The description of Orthurethrous snails is continued in this- 
volume, the remaining groups of Ferussacidce and the Partu- 
lidcs being described. In treating of the latter family, the 
author has had the advantage of studying the types and other 
specimens of the late Dr. W. D. Hartman, now forming part 
of the collection of the Carnegie Museum at Pittsburgh. The 
conclusions reached in the monograph now published have 
thus been based upon the material of two large collections. 
The liberality and courtesy of the Trustees of the Museum 
and of the Director, Dr. William J. Holland, are here grate- 
fully acknowledged.

Explanation of plates 



About ten years ago the writer pointed out the existence 
of three great groups in the monotremate land snails, based 
upon the structure of the pallial organs: SIGMURETHRA, 
HETERURETHRA and ORTHURETHRA. The first group includes 
a very large majority of the land snails now existing, which 
have been described in volumes I to XVIII of this work. 
The Heterurethra are chiefly represented by the genus Sue- 
cinea. Finally the group Orthurethra is made up of a series 
of families which retain primitive pallial structures like the 
Basommatophora. They are the scattered descendants of 
snails of long ago of the first land-snail fauna. With the 
rise of the Sigmurethra, these primitive snails declined. On 
the continents they take a minor role, and seem to exist by 
grace of their insignificance (Pupillidcz, Valloniida, Ferus- 
sacida), though one family, the Enidce, contains snails of 
moderate size. On the Pacific islands, where the Sigmurethra 
are represented by only a few low forms, Orthurethra are 
still dominant. In this island world the Partulidce, Amastrida, 
Ackatmellida and Tornatellinidce comprise the most con- 
spicuous elements of the snail-fauna. 

The following families are now comprised in the group 
Orthurethra : 

Valloniidae (See Vol. VIII, p. 247, and IX, p. 282). 

Enidae (Buliminidce of authors). Pala&arctic, Oriental, 

Pupillidse (Pupida of authors). World- wide. 

Partulidae (this volume, p. 155). Polynesia, Melanesia, 



Ferussacidae (Vol. XVIII, p. 211; this volume, p. 1). Hoi- 
arctic, Oriental, African, Neotropical. 

Amastridoa (Vol. XXI). Hawaiian Is.; Juan Fernandez. 
Achatinellidse (Vol. XXI). Hawaiian Islands. 
Tornatellinidse (Vol. XXII) . Pacific Islands.

The shell is imperforate, very small and slender, very 
narrowly lanceolate, with obtuse, rounded, smooth apex; 
smooth, fragile, transparent (weathering to opaque white); 
aperture usually less than half the total length, piriform; outer 
lip arching forward in the middle, acute; columella concave, 
more or less distinctly truncate at base, usually somewhat 


calloused. Animal blind, or at least without pigmented eyes. 
Jaw composed of many narrow plaits. Radula with 11, 1, 11 
teeth in C. acicula, 18, 1, 18 in 0. gundlachi, the central tooth 
much smaller than the laterals, with a tricuspid reflection. 
Laterals symmetrical, tricuspid. Marginal teeth low, wide, 
with two low, denticulate cusps. The genitalia, as figured by 
Lehmann for C. acicula (pi. 15, fig. 1) have the duct of the 
spermatheca very short. An appendix, enlarged at the end, is 
terminal on the penis. There is also a short accessory organ 
anteriorly on the penis. 

Type C. acicula Mull. Distribution, Europe and most tropi- 
cal and subtropical countries. 

An excellent account of Cascilioides acicula has been given by 
Mr. L. E. Adams, as follows: " Methods of Progression. Usually 
the shell is dragged along the ground after the animal, though 
more rarely it is lifted to a horizontal position (pi. 1, fig. 6). 
On two occasions I observed the animal protrude its head under 
the shell towards the spire and progress in that direction, forc- 
ing the shell along the ground in front of it, apex first, and then 
lift the shell over its head at an angle of about 45 degrees, and 
continue its march in that position (fig. 5). The progression 
is always by slow jerks, and not a continuous glide. I have 
not observed the shell carried in the position of Jeffrey's figure 
(British Conchology, Vol. I, pi. 7, fig. 18), though Nilsson 
says * the animal sometimes carries its shell erect, but generally 
drags it along depressed.' 

" Texture and Form of the Animal. I was much struck with 
the extremely flexible and elastic nature of the animal. I have 
observed one emerge from the shell as it lay flat, on a hori- 
zontal surface, and make a complete circle with its head and 
tail, without moving the shell. It is also remarkable how far 
the animal will protrude from the shell, and how slender an 
attachment connects the head and foot with the part within the 
shell. The end of the tail is often curled up. Along the neck 
;ind down the front of the head are two mucus sulcations on 
either side of the dorsal line (pi. 1, fig. 8). The tail is pointed 
and sharply carinated; from the dorsal ridge mucus sulcations 
descend to the lower edge (fig. 7). 

" Eyes and Tentacles. Jeffreys' enlarged figure (Brit. Conch., 
Vol. I, pi. 7, fig. 19) is not quite accurate. He seems to have 
taken his description from Nilsson, and it may be doubted 
whether Jeffreys himself examined the animal with sufficient 
care. Nilsson had evidently studied the animal, but he was 
not correct in describing the upper tentacles as ' not thickened. ' 
In all the specimens that I have observed the upper tentacles 
are certainly slightly bulbous when fully or nearly fully ex- 
tended, though this does not appear when they are only slightly 
protruded. Nilsson, however, correctly remarks that the apices 
of the upper tentacles are not ( marked with a black spot.' 
Now Lamarck (to whom Nilsson refers) seems to have been the 
only one to observe the colorless eyeball, and he did not recog- 
nize them as such. Nilsson says (quoting Lamarck) "In this 
species no eyes indeed are exposed, unless they are white, like 
the tentacles themselves. These, indeed, are terminated by a 
convex surface, very smooth, very shiny, surrounded by a 
slightly impressed ring; which surface doubtless answers to the 
eye of other terrestrial mollusks. But this animal, probably 
because it lives underground, where it cannot use eyes, appears 
to us plainly to lack eyes.' Now I have noticed that these 
peculiar convex endings with a constricting ring are in fact eye- 
balls, and also that they are retractile, but whether they have 
retained the power of sight in spite of their loss of pigment, I 
am not prepared to say (see fig. 8). As far as my observation 
goes, the animal is insensible to light, though it will crawl 
straight away to a heap of moss; the direction, however, may 
be determined by scent alone. If it is deficient in sight it cer- 
tainly uses its tentacles to all appearance in the same manner as 
its more favored brethren. I may mention in this connection 
that an albino specimen of Limax maximus, whose eyeballs were 
also destitute of pigment, seems to act in a perfectly normal 
manner. Though my observations on this point (Journal of 
Conch., Vol. 9, p. 24) tend to show that this species is lacking 
in sight, I am not aware to what degree of perfection the vision 
of terrestrial mollusks attains, but I have noticed that Oydostoma 
elegans and Helix pomatia seem sensitive to the approach of a 
large' object." (Lionel E. Adams in The Journal of Conchol- 
ogy, Vol. 9, p. 297. ) 


Cdecilwidea is well known to inhabit graves. Gaudry found 
them in lacrymatories unearthed from Grecian tumuli. Rev. 
H. Housman records that near Chichester in "an early British 
burying-ground many skeletons were found. The bones, which 
lay about three feet below the surface were infested with A. 
adada" (Journ. of Conch, iii, 1882, p. 317). In North- 
amptonshire Messrs. Wright and Adams found Ctedlioides 
abundant to a depth of 4-J ft. , in a place where skeletons of men 
and horses have occasionally been discovered (J. of C. viii, 
1897, p. 395). J. W. Horsley reports them similarly from a 
Saxon cemetery near Witney (J. of C. ix, 164); and in Germany 
Professor von Martens has recorded the presence of a great num- 
ber of large fresh specimens in a human skull dug up at Bern- 
burg (Nachrbl. d. Mai. Ges. 1883, p. 60). 

Definite information upon the food of Csecilioides is wanting, 
but they probably feed upon vegetable matter, such as subter- 
ranean fungi or possibly fine rootlets. 

The European species of Csecilioides have no doubt been multi- 
plied beyond reason, yet without a critical study of the types 
it is impossible to say how many recognizable races exist. M. 
Bourguignat and his friends had an agreeable custom of describ- 
ing "species" from single selected specimens, ignoring connect- 
ing forms. Published figures of shells they had never seen 
occasionally served as a basis for supposed new species; so that 
in the identification of real shells there is some excuse for pass- 
ing over much work of these authors with a light heart and 
careless eye. I have neither the time nor type-material to at- 
tempt a critical revision of these forms. It is a work which 
properly belongs to some European student who will make a 
study of the local races, of the significance of variations, whether 
individual or racial, and finally he must study Bourguignat's 
types. This work demands great application and large series 
of the shells, unprejudiced by selection or determination. I 
have been able to do little more than give an account as full as 
the original sources admit. The American forms are treated 
more fully, my material being ample, and the literature less 

The generic name has been variously spelled, but the earliest 


valid form is undoubtedly Csecilioides, in reference to the blind- 
ness of these tiny subterranean snails. Aciculina of Wester- 
lund is an absolute synonym of Cxcilioides, having for type the 
same species, 0. acicula. 

Gsecilioides occurs in typical species in the Miocene and Plio- 
cene, the following species being known. All were described 
under the name Cxcilianella.

C. a. irregularis Sacco 1885 (t. c., pi. 6, f. 26) is a form with 
very rapidly descending last whorl, requiring comparison with 
recent forms.

Species of the Atlantic Islands. 
1. C. SPICULUM (Benson). 

Shell imperf orate, subulate-cylindric, very slender, hyaline, 
polished; spire lengthened, the apex obtuse; suture impressed, 
margined. Whorls less than 6, slightly convex, the last one- 
third the length of the shell. Aperture vertical, tapering-piri- 
form, rounded basally; lip slightly obtuse and a little arcuate. 
Columella deeply, obliquely truncate at base, and calloused at 
the parietal margin. Length 4, diam. 1, aperture 1.33 mm 

Cape Verde Is.: S. Antao (Dohrn), and S. Vicente, near the 
Duke's Head Mountains (E. L. Layard).

xvi, 1869, p. 10. MORELET, Journ. de Conchyl. 1873, p. 242. 

According to Wollaston, this species differs from C. acicula 
by being smaller, narrower, thinner, paler, more highly polished 
and more transparent; its spire, which has a volution less, is 
shorter and a little more obtuse at the apex, its suture is less 
oblique, its columella is relatively somewhat longer and 
etraighter, and more flexuous, and its entire outline is both 
narrower and more fusiform. 


2. C. EULIMA (Lowe). 

Shell linear, very narrowly cylindric, very slender, generally 
very indistinctly curved; spire long subconic-cylindric, the apex 
obtuse; suture very oblique, distinctly margined. Whorls 6, 
flat, the middle ones long. Aperture short-obovate, acuminate 
above, entire and arcuately rounded below, much shorter than 
the spire; parietal wall uniplicate in the middle, the fold trans- 
verse, entering; peristome simple, acute, the margins joined by 
a somewhat thick callus, the right margin rounded, continued 
in a regular curve into the basal and columellar margins. Col- 
umella curved and slightly twisted, not abruptly truncate, but 
gradually and easily passing into the basal margin. Length 
2.5 to 3, diam. 0.75 lines (WolL). 

Madeira: probably in the Funchal district, recent; Porto 
Santo, very rare, fossil (Wollaston). 

Achatina eulima LOWE, P. Z. S. 1854, p. 201. WOLLASTON, 
Testacea Atlantica 1878, p. 244. 

"The most important feature which separates the A. eulima 
from the acicula consists in the presence of a conspicuous medial 
plait on its ventral paries ; but it has other characteristics also 
which combine to separate it from that species. Thus it is not 
only longer, more cylindric, and proportionately still slenderer, 
with a tendency to be obsoletely bent (as in the marine genus 
Eulima^ but its whorls (particularly the intermediate ones) 
are altogether more lengthened-out and flattened, and its aper- 
ture is relatively a little shorter, as well as broader (and more 
rounded) posteriorly, the basal margin being more obtusely 
arcuate, and merging almost without an intervening angle into 
the columella, which is narrower gradually (and is not abruptly 
truncate) behind. The suture is exceedingly oblique, and its 
surface is of a hyaline white." (Wottaston). 

This species apparently belongs to the section Rhaphidiella of 
Maltzan. See species No. 6. 

3. C. NYCTELIA Bourguignat. PI. 2, figs. 32, 33. 

This shell has the usual acicular shape, clear corneous texture 
and smooth surface. Whorls 5J, very slightly convex, the 
penultimate and preceding whorls widening more rapidly than 


those above on account of the more rapid descent of the last two 
turns of the suture. The suture is distinctly marginate. The 
outer lip is strongly convex in profile view, the greatest con- 
vexity being below the middle. Columella strongly concave, 
not heavily calloused, narrowly, subvertically truncate at base. 
Parietal callus hardly perceptible. Length 4.1, diam. 1.3 mm. 

Madeira: Under stones in dry places (Albers); Punta Sao 
Lourenco. (M. Grabham).

59, pi. 15, f. 17, 18; renamed Caecilianella nyctelia BOURGUIGNAT, 
Rev. et Mag. de Zool. 1856, p. 430, pi. 12, f. 21, 22 (copy from 
Albers). Achatinan., PFR., Monogr. iv, 626. 

This species is distinguished from G. acicula by the irregular 
increase of its whorls, the antepenultimate or penultimate sud- 
denly widening more rapidly than those before, and by the 
narrow, subvertical truncation of the columella, that of acicula 
being wider and more approaching horizontal. The species of 
Bourguignat was based solely upon Albers' account; and the 
latter, in my opinion, applies to this form rather than to the 
real C. acicula. Bourguignat had not actually seen the 
Madeiran shell. 

The Sicilian C. actoniana, rizzeana and petitiana are apparently 
identical specifically with nyctelia, or at all events, there seems 
to be no difference in the shells. How many other of the 
11 species" are really the same I do not know. Fig. 32 repre- 
sents an adult shell from Punta Sao Lourengo; fig. 33 a young 
shell from another locality, length 3.6, diam. 1.1 mm. 

Var. maderensis n. v. PI. 2, figs. 34, 35. The shell is com- 
posed of 5 nearly flat whorls, the last turn of the suture de- 
scending more rapidly. Aperture more than half the total length, 
lanceolate; columella slightly concave, rather lightly calloused, 
and somewhat widely truncate at the base. Length 4, diam. 
1.25 mm.

Central European Species. 
4. C. ACICULA (Miiller). PI. 1, figs. 1, 2, 5-8. 

"Shell turreted and slender, transparent, very thin, highly 
polished and iridescent, ivory-white, with a yellowish tinge on 
the upper part in fresh specimens (owing to the color of the 
liver), perfectly smooth and polished when examined with a 
lens of ordinary power, except a few faint and irregular wrinkles 
in the lines of growth, but under a microscope exhibiting deli- 
cate and close-set spiral striae. Periphery rounded. Epidermis 
exceedingly thin and forming a mere film. Whorls 5J, not 
convex, but compressed and drawn out, rapidly increasing in 
size; the last occupying about one-half of the shell. Spire very 
obtuse and rounded at the point. Suture moderately deep and 
oblique, apparently margined on the under side by reason of 
the upper part of the succeeding whorl being seen through the 
pellucid shell; mouth oblong, contracted by the penultimate 
whorl, narrowing above into an acute angle, slightly widened 
and rounded below, but interrupted by a deep notch at the base 
of the pillar lip." Outer lip thin and flexuous. Pillar lip 
thick and curved. Inner lip consisting of a slight deposit of 
shelly matter, which is spread on the pillar. Length 0.175, 
breadth 0.04 inch (Jeffreys').

Gwyn Jeffreys' description of this common species is given. 
It seems to be a rather variable form, but the limits of variation 
in this group are little understood. A large proportion of the 
specimens in collections are from drift debris of rivers, hence 
forms from various colonies and diverse stations are mingled in 
unwonted company. Such lots are misleading in the study of 

Var. elongata Locard. Of a slimmer, more lengthened form. 

Var. ventricosa Locard. Of the same size (not over 4.5 mm. 
long), but the shape is a little more ventricose, more swollen at 
the base (Locard, Conchyliologie Portugaise, in Archives du 
Mus. d'Hist. Nat. de Lyon, vii, 1899, p. 141). 

Var. festuca Porro. Whorls only 4; size smaller, alt. 2, diam. 
0.5 mm. Como and Varese, Italy. (Achatina acicula var. fes- 
tuca Porro, Malacologia terr. e fluv. della Prov. Comasca, Milan, 
1838, p. 52.) 

Var. eburnea (Risso). PI. 1, fig. 9. Shell very long fusi- 
form, very fragile, glossy, pellucid, ivory-white; spire long, the 
apex obtuse; whorls 7, regularly increasing, flattened or slightly 
convex, separated by a deeply impressed suture, the last one- 
third the total length. Aperture piriform, dilated below; colu- 


mella twisted, strongly truncate, not reaching the base; right 
margin arching forward; margins joined by a callus. Length 
6, diam. 1.25 mm. (</.).

Var. enhalia Bgt. PL 1, fig. 10. Very minute, composed of 
5 flattened, irregularly increasing whorls, the last over one- 
third the total length. Right margin of the lip not arching 
forward; margins of aperture joined by a thin callus which has 
a more or less obsolete tubercular prominence at the insertion of 
the outer lip. Length 3.5, diam. 1 mm. Brittany: Around 
Cancale (Cotes-du-nord), along the cliffs almost at the high tide 
line. (Bgt., Malac. terr. et fluv. de la Bretagne, I860, p. 158, 
pi. 2, f. 14-16.) 

Var. anglica Bgt. According to Bourguignat, this is dis- 
tinguished from acicula by the larger size, length 8, diam. 1.5 
mm. the whorls of the spire more convex, the suture deeper, 
not margined, the aperture rounded, and the columella strongly 
truncate. England. (C. anglica BGT., Rev. et Mag. de Zool. 
1856, p. 384, pi. 12, f. 4, 5.) 

This "species" is a good example of Bourguignat at his 
worst. There really was no type specimen of anglica; nothing 
but Reeve's figure in the Conchologia Iconicav, pi. 20, f. Ill, 
which Bourguignat described in formal phrase, while his artist 
redrew it enlarged for his plate. The citation of Reeve is curi- 
ously falsified in name of the work, number of the figure and 
date, almost concealing the real source of all of the information 
extant upon " C. anglica" Whether the English form has any 
racial characters or not must be left for English students to 
decide. I have never seen English examples so large as anglica 
is claimed to be; but the size was probably not carefully meas- 
ured from the shell, but merely estimated by the eye. Reeve's 
Iconica is very unreliable in all relating to minute shells, though 
the figures of large species are admirable. 


Var. nodosaria Boettger. PI. 1, fig. 16. May be near var. 
anglica, but differs by its far smaller size. With 5 volutions 
the Caucasus form has relatively wider and distinctly more 
convex whorls, so that the aperture appears more widely ob- 
long. Length 3.5, diam. 1.12 mm. (Bttg., Jahrb. D. M. Ges. 
vi, 1879, p. 398, pi. 10, f. 10).

Shell minute, turrite-oblong, slender, polished, diaphanous, 
whitish, the apex obtuse; whorls 6, a little flattened, separated 
by a superficial, duplicated suture, the last whorl over one-third 
the total length. Aperture piriform-oblong; peristome acute, 
simple, unexpanded, the right margin slightty arching forward; 
columella straight, slightly truncate, margins joined by a thin 
callus which bears an obsolete tubercular projection on the con-

This form is probably distinct from C. acicula. It is more 
slender with smaller aperture, and a rather heavy callus, which 
forms an entering ridge or nodule below the middle of the par- 
ietal margin. While this structure is conspicuous in typical 
liesvillei^ yet it varies in development, and is traceable in occa- 
sional specimens of C. acicula. Dr. Boettger has identified 
liesvillei from debris of the Kura at Borshom, Caucasus. The 
specimens (pi. 1, fig. 15) differ from typical acicula by the ob- 
solete parietal fold in the middle of the base of the last whorl, 


and the less curved columella, which is only very obliquely and 
weakly truncate at the base. Length 5.25, diam. 1.62 mm. 
(Jahrb. D. M. Ges., vi, 1879, p. 398, pi. 10, f. 9.) 

Var. gemmellariana (Benoit). PL 2, fig. 28, 31. Shell 
elongate-cylindric, slender, polished, glossy, hyaline, whitish; 
spire turrited, slightly tapering, the apex mamillate; suture im- 
pressed, widely margined, whorls 6, subplanulate, not rapidly 
increasing, the last cylindric, as long as the spire. Columella 
subarcuate, at base narrowly and obsoletely truncate. Aperture 
narrow, oblong-acuminate ; peristome simple, unexpanded, 
acute, the margins joined by a very thin callus, right margin 
arching forward. Length 4.4, diam. 1.5, aperture 1.66 x 0.75 
mm. (Ben.)

et mag. zool. xvi, 212. 

Benoit' s original figure is copied, fig. 31. I have also illus- 
trated one of several specimens before me, received from Benoit. 
This shows a form probably not distinguishable from liesvillei 
Bgt., having a slightly contracted- attenuate spire, the whorls 
distinctly convex, the convexity chiefly close below the suture. 
There is a conspicuous, spirally entering callous ridge on the 
parietal wall close to its junction with the columella, but other- 
wise the parietal and columellar margins form nearly a straight 
line. As usual, the first whorl increases very fast, the next 
whorl scarcely widens, and the last 2 whorls increase regularly. 
Length 4.4, diam. 1.3 mm.; whorls 5. 

Younger shells agree better with Benoit' s description, yet 
even these show the trace of a callous lamella. I am disposed 
to place the form in the synonymy of liesvillei. 

Var. tiberiana (Benoit). Vol. xix, pi. 51, fig. 5. Close to 
C. gemmellariana but distinct by the greater size, the upper 
whorls more slender and delicate, the last whorl much more 
swollen, and by the greater number of whorls, 6, and the piri- 
form aperture. (Ben.) 

Sicily: Palermo.

Var. cristallina (Benoit). Shell turrite, whitish, smooth, 
translucent, the apex obtuse, spire composed of 5 slightly convex 
whorls separated by a well-marked suture. Last two whorls 
forming two-thirds the total length. Lip simple, acute, the 
margins joined by a callus. Aperture piriform; truncation of 
the columella strongly marked. Length 5, diam. 2 mm. 
Sicily : Spadafora, near Messina. (C&cil. cristallina BEN., 
Catalogo, 1881, p. 90). Related to C. gemmellariana. 

Var. hyalina (E. A. Bielz) PI. 1, figs. 3, 4. The shell is 
very long and narrow, composed of fully 6 very slightly convex 
whorls, the last 4 rapidly increasing, the suture very oblique, 
but descending much less rapidly near the aperture. Aperture 
small, piriform. Columellar callus rather thin, but in certain 
positions its upper edge is barely visible as a slight prominence 
on the parietal wall. Length 5, diam. 1.25, aperture 1.7 mm.

(exclusive of synonymy). 

Bielz intended his name to replace that of acicula, but he 
gave a description of the Transsylvanian form, which proves to 
be distinct from acicula by its greater elongation. It stands 
close to liesvillei, but is possibly separable by the more delicate 
columellar callus and the absence of a distinct callus on the 
parietal wall. The specimen figured was received from Bielz. 

Var. uniplicata Bourguignat. PI. 1, figs. 13, 14. Shell 
minute, turrite-oblong, slender, very fragile, diaphanous- 
whitish, crystalline, smooth; apex obtuse, mamillate, composed 
of 6 nearly flat or slightly convex whorls, which increase 
rapidly and unevenly, and are parted by an impressed, not 
duplicated, suture; the last whorl half the total length or more. 
Aperture piriform-oblong; columella uniplicate above, a little 
twisted, truncate at the base; peristome acute, unexpanded, 
simple, the right margin arching forward, columellar margin 
somewhat calloused. Spreading, the margins joined by a thin 
whitish callus. Length 4, diam. 1.25 mm. (Bgt.~}.

Cacilianellauniplicata'BGT., Malacologie d'Aix-les-Bains 1864, 
p. 55, pi. 2. f. 3-5. 

The columella "a little concave, ornamented in the upper 
part with a lamelliform fold, and having a distinct truncation 
at the base ' ' seems to be the chief characteristic of this form. 

Var. aglena Bgt. PL 1, fig. 18. Shell approaching espe- 
cially the C. liesvillei, but is distinguished by the mamillate 
summit, non-margined suture, 7 whorls, and especially by the 
aperture, in which the penultimate whorl has scarcely any con- 
vexity, but forms nearly a straight line with the columella. 
Length 5, diam. 2 mm. Ville-au-Bois-les-Vendeuvre, Aube, 
France (Bgt., C. aglena, Rev. et Mag. ZooL, 1857, p. 15, pi. 1,

Var. boettgeri Hesse. PL 1, fig. 17. Differs from the type 
by the smaller size, more slender shape, angulate columella, 
whorls more rapidly increasing, the penultimate as high as the 
upper ones. Length 3, diam. scarcely 1 mm. Tinos, Grecian 
Archipelago, in flotsam of a small brook. Differs from liesvillei 
by its slimness and the shape of the columella, which has an 
angle in the place where there is an obsolete fold in liesvillei. 
(Hesse, Jahrb. D. Malak. Gee., ix, 1882, p. 332, pi. 12, fig. 8.) 

Forms of Spain and Portugal. 

The Iberian forms have not been figured. In a group where 
with the closest comparisons of specimens, species are difficult 
to distinguish, mere descriptions are barely worth the paper 
they are written on. The student will find all published in- 
formation below. C. acicula and C. nanodea are also recorded 
from the Iberian peninsula. 

C. vandalitice Servain. The whorls increase regularly and 
rapidly; the suture does not descend much. The last whorl 
has a regular, median convexity, not inferior, as in belonidaea. 
The spire tapers gradually. The outer lip, instead of descend- 
ing a little below the columellar extremity, forming an angular 
part at the base of the aperture as in belonidaea, is on the con- 
trary convex and rounded to the columellar border, which is 


shorter and more strongly truncate. As the increase of the 
whorls is regular and the convexity about equal in all there is 
not the contraction at the left side between the penultimate and 
last whorls, noticed in C. belonidaa. The simple peristome is 
not thickened within, and is not patulous at the base of the 
aperture. Length 6, diam. 1.75, aperture 2x1 mm. ; whorls 7.

C. castroiana Locard. Shell of relatively great size, of a fusi- 
form, long-conic shape; spire very narrow, acuminate, com- 
posed of 6 slightly convex whorls, the first three increasing 
slowly and regularly, the following two much larger, the last 
whorl greatly developed, rounded at the base, three- sevenths 
the total length. Suture impressed, with a bordering line 
below. Summit small, obtuse, rounded. Aperture small, 
piriform, slightly over two-sevenths the total length, contracted 
above, well rounded at the base. Peristome simple, unex- 
panded and acute; right margin arching a little forward, the 
profile broadly arcuate; columellar border slightly sinuous, 
truncate, not reaching the base of the shell; the margins joined 
by a visible callus. Shell thin, quite solid, diaphanous^ 
smooth, whitish. Length 7, diam. 2 mm. (Loc.~). 

Portugal: Faro, Algarve. 

Caecilianella c., LOCARD, Conchyliologie Portugaise, in Archives

Said to be larger, more slender, longer and more conic than 
C. acicula, with less regularly coiled and less convex whorls, 
duplicated suture, smaller and narrower aperture, etc. 

C. ribeiroi Servain. This species is remarkable for the oblong- 
acuminate shape of the spire as far as the two upper whorls, 
which are cylindric; for the progressively accelerated increase 
of the whorls, the suture also more and more steeply descending. 
The last whorl is regularly long-convex. The aperture is quite 
excised by the convexity of the penult whorl; columellar mar- 
gin short, strongly projecting, strongly truncate at the base, 
obliquely arcuate from left to right, giving the aperture in the 



ICO ""' 


upper part a very distinctly concave contour. Length 5, 
diam. 1.5, aperture 1.5 x 0.75 mm.; whorls 6.

C. poupillieri 'Bgt.' Servain. Shell long, quite oblong- 
acuminate, of irregular spiral increase: two first whorls minute 
with nearly horizontal suture, the rest of the whorls well de- 
veloped, increasing rapidly, and separated by a progressively 
more and more rapidly descending suture. Whorls 6, slightly 
convex, lightly flattened, notable the fourth. Outer lip convex. 
Columellar margin very short, quite projecting, strongly trun- 
cate. Peristome simple, acute. Length 6, diam. 2 mm.

C. bdonidaa Servain. The upper whorls in this species are 
regularly elongate-convex, with a suture which does not descend 
much until the beginning of the last whorl, where the descent 
rapidly increases, the suture descending very obliquely. The 
last whorl is not regularly convex, but is flattened in the upper 
part and inflated below. The long-piriform aperture is narrow 
above, dilated at the base; the outer margin is straight, arcuate 
in front. The apertural convexity of the penult whorl descends 
in nearly a straight line to the columella, which is short, 
straight, indistinctly truncate below. Length 5.5, diam. 1.25, 
aperture 1.75 x 1 mm.; whorls 5.

The identity of this species, and its synonymy, have been the 
subjects of considerable variance. Unfortunately I have not 
access to de Betta's " Esame Critico" in which he figures the 


species. Westerlund's account, which I have used above, 
seems to have been taken mainly from Kuester s article of 1870, 
which was the first critical discussion of the species. 

Var. gredleri Kuester. Shell ovate-fusiform, slender, thin, 
polished, whitish, the spire rather acute, whorls a little convex, 
joined by a margined suture, the last more than half the total 
length. Aperture narrow, lanceolate ; peristome unexpanded 
acute, arching forward. Columella short, slightly arcuate, 
obliquely truncate, margins joined by a callus. Length 5.5, 
diam. scarcely 2 mm. (Acicula gredleri Kuester, Neunter Ber. 
Nat. Ges. Bamberg, 1870, p. 94). 

"One might say that this species represents a shortened, 
widened aciculoides, just as veneta seems to be a derivative of 
acicula. The slender shell is fusiform, but the greatest width is 
below the middle." The types were found at Trient with A. 
veneta by Professor Gredler. One example was found by Dr. 
Kuester at Triest. 

14. C. ACICULOIDES ('Jan' de Betta). PI. 2, fig. 25. 

Shell minute, fusiforrn-cylindric, acicular, the apex attenuate, 
obtuse, hyaline, glossy, white or gray. Whorls nearly flat; 
suture very narrowly margined; columella arcuate, the base 
narrowly truncate. Aperture ovate-oblong, lanceolate, very 
narrow; peristome simple, unexpanded, acute. Length 8.5 to 
4, diam. 1 to 1.25 mm.; whorls 6 (de Betta, 1852). 

