing forward and slightly constricted

behind the strong and flaring siphonal fasciole ; umbilical funnel

smooth, but nearly filled with a smoothappressed mass of callus, con-

10 THE NAUTILUS.

tinuous over the body, and much thickened behind; pillar straight,

with three strong plaits, canal shallow, short; suture distinct, sur-

face smooth except for very fine incremental and revolving lines ;

outer lips broken, but apparently simple and sharp. Length 50,

max. breadth about 88 mm., diameter of umbilical funnel about

20 mm. . lis

Horizon : Claibornian Eocene of Richmond Co., Ga.

This singular shell has very much the aspect of Pyrula smithit

Lea (Lacinia alveata Conrad), Contr. to Geology, pl. v, fig. 162;

but has a lower spire, and is wider and rounder at the shoulder, be-

side having the strong plaits on the’ pillar which do not exist in

Lacinia. It will be illustrated in a forthcoming publication. Mean-

while collectors should be on the lookout for it.

NEW VARIETIES OF AMERICAN LIMNZAS.

BY FRANK COLLINS BAKER.

Limnea reflexa iowaensis var. nov.

Shell thin, with a short, dome-shaped spire; whorls 5—54, rather

flat-sided, loosely coiled; suture well marked but not profound ;

aperture with the characteristic turret of typical reflera, with a heavy

plait extending across the columellar callus ; spire and aperture of

equal length ; color dark horn, either plain or with spiral or longitu-

dinal zebra-like markings; aperture marked internally by several

longitudinal red bands, indicating the position of former peristomes ;

umbilicus covered.

Length 28.50, width 12.00, aperture length 13.50, width 7.00 mill.

Length 30.00, width 11.50, aperture length 15.00, width 7,00 mill.

Length 26.50, width 11.50, aperture length 14.00, width 7.50 mill.

Length 26.00, width 11.00, aperture length 12.00, width 6.00 mill.

This peculiar variety was found in a collection recenlty sent to the

writer for study, by Mr. Bryant Walker. It differs from all forms

of this species in having the spire and aperture of equal length, in

the peculiar dome-shaped spire and in the general robust appear-

ance.

In the Illinois and Michigan Canal, at Joliet, this variety is found

and shows a perfect gradation from the short, stumpy variety, with

THE NAUTILUS. 1}

‘spire and aperture of equal length, to. the long, spiral reflera. In

this lot one may trace the variation from dowaensis, through umbrosa

and jolietensis to typical reflera.

In a lot of shells received from Mr. Henry Hemphill, four speci-

mens were found which appear to belong here. Two specimens are

fairly typical, while two show a variation toward variety umbrosa.

They are from J.ake ele Lea, Minnesota. The types are from

Muscatine, Iowa.

_Limnea reflexa crystalensis nov. var.

Shell solid, with dome-shaped spire ; whorls 5—6, flatly rounded,

loosely coiled; sutures not impressed, but well marked; spire

of variable length, but typically about the length of the aper-

ture; aperture long-ovate, peristome with a heavy internal rib;

eolumeilar callus heavy, spreading over the inner lip and crossed by

a strong plait ; umbilical region showing a slight perforation beneath

the overhanging columellar callus; color light or dark horn, some

This variety may be collected in countless numbers at Crystal

Lake, Illinois. The lot from which this description was drawn num-

bers 105 specimens, and was collected by Dr. N. H. Lyon. This

variety bears the same relation to reflexa that variety michiganensis

Walker does to palustris, and its growth is probably governed by the

same physical conditions.

Limnea reflexa hemphilliana nov. var.

Shell rather solid; color light horn; dig 6, very flat-sided,

loosely coiled, nuclear whorls very dark red; sutures not impressed ;

spire acutely pyramidal, about as long as the aperture; aperture

elongate-ovate ; peristome thin, bordered internally by a red band;

columella oblique, with a rather heavy plait; parietal wall covered

by a spreading callus which almost closes the umbilicus; some speci-

mens show a tendency to become malleated.

Length 27.00; width 11.00; aperture length 14.00; width 7.25 mill.

Length 27.00; width 11.50; aperture length 15.00; width 7.50 mill.

Distribution: Lake Albert Lea, Minnesota.

Specimens of this very distinct variety were found in a lot of

shells received from Mr. Bryant Walker. They look like a widened-

out variety exi/is withashort spire. They have some relation to the

variety 2owaensis, but the spire is sharply conic, while in that variety

it is dome-shaped.

GENERAL NOTES.

Limax Maximus L. IN Catirornia.—The United States

National Museum has recently received several specimens of this.

species from Mr. §. A. Pease of San Bernardino, Cal. Mr. Pease

informs us that they were collected out of doors, near a house,

in Redlands, and that it was reported to him that they were

feeding upon flowers and plants. He also states that he has heard of

this same slug in different parts of San Bernardino county.

The specimens sent us are darker than the usual East American

form and not so large, the longest individual (preserved in formalin)

measuring 58. mm.—PauL BartTscu.

Notice oF Srx New Species or UN10S FROM THE LARAMIE

Grour.—By R. P. Whitfield (Bull. Amer. Mus. Nat. Hist., XIX,

1903, p. 483-487). U. esopiformis, verrucosiformis, retusoides

brownt, percorrugata and postbiplicata are described from Snow

Creek, on the Missouri River, about 130 miles N. W. of Miles City,

Montana. The names indicate the species of the recent fauna be- |

lieved to be related to these Laramie forms; but the radial V-like

beak-sculpture of at least part of them shows that there is nothing in

tlhe supposed relationship of the Laramie forms to any surviving

North American Unios. They belong to the Hyrtinez of Simpson’s

arrangement, and are only referable to Unio in a Lamarckian sense.

The name Unio brownt Whitf. being preoccupied, that species may

be called Parreysia barnumi. It is named for Mr. Barnum Brown,

who collected the series.—H. A. Pilsbry.

ser., ix 234, pl. 34, fig. 5, 1845). Dr. Dall (Trans. Wagner Free Inst.

Sci., iii, pt. iv, p. 813, 1898) suggests that this may possibly be the

same as Teredo calamus by the same author (op. cit., fig. 4) which

apparently differs only in size. ‘The position of 7. fistula has always

been questioned owing to the absence of all shell characters. Among

the above-mentioned material is a specimen having a total length of

58 mm. with valves about 12 mm. in length imbedded in the lower

end of the tube as shown in fig. 1. From this it will be seen that it

evidently belongs to the genus Teredina, although I have seen no

trace of the tube being separate, and the number of accessory valves

are poorly defined, the small, dorsal, triangular space having but a

slight median and transverse groove. ‘The valves are divided into

three areas by two faint radial lines which interrupt the concentric

lines as shown in fig. 2. On the anterior angle near the margin are

traces of a fine squamose imbrication over-riding the concentric lines.

A NEW SPECIES OF PLEUROTOMA FROM THE PLIOCENE OF CALIFORNIA.

BY WILLIAM JAMES RAYMOND.

Subgenus Genota H. and A. Adams, section Dolichotoma Bellardi.

Genota riversiana, new species. |

Shell narrowly fusiform, spire elevated, outline oa spire contained

within two straight lines; whorls slopingly shouldered, convex

anteriorly, slightly concave near the suture, an obtuse angle separat-

ing the wider convex area from the narrower concave area, whose

widths are in the ratio of five to four; posterior margin of the whorls

strongly appressed, suture distinct ; first two or three whorls broken

away, later whorls with conspicuous, elevated, revolving threads, of

which about eight below the shoulder and six above are more

prominent, those above somewhat finer and closer; between the pri-

mary threads are much finer, secondary threads; on the last whorl ~

about sixteen principal threads below the shoulder, coarser and more

widely spaced anteriorly, with one to three secondary threads

occupying each interspace ; axial sculpture consisting of sharp, ele-

vated growth lines, elegantly decussating the revolving threads,

THE NAUTILUS. 15

especially conspicuous just below the suture; on the uppermost of

the remaining whorls are faint nodes, about twenty to the whorl ;

aperture rather narrow; posterior sinus shallow, rounded; lip

slightly produced below the sinus, as shown by the growth lines ;

two-thirds of last whorl broken away; canal rather wide; pillar

solid, curved, a somewhat prominent, smooth swelling above ; body

whorl eroded in front of the aperture, with a wash of callus striated

in lines parallel to the lip.

Length of shell 59, of aperture and canal 30, of body whorl 41 ;

max. diam. 20.5 mm. Divergence 30°. These measurements are

taken from the broken shell. The spire was probably about 4 mm.

longer and the total length of the perfect shell could not have been

less than 75 mm., with 7 or 8 whorls. From the Pliocene of Santa

Monica, California.

Genota riversiana is the narrowest form of this subgenus found in

California. ~Only an occasional, greatly produced G. carpenteriana

Gabb can compare with it in this respect. ‘The narrow form, the

prominence of the revolving sculpture and the obtuse angle, behind

the middle of the whorls, well characterize this species. In G.

coopert Arnold and G. tryontana Gabb the angle is sharper and in

front of the middle of the whorls. The principal revolving threads

in the present species are more conspicuous and more nearly equal

than in G. cooper, of which a fine specimen from the Pleistocene of

Santa Monica is before the writer. The latter species is the most

sharply sculptured of those hitherto described. Form and sculpture

at once separate G’. riversiana from CG. carpentertana Gabb, and stiil

more widely from G. stearnstana Raymond, which is the shortest and

widest species of the subgenus.

It gives me great pleasure to dedicate this beautiful species to the

uiscoverer, Professor J. J. Rivers, who has made a large and most

interesting collection of the Pliocene and Pleistocene fossils found in

the vicinity of his home. ;

The list of subgenus G'enota will now be as follows:

of No.1. The others are well differentiated, yet closely related.

No. 1 is the most abundant in numbers; the others are apparently

rare.

NOTES ON EASTERN AMERICAN ANCYLI. II.

BY BRYANT WALKER.

In preparing my former paper on this subject (Naut., XVII, p.

13), I overlooked Hedley’s note on Ancylastrum (Proc, Mal. Soc.,

I, p. 118) in which he calls attention to the fact that Bourguignat’s

type was A. cumingianus and not A. fluviatilis. The latter species

being the type of the genus Ancylus, Ancylastrum, as used by Cles-

sin and those who have fol!owed him, was wholly unnecessary, being

equivalent to Ancylus s.s. ‘This rectification leaves the section re-

presented by A. fluviatilis and characterized by its elevated, capuli-

form shell, with the apex recurved and decidedly posterior, free, as

it should be, to be known as Ancylus s. s.

The division of the Eastern American species into two sections

distinguished by the character of the apex, was only a further step

in the direction pointed out by Clessin in establishing his section

Haldemania and, had his name been available, it would have been

used for one of them. Independent of the apical characters, Cles-

sin’s group was a valid one, and he was entirely justified in separ-

ating it from the Eurasion sections represented respectively by A.

fluviatilis and lacustris. And the fact that both of these species

have the apex radiately striate, does not at all militate against the

validity of Clessin’s Haldemania, nor of the two sections that have

been proposed to take its place. In order, however, that there may

_ be no confusion hereafter on this point, the description of the section,

which includes the Eastern American species with a striate apex,

may be amended to read as follows :

Section Ferrissia Walker.

Shell conical, ovate, oval or oblong, usually elevated ; apex acute

or somewhat obtuse, placed only slightly behind the middle of the

shell, and usually turned toward the right side, not recurved, radially

striate.

Type: A. rivularis Say.

Most of the species belonging to this section are by preference in-

THE NAUTILUS. LY

habitants of running water, and are usually found on stones, dead

shells, etc., in rivers and streams. The smaller, stronger and more

compact shell is no doubt the result of their environment. A few

species, however, of which A. parallelus is the most notable example

are to be found on plants or dead leaves in slow-flowing or stagnant

water. The distribution of the species seems to be more general

than that of the species of Lavapex.

I. Ancylus rivularis Say (1819). Pl. I, figs. 1-10 and 13-15.

This was the first species of American Ancylus to be described and

the meagerness of the original description is probably to be attributed

to this fact. But one dimension is given and nothing whatever is

said in regard to the contour of the shell. It was not until A. tardus

was differentiated in 1840, that any information was given on the

latter subject and then only by inference. The consequent doubt as

to what form was really intended to be covered by the description

was recognized at an early date. The characteristic difference in

the position of the apex and the shape of the shell was first pointed

out by Adams (Thomp. Hist. of Vt., p. 164, 1842), and his remarks

on the prevalent uncertainty in regard to Say’s species are quoted

with approval by Haldeman. It was not until the latter in his mon-

ograph supplied an accurate description and a good figure, that the

species can really be said to have been established. I am inclined

to agree with Haldeman rather than Tryon in considering Gould’s

rivularis (Invert. of Mass., p. 224), to be parallelus rather than Say’s

species.

Taking Haldeman’s description as the typical expression of the

species, A. rzvularis is a well-marked form, which typically is easily

differentiated from all other recognized species. It has a general

distribution through the Northern States from New England to

Nebraska and southerly to Virginia and through the Ohio and Mis-

sissippi Valleys southwest at least as far as New Mexico. I have

not seen it, however, from any of the southern Atlantic or the Gulf

States east of the Mississippi. It is subject to considerable variation,

however, in size and contour, and it is not always easy to differentiate

it from the western form of A. tardus. It is not likely to be mis-

taken for any of the other eastern American species, except perhaps

A. haldemani, which differs in the particulars stated under that

species.

(To be continued.)

18 THE NAUTILUS.

A DREDGING TRIP TO SANTA CATALINA ISLAND.

H. N. LOWE.

Last October it was the writer’s good fortune to spend a week at

Avalon, Santa Catalina Island. :

A small dredging outfit was included among the baggage. The

same dredge had five years ago brought up Fusus ropert Dall and

Turbonilla lowet Dall and previous to that had been used with such

good results by the late Edward W. Roper off Eastport, Maine and

with what results it was now used the following list will show. As

there were numerous small power launches at anchor in the bay, I

decided to venture the price of a day’s use of a launch and see what

strange creatures live in old ocean ‘‘a hundred fathoms deep.”

I invited to go along as a traveling companion, my young friend,

John Paine, for whom at my request Dr. Dall has named two of the

new species dredged.

The morning selected was clear and bright and the water smooth

as glass as we steamed up the island till just off “‘ Moonstone Beach ”

and under the lee of ‘“‘ Long Point.’’ Here we decided to make our

first haul in some 30 fathoms of water.

The water was so transparently blue that we could see our dredge

as it sank down, down into the realms of Mermaids and sea-serpents.

Anyone who has done any dredging well knows we did not take

along any rocking chair or wear our Sunday clothes.

After the dredge had been down a reasonable length of time we

commenced hauling in our thousand feet of dripping rope, by no

means an easy task. Almost every haul would be different, some-

times the dredge would be entirely filled with soft mud or sand,

again with broken shells, and twice it came up filled with small stones

to which beautiful bunches of Brachiopods were attached.

The second day we dredged in.somewhat deeper water up to fifty

fathoms with very good results.

After my return it took every evening for over three weeks to sort

over the dredgings with the aid of a strong lens.

Dr. Dall has kindly worked up the doubtful material PP described

the new species, in the Proceedings of the Biological Society of

Washington, Dec. 13, 1903, pp. 171-176.

NOTES ON A FEW SHELLS,

BY C. F. ANCEY.

Prof. H. A. Pilsbry has described and figured a few years ago

.(Proc. Acad. Nat. Sciences, Phila., 1901, p. 632, pl. xxxvi, fig.

30-41) a Japanese Clausilia which he called CZ. oseartana, in honor

of Dr. Oscar Boettger, the well-known German writer on Clausiliz.

He was probably unaware that a Chinese species of this genus re-

ceived the same name from P. V. Gredler (Zur Conchylien-Fauna

yon China. xvii Stiick, Wien, 1892, p. 8), who, curiously enough,

has dedicated his species to Dr. O. von Mollendorff whose Christian

name is Otto not Oscar. At all events, the name Oscartana cannot

stand for the Japanese Clausilia, this homonym having several years

of priority. Hence, I propose to substitute for it the name Clausilia

pilsbryana Anc.

I must also call attention to Claus. oscari Thiesse (Bttg., Proc.

Zodl. Soc. 1883, p. 34, fig. 16) a somewhat distinct form of CZ.

schuchi, v. Voith, perhaps entitled to specific rank, though Dr. West-

erlund (Fauna der in der Palaarktischen region lebenden Binnen-

Conchylien, iv, p. 140) calls this a variety of Cl. schuchi.

Terebra histrio Desh., was described (Journ. de Conch. 1857, pl.

iv, fig. 11) without a locality, from a specimen in Deshayes’ collection.

I have procured a fine specimen collected on the coast of Senegal to-

gether with 7. bitorqguata Desh., already known as West African,

Drillia rosacea Reeve, Marginella petiti Duval, M. goodalli Sow., M7.

eleryi, Petit. My example, consisting of 16 whorls, is 42 mill. long

and 10 mill. wide. For the identification I am indebted to Mr. Ph.

Dautzenberg. |

Natica prietoi Hidalgo (Journ. Conch. xxi, p. 332, Moll. Esp., pl.

20B, figs. 2-3), a very rare shell, discovered on the coast of Southern

Spain, was found again by myself at Algiers. I secured a large,

somewhat worn example and a smaller one very perfect. With this

I detected a specimen of another scarce species worthy of record, viz.,

Scalaria candidissima, Monterosato.

22 THE NAUTILUS.

Drymeus nubilus Preston, of which I have purchased a specimen

from the.author, who described it in the *‘ Journal of Malacology,”

vol. x, no. 1, March 1903, appears to be absolutely the same as

Drymeus recluzianus Pfr., var. martensianus Pils., from Costa Rica,

which of course has the priority.

Helicina pterophora Sykes (Proc. Malac. Soc. of London, vol. v,

no. 1, 1902, p. 20, fig.), from Guatemala, appears not to differ

essentially from H. oxyrhyncha Crosse and Debeaux, from unknown

locality. The shells labelled oxyrhyncha in the collection of the

British Museum, from Bonacca Island, Honduras, are hardly refer-

able to this species, hence, I suppose that Mr. Sykes has been mis-

led in considering his species pterophora as distinct from the true

oxyrhyncha, An example of the latter in my collection is quite

typical, lacking the colored bands of pterophora and uniform yellow.

NOTES AND NEWS.

SNAILS AND SLuGs IN THE NEw INTERNATIONAL ENCYCLO-

p#DIA.—In The Dial (Chicago) of Nov. 16, 1904, I took occasion

to set forth the character of some of the articles on scientific subjects

found in the most recent Encyclopedias. ‘The article ‘slug ”’ was

examined in a number of them, with interesting results. I said,

however, ‘‘ the ‘ New International’ and the ‘ Encyclopedia Amer-

icana’ have not yet reached the letter S, so we cannot tell what sur-

prises they have in store for us.”” The former of these has now come

to S, and to-day I turned with interest to ‘ slug.”” The common

Agriolimax campestris appears as ‘‘ Lima campestris” though one

would think a campestrian Zima might find it difficult to exist! We

are also told that slugs are ‘ vegetable eaters,” without qualification.

Turning over the article “snail,” I find a colored plate of American

snails. The generic nomenclature is almost pre-historic, ‘‘ Heli”

covering three different famiiies, not to speak of genera. Thus we

have Helix fuliginosa, Helix alternata, ete. We also have Bulimus

dealbatus and Bulimus fasciatus.

Now all this is stupid enough, and it seems fitting for those who

THE NAUTILUS. 23

know better to agitate the matter sufficiently to bring about a reform,

if that is possible-—T. D. A. CocKERELL.

A New Co.vectTor IN THE FiELp.—A few days ago I noticed

in my garden, where a Chipmunk ( Zamvas striatus Linne.) had been

** cleaning house ”’ for the spring, the only refuse he had brought out

was about a pint of empty shells, consisting of two species, about an

equal number each, Polygyra monodon Rack. and Succinea avara

Say. With the Polygyras the upper half of the shells were eaten

away and then nicely cleaned of the animal, the Succineas all

had the animal cleanly taken out without breaking the frail shell in

the least. The Succineas are every season very plenty within fifty

feet of Mr. Chipmunk’s abode, and the P. monodon is the predomin-

ating species of the genus in this locality, Des Moines, lowa.—T.

Van Hynine. |

Messrs. Walker, Clapp and Henderson have made a short collect-

ing trip in the Blue Ridge of Virginia. They report a small catch.

ADDITIONAL Notes on Limax Maximus L. IN CALIFoRNIA.—

It may be appropriate to add to Mr. Bartsch’s note on the occurence

of Limax maximus L. in California, that the Academy of Natural

Sciences of Philadelphia has received this species from the following

additional places in that state: Oakland, collected by Messrs. Williard

Wood and F. L. Button in 1896; Los Angeles, Dr. R. E. C.

Stearns, collected April 9, 1901; Monterey Co., Mr. Geo. H. Clapp;

San Jose, collected by Mr. O. P. Jenkins in 1902; and also from

Pasadena, Oct. 1896 and Long Beach in 1899, collected by Mr. H.

N. Lowe.—E. G. VanatTra.

Note oN VENUS ARAKANA Nevill.—In the Proceedings of the

Malacological Society for Oct., 1903, Mr. Smith has correctly re-

ferred Venus malonei Vanatta to Nevill’s species, but at the same

time he has added a new name to the synonymy by calling it

V. ‘‘ arakanensis.’”’ The brothers Nevill did not describe this shell —

as ‘‘ Venus ( Timoclea) arakunensis,’”’ as quoted by Mr. Smith. They

24 THE NAUTILUS.

called it ‘ Cryptogramma arakana.”’ The correct form is used by

Sowerby, on p. 83 of his Supplement to Marine Shells of South

Africa. —H. A. PILssry.

A DistortED OystTerR.—The most curious distortion that I have

seen was handed to me by a parishioner a few days ago. The species

is the common oyster taken from the Sound here (Branford, Conn.)

The earlier growth is 44 inches long, 14 inches wide, the shell then

shoots off to the right at an angle of 100° and continues 24 inches

with a width of 2 inches. It next turns to the left at an angle of

120° and adds 2 inches more. This is the external appearance—

Owing to the fact that in each case the animal abandoned a part of

the shell and built from the middle, the internal appearance is a

double curve.-—HeEnry W. WINKLEY.

WALKER: ON ANCYLUS.

THE NAUTILUS.

Von. XVIII. JULY, 1904. No 3.

NOTES ON EASTERN AMERICAN ANCYLI. Ii.

BY BRYANT WALKER.

Ancylus rivularis Say. Pl. I, figs. 1-10, 13-15.

The typical form as established by Haldeman is represented by

fig. 3 (the specimen figured agreeing almost exactly with his dimen-

sions), and is an ovate, moderately elevated shell with a subacute

apex, which is inclined toward the right side, and with about one-

third of the shell posterior to it. The anterior and dextral slopes

are regularly but not strongly convex ; the posterior slope is quite

concave immediately below the apex, but becomes nearly straight

toward the peritreme; the left slope is.nearly straight, sometimes

slightly concave towards the apex. The lines of growth are well

marked but quite irregular, and there is more or less of a tendency

to the radial rippling on the anterior slope so common in many

species. The shell is distinctly narrowed toward the posterior ex-

tremity, the greatest width being just in front of the apex. Asso-

ciated with the specimen figured, and grading into it, is a more

depressed form, with the apex less prominent and the posterior slope

nearly straight (fig. 4). Similar examples have been supplied from

several localities in the neighborhood of Buffalo, N. Y., and indeed

it seems to be rather the characteristic form of that region. The few

examples seen from eastern Massachusetts are smaller and rather

more depressed than the typical form.* Western specimens appar-

xiii, p. 105) should, I think, be referred to A. parellelus.

ently average larger than those from the Eastern States. The

largest examined are from Lincoln, Neb., one of which is represented

by fig. 6, which has the apex more obtuse than others from the same

lot. A series submitted by Dr. Sterki, from Ohio, are uniformly of

medium size, none of them attaining the dimensions of specimens

from Michigan and further west. Fig. 9 represents another western

form, larger, proportionately higher and with the anterior slope more

convex than in the typical form, and which in the longitudinal out-

line approaches the western form of tardus, and not infrequently is

very difficult to differentiate from it, while fig. 13 represents an

extreme form, unusually high, with nearly straight lateral slopes and

a very acute apex.

“While as.a rule it is not difficult to separate this species from

tardus, and on the whole the two species seem sufficiently distinct,

it is by no means always easy to decide in regard to individual cases

or even large series. This has been particularly true in regard to

the series from Ohio, received from Dr. Sterki, in which the two

forms seem to run together almost inextricably. As shown by the

figures given of each species, none of several distinctive characters

relied on are invariable, the posterior slope is frequently quite as

concave in taurdus as in rivularis, while the convexity of the anterior

slope is not uncommonly quite as great in the one as in the other, —

and neither the position of the apex nor the outline of the peritreme

is an absolutely invariable character. The most that can be said is,

that while typically the two forms are quite distinct, and in the main

can be readily distinguished, nevertheless the variation is so great

that, as is often the case with all the fresh-water groups, the sup-

posed specific characters fail to give an infallible basis for determi-

nation, and the decision in such cases must be the result of the indi-

vidual opinion of the observer based upon his general conception of

the species as applied to the particular specimens in question.

Taking this species as a whole, it may be said to be distinguished

from tardus by larger size, more depressed form, more acute apex,

which is more inclined toward the right side, and nearer the centre

(longitudinal) of the shell, the posterior slope is proportionately

longer and more oblique, the anterior slope is usually not so convex,

the left slope is usually longer and more convex than the right, the

shell is usually decidedly wider anteriorly and the transverse section

is wider in proportion to its height, and the side lines consequently

THE NAUTILUS. 27

more oblique. This last specification is perhaps a more reliable dis-

tinction in doubtful cases than any of the others. Occasionally

depressed specimens occur in which both of the side slopes are de-

cidedly concave, and the apex quite papilliform, This form, how-

ever, seems to be an individual rather than a racial peculiarity.