Northern Italy: valley of the Non; near Fondo and in the 
valley of S. Romedio, in crevices of the earth and limestone 
(de Betta); Triest (Kuester).

From the notably higher, almost awl-shaped acicula this 
species differs by the entirely different, rather fusiform, cylin- 
dric shape, the much higher last whorl, half the total alt,, and 


the longer aperture, not so much receding below and less 
widened. The moderately increasing whorls are somewhat 
convex, the upper margin noticeably thickened, narrowly bor- 
dered. The base of the last whorl is very lightly arcuately 
tapering. The bend of the columella is indistinct, the trunca- 
tion at its base oblique. The ends of the peristome are joined 
by a distinct deposit. Length 5, diam. 1.33 to 1.5 mm. 
(Kuester, 1870). 

This species was quite unrecognizably described by Jan, but 
it was redescribed in 1852 by Edoardo de Betta, from specimens 
received from Jan. I have translated de Betta' s description 
and reproduced his very poor figure. Kuester ably discussed 
the form in 1870, having specimens received from de Betta, and 
others collected by himself at Triest. 

15. C. PEDEMONTANA Pollonera. 

Differs from aciculoides by the less swollen shell, slightly 
smaller size, spire a little more acute and higher, aperture

From specimens before me from Benoit. this does not seem 
to differ materially from C. petitiana except in being smaller. 
I have figured a Benoit shell measuring 4.4 x 1.3 mm. There 
is no noticeable parietal callus nodule or ridge; the outer lip is 
very strongly, evenly arched forward; and the last whorl 
descends very obliquely in the middle of its length. 

Far. petitiana (Benoit). PI. 2, figs. 23, 24. Shell elongate- 
fusiform, thin, polished, glossy, hyaline, whitish. Spire conic- 
turrite, the apex a little obtuse; suture impressed, narrowly 
margined. Whorls 6, slightly convex, rapidly increasing, the 
last nearly flat, longer than the spire. Columella subarcuate, 
abruptly truncate at the base. Aperture lanceolate, narrow. 
Peristome simple, unexpanded, acute, the margins joined by a 
very thin callus. Length 5, diam. 1.66, aperture 2x0.75 mm.

Several lots, all from Benoit, are before me. The extremely 
thin hyaline shell has a conspicuously margined suture. The 
upper part of the spire is slightly contracted. The first whorl 
increases in width very rapidly, the next \\ increase but little; 
then the width increases rapidly again, the suture descending 
more obliquely. Its descent is most oblique in the middle of 
the last whorl, somewhat less so towards its end. The outer 
lip arches very strongly forward, the greatest convexity being 
below the middle. The parietal wall has only a thin callous 
film. The colurnella is concave, has a callous edge, and is 
obliquely but quite distinctly truncate at the base. Length 
4.3, diam. 1.3 mm.; whorls 5. 

17. C. STEPHANIANA (Benoit). PI. 2, figs. 29, 30. 

Shell elongate-fusiform, rather solid, polished, milk-white. 


Spire conic-turrite, the apex rather obtuse. Suture somewhat 
impressed, margined. Whorls 6, convex, the last subovate, 
tapering at the base, longer than the spire. Columella sub- 
vertical, calloused, obliquely truncate, not reaching to the base. 
Aperture ovate-lanceolate; peristome simple, unexpanded, the 
margins joined by a rather thick callus, right margin arching 
forward. Length 6, diam. 2, aperture 2.6x1 mm. (Ben.}

This species is comparable to C. jani de B., having the 
sharply truncate columella of that, but it does not reach nearly 
the size 5.5 to 6.75 mm. long, 2.25 to 2.5 wide. C. jani has 
also a much more ventricose last whorl and distinctly more 
acute apex. (Bttg.) 

26. C. TORTA (Mousson). 

Aperture at the base a little compressed; columella incurved, 
terminating in a twisted thread. This species resembles that of 
Lombardy in general appearance, so that for the time being it 
may be regarded as a variety of it, characterized by having the 
aperture slightly contracted towards the base, and the columella 
abruptly truncate. The single example, taken at Sayda, is not 
sufficient to establish well these differences. (Mousson).

Differs from tumulorum Roth by the feebly convex whorls 
separated by a margined suture, the last whorl comprising two- 
fifths of the total length; by the parietal wall being without any 
callus, the outer margin not divergent, finally by the columella 
which is obliquely truncate a little way above the base, and 
bordered with a thread. The largest individuals are 7 mm. 
long (Mousson, 1874).

According to Mousson, there are fewer whorls than in C. 
adcula; the apex is larger and more obtuse, the last whorl is 
more cylindric, and the remarkably narrow aperture has the 
free margin descending in a straight line curving towards the 
end of the columella and without surpassing it. The columella 
is but slightly concave and is obliquely truncate at the base. 

The figures are copied from Boettger, and represent specimens 
from the drift of the Sarus river, where this species is common. 
He remarks that the examples vary quite noticeably in size but 
normally it is 4 to 4.5 mm. long, 1.12 to 1.25 mm. wide. A 
relative is C. subsaxana Bgt. , which perhaps may be a young 
form of the same species.

11 By its slim shape, approaching the cylindric, its more 
twisted whorls, deeper suture and the appearance of the aper- 
ture, C. isseli is distinguished from all of its congeners of the 
Alpic center." 

Paladilhe probably had two species mixed in his lot of C. 
isseli. The description is that of a Ctztilioides, possibly identical 
with Nevill's second species (Handlist Ind. Mus. p. 162), 
and with A. balanus of Hanley and Theobald (Conchologin, 


Indica, p. 41, pi. 102, f. 10, copied in my fig. 61 of plate 4); 
while the figure given by Paladilhe, which I have copied, seems 
to belong to C. (Geostilbia) balanus. Further investigation of 
the C&cilioides of Aden and India is much needed. Whether 
the observed differences in the columella indicate several species, 
or are extreme aspects of variation in a single stock, are ques- 
tions I can throw no light upon. 

Species of tropical Asia, West Indies, etc. 

Tropical countries have a few species of (J&cilioides of two 
groups: (1) the group of C. iota, comprising very minute species 
1.6 to 2.5 mm. long, markedly cylindric, with the whorls nearly 
flat. All are American. (2) the group of C. gundlachi, with 
the shell larger, usually 3 to 5 mm., composed of convex, very 
obliquely coiled whorls. The columella is only quite obsoletely 
truncate. These groups are known as Caecilianopsis and

The type lot at Amherst consists of three specimens. It is a 


gubcylindric shell, obtuse at both ends, of scarcely four whorls 
in most examples, 4J in the longest. The shell is clear corneous 
when fresh, showing the internal walls through, but it weathers 
to milky white. The whorls are only slightly convex, and are 
separated by a moderately impressed suture, margined below. 
The suture is at first nearly horizontal, but at the last 1 or 
2 whorls it descends rapidly, the width of the whorl progres- 
sively increasing. The aperture is acuminate above. Outer lip 
arches very strongly forward. The columella is more or less 
concave below, and is rather abruptly truncate above the base. 
Columellar callus usually moderate, but variable in thickness. 
Under a high power, an extremely minute spiral striation may 
be seen near the base. Measurements are as follows:

C. iota has been found only in Jamaica. It is readily dis- 
tinguished from other tropical- American species by its much 
narrower contour. Exact measurements which I have made of 
a large number of specimens from several localities show the 
difference in shape to be constant. 

Pfeiffer's figure of this species in the Oonchylien Cabinet is very 
poor. It shows no columellar truncation, and hence 0. iota 
was classed by Crosse and others in Geostilbia. Adams's type 
specimens, as well as numerous examples before me, have a 
distinctly truncate columella.

This species is closely related to C. iota, from which it differs 
by the stouter, more robust figure, specimens of the same length 
being invariably wider than iota. The general shape is slightly 
tapering cylindric, very obtuse at the ends. The whorls in- 
crease a little more regularly than in iota, the last turn of the 
suture being less oblique, though descending faster than the 
preceding one. This acceleration of the rate of descent changes 
the appearance of the shell and the proportionate size of aperture 
to total length with age, so that the addition of a whorl or even 
less alters the contour remarkably. The surface is lightly 
marked with growth-wrinkles and minute engraved spiral lines, 
visible only under a compound microscope. The columellar 
truncation is distinct, but rather weak in some examples. Two 
specimens from a lot taken by Gundlach are figured. 

PI. 5, fig. 82: length 2.4, diam. 0.8 mm. 

PI. 5, fig. 81: length 1.9, diam. 0.7 mm. 

The former of these examples corresponds to the type of 
A. pygmaa Pfr. ; the latter, a younger shell, agrees with Orbigny's 
type of A. consobrina. In my opinion these two names apply 
to one and the same species, in slightly different stages of 
growth. Pfeiffer's description of A. pygmaa follows. 

" A. pygmaaPh. Shell cylindric, smooth, pellucid hyaline, 
the apex rather obtuse. Whorls 5, rather flattened, separated 
by an oblique, lightly impressed suture, the last f the total 
length. Columella nearly straight, forming an angle with the 
belly of the preceding whorl, subtruncate at the base of the 
oval-elliptical aperture; peristome acute, the right margin 
dilated forward. Length 2.25, diam. f mm.; aperture f mm. 
long." (Pfr.) 

Var. veracruzenm (Crosse & Fisher). PI. 5, figs. 76, 77, 78, 
79. In this form the microscopic spiral striation is more dis- 
tinctly developed than in consobrina, visible from the suture to 
the base, the striae appearing crimped or waved (fig. 79). 
There is no other difference. Specimens measure:

The figures represent an older (fig. 76) and a younger (fig.

,(figs. 78, 79) from Tampico, representing the absolutely synony- 
mous form I called C. jod. 

In recognizing the Mexican specimens as a race distinguish- 
able from the Cuban form, I am probably placing too much 
dependence upon a slight variation in microscopic sculpture. 
I merely give the facts observed for what they may be worth.

Crosse has very inadequately figured minutissima, and I have 
copied his figure, pi. 5, fig. 80. Figure 84, pi. 5, and fig. 68 of 
pi. 4, represent what I take to be Guppy's species from 
Barbados. The general form is as described for pygmaa-, but 
the surface is smoother than in Cuban or Mexican shells, spiral 
lines being scarcely visible under the compound microscope 
except at the base. The columellar truncation is rather weak. 
Two specimens measure: Length 2.05, diam. .7 mm., whorls 5. 
Length 2.15, diam. .8, aperture 9 mm.; whorls 5. 

With these specimens were others resembling them except 
that the columella is very strongly truncate at the base (pi. 5, 
figs. 83, 85) at all stages of growth. These may represent 
another species, yet I am unable to satisfactorily separate the 
series. The two examples figured measure: length 2, diam. .7 
mm. (fig. 83); length 2.3, diam. .75 mm., whorls 5J (fig. 85) , 

Geostilbia mazei seems to me to be identical with minutmima.

The shell is similar to Catdlioides except in having the colum-

only by a slight sinuation, not an abrupt truncation. Type

The number of valid species of this group is uncertain, but 
several of them surely stand close to C. gundlachi. C. baldivinij

Pfeiffer's description of this shell is not very good. It tapers 
regularly to the very obtuse, rounded apex. There are 5 whorls, 
very obliquely coiled, quite convex, and parted by impressed 
sutures. The last whorl is evenly convex. The aperture is 
ovate, effuse at the base; the outer lip arches forward strongly 
in the middle. The columella is a little concave, and near the 
base is obsoletely truncate. It has a rather heavy callus in 
most fully adult shells, which passes up over part of the parietal 
wall. The color is pale corneous-brown, or sometimes almost 
clear corneous. There is no spiral striation. Two Cuban exam- 
ples figured measure: Length 4.2, diam. 1.25 mm. Length 
3.85, diam. 1.1, apert 1.3 mm. The figures do not well show 
the heavy callus upon the colunella and lower part of the parietal 

This is a somewhat common and widely distributed species, 
probably to be found throughout the Antilles. It was taken 
many years ago in Princeton, N. J., no doubt imported with 
West Indian plants. These specimens were reported as C. 
aricula in Binney' s "Manual." It occurred also in St. Helena, 
though whether it still survives there is unknown. 

The New Caledonian Geostilbia caledonica is in all probability 
the same species, a colony having been derived from Guadaloupe 
or some other Antillean source. At all events I am quite 


unable to see any difference in the shell. The original descrip- 
tion follows. 

G. caledonica: PI. 4, figs. 58, 59, 62.. " Shell imperf orate, 
fusiform-cylindric, thin, polished, diaphanous, clear-corneous. 
Apex abruptly rounded, very obtuse; suture hair-marginate; 
whorls 4, slightly convex, the last slowly descending, slightly 
more than half the total length. Aperture long-pirif orm ; peris- 
tome simple, unexpanded, thin, not acute, slightly thickened, 
the margins joined by a very thin callus; columellar margin 
having a longitudinal, small, diaphanous, glossy internal lamina 
giving the appearance of a basal truncation, not reaching the 
base. Basal margin broadly rounded; right margin arching 
forward. Length 3.5, diam. 1 mm." (Crosse). 

New Caledonia: Noumea, common in gardens, living in damp 
places under dead leaves, old wood and on the ground (E. Marie). 

Geostilbia caledonica CROSSE, Journ. de Conchyl. xv, 1867, p.

Two specimens from Noumea are drawn in figures 58, 59, 62, 
pi. 4. They measure 3. 7 x 1.2 mm., and 3.1 x 1 mm. 

Macrospira aperta Guilding has never been described. Too 
poor and dissimilar outline figures were given with this name 
by Swainson, without locality, dimensions, or any other par- 
ticulars. In 1892 Mr. E. A. Smith stated that A. gundlachi 
and veru were equivalent to aperta] and in 1895 he identified 
Geostilbia caledonica Crosse as a synonym of Megaspira (sic) 
aperta, from the comparison of specimens in the British Museum. 
In my opinion, M, aperta was not sufficiently defined by 
Swainson to be recognized. Its identity with C. gundlachi rests 
upon Mr. Smith's identification of specimens from Guilding, 
the locality of which is surmised to be the West Indies, but ie 
not positively known. No description of even these specimens 
has appeared, and Swainson' s figures are extremely crude. 

41. C. BALDWINI Ancey. 

Shell imperforate, very thin, whitish-hyaline or slightly cor- 
neous, diaphanous, glossy, polished; apex large, obtuse; spire 


Blender, subcylindric but tapering. Whorls 4, regularly in- 
creasing, separated by a very oblique, impressed suture mar- 
gined with a pellucid line; last whorl oblong, larger. Aperture 
piriform, the right margin arching forward; peristome simple, 
acute, scarcely thickened, the margins joined by a rather opaque 
callus. Columella somewhat callous, very slightly truncate 
above the base. Basal margin rounded. Length 3.75, diam. 1, 
aperture alt. 1 mm. (Ancey). 

Hawaiian Is.: Manoa, Oahu (Baldwin).

Specimens of presumably this species are in the Bishop 
Museum at Honolulu from the following places: Rocky Hill, 
Honolulu; Kanaohe, Oahu; Mana, Hawaii. I have no exam- 
ples at hand, but so far as the description goes there seems to 
be no difference between this species and C. gundlachi. 

42. C. BALANUS ('Benson' Reeve). PI. 4, figs. 60, (61?) 

Shell cylindrically oblong, somewhat fusiform; whorls 4, 
smooth, shining; apex obtuse; columella arched, truncated; 
aperture small. Dull white. (Reeve). 

Shell almost cylindric-aciculate, smooth, glassy-clear. Spire 
almost cylindric, slightly tapering above, with an obtuse apex; 
suture very little impressed. Whorls 4, rapidly increasing, the 
last forming two-fifths the total length, dilated basally. Colu- 
mella rather straightly receding, scarcely noticeably truncate at 
the base of the broadly angular-ovate aperture. Peristome 
simple, unexpanded, acute. Length 3, diam. hardly 1 mm.

I have not seen this species, which seems to be rather common 
in the higher, dry parts of India, and to be known chiefly by 
river-drift specimens. Pfeiffer's description and the figures of 
Reeve and Pfeiffer indicate a shell with only weakly-truncate 
columella, so that one understands why Colonel Beddome should 
compare Geostilbia caledonica, (which he states is identical with 
Indian specimens from North Canara, see Blanford, I. c.). 
Nevill also refers the species to Geostilbia. In his description of 
C. isseli, Paladilhe mentions emphatically its truncate columella; 
yet his figure seems to represent a Geostilbia very close to balanus. 
Blanford has stated that isseli is identical with balanus', but so 
far as I can judge from the literature, there are two species 
involved. Fig. 60 is copied from Reeve's type figure. I have 
also copied the figure given in Oonchologia Indica, pi. 4, fig. 61. 
By its strongly truncate columella, this figure seems to cor- 
respond with the description of C. isseli. 

43. C. MAURITIANA (H. Adams). PI. 4, fig. 69. 

Shell imperforate, subulate-cylindric, thin, hyaline, glossy, 
spire subcylindric, the apex very obtuse, suture impressed. 
Whorls 5, rather flattened, the last dilated at the base; columella 
arcuate, slightly truncate. Aperture acuminate-oval; peristome 
simple, unexpanded, acute. Length 4, diam 1, aperture 1.33

This does not seem to differ materially from gundlachi. 

44. C. COMORENSIS (Morelet). PI. 4, fig. 63. 

Shell imperforate, turrite, thin, hyaline, smooth; spire long, 
the apex rounded, obtuse. Whorls 6, plano-convex, subscalar, 


with a well -impressed suture, the last whorl one-third the total 
length. Aperture piriform, the outer margin simple, unex-

an angle with the basal margin. Length 4, diam. 1.25 mm.

Differs from G. mariei by its more slender shape, with longer 
spire of two more whorls, and a shorter aperture. 

45. C. MARIEI (Crosse). PI. 4, figs. 65, 66. 

Shell irnperforate, subcylindric, thin, polished, diaphanous, 
hyaline, whitish. Spire rather long, the apex abruptly rounded, 
very obtuse; suture impressed. Whorls scarcely 4, nearly flat, 
slightly convex, the last very little descending, shorter than the 
spire. Aperture regularly elongate-piriform, colored within 
like the outside. Peristome simple, whitish, the margins joined 
by a thin callus. Columellar margin somewhat thickened, 
having an appearance of truncation, hardly reaching to the 
base; basal margin rounded; outer arched forward, subacute. 
Length 3, diam. 1 mm. (Crosse).

46. C. STUHLMANNI (Martens). PI. 4, fig. 70. 
Imperforate, elongate, finely and regularly striate, translu- 
cent, yellowish -vitreous; 5 whorls, the first globular, smooth, 
the following rapidly increasing, rather flat, with deep, some- 
what step-like suture, which is more oblique between the penult, 
and last whorls. Aperture rather oblique; outer margin ap- 
proaching rectilinear, thin, simple; lower margin broadly 
rounded. Columellar margin thick, white, obliquely truncate 


at the base, continued above in a callous layer on the parietal 
wall. Length 9, diam. 3.66; aperture 4x2 mm. (Martens').

Described from one example. The figures, drawn by Dr. 
Boettger, show a distinctly truncate columella. This char- 
acter and the broad sutural margin seem to differ from the 
following species. 

49. C. MOELLENDORFFI n. sp. PI. 15, figs. 4, 5. 

The shell is clear corneous, glossy, marked with faint 
growth-lines and under a high power some faint traces of 
spiral striation are visible in places. The spire tapers regu- 
larly to the obtuse summit. Slightly over 4 whorls, convex 
and rapidly enlarging. Suture narrowly margined. The 
aperture is ovate; columella straightened below, not in the 
least truncate and not calloused. The outer lip is strongly 
arched forward. Length 4, diam. 1.4, length aperture 
1.55 mm. 

Philippines: Mananga, Zebu (Quadras coll.) 
The spire tapers much more than in C. gundlachi, the last 
whorl being wider, and the aperture is larger. The sutural 
margin is narrower than in C. gundlachi. In the type lot 
the columella is not calloused. C. philippinensis is a larger 
shell with proportionally smaller aperture. I have not been 
able to compare specimens of C. mariei and C. balanm. 

Genus GLESSULA von Martens. 

Glessula MARTS, in Albers, Die Hdiceen, edit. 2, 1860, p. 
254, type Achatina gemma Bens. BEDDOME, Proceedings of the 
Malacological Society of London, vii, Sept, 1906, pp. 160-172.- 
Electra ALBERS, Die Hel., 1850, p. 194, for Achatina ceylanica 
Pfr. Not Electra Lamouroux, 1816, not Electra Steph., 1829. 

The shell is imperforate ovate-conic or turrite, brown or 
corneous-brown, glossy and usually without strong sculpture; 
apex obtuse. Aperture irregularly oval; outer lip unexpanded, 
acute or blunt; columella short, more or less deeply concave, 
abruptly truncate at the base. 

Sole without distinct median area; no pedal margin; an outer 
mantle lobe on the left side. Kidney very long, band-like. 


Genitalia peculiar (pi. 15, figs. 2); there is a feather-like 
gland (fig. 3) where the vas deferens enters the penis. The 
latter contains a short conic, perforated papilla and two of 
longitudinal folds. The prostate gland of the hermaphrodite 
duct consists of entirely separated narrow follicles, as in 
Achatina. The spermatheca has a short duct. Uterus contain- 
ing several large shells with fully 2 whorls. 

The jaw is very finely striate, almost smooth. Radula has 
ahout 110 teeth in a transverse row. The central tooth is very 
small, tricuspid; laterals with three cusps; outer marginal teeth 
very finely 3- or 4-cusped ( G. orophila from Madras, according 
to Semper). 

Type G. gemma Bens. Distribution, Oriental and Ethiopian 

Glessula was associated with " Oionetta" (that is, the Ferus- 
sacida as herein understood) by Professor von Martens in 1860. 
Various other authors, both before and since, have thought the 
group Achatinoid, belonging to ' * Stenogyra " in the former 
wide limits of that term. We know too little of its anatomy to 
give a definite opinion, but the presence of a glandular append- 
age (appendix or flagellum) at the end of the penis is a feature 
unlike any Achatinida. The homology of this appendage is not 
certain, however. The position of the ureter is unknown. I 
have been unable to obtain alcoholic material necessary for an 
investigation of the relations of Glessula to Subulina, Homorus, 
Bacillum and Pseudoglessula. 

In most (but perhaps not all) species, the lip becomes 
slightly blunt and smooth in fully adult shells, thereby differing 
from Subulina, which has an acute lip at all stages or growth. 

In G. orophila, Semper found in the uterus 4 large embryos 
with shells having fully two whorls, and a small one with a 
half whorl and very large caudal vesicle. Various other species 
have been found to be viviparous, while others bring forth 
globular eggs like those of Subulina. Like that genus, also, the 
Glessulse reproduce before attaining full size. 

Glessula has been studied mainly by specialists on the Indian 
fauna. Benson, W. T. Blanford, Beddome and Godwin- 
Austen have chietiv contributed to thf literature. Blanford's 


"Contributions to Indian Malacology," continued through 
many years of the Journal of the Asiatic Society of Bengal, 
contain a great mass of information on this genus, as on many 
others of the Indian fauna. Hanley and Theobald illustrated 
most of the types of Benson, among others, in their Conchologia 
Indim. Finally, Colonel R. H. Beddome has recently reviewed 
the genus in his "Notes on Indian and Ceylonese Species of 

From the purely conchological standpoint we may be said to 
have an extensive knowledge of Glessula, yet various characters 
of the first importance have been neglected. The embryonic 
whorls of the types must all be re-examined and their sculpture de- 
scribed. Our ignorance of the embryonic sculpture of many 
forms prevents any natural classification of the species. The 
surface of the later whorls in all the species should be examined 
under high power, since some species have a minute sculpture 
not visible with an ordinary hand lens. 

No fossil species of Glessula are known to me. A few species 
of other genera have been referred to Glessula. 

Glessula obtusa and G. erosa Blanford are species of Bacillum 
(Vol. xvii, pp. 1, 4). 

Glessula orthoceras G.-A. is a Bacillum (I. c., p. 2). 

Glessula philippinensis Semper, of Cooke, is a Cezcilioides (this 
vol., p. 49). 

No natural classification of the species of Glessula can be 
attempted until the sculpture of the apices of the shells and the 
anatomy of a number of representative species are studied. I 
have separated a group of West African forms (species 89 to 
92) as a new section, Neoglessula. The species are here grouped 
geographically, as follows: 

I. Ceylon, species 1 to 13, 34, 49, 52. 
II. Peninsular India, species 14 to 58. 

III. Extra-Peninsular India, Indo-China, Yunnan, etc., 

species 59 to 77. 

IV. Habitat unknown, species 78 to 80. 

V. Sumatra, Java and Borneo, species 81, 82. 
VI. Eastern Africa, species 83 to 86. 
VII. West Africa, species 87 to 92. 



The Ceylonese Glessulse are closely related to those of southern 
India, and in a few cases seem to be of identical species. Such 
cases should receive very careful comparison. The following 
forms, described from Peninsular India, have been identified by 
reliable authorities from Ceylon.

Shell turrite-oblong, solid, closely striate; pale tawny, varie- 
gated with darker streaks; nearly lusterless, having a woody 
appearance. Spire turrite, the apex rather obtuse, suture lightly 
impressed, very closely crenulated. Whorls 7 J, rather flattened, 
the last nearly equal to two-fifths the total length, the base 
slightly compressed and smoother. Columella very deeply 
arcuate, white-calloused, obliquely, abruptly truncate. Aper- 
ture sinuous-semioval, white within. Peristome simple, obtuse, 
the right margin spreading. Length 28, diam. 11, aperture

BEDDOME, P. Mai. Soc. vii, 164, with var. minor. 

The first 2-J whorls seem to be nearly smooth, but with a 
finely crenulate suture; then fine, distinct striae begin, strongest 
near the suture, weaker below. On the spire these striae are 
separated into groups by occasional deeper grooves or larger 
stria?; and more or less trace of such irregularity may often be 
traced on the last whorl. Under the compound microscope, 
the surface is seen to be very densely covered with minute granules 
arranged in spiral lines (pi. 6, fig. 16). These give it a charac- 
teristic silky sheen, unlike the smooth species. Specimens 
before me measure as follows, all being adults with the lip blunt. 


Length 29, diam. 13, aperture 12 mm. ; whorls 8. 

Length 28, diam. 11.5, aperture 11.7 inm. ; whorls 8. 

Length 24, diam. 11.7, aperture 10.5 mm.; whorls 7J. 

The color is yellow or olivaceous, with some reddish streaks. 
The interior is pale lilac or flesh-colored. 

This is one of the most distinct species of the genus. Col. 
Beddome has mentioned a " var. minor, length 18 to 20 mm." 

Pfeiffer has described and figured a variety which is u more 
distinctly striate, silky, brownish-tawny " (pi. 6, fig. 17). 
This form is thought by Col. Beddome to be G. beddomei Blanf. 

2, G. LANKANA Pilsbry, n. sp. PI. 7, figs. 1, 2, 3. 

Shell oblong-turrite, thin but rather solid, yellow or tawuy, 
with some narrow darker or chestnut streaks on the spire. 
Surface very glossy, finely and deeply striate, the strise unequal, 
in places being as narrow as the intervals, but occasionally much 
wider. Under the compound microscope a very faint spiral 
striation is visible, the spirals being very weakly beaded in 
places. The first 2 whorls are smooth. Spire conic with 
straight sides and' obtuse apex. Suture irregularly crenulate. 
Aperture vertical, flesh-tinted inside. Outer lip obtuse, form- 
ing a regular arch. Columella moderately concave, obliquely 
truncate at base. 

Length 27.2, diam. 11, length apart. 10 mm.; whorls 8J. 

Length 27, diam. 11.2, length apart. 10.5 mm.; whorls 8J. 

Ceylon: Matella District (Layard). 

Closely related to G. inornata, but more glossy and having 
much less distinct microscopic granulation, as may be seen by 
comparing fig. 3 with pi. 6, fig. 16. The outlines of the spire 
are straighter; there are more whorls in the same length, and 
the aperture is smaller. G. beddomei has a more prominent 
and more deeply truncate columella. 

3. G. PARABILIS (Benson). PI. 7, fig. 4. 

Shell oblong-ovate, rather solid, glossy, rugose-striate, decus- 
sated with most minute, obsolete spiral striae, whitish under a 
buff-corneous cuticle. Spire long-conic, the apex obtuse, suture 
lightly impressed, subcrenulate. Whorls 6, subplanulate, the 
last a little convex, scarcely three-sevenths the shell's length. 


Aperture triangularly semiovate, whitish inside. 
slightly inflexed, the margins joined by a thin callus; right 
margin sinuous, slightly obtuse, columellar margin very deeply 
arcuate, strongly truncate obliquely. Length 20, diam. 10, 
aperture 9x5 mm. (Bens.).

tuse. Whorls 7, convex, the last scarcely one-third the total 
length, obsoletely angular at the periphery. Aperture slightly

smooth. The sides of the spire are very slightly convex; 
but the whorls are strongly convex, parted by a very dis- 
tinctly crenulated suture. The aperture is small; columella 
very deeply excavated above. Length 17, diam. 7.8, aper- 
ture 6.8 mm. ; whorls 7%. Nalande, Ceylon. 

Var. PUNCTOGALLANA (Pfeiffer). PI. 6, figs. 3, 4, 5. 

Shell oblong-ovate, slightly striatulate, glabrous, glossy, 
pellucid, corneous-tawny. Spire pyramidal, the apex obtuse. 
Whorls 7%, convex, the last about two-fifths the total length, 
base rounded. Columella very deeply arcuate, reaching far 
forward, abruptly truncate. Aperture vertical, subtriangu- 
lar-semioval ; peristome simple, the right margin regularly 
arcuate. Length 16, diam. 8, aperture 7x4 mm. (Pfr.).

"Differs from A. ceylanica by the smoother, more glossy 
shell, with longer spire, shorter last whorl, and the columella 
arched forward more " (Pfr.). The whorls are much more 
convex in punctogallana than Pfeiffer 's description and fig- 
ures indicate in ceylanica. The largest shell before me (fig. 
5) measures, length 17.5, diam. 8.4, aperture 7 mm., whorla 
nearly 8. Others from the Matelle district, received from 
Layard, are typical in size. Both lots were received as 

This form differs from G. nitens by its stouter, more com-

6. G. CEYLANICA (Pfeiffer). PL 6, figs. 7, 8. 

Shell ovate-oblong, striatulate, silky, thin, tawny-corneous; 
spire pyramidal, the apex obtuse. Whorls 7, a little convex, 
the last three-sevenths the total length, inflated. Columella 
short, arcuate, abruptly truncate. Aperture rather wide, 
semioval; peristome thin, acute. Length 16, diam. 8, aper-

Closely related G. nitens, but the description and figure 
indicate that the whorls are much less convex in ceylanica. 
Colonel Beddome records specimens of ceylanica 30 x 14 mm. ; 
but their specific identity may possibly be doubtful. 

7. G. DESHAYESI (Pfeiffer). PL 6, figs. 6, 12, 13. 

Shell turrite-ovate, rather thin, nearly smooth, glossy, 
corneous-brown; spire long, convex, the apex rather obtuse, 
suture simple, rather deep. Whorls 7, convex, the last two- 
fifths the length, rounded at base. Columella somewhat 
twisted, broadly and obliquely truncate. Aperture slightly 
oblique, rhombic-semioval ; peristome simple, obtuse, the right 
margin somewhat spreading. Length 11, diam. 5, aperture

Smaller than G. nitens, and of a richer brown color, but 
otherwise it is closely related. The whorls are strongly con- 
vex and the surface very brilliant. Some of the upper post- 
embryonic whorls are rather distinctly striate. The suture 
is much less distinctly crenulated than in G. nitens, nearly 


simple. The sides of the spire are slightly convex. Fig. 6 
represents a typical example, length 11, diam. 5.2, aperture 
4.5 mm., whorls 6%. The lip is "finished." 

Two specimens, the longest and shortest from another lot 
of 15, are drawn, pi. 6, figs. 12, 13. Neither has the lip 
"finished," though no doubt both are nearly mature. They 
measure as follows.

Shell ovate-oblong, striatulate, under a lens decussated 
with obsolete, close, spiral very fine striae; glossy, brownish- 
corneous, translucent; spire lengthened, subconic, apex ob- 
tuse, suture lightly impressed. Whorls 6, a trifle convex, 
the last scarcely two-fifths the total length. Aperture ver- 
tical, oblong-ovate; peristome whitish-bordered within; colu- 
mella exceedingly deeply arcuate, basal margin thickened.

"This little species of a group which has so many rep- 
resentatives in Ceylon, the Nilgherries, and the damp woody 
mountains of the North-eastern India, with a more slender 
form than A. oreas nobis, is well distinguished from the 
allied forms by its peculiar sculpture under the lens, and by 
the internal incrassation of the peristome, a feature which 
is also observable in the species A. crassilabris nobis. from 
north-eastern India." (Benson.) 

This species has not been figured. With the same dimen- 
sions as G. deshayesi, it seems to differ by having the whorls 
only very little convex, whilst in deshayesi they are strongly 

8fl. Var. taprobanica Pils., subsp. n. PI. 7, fig. 16. 

Shell smaller, very pale yellow. Sculpture of fine vertical 


grooves, close on the spire but rather widely, unevenly spaced 
on the last two whorls ; no perceptible spiral lines ; two 
whorls at the summit smooth. Aperture small, the outer lip 
rather thick ; columella moderately concave, sub vertically and 
not very deeply truncate at the base. 

Length 8.5 to 8.8, diam. 3.2, aperture 3 mm. ; whorls 6!/2- 

Ceylon: Kandookerre (E. L. Layard). 

This form was distributed by Layard as pachycheilus Bens. 
That species has not been figured, but according to the de- 
scription it differs from this in several respects. G. colletta 
is a more slender, darker species, with a. less thickened lip. 

9. G. SERENA (Benson). PI. 6, fig. 9. 

Shell ovate-pyramidal, rather solid, very highly polished, 
slightly, obsoletely striate, tawny corneous, pellucid. Spire 
elongate, subturrite, the apex abruptly obtuse ; suture im- 
pressed, submarginate, crenulate. Whorls 6% to 7, subcon- 
vex, convex above near the suture, the last whorl slightly 
compressed at the base. Aperture vertical, three-sevenths the 
total length, subtriangular-ovate; peristome unexpanded, 
rather obtuse; columellar margin very deeply arcuate, whit- 
ish-calloused, at the base abruptly and obliquely truncate. 
Length 20 to 21, diam. 9 to 9.5, aperture 9 x 5.5 mm. (Bens.)

pi. 78, 1 8. 

This species is very close to G. nitens, but the whorls are 
less convex. It is doubtfully distinct from G. ceylanica, but 
from the figures, that seems to be more straightly conic and 

10. G. LAYARDI Pilsbry, n. sp. PI. 7, figs. 6, 7. 

The shell is oblong-turrite, yellow-corneous with profusely 
scattered whitish dots and spots (produced by disintegration 
of the surface), paler towards the summit. Surface very 
glossy, without noticeable microscopic sculpture, but marked 
with unevenly spaced grooves, which are rather weaker on 


the last whorl, and obsolete on the base. The summit is ob- 
tuse, rounded, first whorls smooth. Whorls 6%, moderately 
convex. Suture elegantly but somewhat irregularly denti- 
culate. Aperture vertical; outer lip obtuse; columella very 
short, moderately or deeply concave, subhorizontally and 
very deeply truncate. Length 14, diam. 6, length of aper- 
ture 5.9 mm. Length 13.5, diam. 6.1, length of aperture 
5.9 mm. 

Ceylon (Layard). 

This species differs from G. ceylanica by its very much less 
deeply concave columella. It is a smaller and more slender 
shell than G. serena, which seems to be its nearest ally. The 
denticulation of the suture is a prominent feature. Though 
"live" shells, the surface is eroded in places. The whitish 
flecks probably will not be found on shells from stations 
where they are less liable to erosion. 

11. G. VERUINA (Benson). 

Shell cylindric-turrite, very much lengthened, dirty whit- 
ish, unevenly striate; the spire gradually tapering above; 
suture impressed, crenulate ; apex obtuse. Whorls 12^ to 13, 
narrow, cylindric, the last scarcely two-elevenths the total 
length. Aperture vertical, truncate-oval; peristome unex- 
panded, acute; columella slightly arcuate. Length 25, diam. 
5 mm. (Bens.)

12. G. COLLETT.E Sykes. PL 7, fig. 13. 

Shell elongate, thin, smooth, obscurely longitudinally 
striated, brown or brown -corneous, the apex rather obtuse; 
suture impressed. Whorls 6 to 6%, a little convex, the last 
half the length of the shell. Aperture nearly vertical, lunate- 
oval, columellar margin callous, paler, obliquely truncate. 
Length 8, diam. 2.8 mm. (Sykes). 


Ceylon: Ambagamuwa (Mrs. Collett). 

Glessula colletta SYKES, Proc. Malac. Soc. Lond. iii, July,

Topotypes before me are rather dark yellowish chestnut 
colored, with sculpture of impressed vertical grooves. These 
are rather widely separated on the later whorls, but close 
above. Nearly two whorls at the summit are smooth. Length 
8, diam. 2. 9, aperture 2.9 mm. long, whorls 6%. 

Compared with G. p. taprobanica, this is a more slender 
shell, hence the whorls appear longer, and they are more 
evenly convex, the suture being less narrowly impressed. 

13. G. SIMONI Jousseaume. PI. 7, fig. 8. 

Shell small, ovate, thin, costulate, glossy, pellucid, fulvous- 
corneous. Spire conoid, the apex rather obtuse, suture im- 
pressed. Whorls 5 to 6, convex, the last half the total 
length, slightly tapering at the base, rounded. Aperture ver- 
tical, semioval; peristome unexpanded, thin, acute; the right 
margin less arcuate; columella callous, nearly straight, very 
deeply arcuate, obliquely truncate, at the umbilical region 
appressed and depressed. Diam. 3 mm., alt. 1.5 mm. (Jouss.)

This minute form has about the size of a Tornatellina, but 
seems to be more strongly sculptured than is usual in that 
genus. The embryonic whorls are smooth, a little darker 
than the rest -of the shell. Four specimens were taken, two 
of them smaller than the type, which is thought by Jousseaume 
to be immature. 


14. G. SHIPLAYI (Pfeiffer). PI. 9, fig. 8. 

Shell turrite, smoothish, pellucid, glossy, corneous; spire 
regularly tapering, the apex obtuse ; suture substriate ; whorls 
13, convex, the last slightly more than one-third the total 
length, rounded, more distinctly striate; columella somewhat 
straightly running forward, at the base rather widely trun- 


cate. Aperture a little oblique, rounded-oval; peristome un- 
expanded, very thin. Length 25.5, diam. 6.3 mm., aperture 
5.5x3.25 mm. (Pfr.).

''Full grown specimens were very rarely found by me, 
though young half- and three-quarter grown ones are most 
abundant on the Nilgiris. This and some other species cer- 
tainly breed before the shell attains full size or a hardened 
peristome, as I have taken eggs from such shells. The peris- 
tome differs much in mature specimens, sometimes being very 
thick and solid, sometimes quite thin, but, even then, firm, and 
not breaking or becoming jagged at the touch, which is the 
sign that the shell has not finished its growth. Full-grown 
examples of shiplayi are very like tenuispira, but smaller. It 
also runs nilgirica very closely, but the latter has a stronger 
sculpture, and is broader at the base." (Bedd.)

Shell subcylindrkj-turrite, thin, pale corneous, translucent,

part, the sides convex towards the obtuse apex; suture im- 
pressed. Whorls 9 to 101/2, convex, regularly increasing, the 
last short, about one-fourth to one-fifth the total length. 
Aperture ovate-oblong, a little oblique; peristome thin; colu-

' ' The nearest ally to this species appears to be O. tamulica 
(W. & H. Blanf.) from near Trichinopoly, which is distin- 
guished by greater diameter in proportion to the length, and 
a more regularly tapering spire. Intermediate forms may 
hereafter be found however. 

"A specimen from the Shevroy hills near Salem in south- 
ern India, sent to me by Major Beddome, only differs from 
O. hebes in being longer and slightly more attenuate towards 
the apex. It has 13 whorls." (Blanf.) 

"Ten specimens received from Blanf ord and E vizard, col- 
lected near Poona, are all young, with quite unformed lip; 
and all the types of hebes in Blanf ord 's collection, and the 
specimens in the Natural History Museum and others that I 
have seen, are the same. If full-grown, or nearly so, it 
must be a much smaller species than shiplayi. It runs the 
young of that species rather closely, but the apex is gener- 
ally blunter. Specimens collected by me on the Shevaroys 
are referred here by Blanford ; they are, however, immature 
and appear rather to belong to fairbanki, if that species is 
distinct, which I doubt. When collected I took them to be 
young of shiplayi. Until hebes and fairbanki are found with 
mature lips, they must, I think, remain doubtful species. 

"Hanley's figure of hebes has the tapering apex of young 
shiplayi and is unlike my type of hebes." (Beddome.) 

16. G. FAIRBANKI (Benson). PL 9, fig. 7. 

Shell subcylindric-turrite, striatulate, obsoletely and very 
minutely spirally decussate, polished, translucent, buff- 
corneous, the spire having subconvex sides towards the apex, 
summit obtuse; suture distinctly impressed; whorls 8, sub- 
convex, short, the last four slowly increasing in diameter; 
last whorl rounded below, one-fourth the total length; aper- 
ture suboblique, ovate, angular above and below, the margins 
joined by a callus; columella lightly arcuate, obliquely trun- 
cate; basal and outer margins thin. Length 12, diam. 4, 
aperture 3 x 2.5 mm. (Bens.).

"The nearest Nilgiri form is A. corrosula Pfr. The more

safely distinguished it " (Bens.). 

Col. Beddome considers fairbanki doubtfully distinct from 
G. hebes. Both were based upon shells not fully mature.

Whorls 11, convex, short, the upper ones rib-striate, last 
whorl rounded below, scarcely one-fourth the total length. 
Aperture slightly oblique, elliptical-ovate, margins joined 
by a callus, columellar margin slightly arcuate, whitish, ob-

Benson records a variety which is more inflated, ovate- 
turrite, 22 x 8 mm. No locality for it is mentioned. He 
writes : ' ' This shell has relations to A. chessoni in the attenu- 
ation of the spire towards the summit, a feature observable 
also in the northeastern A. tenuispira. It differs in form, 
size, proportions, etc. In one specimen from Bombay the 
attenuation of the spire is less conspicuous." Col. Beddome 
states that the specimens he has seen are in no way separable 
from tenuispira. 

The initial half whorl is smooth; then very fine, close, 
regular vertical striae appear, continuing to the end of the 
embryonic shell, which consists of two whorls (fig. 9). After 
this, the strise are irregular, coarse ones appearing in groups, 


or at somewhat irregular intervals. On the last two or three 
whorls the striation is still coarser, and chiefly on the upper 
part of each whorl, the lower part being much smoother. 
Specimens from Poona before me are more slender than those 
from Bombay, measuring 21 x 7 mm., with 10^2 whorls. 

The sculptured embryonic whorls show that this species is 
not related to G. tenuispira. I am much inclined to doubt 
that the specimens recorded from the Sylhet region are really 
notigena. They are probably tenuispira.

" My Travancore specimens were labelled subtornensis by 
Nevill, but I cannot see how they differ. I took a very beau- 
tiful, dark chocolate-colored variety on the Calcad Hills in 
Tinnevelly." Fig. 4 is the typical form from Torna Hills. A

" This is allied to the Nilgiri G. jerdoni Bens., but the sides 
of the spire are less convex, the shell being more regularly 
pyramidal, with a less obtuse apex. In some of the specimens 
of this species collected alive, but in which the animal had 
subsequently dried up, I found young shells. It would thus 
appear to be viviparous. I have observed the same circum- 
stance (the occurrence of young shells inside the old one) in 
G. cassiaca Bs. In other species of this genus I have found 
small round eggs with a calcareous shell, but these may be 
hatched, before they are deposited by the parent " (Blanf.).

The initial half whorl is smooth, the next two whorls closely, 
very regularly striate vertically. Then the coarser, post- 
embryonic sculpture begins (pi. 10, fig. 4). The striation is 
rather sharp but uneven, and the striae are strongest at and 
near the suture, decreasing downwards. It resembles G. noti- 
gena somewhat, but the early whorls are not attenuated, and 
there are 2y 2 embryonic whorls. 

Col. Beddome remarks : ' ' I found the smaller variety very 
abundant on the top of the Myhendra Hill ( Ganjam) . The 
larger variety, found near Calcutta and in central India, and 
well figured by Hanley, is a rare shell. It has a shorter and 
blunter apex and fewer whorls than G. vandalica, but speci- 
mens of that species sometimes do duty for it in collections. ' '

Reeve's second locality, Colombo, Ceylon, was probably due 
to an erroneous identification. Col. Beddome omits the Nil- 
giris from his list of localities. He writes: " My Golcondah 
specimens were labelled by H. Nevill G. subbrevis, but I can- 
not see how they differ. Nevill, I think, saw only young ex- 
amples. ' '

with the Bengal A. gemma, which is ordinarily of the same 
size, by its less rapidly-decreasing spire, solidity and color;

1 The nearest ally to this small species appears to be the 
Darjiling A. crassula B. Prom this it is mainly distinguished 
'by the shape of the spire which is more convex at the side, 
by its smaller breadth compared with its length, and by its 
more marked and slightly marginate sutures. 

" A. paupercula is probably common upon the Shevroys. 
All the specimens, however, found by Mr. King at that local- 
ity are bleached, two specimens from the Kolamullies alone 
retaining their original texture " (W. T. & H. F. Blanf ord).

"This shell resembles in form A. oreas Bens., but is dis-

stronger sculpture. Possibly the two varieties should be 
ranked apart, .as there is considerable difference between 
them. A third form, shorter and more tumid, occurs near 
Poona. As other intermediate varieties probably exist, I 
prefer for the present classing all in one species, but it may 
hereafter be desirable to distinguish them." (Blanf.)

"Full grown shells collected in the Teesta Valley near 
Darjiling, and in N. Canara, measure 44 mm. in length, and 
have 14 whorls" (Beddome). G. baculina and G. pertenuis 
are considered to be specifically inseparable from G. tenui- 
spira by Col. Beddome, a conclusion supported by the speci- 
mens before me. The presence of this trans-Gangetic snail 
in the North Canara Hills is remarkable, if indeed, the Canara 
shells are really of the same species.

denticulate. Aperture oblique, ovate-triangular; peristome 
simple, acute. Columella abruptly arcuate, obliquely pro- 
duced, vertically truncate at the base. Length 38, diam. 6.5 
to 7.5 mm.; aperture 7x4 mm. (Blanf.). 

Khersiong, Himalayas of Sikkim. 

''This species appears to have escaped the notice of all 
previous collectors in Sikkim ; it was found in association with 
its near ally G. tenuispira Bens., by Dr. Stoliczka during a 
recent visit. It is easily distinguished from the latter species 
by its slenderness, (the diameter being % of the length) 
and the comparative narrowness of the whorls; moreover by 
the form of the columella, the lower part of which is bent 
abruptly almost at right angles with the slope of the inner 
lip; while in G. tenuispira, G. erosa, and other allied forms, 
the curvature is at the utmost obtuse, Specimens, the shell 
of which has been slightly weathered, show fine spiral mark- 
ings, but these are not visible unless the shell has become 
somewhat opaque. The animal is dark leaden grey, some- 
what paler at the sides of the foot." (Blanf.) 

1 ' This is, I believe, only a more slender form of tenuispira, 
as I have specimens intermediate in breadth ; as to any differ- 
ence in the columella, some of my specimens of tenuispira 
have the lower part more bent than in any of the supposed 
baculina " (Beddome).

impressed, subcrenulate. Whorls 11-12, convex, the last 
about % the length of the spire. Aperture oblique, ovately

A much more slender species than A. tenuispira Bens., 
(a variety of which also abounds in parts of Pegu), though 
there are signs of a passage. The present appears to replace 
A. tenuispira in Arakan and Bassein. Mr. Benson, to whom 
I sent a specimen, observes that it is intermediate between 
A. tenuispira and A. hastula Bens. (Blanf.)

and Naga Hills; Burma, He remarks that " Blanf ord's 
types and all the specimens I have seen of this, are young 
shells, with fragile, unformed lips. They fit well with young 
of tenuispira. Blanford himself mentions that there are 
signs of a passage, and it would 'certainly not be advisable to 
consider it a good species without seeing specimens with adult 

60. G. NAJA 'Blanford' n.sp. PI. 12, fig. 10. 

Shell slender, turrite, thin, yellow-corneous, glossy, 
weekly striatulate, and having vertical grooves at unequal 
intervals; this sculpture is most evenly developed just below 
the suture. Under the compound microscope glimpses of ex- 
cessively weak close spiral granule-lines may be seen in places. 
Outlines of the spire nearly straight, a trifle contracted near 
the apex. Whorls 9 1 / 4, moderately convex, separated by a 
deeply impressed simple suture. Aperture a little oblique; 
outer lip thin; columella rather long, regularly concave, 
truncate at the base. Length 19, diam. 6.6, length of aper- 
ture 6.5 mm.

(Glessula) n. sp., NEVILL, Handlist Ind. Mus. p. 170, no. 80. 

The later whorls are decidedly longer than in G. tenuispira 
and its immediate allies. The specimens were received from 
Nevill under the name used above; they may possibly be 
Glessula no. 80 of his Handlist, since they seem related to 
G. subfusiformis. 

61. G. NILAGABICA ('Benson' Reeve). PI. 9, fig. 5. 

Shell pyramidally turrited; whorls 10, convex, very finely 


crenulated at the sutures, then striated; columella rather 
deeply arched; aperture small; brown-horny (Reeve).

Mr. G. Nevill has expressed the opinion that the form fig- 
ured by Reeve, which he had not seen, is distinct from 
G. perotteti (cf. J. A. S. B. 1881, xl. p. 136).

Length 30, diam. 9.5 mm., whorls 11. Distinguished from 
both St. nilagirica and St. perotteti, not only by its greater 
size and more numerous whorls, but especially by the 
(throughout) regular and prominent striation, not crenulate 
at the suture; from St. vadalica Blanford, which it perhaps 
even more closely resembles, in general aspect at any rate, 
by the more abruptly tapering apical whorls, more arched 
columella, &c. Nullaymullay Mountains, Kurnool District,

"This species is an elongate and larger form of Glessula 
crassilabris Bs., of which G. pyramis is a closer variety; but 
its much more elongate form and stronger striation make it 
a good connecting species with G. butleri described further on. 
The form from the Lukah Valley is a tumid departure from 
the type figured. Alt. 0.75, major diam. 0.38 inch. Alt. 
0.65, major diam. 0.35 inch.*' 

"I look on all these species as properly varieties, and 
G. crassilabris, very abundant in all the grass country of the 
Khasi Hills, may be taken as the type ; a difference in eleva- 
tion and condition of habitat, from damp dark forest to hot 
grassy slopes, having produced modifications of form." 
( Godwin- Austen. ) 

Figs. 15, 16, are copied from Godwin- Austen 's originals. 
A typical specimen, length 18.75, diam. 7.8, aperture 7.5 mm., 
whorls slightly over 7, is shown in figs. 13, 14. The em- 
bryonic whorls are closely and finely striate vertically, as in 
G. notigena; hence the species has no affinity to G. crassilabris. 
It is a much less robust shell than G. crassilabris, and less 
polished ; and on the last whorl there are traces of fine spiral 
striation, as shown in fig. 13. The sculpture of the later 
whorls is irregular; there seem to be unequally separated 
grooves, with finer striae and grooves in the intervals, but 
quite unequally developed. The suture is crenulate. On the 
last whorl or two s,ome traces of spiral strise appear, in places. 


The outer lip is a little sinuous, being retracted above; it is 
moderately thickened or obtuse. 

Col. Beddome considers this species identical with G. facula.

Length 18, diam. 8, aperture 7.5x4 mm,, whorls 8 (Pfr.). 

The shell is ovate-oblong, yellow. The embryonic whorls 
are smooth, a little over two. Subsequent sculpture consists 
of rather close grooves, most prominent at the suture, which is 
rather deeply impressed, though the whorls are only moder- 
ately convex. The suture descends a little near the lip. The 
aperture is rather small, outer lip decidedly obtuse, thick- 
ened, its rounded edge bicolored, white and yellow. The 
outer lip is slightly retracted in the upper part. Length 20.5, 
diam. 9.5 mm., whorls 6% (fig. 15).

Godwin- Austen (1875) considered pymmis, butleri and il- 
lustris as subspecies of G. crassilabris. The latter is de- 
cidedly more robust than illustris, which belong to a differ- 
ent group ; pyramis and butleri are both more elongate shells.

This species closely resembles Glessula peguensis Blanford, 
but is less convex, that is, more slender, and a thicker texture; 
it can also be easily distinguished by the characteristic, 
crowded, well-developed, nearly perpendicular, longitudinal 
striation, varying slightly in direction on each whorl, much 
as in many species of Pomatias. The columella also is 
peculiar. Type in Indian Museum, Calcutta." (Nevill.)

Two embryonic whorls are smooth, the last becoming 
crenulate below the suture. The following whorls are 
grooved at unequal intervals, the grooves strongest near the 
upper suture, weakening near the lower. The last whorl has 
rather close grooves and wrinkles. This sculpture is visible 
only under a lens. The columella is only moderately con- 
cave in specimens I have seen, and is very obliquely trun- 
cate. The outer lip is whitish, a little thickened and obtuse, 
as usual in adult Glessulas. A specimen from Muong-Lai 


measures, length 12.7, diam. 6, length of aperture 5 mm.; 
whorls 6% (fig. 7). 

Col. Beddome believes G. paviei to be a synonym of G. areas. 
I have been unable to compare specimens of the latter, but I 
think they will prove distinct.

11 The height of the visible part of the penultimate whorl 
somewhat exceeds its breadth (diameter), and has the pro- 
portion to the last whorl of 1 :!%. 

"This species is quite like some described by Benson from 


the mountainous region of India, and especially stands about 
midway between oreas and jerdoni, both from the Nilgiris. 
A similar species from Java is Hasselt r s Acicula cornea, fig- 
ured on his unpublished plate 14, fig. 5, from the mountain 
Salak." (Marts.) 

Prof. Boettger states that by the study of Mr. Rolle 's speci- 
mens of G. sumatrana, he sees that G. javanica is identical, 
and the latter name should be withdrawn. Apparently 
"javanica" is 'an error for cornea. The original account

It is the sole representative of the genus in Java, 'and stands 
nearest to G. sumatrana v. Marts., as von Martens has al- 


ready noted. G. sumatrana is however more tapering at the 
apex and base, and it has not the strong striation at the 
suture. Moreover the alt. of the visible part of the penult, 
whorl in the Javan species is nearly a half less than its

VII. West African species. 

Two quite distinct groups of Glessula are represented in 
West Africa. The group of G. lavigata, has substantially 
the shell-structure of Indian Glessulae. The shell is smooth 
throughout (species 87, 88) . In the group of G. paritura the 
post-embryonic whorls are finely rib-striate (species 89 to 92). 

Group of G. lavigata. 

The central teeth of G. lavigata are narrow, not half as 
wide as the adjacent laterals. There is a well developed 
but not overhanging cusp. The laterals are quadrate, tricus- 
pid, with overhanging cutting-points on all the cusps. Middle 
cusp longer than the basal plates. There are about 8 laterals, 
then one or two transitional teeth, followed by the marginals, 
also of the tricuspid type (pi. 15, fig. 9). The jaw (pi. 15, 
fig. 10) is very minutely plaited, serrate on the cutting edge, 
at least in places. 

87. G. LJEVIGATA (Pfeiffer). PL 14, figs. 9, 11, 12. 

Shell turrite-oblong, rather solid, smooth, buff- waxen ; spire 
elongated, the apex obtuse. Whorls 6, but slightly convex, 
the last about one-third the total length, rounded beneath, 
striolate anteriorly. Columella callous, somewhat twisted, 


obliquely truncate. Aperture oblique, acuminate-oval, pearly 
within; peristome simple, acute. Length 17, diam. 6 mm. 

Habitat unknown (Cuming coll.). High on the serra de 
Pedras de Guinga, under stones, at an elevation of 3000 ft., 
district of Pungo-Andongo, Angola (Welwitsch). "For- 
careach, Senegambia" (A. N. S. Coll.).

iv, 607 ; Novit. Conch, i, p. 32, no. 54, pi. 8, f . 6, 7. MORELET, 
Voy. Welwitsch, p. 77. Glessula lavigata, PFR., Nomencl. p. 
330. Homorus I, KOBELT, C. Cab. p. 110. 

Morelet, who was the first to record a locality for this 
species, thinks that it must originally have been found nearer 
the coast, as it is unlikely that any earlier traveler had 
visited the remote solitudes where Dr. Welwitsch found it. 

The whorls are smooth except for weak growth-striae, and 
are parted by a linear suture which is transparent-margined 
below. The fifth whorl appears disproportionately wide. 
The spire tapers rapidly near the obtuse apex, but much more 
slowly throughout the greater part of its length. The ex- 
cision at the base of the columella is not very deep. Ex- 
amples measure: 

Length 17.5, diam. 6, aperture 6.2 mm.; whorls

Length 16.5, diam. 5.7, aperture 6 mm.; whorls 

88. G. HYALINA (Rang). PL 14, fig. 16. 

Shell long-oval, smooth, glossy, very thin, transparent and 
of a pale yellow tint, like horn. The spire is quite elevated 
and obtuse, composed of 6 slightly rounded whorls, the last 
one larger than all the others. Aperture oval, rather long, 
its plane parallel to the axis. The columella has a projecting 
lobe ; its edge is a little reflexed. Right margin unexpanded 
and thin, simple and 'Continuous with the columella. Length 
7 to 9, diam. 3 to 4 mm. (Rang) . 

Liberia: Mesurade, in crevices of rocks at the foot of the 
cape not far from the sea (Rang).

Known to me by the above account only. 

Group of G. paritura (Section Neoglessula, nov.) 

Embryonic whorls very minutely and not closely engraved 
spirally, successively lengthening vertical grooves appearing 
on the later ones; whorls of the neanic and adult stages 
closely, regularly rib-striate, base smoother. Viviparous. 
Type G. paritura. 

Several species from the northern shores of the Gulf of 
Guinea form a group having adult sculpture somewhat as 
in Pseudoglessula, but embryonic sculpture of their own. 
Only one of these is known to me by specimens; the others 
are still known by the original lots only. 

89. G. PARITURA (Gould). PL 14, figs. 17, 18, 19. 

Shell elongate, thin, glossy, pale corneous, longitudinally 
closely lirate; spire turrite, obtuse at the apex. Whorls 7, 
convex, the last about half the total length of the shell. 
Suture deep. Aperture narrow, somewhat ear-shaped. 
Columella deeply arcuate, involute, forming a basal channel. 
Length 1, width .35 inch. (Old.).

KOBELT, Conchyl. Cab. p. 92. 

This species is viviparous. The summit is semi globular ; 
first 1% whorls smooth in adults, but in young shells they 
show sparse engraved spiral lines; then vertical grooves ap- 
pear below the suture, short and widely spaced at first, but 
gradually lengthening and becoming closer, so that at the 
end of 2y 2 whorls they reach nearly to the suture below, and 
become so close that the sculpture may be described as rib- 


etriate, the riblets smooth, rounded, and about equal to the 
intervals. On the face of the last whorl there are five or six 
riblets in one millimeter. The riblets weaken or disappear 
almost abruptly at the periphery of the last whorl, leaving the 
base and a very narrow band above the suture almost smooth. 
The columella is formed just as in the Indian Glessulae, being 
deeply concave, thickened with a white callus, and abruptly, 
deeply truncate at the base. The shell is translucent whitish 
under a very thin pale yellow cuticle. A specimen of the 
ordinary size measures, length 20.3, diam. 8.8, aperture 8.3 
mm.; whorls 6 l / 2 . 

An embryonic shell, shaken out of an adult, is oval, 4.7 
mm. long, with 3 whorls. There is a distinct umbilical slit 
behind the columellar callus (pi. 14, fig. 19). 

90. G. BRETIGNEREI Chaper. PL 14, fig. 20. 

Shell thin, transparent, of a light gray-olive tint; shining, 
though sculptured with very regular, crowded striae of 
growth, well-marked from the end of the second whorl. Spire 
of 6 or 7 whorls, very regularly conic after the second whorl. 
Aperture oblique; columella strongly inflexed towards the 
interior of the aperture. No umbilicus. Length 30, diam. 
11 to 12 mm. (Chaper).

This species differs from G. paritura only by its larger 
size, so far as the published account goes. Kobelt confused 
the name with that of Corbula assiniensis, which occurs on 
the next page of Chaper 's paper. 

91. G. MALAGUETTANA (Rang). PI. 14, fig. 15. 

Shell elongate, conic, thin, subdiaphanous, very minutely 
longitudinally striate, brown-buff. Apex obtuse. Aperture 
oval, the columella arcuate, truncate; lip simple, acute. 