II. Ancylus tardus Say (1840). Pl. I, figs. 11, 12, 16-23. PI.

LF, fies. I-22: ;

Say differentiated this species from his rivular’s on three grounds :

1. The apex inclined backwards, but not laterally.

2. The straight posterior slope.

3. The oval aperture, not distinctly narrowed at one end.

His type came from the Wabash. But two dimensions are given,

length ,3,, breadth #5 in. (3.75 x 2.5 mm.). Binney errs in quot-

ing the length as 4.25 mm. He also states that the type is in the

collection of the Philadelphia Academy. Among the Ancyli’ re-

ceived from the Academy is a single specimen (No. 58045) labelled

** Wabash River, Mrs. L. W. Say,”’ which is undoubtedly the speci-

men referred to. As shown by the figure (PI, IJ, fig. 1), the pos-

terior margin is somewhat broken. Its present dimensions are

exactly those given by Say (3.75 x 2.5). It is a dead, somewhat

worn, shell, and the defective peritreme might easily have escaped

observation. When perfect, it must have been somewhat larger.

Adams (Thompson’s Hist. of Vt., 1842), was next to recognize

the species, which he says differs from rivularts in the position of

the apex and shape of the aperture. His dimensions (6.25 x 4 x 3.25

mm.) indicate a much larger shell, proportionately a little wider and

very much higher than the type.

28 THE NAUTILUS.

Haldeman’s descriptions (Mon., 1842), though short, when read

in connection with his description of rivularis, clearly differentiate

the form indicated. His figure was evidently drawn from the broad

form found in eastern Pennsylvania, and which justifies his remark

that tardus is proportionately broader than r7vudaris, when understood

as applying to the outline of the peritreme and not to the transverse

section. His dimensions, however, are quoted from Adams.

Neither Binney, Tryon nor Clessin, have added anything to our

knowledge of this species.

I have not been able to find a specimen that agrees either actually

or proportionately with the dimensions given by Adams, which indi-

cate a large, narrow and very high form. Western specimens of the

same length are uniformly wider and lower. The only Vermont.

specimens seen are a pair in the collection of the Philadelphia Acad-

emy labeled “* Vermont,” and a small suite of immature examples

from Hartland (No. 58036) (pl. I1., fig. 7). The former are quite

typical in their longitudinal and transverse outlines, but are very

wide, almost sub-circular in shape (4.5 x 3.5 and 4.25 x 3). The lat-

ter are similar, but- more depressed. Similar specimens, interme-

diate in elevation (pl. II., fig. 4), have been found at Orono and in

the Aroostook River in Maine. In all these the posterior slope is

straight. An elevated form (pl. II., fig. 10) similar to the Vermont

shells occurs at Silver Spring and Columbia, Pa., and is very like

that figured by Haldeman; the posterior slope, however, is more

oblique, and in some examples noticeably concave (pl. II., fig. 12).

All these shells, however, are alike in the comparatively small size

and great width, and should a larger suite show that this is the prev-

alent eastern form of the species it should probably be distinguished

varietally. The western, and no doubt the typical, form is quite

different. Larger, narrower and higher, it is typically a well-marked

form. The resemblance between Say’s type (pl. II., fig. 1) and the

upper half of fig. 20, pl. II., is very striking, and I have no doubt

but that Say’s specimen is an immattire example of this common

western species, which is found abundantly from Ohio west to the

Mississippi Valley. It is, however, quite variable, as shown by the

figures, and, as already stated, at times very difficult to differentiate

from the equally variable forms of rivularis. The typical western

form is represented by figs. 17 and 20, pl. II., and is characterized

by its regularly oval outline, elevated obtuse apex, which ‘is scarcely

THE NAUTILUS. 29

turned from the median line, and steep, nearly straight lateral slopes.

The anterior slope is usually more decidedly convex than in rivularis,

and the posterior slope, though frequently quite concave, is shorter,

more direct and less oblique than in that species. The variations in

contour leading towards rivularis are shown by figs. 11, 16, 18, 20

and 22 on plate I.

An unusually narrow form (pl. II., fig. 14)

occurred sparingly among the material supplied by Dr. Sterki.

A NEW OMPHALINA FROM ALABAMA.

BY GEO. H. CLAPP.

Omphalina pilsbryi n. sp. :

Shell about the size and general contour of O. fuliginosa ; umbili- |

cate, color rich reddish-chestnut with a dull satiny luster above,

smoother and more polished below. Striz of growth fine and close,

crossed by microscopic granules in spiral series like beads, giving

the upper surface a dull luster; below the granules are obsolete and

the surface polished. Apex smooth, and in all adult specimens seen

denuded of the epidermis. Whorls 54, rather flattened and slowly

increasing, the last whorl very much wider, more than double the

width of the preceding one, almost round, no flattening on the base.

Aperture oblique, circular. No thickening at the lip, which is

darker than the balance of the shell.

Greater diameter 27, lesser 234, altitude 174 mm. Oblique

height of aperture 14, width 14 mm.

Greater diam. 24, lesser 21, alt. 14:5 mm.

On hillsides in woods around Wetumpka, Ala. Collected by

Herbert H. Smith.

From above this shell has much the appearance of the large granu-

lated variety of O. /evigata found with it, but it lacks the close ribs

of that species, and the embryonic whorls are smooth, while in

levigata they are sharply ribbed. On the base the resemblance is

less striking, as levigata has a very small umbilicus, the base is

flattened, and the internal white thickening makes the base several

shades lighter than the upper surface.

This is one of the finest of the Omphalinas, and while it is quite

common around Wetumpka, it appears to have been entirely over-

looked by collectors. I take great pleasure in naming it after Dr.

H. A. Pilsbry, who is doing so much to clear up the dark places in

American Conchology. ‘Type in my collection, and cotypes in the col-

lections of the Academy of Natural Sciences, National Museum, etc.

THE NAUTILUS.

A MOLLUSCAN STAMPEDE.

BY T. VAN HYNING.

In the summer of 1899, while collecting shells in the vicinity of

Des Moines, Iowa, I made an observation which has seemed to me

to be of more than ordinary interest. Along the margin of a bayou,

adjacent to the Des Moines river, I discovered what was quite ap-

parently an old, abandoned cray-fish hole beside an old stump. Clear,

cold spring water was bubbling up from within the hole, overflowing

and running down the slope about ten feet to the bayou. | All the

way up the little stream, from the bayou to the hole, Physa gyrina

was very numerous and in all stages of development, from very

minute young ones up to well-developed adults. , All were leaded up-

stream and moving slowly towards the hole. Around the margin of

the hole, and down in it as far as I investigated, about fourteen

inches, the surface or wall of the hole was covered with them one

layer deep as tightly as they could possibly be crowded together, all

headed downward. All in the hole were adult specimens. The

lateral ones had wedged themselves in underneath the ones forward

of them until they were seemingly forced to the bottom of the hole,

and there became an immovable mass, as there would be no other

way of escape but to back out, which the lateral ones were not in-

clined to do, but on the other hand were anxious to go ahead. With

the water bubbling up through the space left in the center of the

hole, the shells had become very smooth and shining. With a stick

I dug down about fourteen inches and gathered about a pint of shells

from the walls, and a great number fell down the hole. I do not

know how much further it extended as it filled with dirt and shells

from my interruption. About a month later I returned to get some

of the water for analysis, but it had ceased to flow and dried up ;

recently dead shells were very plenty all around. I scraped up a

cigar-box full more of them. My impression would be that the

water, either from its cool temperature or some appetizing ingredient,

was the attraction. I have been sorry ever since that I did not give

it more thought at the time. The figure in the upper right-hand |

corner, while not artistic, serves to show the manner in which the

shells were adhering to the walls of the hole; the density of the

mass is not over-illustrated in the least, if any difference they were

even more tightly arranged. than illustrated ; there was not a space

in which a shell could possibly move.

DESCRIPTIONS OF NEW JAPANESE LAND SNAILS.

BY H. A. PILSBRY AND Y. HIRASE.

Eulota (Huhadra) irrediviva n. sp.

Shell umbilicate, resembling #. mercatoria, but very much more

depressed. Sculpture of fine growth-lines, minute scattered papilla,

and densely crowded, very fine spiral striw; the surface rather

glossy. The specimens are fossil and have lost color except a dull

reddish band above the periphery and sometimes another below it.

Whorls 5, the apical one rather large, the last whorl double the

width of the preceding, slightly subangular in front, only a trifle de-

scending to the aperture. The aperture is oblique, wide and low,

the upper and basal margins subparallel; lip reflexed and recurved,

the basal lip noticeably straightened. Alt. 21, diam. 86 mm.

Shell openly umbilicate, depressed with convexly conic spire, thin

but rather strong, reddish brown, the spire a little paler. Surface

dull, densely covered with minute short scales or the papillex left

after the loss of scales.. Whorls 7 to 74, convex, very closely coiled,

the last descending a trifle in front, barely perceptibly angular in

front, elsewhere rounded, especially beneath. The aperture is rather

small, oblique, lunate, the narrowly expanded and slightly thickened

lip forming about three-fourths of a circle.

Alt. 14.8, diam. 21, width of umbilicus 5 mm.

This is quite a distinct form by its thin lip and minutely lamellose

cuticle.

The four Aegistas described above would probably be treated as

species by many Helicologists, but their relationships are, we think,

better shown by connecting them with the allied forms.

LIMAX MAXIMUS AND OTHER SLUGS IN CALIFORNIA.

BY ROBERT E. C. STEARNS.

The occurrence of Limax maximus at Redlands, as reported by

Mr. Bartsch in the May number of the NauTILUs, carries this form

farther inland and to a higher altitude than heretofore known on the

THE NAUTILUS. : eee

West coast, at least in California, the general locality being over

fifty miles from the sea, and the elevation over 1300 feet or more.

Mr. Bartsch remarks that his specimens were ‘“‘ darker than the

usual East American form, and not so large, the longest individual

(preserved in formalin) measuring 58 mm.’’ This slug is said to

occur *‘ in different parts of San Bernardino county.”

In point of size, examples 75 mm. or more are not infrequent.

Dr. Pilsbry, commenting on specimens sent to him a year or two ago,

said “that it was not the common form, but a melanistic variety

which I have never seen from the East.’’ Hereabout there is con-

siderable variation in this respect ; occasionally individuals are met

with that are much darker than any of those sent to him at that time.

In some places this slug has already become a pest. In my

grounds I have not found that it does any material damage to flow-

ers or plants, quite unlike Helix aspersa in this matter. It seems to’

prefer the vicinity of the garbage can, which it exploits after dark,

being nocturnal in its wanderings, concealing itself in cool, damp,

dark or well-shaded places during the day. A greasy, cast-away

soup-bone is apparently to its liking, judging by the numerous slime-

tracks centering around such an object. It frequently invades human

habitations, directing its visits to the pantry. It is surprising how

small a hole or narrow crack even the largest individuals can pass

through. In order to keep them out, especially of the pantry

and porches, ordinary table salt in liberal quantities strewn around

and close to the threshhold, inside and outside of the pantry and

kitchen doors, and other places indicated by the shiny slime-tracks

as points of entrance, will do these pests up every time; the salt

adheres to their sticky bodies, dissolves and is absorbed, and the in-

truders are literally corned to death. For all places about the

dwelling-house, salt is the safest and most effective article. Air-

slaked lime that has not lost all of its heat is also good. This should

be used freely in cellars and basements, and other places of conceal-

ment where the slugs occur. Another remedy, excellent, but too

poisonous to be used unless safely placed out of the way of children

or pet animals, is made by taking the refuse of the soup-kettle, add-

ing water so as to make when stewed a gruel of the consistency of

molasses ; mix with it, after straining out the coarser portion, some

Paris green ; daub pieces of board or old shingles with some of the

mixture, and place near such spots as‘are indicated by the tracks.

This prescription is a settler.

36 THE NAUTILUS.

Having experimented successfully with these ‘“‘ remedies,” I can

assure satisfactory results. Of course trapping under pieces of

board placed here and there, turning the same occasionally and col-

lecting by hand, may be practised with more or less success.

In England, in wet, cool seasons, slugs are particularly destruc-

tive to fields of young wheat; there they work at night. Lime is

used to a great extent, and trapping under cabbage and other large

leaves is often resorted to. Soot is sometimes used in the wheat

fields in the same way as lime.

Another foreign slug Limax (Amalia) hewstont (=A. gagates ?)

had become a nuisance in the grass plots of San Francisco twenty

years ago, and has presumably extended its territory over a larger

area by this time. Our large native slugs, Limax (Ariolimaz),

columbianus Gld., and its near relative californicus Cp., inhabitants

of Central California, the first-named found also as far north as

British Columbia, appear to be free of the sins which have made the

foreign forms obnoxious. These two species are sometimes met

with of the length of six inches. Their dirty yellowish green color,

often blotched or spotted, is rather repulsive. It is not unlikely that

slugs may become a serious pest to the farmers in some parts of Cal-

ifornia at some future time, an unwelcome incident pertaining to the

development of irrigation.

The sense of smell seems to be highly developed in L. maximus,

and probably in all of the slugs, and again, the sense or instinct of

direction. L. maximus is the only species that I have had an oppor-

tunity to observe in this connection. The slugs are “ not popular

with the masses ;”’ and very good people call them ‘ nasty things.”

LIST OF ALABAMA SHELLS COLLECTED IN OCTOBER AND

NOVEMBER, 1903.

A. A. HINKLEY.

For several years I have been interested in the variations and

geocraphical distribution of the family Pleuroceride of our fresh

water shells. Under the same environments a species will often

show considerable variation, while specimens from widely different

stations will show very marked differences which are often confusing

in the determination of species. This has been one cause of the large

synonymy of this group.

Last fall I had the pleasure of a short visit to several of the

streams from Decatur to Montgomery, Alabama. At Decatur, a

stop between trains did not allow much time for collecting.

At Blount Springs, Randolph creek was followed over most of its

rock-bed between the mountains, from the railroad to the bottom

lands of the Mulberry river. ‘The river was followed up stream for

several miles. Most of the distance the water was shallow, flowing °

over a seamed rock-bed.

The Black Warrior was followed from the wagon bridge near

Warrior to the L. and N. R. R. bridge. The only shoal places were |

at the two bridges.

The Bucksehatchee creek near Calera was a water course with

pools here and there. ,

A walk-of three miles from Calera to Wilson’s creek gave an

uals were not numerous until the town was reached, where in some

places the bed of the stream was literally covered with Goniobasis.

A large spring at the edge of the town furnished several species.

The Coosa river at Farmer, Shelby Co., offered no good collect-

ing places, but farther up the stream at Ft. William’s Shoals the

stream was explored for considerable distance with very satisfactory

results. In the clear, shallow water everything was plainly visible,

the colors of the shells often showing with remarkable distinct-

ness. Shoal creek, below Farmer, contained but few individuals.

At Wilsonville only one small shoal was searched.

At Wetumpka there are more accessible places for collecting than

at any of the other Coosa river localities visited.

The Tallapoosa river above Tallassee, is a much broken stream

caused by a rough rock-bed, with a considerable fall.

The Pleuroceridx were looked for closely, and especially the Coosa

river forms;°but many described species and others listed from that

stream were not found. Some of them were undoubtedly overlooked

or are to be found in other situations than those explored, but I

think the earlier collectors in some way mixed their collections ; and

species are credited to the Coosa river which were not found there,

while some of the Coosa river forms were credited to other streams.

This subject is open for further investigation.

For aid in determination of the species, thanks are due Prof. Pils-

bry for kindly comparing a large part of the Pleurocerid@ and part

of the Unionidez with specimens in the Academy of Natural Sciences,

and for describing some new forms of Limneide. To Mr. Bryant

Walker for his excellent work with new forms of Somatogyrus, etc.

and identifying part of the Heliccde and Unionidae. And to Dr.

Sterki for identifying the Corbiculide.

Very little attention was given the land shells and the fresh-water

- species which inhabit muddy situations. The Unionide were taken

as they were noticed while looking for the Plewrocerida, so that this

list is not as full as it might otherwise have been.

In the genus Schizostoma or Gyrotoma, the fissure appears to be

the most constant character, while the striz, carinez, nodules, bands,

ground-color and outline, all vary more or less.

S. castaneum Lea. Coosa River, Wetumpka and vicinity. Mature

specimens were rare. Fissure deep and narrow ; three- or four-_

banded, when four-banded the two middle ones are approximate.

The carina is obscure except at the tip of the young; the spire of

mature specimens is eroded giving them a cylindrical shape.

S. constrictum Lea. ‘The most plentiful species of this genus at

Fort William Shoals, generally three-banded, smooth or inclined to

be nodulous below the hem; differs from incisum by the fissure being

more direct and deeper, ground color lighter, the bands are more dis-

tinct. Jncisum is never nodulous. S. amplum and salebrosum are

DPMIANQAQA

synonyms.

S. ellipticum Anth. (syn. bulbosum Anth.). Wetumpka and Wil-

sonville. Several hundred specimens show considerable variation,

many are smooth, others more or less striate, some quite distinctly

nodulous, three-banded, the bands generally broad, giving the shell

a dark appearance. SS. cylindraceum may be a form of this species.

- S. glans Lea. Fort William Shoals, close to ellipticum if not a

synonym.

THE NAUTILUS. 41

S. excisum Lea (syn. pumilum Lea). Wetumpka and vicinity. —

Varies from cylindrical to globosely ovate, banded or without bands,

those without bands are mature and nearly all of them show a dis-

position to have bands on the first whorl. The cord-like elevation

behind the fissure is well developed on some while others show very

little or nothing of it. The striz are generally distinct. The fissure

is direct, medium in length and width.

S. glandula Lea. Described from one specimen. The only

noticeable difference from ineciswm, of which it is a color variety,

is the light color and the bands more narrow and distinct. The

color and bands resemble constrictum, but the fissure places it with

incisum.

S. incisum Lea. The most plentiful species of this genus at

Wetumpka. The fissure is very short, wide and oblique, in some

cases only a sinuous outer lip. The three broad bands are clouded,

giving the shell a dark color.

S. lewisii Lea. Coosa River, near Wilsonville, Ala. Two

specimens referred to this species may be only elongated forms of G.

umpressa with a very sinuous outer lip.

S. ovotdeum Shutt. Wetumpka. .

S. pyramidatum Shutt. (syn. pagoda Lea, wetumpkaensis Lea,

babylonicum Lea).

Shell smooth, striate, or carinate, four-banded or without bands.

The carina, always prominent on the young, disappears with the

erosion of the spire. The fissure is short and constant in character.

Pagoda was described from three specimens. In his description of

wetumpkaensis Mr. Lea says it is umblicate. I find this is not the

case with all the specimens and especially the young, nor is the

supposed umbilicus confined to wetumpkaensis. ,It is not a true

umbilicus but caused by erosion. SS. babylonicum was described from

one specimen and I think it only a mature form of that described as

wetumpkaensis. Showalterii and demissum may also be forms of

this species.

Anculosa ampla Anth. There are not many specimens which I

refer to this species. The epidermis and character of the bands,

outline of body-whorl, and shape of aperture, differ from picta and

all its varieties. The columella of the specimens from Fort William

Shoals is always purple’; it is white in a few specimens from Wet-

umpka and vicinity.

42 THE NAUTILUS.

A small variety found on the exposed surface of stones in the swift

current, is remarkably depressed with a very large aperture. The

columella is broad and thickened its entire length; it is sometimes

white instead of tinted and purple; the spire is very much depressed,

hardly extending beyond the body-whorl; when placed aperture

down, the apex is low down on the right side. One of the largest

specimens measured over the columella, is .380 of an inch, the largest

measurement is .40 of an inch. When placed aperture down, the

height is .21; extreme length of aperture .30 of an inch, width from

center of columella to outer lip .19 of an inch.

It seems to me that the forms described as A. elegans and A. for-

mosa Lea, more properly belong in the synonym of A, picta instead

of ampla. Young specimens referable to these varieties appear to be

only color varieties of young picta. |

A. melanoides Conrad. This unpretentious species was found on

pebbles in strong current in Black Warrior River at a bridge near

Warrior. The spire is more elevated than usual with the species of this

genus, the perfect ones have four whorls, the spire of most specimens

is eroded, only two whorls left.. A few are banded, but most have no

indication of bands. Mature specimens with eroded spire measure

.40 to .45 length and .28 to .30 inch diameter. Columella a little

thickened at the base and the aperture angulated at the juncture of

the columella and outer lip.

A. picta Conrad. Common at Fort William Shoals, Wetumpka

and vicinity. A very variable species, smooth, sometimes corded or

plicate, or both. The bands extremely variable. The most common

form is eight to twelve narrow bands made up of dots and dashes.

These may be placed so as to form diagonal stripes as in A. zebra

and flammata, and in some instances these diagonal bands are so

strong as to blur the revolving lines of dashes. The bands are often

continuous and number from two to twelve, or the two characters of

bands may be alternate on the same specimen. Many are imper-

fectly banded and a few without bands, occasionally one in purple.

The columella is often purple or tinged with that color; the prevail-

ing color is white, the plica are often waves or folds. The shell may

be globose. In old specimens the body-whorl is often compressed

above the periphery, sometimes giving the shell a distorted appear-

ance,

A. plicata Con. Black Warrior River at Warrior, Ala., common.

THE NAUTILUS. 43

At this locality the species is not typical ; among several hundred

there are few with small or indistinct plication. Most specimens are

smooth with the exception of a raised line a little below the suture,

which is more or less crenulate. Many specimens are three-banded,

‘the upper one just below the raised line and narrower than the other

two. None were found in the Coosa River.

A. ligata Anth. Wetumpka. The young of this species was often

found on the under side of rocks in swift water.

A, rubiginosa Lea. Coosa River at Wetumpka also found at Wil-

sonville. More or less striate, in some striz are remarkably well de-

veloped, producing costate specimens with a crenulated outer lip, In

form they vary considerably. Some of the plicate specimens have a

little resemblance to A. plicata, but evidently are. nut that species.

Specimens with an elongated operculum were found in only one

situation, on the west side of an island above the Wetumpka bridge;

the length of the operculum seemed to have no reference to the size

of the shell. Occasionally one will have a clear, white columella.

They are generally attached to rocks and pebbles in the current, and

the colors show up bright and distinct through the clear water of the

stream.

A. taeniata Con. The specimens I refer to of this species may be

a smooth form of rubiginosa.

FAMILY VIVIPARID*.,

Viviparus contectoides Binney. n. var. Decatur. In a small

swamp deeply shaded by a heavy growth of trees, this species was

quite numerous. Mature specimens were rare, the larger part being

very young to half grown. |

Tulotoma mugnifica Con. Coosa River at Fort William Shoals

and Wilsonville. This species was nearly always found on the

under side of rocks where there was little or no current. They were

generally in colonies ; it was not uncommon to find 20 or 30 under a

single stone a foot square or more.

T. magnifica Con., variety bimonilifera Lea. Farmer and Wil-

sonville. This form was found only in a fossil state. In some places

they were numerous in cultivated fields and some distance above

high-water mark. The size averaged larger than the living magnifica

and the lower row of nodules is more strongly developed.

T. angulata Lea. Coosa River, Wetumpka; this form differs

44 : THE NAUTILUS.

from magnifica by being smooth or nearly sc, some being nearly as

smooth as viviparus. They are found under rocks in the swift

current of the stream. Both forms, magnifica and angulata, vary

greatly in color from a light horn to a dark purple.

very few; nearly always found on the underside of the rocks associ-

ated with S. coosaensis and S. hinkleyi, very seldom more than one on

the same rock. The light color, eroded spire and deep suture made

them easily noticed among other species.

S. coosaensis Walker. Wetumpka, Fort William Shoals; common.

On rocks in swift water; sometimes 25 to 30 were seen together.

S. crassus Walker. Wetumpka and Fort William Shoals; not

plentiful. ,

S. hinkleyi Walker. At all localities in the Coosa River, One

specimen supposed to be from the Tallapoosa River above Tallassee,

was probably mixed with S. palsbryanus by accident.

S. nanus Walker. Very plentiful at Fort William Shoals. They

literally covered the rock-bed of the stream in favorable situations,

showing up very plainly through the clear water, but owing to the

swift current it was difficult and tedious collecting them.

THE LAND-SHELLS OF IRONBOUND ISLAND, MAINE.

BY DWIGHT BLANEY.

The following land-shells have been collected on Ironbound

Island, Frenchman’s Bay. This is one of the many rocky islands

on the coast of Maine—with high cliffs toward the sea, and sloping

to the water on the bay side. 7

Heavily covered with spruce mixed with a few birches, and with

comparatively little cleared land, it does not seem a very likely place

for collecting land-shells. Under the guidance of our friend Prof.

Edward S. Morse, we have ransacked all favorable situations, and

feel well rewarded with the following nineteen species.

The numerals refer to Pilsbry and Johnson’s Land-shells of

America.

No. 141. Polygyra monodon (Rack.), common.

No. 200. Pupa muscorum (L.), common.

46 THE NAUTILUS.

No. 224. Vertigo ventricosa (Morse), common.

No. 224a. Vertigo ventricosa var. elatior, (Sterki), rare.

This species is noted in the catalogue as from Ohio, Michigan and

Minnesota.

226. Vertigo bollesiana (Morse), rare.

260. Vitrea hammonis (Strém), rare.

264. V. binneyana (Morse), common.

268. V. ferrea (Morse), common.

278. Euconulus fulvus (Miuill.), common.

283. Zonitoides arboreus (Say), abundant.

293. Z. exiguus (Stimp.), common.

494, Z. milium (Morse), rare.

338. Pyramidula alternata (Say), abundant.

344, P. striatella (Anth.), abundant.

346. Helicodiscus lineatus (Say), common.

248. Punctum pygmzum (Drap.), common.

353. Sphyradium edentulum (Drap.), rare.

362a. Succinea obliqua totteniana (Lea), common.

367. S. avara (Say), not common.

The Pupa muscorum L. was found in a most interesting situation.

On the seaward side of the island, on a rough, stony beach, rises a

pinnacle of rock many tons in weight. This is nearly fifty feet high

and is separated from the main cliff by about forty feet. I climbed

one day to a flat place near the top, three feet square, covered with

Juniper bushes, to gather some wild bluebells, Campanula rotundt-

folia L., and while clinging in this narrow space, picked over the

valves of clams and mussel shells brought by Crows. Needless to

say, I was inspired to find hidden in the lower shells, deep in the

bushes, quite a colony of Muscorum. This is the only place on the

island where this species is found, and a careful search on the adja-

cent cliffs revealed no more of them. How they could have got

there is of course an interesting problem. Two fresh-water species

are found on the island. Pistdiwm abditum (Hald.) and Lymnezxa

caperata Say, and the following land-shells have been found on

neighboring islands. |

13. Helix hortensis Mull, Little Duck Island, common.

NOTES ON SOME CAPE COD MOLLUSCA.

BY C. W. JOHNSON,

During a recent trip on Cape Cod, Mass., I was mostly interested

in studying the insect fauna, but incidentally collected a number of

shells. One ofternoon, at low tide I wandered over the sand-flats of

Provincetown harbor; on my way out I met a little Portuguese boy |

(Portugese, by the way, constitute about one-third of the population)

with a bucket full of periwinkles (Litorinalitorea). I asked him what

he was going todo with them. ‘ Kat ’em,” was hisreply. To my

inquiry whether they were good, he said, ‘“‘ Yep.” The piling and

rocks (the remains of an old pier) were literally covered with them ;

over almost everything was a coating of small barnacles (alanus

balanotdes), and it was interesting to see the load carried by some of

the periwinkles, often greater in size than the shell itself.

On every hand were trails of the sea-snails, but I was suprised to

find that Polinices (Neverita) duplicata far outnumbered P. (Lunatia)

heros ; the former were much smaller than those I have collected on

_the New Jersey coast, and their nidimental bands, popularly known

as ‘‘sand collars,”’ were also correspondingly smaller. The nidus of

P. duplicata is readily distinguished from those of P. heros by the

lower or expanded margin being undulated or wavy. One specimen

of Columbella avara was found. Of the Pelecypods, Pandora gould-

ana was abundant, and two specimens of the old Cytherea convexa

Say (which we must now call Callocardia morrhuana Linsley), were

collected. In places the coarse sand had a dark purple line. Close

inspection showed it to be made up of the little Gemma gemma.

At Eastham are located a number of large fresh-water ponds,

with no apparent inlet or outlet, in which the water is very clear,

and quite cool. In the one nearest the station, called Depot Pond,

I found three species of the Unionide. Allof them were undersized,

and very much eroded, features characteristic of still water, even

though apparently more pure than many streams. The specimens of

Unio complanatus were about two inches in length. It was by far the

most common species, although dwarfed Lampsilis radiatus, about

two and a quarter inches in length, with a thick, dark, sparsely rayed

epidermis, was also abundant. The other species was a very fragile

example of Anodonta cataracta Say (A. fluviatilis Dillw.), about two

48 - THE NAUTILUS.

inches in length. Attached to shells and stones were a few Amani-

cola limosa, Under an old board I found a colony of Pyramidula

striatella associated with Zonitotdes arboreus. In the salt marshes °

east of the station Melampus lineatus was in great numbers, together

with a few Litorina rudis var. tenebrosa.

My first stroll along the beach at Chatham was at high tide. Com-

ing upon some lobster pots I found quantities of animal life strewn

about. Among them were beautiful specimens of Polinices heros, but

the animals wers dead, and were left behind because they took up en-

tirely too much room for their size ; they were like some specimens

a friend once described as “ dead, but not gone, and unwilling to be

forgotten.”” The next day, at low water, in the littie bights between

the several bars which extend out from the beach south of the inlet,

were to be seen hundreds of specimens of P. heros of all ages, from

the size of a pea to one nearly four inches in length, while the nidi-

mental bands were unusually large, and owing to the coarse sand ex-

ceedingly handsome.

Among the other interesting shells were the Arcas of the New

England coast. Arca transversa and A. pexata Say, or as we must

now call it A. campechensis Gmel. Is not this northern form worthy

of a varietal name? As Say’s description covers both, can we not

restrict his name to this form as described and figured by Gould ?

Scattered along the outer beach we found upwards of twenty single

valves of Arca ponderosa Say, several with portions of the ligament and

epidermis in place. To findso many of this species at the extreme north-

ern limit of its distribution was a surprise; it seems even to be more

plentiful here than on the New Jersey coast. Mesodesma arcuatum

was very common; a few valves of Cochlodesma leanum, Astarte

castanea and two valves of Divaricella quadrisulcata were also found.

In a heap of scallop shells Peeten gibbus var. borealis Say (Pecten

trradians of authors), I obtained some very interesting examples of

Crepidula fornicata, many of the specimens in adapting their shells

to the surface of the scallop becoming strongly ribbed.

A rainy day had its advantages; it not only gave me a chance to

attend to all the material I ‘had collected, but it brought out the Helix

hortensis in great numbers along the steep bank near the light-houses;

they were all of the light-colored, bandless variety. J am not aware

that this species has been recorded from this plies which’ adds

another locality to the mainland records. | ‘i

SOUTHWESTERN SHELLS.

BY JAS. H. FERRISS.

Joliet has a botanical park where nature herself made a good start

in a collection. Fast as the money and friends can be had the col-

lection is being improved. I am superintendent of the ferns upon a

salary of 25 cents per year, which is to be paid whenever the com-

missioners have their salaries increased to that point. An effort to

complete a collection of the U. S. ferns and cacti has led me into the

Southwest after rare examples.

I was surprised on the first day out to find shells among the fern

roots upon the hot side of the Franklin Mountain at El Paso, as

surprised as when the ferns were found in the first place. This

mountain of clay and rock, thoroughly baked, is as uninviting to the

collector as a well-used brick kiln. There were two shells there,

Holospira roemeri Pfr. and Bulimulus dealbatus pasonis Pils. This

will be a species some day. Of less than twenty species found upon

this first trip, six were new species or varieties.

Not until the last half of the fern trip made the present year were

the snails given serious consideration. A collector will find few

specimens in a land where to him the conditions are new, unless he

gives his whole soul to the work.

Frank Woodruff, ornithologist and photographer of the Chicago

Academy was with mea couple of weeks. At Deming, N. M., we

formed an alliance with the city marshal who escorted us to the

Florida Mts., ten miles away. At Bowie, Ariz., an expedition was

50 THE NAUTILUS.

outfitted for the Chiricahua Mts. We wentas far as old Fort Bowie.

It was rather cold. Some mornings we crawled out from under

snow-banks. Water was scarce, and our guides inexperienced. - We

were after birds, ferns, snap-shots and Indian relics, and at the end

of two weeks had found only four snails—Sonorella hachitana Dall,

Ashmunella walkeri Ferriss, A. levettei Bld., and a Physa.

Former information told me the Chiricahuas were unexplored, and

were occasionally exploited by the Apaches. By cautious approaches

we made our way to the fort, now occupied by a single miner only.

Here we learned there had been no raids for five years, and that the

mountains were safe as the streets of Philadelphia. .

At the fort Mr. Woodruff turned back to El Paso and Albuquer-

que. With a miner, ponies and a burro I pushed into the higher

peaks. These run up about 8,000 feet. We pitched our tent in

Cave Creek Canyon, and altogether it was a delightful situation,—

caves, strange birds and plants, mountain streams, heavy forests,

every day perfect, good folks, and new shells around every point.

The miner herded the ponies, prepared warm suppers, and my regu-

lar daily grist was two shells I had never seen, and a new fern to

the territory. The last day we packed up and visited a,cave a

quarter mile from our camp. Upon our return we found four snails

we had never seen. ‘I'wo were new species.

The next day we rode up a wagon road to.a saw, mill in a heavy

pine forest at the top of the mountain. I walked a little and found

one new species, two varieties and two I had not seen in the terri-

tory. This was a government forest reserve, and here we found

Chas. T. McGlone, of Ashland, Ky., in charge, with a lion hunter

for a partner, and the partner had a fiddle. The canyons are deep,

heavily wooded and. well watered; and truly at parting my heart

was heavy. I know many species of snails were left behind.

The mountains seem rather difficult to reach from the railroads.

They are far away, cattle ranches are about ten miles apart, and

there are no stages or hotels, but the approach is easy enough, like

snail hunting itself, when you catch on. From the Huachuca

station on the Sonora branch of the Southern Pacific 1 walked fifteen

miles across the plain to a canyon formerly visited, and in the next

month wore out another pair of hob nails. I left home with rheuma-

tism, dyspepsia and several more or less important defects, but was:

so busy no inventory had been taken since crawling out of the snow

in the Chiricahuas. The first Sunday morning in the Huachucas I

rested up a-little, and’found ‘there was nothing out of repair ene a

few fingers. © l‘am not afraid of an automobile now.

‘ Truly, snails were as thick together on the under surface of rocks

as mussels are found on the seashore: - At the very peak of one of

the highest mountains, composed of slabs of limestone, there was not

enough stone to cover the Oreohelix. They were hibernating on top

and glued together in masses. + Upon one side of the peak a dark

banded variety was found, upon ‘the other, not-two hundred feet

away, a white variety. This shell seems to be a home-body. A

canyon though tlrree miles in length from top to bottom, was usu-

ally peopled by one variety. Over a divide but a few steps was

another variety, though every colony in the canyon was liable to

have some‘distinctive mark in size, color or form. And this was

true of the Ashmunellas. No two colonies seemed: exactly alike,

and they did‘ not visit back and for a nor travel far from the best

pk of their own rock pile.

‘On the south side of the Huachucas I found a colony of typical

-Ashmunella chiricahuana about one-half albinoes, a mile west a

colony of typicat Ashmunella levetter, nearly all albinoes. Half a

mile lower down the /evetted were chestnut-colored and polished. In

between these three colonies were light horn-colored shells running

from typical Jevettei with four large teeth to typical chiricahuana

with no teeth at all, and all forms between, one tooth, two teeth,

three teeth, rudimentary forms of these, and mere suspicions of teeth

or thickening of the lip. Did these two species come together here,

or was this the exact spot upon which the original Ashmunella

Adam and Eve located? It is up to Dr. Pilsbry. I have described

two species there can be no mistake in. With no courage left, the

whole responsibility is now duniped upon his shoulders. The last

heard from Messrs. Clapp and Walker, they were running too.

Some of the Oreohelix are black, white, brown, red, banded, lined,

speckled, mottled and variegated, of only ten mm. diameter. Other

colonies of similar colors were of twenty-five mm. diameter,. Some

were carinated, some as round-barreled dnd as umbilicated as a

Circinaria, some depressed, and some were old-time bee-hives. The

levettei colonies, outside of the albino camp, varied from dark chest-

nut to dull white, and from ten mm. diameter to twenty millimeters.

is the home of tne snails. A good snail hoe is necessary, and one

should wear gloves, for the chemicals, or climate, crack the collector’s

hands. A little shade helps, and the colonies will be found where the

ventilation is good, the soil sweet and with a normal condition as to

moisture, not wet or springy, but a natural soil condition. The

most favorable location is selected, and the collector must not be dis-

couraged at the absence of dead or living shells until after the

thorough overhauling of a slide. Ashmunella chiricahuana was

found, one by one, but after digging away at a rocky slide for an

hour without results I found one pocket large as my hat with 85 ex-

amples, and soon after took 125 from a like pocket, and left the rest.

Oreohelix and Ashmunellas were nearest the surface. Though

hibernating, Oreohelix would be often found under the top stone.

The Ashmunellas were next to the soil, and often buried in the

loose leaf mould. Sonorellas were deep delvers, and lived down

where the stones were wedged close together or buried in the soil.

Seldom were more than one, two or three specimens found in one

colony, not counting the little fellows, but such as they were I have

never seen Shells thicker in the southern mountains. I found a

number of small shells in the drift on the plains which I did not find

alive. Holospiras were usually found under dead vegetation upon

dry hill-sides. Vitrinas were in damp ravines in the decaying vege-

tation. IJnfundibularia tuba Pils., was found in the drift of the San

Pedro at Benson. It was not found in the Huachucas, or the drift

of the streams from those mountains, and therefore I suspect it came

from the mountains near Tombstone. There are a number of species

credited to the Huachucas and Chiricabuas I did not find.

Fort Huachuca is a division headquarters of the army, and is

occupied by three or four troops of cavalry. Many collectors visit

the post and the mountains. Botanists and entomologists predomin-

ate. These mountains are probably no better than many others in

the territory, but are good, and the collectors in the army lead the

way. In the Carr Canyon I found C. R. Biedermann in a cabin of

his own. He expects to remain there two or three years studying

Arizona insect life for the Philadelphia Academy. From what he

has told me of strange snails in strange places, and from what I have

seen and run over without seeing, I am satisfied there is fully two

years’ hard work ahead for the collector who will do Arizona justice.

I will do what I can, but all assistance will be cheerfully welcomed.

THE NAUTILUS. 538

It is an open field, and the climate is glorious. Take a guide, for

water is scarce. The verification of these wonders is now left to Dr.

Pilsbry. He has the evidence.

Ashmunella walkeri Ferriss, n. sp.

The shell is much depressed, lens-shaped, acutely carinate peri-

pherally, rather thin and pale corneous-brown. The umbilicus,

narrow within, enlarges rapidly at the last whorl. Surface nearly

smooth, very lightly marked with growth-lines. Whorls 44, slightly

convex, the last very shortly descending in front. Base more con-

vex than the upper surface. The aperture is small and very oblique,

the lip well reflexed, white, with an obtuse, squarish tooth in the

outer margin and two compressed teeth in the basal margin, the

inner one smaller; these three being nearly equally spaced.

There is a rather short, straight, obliquely set parietal tooth. Alt.

41, diam. 134 mm.

Florida Mountains, Luna Co., New Mexico. Found ina tumble

of rock near the top of the mountain, probably an elevation of 6,500

feet. Only a few were found, and none found at any other place.

Cotypes in collections of J. H. F.and A. N.S. P. This very dis-

tinct species differs from all other known forms of the devettes group

in the small number of whorls. It is also flatter and more acutely

Oreohelix clappi Ferriss, ‘n. sp.

The shell is moderately depressed, the alt. about two-thirds the

diam., and about equally convex above and below the obtuse peri-

pheral angle. ‘The umbilicus is about one-sixth the diam. and con-

tracts rapidly within. It is brownish-white under a thin greenish-

yellow cuticle with some darker oblique streaks and two indistinct

brownish bands. In old individuals the cuticle remains only in

small shreds. Sculpture of irregular growth-wrinkles and very fine,

faint spiral striz, nearly obsolete on the upper surface. Whorls 43, .

convex, the last double the width of the preceding, the first 14 rad-

ially obliquely costulate. Base very convex. The aperture is short-

oval, nearly circular, and very oblique. The ends of the lips con-

verge, and in old shells are continuous, being connected by a short

raised parietal ledge.

Alt. 9.6, diam. 15 to 16 mm.

Alt. 9, diam. 14 mm.

Cave Creek Cafion, Chiricahua Mts. Cotypes in collections of

J. H. F. and A. N.S. P. Found alive, buried deeply in rotten shale

about the base of cliffs near the stream.

This species differs from all the forms of O. strigosa by its radially

costulate apical whorls and greenish cuticle.

THE CAMBRIDGE NATURAL HISTORY: ERRATA CORRECTED.

ROBERT E, C. STEARNS.

On page 38, Vol. III., “ Molluscs, ete:,” of the Cambridge Nat-

ural History (1895), occurs the following :

‘Mr. R. E. C. Stearns records * a case of Buliminus pallidior and

H. veatchii from Cerros I., living without food from 1859 to March,

1865.” |

The figure 3’? refers to the Am. Nat., XI. (1877); p. 100;

Proce. Calif. Ac., iii, p. 8329, in the foot-note, as the sources of the

foregoing statement which contains about as many errors as it is pos-

sible to get in less than three lines. I am well acquainted with the

person referred to, and have been for many years, also with his

articles in the volumes named in the foot-note, and can safely assert

the word Buliminus does not occur in either of his:papers. He does

not say that the bulimoid form lived from 1859 to March, 1865, but

that examples of Bulimus pallidior lived from March, 1873, the day

they were collected, until June 22, 1875, two years, two months and

sixteen days, and that the specimens were collected at San José del

Cabo, Lower California; further, that one individual of the nine

was still living October 18, 1875. This species has not as yet been

reported from Cerros Island, where H. veatchii -was collected and

lived, as stated.

On page 278 of the Cambridge volume it says that the genus

Buliminus is peculiar to the Old World. I am not aware of its hay-

ing any representative in the Americas. We now write Bulimulus

for Bulimus, as I had it written in 1873.

equally fine decussating lines; below with arcuate, rather irregular

and wide-spuced delicate riblets and fine growth-striz, and rather

weak spiral lines. Whorls 6, very slowly increasing, convex, the last

slightly deflexed in front, the periphery near the summit, the base

very convex. * Aperture small, lunate, the peristome narrowly re-

flexed and a little thickened, connected across the parietal margin

by an elevated white, callous lamella. At its last third the last

whorl is obstructed within by a vertical parietal barrier, behind the

‘ends of which stand two tubercles, the upper one triangular, the

lower one oblong, each giving out a low callous towards the other ;

and by six palatal plice: the first minute, subsutural ; the second

larger, slightly oblique and curved ; the next three connected, larger

and more oblique, and the sixth plica smaller and standing on

the umbilical wall. Alt. 3, diam. 5.7 mm.; width of umbilicus 2

mm. Miyakojima, Riukiu. Types no. 87637 A. N. S. P., from no.

1295 of Mr. Hirase’s collection.

This is thé first Plectopylis found in the Japanese Empire, and is

one of the most interesting of Mr. Hirase’s many discoveries. The

admirable studies 6f Mr. Gude enable us to fix its position as nearest

the Chinese P. cutiscu/pta Mlldff. (see Gude, Science Gossip, iii,

180, 181, Dec. 1896, and Mlldff., Jahrb. D. M. Ges., ix, 1882, p.

Sonorella lohrii lioderma, n. subsp.

The shell is similar to Johri7, but ‘the last whorl is a little more

convex and evenly rounded, and the last two whorls are glossy, with

no granulation, being marked with faint growth-strize only. The

spire is sometimes a little more elevated than the type of S. lohri’.

GENERAL NOTES.

West AMERICAN SHELLS.—Professor Keep’s new book on the

shells of the Pacific coast is now in press, and will be published in a

short time. There will be over 300 illustrations: The marine

60 THE NAUTILUS.

shells include those of British Columbia and Alaska, and land and

fresh-water shells from west of the Rocky Mountains.

Crams AFFECTED BY SEWERAGE.—The local quahog, or little-

neck clam, and scallop industry is menaced by action of the State

Board of Health declaring the shellfish taken in New Bedford

harbor and Clark’s cove to be infected, and calling upon the commis,

sioners on inland fisheries and game to prevent further taking. The

number of men engaged in quahog-fishing here is about 300, and the

income involved ranges between $50,000 and $75,000.

The sewers of New Bedford and Fairhaven all enter into the river

and cove. The eagerness of the fishermen, many of them French-

Canadians, has carried them nearer and nearer to the sewers, until

they are frequently seen at work at the sewers’ mouths.

The board has been making bacterial tests since last spring, and

reports that the shellfish are polluted by the sewer.

The demand of the State Board will also affect the fall and winter

scallop fishing, another important industry.— Boston Evening Record.

ZOOLOGICAL RrcorRD FOR 1903.—The Zodlogical Society of

London is now issuing ‘ special records.”” Each volume is divided

into twenty parts. The part (VII.) on Mollusca by Mr. E. R.

Sykes, assisted by Mr. E. A. Smith, has been received. It contains

85 pages, the matter being arranged admirably for ready reference.

It is furnished by the Society for 4 shillings.

A New Locatrity in SoutH CaRoLina FOR RECENT AND

Fosstt Mo.iusks.—I write to call the attention of collectors to a

new locality in a new though old country. This is a long beach on the.

ocean front, without breaks for thirty miles, as Iam informed. An

ideal place for automobile explorations. I was only there for a half

day, and saw only a part of the shells, but they are there by the

millions.

There are many Cretaceous, Eocene, Pliocene and Pleistocene shells-

as well as immense numbers of recent specimens. The locality is

“¢ Myrtle Beach.’’ There is a ten-mile railroad from Conway over

there and a good hotel. Conway is the county town of Horry (pro-

nounced ‘* Oree’’) county, South Carolina, and has heretofore been

out of the world, but now has railroad connections with the Coast

Line Railroad, and is an ideal place for conchologists and botanists.

A NEW OYSTER FROM THE EOCENE OF ALABAMA.

BY T. H. ALDRICH.

eat td Pen

OsTrEA ARROSIS n. sp. Pl. III, figs. 1-4.

Shell oval, lower valve thick and heavy, upper valve thin. Sur-

face of lower valve strongly ribbed, ribs very numerous, close-set and

cross marked by growth lines, inner edge of lower valve is scalloped.

Both valves have a large, muscular scar, not central. The beak is

strong, making a stout hinge in the lower valve, much smaller in the

upper. ‘The upper valve is smaller, fitting into the other ventrally

above the crenulations; its surface is generally covered with fine,

raised lines of growth; interior with crenulations near the beak, be-

coming obsolete on the ventral margin. Size of old specimens 125

to 140 mm. from beak to ventral margin, about one-fifth less at right

angles across the shell.

Locality. F leming’s Mill, on Pea River, in Southeast Alabama,

from the Nanafalia horizon.

Remarks.—Figures 1 and 2 are the exterior and interior of a large,

lower valve; fig. 4, upper valve of young shell; fig. 3, young shell

with both valves in place. In old shells the ribbing becomes obso-

lete on the beak, and in some examples the beak is bent strongly to

one side. This oyster seems to be the precursor of O. sellaeformis

Con. Some young examples occur in the Alabama River lignitic,

but the full-grown shell has not before been found that I am

aware of,

NEW AMERICAN LYMNAEAS. II.

BY FRANK COLLINS BAKER.

Lymnza decollata oronoensis var. nov.

Shell very globose, inflated, solid; whorls 3-34, very convex, the

last almost globular; spire broadly conic, depressed, sutures a little

impressed ; aperture roundly ovate, the upper part shouldered two-

thirds the length the entire shell; columella with a distinct plait ;

umbilicus very narrowly open; color a rich greenish horn, inclining

to black in some specimens. ‘The spire is frequently decollated.

Length 17.00; width 11.50; aperture length 11.00; width 7.00

Length 16.00; width 10.00; aperture length 10.00; width 6.00

Length 17.00 ; width 12.00; aperture length 12.00; width 8.00

mill. | : |

Length 12.00; width 9.00; aperture length 8.75; width 6,50

mill. (half grown). )

Distribution: Orono, Maine. (Collection of Mr. Bryant Walker.)

This variety may be distinguished from decollata by its larger

size, more globose form of whorls and the whole shell, and the

rounded aperture shouldered at-the upper part. The young or half-.

grown shell somewhat resembles young individuals of mighelsi and

catascopium.

Haldeman’s figure 3 on plate 14 oF his monograph seems to repre-

sent a form of this variety. It appears to be quite a characteristic

variety. |

Judging from specimens received by Mr. Bryant Walker from

Mighels and examined by the writer, decollata has been figured

accurately only by Haldeman in his monograph, plate 14, figs. 1, 2.

The species has-not been upd crstoad by most American collectors,

specimens of emarginata, catascopium and mighelsic having been re-

ceived as decollata. It is, however, a very characteristic species,

not closely connected with any other form. ‘The variety oronoensis

resembles some young forms of mighelsi as well as some varieties of

catascopium. This resemblance, however, is merely superficial.

The typical decollata received from Mighels measure as follows :

"Length 12.00; width 8.00; aperture length 9.00 ; width 5.50 mill.

Length 9.75 ; width 7.00 ; aperture length 7.00 ; width 4.50 mill.

Lymnea randolphi nov. sp.

Shell large, generally inflated, ovate ; whorls five to six, rounded,

inflated, distinctly shouldered ; spire short, pyramidal; the first 3-4

whorls are small and regularly wound, but the last whorl abruptly

enlarges to more than four times the diameter of the preceding whorls,

causing the spire whorls to appear as though set upon a pedestal ;

‘sutures deeply impressed ; sculpture consisting of close-set, regular

lines of growth crossed by fine, impressed, spiral lines ; the surface is

malleated in many specimens and in some individuals there is a ten-

dency to form raised spiral ridges on the body-whorl; aperture very

large, ovate, almost patulous, distinctly shouldered at the upper

part; columella without distinct plait, but covered by a heavy, erect

callus which overhangs the umbilicus; umbilicus deep, widely open;

color probably horny as in the majority of Lymnezide, but chalky

white in the type specimens. Length 29.5, diam. 20, length of

aperture 19. mm.

Habitat: Marsh Lake, near Dyea Valley, Alaska, collected by

Mr. P. B. Randolph. )

-This is a very distinct species, not easily confounded with any

other. It has a superficial resemblance to Lymnza mighelsi Binney,

but that species is imperforate or at most only very narrowly per-

forated. The shape of the spire, the rounded aperture and the open

umbilicus will easily distinguish it.

Lymneza atkensis Dall, is a narrow species with a long spire, a

very narrowly open umbilicus and wholly lacks its peculiar shouldered

whorls. The sculpture is more marked in randolphi.

Cotypes are in the Academy of Natural Sciences of Philadelphia

and in tne Chicago Academy of Sciences.

A GLIMPSE AT THE SHELL FAUNA OF DELAWARE.

BY S. N. RHOADS.

Literature is strangely silent as to the fauna of the State of Dela-

ware. ‘To remedy this in some degree, as well as to satisfy a long-

64 THE NAUTILUS.

standing curiosity to compare the zodlogical features of the Bay

State with those of New Jersey, my old tramping ground, I paid her

five or six visits in different localities during the spring, summer and

fall of 1903. While these expeditions were mainly ornithological,

the Mollusca claimed more than passing attention, and a small col-

lection of specimens was made and presented to the Academy of

Natural Sciences of Philadelphia, where Prof. H. A. Pilsbry kindly

made the identifications and comparisons here recorded.