Length 15 to 20, diam. 8 to 9 mm. Animal dirty buff, 25 
mm. long. (Rang).

malaguetana BECK, Index, p. 77. 

This shell, according to Rang, is long, conic, thin, almost 
diaphanous, very finely and regularly striate; the very thin 
cuticle covering it is of a dirty yellowish brown, resembling 
that of Subulina striatella. The summit is obtuse, and its 
whorls, 6 in number, are quite rounded. The aperture is 
oval, little oblique. The columella is very concave and trun- 
cate in front; the right margin is straight and thin, fragile 
and acute. Deshayes gives the dimensions 22 x 8 mm. The 
systematic position is unknown, and it may prove to be a 
Pseudoglessula. The spire is more slender above than in 
G. paritura. 

92. G. SERICINA (Jonas). PI. 14, figs. 13, 14. 

Shell ovate-turrite, rather thin, longitudinally closely pli- 
cate, pellucid, glossy, straw-colored. Spire turrited, the apex 
very obtuse. Whorls 6 to 6%, convex, the last about three- 
sevenths the total length, obsoletely angulated in the middle, 
smooth below the angle. Columella very arcuate, highly and 
widely truncate, the aperture suboval. Length 17, diam. 7 
mm., aperture 7y 2 mm. long, 4 wide in the middle. (Pfr.)

Pfeiffer renamed the species Achatina antoniana, Mono-

It should be observed that the names lanceolata, cornea,

Bulimus, hence must be dropped as homonyms in Rumina, 
even if the races denoted are valid, which seems doubtful.

Mr. E. A. Smith (Proc. Malac. Soc. London VII, p. 313) 
has called attention to my failure through oversight to in- 
clude Achatina dennisoni Reeve in the Manual. He has also 
discussed the characters and synonyms of that and other 


I 'H 

species of the group Hemibulimus, correcting various errors 
which, by reason of the scarcity of material, had been per- 
petuated from author to author. 

The relation of Hemibulimus to Liguus is not very close 
and I now doubt the propriety of including them in one 
genus. Except in the structure of the columella, Hemi- 
bulimus is very similar to Porphyrobaphe.

Reeve described and figured a shell from the Dennison col-

figure (copied on pi. 40, fig. 1) shows a pale red-brown shell 
with decidedly attenuate early whorls, a brown-spotted sub- 
sutural band, and two other pale bands on the last whorl. 
The parietal wall is purplish but not black. The aperture 
is markedly acuminate above. Judging from the description

and figure, the sculpture is not so strong as in the following 
form; yet it must he remembered that the sculpture is usu- 
ally minimized in Reeve's figures of Achatina. 

H. D. CARUS Pils., n. var. PL 40, figs. 2, 3, 4, 6. 

The shell is elliptic-ovate with a rather slender spire and 
obtuse apex; solid and strong. Nearly 2% smooth, convex 
whorls form the semiglobose embryonic shell. The next whorl 
is lightly striate, near its termination the surface becomes 
minutely plicate and spiral grooves appear ; on the next whorl 
it is closely and finely plicate, the plicaB cut by several (usually 
5 to 7) spiral furrows, which appear as if scratched in a 
plastic surface. On the last whorl the fine plica become 
weaker, irregular, often more or less obsolete towards the end 
of the whorl; there is more or less indistinct malleation, and 
some irregularity due to former growth-arrest periods, marked 
by dusky streaks, of which there may be one to four or more 
on the last whorl. The aperture is elliptic-pointed, outer lip 
obtuse, more or less thickened, expanded or effuse towards the 
base. Columella arched, usually very deeply, but sometimes 
only moderately, its lower portion colored like the outer lip; 
base truncate, parietal callus glossy Hack, overlaid with blu- 
ish inwardly. Color as follows : 

(1) Ground-tint yellow, fading towards the apex: (a) 
brown spots below the suture appearing on the first post- 
embryonic whorl, becoming broad, more or less fulgurate 
stripes on the penult, and next earlier whorls; last whorl 
showing three narrow equidistant bands and an irregular 
mottling of the yellow ground, elsewhere olive and brown of 
varying shades; outer lip and lower half of columella edged 
with vermilion. (6) intermediate whorls of the spire marked 
with narrow, close, wavy brown streaks; antepenult, whorl 
with some subsutural spots, last whorl without bands, irregu- 
larly streaked with dull green on a greenish yellow or light 
yellow green ground; outer lip and basal half of columella 
bright ochre. 

(2) Ground-tint reddish, (c) nearly uniform ochraceous 
reddish, the red predominating on the earlier whorls; outer 


lip dull red, fading to pink in the throat, (d) first post- 
embryonic whorl with subsutural spots, next whorl or two 
closely streaked with dull red-brown; last whorl of a muddy 
olivaceous shade, with some darker brown streaks; lip with 
a narrow red edge and dark submargin.

This form differs from Reeve's figure of A. dennisoni by 
its intensely black parietal callus, and the shape of the aper- 
ture, which is wider, less acuminate above, the outer lip be- 
ing arcuate and not straightened near the insertion. 

Reeve's figure 33, (copied in Manual XII, pi. 36a, fig. 30)

Soft anatomy of Partula. 

The first anatomical observations on Partula were by 
Ferussac, who discovered that these snails are viviparous. He 
erroneously states that they have no tentacles, only the eye- 
pedicels. The next work was by Heynemann, who figured 
the teeth of P. Urata. 

The following species of Partula were dissected by Dr. C. 
Semper (Reisen im Archipel Philippinen, Landmollusken, 
pp. 158, 159) : P. canalis semilineata, recluzwna, Urata (pi. 
17, f. 18, jaw), hyalina (pi. 16, f. 21, genitalia), lineata, 
otaheitana (pi. xii, fig. 21, genitalia), vanikorensis (pi. 17, 
f . 17, teeth) . P. lineata was probably not correctly identified. 

In 1875 (Proc. Acad. N. S. Phila., p. 244) Mr. W. G. 
Binney examined the anatomy of numerous Raiatean species : 
P. fusca (pi. 19, f. 9, genitalia), citrina, planilabrum ab- 
Ireviata, umbilicata (pi. 19, f. 7, genitalia), bilineata (pi. 19, 
f. 10, genitalia), amanda (pi. 19, f. 4, teeth), virginea (pi. 
19, f. 8, genitalia, f. 11, jaw), and gracilis, besides several 
unidentified species. Some of the same information is re- 
peated in Annals of the N. Y. Acad. Sci. iii, p. 127. 

I have examined more or less fully P. rosea, P. varia, P. 
arguta and some unidentified Raiatean species received with- 
out the shell. 

We have therefore some knowledge of the soft parts in 
species of the sections Partula, Leptopartula, Samoana, and 
Thakombaua, inhabiting the Society, Samoa and Fiji groups. 

Animal externally like that of Bulimulidce or Helicida; 
blunt before, the tail long, gradually tapering. There are 
no pedal furrows, -and the sole is undivided. Dorsal grooves 
weak, but the genital furrow is well developed. Genital pore 
behind the right tentacle, as usual. The lafoial processes are 
rather large. The mantle has very small right and left 
lobes. The tentacles are as well developed as usual in land 
snails (pi. 32, fig. 10, P. canalis). 

Garrett writes: "The examination of the animals of the 
various species has convinced me that they possess no re- 
liable external features that will aid in their determination. 


The coloration in all the species varies from pale cinereous, 
through all the intermediate shades, to black or dusky slate. 
The .arboreal species are generally lighter colored than the 
ground species, and have a more expanded creeping-disk. 
The animals of P. arguta } annectens, turgida and attenuates, 
have the ocular tentacles longer and more slender than the 
other species, and the exudation of mucus is much more 
copious and more viscid or tenacious than usual, resembling 
in that respect the same difference as exists between the typi- 
cal Helices and the arboreal Naninae." 

The pallial organs are characterized by the short, more 
or less triangular kidney, -with a direct ureter which does not 
extend to the 'Collar, and opens by a lateral pore. The peri- 
cardium is as long as the kidney. The surface of the lung 
shows no visible venation. It is densely peppered with 
light dote (probably calcareous) arranged in irregular lon- 
gitudinal lines. In P. arguta these light dots are present in 
spots and stripes (pi. 42, fig. 4), but in other species examined 
they are equally and densely spread over the whole surface. 

In P. rosea (pi. 42, fig. 5, x 3) the kidney is very short 
and strictly triangular. According to Semper, that of P. 
canalis seems to be of the same form. In P. arguta (pi. 42, 
fig. 4) the kidney is relatively larger, and the pericardium 
lies parallel to its longer axis. The ureter also is longer. 
In an undetermined Raiatean species (doubtless of the re- 
stricted section Partula) the kidney approaches the band- 
like type (pi. 42, fig. 6), yet it is somewhat triangular, and 
equal to the pericardium in length. This is probably the 
prevalent shape of kidney, since Semper mentions that all 
the species examined by him except canalis had the kidney, 
"bandformig. " In most of the subgenera the kidney is 

The alimentary canal is of the usual four-folded type. 
There is a fusiform crop (pi. 42, fig. 5). 

The jaw is very thin and transparent, varying from slightly 
arcuate to horseshoe-shaped, similar to that of Drymaus 
and Zaplagius, formed by the union of many narrow delicate 


plates, which converge towards the middle, so that there are 
short plates where the two series meet (pi. 42, fig. 1 jaw of 
P. lirata, after Semper; fig. 2, central portion of jaw of 
P. gracilis Pse., after Binney). 

The number of plates on the two sides is unequal, there 
being in lineata 27.36, in recluziana 34.38, in otaheitana 40.50 
according to Semper. 

The radula is broad. The teeth form thrice bent transverse 
rows, as shown in pi. 15, fig. 11, a half row of teeth of 
P. lirata. The central teeth have the usual quadrate basal 
plates. In P. amanda, P. rosea, P. varia etc. the length of 
the basal plate is about twice its width in the middle; the 
middle cusp is long, reaching to or over the posterior border 
of the basal plate. Side cusps represented by cutting-points 
only. The lateral teeth are larger, with the mesooone longer, 
outer cusp well developed with a strong cutting-point (pi. 
43, fig. 1, P. varia huaheinensis Garrett; fig. 2, P. rosea 
Brod.). There are 11 lateral teeth on each side in P. rosea 
and planilabrum ; 10 in abbreviate, amanda, otaheitana ; 8 or 
9 in varia, umbilicata, virginea, bilineata, hyalina, lineata, 
recluziana, canalis-, 5 in gracilis. The marginal teeth are 
peculiar in form, having a long, curved basal plate and 3 
cusps, the inner largest, the other two directed outward (pi. 
15, fig. 8, 13th to 15th teeth of P. rosea) . They are numer- 
ous, over 120 in P. virginea. 

The Fijian P. lirata differs from the Society Island species 
examined by Binney and myself by having the central and 
lateral teeth shorter and wider, the central scarcely longer 
than wide. There are 7 lateral and over 50 marginal teeth, 
the latter of typical shape (pi. 15, figs. 11, 12, P. lirata after 
Heynemann) . 

The radula has been examined in numerous species from 
the Society, Fiji and Samoan Islands, by Heynemann, Binney, 
and Semper. I have examined it in P. rosea and varia. 

Genitalia (pi. 43, fig. 5, P. rosea). The penis is well de- 
veloped. It is more or less distinctly contracted near the 
distal end, which is swollen. Internally the lower portion is 



coarsely wrinkled, the upper portion densely granulose and 
coarsely plicate. The retractor muscle is terminal. The vas 
deferens opens below a papilla situated at about the lower 
third of the granulose portion ; it is therefore not terminal on 
the penis. It is superficially bound to the penis, to the 
vagina and the basal part of the spermatheca, then free as 
far as the upper end of the oviduct, where it is again adnate 
for a short distance. The ovisperm duct is strongly knotted, 
as usual. The basal part of the spermatheca-duct is much 
swollen in P. rosea and P. fused, the distal end tapering; 
but in P. bilineata (pi. 43, fig. 3, after Binney) umbilicata, 
virginea, otaheitana and hyalina the spermetheca is oblong, 
obtuse distally, and seated upon a slender duct. In all the 
species which have been examined the duct is short. 

Reproduction seems to be ovo- viviparous. The upper part 
of the oviduct contains oblong egg-capsules having a cal- 
careous shell, which lower down in the oviduct becomes dis- 
solved or is consumed by the embryo. From one to five eggs 
or young are found in one individual. 

Free muscles: In P. rosea (pi. 43, fig. 4). The pharyngeal 
retractor is free to its proximal insertion. At about the 
middle of its length the left ocular and tentacular retractor 
band joins it, and a little farther out the anterior pedal re- 
tractors branch off. The broad posterior pedal retractor 
(tail retractor or columellar muscle) remains united far 
forward with the right ocular and tentacular retractor, which 
gives off a group of small anterior pedal retractor muscles. 
The right ocular band passes between the male and female 
branches of the genitalia. 

This muscle system differs from that of Achatinella dolei 
chiefly by the union of the right ocular with the tail retractor. 
In Achatinella both ocular bands are free. 

Relationships of Partulidce. 

This family is one of the most sharply defined in the 
Orthurethra. By its short kidney, about equal to the 
pericardium, it differs conspicuously from the Enidce, 


Ferussacida, Amastridce and Achatinellidx?, all of which 
have the kidney very long, far exceeding the pericar- 
dium. For comparison I figure the pallial region of Ena 
reiniana (Bulimimis reinianus Kob.), pi. 42, fig. 3, x 2. In 
the genitalia, the Partulida are remarkable for the absence 
of an appendix, the penis being simple. This organ is pres- 
ent and highly developed in all the other families. The vas 
deferens is practically free from the oviduct, its. adhesions 
being merely superficial. This is a somewhat unusual con- 
dition, 'and where found it seems to be associated with vivip- 
arous reproduction. The shell is rather characteristic; in 
form some Enidce are similar, yet the spirally striate em- 
bryonic whorls are unlike that family, and are an invariable 
feature of Partulid<z, though occasionally this sculpture is 
lost by wear in adult or old shells. This is not in itself a 
feature of much importance, yet so far as I know, there is 
no other Bulimoid snail with an expanded or reflexed lip 
which has spirally striate embryonic whorls. 

From these comparisons it will be seen that the Partulida 
stand somewhat isolated. There is no family of Bulimoid 
or Achatinoid Orthurethra which can be said to be nearer 
than any other to the Partulida, so far as present informa- 
tion goes. 


In dealing with Society Island species both Mr. Grarrett 
and Dr. Hartman have called attention to certain specimens 
of intermediate character which they looked upon as hybrids 
between species commonly considered to be distinct. Gurrett 
writes as follows: " Hybrids between P. elongata and P. 
toeniata, and between P. garretti and P. thalia, are so com- 
mon where those species come in contact, that I am inclined 
to believe they possess a certain degree of fertility. I have 
also detected several hybrids between P. faba, var. subangu- 
lata, and P. virginea ; one between the arboreal P. imperforata 
and the terrestrial P. lugubris; two between P. lineata var. 
strigosa, and P. toeniata; about a dozen between the arboreal 


P. faba and the terrestrial P. radiata-, a number 'between 
P. faba and P. fusca, and many between the latter and P. 
navigatoria, as well as many between the latter and P. faba. 
I failed to detect hybrids between the Tahitian species, and 
found none at Huaheine. ' ' 

As a general proposition, apparent evidence of hybridism 
among land snails is so unusual in a state of nature that 
one is inclined to believe that well-established species very 
rarely hybridize. In the few species tested experimentally 
(such as Lang's crosses between Helix nemoralis and 
hortensis) the progeny are not abundant and crosses between 
them are almost sterile. It must be remembered, however, 
that the Moorean and Baiatean species mentioned as hybrid- 
izing by Garrett v are very closely related forms, which have 
for the most part scarcely reached the "specific" stage of 
differentiation; hence it is not inherently improbable that 
hybrids occur. 

In the case of species between which supposed hybrids are 
"common," I would rather explain the intermediate forms 
occurring on the overlapping confines of the two "pure" 
races as an undifferentiated remnant of the parent stock 
which has elsewhere become "specifically" differentiated. 
Pending experimental evidence to the contrary, this view 
seems in accordance with what seems to occur in a multi- 
tude of other cases, whereas hybridism on an extensive scale 
is certainly a very rare condition. 

Variation in Partula. 

Extended study of variation does not come within the plan 
of the present work, the purpose of this Manual being the 
definition of species and their systematic classification. 
Moreover, the materials for a study of variation large, un- 
selected series of shells are not accessible to me; my per- 
sonal knowledge of them is restricted to museum specimens, 
which as usually preserved and labelled give little idea of the 
association of forms or the conditions of their existence. 
Some general considerations bearing upon variation may how- 
ever be in order. 


Most species of Partula are neither more nor less variable 
than the generality of snails living in exposed situations 
elsewhere. It is only in the Society Islands that species oc- 
cur having a variety of well-developed color-patterns. In this 
respect they resemble many other genera of arboreal snails, 
such as Amphidromus, Liguus, Hemitrochus, Polymita, 
Drymceus etc., etc. All arboreal snails were derived from 
terrestrial forms ; and almost invariably, with arboreal habits 
they assume variegated color-patterns. In many cases the 
colors or patterns seem to be protective (cryptic or warning), 
but as often they are not so, to our eyes. The color-patterns 
in arboreal snails seem to be very readily modified, new 
sports or mutations arising, which are perpetuated, prob- 
ably in Mendelian ratio, in the parent colonies. This has 
not yet been tested experimentally in Partula ; yet from the 
complex nature of many colonies,, in which snails of several 
distinct color-patterns co-exist and interbreed (being found 
together in the uterus of a single mother) , I have little doubt 
that pedigree cultures would reveal a Mendelian mixture. 

Another 'Common 'condition among tree-snails is the sim- 
plification or absence of pattern, by variation in the "color- 
factor/ 7 whereby patterns characteristic of species or phyla 
become in part or entirely latent in individuals or races. 
Cf. the Pentatceniate snails, Drymczus, Amphidromus etc. 
Some species of Partula, such as P. hyalina, are apparently 
albinistic; but in at least a part of these (P. arguta) the 
mantle is variegated, showing through the transparent shell, 
which in life should vicariously show a pattern. 

Probably most "species" of snails and other sedentary 
animals are in reality more or less complex groups, though 
in plain-colored forms their composite constitution is not 
obvious. In some of the plain, ground-living American snails, 
such as Omphalina, the diversity in number of teeth of the 
radula among different colonies points to this conclusion. 

In the Society Islands, where alone the distribution of 
Partula has been studied, most species and races are strictly 
limited to small areas, a single valley, or several 'contiguous 


^valleys. The topographic harriers (ridges unsuitable for 
Partulae) are evidently older than the races so isolated, which 
are the modified descendants of stocks once widely diffused. 
Diverse mutations soon result in racial differentiation in 
-such isolated colonies, whether the process can be aided by di- 
versity of environment or not. On a small scale this is illus- 
trated by the 'Colonies of Helix nemoralis in Burlington, New 
Jersey, all descended from a single colony planted about 50 
years ago, yet now showing incipient racial traits in the 
several colonies scattered over the town. 

Gulick, in his ''Evolution, Racial and Habitudinal" p. 220 
has directed attention to the fact that arboreal snails do not 
have the facility in migrating enjoyed by terrestrial species, 
and hence are more subject to local differentiation brought 
about by isolation. 

Dr. A. G. Mayer writes : "It is probable that geographical 
isolation plays a most important part in the formation of 
new species. If two valleys be adjacent, their snails are 
closely related each to each, whereas the wider the separation 
between any two valleys, the more distant the relationship 
between their snails. The ridges between the valleys, being 
either barren or covered with vegetation unsuitable to the 
snails, affords barriers over which the animals must find it 
more or less difficult -to pass. Thus the Partulae in the 
Tahitian valleys are isolated very much as are the Achati- 
nellidse of Oahu in the Hawaiian Islands. 

"In Tahiti the snails are most abundant in the valley- 
bottoms, where they usually occur on the under sides of the 
leaves of Caladium and Plantain, although in some valleys 
they are frequently found on DracaBna and Turmeric. Al- 
though more abundant in the bottom, they extend for some 
distance up the sides of the valley and appear to be present 
in most places where the plants which they affect are found. 
As far as the very limited observation of the writer goes, 
there appears to be no difference in the character of the 
snails in different parts of the same valley. The difference 
between any two adjacent valleys is, however, very marked."

Fossil Partulida. 

No fossil Partulae are known. The ancestors of this family 
lie buried under the South Pacific. Several Eocene and 
Oligocene species have been described as Partulse, as follows : 

Partula americana Heilprin, Trans. Wagner Free Institute 
of Science i, p. 115, pi. 16, f. 60 (1887) ^Hyperaulax 
americanus (Heilprin), Man. Conch. XIV, p. 103. Oligocene, 
Tampa Silex bed, Florida.

lichen Akademie der Wissenschaften vol. 57, 1890, p. 125, 
pi. 2, f. 10-10&. Zeitschrift Deutschen Geol. Gesellschaft, 
vol. 47, 1895, p. 104. Eocene. Red tuffs of Capitello, Sta. 
Catterina above Altissimo, etc.

Royale Zoologique et Malacologique de Belgique, xli, 1906, 
p. 280, pi. 8, f. 267&is-l. Sparnacien stage of the Eocene,, 
at Grauves, Paris Basin. 

The reference of these forms to Partula is purely fanciful. 
The American species is referable to a genus of Bulimulidse, 
Hyperaulax. Well-preserved specimens have not the 'char- 
acteristic apical sculpture of all known Partulidae. The- 
European Eocene forms offer no character whatever separ- 
ating them from "Buliminus" (Enidae). Their reference 
to Partula rose from the fallacious method of trying to exactly 
match the fossil shell with some recent species, ignoring the 
obvious fact that details of contour are constantly changing 
in the evolution of any group, and offer no features diagnostic 
of genera in Bulimini, Bulimuli or Partulse. The Eocene 
forms in question have not been shown to have the embryonic 
sculpture of Partula. 

Classification of Partulida. 

This family contains the single genus Partula. It is quite 
possible that when the forms of Micronesia, Melanesia etc. 


are investigated anatomically, a further generic division 
may fee made. There are two rather dissimilar forms of 
kidney among the Polynesian species, though at present we 
do not know enough species anatomically to utilize this fact 
in taxonomy. By conchological characters nine divisions are 
indicated, herein called "sections." In all cases these sec- 
tions are geographically limited to single island-groups, or 
to several adjacent groups. Five of the nine sections of 
Partulce have already 'been named 'by Dr. Hartman, who 
unfortunately used preoccupied names, and in most cases 
understood the groups in limits different from mine. He 
also split the typical group of Partulae into numerous sub- 
genera which seem to me superfluous. The sub genera here- 
in established are as follows. 

MARQUESANA Pilsbry. Embryonic whorls coarsely pitted 
along the spirals; post-embryonic whorls with very well de- 
veloped spiral lines ; lip thin but often widely reflexed ; colors 
not bright, a subperipheral band frequently present, but 
no others; cuticle thin, often deciduous. Type P. gany- 
medes. This group includes all known Marquesan species, 
no. 1 to 6. 

LEPTOPARTULA Pils. Shells ovate with short spire, com- 
posed of few (4 to 4%) whorls; very thin and fragile, sub- 
transparent, pale colored; aperture large, ovate, toothless, 
lip expanded, not thickened. Type P. arguta. Huaheine and 
Raiatea, Society Is. Species no. 7 -and 8. 

PARTULA s. sir. Shell ovate, usually solid and with opaque 
coloring, often in bands or streaks ; lip thickened within, the 
callus not extending to the upper insertion; parietal wall 
often toothed. Society, Austral and Hervey Is., species 9- 
52, and probably Samoan and Tonga Is., species 60-62. 

SAMOANA Pils. The shell is very openly umbilicate, dex- 
tral or sinistral, with flatly reflexed lip and no teeth. Type 
P. canalis. Samoan Is., species 53 to 58. 

THAKOMBAUA Pils, Shell rimate, long-ovate, the later 
whorls sculptured with coarse spiral cords. A low callous 
tubercle on the parietal wall far within. Type P. lirata, no. 


63. Fiji Is. This is the only group having raised spiral 

MELANESICA Pils. Shell rimate or umbilicate, ovate or 
pyramidal, thin, corneous, greenish-yellow or pale brown, 
uniform or obliquely streaked, not banded; aperture simple, 
the peristome expanded or reflexed. Type P. turneri. Me- 
lanesia, one species in Samoa. Species no. 59, 64 to 101. 

A large group of species simple in form and coloring. 

PALAOPARTULA Pils. Long forms with the spire 
straightly conic, embryonic whorls high, the later ones 
deeply engraved spirally, saccate below. Umbilical area 
very ample, deeply perforate ; aperture unusually long, tooth- 
less, the lip thin and very broadly reflexed. Type P. thetis. 
Pelew Islands. Species 102 to 104. 

CAROLINELLA Pils. Perforate, rather solid, opaque and 
ventricose species of dull or brown coloration, aperture large 
and toothless. They have the appearance of ground snails. 
Type P. guamensis. Caroline Islands. Species 105 to 107. 

MARIANELLA Pils. Shell ovate or inflated, with a small 
umbilicus, the lip somewhat thickened within, parietal wall 
plain or bearing a low nodule deep within; colors rather 
bright. Type P. gibba. Marianne Is. Species 109 to 111. 

Geographic distribution of the Partulidce. 

Snails of this family are confined to the high islands of the 
south and western Pacific. Not one species has ever been 
found on an atoll or low island. In most island groups all 
of the Partulae belong to a single stock, but in a few, notably 
the Society and Samoan groups, several phyla are repre- 
sented. Each of the subgenera or sections is confined to a 
single archipelago, or to several adjacent island- groups; and 
with the single exception of P. hyalina, no species is known 
to inhabit more than one island-group, while a great majority 
of the forms live on but one island. The distribution of 
Partulse is remarkably consistent, and lends no support to the 
idea that their dispersal has been due to drifting by ocean 
currents, or any other "accidental" means of over-sea carri- 


age. Their distribution is what would foe expected were the 
present archipelagos remnants of a former continent, now iso- 
lated by subsidence. This continent, from the absence of all of 
the higher families of land snails on the islands remaining, I 
have conjectured to have been isolated since Palaeozoic times, 
though the final dismemberment of its various components 
was doubtless much later. (See Pilsbry, The Genesis of 
Mid-Pacific Faunas, Proc. Acad. Nat. Sci. Phila. 1900, p. 568) . 
Such groups as the Society Islands or Fijis may well have 
existed as rather large land masses as late as middle Tertiary 
times. Indeed, this hypothesis would seem to be an essen- 
tial part of any attempt to explain the distribution of land 
snails in most of the groups of high islands. 

The most convenient grouping of species for the purposes 
of this monograph is by geographic range. The following 
divisions are used. 

I. Marquesas Islands, species 1 to 6. 
II. Society Islands, species 1, to 50. 

III. Austral and Hervey Islands, species 9, 52. 

IV. Samoan Islands, species 53 to 60. 

V. Fiji Is., Rotuma and Tonga Is., species 61 to 63. 
VI. New Hebrides and Santa Cruz groups, species 64 to 80. 
VII. Solomon Islands, species 81 to 91. 
VIII. New Ireland, New Britain, etc., and Admiralty Is., 

species 92 to 96. 
IX. Louisiade Archipelago, including Trobriand and 

Woodlark Is.; New Guinea. Species 97 to 100. 
X. Talauer Is., species 101. 
XI. Pelew Islands, species 102 to 104. 
XII. Caroline Islands, species 105 to 108. 

XIII. Marianne Islands (Guam), species 109 to 111. 

XIV. Snails of other genera described as Partulae. 

XV. Species of uncertain or unknown habitat, species 12, 
21, 47, 48, 49, 50, 51, 60, 72, 86, 94.

11, type P. decussatula (not JEga Leach, 1815). Latia 
Hartm., op. cit. p. 12, type P. ganymedes Pfr. (not Latia 
Gray, 1849). 

Partulae having the embryonic shell coarsely pitted along, 
the spirals; post-embryonic whorls with very well developed 
spiral striation ; lip thin but often wide. Colors not bright ; 
the cuticle thin, often deciduous; a subperipheral band fre- 
quently present, but no others. Type P. ganymedes. 

Species of Partula are known from five of the nine high 
islands of the Marquesan group, the others being unknown 
eonchologically. They are distributed as follows: 

Nukuhiva: P. strigata varieties. 

Huapu: P. strigata (?), P. bellula. 

Hivaoa: P. inflata, P. ganymedes, P. bellula, P. decussatula. 

Tahuata: P. inflata. 

Fatuhiva: P. magdalinae. 

The predominance of species on Hivaoa may be due to its 
being more fully explored. It is the largest island next to 
Nukuhiva. The proportion of species recorded as common to 
two islands is remarkable, if indeed it proves to be the fact. 
It seems likely that further research would greatly augment 
the brief list of Marquesan Partulas. 

P. spadicea Reeve, reported from the Marquesas, is a 
Society Island form. 

Key to Marquesan Partulcz. 

Whorls over 5; peristome broad, white, strongly calloused 
within ; shell opaque. 

a. Very obese, the diam. more than % the length ; last whorl 
humped. P. inflata, no. 1. 

aa. Oblong-conic, the last whorl rounded. 

b. Surface partly nude, but having a band of cuticle; 
length 20-23 mm. P. ganymedes, no. 2. 


bb. Surface covered with a pale greenish cuticle, length 
about 21.5 mm. P. recta, no. 3b. 

Whorls less than 5 ; peristome narrower or tinted, not very 
strongly calloused. 
a. Aperture less than two-thirds the length of the shell. 

b. Olive-brown, brown or white, opaque; lip narrow; 
length 17 to 21 mm. P. strigata, no. 3. 

bb. Pale olive or greenish-yellow, thin, somewhat trans- 
lucent; length 14 to 17 mm., whorls 4%. 

P. bellula, no. 4 ; P. decussatula, no. 5. 

aa. Aperture two-thirds the length of the shell; shell thin, 
fragile, with a pale yellowish cuticle ; length 14 to 15 mm. 