Disclaiming any but a tyro’s knowledge of conchology, it only re-

mains for me to preface these records by stating my conviction that

the evidence given by the vertebrates of Delaware indicate that her

southernmost border is more strictly Lower Austral than Upper

Austral. Certain species of birds and reptiles are found there which

do not occur in southern New Jersey or Pennsylvania. In the

Brandywine valley hills above Wilmington there is perhaps a shade

of approach to a preponderating number of species typical of the

Upper Austral and Lower Transition. In the upper Choptank

valley the Lower Austral finds its most northerly reaching arm on

the Atlantic seaboard, and the bird fauna there found in the thickly-

forested bottoms is a curious combination of three distinct sub-faune,

one northern, one western, and another southern. (R.)

In general character, the snail fanna is nearly identical with that

of eastern Maryland west of the Chesapeake, but there are a few

somewhat conspicuous differences, such as the occurrence of typical

Polygyra tridentata, in place of P. t. juxtidens, in Maryland, Pyra-

midula alternata fergusoni (Bld.) is another species of the coastal

plain, which has not yet been found in Maryland or eastern Penn-

sylvania.

The Unionide offer unexpected interest by the finding of a colony

of dwarf races of several species at Seaford, Sussex Co. (P.) Sea-

ford is at the head of navigation on the Nanticoke River, an affluent

of Chesapeake Bay, and lies near the centre of the level region reach-

ing, with but slight elevation above high-tide level, across the entire

peninsula. It isa sandy loam country with stretches of piney up-

lands and extensive areas of half-swamp lands. The left bank of the

river is fifteen to twenty feet high in some places. Some scattered

cypresses and white cedar occur on the left bank, but have nearly

been exterminated. The botany and vertebrate zodlogy of the region

are Lower Austral rather than Upper Austral in their prevailing

THE NAUTILUS. 6d

species, this being the dividing line between the two faunal regions,

(R.)

In this locality the Uniones are normal in shape, but very much

smaller than in other places in Delaware and the neighboring states.

Adult specimens of Unio complanatus measure 42 to 52 mm. long

(the normal size being 70 to 95 mm. in other Delaware streams).

U. fisherianus is 40 to 43 mm. long, against 95 to 108 mm. at

Choptank Mills.

Lampsilis cariosus, 40 to 44 mm. long.

Lampsilis ochraceus, 40 to 50 mm. long.

Lampsilis radiatus, 42 to 48 mm. long.

Lampsilis nasutus, 50 mm. long.

The whole Unio fauna is thus dwarfed, the shells being from about

half to two-thirds the ordinary size. (P.)

It has occurred to me that the dwarfing of the Unionide of the

Nanticoke may be due to the fact that no tributary of this sluggish

river runs through a soil furnishing ingredients favorable to shell

growth. ‘The relative sluggishness of this whole river system may

also have the degenerating effect of non-resistance. (R.)

mer Stone are included, such records being duly credited :

NOTES AND NEWS.

A Prcouuiar Hatioris.—Not long ago a freak in the Haliotis

line came under my observation, and thinking it of sufficient interest

to the readers of Tue Nauritus, I send the following description :

The shell is, in most particulars, a characteristic Haliot’s cracherodii,

measuring 4% inches in length, 1,5; inches in height,.and 33 inches

in width. It was obtained from a lot of shells brought from the

coast of Lower California, by Frank Holzner, a local dealer in shells

and curios, and unlike any other I have seen, has no holes whatever,

and no scars or indentations to’ indicate even a good intention in

that direction.—F. W. Kesey.

New Cave-Snairts.—Dr. R. Sturany has been investigating an

interesting collection of snails from caverns in Herzegovina (V6/.

D. M. Ges. for July-Sept., 04). Besides ‘species of Clausilia and

Pupa, he describes a very small subcylindric land-snail with a round

mouth and hairy cuticle as Pholeoteras euthrix. It is 2.5 to 3 mm.

‘long, and has minutely latticed sculpture, beginning even upon the

embryonic whorl. As only empty shells were found, and nothing

resembling them is known, the position of the new genus is left un-

certain. It is curious that with the exception of a Carychium dis-

covered by Dr. R. E. Call in Mammoth Cave, no cave-snails have

been found in America. Those having opportunities should search

in other caves of this country. .

PUBLICATIONS RECEIVED.

MoLLusca OF THE ‘* PorcUPINE”’ ExprpiTions.—By E. R.

Sykes (Proc. Malac. Soc., London, VI, 1904). The material col-

lected by these dredging expeditions in the northeast Atlantic, etc.,

was not wholly examined by Jeffreys, whose death interrupted the

work. Mr. Sykes is now supplementing his valuable reports, the

first paper dealing with the Tectibranchs. A number of new forms

are described, with valuable information upon others. An excellent

plate illustrates several little-known species. |

A CriticaL List oF THE SPHAROSPIRA SECTION OF THER-

sitEs.—By Hugh Fulton. (Journal of Malacology, XI, 1904.)

With the specimens from the Cox and Beddome collections, Mr.

Fulton has critically revised’ this group of handsome Queensland

Helices, correcting numerous errors in former works, and naming as

new T. consors, a form figured as 7. parsont Cox in the Manual of

Conchology. - It is only fair to say that most of the errors in former

works were due to wrongly named shells sent out by Cox and other

Australian conchologists. ‘The work seems to be well done and will

be of value to collectors having these fine Australian snails.—H. A. P.

An HisToricAL AND SysTEMATIC REVIEW OF THE FROG-

SUELLS AND Trirons—By W. H. Dall. (Smithsonian Misc,

Coll., Vol. 47, 1904.) Perhaps no prominent gastropod family has

suffered such vicissitudes of nomenclature as the Tritons. Dr. Dall,

without going into their morphology to any length, has fundamentally

examined the nomenclature and taxonomy of the group from the

earliest times, and gives in this paper the results of an investigation

of the early literature of the groups, which may well be called ex-

haustive. In the Ranellid@ he recognizes one genus, Bursa Bolten,

THE NAUTILUS. 69

equivalent to the old genus Ranella. The Tritons are arranged

thus :

Family Seprip&.

Genus Trachytriton Meek (Cretaceous only).

Genus Personella Conr. (Eocene, and perhaps including the recent

Triton quoyt Rve).

Genus Ranellina Conr. (Eocene).

Genus Gyrineum Link (Tritons with continuous lateral varices).

Genus Eugyrina Dall (Type Ranella gigantea Lam.).

Genus Argobuccinum Morch (Type Ranella vexillum Brod. In-

cludes also the West Coast species Priene oregonensis Redf., etc.).

Genus Distortrix Link (Distorsio of authors).

Genus Cymatium Bolten ( Triton femorale, etc.).

Genus Septa Perry (Large forms such as T. tritonis, etc.).

In recent years all of these groups containing recent species have

been generally recognized under one name or another. Cymatium

contains nearly all the forms ordinarily called “‘ Triton’ except those

segregated in Septa, a group which Dall considers sufficiently differ-

entiated for generic rank, although Kesteven and others have opposed

this view.

The classification proposed by Dall will, we believe, meet with

general approval. It seems worthy of acceptance pending the inves-

tigation of the soft anatomy of the snails in question, which is still

imperfectly known.

The chief innovations in generic nomenclature of the two families

are for the most part consequent upon the adoption of the Museum

Boltenianum as an acceptable source of nomenclature,—a_ position

still in debate. This work is so excessively rare that it is hardly to

be called published in the ordinary sense. Of the first edition—

which is the only one seriously affecting nomenclature—there is one

copy in America and we suppose not over half a dozen, if so many,

known in the world. Even in Germany, Herrmannsen, over fifty

years ago, could not get access to a copy, though he made concholog-

ical literature an exclusive study for years. The work has other

objectionable features, as the free use of polynomials, such as Cym-

bium cochlear neptunt, Cardium cor auritum, Murex mitra episcopalis,

Cassis mitella polonica, Neptunea corona mexicana, etc. Nobody who

swallows these ought to choke over Chemnitz. It is evident that

‘some general consensus of opinion is called for, before it will be ad-

70 THE NAUTILUS.

visable to throw aside the clear-cut images of Lamarck and his school

for their nebulous prototypes in Bolten, which have been all but un-

known for over a century.

The genus Colubraria is made the type of a new family Oolubrariide,

which, however, is not defined. Colubraria is as yet unknown ana-

tomically. We have elsewhere shown that, as limited by Dall, the

family is a mixture of Buccinid@ and Muricide, with possibly an-

other, but still unknown, element in the typical Colubrarias.

The essay, though not lengthy, will be read with great interest by

those who make a study of molluscan nomenciature. The eminence

of its author, both in the field of malacology and of general zodlogi-

cal nomenclature, will ensure a thorough consideration of the posi-

tions taken, by those competent to deal with sucht questions—

HA. Pe

Nores ON THE PLEUROTOMIDA, with description of some new

genera and species. By Thos. L. Casey. (Trans. Acad. Sci. of St.

Louis, XIV.) Mr. Casey proposes a new classification of the family, -

establishing eight ‘ tribes ’’ based chiefly upon characters of the

sinus. The consideration of genera is confined mainly to those rep-

resented in the American tertiaries, some 20 new genera being

erected. Numerous new Eocene species are described, chiefly from

Alabama and Texas. A single new recent species, Helenella insolens

from St. Helena, is described. Mr. Casey subdivides much more

minutely than has been the custom in this family, raising nearly

every group to generic rank. While “ genera” and ‘“ subgenera,”

etc., are essentially conventional, varying in rank with every investi-

gator, yet minute subdivision may easily be carried too far for prac-

tical convenience by reason of the great number of species likely to

‘ be found to fall between such narrowly restricted groups, requiring

the formation of still more new ‘‘ genera.”” The characters of the

protoconch are extensively used. This is perhaps the most valuable

feature in the paper, as they have not hitherto been adequately

studied in the Pleurotomidz generally. The genus Donovania, in-

cluded by Mr. Casey in the Plewrotomide, has been shown to belong —

to the Rhachiglossa.—H. A. P.

THe Errect OF THE BassiANn IstHMmus upon the existing ma-

Linn. Soc. N. S. Wales, 1903). A 35-fathom line on either side

would bound a submarine plateau 80 to 90 miles wide, stretching

from Australia to Tasmania. Mr. Hedley considers at length the

great faunal difference between the South Australian and East Aus-

tralian coasts, concluding that the faunal evidence indicates that Bass’

Strait was bridged until recent times by an isthmus. The deeply

dissected south coast of Tasmania indicates recent subsidence there

also, pointing to a former extension of Tasmania southwards, thus

separating what he terms the Adelaidean from the Peronian or tem-

perate East Australian faunas, by a promontory extending into de-

cidedly colder waters. The ideas advanced are well supported and

supply a beautifully simple explanation of the long-known and

hitherto unexplained diversity of the South Australian and Victorian

marine faunas.—H. A. P.

_ ADDITIONS TO THE MarINE MO.Luiuscan Fauna or NEw ZEa-

marks that ‘the fauna of the continental shelf of New Zealand is

New Zealand and Australia, hitherto calculated on the beach fauna,

will be disproportionately increased when the fauna of the conti-

nental shelf is taken into consideration.’”? Besides new forms of

several genera, Hedley describes a new genus of the Carditide, Ver-

ticipronus. The valves are small, smooth, and capped by a flat pro-

dissoconch. Another new genus, /neisura, is erected for Sctssurella

lyttletonensis Smith. This little snail is shown to belong to the

Fissurellide, having characters similar to the very young of Ms-

suridea. The specimens we have examined bear out Mr. Hedley’s

interesting conclusion. Jnezsura is apparently the most primitive of

existing Missurellide.—H. A. P.

A New ASHMUNELLA FROM NEw Mexico. By Paul Bartsch

(Smithsonian Misc. Coll., vol. 47, 1904, p. 138, 14). A. townsend:,

described from two specimens collected by Mr. C. H. S, Townsend

on the slopes of the ridge on the south fork of Ruidoso river, about

five miles above the town of Ruidoso, at an altitude of 8,500 ft.

This is in the Sierra Blanca, Mescalero Indian Reservation, Lincoln

Co., New Mexico. ‘ Ashmunella townsendi is most nearly related

to A. rhyssa Dall, but is much smaller than that form and is uni-

formly more strongly sculptured.” It measures, alt. 8.2, diam. 15,

width of umbilicus 2.3 mm., being thus larger than A. altissima

Ckll. from the summit of Sierra Blanca. From an intermediate

altitude, A. townsendi seems to be also intermediate in characters

between rhyssa and altissima. The use of the term ‘“ axial ” to de-

scribe obliquely radial sculpture seems rather forced. The direction

of such sculpture approaches ‘ axial ”’ only at the periphery, and it

is presumed that by ‘‘ axial ’’ is meant ‘in line with or in the direc-

tion of the axis ” as the Century Dictionary expresses it.

SHELLS oF Lanp AND WatTER: a familiar introduction to the

study of Mollusks. By Frank Collins Baker (Chicago, A. W.

Mumford, large 8vo). As its title indicates, this book is for the use

of those beginning the study of shells, and is especially designed to

be placed in the hands of young people interested in nature study,

but without much or any previous acquaintance with mollusks.

The chapters on The Home of the Clam, Pond Snails, Snails of the

Forest and Field, The Oyster and its Relatives, The Cowries, etc.,

afford an attractive insight into the mysteries of these creatures, and

will be a revelation to many intelligent people to whom shells have

had no meaning. Eight full-page colored plates are very good ex-

amples of the new “ three-color process,”’ and illustrate many of our

native species besides numerous exotic shells. These figures will

help many a learner to some knowledge of common “ mantlepiece ”

shells. The text is also fully illustrated with wood-cuts and half-

tone engravings, and a good deal of attention is given to the obser-

vation and collecting of mollusks. ‘The work is written in the some-

what old-fashioned form of a series of discourses or monologues by a

professor to several pupils. It is well gotten up typographically.—

PANOPEA BITRUNCATA CONRAD.

BY CHARLES W. JOHNSON.

The shell of the genus Panopea, like most of the burrowing

Pelecypods is subject throughout its growth to considerable variable-

ness. The causes of mutation are so admirably described by Dr.

Dall’ that I quote in full the following paragraphs :

*¢ All boring mollusks in which the shell has so degenerated that

it no longer covers the whole adult animal when retracted are more

liable to variation in minor details than those in which the valves

meet distally, and dynamically influence their own development by

fixing for it certain definite limits. This is markedly the case in the

present genus, Those shells which live in an easily movable

medium, such as sand or fine, soft mud, are thinner, better devel-

oped, more elongated and less distorted than their congeners who

are obliged to confine themselves to a gravelly or stony situs. So

marked is the difference that I] have several times been presented

with supposed new species based on these dynamic characters, and

by a curious reversal of logic, have been assured that the differences

must be specific, because the animals inhabited, respectively, the

different kinds of ground alluded to.

_‘**T have observed, also, that where the eround into which the

burrowers retire is a comparatively thin coating over a stony or

rocky layer which they cannot pierce, the tendency in Panopea,

Mya, ete., is for relatively short and broad shells, with shorter

siphons, to survive ; which naturally have a wider, shorter, and more

rounded pallial sinus, and shorter and more incurved nymphs. I

believe the influence of environment is direct-and not selective; at

all events the association of sz¢tus and specimens so characterized is,

as far as I have been able to determine, quite uniform, whether

selective or not.”

While living at St. Augustine, Florida (1880-87), I was fortu-

nate in finding in the harbor, on a sand bar near ‘+ Marsh Island,”

a specimen of Panopea bitruncata with valves intact, and from which

the animal had apparently just been removed. This spetimen which

is shown on plate IV, represents a nearly normal shell (reduced about

one-fifth) with the lines of growth but slightly interrupted anteriorly.

It had probably grown under favorable conditions in the adjacent

sandy-mud bottom. The shell measures 133 mm. (5.25 inches) in

length, with a width of 80 mm. On the ocean beach I also found

several single valves; these were proportionately shorter, and wider,

giving them a more truncated appearance. In my list of the shells

of St. Augustine, Florida, in this Journal, Volume IV, page 4, I re-

ferred these to Glycimeris bitruncata Conr., while in naming the one

from the harbor, I followed Dr. Dall’s catalogue of the shell-bearing

mollusks of the southeastern coast of the United States (Bull. 37,

U.S. Nat. Mus.) and called it G. reflexa Say.

Since Dr. Dall’s review of the species (Trans. Wagner Free Inst.

Sci. Vol. III, pl. 4, p. 831), I have made a careful study of the type

of P. bitruncata in connection with all recent specimens obtainable

and find no greater variation than exists in the Pliocene specimens of

Florida. The type of P. bttruncata is an injured specimen; the

upper or dorsal portion of the posterior end being broken away,

gives the shell a very oblique truncation, while the lower portion of

the anterior has been frequently arrested in its development, the

lines of growth being interrupted and crowded together, gives that

end also a very oblique outline. The umbonal and younger portion

of the shells are alike in all the specimens I have examined.

Uniting the recent and Pliocene forms, and adopting the oldest

name will make the synonomy stand as follows :

Conrad’s description of this species is very meager. No dimen-

sions are given and the only real specific character indicated is ‘ the

numerous, radiating, prominent lines.’’? Subsequent authors have

supplied no additional information except Haldeman, who gives a

figure, though, curiously enough, he states in the text that the species

is unknown to him, No specimens from the original locality, the

Black Warrior River, have been accessible to me. The only ex-

amples seen are two lots in the Lewis collection, so labelled by him,

one from the Coosa and the other from: the Cahawba River, Ala.,

and a set. from the latter stream collected by Call. Dr. Pilsbry has»

kindly compared these with the type specimen in the collection ‘of

the Academy and writes that though less strongly striated radially,

‘they agree with the type in form, and the almost invariably red

apex.” A ore bie) |

As evidenced by these shells, A. filosus closely resembles in shape |

-and contour the eastern form of A. tardus. It differs, however, in

the light green color, the radiating ribs and, when present, the rosy

apex. In none of these shells are the ribs very strongly developed,

nor do they extend uniformly over the shell from apex to periphery.

But there are indications of them on all. They are usually more

conspicuous on the sides, especially immediately below the apex and

toward the anterior slope, the central portion of the side slope being

comparatively smooth. Between these heavier ribs:‘are usually

several smaller ones, which seem to be extensions ‘ofthe apical

striz. The larger ribs are heavier and coarser than those noticed in

any other species and, when fully developed, would be‘ very promi-

nent’’ and conspicuous. The anterior slope is usually strongly con-

vex, although, as shown by the figures, there is some variation in

this particular; the posterior slope is nearly straight and direct, not

very oblique, and the side slopes are slightly convex. The marginal

outline varies from a regular oval to obovate with the greatest width

behind the apex. |

The Cahawba River specimens are thinner and more translucent

than those from the Coosa and are apparently less typical, being less

elevated, with the anterior slope more oblique.

The apex is much eroded in all of the Coosa specimens, but is

nearly perfect in those from the Cahawba. When perfect it is

‘Ssomewhat inclined” or rather flattened posteriorly, and very

slightly inclined to the right. Binney and Tryon are consequently

in error in referring the species to Acroloxus ( Velletia), whiclnis a

European group not represented in our fauna. 6 EEO,

IV. Ancylus parallelus Hald. (1841). Pl. 5, figs. 1-9.

This common and well-known species has a wide range througli

the northern states and Canada, extending from Nova Scotia and

New England to Manitoba and Minnesota. It is peculiarly a north-

ern form, and its range toward the south is comparatively limited.

Rkode Island, Central New York, Northern Ohio and Indiana, so

far as the records go, seem to mark the limit. It is not listed from

Philadelphia (Shick) nor Alleghany Co., Pa. (Stupakopf), nor

Cincinnati (Harper and Wetherby), nor the Chicago Area (Baker).

Mr. Marsh has kindly permitted me to examine the specimens

from Mercer Co., IIl., wich he quoted as this species in the

NautTivus III, p. 34, and they. prove to be a form of A. tardus,

Shimek’s citation from Iowa City, Ia., which shonld be verified, if

correct, probably marks its extreme range to the southwest, as it

does not occur in any of the Iowa lists nor in those of Missouri,

Nebraska or Kansas. The tentative citation of this species from

North Park. Col., by Ingersoll (Rep. U. S. G. & G. Surv., 1874,

p- 405) must also be considered very doubtful.

It is easily distinguished by its narrow, elongated shell, with

nearly straight lateral margins, which widen more or less anteriorly.

The anterior slope is typically (fig. 1) only slightly convex, but there

is considerable variation in this particular; the posterior slope is

long, very oblique and nearly straight, the right slope is nearly

Straight, and the left slope slightly convex. The apex is sub-acute

and slightly turned towards the right, and is nearly in the centre of

the shell. Lines of growth well marked, but fine and irregular. It

is at times subject to considerable irregularity in growth, when living

on a small reed, the peritreme is concave at the ends (as noticed in

-A. fuscus) and the lateral slopes are noticeably more convex and the

apex less prominent. Several examples have been noticed, in which

the shell in the earlier stages was unusually narrow, but on ap-

proaching maturity, a sudden expansion of the entire margin took

place, resolving the peritreme to nearly its normal outline (fig. 4).

Specimens of extraordinary size (fig. 7), far surpassing those from

any other locality, have been collected by Nylander at Caribou, Me.

Specimens nearly as large (7.5 x 4.5 x 3) have been collected by

Ferriss on the north shore of Lake Superior. Fine specimens

larger than the average also occurred in Schuyler’s and Little Lakes,

N. Y. (fig. 4). In most places, however, the average length is less

than 6 mm. A. parallelus is one of the few species of Ferrissia that

by preference chooses the quiet waters of: the: inland lakes for its

home. In northern Michigan, where it is the only species found, it

is abundant on the under surface of the lily pads and on the round

reeds (Scirpus lacustris), growing in water 3 to 6 feet deep. .

V. Ancylus haldemant Bat. (1844). PI. 6, figs. 9-13.

Haldeman’s types of the species, for which he used the preoccu-

pied name of depressus, came from the headwaters of the Holston

River, in Washington County, Virginia, and are now in the collec-

tion of the Philadelphia Academy. Dr. Pilsbry has kindly fur-

nished the accompanying outlines of the larger of the two specimens

(figs. 9, 10), and states that ‘ the base is a little raised at the ends,

but very slightly so, so that the growth-lines appear nearly straight.

There are some coarse radii, especially on the long slope, but not

pon ece ne over the whole surface, but the apical tract is beautifully

striate.’

I have referred to the species a small series collected by Hea.

hill in the Doe River at Roan Mountain Station, Tenn. As shown

by the figures (figs. 11— 13), they agree quite exactly with the type.

The specimen figured is decidedly obovate in its marginal outline,

the greatest, width being behind the apex, but others are more regu-

larly. oval.

It is a well- marked form, and, as stated by Haldeman, differs

from both rivular’s and tardus in the obtusely rounded apex, which

in the Doe River specimens is directed nearly straight backwards.

In the type specimen, it is apparently more excentric. There is no

indication in the Doe River specimens of the “ coarse radii ” which

are present on the type, but merely a slight rippling of the anterior

slope. But this, no doubt, is a variable feature. The specimen

figured is slightly longer and proportionately wider than the type;

the dimensions being : Length 4.43, breadth 3.33, alt. 1. 5 mm.

Museum of Natural History in New York City, I have’had the

opportunity of examining an author’s example of this rare species.

This specimen, though not quite as large as the type, agrees with

the description in all other particulars. The locality is given as

Kentucky and there is but little doubt that it is one of the original

lot. ;

It is a remarkably strong, heavy shell, as compared with the other

eastern species, and differs from them all in its size, greater eleva-

tion and the convex outline of the posterior slope. The marginal

outline is broadly oval, the greatest width being behind the centre

and immediately under the apex. The apex is quite acute and

turned toward the right. The apical striz are strong and close to-

gether at the apex, but rapidly diminishing in size, and the strong,

irregular lines of growth on the outer half of the circumference are

scarcely more than rippled by the radial lines. The apical portion

of this specimen was quite heavily encrusted with lime, which I did

not attempt to remove, and which covered up any indications of the

rosy color mentioned by Anthony in his description. The irregular

shape of this specimen is no doubt an individual peculiarity, caused

by a change in the line of growth after a period of rest, possibly a

change in the object on which the shell rested. Down to the line

where the new growth began, the outlines are quite regular, but be-

low it, there is first a decided constriction, rather more marked in

the posterior and left slopes, and then a rapid expansion all around

the circumference. Similar instances have already been described

as occurring in A. parallelus. The dimensions of this specimen are:

Length 5.75, breadth 4.5, alt. 3 mm.

Accompanying this shell were two smaller ones of evidently a dif-

ferent species, apparently the same as that found by Hinkley in the

Ohio River, and which will be more fully described in connection

with that form. In Mr. Hinkley’s collection is a single specimen of

the genuine elatzor, which was collected by him in a creek near Flor-

ence, Ala. The apex is badly eroded, but the rosy tinge is very

evident. Its dimensions are: Length 5, breadth 4.8, alt. 2.5 mm.

The outline is entirely regular without any trace of the constric-

tion shown in the Anthonyan specimen.

species in addition to that afforded by the original description, . It is

apparently a errissia,and distinguished from the other northern

Species by *‘ the delicate ribs,;which radiate from the apex to the

periphery of the shell.” Judging from the figure, the shell widens

posteriorly and not anteriorly, and the apex is turned to the right

and not, as stated by the author, to the left. Whether this be so or

not, the broadly ovate shape forbids its reference to the section

Acroloxus ( Velletia), made by Binney. Clessin’s remark that the

form of the apex as shown in Binney’s figure recalls the European

forms belonging to Ancylus s. s. seems equally untenable.

VIII. Ancylus borealis Morse (1864). PI. 6, figs. 14-16.

I have not been able to get any authentic specimens of this species

for examination. Its, main characteristic is stated by the author to

be the ‘‘ fine regularly interrupted, radiating lines (which) mark the

surface of the shell from the apex to,the border.”? Otherwise ‘ the

species resembles A. tardus in its general form.”’

The only specimens, at all referable to this species, which 1 have

seen, are those from the St. John’s river at Fort Kent, Me., men-

tioned by Nylander (Naurt., XIII, p. 105), one of which is figured.

They are quite close to A. tardus and possibly should be referred

to that species, but they are narrower and more elliptical than

the form of tardus, which is apparently prevalent in that State. The

growth lines, especially near the apex, are quite strong, and where

these are crossed by the apical striae, the effect is that of ‘fine inter-

rupted radiating lines,’’ but this is confined to the apical region. The

remaining surface of the shell is irregularly rippled in the manner

noticed in nearly all the American species. In view of the fact that

in many of the species where it occurs, the radial character (except

at the apex) isa variable feature, the reference of these examples to

A. borealis seems fairly justified. ‘The dimensions of the specimens

before me are as follows:

Length (fig. 14) 3.75, breadth 2.33, alf. 1.25 min.

Length 3.33, breadth 2.10, alt. 1.25 min.

Length 3.50, breadth 2.00, alt, 1.83 min.

Length 4.00, breadth 2.50, alt. 1.40 min.

Compared with the dimensions of the type, these shells are slightly

narrower and not quite as high. But the difference is so slight as to

be easily within the lines of individual variation.

The apex is very obtuse, being almost flat-on top when viewed in

profile.

Shell elevated, thin, transparent, horn-colored, with a yellowish-

brown epidermis; aperture ovate, conspicuously wider anteriorly, in

many (especially young) specimens slightly reniform by a barely

perceptible incurving of the right margin, the anterior, left and pos-

terior margins regularly rounded, the right slightly incurved,

straight, or but slightly convex; apex somewhat acute, elevated,

strongly depressed posteriorly and to the right, and curved down-

ward, in most specimens quite overhanging the posterior right

margin of the shell; the apical portion of the shell (one-half or more)

is strongly lateraliy, or rather obliquely, compressed, a character

which makes the young appear proportionately much narrower than

the adults; the posterior slope of the shell is long and strongly con-

vex, the posterior being short and concave. The surface is marked

~ by fine lines of growth.

Largest specimen: Length 3.5, width 1.8, height 1.2 mm.

Average dimensions: Length 2.7, width 1.7, height 1.2 mm.—

As the Bulletin, in which this species was described, is very

scarce and out of print, it seems better to reproduce the original de-

scription, which is very full and accurate, than to present a new one.

The only specification to be added being that the apex is radially

striate.

Through the kindness of Prof. Shimek, I have before me part of

the original lot collected by him in Deadman’s Run, near Lincoln,

Neb. It has also been found at Calloway, Neb., living on Cerato-

phyllum demersum 1, In the collection of the Philadelphia Academy

a single immature specimen was detected in a vial of A. rivularis

from the De!aware River at Philadelphia (No. 75811). These are

the only authentic records known to me. The tentative reference of

this species to Gundlachia by Pilsbry (Naur., IV, p. 48, and IX,

p. 63), was based on a misapprehension of the species, which is

quite different from the Rock Island, Ills., examples figured by him.

82 THE NAUTILUS.

The reference of the specimens from Rock Run, Joliet, Ills., to this

species by Baker (Moll. Chic. Area, p. 306), is erroneous for the

same reason.

The A. shimekii is a very distinct, little species, and, when once

seen, is not likely to be mistaken for any other. The high, narrow

shell with the rapid expansion towards the base; the prominent,

excentric, deflected apex, almost reaching the posterior margin, the

long convex anterior slope, and the peculiar posterior slope are very

characteristic and separate it from all the described species. It is

more nearly related to the small Ohio species, called pumilus by

Sterki, than to any other, but is bs hur distinct as panied out under

that species. ¥,

The specimen figured, the abate received from Shimek, is

slightly smaller than the average size as stated in the original de-—

scription, being:

Shell small, thin, translucent, shining, horn-colored ; oval or

curved ; apex radially striate, prominent, rather obtuse, not depressed

at the tip, about half way between the central and posterior margin

and decidedly turned to the right; anterior and left slopes very con-

extended range. Examples have been seen from the following

localities: Alexandria, Wa., Seneca, N. Y., Vermilion River, O.,

anterior slope only slightly convex, seem’to be also referable to this

species.

Distinguished primarily by its small size, this species is well char-

acterized by the prominent, obtuse apex, the short, straight posterior

slope and long, convex anterior slope. It is very close in general

appearance to A. shimekii, but seems to differ persistently in having

the apex, which is less excentric in position, ‘projecting decidedly

upwards and not depressed at the tip as in that species, the anterior

slopes not quite so convex, while the posterior slope is longer, more

oblique and nearly straight. The extreme lateral compression char-

acteristic of shimeki is not present in this species, the right slope

being nearly straight ; this difference is particularly marked in the

immature shells, which in shimeki are decidedly narrow and pro-

portionately higher than the mature shell, while in pwmalus the pro-

portions are nearly the same. Sterki’s types are immature examples,

to which his statement, that “ the sides aré parallel,’ is quite appli-

cable, but in mature examples the lateral margins expand a little and

become more curved as shown in the figure, which is from one of the

largest specimens seen, the dimensions being :

NOTES AND NEWS.

Mr. A. A. Hinkley is making a collecting trip to Alabama.

Epirors NAUTILUS:

In the course of some remarks on the “ Museum Boltenianum,”

Dr. Pilsbry in the October Nautiius refers to the ‘** free use of

polynomials ” in that work, citing some supposed examples, and sug-

gesting that no one who could ‘‘ swallow these ought to choke over

Chemnitz.”

The general question of the acceptability of Bolten’s work is too

large to enter upon here, and I believe it has been practically settled

in a sense adverse to the arguments I used twenty years ago, and

which Dr. Pilsbry now reiterates. But the matter of “ polynom-

ials ”’ can be settled right here. Bolten used polynomials as much

and no more than Linné and Gmelin, 1758-1792. Let us remember

that Bolten’s work was a posthumous MS. printed without revision

by the writer. It contains 2409 entries of species. Of these 64 are

what Dr. Pilsbry refers to as ‘ polynomials.” (The *‘ Murex mitra

episcopalis,” by the way, is not one of them, and does not occur in

the book as far as I can discover ; ‘* Mitra episcopalis”’ is there all

right.)

Now Bolten’s polynomials are partly hyphenated ; part of them

are words which we now combine in one word (as ‘‘ mille puncta-

tum"’); a lot of them are taken from Gmelin or Linné (as ‘“‘ caput

serpentis,” ‘ lingua felis,”’ etc.), and have always been in use; others

are geographical (as *‘ Nove zeelandiz,” ‘Bonz spei’’), and have also

been in use continuously to this day; all of them are either sub-

stantive phrases like ‘* pes-asininus,’’ or adjective combinations like

“‘ atro-viridis,” which we now use and write as one word. In the

whole sixty-four there is only a single case where something like a

Chemnitzian polynomial occurs, when to the name of the shell

‘* snistrorsa ’’ is added; indicating that the specimen was reversed.

Now exactly such polynomials occur in the work of Linné and most

of the older writers after 1758, and have been accepted as valid

without demur. Even D’Orbigny as late as 1853 indulged in at

least one. While we may regard them as awkward and objection-

able, they are not incompatible with the Linnean nomenclature, and

have never been so considered.

The polynomials of Martini and Chemnitz, on the other hand, are

simply descriptive phrases or brief sentences ; the dwindled rem-

nants of the earlier ‘* nomen triviale’”’ of pre-Linnean authors, and do

not come under the same class as those above cited from Linné and

Bolten. In short, with access to the book and a little comparison,

Dr. Pilsbry could soon satisfy himself that, on the score of regular

nomenclature, there can be no possible objection to Bolten.

NEW FORMS OF POLYGYRA FROM ALABAMA.

BY GEORGE H. CLAPP.

Polygyra (Stenotrema) barbata n. sp.

At first glance this species would be readily taken for P. steno-

trema and as it may exist in some collections under that name it can

best be described by comparison with that well-known and widely

distributed species.

Viewed from above, the difference is at once apparent, as barbata

has stiff hairs about 4 mm. in length which are widely spaced, and

the diagonal series cross the lines of growth at nearly a right angle.

The upper half of the outer lip is well reflected, not appressed as in

stenotrema and there is a distinct constriction back of it. From below

the difference is still more striking, as the width of the mouth in barbata

is fully double that of stenotrema; in barbata the width, measured

from the top of the tooth to the edge of the lip just below the notch,

is 1 mm., while in a stenotrema of the same size it isonly about $ mm.

The lamelliform tooth is more sinuous and less massive. The flat-

tened upper lip, which is markedly concave, has a well pronounced

tooth just opposite the upper end of the abruptly truncated parietal

tooth. The ‘ fulcrum,” which is plainly visible through the shell, is

the most pronounced feature, as it is 3 mm. in length, extending from

the axis fully half way across the body-whorl. - Embryonic whorls

polished and obsoletely ribbed, while in stenofrema they are granula-

ted. The granulated embryonic whorls of stenotrema and its allies,

would seem to make the section Stenotrema of at least subgeneric

value, although the almost smooth apex of barbata indicates that

there is some variation in the group. The young of barbata are

umbilicate. In size there is a wide variation in this species but in

all other particulars the characters are absolutely constant.

Greater diam. 11, lesser 10, altitude 7 mm.

Greater diam. 10, lesser 9, altitude 64 mm.

Greater diam. 8, lesser 74, altitude 54 mm.

The average diameter is 9 to 10 mm. Whorls about 54.

Types from the flood-plain of the Tallapoosa River near the Mont-

gomery Road about five miles southeast of Wetumpka, Ala., in col-

lections of Geo. H. Clapp and Acad. Nat. Sci. Phila.

This most interesting species was first found by Mr. Herbert H.

Smith in November, 1903, and he reports it scarce and apparently

very local.

On Poole’s Island in the Coosa River just below the Georgia line,

in Alabama, Mr. Smith found a smaller form of barbata which

differs slightly.in the mouth being still wider and the lip notch

weaker. It averages from 8 to 9 mm. diam.

Polygyra stenotrema seminuda n. var.

In the Proceedings of the Academy of Natural Sciences, 1900,

page 129, Dr. Pilsbry defines P. stenotrema var. nuda as follows:

“ Surface without hairs or their scars; other characters of typical

stenotrema.””

Among the shells collected by Mr. Herbert H. Smith in Central

Alabama is a variety of stenotrema which differs from nuda in having

very short, widely spaced hairs, in other particulars agreeing with

var. nuda. As it appears to be a ‘‘ connecting link,” I have called

it var. seminuda. In size it varies from 5? x 8 to 7 x 10 mm., the

average diameter being 9 to 94 mm.; color from greenish-white, al-

most albino, to dark reddish-brown. ‘Types from Bangor, 4 miles

north of Blount Springs, Blount Co., Ala., in coll. G. H. C. and A.

Nike

Mr. Smith has sent in three or four apparently well-marked varie-

ties of stenotrema, but it will be well to await the conclusion of his

work before attempting to define these local races.

NEW SPECIES OF BUCCINUM FROM THE KURIL ISLANDS.

BY H. A. PILSBRY.

Buccinum inclitum n. sp.

Shell ovate-pyramidal, solid, cream-colored with a few incon-

spicuous reddish-brown stains. The spire is straightly pyramidal,

the apex small, the first whorl wanting in the type specimen. 8

whorls remain; they are very convex and separated by deep, chan-

nelled sutures. Below the suture the flattened, sloping surface is

sculptured with four or five spiral cords. These are followed by

three very strong spiral ribs, separated by deep striate intervals.

On the last whorl there are four large ribs, grouped near the

periphery, which is formed by the second rib; below them tiie base

has about 8 gradually decreasing spiral cords, with one to three

smaller cords and threads in each interval, exclusive of those on the

convex, siphonal fasciole. Over the whole of this sculpture there is

a very fine spiral striation, and the upper slope of the whorls has

small radial waves, making the ribs slightly nodose. The aperture

is tinted with pale yellow on both lips, the outer lip being somewhat

expanded, and posteriorly flaring. The anterior canal is short and

wide.

Length 82, diam. 46 mm.

Etord, Chishima [Kuril Is.]. Type is no. 88768 A. N.S. P.,

from no. 1704 of Mr. Hirase’s collection.

This noble and beautiful species is somewhat related to B. leuco-

stoma and B. martensianum, but it is much more strongly sculptured

small number of spiral keels.

Bucecinum chishimanum n. sp.

Shell ovate, rather thin but moderately solid, yellowish olive-

green, the principal spiral ribs typically red-brown with light spots.

Spire slate-blue or ashy-purple. Whorls 6, the apex slightly

mamillar and smooth, the last whorl ventricose, sculptured with

numerous very unequal spiral cords and threads, the larger cords

widely spaced on the upper half, more numerous below. Over all

there is a microscopic sculpture of distinct, fine and close fold-like

growth-striz, and very fine, subobsolete spiral striz. The suture is

bordered with weak folds, sometimes stronger and tubercular. The

aperture is half-round, glossy, dark clestnut-brown inside, the

bevelled and slightly expanded lip cream-white. The basal notch is

rather wide and not very deep.

Length 31, diam. 20 mm.

Etor6é, Chishima (Kuril Is.), types no 87757 A. N.S. P., from

no. 1597a of Mr. Hirase’s collection.

This whelk seems to be related to the smaller, thinner and

}

smoother B. mdrchianum (Fischer), but the two are quite distinct.

In some specimens the coarser spirals are all low, subequal and

almost evenly distributed over the surface. As usual in Buccinum,

the coarser sculpture is variable. Some specimens lack the thin,

greenish cuticle, being dull, creamy-ashen, like many arctic shells.

There is always a livid or purplish worn spot in front of the aper-

totes,

ON THE NORTHERNMOST HABITAT OF LIGUUS FASCIATUS ON THE

FLORIDA EAST COAST.

BY CLARENCE B. MOORE,

These snails at the present writing (1904), live in great abund-

ance at Miami, Dade Co., Florida. They were found by me in

small numbers at Arch Creek, about nine miles north of Miami.

Going northward I found them, here and there, along the banks of

New River, below Ft. Lauderdale about 24 miles, in a straight line,

north of Miami. 7

North of this point inquiries were made along the banks of the

canal where ‘‘ hammock ” land (such as Liguus requires) is often in

sight, but in no case had the snails been seen by the inhabitants,

At Boca Raton, Dade Co., the hammock is not large, and much

undergrowth has been burned recently. We saw no living Liguus,

nor any of their shells on the ground. Glandina was present and

various shells of other kinds.

Occasionally among the Keys, south and east of the peninsula, the

statement was made to me by persons I met, that occasional snails of

this species had been seen by them as far north as Lake Worth.

A number of inhabitants living about six miles south of Lake

Worth had never seen the snails. Around the southern end of Lake

Worth there is much fine hammock, where the vegetation seemed

expressly made for Liguus, but a careful search made by my party

TIE NAUTILUS. 89°

yielded no evidence of these snails on the trees or of their shells on

the ground. Glandina and many smaller snail shells were found.

When I reached Palm Beach, on Lake Worth, I called on a

dealer in shells, who told me he had sold many Liguus from Miami,

but had found none around Lake Worth. He said he had placed a

number of snails from Miami around Lake Worth, in the hammock,

but the snails died.

At present, therefore, New River is apparently the northern limit

of Liguus on the East Coast; and satisfactory evidence is lacking that

it ever extended further north. .

NEW LAND SNAILS FROM NORTH CAROLINA.

BY H. A. PIESBRY.

Polygyru appressa tryoniana n. subsp.

The shell is imperforate, similar in shape to P. appressa; rather

dark greenish-brown ; very glossy. Sculpture on the last 4 whorls

of regular, fine, curved riblets, which are slightly narrower than

-their intervals, and fine engraved spiral lines, more prominent in the

intervals than on the ribs. The first (embryonic) 14 whorls are

densely sculptured to the apex with obliquely radial stria, followed

by a small fraction of a whorl with coarser, irregular striz before the

riblets set in. Spire convexly conic. Whorls 5} to 53, slowly in-

creasing, the last somewhat angular at the periphery in front. The

suture descends slightly to the aperture. The aperture is very

oblique, somewhat ‘‘ dished.’* ‘The peristome is very wide, strongly

thickened within, contracting the aperture, and broadly, flatly re-

flexed; white, with a fleshy outer border in all but old sheils. ‘The

back of the lip is bright yellow, this color spreading to form a tri-

basal lip, which lacks the long tooth of appressa and perigrapta, or

has only the slightest vestige of it. P. a. tryoniana differs from P.

wheatleyt in the more depressed body-whorl with a tendency to angu-

lation, the larger parietal tooth and especially in the sculpture. P.

wheatleyt has small sharp raised points scattered over the upper sur-

face and in the more delicate specimens upon the base also, and

while some spiral lines may be seen on the base in some specimens,

they are very weakly developed. In P. tryoniana there is no trace

of bair-bases or points, the sculpture being like that of P. appressa

perigrapta.

Polygyra wheatleyi clingmanica n. subsp.

Shell small, thin and fragile, somewhat transparent, pale. The

glossy surface is set throughout (except near the apex) with short

delicate hairs, readily removed and often in large part lost from old

or cleaned shells. The rib-striz of the typical form are much weak-

ened or nearly effaced. Lip narrow, no parietal tooth. Alt. 8.7

Nene the summit of Clingman Dome, Great Sake Mountains.

Types no. 77616 A. N.S. P., collected by Messrs. Ferriss, Clapp,

Walker, Sargent and the author, 1899,

This form was noticed by me, Proc. A. N.S. Phila., 1900, p- 127.

It seems sufficiently differentiated from the typical form of wheatleyi

from Cherokee Co., N. C., from the more solid form prevalent in

the Great Smoky Mts., generally, and from the form of Roan Mt.,

to require a special name. It was found from the summit of Cling-

man Dome to our camp at the ** Balsams,”’ near the western end of

the mountain. Lower down, the ordinary P. wheatley: replaces it.

It is analogous to P. andrewse altivagqa.

AGRIOLIMAX AGRESTIS IN COLORADO.

BY T. D. A. COCKERELL.

To-day, October 25, 1904, I was surprised to find Agriolmax

agrestis in abundance in a vacant lot in the town of Boulder, Colo-

rado. This is the first indication of the establishment of this slug in

the Rocky Mountain region. The specimens are much darker than

those one ordinarily finds in England, and those I collected are re-

ferable to the following mutations :

any distinct spots or lines. Sixteen specimens.

(2.) Mut. brwnneus, Taylor. Very dark-brown; one or two are

so nearly black that they could be taken for mut. niger, Morelet.

Hight specimens.

(3.) Mut. semtirufus, nov. Head and mantle rufous ; body poster-

jor to mantle almost black. Two specimens, ‘This indicates that

the coloration of the head and mantle, and that of the body, may be

separately inherited, though more frequently the color of the animal

above is uniform.

’ The common English forms pallida Schrenk, and _ reticulata

Muller, are absent.

MARGARITANA MARGARITIFERA IN PENNSYLVANIA.

BY CHAS. H. CONNER.

A few weeks ago, I had the pleasure of receiving a few specimens

of Margaritana margaritifera Linneus, which were taken from Still

Creek, near Quakake, Schuylkill Co., Pa. As I believe this species

of fresh-water mussels has not been reported living in Pennsyl-

vania, I send you this note. |

Mr. Frank M. Ebert. who kindly forwarded the specimens to me,

states that they are found in the several streams of the vicinity. He

and others have taken a great quantity of pearls of all sizes and

grades from them. ‘Though Mr. Ebert has collected the species for

some time, he informs me that he has never found a gravid specimen.

The foot and gills of the specimens examined are brownish, the

rest of the body being white.

NOTES AND NEWS.

ARION CIRCUMSCRIPTUS, JOHNS. (FASCIATUS NILSS., pars).—

Last June I found this European slug in abundance on Goat Island,

Niagara Falls, N. Y. It appears to be an addition to the fauna of

New York, but Dr. N. L. Britton. to whom I mentioned the occur-

rence, said he was sure he had heard some report of it. The speci-

mens were of the usual grey color, with narrow bands and a slight

keel. In 1887 I searched the same locality, but at that time the

Arion was apparently absent.—T. D. A. CocKERELL.

ALBINO POLYGYRA MONODON AND P. HIRSUTA.—I am sending

the white (albino) form of Polygyra monodon. which I have found

this season near Des Moines, Iowa. This white form is associated

with the ordinary brown ones, but I never find P. monodon near P.

monodon fruterna. P.m. fraterna and P. hirsuta I find associated.

I also have a few white P. hrrsuta.—T. Van HyNIne.

GEOGRAPHIC RANGE OF POLYGYRA TRIDENTATA DISCOIDEA IN

Inp1AnA.—I send you to-day specimens from Charlestown Landing

and Mt. Vernon of P. tridentata discoidea Pils. It seems that this

variety extends across the whole width of the State, for Charlestown

Landing is 50 miles above Louisville, Connelton, the original locality

PHYLOGENY OF Fusus anv Irs AL.Lies. By Amadeus W,

Grabau (Smithsonian Miscellaneous Collection [no. 1417] part of

Vol. XLIV, 1904).

This work represents a great amount of investigation and careful

study. <A pupil of the late Professor Hyatt, the author has applied

the principles of development, parallelism and acceleration in de-

fining genetic boundaries. In this group the author considers the

protoconch and nepionic stages of the conch to be the most important,

although not always to be relied upon, Parallelism is constantly

cropping out, ‘* but parallelism is no guide to affinity, and hence grave

mistakes in classification are made, unless this fact is borne in mind.

Parallelism is much more potent in the later stages of development

than in the earlier ones, although it is by no means unknown in

these latter.’ This and the following quotation briefly define the

author’s views :

‘“The Fuside as a group are highly accelerated, and near the

acme of development. Primitive types are uncommon, except in

the eocene and even there regressive species appear. ‘The majority

of species have attained the acme of development for the group, many

THE NAUTILUS. 93

of them reaching it while still young. * * Fusus colus, the type

of the genus, is itself a regressively accelerated type, in which the

characteristic acmatic features have nearly disappeared in the adult.

Excessive degradational acceleration is seen in Cyrtulus, Clavilithes

and similar genera.”

In the eocene of the Gulf States there is a group of shells having

the form of a true Fusus but with a protoconch similar to many

species usually referred to Pleurotoma. For such shells the new

genus Falsifusus is proposed. Type: Fusus meyeri Aldrich

(not Dunker). I beg to differ with the author in using /. meyert

Aldr. Lusus meyeri, being preoccupied, becomes a synonym and re-

mains a synonym; the name of /. otton’s Aldr. proposed in its stead

should be adopted. _

For two forms (fusus quercollis and F. rugatus) from the lower

eocene of Alabama, the name of fulgurofusus is proposed. The

protoconch is Fulguroid. The new generic name of Hedlprinia is

given to a number of recent and late tertiary fusoid shells from the

Antillean region and Florida. ‘ They differ from /Fusus in the very

remarkable, strongly accelerated protoconch, which is throughout its

greater portion crossed by riblets.” Type: Fusus caloosaensis

Heilp.

Under the head of Phylogerontic Fuside is placed the peculiar

Cyriulus serotinus Hinds. Its genetic relation to Clavilithes is dis-

puted ; in its young stages it is a typical Fusus, but in the adult the

whorls become thick and loosely wrapped about one another ; this

type of structure is designated as Melongenoid. To the eocene

forms which most closely resemble Cyrtulus, the new generic name

of Clavellofusus is given. ‘Genotype: Clavellofusus spiratus sp.

nov.’’ Under this genus are described three new species from the

Paris Basin, forms which are considered by most authors to be only

variations of the variable Clavilithes longevus Lam. The author

seems to have had very few specimens showing the protoconch on

which to base such novel conclusions. Under the genus Clavi-

lithes several new species are described, including C. solanderi, based

on the Murex longzvus Solander (in part) and including specimens

figured by Sowerby. (Mineral Conch. I, 141, tab. 63, f. 1, 1812).

It may be of interest to know that this identical specimen is in the

collection of the Academy of Natural Sciences, Philadelphia. It was

presented to the Academy by Dr. Thos. B. Wilson, who purchased it

94 THE NAUTILUS.

in Europe many years ago, together with several others illustrated in

the same work.

For another new genus derived in part from the genus Olavilithes

of authors, the name of Rhopulithes is proposed (** Genotype: Fusus

noe Lamarck”), while three new species have been found in the

gleanings from the Paris Basin. The generic name of Cosmolithes

is proposed for Fusus uniplicatus Lam.

It is not easy to define the true position of many of the genera.

Whether a Pleurotomoid or a Fulguroid protoconch should remove a

shell in every other respect a Fusus, from the family, or what posi-

tion a shell with the protoconch of a Fusus, but with the form of a

Hemifusus, should occupy, the author has not always clearly defined.

A table of genera showing their relative position to allied forms

would have been very useful and would more readily convey to stu-

dents the author’s conclusions.

The work contains 192 pages, including 18 plates. The two plates

of protoconchs are exceedingly fine, but the half-tone plates could be

improved upon.—C. W. J.

in nomenclature that should be adopted. The Strombus urceus

Linn. = S. floridus Lam. ‘The species commonly. known as S.

a group of Southwestern Helices, nearly all of which have been de-

scribed since 1890 ; and the foundation of the genus dates only from

1901. To the anatomical characteristics already known, Mr.

Bartsch adds a very useful conchological generic character, dis-

tinguishing tae genus from EHpiphragmophora: the shell of Sonorella

e never has incised spiral lines. The species are shown to fall into

groups according to the sculpture of the embryonic shell; the char-

acters and distribution of all of them are discussed more or less fully,

and the following new forms are described: S. ashmuni, S. dulli, S.

baileyi, S. buileyt oreut’, S. fisheri trom the United States, and S.

nelson’, S. goldmani, S. merrill, S. mearnsi from adjacent states of

Mexico. Six plates of illustrations represent all of the known

species and typical examples of the apices; all being reproduced

from photographs.

There will probably be some difference of opinion about the rank

given to the several forms described as species ; but whether they be

ultimately ranked as species or subspecies, Mr. Bartsch’s careful

work in discriminating the numerous forms gives the paper a high

value. It ought to be mentioned that the use made of Hyatt’s terms

of growth is almost throughout erroneous; but as this is in the

present case a mere question of descriptive terms, it does not

seriously detract from the value of the essay.—H. A. P.