P. magdalincz, no. 6. 

1. P. INFLATA Reeve. PI. 30, figs. 1, 2, 3. 

Shell openly umbilicate, globose-conic, rather thin, luster- 
less or nearly so, varied in color: (1) white, usually with 
some trace of an olive subperipheral band. (2) white, suf- 
fused and obliquely streaked with brown in a broad median 
belt, abruptly darker below the periphery; spire corneous. 
(3) reddish or dull chestnut brown, more or less streaked, 
and sometimes white below the sutures; reverse of the lip 
and columella white. Of the 2% embryonic whorls the first 
half whorl or more is smooth, the rest pitted along the spirals. 
The rest of the shell is sculptured with very distinct, >close 
waved spiral striae. Spire is straightly conic, suture moder- 
ately impressed. Whorls 5%, convex, the last whorl swollen 
in the peripheral region except for the space of a third or 
fourth of a whorl behind the lip, where it is compressed ; this 
gives a humped appearance to the back of the shell. Aper- 
ture ovate; lip broad, white, flatly reflexed, thickened with- 
in; columella broad, with a deep-seated fold above, visible 
in oblique view. 

Length 23, diam. 17 mm. 

Length 21, diam. 16.7 mm.

Remarkable for its gibbous last whorl and 'broad white lip. 
The very thin cuticle is more or less wholly lost in most 
adult shells. The examples described are from the island of 
Taiwata (= Tahuata) ; whether those reported from Dom- 
inique, the next island of the group, are identical with them 
in all respects I do not know. 

2. P. GANYMEDES (Pfeiffer). PL 30, figs. 4, 5, 6, 7. 

Shell umbilieate, oblong-conic, thin, minutely, strongly, de- 
cussated with close growth-lines and extremely close, im- 
pressed, wavy, spiral lines; dead white under a very fuga- 
cious greenish-yellow epidermis. Spire conic, rather acute. 
Whorls 5%, a little convex, the last about as long as the spire, 
very obsoletely angular in the middle, ornamented with one 
rather wide chestnut band. Columella straightened. Aper- 
ture oblong, obliquely truncated above ; peristome simple, thin, 
broadly expanded throughout. Length 23, diam. 10%, aper- 
ture inside 10% x 5 mm. (Pfr.).

This species is variable in size, the degree to which the 
cuticle is lost, and the color of what remains. Specimens of 
one lot measure: 

Length 22, diam. 13, length aperture 12.8 mm. ; whorls 5%. 

Length 20, diam. 11.3, length aperture 11.1 mm. ; whorls 5%. 

In the typical form, the very thin pale green cuticle is. 


either entirely lost, or only a 'belt remains at and below tire 
periphery, in adult shells. The upper edge of the subperi- 
pheral brown band often shows as a thin line above the sutures 
of the spire; but frequently a mere brown line replaces the 
band, and is concealed on the spire (fig. 5). 

In another form of the species, the cuticle is removed in a 
zone below the suture. This zone may be wide or narrow; 
the remaining portion of the last whorl usually half to three- 
fourths is covered with greenish or dull brown cuticle. 
These variations seem to be characteristic of different colonies. 

The beautifully developed spiral striation is 'Characteristic 
of all forms. The lip is flatly reflected, thickened at the inner 
rim, and rather abruptly narrowed near the upper angle. 
The umbilical crevice is widely open. 

3. P. STRIGATA Pease. PI. 30, figs. 8, 12. 

The shell is openly umbilicate, acutely ovate, rather thin, 
dingy olive-brown, the latter part of the last whorl light 
cream-brownish with a few darker oblique streaks, and an 
orange streak in the angle behind the lip. Sculpture of fine, 
waved spiral lines. Embryonic shell of 2% whorls, coarsely 
pitted in spiral lines except the smoothish initial half whorl. 
Whorls 4%, convex, the last evenly rounded. The aperture is 
ovate, oblique, peristome flesh-tinted, flatly reflexed, rather 
narrow, thickened within except near the upper angle. 
Length 19, diam. 10.8, aperture 10.8 mm.

p. 202. GARRETT, Journ. A. N. S. Phila. ix, 1884, p. 80. 

The types, one of which was figured in A. J. C. iv, are before 
me. The above description and figs. 8 and 12 were drawn 
from them. Pease gave simply Marquesas as the habitat, but 
Garrett >stated that ' * Pease 's shells were collected by a native 
missionary residing on Woapo." This island lies south of 
Nukahiva. In his Marquesan -catalogue of 1887 Garrett 
places strigata as a synonym of recta, without remark. 


Whether the specimens were actually taken on Huapu 
("Woapo") or not remains uncertain. 

Compared with the type lot of Pease 's P. recta, P. strigata 
is thinner, darker colored, dull brownish instead of pale green, 
with a narrower flesh-tinted peristome. The two lots seem 
to be specifically distinct, until studied in connection with a 
large series from Nukahiva, subsequently obtained, which 
seem to be partially intermediate. 

3a. P. STRIGATA OBESIOR Pils. PI. 30, figs. 11, 14, 15, 16. 

A lot of 27 examples from Nukahiva consists of shells which 
are generally more globose than either recta or strigata, thin, 
variable in color as follows : 

a. White, denuded of cuticle (fig. 14). 

6. White, 'Covered with a very thin straw, cream or brown 
tinted cuticle, the spire often corneous (fig. 15). 

c. Busty brown, having a whitish belt below the suture (fig. 

d. Dark brown (fig. 11). 

In nearly all of this lot the lip is thin and narrow, as in 
strigata. Specimens measure: 

Length 21,. diam. 12.8, aperture 11.8 mm., whorls 5. 

Length 20.8 diam. 12, aperture 11 mm., whorls 5. 

Length 19, diam. 11.8, aperture 11 mm., whorls 5. 

Length 18.5, diam. 10.5, aperture 10 mm., whorls 4%. 

Length 17, diam. 10.5, aperture 10 mm., whorls 4%. 

A few examples among these shells are typical recta. 
Probably a collector who would keep his shells from different 
colonies separate would find that there are several races on 

3&. P. STRIGATA RECTA Pease. PI. 30, figs. 9, 10. 

The shell is openly umbilicate, acutely long-ovate, solid, the 
typical form white under a very thin, very pale green cuticle, 
which is often deciduous on the last half whorl. The spire is 
straightly conic, whorls S 1 /^ convex, the last one equably 
curved from suture to base. The initial half whorl is smooth, 


next two whorls of the embryonic shell are rather 'Coarsely 
pitted in spiral lines, following whorls marked with fine 
growth-lines and very fine spiral striae, most distinct at the 
base. The aperture is oblique, ovate ; peristome ~broad, white 
flatly reflexed, thickened within except near the upper angle. 
Length 21.5, diam. 12.5, aperture 12 mm.

4. P. BELLULA Hartman. PL 30, figs. 17, 18, 19. 

The shell is rather narrowly umbilieate, ovate-conic, thin, 
covered with a very pale olive or greenish-yellow cuticle with 
inconspicuous darker streaks, the embryonic whorls pale 
flesh-tinted. Surface somewhat shining, with sculpture of 
fine spiral striae which are crowded and wavy on the base, 
but separated by spaces much wider than the impressed lines 
on the upper part of the last whorl. 2% embryonic whorls 
(fig. 19) have the coarse pitting of other Marquesan species. 
Spire short, straightly conic ; whorls 4%, moderately convex, 
the last inflated, almost equably convex, but the base is es- 
pecially so. Aperture oblique, ovate; peristome reflected, 
gray, in fully adult shells having a narrow white callous rim 
at the inner edge, not extending to the upper termination of 
the outer lip. Columellar lip dilated. 

Length 14.2, diam. 9.7, aperture 8.5 mm., (type) . 

Length 16, diam. 9.9, aperture 9 mm.

203, fig. in text (Sept. 1, 1885 ) .GARRETT, Bull. Soc. Malac. 
France iv, 1887, p. 27. 

This species is more slender than P. decussatula, with a 
smaller aperture, and the spiral striation is much less crowded 


on the upper half of the last whorl. The type specimen (no 
4264 Carnegie Mus.) is not completely mature, wanting the 
narrow callous inner rim of the peristome, 'but there are 
several fully adult shells with younger ones in the collection 
of the Academy, taken 'by C. D. Voy. An egg shaken from 
one of them is very shortly oval, 3 x 2.5 mm., matt white, and 
smooth under an ordinary lens. 

5. P. DECUSSATULA (Pfeiffer). PI. 31, figs. 1, 4. 

Shell perforate, ovate-conic, thin, very minutely decus- 
sated with growth-lines and spiral striae, slightly shining, 
fulvous-whitish, diaphanous. Spire short, conic, rather ob- 
tuse. Suture moderate. Whorls 4%, convex, the last five- 
ninths the total length, rounded. Golumella subplicate, reced- 
ing. Aperture angularly oval. Peristome simple, thin, the 
margins converging, right margin with a bell-like expansion, 
columellar margin reflexed over the perforation. Length 15, 
diam. 8%, aperture 9 x 6% mm. (Pfr.)

A thin, inflated species, yellowish-corneous slightly brown 
tinted towards the summit, with a pale border below the 
suture denuded of cuticle, and a narrow very faint brown 
band just below the periphery. This band is sometimes very 
inconspicuous. Old shells lose much of the cuticle, becom- 
ing whitish and opaque. The aperture is ample. The peris- 
tome is corneous, thin, well expanded but not thickened with- 
in except in quite old shells. Several examples measure: 

Length 16.5, diam 10.3, aperture 10 mm., whorls 4%. 

Length 15.3, diam. 10, aperture 9.9 mm., whorls 4%. 

Length 15, diam. 9.9, aperture 9.9 mm., whorls 4%. 

The sculpture of rippled spiral striae is particularly well 
developed in this species. 


6. P. MAGDALIN^E Hartman. PL 31, figs. 2, 3. 

The shell is rather narrowly umbilicate, globose, with a 
short, conic spire, thin, fragile; white with some 'corneous 
streaks under a very thin pale yellowish cuticle, which seems 
to be usually deciduous above the periphery on the last whorl. 
Sculpture of minute, close spiral striae much as in P. decus- 
satula, but weaker above the periphery. Embryonic whorls 
as in decussatula. Spire very short; whorls somewhat con- 
vex, the last very much inflated, prominent in the peripheral 
region, convex beneath Aperture oblique, ovate; peristome 
reflexed, gray, thin, just noticeably thickened within. 

Length 14.8, diam. 11, aperture 10 mm. 

Length 15, diam. 11, aperture 10 mm., whorls -4%. 

Length 14, diam. 10.3, aperture 9.3 mm., whorls 414.

fig. in text. GARRETT, Bull. Soc. Malac. France iv, 1887, p. 27. 

This very delicate snail is related to P. decussatula Pf r., but 
it is very much more inflated, shorter, with a narrower um- 
bilicus. Of the four examples' originally composing the type 
lot, one has been broken; the example figured by Hartman 
is also damaged by a hole in front (not shown in my figure 
of this specimen). Perhaps none of the specimens is quite 
fully mature, but it is evidently a very thin shell at any stage 
of growth. Figured from cotypes, no. 4263 Carnegie Museum. 


The Society Islands are wonderfully rich in Partulas. 
Both species and individuals are developed in profusion, and 
differentiation of form and color has been carried further 
than in any other island group, though there has been no 
great structural divergence. Probably all of the Society 
species are referable to two stocks, herein regarded as "sec- 
tions. ' ' These sections may be defined thus : 
I. Shell ovate, with short spire, composed of 4 to 4% whorls, 
very thin, fragile and subtranslucent ; color pale and 


simple; aperture ample, peristome expanded, not thick- 
ened. Section Leptopartula, species 7 and 8. 
II. Shell composed of more than 4% whorls, usually solid, 
with opaque coloring, but sometimes white ; lip thickened 
within. Section Partula, species 9 to 50. 
Up to this time we owe our knowledge of the distribution 
and variation of Society Island Partulse to Andrew Garrett, 
whose residence at Tahiti gave him unusual facilities for their 
study. In the following account I have quoted largely from 
his writings and except in a few cases, have accepted his esti- 
mate 01 the rank of the several species and races. In a case 
like this, where races in all degrees of differentiation abound, 
the rank to .be assigned to any given race is, in the last re- 
sort, a matter of opinion. The criterion of intergradation is 
often difficult of application, as where the racial divergence 
is expressed chiefly in slightly different tendencies of varia- 
tion. In Raiatea and Tahaa especially, there seems to be a 
good deal of intergradation between the races and so-called

The shell is ovate with short spire, and composed of few 
(4 to 4%) whorls; very thin, fragile and somewhat trans- 
parent, pale; aperture large, ovate; lip expanded, not thick- 
ened. Type P. arguta. 

Two species, the most fragile of the genus, compose this sec- 
tion, which is confined to Huaheine and Raiatea. 

7. P. ARGUTA (Pease). PL 24, figs. 14, 15. 

The shell is narrowly but deeply perforate, short, ovate, 
extremely thin, fragile, corneous usually with a faint buff tint, 
and imperfectly transparent. Surface rather glossy, marked 
with weak growth-lines and microscopic incised spiral striae 
which are weak on the last whorl but distinct and close on 
the spire. The spire is very short, conic; whorls 4, convex, 
the last evenly convex, globose. The aperture is somewhat 


oblique, more than half the total length, broadly ovate. The 
peristome is thin and expanded throughout, whitish- corneous. 
Outer lip equably arched, basal margin more strongly arcuate. 
Columellar margin reflexed and dilated above. Columella 
concave, bending towards the right above. Parietal film 
hardly perceptible. 

Length 13, diam. 8.1, length of aperture 7.7 mm. 

Length 12, diam. 8, length of aperture 7.5 mm. 

Huaheine: "The metropolis of this very fragile species is 
in the upper portion of a mountain ravine, on the west coast 
of Huaheine, where it is rather common on the leaves of low 
shrubs and ferns. It occurs much more rarely in a neighbor- 
ing valley south of its specific center. Mr. Pease's habitat 
1 Tahiti, ' as given in his list of Polynesian land shells, is 
decidedly wrong." (Garrett).

Though referred by Pease to the genus Bulimus, it is, never- 
theless, a true Partula. "The animal, which is viviparous, 
has very long, slender, ocular tentacles, long lance-pointed 
foot, and that portion of the animal occupying the whorls 
of the translucent shells is beautifully maculated with black 
and white spots on grayish yellow ground. The shell, which 
is very uniform in all its specific characters, may be readily 
distinguished by its very thin pellucid texture, ovate form, 
abbreviated spire, turgid body-whorl, uniform pale yellow- 
ish horn-color, thin, slightly expanded lip and large simple 
aperture." (Garrett). 

Pease gave the following description. Specimens received 
from him are before me. "B. testa ovata, tenuissima pel- 
lu<jida, membranacea, nitida, anguste umbilicata; anfr. iv, 
convexis, ultimo ventricoso, suturis impressis; apertura 


ampla, ovata ; labro simplici, reflexo ; pallide straminea. Long. 
13, diam 8% mill." 

8. P. TURGIDA Pease. PI. 24, fig. 16. 

The shell is shortly, openly rimate, not perforate, short, 
obliquely ovate, extremely thin, fragile, corneous, faintly 
tinted with pale -brown, slightly transparent. The surface 
is glossy, marked with growth-lines and minute, close, spiral 
striae. Spire very short, conic; suture marked with a fine 
white line. Whorls 4%, convex, the last very large, evenly 
swollen. Aperture oblique, broadly ovate, two-thirds the 
length of the shell. Peristome thin, narrowly expanded, the 
columellar margin dilated and flattened above. Length 17, 
diam. 11.6, length of aperture 11.5 mm. 

Raiatea: though widely diffused it is excessively rare.

This delicate shell is larger and more opaque than P. arguta, 
and differs in the non-perforating umbilical fissure. Garrett 
remarks that "Like P. clara and P. annectens, it appears to 
be gradually becoming extinct."

The typical group of Partula is restricted to the Society 
and Hervey Islands. Each island has its minor type of 
shell, except Moorea and Tahaa, which have Tahitian and 
Raiatean types respectively ; 'but the entire series is so closely 
interrelated that the named subgeneric divisions proposed by 
Dr. Hartman cannot be sustained. 

A small group of white, translucent species includes 

No. 9, P. hywlina Brod. Tahiti, Hervey and Austral 

No. 16, P. clara Pse. Tahiti. 

No. 17, P. attenuates Pse. Tahiti and Raiatea. 

No. 44, P. annectens Pse. Huaheine. 

These forms may have some exceptional means of distribu- 
tion, or they may be conservative stocks, which have altered 
little since the original radiation over the mountain ranges 
which are now islands. They approach the simply colored 
southwestern forms of Partula, such as those of the Solomon 
Islands, in appearance, and seem to be little- changed mem- 
bers of an old stock. 

The species are here treated in geographic order, as follows : 

1. Tahiti, species 9 to 17. 

2. Moorea, species 18 to 21. 

3. Raiatea and Tahaa, species 22 to 41, 8. 

4. Huaheine, species 42 to 44, 7. 

5. Borabora, species 45. 

6. Species of uncertain habitat, species 46 to 50. 

1. Partula of Tahiti. 

"On Tahiti; the largest island in the group, we find eight 
species only, six of which are endemic. One (P. clara), 
which has a limited range, 'appears to be gradually becoming 
extinct. Four species (P. filosa, nodosa, product a and stolida) 
are each restricted to a single valley. All the above species 
are well-defined, and exhibit but little variation. On the 
contrary, P. otalieitana, which has its centre of distribution 


in Fautaua valley, has spread all round the island, and is sub- 
ject to so much variation that no less than fourteen species 
have 'been proposed for the different forms, Two species 
(P. kyalina and attenuata) are common to other islands;, 
the former is found in the Austral and on one of the Cook's 
group ; the latter occurs on Raiatea, but does not inhabit the 
two intermediate islands. It is a noteworthy fact that, not- 
withstanding both species have spread nearly all round 
Tahiti, yet they have not developed a single varietal feature, 
but, on the contrary, are remarkably uniform in all their 
specific characters. 

' ' Here we have three species ranging round the island, and 
all subject to the same conditions of life, yet two have not 
shown the slightest tendency to depart from the typical forms, 
and the other, which is very variable in its metropolis, has 
developed many local varieties. The above facts, which are 
common to other species, seem to suggest that physical con- 
ditions are not the primary cause of variations, but that it is 
the operation of some unknown law." (G-arrett). 

Numerous forms of Tahiti and Moorea are sinistral. The 
species of all the other islands are invariably dextral. Sin- 
istral Partulse also occur in the Samoan group. 

9. P. HYALINA Broderip. PL 24, figs. 10, 11, 12, 13. 

The shell is perforate, acutely long-ovate, thin but rather 
strong, corneous-white or bluish-white throughout. The 
spire is straightly conic, apex acute. Whorls 5, weakly con- 
vex, the last convex, becoming somewhat compressed laterally 
in the last half, base convex. Sculpture of fine growth-lines 
decussated by minute, close spiral incised lines. The aper- 
ture is very oblique, ovate. Peristome rather broadly re- 
flexed, strongly thickened within, the columellar margin 
weakly nodose.

Quite distinct 'by its milk-white color, and the very oblique 
aperture, contracted in adult shells by a strong inner rib of 
the lip. It might form a separate subgenus. 

The distribution of this snail on several widely separated 
groups is remarkable. Such distribution is unparalleled by 
any land snail of its size in Polynesia. I have not seen 
specimens from Mangaia or Rurutu, but those collected by 
Voy -at Rarotonga seem indistinguishable from Tahitian ex- 
amples. It seems possible that it has been distributed by hu- 
man agency, since it is not likely that a snail of this size could 
be carried far over sea by hurricanes, 'as the minute forms 
(Tornatellina, Pupidce etc.) no doubt have been. Still an- 
other hypothesis : P. hyalina may be an ancient and 'conserva- 
tive stock, which has survived from the time when these 
mountain islands formed the sierras of a larger land mass. 

10. P. COMPRESSA 'Pfr.' Reeve. PI. 41, figs. 19, 20, 21. 

"Shell acuminately oblong, rather thick, obliquely pro- 
duced towards the base, rather largely, compressed umbili- 
cate. Whorls convex, obliquely striated, very slightly 
spirally lineated ; last whorl rotundately angulated at the base. 
Aperture oblong, lip reflected in a slanting direction, a little 
contracted in the upper part. Dark chestnut brown, lip 
and interior of the aperture livid purple." (Reeve). 

"Shell deeply rimate, ovate-conic, rather solid, under the 
lens very minutely decussate; chestnut colored. Spire conic, 
rather obtuse; suture marked with a white line. Whorls 5, 


nearly flat, the last as long as the spire, narrowed and com- 
pressed at the base. Columella subnodose. Aperture oblong, 
narrowed by the calloused lip ; peristome brownish violaceous, 
broadly expanded, a little reflexed. Length 22, diam. 10, 
aperture with peristome 12x8 mm." (Pfr.)

The descriptions of Reeve and of Pfeiffer are given above. 
The type specimen is represented by fig. 21, 'copied from 
Reeve who described the species in advance of Pfeiffer. The 
figure measures about 24 mm. long. The last whorl is dark 
chestnut colored. 

Three specimens received as P. compressa from Mr. Cuming 
in 1862 are before me, two being figured, pi. 41, figs. 19, 20. 
The shell is glossy, with very fine and rather weak spiral 
striation. The color in one shell is white under a yellow 
cuticle, closely streaked with olive-yellow, the streaks form- 
ing an ill-defined median belt. The other specimens are very 
finely, 'closely but irregularly streaked with brown, on a 
yellow ground on the last whorl, giving a rather bright red- 
dish or yellowish brown appearance, while the spire is dull 
or liver brown, the apex dull purplish-brown. The last 
whorl is very conspicuously compressed laterally, flat there 
in the last half-whorl. The aperture is diagonal, the base 
thrown out from the middle, in the type figure and in the 
yellow shell before me (fig. 19), but in a smaller shell it is 
normal in shape. The lip is reflexed, heavily thickened 
within. The interior is white. 

Length 21, diam. 11%, aperture 12 mm., whorls 5%. 

Length 19%, diam. 10%, aperture 10.2 mm., whorls 5%. 

These specimens agree perfectly with one received from 
Andrew Garrett as P. stolida, and which he figured in Journ. 
A. N. S. Phila. ix, p. 70, pi. 3, fig. 58. I have drawn this 


shell somewhat enlarged on pi. 25, fig. 7. It has some re- 
semblance to P. affinis, but the last whorl is far more com- 
pressed laterally than in affinis. The spire is reddish-brown, 
becoming darker towards the apex, which is blackish-purple. 
The last whorl is olivaceous-chestnut, closely streaked with 
yellow. The last half of the last whorl is strongly com- 
pressed at the side, with a very convex, "saccate" base. The 
umbilical crease is rather ample. The rather narrowly re- 
flexed lip is fleshy-tinted, thin-edged, having a strong in- 
ternal thickening. No parietal tooth. Sculpture consists, 
of very fine and close spiral striae crossing the growth- 
wrinkles, and continuing to the lip. This shell measures, 
length 19, diam. 11, length of aperture 10 mm. Garrett 
writes: "I took a few examples of this ground species about 
two miles up Papenoo valley, on the northeast coast of Tahiti. 
They were all found lurking among the roots of ferns." 

The identity of the original P. stolida of Pease is doubt- 
ful. There is little in the description to exclude it from 
P. compressa, yet the statement that it is "dentate" prob- 
ably indicates that what Pease originally had was a form 
closer to P. affinis (no. 11&.) 

11. P. OTAHEITANA (Bruguiere). PI. 26, figs. 13-15; pi. 28, 
fig. 13. 

"This species is fluviatile and was discovered during the 
same voyage as the preceding [Captain Cook's], in the brooks 
of the island Otahiti. The shell is sinistral, oblong, oval, 
very thick, not more than 10 or 11 lines in length by about 
6 in diameter. It is composed of 5 whorls, united exteriorly, 
and as much swollen -as those of the austral Bulimus, but 
coiled in a direction contrary to that of most shells; that is 
to say, the right side of its animal is towards the left. The 
spire is conic and terminates in a pointed summit. The 
sutures resemble those of the preceding species [P. faba]. 
The 'aperture is semi-oval, oblique, rounded at the base, only 
a third longer than wide, and shorter by a line than half 
the shell. Outer lip arcuate, much reflexed iand recurved to 


the exterior, flat and projecting outside. The inner 
[parietal] lip is very thin and furnished with a tooth in the 
middle, only found in old shells, the young having an in- 
conspicuous callus in its place. The columella is simple, out- 
wardly covering an umbilicus resembling that of Bulimus 
australis. The whole shell is brown outside, or the color of 
roasted coffee; the lips are whitish and the cavity sooty. 
It is not eommon. ' ' (Brug.).

Bruguiere's account is given above, since it seems to indi- 
cate a darker, more elongate shell than that generally ac- 
cepted as typical otaheitana. 

"The metropolis of the typical otaheitana is about two 
miles up Fautaua valley, on the northwest part of Tahiti, 
where it is very abundant on the trunks and foliage of trees 
and bushes. The above-mentioned valley being close to the 
principal harbor which was frequented by the early naviga- 
tors, it was undoubtedly where Bruguiere's type was ob- 

' ' The Fautaua shells, which are very variable in size, shape, 
and color, are never ornamented by spiral bands, and about 
one-third of the specimens are sinistral. The parietal tooth 
is nearly always present in the adults, and the peristome, 
though usually white, is frequently pinky flesh-color. The 
prevailing colors are straw-yellow, reddish fulvous, light 
chestnut, frequently with the spire more or less tinted with 
reddish and often with longitudinal strigations. The spire 
is more or less produced, and the aperture varies some in size 
and shape. 

"The shape of the shell varies from abbreviate-ovate to 
elongate-ovate, as the following measurements will show: 
Length 21, diam. 10 mm. Dextral specimen. 
Length 16, diam. 10 mm. Dextral specimen. 


Length 20, diam. 10 mm. Sinistral specimen. 

Length 16, diam. 9mm. Sinistral specimen." (Garrett). 

The following form has been referred to otaheitana as a 
synonym by Garrett and Hartman. "Bulimus isabellinus 
Pfr. Shell subperforate, oblong-conic, solid, striatulate, isa- 
belline. Spire conic, rather acute. Whorls 5, a little con- 
vex, the upper sculptured with impressed, very delicate spiral 
lines, the last, a little shorter than the spire, base rounded 
in front. Columella white, plicate-gibbous. Aperture ob- 
long-oval, narrowed by a dentiform callus deep within on 
the belly of the penultimate whorl. Peristome callous, white, 
broadly expanded, a little reflexed, the columellar margin 
dilated, sinuous-reflexed. Length 22, diam. 10, aperture in- 
side 9 mm. long, 4% wide. Habitat unknown, Mus. Cuming. ' ' 
(Pfr.) Reeve's figure is -copied, pi. 26, fig. 16. 

P. l&vigata Pfr. is doubtless a Society Island shell, prob- 
ably a form of P. otaheitana. The description follows : 

P. Icevigata Pf eiff er. ' * Shell deeply rim-ate, ovate-conic,, 
solid, smooth, (slightly striatulate under the lens), glossy, 
buff. Spire conic, rather obtuse; suture moderate. Whorls 
5, a little convex, the last about equal to the spire, more 
swollen next the suture, rounded at base. Columella in- 
wardly nodose-plicate above the middle. Aperture slightly 
oblique, oblong, obstructed by a deeply placed tubercle on 
the penultimate whorl; peristome thick, white, spreading 
throughout, the columellar margin dilated and adnate above. 
Length 20, diam. 10 mm.; aperture with peristome 11 mm. 
long, 4 wide inside. Habitat unknown (Cuming coll.)."

110. P. o. LIGNARIA Pse (pi. 25, figs. 1, 2, 3, 4.) "In a 
valley about two miles west of Fautaua, there exists in abund- 
ance the variety ( ?) lignaria, Pease, which, though described 
as dextral, is nevertheless very frequently sinistral. Though 
not attaining quite so large a size as the Fautaua shells, it 
differs none in shape, but is usually darker colored and 


more strigated, as well as exhibiting one to three transverse 
reddish chestnut bands. The lip is always white, and the, 
parietal tooth is very seldom 'absent. The inosculation with 
otakeitana is so complete that it cannot be even separated as 
a well-marked variety." It was thus described: Partula 
lignaria Pease in Proc. Zool. Soc. 1864, p. 671. " P. t. ovata, 
solidiuscula, dextrorsa, anguste umbilicata, sub lente minu- 
tissime transversim striata, irregulariter longitudinaliter 
striata; anfr. 5, plano-convexis, sutura impressa; apertura 
rotunda to-ovata, edentata, labro rotundatim incrassato; cas- 
taneo-fusco irregulariter longitudinaliter strigata, interdum 
omnino ruf o-f usca. Long. 18, diam. 10 mill. ' ' 

"Var. &. Fascia unica nigro-fusca cingulata, seu omnino 
flavide fusca." 

Grarrett's note on this imperfectly differentiated race is 
given above. The figures are from shells collected by him, 
showing several color-patterns. In certain examples a more 
or less conspicuous nodule appears on the face of the colu- 
mella near its insertion, fig. 4, much as in P. auriculata and 

Dr. Mayer found lignaria streaked without spiral bands, 
and also with one dark peripheral band in Tipaerui valley. 
All were dextral. In a few there is an additional subsutural 

In Hamuta and Pirge Valleys, a form with sutural, peri- 
pheral and umbilical bands was found, constituting 3 to 4

"Observations: The above species is allied to P. otaheitana. 
It is, however, smaller and less elongate." (Pease). 

Garrett writes: " Pease's affinis, which cannot be separated 
from some of the small abbreviated forms of otaheitana, oc- 
curs in greater or less abundance in all the valleys from 
Haona as far as the southeast end of Taiarapu peninsula, 
and round the opposite coast as far as Papieri on the 'south- 
west of Tahiti proper. In Papinoo I discovered a large 
colony of affinis, many of which had the pinky flesh-colored lip 
and sinistral form of otaheitana. Far up in the same valley, 
though common, none but dextral forms were found, and out 
of thousands taken in the other valleys, not one sinistral ex- 
ample occurred to my notice. 

Three examples of affinis, received from Pease, and rep- 
resenting the three color-forms mentioned by him, are fig- 
ured, pi. 25, figs. 5, 6, 9. All the examples of this lot have 
the parietal wall dentate. The sculpture of spiral lines is 
very fine and close, but on the last whorl it is more or less 
obsolete, especially so in the middle of each whorl. 

In a lot of five examples received from Garrett, one has 
a small parietal tooth, the others none. All are obscurely 
streaked with chestnut on a yellow ground, the spire brown. 
The sculpture of the latter part of the last whorl below the 
suture, of one of this lot, is drawn in pi. 25, fig. 8. In some 
other individuals, the spiral lines are subobsolete, as in 
typical affinis.