West AMERICAN SHELLS. By Josiah Keep, A. M. San Fran-

cisco, 1904. Pp. 860, 304 figs. Twenty-three years ago Professor

Keep published a modest little book, ‘* Common Sea-sliells of Cali-

fornia.” This was the first successful attempt to popularize the

study of American mollusks. It was followed in 1887 by a more

extended hook, “ West Coast Shells,’? which also met with a cordial

welcome from advanced students and beginners in nature study

alike.

The edition of this book being exhausted, Professor Keep has pre-

pared a more extended work including descriptions and figures of

many more species, and a list of West Coast and Rocky Mountain

Mollusca. The descriptions are simply worded, and being supple-

mented by several hundred figures in the text, enable the western

student to identify and learn something of nearly all the shells likely:

erate depths. Lovers of shells everywhere, éven those not interested

in Pacific shells, will delight in the simple and direct English of the

book, and will find their knowledge of mollusk-life broadened by it.

There is a contagious enthusiasm in its pages.

So much good must .be said of Professor Keep’s book that we

hesitate to mention any defects. On p. 152, Physa ** columbella”’ is

a misprint for P. columbiana, and Aplexa is misspelled. Fig. 136,

on p. 154, is apparently Planorbis binneyi. Ancylus subrotundus is

a species of Lanz. Fig. 103, on p. 123, is Oreohelix haydeni, not

strigosa. ‘The species striatella and cockerelli are not Oreohelices.

Figs. 119 are not Ashmunella levettec. Various other errors occur

among the land shells. There are many wrong authorities given for

specific names, and the list at the end contains a great many errors

and entries of the same species under two or three names which

might have been avoided by submitting it to specialists on Molluscan

nomenclature. Such a check, to pick up loose ends, is necessary in

a work covering so wide a field, for part of which the author must

rely on published data of various periods and various degrees of per-

fection. Fortunately many of the errors occur in the list, rather than

in the main text of the work, which aside from these defects deserves

all the praise we have given it.—H. A. P.

ON AN INTERESTING FOSSIL UNIO FROM WISCONSIN.

BY GEORGE WAGNER.

A little over a year ago Mrs. George Marston, of Quincy, Illinois,

presented to the University of Wisconsin the mollusca brought to-

gether by her late husband, an ardent and an able collector of our

Wisconsin forms. The collection was placed in my hands for ar-

rangement. In looking it over I was immediately attracted by a

single somewhat broken valve of a Unio, evidently fossilized, and

the only fossil form in the collection.

Mrs. Marston had very kindly, and very wisely, sent with the col-

lection all of her busband’s correspondence relating to it. In look-

ing over the letters I came across a copy of one written by Mr.

Marston, and containing the necessary locality data for this shell.

According to this letter the shell was found about 1889 in the

city of Green Bay, Wisconsin, during excavations for the city water-

works reservoir. It came from a depth of about fifteen feet below

the surface, and presumably from the till. .

As Mr. Marston well knew, the shell-is wholly unlike any Unionid

‘now found in Wisconsin. It is a left valve, quite heavy but very

brittle. When found, the outer surface still retained most of the

epidermis, but this has almost entirely disappeared. Tlie height is

70 mm., the breadth of the single valve approximately 22 mm.

~* The shell when complete was very evidently smooth, with a rather

_ elliptical outline. Tlie wall is thick but thins down considerably

98 THE NAUTILUS.

toward the posterior end. Anterior margin incrassate. Posterior

dorsal curve regular and strong. Posterior umbonal slope flattened,

and separated by a decided angle from the lateral slope. There are

some traces of waviness on this posterior slope. The umbones are

not very prominent and but very slightly incurved; the ligament

long and heavy. The cardinal teeth, though much weathered, were

evidently short and heavy, the lateral teeth long and nearly straight. ”

The anterior adductor cicatrix is large and deep, strongly pitted ; the

protractor impression triangular, The pallial cicatrix is very deep,

and crenulate. Only a small portion of the posterior cicatrix re-

mains.

On comparing the valve with the Unios in our collection, ] am

forced to the conclusion that we have here a specimen of Unio crassv-

dens Lam. I am further strengthened in this belief on comparing

the specimen with the figures and description of U. crasstdens by

Call (a study of the Unionide of Arkansas, ete.—Trans. Ac.

Sciences, St. Louis, Vol. VII, pp. 1-65, plates I-X XI). Finally I

have compared it with two specimens of U. crassidens. one from the

Ohio river, the other from southern Michigan, which, were kindly

sent to me for this purpose by Dr. W. S. Strode, of Lewistown, IIli-

nois. It may be that further material will force us to recognize it

as a separate variety, but I do not think it probable.

Now let us consider the present distribution of U. crassidens.

According to Call (/. c.) it is abundant in the Cumberland river of

Tennessee as well as in other rivers of that State. It occurs

abundantly also in the Coosa and the Alabama, in the Tombigbhee,

and southeast to the Chattahoochee (Simpson, Synopsis of the

Naiades, Proc. U. S. Nat. Mus., Vol. XXII, pp. 501-1044). It-

also occurs in the Mississippi and its eastern tributaries as far north

as the forty-second parallel; or, in general, to northern Illinois and

southern Michigan. It does not occur within the Basin of the Great

Lakes, neither has it ever been found in any stream west of the

Mississippi so far as I know. We must look upon it then as essenti-

ally a southeastern form, with its center of distribution lying prob-

ably somewhere in the rivers of Tennessee.

_We are thus confronted with the problem of its occurrence, in

fossil form at Green Bay, in the St. Lawrence Basin. It is because

this involyes an interesting point in the causes affecting present

geographical distribution, that this note i3 written.

THE NAUTILUS; 99

One of the marked topographic features of Wisconsin is a long

diagonal valley extending from Green: Bay, and really as a continua-

tion of the basin of this bay, toward the southwest, It follows the

basin of Lake Winnebago and the course of the Fox river. In the

neighborhood of Portage it overrides the water-shed, and is con-

tinued in the valleys of the Wisconsin and the Rock. At Portage

the Fox and the Wisconsin are less than two miles apart, and in

Spring become confluent, the upper Wisconsin contributing largely

toward the floods of the Fox (Irving, Geology of Wisconsin, Vol.

II, pp. 418, 419).

Now, according to Irving (I. ¢. p. 426), it is very probable that

in preglacial times the entire area of the Fox river drainage, includ-

ing the basin of the Wolf, far north of Green Bay, was drained by

the Wisconsin, or a stream occupying approximately its bed. Given

this former unity of the Fox and the Wisconsin drainage, the oc-

currence of a Mississippi form as a fossil in Green Bay is made clear,

even though this form be now a southern one. For it must be re-

membered here that southern forms in general had a decidedly more

northern distribution before the Pleistocene, and especially before the

Pliocene. |

How as to its disappearance? We know that during the Pleisto-

cene the northern part of our hemisphere became ice-voated nearly

as far south as the Ohio river. One of the lobes of this great ice

mass entered this very same Green Bay—Wisconsin Valley—and

plowed through it nearly its entire length.

It is evident that this enormous ice mass swept everything living

before it, or buried it beneath, and Unio crassidens had to go with

the rest.

When the ice finally receded the conditions were so changed as

to forbid the establishment of previous faunal conditions. In the

first place, the drainage of the Fox was now separated from that of

the Wisconsin. But more important, the climate of this region had

become so much colder that many of the former inhabitants, U.

erassidens among them, seem not to have been robust enough to re-

gain even such part of their former territory, to which the waterway

was freely open. Finally alteration in tension between various

species probably also contributed to the same general result.

It is highly desirable that the Unionids, as well as other mollusca

found on both sides of the divide between the Mississippi and St.

100 | PHeE NAUTILUS.

Lawrence Basins be much more conipletely ‘studied, especially in

regions where the divide is narrow. Together with this we need to

obtain and study the fossil forms of the Tertiary and Pleistocene.

Thus and thus only can we get a much more accurate and detailed

knowledge of the effect of the Glacial Period on the distribution of

animals. |

ON THE SPECIES OF MARTESIA OF THE EASTERN UNITED STATES.

BY CHARLES W. JOHNSON

- Three species of the genus Mar/esia are found on the eastern coast.

of the United States. They are more abundant south of Cape

Hatteras, becoming less common or rare to the northward. Like

most burrowing shells they are subject to considerable variation.

There is also a great difference in appearance between the young

and adult shell, the large anterior gape of the young being closed in

the adult by a calcareous deposit called the ‘‘ callum ” attached to

either valve and extending to the middle or lower edge of the valve.

The shell has a large protoplax and a narrow elongated metaplax

and hypoplax ; mesoplax and siphonoplax wanting; valves with a

single radial sulcus. The species can readily be distinguished by the

form of the protoplax, which though showing slight variation, prob-

ably due to a favorable or unfavorable situs, is quite constant in its

general character.

sidered D. smithi?. During my residence at St. Augustine (1880-87),

I found a large number of fine specimens in a piece of soft artificial

limestone off the water battery of Fort Marion. In my list of the

shells of St. Augustine (THE Navutitus IV, 4) I confused this with

M. cuneiformis. This species has only been recorded from shells

and limestone while WZ. striatus and cuneiformis are more frequently

found in wood. Its occurrence as far north as New York is prob-

ably accidental.

NOTE ON THE NOMENCLATURE OF THE SNAILS USUALLY CALLED PUPA.

BY T. D. A. COCKERELL.

Since it appears that the name Pupa is not applicable to the snails

usually known as Pupa muscorum, blandit, etc., it becomes necessary

to determine what generic name they are entitled to. Mr. B. B.

Woodward has placed them in J/aminia, Risso, 1826, of which he

regards Pupilla, Leach, asa synonym. A study of Dr. Dall’s paper

in Nautixus, 1904, p. 114, convinced me that this conclusion was

not unassailable, and with the help of additional information very

kindly supplied by Dr. Dall, I have decided to my own satisfaction

in favor of Pupilla. The argument is as follows:

1. Jaminia, Risso, 1826, contained species afterwards referred to

Alga (1830), Abida (1831), Pupilla (1831), HEucore (1837), and

Sphyradium (1837). The first species is mdnutissima Hartmann, but

this does not agree with the generic diagnosis. The only figured

species is an Abida, or Hucore.

2. Alea, Jeffreys, 1830, contained among other things edentula,

Draparnaud (now referred to Sphyradium) and minutissima, Hart-

mann. The latter is taken as the type by Dr. Dall (t. c., p. 115).

Conchologically, minutissima has the characters of Sphyradium, and

not at all those of Vertigo, Pupilla, etc. Its reference to Sphyradium

104 | | THE NAUTILUS.

should be fortified by an examination of the Jaw and lingual mem-

brane, but for my own part, I am satisfied that it belongs there. If

this is confirmed, A/gxa takes the place of Sphyradium, Agassiz, 1837.

3. Abida, Leach in Turton, 1831, has for its sole example and

therefore type Pupa secale. Hucore, Agassiz in Charpentier, 1837,

was proposed for P. tridens and P. quadridens. I do not think these

can be regarded as different genera, but the characteristic European

group of ** Pupa

secale, P. tridens, P. quadridens, etc., surely de-

serves to rank as a valid genus, separate from the circumpolar group

commonly known as Pupa, subg. Pupilla.

4. If Alza = Sphyradium, and Eucore = Abida, all the species of

Jaminia were provided tor by 1831. If Sphyradium is distinct from

Alza, apparently the diagnosis of Jaminia prevents .us from. using

that name for Sphyradium.

5. Jaminia is therefore either Abida or Pupilla, both published in

the same work. Adbd¢da has in its favor the figured example ; Pupzlla

has Mr. B. B. Woodward’s decision. Apparently priority of place

should decide the matter.

6. Dr. Dall informs me that in Purton Fuge umbilicake is on

p. 98, P. marginata (our muscorum) on p. 99; Abida secale on p. 101

asasynonym of Vertigo secale(Draparnand) Turton. Hence Pupilla

was first removed, and Jaminia stands as the proper name for Adida,

with Hucore as a section.

7. Ido not think the status of Pupilla is affected if we regard

umbilicata as its type, for I cannot imagine any one could place

umbilicata and muscorum in different genera:

8. Our forms of Pupilla stand thus:

Pupilla muscorum (Linné).

b. unidentata (C. Pfr.).

c. bigranata (Rossm.).

Pupilla hebes (Ancey).

Pupilla blandi Morse.

b. sublubrica (Ancey).

NOTES ON THE NOMENCLATURE OF PUPILLIDE.

BY H. A. PILSBRY.

The receipt of an article from Professor Cockerell upon this sub-

ject. published in this number, causes me to insert lere some notes

which had been prepared for a forthcoming paper upon the snails of

Arizona and New Mexico. The status of the name Pupa was dis-

cussed by Mr. B. B. Woodward (Journ. of Conch., Oct., 1903, 358),

who did good work towards clearing the ground. ,. Dall in this jour-

nal for February, ’04, also went over the nomenclature correcting

some errors, but complicating the question by a few new ones. His

statement that ‘ Risso’s first species [of Jaminia] is Vertigo minu-

tissima. Hartmann, which should properly have been placed in Sara-

phia,” is not borne out by an examination:of Risso’s work, wherein

the species stand thus:

Risso’s species. | Equivalents in ordinary use. Modern genus.

All of Risso’s species of /aminia that are recognizable belong to

the subsequent groups Hna 1831, Pupilla 1831, Abida 1831, Eucore

1837, and Lauria 1840.

Now P. muscorum under the name marginata was second of the two

species for which the name Pupzlla was proposed in 1831 in Turton’s

Manual, the other being P. umbilicata. The latter was removed in

1840 to Lauria, leaving P. muscorum the type of Pupilla. There is

nothing especially new about this conclusion, since it was reached by .

Gray in 1847 (P. Z.S., p. 176), and has been held by Pfeiffer, by

Von Martens (Die Hel. 1860, p. 290), and nearly every one else.

There have been differences of opinion about the limits of the group

Pupilla, but never about its type. Among American writers, Morse

and Tryon have used Pupilla as a generic name.

Abida was next removed from Jaminia. This is the group com-

monly known as Torquilla, Then in 1837 Hucore was proposed for

the species tr?dens and quadridens (heterostropha Risso). These suc-

cessive eliminations leave only the group Lauria Gray, represented

by J. marginata Risso (= Pupa umbilicata Drap.) to bear the name

Jaminia.* s

From the foregoing it follows that the name Pupzilla will replace

Pupa, as Prof. Cockerell has held. The groups represented in

Jaminia Risso, will stand thus:

PupiLia Leh. in Turton, for Pupa of authors.

JAMINIA Risso, restricted, for Lauria Gray.

Ena Leach in Turton, for Buliminus Auct.

AsipA Leach in Turton, for Torguilla Auct.

Evucore Ag. in Charp., for Chondrula Auct.

All of these groups I regard as of generic rank.

As to Saraphia Risso, the only species of the group that has been

positively identified is S. tridentata, which is the Curychium tridenta-

tum of recent authors.

After a bout with Risso, one is likely to accept as a just one Bour-

guignat’s estimate of his abilities: ‘* Ecrivain fécond, mais sans juge-

ment, innovateur infatigable, mais absurde, Risso a embrassé dans

ses ecrits presque toutes les branches de l'histoire naturelle, sans en

avoir bien traité une seule.”

The group Alea Jeffreys, 1830, has been discussed by Professors

Dall and Cockerell, who agree that its type must be Pupa minu-

tiss‘ma Hartm. It does not do to fix types for these old groups

without reference to what has been done by our predecessors. Gray

and Herrmannsen took a hand in this game over fifty years ago, and

they expressly selected Alza pulustris = Vertigo antivertigo as the

* The progress of events had already restricted Jaminia before Gray chose J.

heterostropha for its type (P. Z. S., 1847, p. 176). His selection came too late

and is ineffective.

type of Alea. I do not see how their action can be successfully

opposed. The name A/za has quite generally been used for dex-

tral forms of Vertigo, and is so retained in Westerlund’s last Catalog.

No valid grounds exist for shifting the name 3 and the advisibility

of substituting Alga for Sphyradium, as Prof. Cockerell suggests,

need not be considered. His suggestion that P. minutissima may be

a Sphyradium is interesting, and deserves investigation.

Ptychochilus Boettger, is preoccupied by Agassiz in Pisces; : a fact

I neglected to mention at the time I proposed Nesopupa. ‘The names

stand thus:

Ptychocheilus Agassiz, Amer. Journ. Sci. and Arts, XIX, 1855,

p- 227.

Ptychochilus Jordan, Bull. U. 8. Nat. Mus. no. 10, p. 58 (1877).

Ptychochilus Boettger, Conch. Mittheil., 1881.

Bifidaria and Hubifidaria of Sterki call for some notice in view of

the note by Dall in Nauritus, Feb., 1904, p. 116. The original

species referred by Sterki to Bifiduria were Pupa contracta Say and

P. servilis Gld, from certain Mexican localities. For P. contracta

Sterki subsequently (1892) proposed the section Albinula, leaving

servilis the type of Bifidaria.

In January, 1893, Dr. Sterki proposed Hubifidaria with the type

‘ hordeacea Gabb,” by which he meant the form which I call Bif-

daria procera cristata. ‘This is demonstrated by his previous article

treating of ‘‘ hordeacea,” by his list of the preceding year, and by

the words of his diagnosis of Hubifidaria, ‘‘lamelle typical.”

The type of Hubifidaria is therefore P. hordeacea Sterki not Gabb

= B. procera cristata P. & V., and the group becomes an absolute

synonym of Bifidaria,’s. str. The true hordacea Gabb, which Dr.

Sterki demonstrably did not intend, belongs to a different genus,

Pupoides.

In conclusion I might say that the generic and subgeneric nomen-

clature of the United States forms, given in my catalogue of 1900,*

stands as there set forth with the single exception of the genus Pupa,

which now becomes Pupilla.

The family name having precedence for the group is Pupilidez

Turton, 1831.

NEW SPECIES OF PISIDIUM.

BY V. STERKI.

PisiDIUM LIMATULUM, N. sp.

Mussel small, inequipartite, somewhat oblique, well inflated,

superior margin slightly curved, angle at the scutum projecting and

rather sharp, at the scutellum rounded ; supero-anterior slope dis-

tinct, almost straight, anterior end a rounded angle situated low;

inferior margin rather well curved, posterior truncate; beak some-

what posterior, moderately large and projecting over the hinge mar-

gin, rounded or slightly flattened on top; surface dull to somewhat

shining with subregular, crowded, sharp strize very fine over the

beaks, becoming coarser towards the margins; color pale horn in the

adult, straw to whitish in younger specimens; shell rather thin ;

hinge comparatively stout, plate rather narrow ; cardinal teeth ; the

right slightly curved, its posterior end much thicker and grooved,

the left anterior slightly curved, the posterior oblique, long, more

projecting than the anterior; lateral teeth rather large, cusps pointed,

strongly rugose, and so are the grooves, the outer posterior in the

right valve comparatively long ; ligament moderately thick.

Size: long. 8, alt. 2.5, diam. 2 mill.

Habitat: Alabama: Calera, in the current of a creek, and pools

left on same; Town Creck at Montevallo; spring creek at Ebenezer

Church, a spring branch in Big Wills Valley, six miles south of

Valley Head, all collected by Mr. Smith in 1904, and sent for ex-

amination by Mr. Bryant Walker.

Pis. limatulum is related to P. punctatum Sterki, but considerably

larger, and like that minute Pisidium, ranges under the Rivulina

group. With a little care, it cannot be mistaken for any other

species; even half-grown examples are considerably different from P.

punctatum.

SENSITIVENESS OF CERTAIN SNAILS TO WEATHER CONDITIONS.

BY J. B. HENDERSON, JR.

While collecting last summer about Cazenovia, N. Y., my atten-

tion was constantly drawn to the extreme sensitiveness to atmos-

pheric conditions of several species of land snails. I was surprised

to find that upon some clear days collecting was excellent while

upon rainy days scarcely a living specimen could be found.

Puzzled by this failure of my expectations, I selected for special

observation a certain wooded hillside where the prevailing larger

types were Polygyra albolabris, thyroides, dentifera, Gastrodonta in-

tertexta, Omphalina inornata and fuliginosa. I visited the locality

from day to day keeping careful note of weather conditions.

I found that the periods of greatest activity among these snails

were invariably marked by a falling barometer, but these periods

began considerably before there were any noticeable meteorological

symptoms presaging rain. At the commencement of actual rainfall,

the larger Zonitids only remained especially active. Towards the

close of a rain period (generally lasting from twelve to twenty-four

hours) though before definite signs of clearing were apparent, all the

snails disappeared, sometimes almost completely. The bright clear

days succeeding a rain epoch were always poor collecting days, even

though the woods were left damp and wet from the drenching that

only a Cazenovia rain can give. It would appear therefore, that

the moisture in the air rather than that upon the ground influenced

110 THE NAUTILUS.

the snails. Their extreme sensitiveness was shown by their antici-

pation of a weather change from dry to wet, eight to twelve hours

before visible signs were given, but what seemed more remarkable

was the general withdrawal to shelter of all the snails during a rain

period two to three hours before a final clearing of the atmosphere.

A village neighbor kept alive all summer a fine large P. albolabris

in a small window garden. ‘‘Alby’s’’ mistress declared that he was

a most reliable barometer and that she could safely accept his weather

predictions. The mornings he selected for a stroll beyond the limits

of his garden were sure, she alleged, to be followed by thunder-

storms in the afternoon.

I also observed that upon certain fair days the board sidewalks

were covered with Cochlicopa lubrica, hundreds being crushed by

pedestrians. I was finally able to verify my theory that these tiny

mollusks left their damp retreats beneath the boards from six to

eight hours before rain. Indeed, I used the sign frequently to my

advantage to regulate my collecting rambles farther afield.

I was unable to discover that the small and minute species living

habitually under bark and among debris was affected by weather

changes, though I have little doubt that closer observation would

show them to be considerably influenced by the amount of moisture

in the air. The one very noticeable exception to this was in the

case of Strobilops. I learned to look for them only in the driving

rain, when they all left their usual stations beneath the bark of fallen

trees to crawl about in the open.

NOTE ON LUCINA (MILTHA) CHILDRENI GRAY AND ON A NEW SPECIES

FROM THE GULF OF CALIFORNIA.

BY WILLIAM HEALEY DALL.

In my synopsis of the Lucinacea (1901, p. 812) on the authority

of Dr. Carpenter (Suppl. Rep. Brit. Assoc. for 1863, pp. 552, 620),

I stated that the Phacotdes (Miltha) éhildrent Gray, was a native of

the Gulf of California and that the original ascription of it to Brazil

was an error. I am indebted to Dr. H. von Ihering of the Museu

Paulista, Sao Paulo, Brazil, for the means of correcting this state-

ment, which proves to be mistaken.

THE NAUTILUS. Li}

The shell was first described as Lucina childrene by Gray in the

Annals of Philosophy, for 1825, p. 136. Nearly at the same time

he referred to its unequal valves in the Zodlogical Journal, 1, p. 221.

In the autumn of the same year Sowerby figured the interior of a

right valve in part xxvii of his ‘* Genera”? under the name of

Lucina childrent. Only in 1828, in the supplement to Wood’s Index

-Testaceologicus, was the shell called Tellina childreni and figured on

supplementary plate 1, figure 1.

The shell was recently collected at Pernambuco by Senor Alfredo

dé Carvalho and sent to Dr. Von Ihering, who forwarded a speci-

men to the National Museum, thus confirming Gray’s original

locality. On comparison with specimens from Cape St. Lucas,

named by Carpenter, it became evident that we had to do with two

very similar but distinct species. ‘The rarity of the shell is doubt-.

less responsible for the delay in discovering the mistake.

The Brazilian species will of course keep the name given by

Gray. To the Cape St. Lucas form we may give the name of

. Phacoides (Miltha) xantusi in honor of its discoverer.

The differences are only apparent on a close scrutiny. The P.

xantust seems to be a smaller species when adult, more rounded,

more equivalved and with a shorter ligament. It bas a more or less

bifurcate and vermiculate radial sculpture, that of P. childreni

being finer, more regular and more distinctly divided into fine con-

tinuous radial grooves and a microscopic minor sculpture between

them.

As in many other Lucinacea, directly under the beaks there is a

small impressed area. In P. xantus? this in the right valve projects

so as to fill an excavation in the other valve and is so much impressed

as to make the beak appear sharper and more produced and to dis-

tinctly arcuate the two cardinal teeth. In P. childreni the area is

smaller, less impressed, not markedly extended toward the other

valve and the teeth remain straight. Outside this area a narrow

lunule, concentrically striated and bounded by an incised line, rises

almost vertically with a length of 19 mm. and a height of about 2

mm. In the Californian species the lunule is very small and bent

vertically downward so that in the closed valves it is excavated and

not projecting and has a length of about 6 mm. It is almost wholly

confined to the right valve. If my specimens fairly represent the

species, the posterior area in the Brazilian shell is proportionately

shorter than in the Californian and the basal margin much more pro-

duced.

It may be noted that all the figures, including that of Reeve in the

Ivonica (Lucina pl. iii, fig. 12, 1850), represent the Brazilian

species. ‘T’he group is represented by nine species in the Tertiary of

the Southern United States and Lower California, from the Clai-

bornian up to the Pliocene. It is interesting to find that the Florida

Pliocene, P. caloosana Dall, though smaller, has the upraised lunule

like that of Brazil; while the Pliocene, P. joannis Dall, of San Juan,

Lower California (opposite Guaymas), resembles the recent P.

xantust in having the folded lunule, only, in this case, the margin is

more deeply infolded and the shell heavier, more elongate-oval, and

about one-fourth smaller. It measures 55 mm. in height by 51 mm.

in width; P. xantust, 71 x 65 mm., and P. childreni. 86x 77 mm.

FURTHER NOTES ON THE SPECIES OF MARTESIA OF THE EASTERN

COAST OF THE UNITED STATES.

BY CHARLES W. JOHNSON.

Since the publication of my article on the species of Martesia of

the Eastern United States, I find I have overlooked two important

facts, involving one, and possibly two species. The first is Martesia

(Martesiella) fragilis Verrill and Bush (Proc. U. S. Nat. Mus.,

xx, p. 777, pl. 79, f. 10, 1898). For this species the above new

subgenus is proposed, ‘‘ which differs from Martesta in having a

well-defined, elongated, median, dorsal plate, posterior to the umbos,

in addition to the shield-shaped one over them.’”’ This seems to be

a typical Martesta for the ‘* elongated median, dorsal plate ’’ (meta-

plax) is present in all the species. ‘The description of the shell,

‘‘umbonal plate”’ (protoplax), and the figure would indicate that it is

very close to or identical with a small specimen of J. striata Linn.

The ‘* specimens were found in a piece of wood floating near Station

2565, N. lat. 37° 23’, W. long. 68° 8’,” about 500 miles off the

coast of North Carolina.

The second and more important omission was kindly pointed out

by Dr. Dall, who in a recent letter says: ‘‘ I read your paper in the

last NAUTILUS with much interest, but I cannot agree with you in

regard to the Pholas semicostata of Lea, for which I proposed the

THE NAUTILUS. 113

genus Scyphomya some years ago. It is entirely distinct from

Martesia and nearer Zirfaea in some of its characters, but very dis-

tinct from either. I have Carolinian specimens, but the shell ap-

pears to be rare.”

The genus Scyphomya was proposed in the Trans. Wagner Free

Inst. Science, vol. iii, pt. iv, p. 822, 1898, and while I consulted

this work I overlooked it from the fact that Dr. Dall places this

genus in the sub-family Teredinine, and I only went over that por-

tion pertaining to the genus Martesia. From the original descrip-

tion, and the figure alone one would feel doubtful in defining the

species. I therefore followed Tryon and left it in the synonymy

under &. striata.

NOTES ON SOME PREOCCUPIED NAMES OF MOLLUSKS.

BG AW ie: bts | AGI TE.

Prof. Cockerell has kindly called my attention to the fact that the

name Parmulina proposed by me Oct. 1, 1902, for a section of Circe,

had been used in the same year for a Rhizopod by Penard. Investi-

gation showing that the latter author had several months’ precedence

in publication, the name Parmulophora is proposed for the mollusk.

In the same work in which Parmulina was proposed, I note the

overworked name of Quadrula used for a Rhizopod. Rafinesque

precedes all others in the use of this name, which he applied to a

naiad, but it has been used for a Rhizopod, an insect and a crusta-

cean. .

I noticed while looking up the data in the case of Parmulina, that

the name Patinella, applied in 1870 by me to Patella magellanica and

its allies, had been previously used by Gray, in 1848, for a polyp.

In place of it for the limpet, I suggest Patinigera,

NAMES IN THE PUPILLIDE.

BY W. H. DALL.

In the January NauTiLus (page 105), Dr. Pilsbry discusses this

subject, and incidentally states that in my notes upon it in the Feb-

ruary number I corrected some errors, but complicated the question

“by a few new ones.” I beg to submit, with all deference to Dr.

Pilsbry, that it is not I who have introduced the new errors.

A more careful examination of Risso, Draparnaud and Pfeiffer,

would have shown him that Jaminia muscorum (Drap. not LZ.) Risso

is, as I stated, following Pfeiffer and other European authorities,

Pupa minutissima Hartmann, and not muscorum Linné.

It would be presumptuous in me to attempt for myself a synonymy

of the ancient species of common European land shells, which have

been worked over with the utmost care for a century by a long line

of distinguished students. I did not attempt it, but relied on such

respectable authorities as Gray, Draparnaud, and especially Pfeiffer,

than whom no one was more careful, erudite, and familiar with the

subject. In working out the details of the nomenclature of Pupillidx

(a work still in MS.), involving a great amount of labor, I have, as a

rule, adopted Pfeiffer’s conclusions as to specific identity as entitled

to greater weight than any others.

The result of a careful historical search through the whole applic-

able literature differs in important particulars from Dr. Pilsbry’s

table in the January number. It is, of course, true, that Pfeiffer,

like other people, is not infallible, nevertheless conclusions based on

his identifications deserve a certain amount of respect, and should

not be stigmatized as new errors, even if some doubt continue to ex-

ist in occasional instances.

Risso identified his species by Draparnaud’s posthumous mono-

graph and its figures, occasionally citing Ferussac and Playfair, and,

THE NAUTILUS. 115

under Jaminea, only once any older author. Hence the identifica-

tions of Draparnaud’s names and figures, which seem to be sufficiently

certain, settle definitely the place of Risso’s names. This results in

the following table for Jaminia :

Risso’s names. Pfeiffer’s identifications.

J. muscorum Drap. minutissima Hartmann.

marginata Drap. muscorum Linné.

edentula Drap. edentula Drap.

secale Drap. secale Drap.

tridens (LL. Gmel.) Drap. tridens Miiller.

granum Drap. granum Drap.

sulculata Risso. unidentified.

trilamellata Risso. ef

heterostropha Risso. quadridens Muller.

quinquelamellata Risso. quinquedentata Born.

septemdentata Risso. avenacea Brug.

heptodonta Risso. unidentified.

multidentata Risso. polyodon Drap.

niso Risso. niso Risso (doubtful).

Pfeiffer (Nomenclator, p. 356, No. 108) identifies J. edentula Risso

positively with Pupa edentula of authors, but under obscurus also

enters the name with a query, probably by some transposition of in-—

dex slips, since the figure cited by Risso cannot represent obscurus,

which is elsewhere well figured by Draparnaud. This results in the -

inclusion of Sphyradium and the exclusion of the Ena of Dr. Pils-

bry’s table.

Alza of Jeffreys was proposed for dextral Pupillide, but as this

distinction is practically valueless, we have to fall back on his list of

species and proceed by elimination to get the group which will bear

the name permanently.

The table of equivalents for his original list is as follows in their

original order :

Jeffreys’ names (1830). Pfeiffer’s identifications.

1. Pupa marginata Drap. = muscorum L. not Drap.

2. .~ nitida Jeffreys. = edentulum Drap.

3. °* ~revoluta Jeffreys. = edentulum var.

4, ‘ eylindrica Jeffreys. = minutissima Hartmann.

d. ‘ vulgaris Jeffreys. = pygmea Drap.

6. ‘ palustris (Leach MS.)

Jeffreys, = antivertigo Drap.

116 THE NAUTILUS.

Of these 1 = Pupilla, 1831; 2 and 3 = Sphyradium, 1837; 5

and 6 = Vertigo Muller, 1774; leaving only 4, minutissima, which

becomes the type. All the eliminations antedate Gray in 1847,

who named palustris (= antivertigo) as type too late. Herrmannsen

says that muscorum and antivertigo are the types, and that Beck re-

stricted it to antivertigo. The latter statement is an error, as Beck

did not restrict the group at all, or‘name any type, giving a hetero-

geneous list much like that of Jeffreys.

The correction of hordacea ‘‘ Gabb” to hordeacea “ Sterki, not

Gabb,” may be allowed in view of the data given by Dr. Pilsbry,

but, in a general way, when a species, not of the writer’s own, is

mentioned by an author without further data as type of a new group,

it is, I think, essential not to ‘‘ go behind the returns,” as any other

way must lead to hopeless confusion.

My notes in the article referred to, were condensed from some

hundred pages of synonymic data, and no attempt was made to give

more than the barest outline of the cases cited. But in every case

good reasons can be adduced for the position taken, though no one is

less ready to claim infallibility than the present author.

THE PUPILLIDZ OF RISSO AND JEFFREYS.

BY HENRY A. PILSBRY.

The first attempt at a difficult and involved problem often falls

short of a complete solution, through the omission of some obscure or

apparently irrelevant factor bearing upon the matter; but the work

done clears the way for another student to approach the task more

advantageously. A discussion like the present one upon the Pupz

is not properly to be called a controversy. It is a symposium, to

which various students bring their several portions of fact, observa-

tion and deduction, to the end that harmonious structure may be

built more symmetrical than any formed by a single effort.

My former paper upon Pupillide (NAvuTILUS, January, p. 105),

was faulty in two respects: first, in ascribing ‘ new errors”’ to Dr.

Dall, for I propose to show that the errors largely antedate his work,

and second, in my failure to give at length my reasons for certain

identifications of some of Risso’s names. These reasons I will pro-

THE NAUTILUS. L117

ceed to give, so far as they relate to species about which there is any

difference of opinion.

Dr. Dall’s identifications of Risso’s list of species of Jaminia agree

with those given by me except for the following four species:

Risso’s name. Dall’s table (p. 115). —_—- Pilsbry’s table (p. 105).

(1) J. muscorum. minutissima Hartm. PP. muscorum L.

(2) J. marginata. muscorum L. P. umbilicata Dr.

(3) J. edentula. edentula Drap. B. obscurus Mull.

(4) J. quinguelamellata. quinquedentata Born. P. cinerea.

My reasons for the names given in the third column follow:

(1). J. muscorum. ‘The identity of this shell is at first sight not

very clear. Risso refers to Drap., who (very badly), figures P.

minutissima under the name muscorum; but Risso’s description does

not at all fit mznuwtissioma, nor does the size given. Bourguignat, who

examined the Risso specimens, refers them positively to the P. mus.

corum of L., as understood at the present time, and the description

agrees with this species. Risso’s specimens would fall in the form

‘* unidentata,”’ Risso describing it as with a very small posterior la-

mella.

The evidence obtained by a careful study of the original work

therefore shows that Risso did not have P. minutissima.

(2) J. marginata. Risso gives three references: ‘‘ Drap. 61, 6,

iii, 36, 38. Feruss. 59, 475. Playf. 59, 9, iii, 23, 24,” all of them

pertaining to forms of muscorum L. ‘‘ Playf.” is not Playfair, as

might be supposed, but Risso’s curious conception of the name

Pfeiffer ; the work referred to being Carl Pfeiffer’s Systematische

Anordnung und Beschreibung deutscher Land und Wasser-Schnecken

(1821). Pfeiffer is elsewhere referred to as ‘ Pleyfel !”

Risso says that the peritreme is provided with a long acute lamella

posteriorly on the right. This cannot be made to fit any form of

muscorum, but applies pertectly to wmbilicata Drap.; and Bourguig-

nat referred Risso’s specimens, which he examined, to that species.

(3) J. edentula. This is described by Risso as with edght whorls,

toothless aperture, and fen mm. long, so it clearly is not Sphyradium

edentulum, as Dall supposes. It is obvious that the reference to

Draparnaud’s P. edentula was an error. These and the other char-

acters given by Risso agree with Buliminus obscurus (Ena obscura),

118 THE NAUTILUS.

which occurs at Nice; and Bourguignat, who examined Risso’s col-

lection, has recorded this identification.

(4) The last of the four cases is only a nominal disagreement, the

two names referring to one and the same species. I used that of

cinerea Drap. because grave doubt has been cast upon the identity of

Born’s quinquedentata with the form so named by many later authors,

> is a common name for the form in collections.

while ‘* Pupa cinerea’

This disposes of all the cases in question, and so far as I can see,

the name /aminia will be retained for Risso’s second species J. mar-

ginata Risso = Pupa umbilicata Drap. It will be noted that Dall,

in his first article, also selects Risso’s second species as type, but as

he was misled by a wrong identification of marginata Risso, he did

not use the name for the same group. Jaminia isa genus of the

‘¢ Kuropean system ”

with no species in America. It has a great

superficial resemblance to Pupzlla, but with some extraordinary

characters certainly entitling it to generic rank.

I am not concerned to show whether or not Pfeiffer correctly

identified Draparnaud’s figures, but I fully share Dr. Dall’s confi-

dence in his general accuracy. While there is no doubt that Risso,

like everybody else at that time, identified his shells largely by Drap-

arnaud’s volume, yet his names do not rest for identification solely

upon the references to Draparnaud any more than Binney’s species

rest upon the references he cites. Primarily, they rest upon the de-

scriptions given by Risso himself. ‘To identify Risso’s species by the

references to Draparnaud’s figures presumes absolute accuracy of

identification on Risso’s part. Therefore, in discrediting the identifi-

cations as given by Dr. Dall, I am not questioning Pfeiffer’s relia-

bility in the least. I am simply recording a few of the mistaken

identifications of Risso, who, it is acknowledged by all who have used

his work, was careless to a degree.

Dr. Dall, in using Risso’s list, considers it necessary to point out

what his snecies really are in terms of Pfeifferian nomenclature.

But it seems to me that the very foundation of the subsequent struc-

ture is involved in getting at the actual identity of the species in

question. Otherwise conclusions based upon the list are without

permanence. The names can either be taken as they stand in Risso,

or they can be really corrected. No half-way correction of the list

of species goes to the root of the matter. There probably cannot be

found a zoologist of experience in the world who will support the

THE NAUTILUS. 119

method of identifying Risso’s species by means of Pfeiffer’s identifi-

cations of Draparnaud’s figures, as opposed to the method by the

study of Risso’s own descriptions.

In my opinion, any sound work based upon Risso must begin with

a study of his descriptions, specimens in hand. In the case of non-

marine forms, the task has been materially lightened by Bourguignat,

who examined and reported upon Risso’s collection; but even with

this, it is safest to check up all points with the shells and descriptions

themselves.

In the matter of Alxa Jeffreys, a few words may not be amiss. I

hold that when an author distinctly indicates a certain group by his

diagnosis, the mere inclusion of some heterogeneous species should not

be allowed to totally pervert his intention. This is common law,

and good law too. Now Jeffreys defines Alza as having short

lamellz in the mouth (making no provision for toothless forms in

his diagnosis); and he expressly states that Alza is separated from

Vertigo because the shell is dextral (the type of Vertigo being sinis-

tral).

Now there are still authors who hold that the dextral Vertigines

need a subgeneric or sectional name, and from the time of Gray

(1847) to the last Catalog of Westerlund (1890) the name Alza,

with the type antivertigo has been more or less constantly in use. I

do not think that Dr. Dall can brush aside these facts by stigmatiz-

ing the distinction for which the name has always stood as ‘‘ practi-

cally valueless,” and proceed to fasten a totally new significance

upon it. Quite a respectable company of conchologists of high rank,

including Pfeiffer (in the Nomenclator Hel. Viv.), find use for Alzxa

in the sense established by Gray, as set forth in my former note.

I do not wish to be understood to break a lance in support of the value

of Alza asa division of Vertigo; butadivision adopted by Pfeiffer and

other high authorities is at least entitled to respectful consideration.

It seems inadvisable to use the name of such division for a totally

different group, at all events until malacologists recognize a Supreme

Authority who shall pronounce once for all upon what distinctions

are ‘practically valueless,’’—a consummation remote from this con-

tentious generation.

The facts are, in short, as follows: (1) Jeffreys regarded the

toothed forms of his list as typical of his group. Gray in 1847

selected one of these, P. antivertigo, as type, that species never be-

120 THE NAUTILUS.

fore having been selected as a genotype. (2) This usage has ob-

tained currency by numerous authors, while the name has never been

used in any other sense. (8) Dall (1904) ignores this use of the

name, and selects a new type which disagrees wholly with the origi-

nal diagnosis, though included by Jeffreys in the original list of

species, |

The cases of Jaminia and Alga are now respectfully submitted for

the judgment of conchological and nomenclatorial experts.

NOTES AND NEWS.

We regret to announce the death of Rev. E. H. Ashmun, which

occurred at San Rafael, California, Dec. 21,1904. We hope to give

a further notice next month.

Mr. FrepERICcK Price Marrart died at Liverpool, England, on

November 7, 1904, at the age of 84.‘ For more than 40 years Mr.

Marrat had been connected with the Liverpool Museum, where he

worked in conjunction with the late Mr. T. J. Moore and the Rev.

H. H. Higgins, a trio of enthusiastic museum workers who con-

tributed so greatly to the building up of the magnificent collection in

the Liverpool Museum. Mr. Marrat paid special attention to the

geological, mineralogical and conchological collections, his most in-

timate work being connected with conchology, not only the concho-

logical collection in the Liverpool museum being named by him, but

also similar collections in various museums, and also in private

houses. He was the principal authority on the genus Oliva, of which

he acquired a very extensive series, and contributed monographs to

Reeve’s Conchologica Iconica and to Sowerby’s Thesaurus Conchy-

liorum, as well as to many periodicals and other publications on the

mollusca.”—(Museums Journal, Dec., 1904.)

EDWARD H. ASHMUN.

THE NAUTILUS.

Vor. < VILI. MARCH, 1905. ING: LT

EDWARD H. ASHMUN.

Rev. Edward Houghton Ashmun, was born at Tallmadge, Sum-

mit Co., Ohio, March 12, 1853. Most of his boyhood was spent

there, his father being a farmer. When seventeen he moved

with his father to Weeping Water, Nebraska. As time went on, he

became strongly impressed with a desire to enter the ministry, and

toward that end went to Tabor College, at Tabor, lowa, where he

graduated in 1879, and entered the Yale Divinity School, finishing

in 1882. He was pastor ot the Congregational Church at Syracuse,

and Beatrice, Nebraska, after which he was called to the Boulevard

Church in Denver, Colorado, which became very prosperous under

his ministry. In 1892 he was appointed to the position of Home

Missionary Superintendent of Arizona and New Mexico, in which

position he remained six years, and then Pastor Superintendent of

Arizona for two years, residing at Jerome, Arizona.

It was during his residence in the southwest that Mr. Ashmun

became interested in studying the land shells of that region, and

made many rare and interesting discoveries. Collecting in this arid

region is laborious and rarely as remunerative as in the more fertile

sections. ‘The molluscan fauna is largely confined to the higher

mountains, the only situation where there is sufficient moisture for

snail life; species are thus widely separated and insulated by the

lower and arid wastes, thus presenting as many interesting problems

in distribution as exist in true insular faune. Under the above

conditions lives a group of snails, with shells like those of Polygyra,

but anatomically very distinct, and nearer related to Sonorella,

12> THE NAUTILUS.

which on the other hand is related to Epiphragmophora. To this

group of shells Messrs. Pilsbry and Cockerell, gave the name of

Ashmunella* in recognition of his valuable field work. Mr. Ashmun

also discovered a number of new Pupide, etc. as shown by the follow-

ing list. of new species collected by him in that region :—

Bifidaria perversa Sterki. Ashmunella rhyssa Dall.

Bifidaria quadridentata Sterki. | Ashmunella miorhyssa Dall.

Bifidaria ashmuni Sterki. Ashmunella ashmuni Dall.

Pupilla sonorana Sterki. nensis A. & C.

Pupilla sonorana tenella Sterki. Agriolimax ashmuni Pils. &Van.

Pyramidula cockerelli: Pils. Sonorella ashmunt Bartsch.

Mr. Ashmun’s article on ‘Collecting in Arizona and New

Mexico” (Tur NavtiLus, xiii, p- 13, 1899) is very interesting and

gives a good idea of the difficulties which attend collecting in that

region. Conjointly with Prof. Cockerell he described a new sub-

species of Ashmunella (A. pseudodonta capitanensis}. It was collected

on the Capitan Mts., New Mexico, at an elevation of 8, 200 feet.

(Navy. xit,-p. 13), 1399):

During his last year in Arizona his health beeen to fail, and he

moved to Idaho, hoping that the change would benefit him, but after

two years as pastor of the church at Weiser, he had to give up his

charge, and after a time was obliged to go to a sanitarium, where he

remained ten weeks and was apparently cured of the stomach trouble

with which he had been suffering. He was advised to live out of

doors as much as possible for two years, and was appointed to inves-

tigate the mosquito pest at San Rafael, California. This seemed to

furnish the outdoor life he needed, and he improved for a time, but

in the fall caught a cold and finally had to give up. He was

threatened with paralysis from the first, and it seemed that his nerve

exhaustion was complete. He again went toa sanitarium, but nothing

could be done. He died December 21, 1904, and was interred at

Santa Rosa, California.

He was married in 1890 to Miss Anna L. Lyman, daughter of the

Rev. Addison Lyman of Kellogg, Iowa, who with a son, Henry G.

Ashmun, a bright boy of twelve, survives him, and to whom we ten-

der our sincere sympathy. C.., Wit.

SOME NEW SPECIES OF MOLLUSKS FROM CALIFORNIA.

BY WILLIAM HEALEY DALL.

In assorting some mixed material from California a number of

new species were noted; and, as it has become necessary to refer to

some of them by name, the following preliminary diagnoses are given.

Leda amblia n. sp.

U. S. Fish Commission station 4517, Monterey Bay. Shell

chalky under a polished dark olive-green periostracum, compressed,

rostrate, concentrically and feebly irregularly striate, with obscure

microscopic radial lines; lunule narrow, lanceolate; escutcheon, long,

wide smooth and slightly concave, the valve margins rising slightly

in the median line; valves bluntly rounded in front, bluntly truncate

behind, the rostrate portion not set off from the body by any con-

striction, and the radial subangular lines which bound the rostral area

are feeble and obscure; interior whitish, with a deep subumbonal

impression, a very shallow and obscure pallial sinus, very short

siphons, 12 or 13 anterior, 18 or 19 posterior normal hinge teeth,

with a narrow, backwardly oblique socket for the resilium. Lon. of

adult shell 18.0 ;-alt. 9.5; diam. 5.5; vertical of the beaks behind

anterior end, 7.0 mm. This has much the general form of L. leonis,

Dall, but wants the prominent sculpture and is of a different color.

Magilia perattenuata n. sp.

Monterey Bay, 10-45 fms., Woodworth. Shell small, very

slender, with one smooth turgid nuclear, and six smooth normal

whorls; the whorls are but slightly convex, whitish, the suture very

distinct, its posterior margin slightly overhanging or dominant; aper- |

ture narrow, short, simple, the outer lip slightly concavely waved

between the periphery and the suture, canal short, a little recurved,

relatively rather wide. Lon. of shell 9.5; of last whorl 3.75; max.

diam, 2.5mm. A single specimen sent by Mr. Woodworth is broken

and dead, but its characters are not shared by any other species from

the Coast as far as now known.

Admete woodworthi n. sp.

Monterey Bay, 10-45 fms., Woodworth. Shell small, thin, whitish,

with a yellow-brown periostracum, five normal, sculptured, and one

124 THE NAUTII.US.

smooth, turgid nuclear whorl, gradually increasing, subtalulate by a

prominent spiral thread at the shoulder while young, rounded at the

last whorl, with 8 or 9 obscure riblets on the upper part of the spire,

which are obsolete on the last whorl and a_ half; spiral sculpture of

rounded threads, with wider flattish, somewhat irregular interspaces;

peristome continuous with a slight notch or sulcus near the end of

the nearly straight pillar, and with no umbilicus; there are two ob-

scure plaits on the pillar, which is not marked by any umbilical chink

or fissure; aperture with the external sculpture modifying the margin.

but no lirations. Lon. of shell 9.0; of aperture 4.0; max. diam 4.5

mm.

This is less strongly sculptured, more slender and with a less ar-

cuate pillar than any of the other Admetes of the coast. and belongs

in the group half way between such Cancellarias as C. modesta and

Admete gracilior Carpenter. It has very much the form of C. etr-

cumcarinata Dall, on a smaller scale and with a more acute spire.

Erato albescens n. sp.

U.S. Fish commission station 4431, California. Shell whitish, thin

‘and polished, with four whorls; the spire low and nearly covered

with a thin glaze extending from near the aperture; shell bluntly

pyriform with a wide mouth, smooth pillar, the outer lip thickened,

obscurely marginate externally, with about nine obscure distant den-

ticulations internally, pillar short, twisted, with a flaring edge and

almost gyrate axis; the body with a thin wash of callus, but, in the

type no sign of pustulation. _ Lon. of shell 15.0; of aperture 13.5;

max. diam. 10.0 mm.

This succeeds #. vitellina Hinds as the largest species of the genus

and is a much thinner and lighter shell, beside differing in color.

Sctssurella (Schizotrochus) kelseyi n. sp.

California at U. S. Fish Com. Station 4353, also off San Diego.

Shell large for the genus, trochiform, white, with about four

rounded whorls, sculptured with fine (forwardly convex) arcuate

threads or raised lines, which above the fasciole are spirally micro-

scopically striate, and on the base, with somewhat regularly spaced

and stronger spirals; the fasciole is narrow, slightly above the

periphery, bounded by two sharp, very thin, elevated keels; the slit

TUE NAUTILUS. a

extends about one-fifth of the circumference of the last whorl, The

aperture is nearly circular, interrupted for a short distance by the

body, the inner lip slightly reflected over a small umbilicus; the

operculum is multispiral and pale yellow. Alt. of shell 6.0; of

aperture, 3.0; max. diam., 5.5 mm.

This species is somewhat like S. umbilicata Jeffreys from the

North Atlantic, but is larger, more strongly sculptured and more

elevated proportionately. It is the second species of the family to

be described from the Pacific Coast; the other Sehismope rimuloides

Carpenter having been reported from San Diego and Mazatlan. It

is named in honor of Prof. F. W. Kelsey, of San Diego, to whose

interest in the local mollusks we owe several additions to that fauna.

CRITICAL NOTES ON THE SMALLER LYMNAEAS.

FRANK COLLINS BAKER.

‘The small forms of Lymnza, which have been included under the

names of humilis and desidiosa, have been little understood by Amer-

ican conchologists, at least two good species being included in

humilis. A recent somewhat exhaustive study of these small forms

has led the writer to conclusions diametrically opposed to those held

by Binney and Tryon and most subsequent students of fresh-water

mollusks.

In pursuing these studies, the types of Say’s and Lea’s species in

Philadelphia and Washington have been examined, and in addition

the collections of the Philadelphia Academy of Natural Sciences,

the Smithsonian Institution, Mr, Bryant Walker, Detroit, Michigan,

Mr. Henry Hemphill, San Diego, California, Mr. J. H. Ferriss,

Joliet, Illinois, and the Chicago Academy of Sciences have been

studied. My thanks are due to the above-named gentlemen for the

use of their collections, and also to Dr. W. H. Dall, Dr. H. A.

Pilsbry, Mr. Paul Bartsch and Mr. E. G. Vanatta, for much valu-

able assistance and kind criticism.

Lymnea humilis Say.

Lymnexus humilis Say, Journ. Phil. Acad., II, p. 378, 1822.