"In a valley several miles from Papinoo I found a small 
colony of affinis which were marked by three transverse red- 
dish chestnut bands like lignaria. And most singular, no 


other banded specimens of affinis occurred to my notice in any 
other part of the island. This is the variety dubia Pse., by 
Carpenter erroneously referred to varia." [PL 25, fig. 10, 
11]. The var. dubia was not defined by Pease, but only 
mentioned as a form of varia, in P. Z. S. 1864, p. 675. Its 
first published definition was in Garrett's note, quoted above. 
Examples of dubia from Pease are figured (pi. 25, figs. 10, 
11) . The smallest dubia seen are only 15 mm. long.

"Shell sinistral, subperf orate, ovate- turrite, rather solid, 
striatulate, glossy, citrine, the acute apex reddish, suture 
white-edged. Whorls 5, the upper flat, the rest convex, the 
last shorter than the spire. Columella nearly simple, slightly 
plicate. Aperture oblong-semioval. Peristome somewhat 
thickened, white, expanded and reflexed, the columellar mar- 
gin wide, flat, spreading. Length 23, diam. lli/, aperture 
inside 9% mm. long, 5 wide. A variety is somewhat smaller, 
ornamented with wide blackish-chestnut bands, the peristome 
livid-brown." (P/r.). 

"To the eastward between Fautana and Papinoo valley, a 
distance of about eight miles, there are three valleys, all in- 
habited by Pfeiffer's amabilis, a sinistral form which has 
not a single feature to distinguish it from some of the large 
turreted Fautaua shells. In the first valley, Pfeiffer 's species, 
though not abundant, were very fine specimens. The next 
valley, known as Pirai, (the metropolis of the small dextral 
P. filosa, which occupies the lower part of the valley), is, in 
the upper part, which trends towards 'the headquarters of 
otaheitana, inhabited by the sinistral amabilis. A few im- 
mature examples were found which were 'banded like lignaria. 
The only dextral Partula taken in the two valleys were 
filosa, attenuata and hyalina. 

"In the next valley, called Haona, I found the dextral 
P. affinis abundant, and took a few of amabilis. 

"Both Dr. Pfeiffer and Reeve described the latter species 
from specimens in the Cumingian collection, and both quote 


Anaa, a low coral island, as its habitat. Having resided 
about five months on that island, and searched all parts for 
shells, I did not find a single Partula there, or on any other 
low coral island. Though neither Pfeiffer nor Reeve allude 
to a parietal tooth, it is very frequently present. " ( Garrett)

Fig. 4 is a copy of Reeve's. The examples before me are 
the form sent out as turricula by Pease. They are all sinis- 
tral, elongate, glossy, varying from chestnut-tinted yellow to 
pale yellow with light green streaks on the last two whorls, 
those preceding rose-tinted, the shade deepening to the apex. 
The lip is white in the paler shells, rose-tinted in the darker. 
Measurements vary from length 22, diam. 12.1, aperture 10.9 
mm., to 19, 11, 9.8 mm. just three-fourths of the adult shells- 
seen have a parietal tooth. Garrett writes: " Reeve's rubes- 
cens is abundant in Papinoo, and occurs sparingly in all the 
valleys as far as the southeast end of the island. Like ama- 
bilis it cannot 'be separated from the sinistral turreted ota- 
heitana, inhabiting Fautaua. It is always sinistral, never 
banded, and, though usually of a reddish tint, is frequently 
straw-yellow or fulvous, with or without a reddish or pinky 
apex. The lip is white or pinky flesh-color. Though de- 
scribed as edentate, some have a small parietal tooth. Reeve 
gave no locality, and Pfeiffer erroneously cites the Marquesas 
as its habitat." 

lie. P. o. SINISTRORSA 'Pse.' Garrett. PI. 26, figs. 7, 8, 9, 10. 

" Pease's siwistrorsa is confined to the south coast of Tahiti 

proper, where it exists in the greatest profusion in all the 


valleys and lowland forests for a distance of ten or twelve 
miles. In the valley which is the limit of the range of the 
dextral a/finis I took several specimens of the sinistral sinis- 
trorsa. The latter is invariably reversed, dentate or eden- 
tate, fulvous with three more or less diffused reddish chest- 
nut bands. Reeve figures the same shell on Plate 3, fig. 13a, 
as otaheitana. Bandless varieties are frequent, and vary 
from straw-yellow to fulvous or light chestnut, frequently 
.strigated and the lip white. The latter varieties differ none 
from the true otaheitana of Fautaua. 

" It is worthy of remark that in that part of the district of 
Papieri, occupied by sinistrorsa, is also the headquarters of 
the terrestrial P. producta, a dextral species, which is always 
edentate, and exhibits the fasciation of the former. 

' * After passing to the westward of the range of the typical 
sinistrorsa, which presents the same features for a distance 
of ten or twelve miles, it suddenly exhibits a tendency 'to a 
change in its becoming more stunted, more solid, always den- 
tated, and the bands, one to three, are sharply defined on a 
pale ground. It is the sinistralis of Pease, MS., and occupies 
two valleys. 

''In the next large valley, called Faahuaite, on the south- 
west coast, we find Pease's crassa (MS.), which is also a sin- 
istral shell, always dentated, solid, more tightly coiled than 
sinistrorsa, and the body-whorl is more flattened. It is rarely 
marked by a single narrow submedian chestnut band. In the 
same valley, but more inland, occurs a smaller form, which is, 
I suppose, the P. brevicula, Pse., MS. [see pi. 26, f. 12, speci- 
men from Dr. Hartman]. 

"The following valley, named Punaavia, is the metropolis 
of the beautiful P."* nodosa, which also exhibits three bands. 
Far above the restricted range of 'the latter, where the valley 
turns towards the head of Fautaua, the home of the typical 
otaheitana, I took a few examples of a Partula, similar to, but 
larger than crassa. The next valley is the habitat of 
lignaria. ' ' ( Garrett ) . 

Specimens of sinistrorsa received from Pease and Garrett 


are figured. There is also a 'bandies form, dark chestnut 
colored with darker and lighter oblique streaks, which may be 
called variety confiuens (pi. 26, fig. 11).

In my copy of Pfeiffer 's figure (pi. 27, fig. 13) the small 
parietal tooth was omitted by oversight. It is very indis- 
tinctly drawn in the original figure, and should resemble that 
of fig. 9 of the same plate. 

P. stenostoma was not identified by Mr. Garrett. The 
positions of the bands cause me to think it related to affinis 
Pse., and dubia Garr., but it differs from these and other 
forms of P. otaheitana by the narrow shape of the aperture. 
Dr. Hartman has referred stenostoma to P. vexillum Pse.; 
and it has a certain resemblance to the Raiatean P. planila- 
brum and P. vittata.

the middle band widest, the lower one defining a light umbili- 


cal patch.; whorls of the spire showing two dark bands on-a 
light or flesh-colored ground, apex dark. The surface shows 
no spiral lines, or only faint traces of them. Whorls 5%,

beneath. The aperture is nearly vertical, dark within ; peris- 
tome narrowly expanded and reflexed, moderately thickened

This terrestrial form was found by Garrett to be invariably 
dextral. It is not so glossy as P. otaheitana sinistrorsa Pse., 
but otherwise there is not much difference. P. producta how- 
ever has somewhat diverse variations; the dark bands be- 
come confluent in some individuals by darkening of the 
ground color, leaving the last whorl chestnut with (usually) 
a pale sutural band and umbilical patch. Garrett also re- 
cords a mutation uniform pale fulvous or tawny with a darker 
apex. Description and figs. 1, 2, 3 from examples received 
from Pease.

at the suture, and often some other pale bands. Spire conic, 


acute. Whorls 5%, a little flattened, the last about as long 
as the spire. Columella plicate above, deep within, then 
nodulose. Aperture subvertical, oblong, narrow; peristome 
outwardly scarcely expanded; inwardly provided with an 
acutely projecting white callus, contracting the aperture;

Tahiti: "This beautiful arboreal species is restricted to a 
limited area about two miles up Punaavia valley on the west 
coast of Tahiti. I first discovered the location in 1861, and 
gathered about three hundred examples. On a subsequent 
visit, nine years later, I secured over eight hundred speci- 
mens. It is entirely confined to the south side of the stream 
which flows through the valley, and circumscribed in a nar- 
row area about three-fourths of a mile in length. ' ' ( Garrett) .

P. nodosa stands near P. suturalis of Moorea, which doubt- 
less arose from the same ancestral stock. In Tahiti it has no 
little resemblance to certain forms of P. lignaria, especially 
those with many streaks and a single dark belt, many of 
which show a more or less developed nodule on the columella, 
such as is characteristic of P. nodosa. 

The typical P. nodosa, pi. 25, figs. 12, 13, was the dark 
reddish-brown or chestnut-brown shell, with a wide cream- 
white band below the suture on the last one or two whorls. 


There is usually more or less pale streaking of the dark 
ground on the last whorl; the reverse of the lip and the 
border of the umbilicus are also pale. Several examples seen, 
one of them received from Dr. Pfeiffer. All are dextral. 
Judging 'by the lots before me, this form occurs in the same 
colonies with the following color phases. 

Color-form TRILINEATA Pease. PL 25, figs. 14, 15. "Cream 
color or yellowish horn-color, the spire usually reddish-brown, 
last whorl striped irregularly with brown, and encircled by 
three dark reddish-brown lines or bands ; suture margined 
with white "(Pse). In the typical lot of trilineata received 
from Pease the spire is fleshy brown in two examples (typical 
coloration) ; clear corneous in two; -and the other two have 
some whitish and faint brown markings on a fleshy-corneous 
ground. Four of the shells are 3-banded, like fig. 14, 15, one 
has only a wide chestnut belt, and is conspicuously streaked 
with brown, and the sixth is a typical nodosa in color. 

A lot from Barrett consists of (1) ordinary dark P. nodosa; 
(2) one sinistral shell (fig. 16) with normal trilineata color- 
pattern. Garrett states "about one in two hundred is sinis- 
tral ") ; and (3) pale shells with the spire corneous, last iy 2 
whorls cream-colored with a profusion of corneous and cor- 
neous-brown streaks which do not reach to the suture; aper- 
ture typical (pi. 25, fig. 17, color-form pallidior). 

14&. P. N. LJEVA, n. n. PL 25, figs. 18, 19. 

* * The shell is blunt in shape and the spire is short ; the lip 
is quite thick, and is usually provided with a well-developed 
tooth upon the columellar side, and there is also a tooth upon 
the wall of the aperture. The surface of the shell is smooth 
and slightly polished, and there are no deep longitudinal fur- 
rows. About 57 per cent of these snails are well represented 
by fig. 18. The ground color is a light horny-yellow streaked 
longitudinally with darker brown, in addition to which there 
are two dark-brown whorl-stripes and a white whorl-stripe 
adjacent to the suture of the spire. In about 43 per cent 
the dark-brown whorl stripes are either absent or very faint, 


and the ground color of the shell varies from light horny- 
yellow to rich brown. A snail of this type is fairly well rep- 
resented in fig. 19, a dark-brown individual being drawn. 
Ninety-seven per cent of the adult snails of type 18 and 91 
per cent of type 19 are sinistral ; while of the young, 100 per 
cent from type 18 and 90 per cent from type 19 are sinistral. 
In the ease of the snails of type 19, twenty-six sinistral adults 
gave forty-six sinistral and one dextral young ; while two dex- 
tral adults gave four dextral and no sinistral young. Among 
the snails of type 18, only one of the dextral adults con- 
tained young and this one gave a single sinistral offspring. 
Twenty- six whorl-striped adults of the type of fig. 18 gave 
forty-two young, of which 76 per cent display whorl-stripes,, 
while 24 per cent are plain colored. On the other hand, 
twenty-eight adults of type 19, which are either unstriped 
or with very faint whorl-stripes, gave forty-one young of 
which 61.5 per cent are marked with whorl-stripes and 38.5 
per cent are plain colored. It is very evident that the 
striped and unstriped forms intergrade. 

"Of the one hundred adults found in the valley, 94 per 
cent are sinistral, while of the eighty-eight young taken from 
them, 94.5 per cent are sinistral. This condition appears, 
therefore, to be stable from one generation to another."

P. filosa is quite distinct from other Tahitian snails, but is 
very closely related to the Moorean P. nucleola Pse. It is 
a small, ovate, solid and compactly coiled shell, dull or with 
but little gloss, and either reddish-brown with darker pur- 
plish summit, or dull yellow with the summit roseate; in 
either case being irregularly marked with many backwardly 
sloping longitudinal whitish lines. Under the lens these lines 
appear ragged, and are seen to be due to the loss of cuticle 
along some of the lines of growth. All the post-embryonic 
whorls have this peculiarity. The spiral striation is well 
developed throughout. All of the thirty examples seen have 
a parietal tooth, but in some it is quite small. The peristome 
is white, moderately expanded but strongly thickened within. 
There is often the low indication of a tubercle on the colu- 
mella. No banded or sinistral examples have been found.

chestnut, often variegated with darker obliquely axial streaks ; 
suture with an opaque-white margin. Surface somewhat shin-

waved spiral striae. Whorls 4%, moderately convex ; the last 
half of the last whorl is noticeably compressed below the 
periphery, the base being strongly convex. Aperture ovate, 
.slightly oblique, usually pale brownish or fleshy inside. 
Peristome white, reflexed, thickened within except near the

This leaf -dweller is said by Garrett to be rare and in his 
opinion approaching extinction. It has the figure of P. 
annectens of Huaheine, but is much less delicate. P. attenuate 
of Raiatea and Tahiti, is an allied species of much more 
slender contour. 

Specimens from Pease and Garrett before one are either 
nearly uniform in tint, or streaked obliquely with chestnut. 
Pease in his original account has described a ' ' var., encircled 
with a single line, or two or three." Garrett describes it as 
'" corneous, sometimes with darker stripes, and more rarely 
with one or two transverse chestnut bands. ' ' In being varie- 
gated, P. clara is clearly less modified from the ancestral stock 
than P. attenuata and annectens. 

17. P. ATTENUATA Pease. PI. 24, figs. 1, 2, 3, 4. 

The shell is openly perforate, slender, long-ovate, thin, 
slightly pellucid pale yellowish-corneous, sometimes with a 
faint reddish tint towards the apex; the suture transparent- 


margined, or margined with a white line. Surface lustrous, 
faintly marked with growth lines and minute, crowded, finely 
rippled spiral striae throughout. Whorls 5, but slightly con- 
vex, the last one compressed below the periphery, and strongly 
convex, somewhat swollen, at the base. (This is well shown 
in fig. 2). The aperture is nearly vertical, more than half 
the total length. Peristome broadly reflexed, the basal and 
outer margins thickened within except near the upper end 
of the lip, which is thin and merely a little expanded. Colu- 
mellar margin dilated and bifurcate above. Parietal callus, 
a transparent film.

Society Islands: "Upper portions of all the central val- 
leys on both the east and west sides of Raiatea. It is more 
abundant in Toloa and Hapai valleys than elsewhere. Owing 
to its peculiar habit of living on the foliage near the tops of 
trees, it easily escapes observation. It occurs more rarely at 
Tahiti, where it has, also, a wide range, and is confined to 
the upper portions of the valleys." (Garrett) .

This snail is closely related to P. annectens of Huaheine, 
having in common with that the color, texture and sculpture, 
and especially the peculiar shape of the last whorl, which is 
compressed below the middle, then swollen around the umbili- 
cal region in both species. It differs from annectens by its,, 


more slender shape, heavier substance, and wider lip, which 
is calloused within. P. clara also is an allied species of 
broader contour, but with an aperture much like that of 

In a lot 01 three specimens sent many years ago by Pease, 
the suture has a grayish margin ; but in all other shells seen, 
the margin is white, by loss of the cuticle, or by its becoming 
permeated with air. Normally the lip-edge and parietal 
callus are thin, but in one very old shell before me, 'both are 
considerably thickened. 

Pease described this species twice, evidently from the same 
examples. He seems to have forgotten the description of 
1864. It is an error other prolific authors have committed. 

"When we take into consideration its peculiar habit of 
concealment in the tops of trees, and its range restricted to 
the more elevated portions of the valleys, so contrary to the 
habits of other species, it is really remarkable to find it in- 
habiting two remote islands, especially as all the other species 
have a very limited range. It does not occur at Tahaa, which 
is only four miles from Raiatea, and enclosed in the same en- 
circling reef. It is no less singular to note its absence from 
Huaheine and Moorea, though at the former island we find 
the closely allied P. annectens." (Garrett). 

2. Moorean Partulcz. 

Four species and numerous subspecies are peculiar to 
Moorea, which is separated from Tahiti by a channel only 
eight miles wide. All show clear traces of a common ancestry 
with Tahitian forms, though since the separation of the islands 
there has been specific divergence. The affinities of the snails 
are as follows : 

Tahiti. Moorea. 

P. otaheitana P. mooreana 

P. nodosa P. suturalis 

P. filosa P. taeniata group. 

18. P. MOOREANA Hartman. PL 29, figs. 17-20. 

The shell is sindstral, deeply but shortly rimate, rather thin ; 


dilute yellow, fleshy-corneous or soiled white, the first whorl 
almost always -brown; rarely the last whorl is streaked with 
buff (fig. 19), or has three pale brown spiral bands (fig. 17). 
Surface shining, rather densely marked with spiral striae 
throughout. Spire straightly conic; whorls 5, only very 
slightly convex, the last compressed laterally, convex below. 
The aperture is quite oblique, peristome is well reflexed, 
strongly thickened within, much narrower in its upper third. 
Columellar margin dilated at the insertion. There is usually 
a rather thick but transparent parietal callus and a well- 
developed parietal tooth. Length 18.5, diam. 11, length of 
aperture 10 mm.

P. mooreana "may be characterized by its elongate-ovate 
form, rather thin texture, constant parietal tooth, planulate- 
conical spire, which equals half the length of the shell, pale 
luteous color, with darker apex. It is always sinistral, and 
the white expanded lip is rather thin and moderately incras- 
sated. A variety with three narrow pale brown revolving 
bands is not infrequent. 

"It is closely related to some of the sinistral forms of 
varieties of P. otaheitana, particularly with Pease's P. crassa, 
which, though of the same shape, is more solid, rougher, and 
the fine crowded spiral incised lines which extend over the 
whole surface of the former are nearly obsolete on the latter. ' '

10, 11. It was described from the Cuming collection, the 
habitat being unknown. Dr. Hartman seems to have first re- 
cognized it in the common Moorean shell under considera- 
tion. Garrett subsequently (1884) discussed the species at 
great length. 

Figures 5, 6, 8 of plate 28 represent the typical form of 
the species. The shell is rather solid when adult, compact in 
shape. The lip is snow-white, thickened within, columella 
vertical, swollen or inflated just below the insertion. There 
is generally no parietal tooth, but when developed it is a low 
callous node or pad, not often a distinct tooth, as in vexillum. 
The first 2% whorls are isabella-colored ; the darker o'b- 
liquely longitudinal stripes appear at first rather faint and 
widely spaced on the isabelline ground, but on the last whorl 
the ground becomes opaque, more or less cafe-au-lait tinted or 


sometimes nearly white, and the stripes are 'brown-corneous or 
even, unequal and unevenly spaced. The sculpture consists 
of spiral incised striae which are rather widely spaced, and 
typically are distinct on the last whorl. 

This type of shell is further modified by the development 
of spiral bands; sometimes only one, at the periphery, the 
base of the shell often chestnut-colored, and again two bands, 
one above, the other below the periphery (pi. 28, fig. 8; pi. 27, 
fig. 6). Specimens with oblique streaks only, with one and 
with two bands, occur together in Grarrett's sendings, and 
apparently are mingled in the same colonies. The spiral 
striation is usually subobsolete on the upper part of the last 
whorl in these shells, which are what Pease named in MS. and 
Smith described as P. alternata. The preceding forms are 
what Garret t alludes to as found in Oahumi valley. Com- 
paring this race with vexillum, he writes: ''The Oahumi 
shells are usually a trifle smaller, not so frequently dentated, 
and are much more conspicuously strigated than the Vaianai 
shells. The spiral bands, of which there are one or two, sel- 
dom three, on the body- whorl, are very frequently interrupted, 
which, with the conspicuous strigations, gives the shell a some- 
what tessellated appearance. All the color- varieties alluded 
tOjin my remarks on the Vaianai shells are also found in 
Oahumi, but the uniform dark-colored ones are more fre- 
quent, besides one of a uniform white color, not decorticated, 
of which I took three examples. 

1 'So far as I can ascertain, there has been no figure pub- 
lished of Pfeiffer's strigosa. He gives the Admiralty Islands 
as its habitat. There are no species of the type he describes 
found in the western Pacific. It is undoubtedly a Society 
Islands species, and I fully agree with Dr. Hartman in re- 
ferring it to the shells under consideration. ' ' 

Further Oahumi color-forms are represented in pi. 28, figs. 
1, 2, 3, 4, the lot from Garrett. They are chestnut with light 
streaks and a white suture, the spire flesh-colored (fig. 3), the 
same with a pale girdle (fig. 2), or line (fig. 1), at the peri- 
phery, or there may be two white zones, one below the suture, 
the other in the middle of the basal slope (fig. 4). 


P. strigosa Pfr. is probably, as Garrett and Hartman have 
held, a form of suturalis. It w*as described as follows : ' ' Shell 
perforate, oblong-conic, rather solid, very obsoletely decus- 
sate, subopaque; whitish, ornamented with irregular fulvous 
and rufous streaks. Spire conic, the apex acute. "Whorls 5, 
nearly flat, the last slightly shorter than the spire, somewhat 
tapering at the base, rounded. Columella somewhat twisted 
above, subnodose at base. Aperture slightly oblique, trun- 
cate-oval, generally contracted by a nodiform parietal callus. 
Peristome white, callous, subequally spreading throughout. 
Length 17 to 18, diam. 9 mm., aperture with peristome 8% x 
6% mm., inside 3% mm. wide. Admiralty Is." (P. strigosa 
PFR., P. Z. S. 1856, p. 384). 

19&. P. SUTURALIS VEXILLUM Pease. PL 27, fig. 9 ; pi. 28, figs. 

The shell is typically dextral, more lengthened than the 
preceding, less compact, and somewhat thinner. On a corn- 
eous-buff ground it is obliquely streaked with opaque buff 
on the last whorl, and begirt with two chestnut bands, the 
upper one ascending on the penult, whorl. Parietal tooth 
well-developed. Spiral striation wanting or extremely weak 
on the last whorl. Sutural white line inconspicuous or even 
wanting. Length 21, diam. 11%, length of aperture 11 mm. 
Description and fig. 9 are from one of Pease's original lot. 
Other shells are somewhat smaller, length 18 mm., and the 
oblique streaks may be less distinct. 

Many examples were collected by Andrew Garrett, who 
found it variable. Some shells are dark chestnut with a 
white sutural line (fig. 10) ; others are like Pease's original 
lot, or have a third band, around the umbilicus (fig. 11) ; 
while some shells are finely streaked brown and buff, without 
any bands (fig. 12) . Garrett writes as follows : ' ' This beau- 
tiful arboreal species is found in great profusion in Vaianai 
valley, on the southeast coast of Moorea, where it occurs in 
company with P. mooreana and P. elongata. It also exists 
in considerable numbers in a small valley about two miles to 
the westward, associated with P. tceniata and elongata. 


* ' I first discovered this species in 1861, and obtained several 
hundred specimens, all collected on the eastern side of the 
stream that flows through the valley of Vaianai. They were 
all dextral, and were so described by Pease, under the name 
of vexillum. On a second visit, in 1875, I took over 2000 ex- 
amples, all gathered on the western side of the stream, and 
was surprised to find many sinistral forms among them 
[pi. 28, fig. 9]. At the same time I found -about .a dozen 
specimens, all sinistral, in a large semicircular valley on the 
opposite side of the island. They were probably stragglers 
from Vaianai. 

"It is noteworthy that no reversed Partulce were found in 
any other part of the island except on the western side of the 
stream in Vaianai, and the above-mentioned stragglers taken 
on the opposite coast. The same side of the stream is also 
the home of the sinistral P. movreana."

The typical form is tawny brown with two widely separ- 
ated white bands as shown in figures 15, 16 of pi. 28. There- 
are also often some pale oblique streaks. The shape, as 
(iarrett writes, ' * varies from iabbreviate-ovate to elongate- 
ovate, more or less solid, scarcely shining, smooth or wrin- 
kled with incremental striae, and the spiral incised lines are 
very fine, and crowded on all the whorls. The spire is more 
or less produced half the length of the shell, sometimes 
shorter or a trifle longer. The last wjiorl is frequently com- 
pressed in the back and right side, which gives it a faintly 
biangular appearance. The peristome is more or less ex- 
panded, sometimes considerably so, moderately thick, slant- 
ing and labiated within. Columellar lip more or less tor- 
tuous, abruptly receding above, which gives it a nodulous ap- 
pearance. About one in a hundred exhibits the parietal 
tooth. The color is also variable : white, straw-yellow, lemon- 
yellow, light orange, corneous, fulvous, various shades of 
brown, sometimes with darker strigations, and frequently 
spirally banded. The most common style of fasciation con- 
sists of from one to four narrow, more or less broken, fulvous. 
or fulvous-brown bands on the body-whorl. Fulvous-brown 
examples, with two or three pale bands, are not so common. 
The last appears to be Moreh's type, which he incorrectly as- 
signs to the Viti Islands. ' ' 

11 The metropolis of this truly protean species is in a very 
large semicircular valley on the north coast of Moorea, where 
it occurs in prodigious numbers on the foliage of bushes. In 
the western part ol the same valley, where it exhibits less 
variation, it gradually intergrades with the form which has 
been distributed under the name of nucleola Pease, which 
has its headquarters in a small, but isolated, valley about 
two miles west of Opunohu. 


' ' On the southwest part of the island we find tczniata toler- 
ably abundant in three valleys, and, like the shells in the 
western part of Opunohu, it is subject to much less variation 
than obtains in the eastern part of the same valley. The 
shells from the southwest coast were described by Pease un- 
der the name of P. simulans [pi. 29, figs. 8, 12, 13]. 

"In the third or more eastern valley, where they come in 
contact with P. elongata and lineata, hybrids between the 
former and taniata are so numerous that any one collecting 
in that valley only would, without hesitation, pronounce them 
one and the same species. 

' ' From this point to a distance of several miles, the valleys 
are inhabited by lineata, mooreana, elongata and lineata var. 
strigosa, only. But -after passing Oahumi, the home of the 
latter variety, we again find tczniata, but nearly as variable as 
the eastern Opunohu shells, and mixed with the form known 
as striolata, Pse., with which it intergrades. Here I found 
several unmistakable hybrids between strigosa and t&niata. 
All the valleys between this latter location and the one near- 
est to Opunohu are inhabited by the typical form striolata, 
which scarcely differs from nucleola, except in being smoother, 
and more variegated with stripes. In a large valley adja- 
cent to Opunohu, we find these shells by thousands; they 
differ in being beautifully striped like strigosa. Here, again, 
it insensibly graduates into the typical t&niata. Whether the 
inosculation takes place through hybrids or not is a difficult 
question to decide. In looking over a large collection from 
the eastern part of Opunohu, I find some of the small forms 
are not dissimilar to the typical striolata, which has suggested 
the propriety of following Dr. Hartman in consolidating the 
three forms." (Garrett).

shorter. Columella obliquely subplicate above. Aperture

An example of P. spadicea received from Mr. Cuming in 
1862 is smaller than Reeve's figure, but resembles it in other- 
wise. Though labeled "Marquesas" it is apparently a form 
of P. elongata Pease, or very closely related to that species. 
Dr. Hartman has referred spadicea to P. tceniata; and the 
figure certainly has a close resemblance to P. simulans Pse., a 
form of t&niata. 

P. simulans Pease, based on shells which are "plain red- 
dish-brown yellowish or horn-color " or with "three inter- 
rupted transverse bands " belongs apparently to tceniata. 
PL 28, fig. 14 represents the cotype originally supplied by 
Pease for pi. 1, fig. 11 of the Am. Journ. Conch. It is not 
fully mature, and is corneous with indistinct brown streaks. 
It is this 'form which seems to be identical with P. spadicea 
Rve. PL 29, figs. 8, 12 are uniform white and brown-banded 
examples also supplied by Pease at the time of original pub- 
lication. The banded examples have two submedian and one 
umbilical band, on a corneous-whitish ground. Some of 
these shells scarcely differ from P. t. nucleola. 

P. striolata Pease, seems to be identical with t&niata ex- 
cept in coloration ; it is dull tawny-brown with a few whitish 
oblique streaks. The columellar tubercle is very weak, not 
prominent as in nucleola. Fig. 8, pi. 27, is draw!n from a 
cotype received from Pease. 

Whitish-corneous, solid shells, striped closely with brown 
or chestnut, chiefly on the last whorl (pi. 28, fig. 7) have been 
distributed by Garrett as striolata. They are probably closer 
to the following form and to nucleola. 


Another race, tangent from nucleola, is figured, pi. 27, fig. 
7. The dark brown shell is profusely striped on the last l 1 /^ 
whorls with cream-white. The columellar denticle is small 
and prominent. 

P. TVENIATA NUCLEOLA 'Pease' Garrett. PL 29, figs. 14, 15, 16. 

A small, compact, ovate-conic race. The surface is densely 
and distinctly striate spirally, but little shining, corneous- 
whitish, corneous-brown with wide indistinct darker and 
paler streaks, yellowish-brown or chestnut brown. The short 
spire is straightly conic; whorls about 4%, the last full be- 
low, rounded or somewhat flattened on the back. The colu- 
mella bears a small but rather acute tubercle in the middle, 
at the lower end of the axial expansion. There is no parietal 
tooth, but sometimes the very slight indication of one may 
be seen. 

Length 15, diam. 9, aperture 8.4 mm. 

Length 16, diam. 8.2, aperture 8 mm. 

Length 14, diam. 9, aperture 8 mm. 

This form is probably more primitive than the typical 
t&niata. It stands very close to P. filosa of Tahiti. The two 
are apparently of common origin. According to Garrett, 
nucleola intergrades with tceniata, yet it appears to be as 
distinct as elongata is. The largest examples measure 18 x 
10, apert. 9% mm- It lives in a small valley about two miles 
west of Opunohu.

Form corneola Hartman, pi. 41, figs. 15, 17. A form of 
nucleola has been described as a distinct species under the 
name P. corneola. It is similar to P. t. nucleola in most re- 
spects. The surface is dilute brown with some faint whitish- 
corneous streaks; surface very beautifully engraved spirally, 
the lines 'Close and somewhat waved. There are rather coarse 
longitudinal wrinkles on the back of the last whorl, readily 


appreciable in a 'basal view, as they cause the periphery to 
be irregular. The lip is like that of nucleola. There is a 
small nodule above the middle of the columella, and a small 
but well-developed callous nodule or tooth on the parietal 
wyll, deep within and near the columella.