Lymnea griffithiana Lea, Proc. Amer. Phil. Soc., I], p. 33, 1841.

126 THE NAUTILUS.

Lymnea linsleyi DeKay, N. Y. Moll., p. 72, pl. iv, fig. 74, 1848.

Lymnea lecontii Lea, Proc. Phil. Acad., p. 112, 1864.

In this species American conchologists have confused several

seemingly valid species. Say’s types (two specimens) preserved in

the Philadelphia Academy, came from South Carolina and agree

fairly well with Binney’s figure 99, in Land and Fresh-Water Shells

of North America. The South Carolina specimens are a trifle nar-

rower and less rotund than specimens from the north. Humilis is of

good size, with regularly rounded whorls, a broadly conical spire,

impressed sutures, 5-55 whorls, aperture elongate-ovate and a trifle

less in length than the spire. ‘The last whorl is somewhat inflated,

and the umbilical chink very distinct, being more open in some

specimens than in others. ‘The surface is marked by lines of growth,

and in some specimens from Maine by elevated spiral ridges. The

fine impressed sculpture of some Lymneas (as columella) is absent

in this species, as well as in the others mentioned below. Typical

measurements are as follows :

Length 9.00; width 4.75 ; aperture length 4.50 ; width 2.75 mill.

(Say’s type.) |

Length 8.50; width 4.00 ; aperture length 4.50 ; width 2.75 mill.

(Chicago. )

Length 7.50; width 4.25 ; aperture length 3.50 ; width 2.50 mill.

(Maine. )

Small forms of Lymnea. cubensis Pfeiffer, resemble humilis ;

cubensis has a wider, more solid shell, a more open umbilicus, and

the expansion of the columella is broader and of a different form, as

is also the aperture. | |

L. humilis is found from Maine to California, and from Canada

to Mexico.

Lymnea parva Lea.

Lymnea parva Lea, Proc. Amer. Phil. Soc., II, p. 88, 1841.

Lymnea curta Lea, Proc. Amer. Phil. Soc., II, p. 338, 1841.

This is a very small species, in fact the smallest of the Lymneas.

It differs from humil’s in its diminutive size, and in the very differ-

ent form of the shell, which is solid, translucent, turreted ; color

light brown or yellowish-white ; whorls 44-5; these are more con-

vex than in humilis, caused by the more deeply impressed sutures ; -

the spire forms an acute vyramid in some specimens, and a broad

pyramid in others, and is considerably longer than the aperture ; the

aperture is roundly elliptical and almost continuous, differing mark-

edly in this respect from humilis ; the inner lip is more erect in the

present species, which causes the umbilicus to be round, deep and’

open. The umbilical region is gracefully rounded. Typical ex-

amples measure as follows :

Length 6.00; width 3.00; aperture length 3.00; width 1.75 mill.

(Indiana. )

Length 6.00; width 3.00; aperture length 2.50; width 1.25 mill.

(Penn.)

Length 5.50; width 3.00; aperture length 2.75; width 1.50 mill.

(Ills.)

This species is widely distributed, being found from Maine to Cali-

fornia and from Canada to Mexico.

Lymnea desidiosa Say var. modicella Say. -

Lymeus modicellus Say, Jour. Phil. Acad., V, p. 122, 1825.

Say described this species from two specimens which are still pre-

served in the Philadelphia Academy. It would seem to be distinct

enough to be recognized at least as a variety of desidiosa, to which

it is more closely allied than to humilis. The principle characteris-

tics are the short, dome-shaped spire, the regular elongate-ovate aper-

ture and the large size of the last whorl as compared with the spire.

The umbilical chink is narrowly open and there is a small plait on

the columella. Typical specimens measure as follows:

Length 8.50; width 4.75; aperture length 4.75; width 2.75 mill.

(Say’s type.)

Length 7.75; width 3.25; aperture length 4.50;. width 2.25 mill.

(Berry Lake.)

Length 7.00; width 3.50; aperture length 4.50; width 2.00 mill.

(Berry Lake.)

The range of this form, as far as known, is from Ontario to Oregon

and south to Texas. It has been found in Big Payette Lake, Idaho,

at an altitude of 5,000 feet above the sea level.

The forms described by Dr. Lea as L. plica, planulata, ex’gua and

rustica seem to be absolute synonyms of desidiosa, some of these

being, in all probability, immature forms. The types of exigua and

rustica are not in existence, so far as known. They are not in the

Phiiadelphia Academy nor in the Smithsonian Institution.

A NEW SPECIES OF PISIDIUM.

BY V. STERKI.

Pis. atlunticum, n. sp.

Mussel of medium size, somewhat inequipartite, oblique, short, an-

gular, rather well inflated ; superior margin, moderately to rather

strongly curved, with the angles at the scutum and scutellum pro-

jecting and more or less rounded ; supero-anterior slope well marked,

steep, slightly curved to almost straight, anterior end a rounded

angle situated low; posterior part high, posterior margin (squarely )

truncate to subtruncate to rounded, inferior well curved; beaks some--

what nearer the posterior end, rounded, prominent over the hinge

margin, rather variable; surface dull to somewhat shining, with

strie very fine and crowded over the beaks and somewhat coarser

towards the margins; color straw or whitish to pale horn to grayish

or brownish ; shell opaque to more or less translucent, rather thin,

nacre glassy to whitish ; inner surface densely rugulose within the

pallial line, muscle insertions distinct; hinge rather slight, curved,

plate narrow ; cardinal teeth: the right curved to angular, its pos-

terior part thicker and grooved, the left anterior short, angular, the

posterior oblique, short, slightly curved, thin, less projecting than the

anterior; lateral teeth rather slight, the inner cusps of the right

valve not pointed, the outer quite small, those of the left valve

pointed, not very abrupt; ligament slight.

Size: long. 4.3, alt. 3.8, diam. 2.6 mill.

to size, shape, relative size and prominence of the beaks, strie and

appearance of the surface, color, translucency or opacity of the

shell. Some of the full-grown examples are straw-colored all over,

others horn or grayish with a broad or narrow light zone along the

margins. None of the different forms can be regarded and described

as typical and the others as varietal since they are connected by in-

tergradations. In younger specimens, the superior margin is gener-

ally less curved, the anterior and posterior more so than in the adult.

The rugosity of the inner surface of the shell is like that of Pis. nov-

eboracense, although microscopical, much coarser than e. g. in P.

variabile Pr. and compressum Pr.

Pis. atlanticum seems nearest related to P. noveboracense, but the

mussel is shorter, its posterior part comparatively higher, the supero-

anterior slope is steeper and the color is different.

SOME NOTES ON BERMUDIAN MOLLUSKS.

BY OWEN BRYANT.

Dr. Pilsbry, in his article on “ The Air-breathing Mollusks of the

Bermudas ”’ in Transactions of the Connecticut Academy (Vol. X,

part 2, p. 493, Sept., 1900) says: *“‘ From the data supplied by Prof.

Verrill’s expedition and that of Prof. Heilprin, it seems that Val-

lonia pulchella, Oecilioides acicula, Agriolimax levis and Physa acuta

rest upon single records now nearly twenty years old, and they may

not have permanently colonized ; but as none of them are conspicu-

ous forms, and no special collectors of land shells have sought for

them, the merely negative evidence is inconclusive.’’.

In this connection it is interesting to note that Physa acuta Drap.,

was found by Mr. Davis and recorded in the Navrirus (Vol.

XVII, p. 125, Mar., 1904). Cecilioides acicula Mill. and Val-

lania pulchella Mill. were found by Mr. Addison Gulick and myself

on the grounds of the Hotel Frascati, while studying at the Ber-

muda Biological Station in July and August, 1903. <A careful

search would very likely reveal Agriolimax levis Mull.

muda, by J. M. Jones. Halifax, 1876, p. 1388). It occurs also in

the lists of Bland, 1881 (In Wallace’s Island Life, p. 256) and of

Heilprin, 1889 (The Bermuda Islands, p. 182).

I found it scarce under loose stones on the grass near the FarabpAg.

Cecilioides acicula Mill.

First recorded by Bland in 1861 (Annals of the Lyceum of

Natural History of N. Y., VII, p. eno! Also recorded by Jones in

1876.

I first found a dead shell of this species in looking over some red

earth at the laboratory. Later I discovered thirty-five or more on

the ground under an overhanging stone about 100 feet from the first

locality. Most of these were either alive or recently dead. The,

soft parts were drawn up above the body whorl. It probably lives

in the grass. | |

For the identification of this species I am indebted to Mr. Paul

Bartch who kindly compared specimens with those in the National

Museum.

Zonitoides arboreus (Say ).

This species is apparently unrecorded; a considerable number were

on the under side and in the crevices of a large rotten log in a

bamboo thicket.near the Frascati. They are somewhat lighter and

yellower than New England specimens.

Vitrea lucida (Drap.)

The first mention of this species is made by Prof, A. E. Verrill

(Trans. Conn. Acad. Vol. xi, pt, 2. p. 738, fig. 81), who says: The

fresh shells of this species were found in large numbers by Mr. A. H.

Verrill in March 1901,in a garden at Hamilton but none were living.

The Jast whorl of many of the shells was distorted and rough, as if

the conditions had been unfavorable for some time before death.

Perhaps the weather was too dry. It is doubtful therefore whether

it has succeeded in establishing itself permanently in theislands. It

is a native of southern Europe.”

I found this species very abundant in the Botanical Garden, at

Hamilton. They were on the ground and under leaves in flower

beds, and beside a wall where shrubs and vines were growing. Many

were alive though a large proportiun showed the distortion which

Professor Verrill speaks of and which is well shown in the figure he

gives.

TIE NAUTILUS. 131

Vitrea lucida seems now to have become a part of the fauna of the

Bermudas.

In closing I take pleasure in acknowledging my indebtedness to

Mr. A. Gulick for his kind assistance in the determination of the

species named above, and to Dr. Pilsbry for the final determination

ot Vitrea lucida and Zonitoides arboreus.

NOTES.

PENNSYLVANIAN SNAILS AND THE STATE ZOOLOGIST.—In the

last Monthly Bulletin of the Division of Zoology of the Pennsyl-

vania State Department of Agriculture (Vol. II, no. 8), Prof. H. A.

Surface, the State Economic Zodlogist, remarks (p. 245): ‘* Since

very little has been written concerning the molluscan life in Penn-

sylvania, we may at some future time prepare a Bulletin upon this

particular subject,” ete., etc. As most of the common non-inarine

mollusks of the Eastern States were described by Thomas Say from

Pennsylvanian examples, and there have been articles bearing on

our mollusks published at pretty short intervals for almost a century,

we had somehow gotten the idea that a good deal had been “ written

concerning molluscan life in Pennsylvania.”’ To be told that all that

conchologists have done upon Pennsylvanian‘ mollusks in a hundred

in the official eye of the State Zoologist,

_ years looks * very little’

is discouraging. He must be looking for something the size of the

LIST OF SHELLS FROM NORTHWESTERN FLORIDA.

BY BRYANT WALKER.

In the fall of 1902, Messrs. G. F. & B. H. King of Mimsville,

Ga., to whom we are indebted for the discovery of several new spe-

cies of Unionide recently described in the Nautilus, took a wagon

trip of more than one hundred miles from their home into western

Florida. No land shells were collected. The list of fluviatile spe-

cies, however, though not large, is of considerable interest, especially

as there are practically no records from that part of the state. En-

tering Florida at Neal’s Landing, the Chipola River was struck at

Marianna. From there the route continued southwesterly to

Econfina on Econfine Creek. No Unionide were found in the

Econfine, but in a tributary called Moccasin Creek, several species

occurred, The Chipola River isa branch of the Flint River. Econ-

fine Creek flows directly into St. Andrew’s Bay.

This fine species, the largest yet known of the genus, was found in

some abundance in the Chipola River. Only a few occurred at the

other localities.

It differs from all the described forms in its size and peculiarcom- .

bination of characters. Young specimens of about five whorls,

except in being imperforate, slightly wider and more strongly

transversly_ striate, closely resemble striate specimens of LZ. sub-

carinata in shape, the shouldering and carination of the whorls

being almost exactly the same. But with increase of growth the

shape becomes entirely different and the mature shell in general ap-

pearance approaches Lea’s L. edliottci, but differs from that species in

being very much larger, proportionately wider, with the lower whorl

more flatly shouldered, with transverse raised lines and imperforate

axis.

I take great pleasure in naming it after Dr. Pilsbry.

This species is apparently one of the characteristic forms of the

Flint river drainage system. Originally described from Vienna in

Dooley County, Ga., the Messrs. King have found it in great abund-

ance in Rawle’s Spring and Dry Creek, Early County, and in the

Chickasawahatchee Creek, Baker County. From Mr. A. C.

Billups, I have also received it from the Flint River. On the

present trip it was found in both the Chipola and Econfine.

The color both of the epidermis and nacre is also quite different.

Messrs. Frierson and Marsh, to whom specimens have keen sub-

mitted, agree that it is distinct from any described fo:m, and Mr.

Simpson remarks that it ‘ looks more or less like two or three species,

but I cannot refer it to anything.”? Mr, B. H. Wright suggests that

it is close to some forms of UW. confertus Lea, but both in shape and

color, which is remarkably constant in all the specimens seen, it

seems sufficiently distinct.

the tip being nearly on the median line of the shell; posterior ridge

somewhat angled; dorsal slope covered with strong sub-concentric,

somewhat irregular ridges extending from the posterior ridge to the

margin; basal margin regularly curved; hinge margin nearly

straight, slightly angled between the cardinal and lateral teeth.

Cardinal teeth crenulate, erect, rather compressed, those in left valve

nearly on the same line; latera] teeth slender, straight and nearly

smooth. Anterior cicatrices well impressed, posterior cicatrices

distinct, dorsal cicatrices under the plate behind the cardinal teeth.

Beak cavity rather shallow, cavity of the shell deep and uniform.

Nacre bluish-white, rather thicker anteriorly.

Length 36; height 19, width 13 mm.

Habitat, Calvary, Ga.

Only three specimens of this little species were received, and these,

unfortunately, without any information as to the stream where they

were found. |

This species belongs to the ‘‘ conradicus”’ group of Medionidus as

defined by Simpson, and is most nearly related to MW. penicillatus.

But it differs decidedly from all the described species in the com-

pression of the anterior end, the elevation of the superior-anterior

margin and the regularly rounded posterior margin, which is equally

curved above and below, the tip being nearly on the median line and

not depressed toward the basal margin as in all the allied species.

The ridges on the posterior slope are quite as strong, but not so

numerous as in UW, kingii.

It is named in honor of Mr. Charles 'T. Simpson, whose recent

retirement from active conchological work has been a source of regret

to all interested in American Conchology.

A NEW LOCALITY FOR CERION INCANUM.

BY CHARLES T. SIMPSON.

I have just returned from a visit to ‘‘ Baker’s Haulover,” the nar-

row strip of land between the extreme upper end of Biscayne Bay,

Florida, and the Atlantic. This strip may be twenty rods wide, is

low and covered with mangroves on the inner side, and next the

ocean is sand-bank twelve or fifteen feet high with shore grapes, low

shrubs, grass and weeds. On the sandy part I found immense num-

bers of dead shells of Cerion incanum and a diligent search revealed

a few living examples on grass close to or even on the sand. As the

weather for the past few days had been unusually cold, I thought it

possible that it might be buried in the sand, and digging around the

roots of bunches of grass I unearthed the spevies alive by thousands.

In some cases a double handful would be buried around a small

bunch of grass. Many of the specimens had a thin, almost transpar-

ent epiphragm at the aperture, while occasionally it was deeper

seated, thicker and white.

The apex is rather conical, the apical whorls are corneous, while the

last whorl has strong irregular wide-spaced riblets and a dark base,

often outlined by a revolving bluish stripe. |The body of the shell

is a uniform bluish-white, and occasionally a specimen has the base of

nearly the same color. In a somewhat wide experience of collecting

this species, I have never seen it so abundant. Associated with it were a

few Polygyra carpenteriana and rarely a Glandina truncata minor.

In the Manual of Conchology, Vol. xiv. p. 215, Pilsbry states

that Mr. S. N. Rhoads found five specimens of the Certon incanum

on Virginia Key, but that he thought they had probably been drifted

there, and Pilsbry believes this key to be the extreme northeastern

limit of the species. ‘* Baker’s Haulover”’ is eight or nine miles

north of the extreme northern end of Virginia Key and is on the

mainland. I followed up the beach from the ‘ Haulover ”’ for a half

mile perhaps, but there seemed to be no diminution in the numbers of

specimens at the farthest point reached.

SEXUAL DIMORPHISM IN STROMBUS PUGILIS LINNE.

BY HAROLD SELLERS COLTON.

Sexual dimorphism does not seem to be common among the Gaster-

opoda. It can occur only in the sub-class Streptoneura, in which the

sexes are separate. Cases are seldom reported. When they are,

they are hidden amid a mass of facts in some large work. I find

that sexual dimorphism has been noticed in Margarita helicina* and

38, 1904.

THE NAUTILUS. 139

Buccinum undatum' by Morse, in Crepidula® by Conklin, in Rissoa

aculeus* and Littorina littorea* by Jeffreys, and in Pulgur carica by

Burnett Smith.° As far as I can find out, no one has reported it in

Strombus pugilis.

The material was collected to determine if the variety alatus was

but a case of sexual dimorphism, and if not was there any such dif-

ference. I collected most of the individuals after asevere “norther”’

in the latter part of January which had cast them up in moderate

numbers on the beach of Sand Key near Clearwater Harbor, Florida.

Of those I examined, nineteen were males and nine were females.

The variety alatus differs from the type in that it lacks the char-

acteristic tubercles on the body whorl. Forty-four per cent of the

females and twenty-six per cent of the males showed a tendency to

be smooth. Of these observations

and the ones to follow, the probable mes

error is so very large, on account of |

the small number of individuals at

hand, that only where the differ-

ences are pronounced, are the results

of value.

On the material at hand I made \

thefollowing measurements;-(Fig.1) \

the length AB, the width CE, the

angle at the apex, the columellar

angle, and the aperture FG. On

account of the ornamentation of the

shell, the width CE and the apical

angle were found to be so variable

as not to be favorable for compar-

ison. ‘The ratio of AB to FG was

in the case of females larger than in ‘e

the case of the males. If this be ,

true, and I have too few individuals

to be sure of it absolutely, a very interesting feature is shown. The

aperture of the male is larger than that of the female. Thisis true

also in Nautilus pompilius.’ |

The average columella angle CDE is for males 37.4° and for

females 40.4°. The columella angle of the females is larger than

that of the males. This is characteristic, and it is possible to sepa-

rate the males from the females in a large series at a glance with

very few errors. One male, however, showed the female angle and

one female the male angle.

The results of these observations indicate that the relation of the

variety alatus to the type is not of sexual character, that the aperture’

of the male may be a trifle wider than that of the female, but the

columella angle is a true case of sexual dimorphism.

NEW SPECIES OF LYMM ZEA.

BY F. C. BAKER.

Lymnzxa owascoensts nov. sp.

Shell small, elongated, turreted, rather thin; color light horn;

surface shining, marked by close-set lines of growth; in some speci-

mens there is a tendency to form raised, keel-like ridges, as in

malleated forms of Lymnza ; apex small, round, of the same color as

the rest of the shell; whorls 54, shouldered, rather flat-sided ; spire

elongated, sharply conical; sutures deeply impressed; aperture

roundly ovate, about two-thirds the length of the entire shell; outer

lip thin, inner lip erect, causing the aperture to be almost continu-

ous; columella rather broad, flattened, somewhat thickened by a

callus but without a plait; umbilicus round, wide and deep, exhibit-

ing one volution; the base of the shell is roundly flattened.

Length 8.50; width 3.50; aperture length 3.50; width 2.00 mill.

Length 8.75; width 4.00; aperture length 3.50; width 2.00 mill.

This distinct little shell may be known by its turreted shell, long

spire and large, open umbilicus. Its nearest ally is deszdiosa.

Lymnexa bryanti nov. sp.

Shell small, thin, robust, pointed ; color light horn; surface rather

dull, marked by rather indistinct lines of growth, but without im-

pressed spiral lines; the base of the shell is marked by several indis-

tinct spiral ridges, and the last whorl is malleated in some specimens;

whorls 44-5, rounded, roundly shouldered, rapidly increasing in

diameter; the last whorl is large and quite convex; spire acutely

‘conical, shorter than or as long as the aperture; sutures well im-

pressed ; aperture elliptical or elongate-ovate; columella a trifle

thickened, without a plait, the callus turned back and appressed to

the parietal wall as in cubens?s; umbilicus distinct and rather widely

open.

This little shell is related to cubensis but is easily distinguished by

its thinner shell, more pointed spire, less rounded whorls and more

elongate aperture. The shape of the aperture and the form of the

columella are different from those of humilis.

Lymnea stagnalis var. higleyt, new variety.

Shell ovate with short spire and wide, spreading aperture which

is twice the length of the spire; whorls rather flat-sided, the last

somewhat shouldered; collumellar plait very large, thick, heavy,

shining, white; aperture widely flaring, the upper part somewhat

shouldered ; umbilicus tightly closed by the closely appressed, reflec-

ted, columellar callus. |

Length 38.00; width 22.00; aperture length 25.00; width 17.00

mill. (Walker).

Habitat ; Michipecoten Bay, North Shore, Lake Superior.

In a lot of specimens of Lymnaea stagnalis sent to the writer for

examination by Mr. J. H. Ferriss, there were three specimens which

differed markedly from any described American form of this species.

The nearest variety seems to be Hemphill’s ocezdentalis, but that

form is decidedly more shouldered on the body whorl, the aperture

does not flare and the spire is more “ pinched.” The color is a clear

translucent whitish horn. The writer has seen no European variety

exactly comparable with this variety. .

It is named in honor of Prof. William K. Higley, Secretary of

the Chicago Academy of Sciences.

GLOCHIDIA OF UNIO ON FISHES.

BY CHAS. H. CONNER,

A short time ago (Feb. 25, 1905), while hunting especially for _

fresh-water shrimps, I obtained some young minnows and sun-fish

(Hupomotis gibbosus). Upon examination of the latter, I found

several Glochidia, apparently of Anodonta cataracta Say, clinging to

the anal and caudal fins.

THE NAUTILUS. 1438

On Monday, Feb. 27th, I had the honor of submitting the speci-

mens, 7m situ and intact, to Dr. Pilsbry and Mr. Vanatta, of the

Academy of Natural Sciences, for verification, and they confirmed

the discovery.

As no record of observed parasitism in America of Glochidia has

been made in any scientific journal that I am aware of, it was a

great pleasure to find them living, and confirm the observations

made in Europe. |

The fish were taken from the most eastern of the three connected

ponds at Westville, N. J.

NOTES.

MARRATT AND THE ConcHOoLoGIA Icontca.—In the February

NavtTIiLus, p. 120, in the extract from ‘‘ The Museums Journal,”

concerning the late F. P. Marratt, it is stated that he was the author

of the monograph on Oliva in Reeve’s ‘“ Conchologia Iconica.”

This is an error which might be corrected if you think it necessary.

When Lovell Reeve wrote that monograph in.1850, Marratt was

unknown as a conchologist.

Of the “ Conchologia Ivonica”? Reeve was author of Vols. I.—

XIV., and as far as Zornatella in Vol. XV. The rest of that vol-

ume, commencing with Pyramidella to the end, and Vols. XVI.-

XX. were the work of the late G. B. Sowerby.—Epe@ar A. SmitH,

British Museum (Natural History).

Norte on THE Genus AporEeMA DaLti—This group, of which

Pholadonya arata Verrill is the type was named in 1903. But I

am informed that Aporema was used in 1890, by Scudder, for an in-

sect, and the molluscan genus therefore requires a new name. _ I

propose for it Panacca.—Wm. H. Datu.

Nore on Tricnuopina ANncEy.—lInasmuch as the name Tvrich-

odina, proposed by Ancey in 1888 for an Achatinoid land shell (cf.

Man. Conch. pt. 67, p. 182) was used in 1830 by Ehrenberg for a

genus of Foraminifera, I would propose that it be replaced by

Petriola.—Wm. H. Datu.

144 THE NAUTILUS.

Tue Genus VaucnertA Patiary.—Mr. Pallary describes

(Journ. de Conch. ’04, p. 7.) a shell supposed to be that of a slug,

under the name Vaucheria tingitand. M. Dautzenberg has recently

received fresh specimens, which proved to be plates (the tergum) of

Pollicipes cornucopia, a stalked barnacle of European seas. The

supposed new genus therefore becomes a synonym of the Cirrhipede.

SNAILS IN SEPULCHRES.—While I was very recently conduct-

ing the exhuming of quite a number of Indian skeletons, within the

corporate limits of Des Moines, Iowa, I found, very much to my sur-

prise, several living specimens of Zonitoides minusculus (Binn.) and

Helicodiscus lineatus (Say,) very snugly associating with the long dead

and.buried aborigines. They attracted my attention by being among

some of the small white beads, which were about the same size and

color. I would often pick up a shell fora bead. They were min-

gled with decayed fibrous roots, fragments of blankets etc., in among

the bones, often in the crevices of broken and decayed bones. Every-

thing was in a very advanced stage of decay, denoting in the neigh-

borhood of seventy-five years’ burial; the evidence showed that the

bodies had been wrapped in blankets and buried in wooden boxes.

In a number of instances the entire outfit, box and all, was reduced to

a mere trace less than half an inch in thickness; others were two or

three inches thick, and a few produced fairly well-preserved skeletons.

All contained shells of the above-named species. The burials lay

from eighteen inches to three and a half feet deep, in a very loose, fine,

sandy, Pleistocene loam. If the snails were at home, as they appar-

ently were, is not their association with dead mens’ bones an unusual

occurrence ?-T. Van Hynine, Supt. Mus. State Hist. Dept.

Des Moines, Ia.

In the last number of the Proceedings of the Malacological So-

ciety of London, Dr. von Ihering adds three new species to the

genus Tomigerus, the first for many years.

A new species of Achatina, A. morrelli, is described by Mr,

Preston, from the Zambesi river. It seems to be closely related to

A. capellov. Furtado—H. A. P.