Moorea (Mr. Greale). 

The larger of the two shells in Dr. Hartman's collection 
(no. 4242 Carnegie Museum) may be considered the type of 
this form or race, if it be found racially separable from 
nucleola. The chief difference is the possession of a parietal 
tooth by corneola, which is wanting or only weakly developed 
in nucleola. The back of the last whorl is also somewhat 
more roughened in corneola. The smaller of the two speci- 
mens mentioned in the original account of "corneola" is 
identical with nucleola. 

Pig. 15 represents the type; fig. 17 is a back view of an 
example in coll. Acad. Nat. Sciences, showing the wrinkles 
and the longitudinal streaking of the last whorl. 

I suspect that P. concinna Pse. was based on a specimen 
of nucleola.

longitudinally, narrowly umbilicate; whorls 5%, flatly eon- 
vex, suture somewhat impressed, very rarely marginated; 
aperture oblong oval, somewhat oblique, edentate, one-half 
the length of the shell ; lip evenly and somewhat roundly re- 
flected. Horn color or pale rose, striped longitudinally, or 
wholly straw color. Yar. encircled by three chestnut bands, 
more or less interrupted. " (Pease). 

"The headquarters of this arboreal species is in Vaianai 
valley on the southeast coast of Moorea, where it is abundant, 
associated with P. lineata (=suturalis) and P. mooreana. 
It occurs, also, but in less numbers, in a valley to the west- 


ward, where it is found in company with lineata and t&niata; 
The same valley, which is about two miles from Vaianai, is 
the limit of the range of the latter species on that part of the 
island, and hybrids between it and elongata are rather com- 
mon, the same as between garrettii and thalia at Raiatea. To 
the eastward of Vaianai it ranges throughout the small val- 
leys for a distance of several miles, as far as Oahumi, the 
specific centre of strigosa." (Garrett).

of which I would think it a subspecies, so far as I 
can judge without detailed study of the 'Colonies in the 
field. However, Garrett writes "I cannot agree with Dr. 
Hartman in uniting this species with taniata. It is only 
through hybrids between the two species that the inoscula- 
tion takes places. Examples taken in any of the valleys 
not inhabited by t&niata prove at once its distinction."

Length 17.2, diam. 8.8, aperture 9.2 mm., 4% whorls. 

Length 16, diam. 8.1, aperture 8.9 mm., 4% whorls. 

One shell is corneous-brown with inconspicuous narrow 
darker streaks, another is corneous-white with white streaks 
on the last whorl, while the third (fig. 6, and A. J. Conch, iii, 
pi. 1, f. 2) is dilute brown with indistinct, wide whitish 
corneous streaks. All have the dense, minute spiral sculpture 
of tceniata, and its allies. The whorls are not very convex, 
last one more or less flattened below the periphery, very con- 


vex at base. The lip is narrowly reflexed, a little thickened 
within. There is no noticeable callous nodule on the colu- 
mella, and no parietal tooth. 

Other lots show a wide range of variation in form and color, 
apparently showing considerable local differentiation. In one 
lot from Garrett (pi. 29, figs. 1, 2, 3, 4, 5) there are several 
color- forms: tawny shells with narrow browner streaks (fig. 
5) ; greenish white (fig. 1) ; pale brown or whitish with 4 in- 
terrupted bands (figs. 2-4). Another lot consists of yellow 
or yellowish-corneous shells, very indistinctly streaked (fig. 
11). Still other forms (figs. 9, 10) approach closely to typi- 
cal P. t&niata in color, having two widely separated whitish 
bands on a tawny-brown ground. 

21. P. ERHELII Morelet. PL 27, figs. 15, 16. 

Shell slightly umbilicate, acutely ovate, thin, diaphanous, 
decussate under the lens, covered with a grayish-tawny, in 
the last whorl yellow epidermis. Spire conic acute. Whorls 
5, a little convex, the last longer than the spire, angular in 
front. Aperture ample, very oblique, oval. Columella

Partula erhelii MORELET, Journ. de Conchyl. iv, 1853, p. 
371, pi. 12, f . 7, 8. PFR., Monogr. iv, 509 ; vi, 157. 

A thin little shell, writes M. Morelet, diaphanous, finely 
striate in both directions, recognizable by the obliquity of the 
aperture, the plane of which is inclined backward, as well as 
by the angular shape of the last whorl. The peristome is di- 
lated, reddish at the edge, thickened by a white callus which 
is sharply limited towards the inside. The slightly eurved 
columellar margin is applied over the umbilical region so as 
to almost wholly mask the opening. 

Dr. Hartman referred this form to P. taniata, but the 
features noticed in Morelet 's remarks, translated above, 
hardly warrant such a disposition of it. The lip-color and 


the angle on the front differentiate P. erhelii from otherwise 
similar known Moorean forms. M. Morelet states that it 
was brought from Tahiti by M. Erhel, a young surgeon of 
the marine service who died in Senegal. 

3. Species of Raiatea and Tahaa. 

The Partulse of these two islands are so intimately related 
that they must be treated together. The separation of the 
islands by a shallow lagoon about two miles wide, has evi- 
dently been a quite recent event. Both islands are enclosed 
in the same encircling reef. 

The extrinsic relations of the Partulae are with Tahitian 
forms. With the exceptions of P. turgida (no. 8) and P. 
attenuata (no. 17) already described, all Raiatean species 
may credibly be assumed to have descended from a single 
ancestral stock which was also the common parent of the 
otaheitana group. Subsequent events were as follows. (1) 
Three chief branches of this stock arose : the faba group, the 
dentifera group and the hebe group. (2) Each of these 
stocks spread over the available area, and (3) by local differ- 
entiation gave rise to numerous races, which are still doubt- 
less spreading and becoming further modified. This tertiary 
geographic radiation and racial differentiation was also ac- 
companied by an adaptive radiation whereby several arboreal 
forms gave rise to terrestrial species. As the result of these 
events we find most available stations occupied by two to four 
species, each representing one of the three stocks derived 
from differentiation (1), and from the adaptation to terres- 
trial conditions. 

The comparative simplicity of the distributional conditions 
indicates that the evolution cycle outlined above has not 
been of great duration. By analogy with known cases, dif- 
ferentiation (1) probably took place in Pliocene time. 

Most Partulag known to be terrestrial are from Raiatea and 
Tahaa. The terrestrial habit is no doubt a readaptation of 
arboreal ancestors. The coloration approximates to the dull 
tints of ground snails. 


Group of Partula dentifera. 

These arboreal snails of Raiatea and Tahaa are character- 
ized by the usually light yellow color of the shell, the sum- 
mit white, yellow, pink, or purple-tipped; lip white, thick- 
ened within, more or less strongly toothed within the outer 
lip and excised above the tooth. Columella and parietal 
wall often toothed. The species are closely related to some 
of the faba group. 

a. Shell denuded of cuticle, openly umbilicate; aperture 
rounded-oval, with two or three strong teeth. 

P. callifera, no. 22. 
aa. Cuticle present ; aperture ovate. 

6. Lip heavy, keeled on the face, with a heavy tooth 
above ; no columellar or parietal teeth. 

P. dentifera,, no. 24. 
66. Lip thinner, its face not keeled, 'tooth smaller. 

c. No parietal tooth, but having a columellar 

tooth; umbilicate, greenish-yellow, length 

23 mm. P. citrina, no. 25. 

cc. Parietal tooth usually developed; nearly or 

quite imperf orate; length 17 to 21 mm. 

P. imperf orata, no. 26. 

Properly speaking, this group consists of only three species : 
P. callifera of Haamoa valley, Raiatea ; P. solidula of unknown 
locality, and P. dentifera, of which formosa, citrina, imper- 
forata and virginea are scarcely more than subspecies, spread 
over Raiatea and part of Tahaa. P. imperf orata raiatensis 
and virginea are apparently the least modified survivors of 
the original stock. 

22. P. CALLIFERA Pfeiffer. PL 20, figs. 1, 2, 3. 

Shell umbilicate, ovate-conic, solid, nearly smooth (under 
the lens punctate-striate) , whitish. Spire a little convexly 
conic, rather obtuse. Suture light. Whorls 5, a little con- 
vex, the last a little longer than the spire, inflated. Columella 
subvertical, bearing a tubercle above, folded within. Aper- 
ture slightly oblique, sinuous-oblong, contracted by a deeply 


placed parietal tooth. Peristome thickened, dilated, the* 
margins joined by a callus, the right margin bearing 
an oblong callus within, above the middle. Length 19, 
diam. 11, aperture with peristome 11% mm. long, 4 wide in-

A beautiful and very distinct species, totally lacking cuticle 
in adult shells, and hence having a dull surface and cream- 
white color; the early whorls generally yellow, sometimes 
white. The last whorl is quite inflated, the aperture rounded- 
oval, usually three-toothed: there is a strong parietal tooth, 
a wider one above the middle of the outer lip, and a smaller 
denticle, or sometimes only an indistinct callous nodule, on 
the columella. The lip is generally thickened on the face, 
which is usually carinated. The size varies from length 17, 
diam. 11 mm., to length 21, diam. 12% mm. Fig. 3 repre- 
sents one of the specimens sent by Mr. Pease as megastoma. 

23. P. SOLIDULA Reeve. PI. 20, fig. 12. 

"Shell acuminately ovate, rather gibbous, compressly um- 
bilicated, solid, whorls flatly convex, obliquely irregularly 
striated, minutely sculptured with spiral impressed lines, 
aperture auriculate, the lip and columella being broadly cal- 
lously reflected ; straw-color, sometimes reddish at the apex. 

"A solid sub transparent shell, having the character and 
substance of P. otaheitana with the form and coloring of 
P. gibba; excepting that the whorls are not crowned with 


the white sutural band which is constant in that species."

This may 'be identical with one of the described forms of 
P. dentifera or imperforata, such as virginea, or more likely 
raiatensis ; but perhaps representing another race of the same 
stock, not rediscovered by Mr. Garrett. Pfeiffer's figures 
evidently do not apply to exactly the same form. Hartman 
expressed the idea that solidula is a large form of P. lutea. 
Garrett compares solidula to compact a Pse., from which it 
differs by the parietal tooth. Description and figure from 

24. P. DENTIFERA Pfeiflfer. PL 20, figs. 4, 9. 

The shell is narrowly umbilicate, ovate-conic, solid, nearly 
smooth, somewhat shining, pale straw colored. Spire conic, 
the apex rather acute, suture margined. Whorls 5%, the 
upper ones flat, the penultimate more convex, the last slightly 
shorter than the spire, convex, impressed in the middle an- 
teriorly. Columella subvertical, slightly folded. Aperture 
slightly oblique, narrow, obversely ear-shaped. Peristome 
white, strongly thickened, built forward; its margins sub- 
parallel, the right margin deeply curved above, and bearing 
a strong, acute, tooth-like tubercle in the middle. Length 
211/2, diam. 10, aperture 11 mm. (Pfr.). 

Raiatea: The specific centre of the type of this species is 
in the large valley of Vairahi, on the east coast of Raiatea, 
where it occurs in vast numbers on foliage in company with 
the typical P. hebe. It has not spread at all to the south- 
ward, but a variety occurs in an adjacent valley on the other 
side. ( Garrett) .

It may be distinguished by its elongate-conical form, straw- 
yellow color, rather shining surface, chink-like perforation, 
and small oblong obauriform white aperture. The peristome 
is ivory-white, heavily calloused, the face angularly ridged, 
strongly labiated within, and armed slightly above the middle 
with a very prominent tooth, above which the lip is strongly 
contracted, forming a conspicuous sinus. A very rare variety 
occurs of a ruddy 'brown color, purple-black apex, and flesh- 
colored peristome. Examples with a white sutural line are 
not infrequent and most shells are a little paler below the 
suture; otherwise it is never ornamented with bands; even 
the most perfect specimens always have the cuticle more or 
less decorticated behind the peristome, which suggested the 
provisional name decorticata. The above notes, slightly modi- 
fied from Garrett, apply to the typical P. dentifera from 
Vairahi valley, of which P. labiata Pease (fig. 9) is an exact 
synonym. In this form a parietal tooth is never developed. 
The color varies commonly from straw to light greenish yellow. 
The figured shell (fig. 9) measures, length 21, diam. 11, aper- 
ture 12 mm. but it is sometimes as small as 19 mm. long. 

Garrett states that north of Vairahi valley, P. dentifera 
"has migrated into a small adjacent valley, where it is much 
less abundant, and differs from the type in about half of the 
specimens having a prominent parietal tooth (which is al- 
ways absent in examples inhabiting Vairahi) ; otherwise the 
shells are not dissimilar. ' ' Examples of this dentate race are 
figured pi. 20, figs. 7, 8. It 'Certainly approaches close to 
P. imperforata raiatensis. 

P. dentifera is never banded, and the apex, though often 
yellow, is never rose-colored, as it often is in P. imperforata,. 


24a. P. D. FORMOSA 'Pease' G-arrett. PI. 20, figs. 5, 6. 

"Shell large, imperf orated, solid, elongate-ovate, striated, 
shining, pale yellowish white, straw-yellow or fulvous; spire 
conical, with nearly flat outlines, spirally striated with fine, 
crowded, incised lines, half the length of the shell, and fre- 
quently tinged with rose-red ; suture slightly impressed, mar- 
gined with a rugose, white line; whorls five and a half, flat- 
tened, the last one large, convex ; aperture oblong, subvertical, 
obaurif orm ; peristome white, rather widely expanded, decliv- 
ous, external margin angularly ridged, inner margin strongly 
labiated, acutely dentate, and contracted above the denticle ; 
parietal region thinly glazed, edentate ; columellar lip closely 
appressed over the umbilical region. Length 25, diam. 13 
mm. (Garrett). 

The metropolis of this very distinct species is in Patimu, 
or on the southwest part of Raiatea. It occurs 1 . in vast num- 
bers on 'bushes on the lowlands near the seashore, becoming 
more scarce inland, where it is found associated with P. 
hebe, var. bella. It ranges north as far as Vaiau valley, be- 
coming less and less abundant as the distance increases from 
its specific centre. (Garrett).

"Its large size, edentate parietal region, sharp labial tooth 
and closed umbilicus will readily distinguish it. It is never 
ornamented with bands/' The columella is slightly sinuous, 
but has no distinct tooth or nodule such as is present in 
P. imperforata. It differs from P. dentifera by its larger 
size and, imperforate axis and in its distribution. Fig. 5

lip. Aperture somewhat oblique, auriform, the lip well ex- 
panded, white, flattened or sloping inward, having a rather 
strong callous ledge within, which terminates upward in a 
wide tubercle, above which it is narrow and excavated. Colu- 
mella vertical, very little dilated at the insertion, where it 
is somewhat guttered,- an oblong callous nodule below the 
gutter. Parietal callus thin and transparent, not toothed.

Raiatea : ' ' restricted to a single valley called Uparu, on the

limited area in the upper portion of the valley. A few 
stragglers occurred lower down in company with faba and 
garrettii. ' ' ( Garrett ) .

This species stands very close to P. dentifera and P. im- 
perforata. It differs from dentifera by the flattened or in- 
wardly sloping lip, which is not keeled on the face, by the 
less prominent tubercle within the outer lip, and by the more 
emphatic nodule on the columella. Compared with P. im- 
perforata, it differs by the absence of a parietal tooth, the 
usually lighter color, larger size and slightly open umbilicus, 
all being inconstant characters. Garrett writes as follows: 
"Though considered by some authors to be a variety of P. 
faba, I am, nevertheless, fully 'Convinced of its specific value. 
When I first discovered it in 1861, I took but few examples, 
in consequence of not penetrating far enough into the valley 
to find its headquarters. A more extended research in 1873 


revealed its specific centre, and I took about eight 'hundred 
specimens in various stages of growth, and many of the adults 
were in a gravid condition. 

"It has been suggested that it may be a hybrid be- 
tween faba and some other species. I only noticed 
faba and garrettii in the lower part of the valley, and not in 
the upper portion, which is the principal haunt of citrina. 
Its uniform straw-yellow color, more slender form, smaller 
perforation, more reflected columella, and more decided labial 
tooth, and profounder emargination, will distinguish it from 
the very variable faba. 

1 ' My largest examples are 25 mill, in length and 12 in dia- 
meter. It is always of a straw-yellow color, rarely with faint 
longitudinal darker strigations, and is either lemon-yellow 
or light red at the apex. It is never spirally banded, and 
the parietal wall is invariably edentate. The oblong white 
aperture is, including the peristome, half the length of the 
shell. The ivory-white lip is broadly expanded, planulate, 
declivous, strongly labiated, slightly dentate and distinctly 
emarginate above. The slightly gibbous columella is re- 
flected over the small compressed perforation." 

26. P. IMPERFORATA 'Pease' Garrett. PI. 20, figs. 13, 14, 15. 

Shell imperforated or very narrowly compressly umbili- 
cated, solid, oblong- conic, somewhat shining, with rather 
smooth, irregular, incremental striae and closely set delicate 
spiral incised lines, which are more or less evanescent on the 
body-whorl. Color, pale straw-yellow, luteous, or fulvous, 
often with a brownish apex. Spire conical, with subplanulate 
outlines, about half the length of the shell ; suture sometimes 
margined by a rugose white line; whorls 5-5^2? flatly convex, 
the last one convex, or convexly rounded. Aperture sub- 
vertical, oblong, obauriform, white, sides nearly parallel; 
parietal wall with a more or less developed tubercular tooth; 
peristome white, thick, moderately expanded, its face con- 
cave, heavily labiated within, strongly contracted above, form- 
ing a rather profound sinus, and generally subdentate next 
to the emargination; columellar lip subnodose.

"Like all the species, they differ some in size, shape, and 
some have the spire more abbreviated than others. The type, 
which inhabits Hapai valley, is nearly always imperforated 
and may be distinguished from the imperforate formosa by 
its smaller size, gibbous columella and parietal tooth. Car- 
penter confused it with dentifera, an allied species confined 
to the opposite side of the island" (Garrett). 

Garrett 's description, slightly modified, is given above. 
His figured cotype and two others of the same lot are illus- 
trated, pi. 20, figs. 13-15. The length varies commonly from 
19 to 21 mm., diam. usually 11 mm. It differs from P. 
dentifera by the smaller tooth in the outer lip, by having a 
more or less distinct oblong callus lump oja the eolumella 
near its insertion, and a small parietal tooth (sometimes ab- 
sent) ; the face of the lip is less thickened than in dentifera. 
It is a less evolved race than dentifera. 

Typical imperforata is confined to Hapai valley. The 
valley Toloa is inhabited by a weakly individualized local race 
which has been called raiatensis Garrett (pi. 20, figs. 16, 17) 
and recta Pse. (in coll. 1863) not P. recta Pse. 1868. Gar- 
rett writes: "After a careful study of about 2000 specimens 
of the two species, I have annexed the Toloa with the Hapai 
shell. The only difference between the two is that raiatensis 
is usually lighter-colored, seldom imperforate, and the apex is 


much more frequently rose-red. It is, I think, more nearly 
related to the dentated virginea, inhabiting the neighboring 
island, than to dentifera." This conclusion is fully sup- 
ported by the series before me, received from Pease, Garrett 
and others.

Raiatea: The specific centre is in Vaipiti valley, on the 
west coast of Tahaa, where it occurs in the greatest pro- 
fusion on the foliage of shrubs. It has extended its range 
to the northward as far as Murifanna on the north coast, 
which latter is the limit of the western range of P. umbili- 
cata. ( Garrett) .

This form is practically identical with the raiatensis form 


of imperforata. Although I give Garrett's description above. 
I am convinced that no study of descriptions or of the type 
specimens, which I have before me, would enable one to 
separate a series of the two forms if mixed. The distinc- 
tion is based chiefly on geographic distribution but also 
to some extent on the diverse variations of the two forms. 
Pale specimens of virginea usually have the apex purple- 
tipped (not pink, as in raiatensis) ; but the darker shells have 
the embryonic whorls white. The only closely related or 
similar shell on Tahaa is P. planilabrum, which belongs to 
the fab a series.

to the northward, where it is found, though less abundant, in 
an adjacent valley, associated with the typical P. dentifera.

Typical P. hebe (pi. 21, fig. 1) has the shell covered with 
a very thin white more or less shining cuticle, upon which 
delicate spiral lines may be seen under the lens. Most ex- 
amples have lost their cuticle and have a matte white sur- 
face (figs. 2, 3). The size and proportions vary but little, 
the usual size being, length 15, diam. 10.2 to 11, length 
aperture 8.2 to 8.8 mm. 

The outer lip is rather narrow in the typical form ; in the 
heavy, denuded examples it is wide and heavily thickened 
within, generally showing a trace of the tooth or tubercle 
above the middle which is so prominent in the related faba 
group. It is often thickened on the face and convex or 
carinate there. The columella in oblique view in the aper- 
ture, is very wide. 

This charming snail has several close relatives among the 
dull ground-living species, such as P. crassilabris etc. 


P. HEBE BELLA 'Pse.' Hartman (pi. 21, figs. 4, 8) has the . 
spire orange rose colored, usually darker towards the apex. 
The surface is glossy, covered with a very thin yellow cuticle 
which is usually deciduous in part, or is entirely lost, 
when the whole surface is lusterless. The shell is often 
more solid than typical P. Jiebe. This form was named 
P. globosa, and P. h. bella by Pease many years ago, but it 
was in no manner described until Dr. Hartman reported on 
Pease's duplicates. 

I am unable to find much cause for recognizing var. 
ventricosa Garrett, 1884 (pi. 21, figs. 6, 7). It "is usually 
a little smaller than the type, not decorticated, and is more 
variable in color, but never banded. The ground color varies 
from whitish to fulvous, rarely with a reddish spire, but 
more frequently with the apex of a purple-brown. " (Gar- 
rett). The cuticle is decidedly thicker than in other forms 
of hebe; it peels off in an area behind the lip, but is else- 
where persistent. The parietal tooth is smaller than in other 
forms of hebe. Figured from examples received from Gar- 
rett. This form is probably what Dr. Hartman refers to as 
"P. ventrosa Pse." (t. c., p. 193). It approaches P. cras- 
silabris, a ground species, but differs by its much larger 
parietal tooth, etc. 

28. P. CRASSILABRIS Pease. PL 21, figs. 5, 9, 10. 

The shell is umbilicate, short, ovate-conic, moderately thick. 
Surface rather dull, lightly marked with growth-lines and 
usually showing engraved spiral lines distinctly on all the 
whorls; brown or corneous-brown, the base darker, spire or 
apex usually purplish-brown; periphery frequently (and 
typically) encircled with a yellow belt or line. The conic 
spire has straight sides ; whorls 4%, only slightly convex, the 
last rotund. The aperture is small, rounded-ovate, dark 
flesh-colored inside. Peristome expanded, thick in adult 
shells, thickened within, its face convex, white, or brownish 
towards the outer edge. Outer lip is a little narrower above, 
but not dentate; at the insertion it gives off a short parietal 


callus. The columellar margin has no 'callous tubercle or 
node, 'but in oblique view is seen to be very broad. It is 
angularly bent at the insertion. Parietal wall covered with 
a thin, transparent callus, bearing a small white tooth far 

Length 14.5, diam. 10 mm. 

Length 15.3, diam. 9.3 mm. 

Length 15 to 16, diam. 10 mm. 

Raiatea : The metropolis of this species is in Hapai valley, 
on the west coast of Raiatea, the home of P. imperforata 
and lugubris. It is very abundant, lurking beneath decay- 
ing vegetation and 'found associated with the typical form 
of P. lugubris. It has not spread any to the northward, but 
to the southward it has migrated into two small ravines.

This small ground-snail is very closely related to P. hebe. 
It differs from that by the dull brown color, smaller parietal 
tooth (which indeed is sometimes wanting), the less ex- 
panded lip, and persistent cuticle. The description and 
fig. 10 are from Pease's type lot, no. 59477 A. N. S. P. The 
color is variable. 

a. Yellowish chestnut, the base darker, summit purplish, a 
pale brown peripheral line (fig. 5). 

b. Chestnut, the spire darker, purplish ; often a white hair- 
line at suture (fig. 9). 

c. Light brown or brownish-corneous, summit darker, peri- 
phery indistinctly marked with a light or a dark band. 

d. Greenish-corneous, lip pure white. An albino. 


29. P. RUSTICA Pease. PL 19, figs. 12, 15 to 18. 

The shell is rather openly umbilicate, obesely ovate-conic, 
somewhat thin. Surface rather dull, lightly marked with 
growth-lines and spiral engraved lines, which are generally 
subobsolete on the last whorl except near suture and base; 
chestnut-brown, sometimes having a pale belt, or pale brown- 
ish-corneous, the summit or spire purplish-brown. Spire 
conic with straight outlines; whorLs 4%, slightly convex, the 
last rotund. The umbilicus has a more or less distinct spiral 
groove or excavation within. Aperture subvertical, ovate, 
dark flesh-colored within; peristome narrowly expanded, 
thickened within, noticeably narrower near the upper inser- 
tion. Columellar margin sinuated or weakly nodose with- 
in; in oblique view less 1 wide than P. crassilabris. Parietal 
wall covered with a transparent callus which is rather thick 
at the edge, and often bears a very small tooth far within. 

Length 16.7 to 17.7, diam. 11 mm. 

Length 16, diam. 10 mm. 

Raiatea: The metropolis of this species is in a large 
valley called Toloa, on the west coast of Raiatea, where it 
occurs in great abundance beneath decaying vegetation. It 
has migrated to the southward into two small adjacent val- 
leys, but does not extend its range so far as Hapai, the next 
large valley, and the home of the allied P. crassilabris.

Partula pinguis GARRETT, 1. c. p. 77. 

Described from Pease's type lot, no. 59480 A. N. S. P. 
Garrett writes as follows: ''It is larger, less globose, the 
aperture more oblong, than P. crassilabris with which it has 
been confounded. Its chief character consists in the colu- 


mellar region 'being, as it were, pressed in towards the aper- 
ture, nodulous on the inner margin, and subangulated at the 
base. The parietal tooth is less developed and absent more 
frequently than in crassilabris. The coloration is the same 
in the two species. Like the majority of the ground species, 
it varies in -a greater or less degree in shape and size. Some 
forms almost exactly simulate P. garrettii, not only in the out- 
line of the shell, but in the peculiar shape of the aperture as. 
modified by the columella being pressed inwardly. Occa- 
sionally examples occur which are so much abbreviated that 
they resemble P. crassilabris, but may readily be separated by 
the dissimilarity in the columellar region. 

"My P. pinguis, of which I have seen only a dozen ex- 
amples, was found under decaying leaves in the mountain 
ravines, at the head of Vaioara valley. It certainly equals 
rustica." (Garrett). 

30. P. GARRETTI Pease. PI. 21, figs. 15 to 19. 

The shell is minutely rimate or imperforate, oblong-ovate, 
solid and strong, slightly shining, lightly marked with 
growth-striae and minute engraved spiral lines, which are 
usually more or less obsolete on the last whorl; yellowish, 
the spire either paler, apex white, or spire pink-tinted with 
the apex purplish, flesh colored. Suture very lightly impressed, 
edged with a white line. Whorls 5, very slightly convex. 
Aperture is oblique, white within. Peristome very narrowly 
expanded, thick, the face convex or keeled, pure white; in- 
ternal rib strong. Columella vertical, sinuous, bearing a 
strong tubercle or node above the middle, its junction with 
the basal margin angulated. Parietal wall covered with a 
smooth, transparent callus, not toothed within. 

Length 16, diam. 9 mm. 

Length 14, diam. 9 mm.

Baiatea : ' ' The specific centre is Vaioara, on the west coast 
of Raiatea, where it exists in prodigious numbers on bushes. 
It has spread north and south of its metropolis, and in the 


former direction has slightly overlapped the southern range of 
P. thalia, and hybrids between the two species are quite com- 
mon. To the southward it ranges about one mile, where it 
extends a short distance up a valley which is the home of 
P. citrina." (Garrett) .

Differs from the related P. thalia and P. rustica by its 
less inflated form, extremely narrow or closed umbilicus, less 
expanded lip and strongly developed columellar sinuosity. 
Garrett remarks that "Its principal characters are its small 
size, contracted aperture, rounded or angulated peristome 
and nodulous columella, which latter is, as it were, pushed in 
towards the aperture. The parietal region is very rarely 
toothed. It is whitish or pale yellowish horn-color, rarely 
fulvous or light brown, and sometimes the apex is purple- 
brown. A variety with a brown base and sutural band is not 
infrequent. ' ' 

Fig. 15 represents one of Pease's original lot. Fig. 19 
is somewhat intermediate between garretti and rustica. It 
has the columella and almost closed umbilicus of garretti, but 
a somewhat fuller shape and a minute parietal tooth. 

31. P. UMBILICATA Pease. PI. 21, figs. 11, 12, 13, 14. 

The shell is globosely ovate, solid, rather dull openly nm- 
bilicate, roundly angulate at the umbilicus, very delicately 
striated spirally. Whorls 4%, convex, the last swollen. 
Aperture rounded-oval, toothed. Lip internally thickened, 
obliquely flat. The columella has a somewhat tooth-like cal- 
lus, and is angular at the base. Color, yellowish or brown- 
ish horn-color, faintly streaked with darker, the apex gener- 
ally reddish-brown or dark purple ; seldom wholly dark chest- 


nut-brown; occasionally with a broad yellowish, horn-color 
band ; very rarely yellowish horn-color with a chestnut band. 

Length 18, diam. 12.5 mm. (Pease). 

Tahaa: The metropolis of this well-defined species is in a 
large valley called Haamene, on the east coast of Tahaa, where 
they are found in prodigious numbers on the foliage of low 
bushes. It has not spread any to the southward, but, on the 
other hand, ranges in considerable numbers through all the 
valleys, except Faa-apa, the home of bilineata, as far as 
Murifanna on the northwest coast, where it is found asso- 
ciated with P. virginea. (Garrett).

P. umbilicata unites characters of the auriculata and the 
rustica groups in some degree, though nearer rustica, of which 
it might be called a very large and obese edition. The outer 
lip is a little narrower in its upper fourth than in P. thalia, 
and there is a distinct callus, often dentiform, superposed 
upon the columella. The parietal tooth varies from small to 
well developed, and seems to be invariably present. There 
is often an indistinct appearance of several angles in the out- 
line of the outer lip, which is moderately expanded, and 
cream-white behind, white on the face. The whole surface 
generally shows spiral striae. Umbilicus much wider than 
in P. thalia. The last whorl is typically well inflated, but 
I have seen specimens with a strong peripheral angle, from 
retention of a juvenile character in the adult stage. 

Color various; the commonest pattern before me is chest- 
nut, fading to yellowish-white below the last suture, gradu- 
ally shading to purplish-black at the apex ; but sometimes the 
whole shell is straw-'eolor. In fig. 11 it shows one of the 
common color-patterns of the faba group. Figs. 13, 14 rep-

32. P. THALIA Garrett. PI. 19, figs. 10-11, 13. 

"Shell compressly perforated, solid, ovate-conic, somewhat 
shining, lines of growth rather smooth, and revolving incised 
lines very fine and crowded ; whitish or yellowish horn-color, 
with or without a purple-black apex ; spire rather short, coni- 
cal, with plano-convex outlines, half the length of the shell; 
suture slightly impressed; whorls five, flatly convex, the last 
one large, subglobose. Aperture subvertieal, shortly subauri- 
form; parietal region more or less glazed, and armed with 
a white tubercular tooth; peristome white, moderately ex- 
panded, thick, angularly ridged, strongly incrassated within, 
sinuous above, and the margins frequently joined by a ridge 
of callus. The columella is frequently slightly gibbous or 
nodulous in the inner margin. Length 17, diam. 11 mm. 

"Var. a. Fulvous brown, with or without purple-black 
apex. Rather rare. 

"Var. b. With brown base and sutural band. Not com- 
mon." (Garrett). 

Raiatea: "The specific centre of this very abundant arbo- 
real species is in Huaru valley, on the west coast of Raiatea. 
It has spread along the well-wooded lowlands about two miles 
north and one mile south of its metropolis, slightly over- 
lapping the northern range of P. garrettii." (Garrett).

"It is smaller, smoother, more shining, much less variable 
in color, and the aperture is less auriform than P. auricu- 
lata." The smaller P. garretti is probably its nearest ally, 
but that is a narrower species with more oblique aperture,. 


more strongly tuberculate columella, and usually no parietal 
tooth. P. thalia seems to 'be a quite distinct species. I have 
seen a large number besides Garrett 's type lot (figs. 10, 11), 
mostly labeled "P. abbreviata Pse.," a preoccupied name.

northward, but occurs in limited numbers in all the valleys 
south as far as Vairahi, the headquarters of P. dentifera."

A dull, streaked species, with "key-hole" aperture, the 
outer lip having a prominent tooth projecting inward, above 
which it is very narrow. The parietal tubercle is variable, 
but usually present. Apex may be either white or blackish- 
brown. Length 20 to 22, diam. 11. Length 21, diam 11.5 
mm. It was first described by Garrett, in 1884, although 
Hart-man had given a brief descriptive note in 1882 (Bull. 
M. C. Z., ix, 185, 196). It was widely distributed by Pease, 
and in consequence of an ill-judged identification by Cuming 
and Carpenter, has generally been known in collections as 
"P. compressa Pfr." Garrett 's type, no. 59409 A. N. S. P. 
is figured, fig. 5. Others from Pease (fig. 6), Hartman and 
others are before me. P. radiata stands very close to P. 
fusca approximata of the southern part of Raiatea, but it is 
duller, with a larger lip-tooth and generally it has a parietal 
tooth. In the several forms of P. fusca, the parietal tooth, 
when present, is not so large as in radiata. 

A form which Pease called P. microstoma (in his collection, 
1863), and which inhabits Vairahi valley, "though very fre- 
quently found adhering to the lower portion of the trunks of 
trees and shrubs, can scarcely be separated from radiata, 
which is strictly terrestrial in habit. Dr. Hartman unites it 
with P. vittata. It appears to me more nearly related to 
radiata than the latter, which is smoother, and the 'Columellar 
lip is flat and simple." (Garrett). 

Fig. 14, of pi. 27 represents a specimen of microstoma 


received from Hartman. It measures, length 23.7, diam. 13^ 
aperture 12.2 mm., has the shape of radiata, but the tooth 
within the outer lip is less developed. There is no parietal 
tooth. The 'base of the last whorl and a band below the 
suture, ascending the spire are chestnut, leaving a rather wide 
pale buff zone. The surface is not quite so dull as in 
radiata. Whether this form is identical with Garrett 's 
Vairahi microstoma remains uncertain. The discussion be- 
tween Hartman and Garrett about the identity of Pease's 
microstoma is academic, since Pease never described the form. 
It was first described (by accident, and quite unrecognizably) 
from Hartman 's collection, by H. H. Smith, as cited .above. 

According to Garrett, specimens which he regards as hybrids 
between P. radiata and P. fab a are of common occurrence.

or less distinctly decussated by the spiral lines. Spire 
straightly conic. Whorls slightly more than 5, moderately 
convex. Aperture ovate, the lip only slightly or narrowly 
expanded, a little thickened within, usually flesh-colored, 
thinner near the upper insertion. Columella dilated above, 
not calloused or nodulous. Parietal wall covered with a very 
thin transparent glaze, toothless. Coloration various:

This is a very thin member of the faba group, deficient in 
lip callus and teeth, smaller and more lightly built than 
P. fusca, which is also a ground snail. 

The race described by Pease as P. ovalis (pi. 19, fig. 7) 
differs from lugubris only by being a little larger, more solid, 
with a stronger lip-callus. It replaces lugubris in Vaiau 
valley, the typical lugubris being confined to Hapai valley. 
It approaches very near to P. vittata, which is a larger form 
with longer spire and a small parietal tooth. The ovalis form 
is usually dark chestnut with a yellowish belt, but sometimes 
is of a uniform chestnut hue. 

Mr. Garrett writes: "My largest Vaiau specimens are 20% 
mm. long, -and 11 mm. in diameter. The smallest adult from 
Hapai is 16 by 8 mm. I have found hybrids between lugubris 
and imperforata, the latter a strictly arboreal species. 

"Dr. Hartman, overlooking the fact that lugubris, ovalis, 
protea and fusca inhabit widely separated valleys, has sug- 
gested that the three former may be the juvenile and adoles- 
cent forms of the adult fusca. The habitats of the two former 
species are about two miles apart, and five miles south of the 
location of fusca. P. protea, which = fusca, is confined to 
the opposite side of the island, and is separated from the lat- 
ter by an almost inaccessible mountain. ' '

P. faba was first obtained when Captain Cook visited 
Raiatea in 1769. Andrew Gurrett writes as follows : 

' * The type varies from straw-yellow to brownish yellow or 
fulvous, with a broad basal and narrow sutural chestnut- 
brown band. The most common bandless variety is of the 
normal color varied with longitudinal darker strigations. A 
variety of a uniform, whitish horn-color, as well as one of a 
uniform chestnut-brown, sometimes approaching black, is not 
infrequent. The lip is white, and the apex frequently tinted 
with purple-black. 

They vary considerably in shape, as the following measure- 
ments will prove : 

Length 25, diam. 14 mill. 

Length 25, diam. 12 mill. 

The average dimension is 25 by 13 mill. Out of about 
6000 examples I found but one possessing the parietal tooth. 
Hybrids between this species and radiata, fusca and naviga- 
toria are not uncommon." 

Fig. 1 is a copy ol Martyn's type figure. Fig. 2 is a more 
streaked example of the typical form. Deep brown (fig. 3), 
and greenish-yellow (fig. 4), examples are also drawn. Figs. 
5 to 8 are from a series collected by C. D. Voy, presumably in 
one colony, the several color-forms being connected by inter- 
mediate stages. 

P. subangulata, amanda, navigatoria and fusca might be 
ranked as subspecies of faba without going far wrong. 

36. P. SUBANGULATA Pease. PI. 16, figs. 14, 15, 16. 

Shell smoother, more glossy and thinner than P. fal>a\ 
chestnut-colored with darker streaks and a yellow band below 
the suture ; early whorls purplish-black or brown- tinted ; the 
peristome dark flesh colored, often with white spots. Varies 
commonly to chestnut with streaks but no light band, and to 
light yellow or olive-yellow with chestnut streaks and white 


spire. A variety with a narrow subsutural and subbasal band 
of a dark chestnut color on a pale greenish yellow ground is 
not uncommon. 

Tahaa, at the southern end in several valleys ( Garrett) .

The pale subsutural band gives the shoulder an appearance 
of angulation, which does not really exist. While the Tahaan 
forms of the faba type differ but little from Raiatean faba, 
yet their variation- forms are somewhat diverse, and the minor 
differences noted above seem fairly 'constant. I have therefore 
thought it best, in view of the minute specific subdivision of 
Raiatean Partulae, to give subangulata specific rank. 

36a. P. s. AMANDA Garrett. PI. 17, figs. 1, 2, 3. 

The shell is like subangulata in shape, but it occasionally 
has a small tooth on the parietal wall. The usual color is 
pale yellow or greenish yellow, almost white towards the 
summit, or more or less suffused with fulvous, with a white 
or flesh-tinted lip. "A beautiful variety occurs which has a 
wide median reddish chestnut band (fig. 1). A more common 
variety is found with two narrow reddish chestnut bands" 
(fig. 2) ; the summit in these is purple-black. "'Chestnut- 
brown varieties are not uncommon. The rarest variety is 
fasciated the same as the typical faba." (Garrett}. 

Tahaa, occurring in greatest profusion in the northeastern 
part, but spread all over the island except in the area of 
subangulata (Garrett). 


A subvariety of amanda has been called var. dubia Garrett- 
(pi. 17, figs. 4, 8) but that name was already in use for a 
Tahitian form of the otaheitana group. It is yellow with a 
white spire, white lip, and invariably has a parietal tooth. 
Some specimens have a chestnut umbilical area, or are some- 
what suffused and streaked with fulvous, and the apex is 
pinkish brown. This form is found in some valleys on the 
north coast. 

37. P. NAVIGATORIA (Pfeiffer). PI. 16, figs. 9 to 13. 

Shell perforate, dextral, oblong-ovate, solid, obsoletely 
granulose-striate, rather shining; fulvous, marked with close 
darker lines. Spire conic, rather acute, suture light, white- 
edged. Whorls 5, nearly flat, the last longer than the spire. 
Aperture oblong, narrow, whitish within, provided with a 
small callous [parietal] tooth deep on the ventral side of the 
penult whorl. Peristome somewhat thickened, strongly 
white-lipped within, the margins parallel, right margin nar- 
rowly expanded, somewhat toothed in the middle, columellar 
margin dilated, flat, reflexed. Length 23, diam. 11, aperture 
13 x 8 mm. Type in Mus. Cuming. (Pfr.) . 

Lower portion of Vaioara valley, on the west coast of 
Raiatea and spread along the lowland forests south as far as 
Uparu valley; very abundant, associated with P. fusca; usu- 
ally lurking beneath decaying vegetation, but sometimes taken 
on the trunks of trees. (Garrett).

This form differs from P. faba chiefly by having the last 
two whorls less convex than usual in that species, and the 
aperture is narrower, more contracted. Moreover it lives. for 
the most part on the ground, and has its own patterns of 
coloring, which however do not differ much from the patterns 


of faba and fusca. G-arrett writes that "hybrids between this 
species and fusca and faba are very frequent." 

The typical coloration of navigatoria (fig. 9, copied from 
Reeve) and the synonymous variabilis is yellow, profusely 
streaked with chestnut, the spire often pinkish. This is the 
normal or usual form. Other patterns are: 

Uniform yellow. Not common. 

Uniform dark chestnut, or with pale apex. Not 'common. 

The last form, greenish yellow, the base and a subsutural 
band chestnut, is not uncommon; it resembles typical P. 
faba in pattern. 

' * The parietal tooth mentioned by Pf eiffer, but not alluded 
to by Reeve or Pease, is not constant, but exists in about two- 
fifths of the adults. The former author's 'medio subden- 
tato,' likewise not mentioned by the latter two writers, is 
simply the lower angle of the small labial sinus. 

"In shape it varies from ovate to oblong-ovate, as the fol- 
lowing two measurements will show: Length 25, diam. 
13 mm.; length 20, diam. 13 mm." (Garrett). 

38. P. FUSCA Pease. PI. 17, figs. 5, 6, 7. 

' * Shell umbilicated, solid, varying from an abbreviate-ovate 
to oblong-ovate, roughly striated by irregular lines of growth, 
and the usual fine spiral incised lines become evanescent on 
the body-whorl; spire convexly conical, less than half the 
length of the shell ; suture linearly impressed, frequently mar- 
gined by a thread-like white line; whorls 5-6, more or less 
flatly convex, last one large, convex, rounded or turgid, some- 
times slightly angled just above the aperture; base more 
openly umbilicated than usual in the ground species; aper- 
ture subvertical, oblong, sides nearly parallel ; parietal region 
more or less glazed with callus, and sometimes dentate ; peris- 
tome rather broadly expanded, moderately thick, slanting, 
flat or concave, strongly incrassated within and sinuous 
above ; columellar lip depressed, receding or transversely 
grooved above. Color very variable : whitish corneous, straw- 
yellow, fulvous, light or dark chestnut, sometimes brown- 


black, and frequently strigated. Yellowish horn-colored ex- 
amples with the base and the sutural band chestnut, are not 
uncommon. The lip, though usually white, is frequently mar- 
gined with purple-brown. Length 20, diam. 11 mm. 

"The above is about the average dimensions. My largest 
example is 24 by I3y 2 and the smallest adult 17 by 10 mm. 
Sometimes, though rarely, the spire equals half the length of 
the shell. Very old examples have a more or less nodulous 
columella and a more or less distinct denticle on the outer 
lip." (Garrett).

Raiatea: The metropolis of this very variable ground 
species is in Vaioara valley, on the west coast of Raiatea, the 
headquarters of P. garrettii and navigatoria. It has not 
migrated any to the southward, but to the northward it oc- 
curs sparingly far up in Huaru valley. On the opposite side 
of the island it is found in Tepua valley, and I took a few 
in a small ravine more to the southward. The Tepua shell, 
which is the protea Pse., differs none from his fusca. 

' ' Hybrids between protea and the arboreal P. faba are not 
uncommon, and are usually found adhering to the lower 
parts of the trunks of trees. 

"In Vaioara, hybrids between fusca and navigatoria, and 
between the two former and faba, are so frequent as to be 
very embarrassing in the separation of the three species col- 
lected in that valley. Like the Tepua hybrids, all those be- 
tween the two ground species and the arboreal faba live on 
the lower parts of the trunks of trees." (Garrett). 


Illustrated from specimens received from Garrett. Others 
from Pease are before me. This snail lives under cover on the 
ground, and the shell is less glossy than navigatoria or faba 
which differ from fusca and vittata chiefly by their arboreal 
habits and brighter shells. The lip is usually expanded more 
than in vittata, which replaces fusca on the southwest. P. 
fusca occasionally has a small parietal tooth, but in vittata 
the tooth is almost invariable in fully adult shells. 

38a. P. F. VITTATA Pease. PI. 17, fig. 16. 

The shape of the typical vittata is oblong-conic, more or 
less compressedly umbilicated, and the spire, which equals 
half the length of the shell, has straight outlines. The last 
whorl is not angular in front of the aperture. The ample, 
oblong aperture is 'considerably contracted by the intrusion 
of white callus on the inner margin of the peristome, and the 
sides are nearly parallel. The peristome is rather thin, 
widely expanded and usually stained with brownish purple. 
The white callus does not extend to the upper end of the 
lip, leaving a shallow sinus. The columella is flattened, not 
calloused or nodose, and reflected over the umbilicus. The 
color is whitish, yellowish corneous, fulvous or horn-color, fre- 
quently with the basal third of the body and a sutural band 
chestnut-color. Sometimes the apex is black or purple-black. 
The parietal tooth, though small, is constant, but so far 
within that it is hardly visible in a front view. 

Length 23, diam. 13 mm. (fig. 16). 

Length 24, diam. 12 mm. (Pease). 

Length 25, diam. 11 mm. (Garrett, maximum size). 

Society Islands : Restricted to the higher portions of Toloa 
valley, on the west coast of Raiatea, not uncommon under 
decaying vegetation. (Garrett).

Doubtfully distinguishable from P. fusca. The figure is 
drawn from the shell already figured by Garrett, who col- 
lected the type lot. He states that " no examples were dis- 
covered in Hapai or Vaiau, the headquarters of lugubris and 
ovalis, which two valleys are between Toloa and the small 
ones inhabited by approximate."

This is a race subsidiary to vittata characterized by its 
inferior size, smaller umbilicus, which is frequently imper- 
vious, smaller aperture, and less expanded lip. The parietal 
tooth is very seldom developed. The banding is similar in 
the two forms, but occurs rarely in approximata, which dif- 
fers also in being generally a lighter or darker chestnut-color, 
though both have similar horn-colored varieties, with brown 
streaks. The last whorl is usually angular in front, as in 
var. terrestris. 

Occurs in greater or less profusion in several small valleys 
on the southwest part of Raiatea. 

Cotypes from Garrett are figured. 

38c. P. F. TERRESTRIS 'Pse.' Garrett. PI. 17, figs. 9, 10, 11. 

The shell is moderately umbilicate, thin, with only a trace 
of spiral striae on 'the last whorl. It is (1) corneous with 
.yellowish streaks, (2) chestnut 'Colored, or (3) chestnut with 
an equatorial yellow zone. The apex is usually pale, but 
sometimes purple. The last whorl is rather acutely angular 
immediately in front of the upper termination of the outer 
lip ; or if not, an angle may be traced above the suture, near 
the aperture; the immature stage being strongly angular. 
The aperture is rather narrow, with a distinct prominence at 
the upper end of the lip-callus. Lip moderately expanded, 


white or pale. Columella concave, with no callus or nodule, 
A very small parietal tooth is usually present.

Differs from P. vittata chiefly by the distinct angulation of 
the body in front of the aperture. Gotypes in coll. A. N. S. 
P., no. 59450. Garrett writes: 

"In the valleys on the southern part of the island 
(Raiatea), we find a gradual change from the typical P. ap- 
proximata into the form known as P. terrestris Pease, which 
latter connects the former with vittata. The range of ter- 
restris terminates at Opoa valley, on the southeast coast. 

"At Faaloa, on the east coast, there exists a form, P. cas- 
tanea Pease, which is intermediate between terrestris and 
vittata. It is usually chestnut-colored, constantly toothed on 
the parietal wall, and the fasciation is the same as in the other 
varieties. It has not spread any to the northward of Faaloa, 
but occurs more sparingly in a small valley between Faaloa 
and Opoa." (Garrett). A specimen of castanea received 
from Pease is figured (pi. 17, fig. 12) . It is absolutely iden- 
tical with terrestris.

The callous rim and * * tooth ' ' within the outer lip are more 
strongly developed than in P. faba, fusca and their immedi- 
ate allies. There is an Oblong callous lump on the face of 
the columella, more or less visible in different examples. The 
white border below the suture is an important feature of the 
species, very rarely wanting. P. planilabrum is larger and 
more elongated than P. bilineata, and the surface is not so 
smooth and shining. The structure of the peristome is similar 
in the two shells, but the aperture is more elongate in 
planilabrum. The parietal tooth is constant in adults but 
varies in size. The following color-forms are found. 

PI. 18, figs. 2, 3. The type is deep chestnut-brown, gradu- 
ally fading into yellowish corneous towards the sutural line; 
the whitish lip is frequently tinged with violet.

tinct oblique streaks. Rare. 

Numerous specimens from Pease and Grarrett show it to 
be rather constant in form, but some shells show an angle on 
the last whorl, in front of the aperture. Grarrett writes: 
44 The metropolis of this species is Haamene valley, on the 
east coast of Tahaa, where it is common, and, though usually 
lurking beneath decaying vegetation, is sometimes found ad- 
hering to the trunks of the wild banana. It is found, though 
less abundant, in a valley north of its specific centre, but does 
not occur in the intermediate valley Faa-apa, the home of 
bilineata. ' J 

40. P. BILINEATA Pease. PL 19, figs. 8, 14. 

The shell is rather openly umbilicate, ovate-conic, solid, 
smooth and glossy, marked lightly with growth-lines. Spire 
almost straightly conic, the apex frequently dark. The suture 
is margined with a white line. Ground-color whitish-corneous, 


pale yellow or brownish yellow, typically with a narrow 
brown band revolving a short distance below the suture, and 
a wider one just below the perifery; but sometimes the 
whole base is dark chestnut, or the whole shell may be dark 
except for a light equatorial girdle or zone. The aperture is 
nearly white inside, lip broad, white, well expanded and 
strongly thickened within. The columellar lip bears on its 
inner face a low nodule, sometimes hardly noticeable. The 
parietal tooth is deeply placed and well developed.

P. plamlabrum is more lengthened and less glossy than 
bilineata, and the two have not the same cycles of color-forms. 
P. umbilicata is a still more shortened and globose form. 
These three species of Tahaa are slight modifications of the 
ancestral Raiatean P. auriculata stock. Fig. 14 represents 
Pease's type specimen. Garrett writes of P. bilineata: "It 
is readily distinguished by its smooth, glossy surface, ovate- 
conic form, yellowish horn-color, and two revolving chestnut- 
brown bands, the upper one narrow and subsutural. The 
subacute apex is sometimes purple-brown and the suture is 
margined by a narrow, rugose, whitish line. The constant 
parietal tooth is prominent and the broad white peristome 
is slightly emarginate above, strongly labiate within, and 
widely expanded.

This arboreal species is obese, solid, not very glossy, with 
a moderate or quite narrow umbilicus. The lip is not very 
broadly expanded, but is strongly thickened within, white, 
flat, often more or less dentate, and is conspicuously excised 
above. The columella is oblique, broad, and bears a moder- 
ate or heavy callus which is notched at the insertion above. 
The parietal tooth is well developed. 

Length 20, diam. 13.5 mm. 

Length 21, diam. 13.3 mm. 

P. auriculata has been united by many authors with the 
totally different P. otakeitana of Tahiti. The erroneous 
locality "Huaheine" was given by Cuming, who collected 
the types. As Pease and Garrett have already remarked, 
P. auriculata was evidently based upon several forms of this 
group, but the emphasis laid by Broderip upon the flat lip 
indicates that the form described as P. compacta by Pease is 
practically typical auriculata. Reeve's Conchologia Iconica, 
Partula plate 2, figure 11& may be considered the type of 
P. auriculata. I have figured similar shells, pi. 18, figs. 10, 
11. The color is usually light brownish yellow, but it varies 
to light chestnut in the lots before me. Fig. 9, copied from 
Reeve's figure of one of the original lot, is unlike the com- 
pacta I have seen in being banded. Pease's type of com- 
pacta, now before me, is a typical auriculata in develop- 
ment of the apertural callosities. In many individuals the 
"teeth" are less developed, as in fig. 8. 

410. P. A. ROBUSTA Pease. PI. 18, figs. 13 to 16. 

The shell is somewhat smaller than the largest P. auriculata, 


more compactly ovate, very solid, the lip very little ex- 
panded and very much thickened on the convex face, though 
less broad than in auriculata, and with less prominent in- 
ternal callosities, hence the aperture is more open. The 
parietal tooth is smaller than in auriculata, and often almost 
disappears. The lip is generally brown-edged, and often a 
raised callus connects the ends. The columellar lip is seen, 
in profile view, to be very thick, and the umbilical crevice 
is narrow. Color-patterns as follows: 

a. Last li/2 or 2 whorls corneous, copiously streaked ob- 
liquely with chestnut; the next earlier whorl rich chest- 
nut, deepening to purple-black towards and at the sum- 
mit. This is the typical coloration. 

6. Yellowish, with some faint brownish streaks, apex pale. 
Approaches auriculata in form. 

c. Dark chestnut throughout, with more or less distinct 
paler oblique streaks on the last whorl. 

d. Chestnut colored with a broad corneous or yellowish 
zone above the middle of the last whorl. This pattern 
also occurs in auriculata. 

Length 19.5, diam. 11.5, aperture 11 mm. (fig. 14). 

Length 17.5, diam. 11, aperture 10 mm. 

P. robusta has not before been figured, but descriptive 
notes were published by Smith in his catalogue of the Hart- 
man collection. Types no. 59444 A. N. S. P. 

4. Species of Huaheine. 

Huaheine possesses four species all endemic. Two (P. 
arguta and annectens) are restricted to two valleys, and the 
latter, like P. clara, appears to be gradually becoming extinct. 
Both species are remarkably uniform in all their specific 
characters, and are related to forms of Tahiti and Baiatea. 
On the contrary, the other two species (P. rosea and varia) 
have spread nearly all over the island, and are subject to 
considerable variation. Neither is closely related to other 
Society Island species, but a form scarcely distinguishable 
from varia occurs at Rarotonga. It is worthy of remark that 


dentated species, which are so common in all the islands ex- 
cept Bora/bora, do not occur on Huaheine. 

The structure of the kidney raises a doubt as to the sys- 
tematic position of P. rosea and varia. They may belong in 
or near the section Samoana rather than to Partula s. str. 

42. P. VARIA Broderip. PL 23, figs. 1 to 12. 

Shell openly perforate, ovate-pyramidal, thin, glossy, com- 
posed of nearly 5 convex whorls, the last rounded perif erally, 
or slightly subangular in front ; very convex or saccate at the 
base. Surface with sculpture of fine growth-striae and min- 
ute spiral lines, which are more or less obsolete on the last 
whorl. Aperture vertical, white or purplish-brown within, 
the lip reflexed, evenly thickened within, white or purple- 
brown. Length 17, diam. 11 mm. 

Huaheine: "The metropolis of the typical P. varia is in 
two valleys on the west coast of Huaheine, where they are 
very abundant on foliage, but it is generally distributed 
throughout all parts of the island." (Garrett) .

This common Huaheine species is smaller and more glossy 
than P. rosea, and differs in its range of color- variation. Ac- 
cording to Andrew Garrett, the type form "is very variable 
in coloration, and considerably so in size and shape. The 
smallest form, which = P. pulchra, Pse., gradually merges 
into the type, and is restricted to the larger of the two valleys 
called Hamene. The type which equals my huaheinensis and 
adusta, is usually corneous, luteous, more frequently fulvous, 
rarely white, and the most abundant variety is dark chestnut, 
sometimes nearly black with a pale apex and dark or pale lip 
(fig. 1). Deep chestnut- colored examples, with a wide or 
narrow central pale band, are not uncommon (fig. 2). The 
form with an obscure central fulvous band on a pale ground, 
is rather common (figs. 6, 7). 

"In the higher portion of Hamene may be found a large 
form (Mcolor Garr., not of Pease) which is either uniform 
straw-yellow, or greenish yellow, with or without a dark chest- 
nut spire. It differs from the typical varia in being larger, 
more robust, the whorls more inflated and the aperture wider. 
Specimens from Garrett are figured, pi. 23, figs. 4 and 8. 

"In a valley named Faahiti, on the northern part of the 
island, we find in the greatest profusion, associated with 
P. rosea cognata Pse., a form shaped like 'bicolor,' but 
smaller and more variable in color than the typical varia. 
The most common variety is light yellowish, sometimes stri- 
gated, the lip, and sometimes the base, stained with burnt- 
brown or violet-brown. Nearly half of the specimens are 1 
uniform fulvous brown, or chestnut-brown approaching black. 
The variety with central pale band is also very frequent, as 
well as the one of a uniform whitish or luteous with white lip. 
The pale variety with chestnut spire is somewhat rare, besides 
one with a dark spire and two narrow bands on the body- 
whorl. A lot of these shells sent to the 'Museum Godeffroy/ 
were by Prof. Mousson referred to Morelet's P. simplaria, 
and have been freely distributed under that name. Morelet 
cites 'Tahiti' as the habitat of his species. His 'apice obtuso 
rosaceo' and 'sutura albo marginata' do not occur in these 


shells, nor any of the varieties of varia" hence the name 
simplaria should not be applied to them. Specimens of 
various color-patterns are figured, pi. 23, figs. 9, 10. 

The form called P. glutinosa Pf r. is straw colored or pale 
fulvous, the lip white with a purplish-brown border. It was 
originally described as from the Solomon Islands. Fig. 11 
is a copy of the original figure. A specimen received from 
Cuming is drawn in fig. 15. "P. perplexa Pse. MS." of H. 
H. Smith is the same. 

P. mucida Pfr. was based on the uniform chestnut colored 
form of varia. A figure of the type specimen in the British 
Museum is given, pi. 41, fig. 13. 

43. P. ROSEA Broderip. Plate 22. 

The shell is openly perforate, rather thin, ovate-pyramidal, 
moderately glossy ; Tinder a lens it is seen to be marked with 
fine growth-lines and close, waved, distinctly engraved spiral 
lines. Whorls 5, very slightly convex, the last generally 
angular at the periphery, in front of the aperture. The aper- 
ture is ovate, slightly oblique ; outer lip well expanded, thin- 
edged, strengthened with a narrow callous rim within, gradu- 
ally tapering to the upper end. Columella thin, dilated above. 
Parietal film transparent, toothless. 

Length 22, diam. 13 mm. 

Length 23, diam. 13 to 15 mm. 

The typical color (pi. 22, figs. 1, 2) is uniform rose, in- 
cluding the interior and lip ; but in many examples the em- 
bryonic whorls are paler or yellowish with a pink sutural line. 

Huaheine: "The headquarters of this beautiful and well- 
known arboreal species is in a large forest at the head of 
Hawai bay on the west side of Huaheine. From this region, 
where they are very numerous, they have spread over many 
parts of the island. They differ but little in shape in the 
different localities, except in Faahiti on the north coast, where 
they (the P. cognata Pease) are smaller, less angulated on 
the last whorl, and in the total absence of the uniform dark 
purple-brown and rose-colored varieties which are so com- 


mon elsewhere. The most numerous variety of the cognata 
form is straw-yellow with the sutural line tinted with rose or 
purple rose. A rose or purple-'brown variety with a centra] 
yellow band is found in no other part of the island/'

Besides the common typical rose-colored form (figs. 1, 2), 
the following color-patterns occur. From Garrett 's remarks 
it appears that several of the patterns occur together, so that 
they seem ordinarily to have no racial status. The some- 
what smaller form cognata seems to have incipient racial

lip violet, <common (fig. 3). 

3, form bipartita. Upper surface rose (fig. 4) or purple 
(fig. 5) base pale yellow, the lip white. " Frequent in the 
metropolis of the species but very rare elsewhere ' ' ( Garrett) . 

4, form bicolorata. Spire rose or purple, fading at the 
end of penultimate whorl to straw yellow or corneous on the 
last whorl; apex whitish; mouth and lip white (figs. 6, 7). 

5, form straminea. Straw-yellow or yellowish-'corneous, 
the apex or whole spire corneous- white ; aperture and lip 


white (figs. 8, 9). According to Garrett this form is very 

6, form zonata. Yellow, with the base and a narrow or 
rather wide sutural 'band brown, purple-brown or rose-color, 
mouth bicolored. Common (fig. 10, 11). Varies in size 
from 24 x 13.5 to 21.5 x 12.5 mm. 

7, form cognata 'Pse.' Garrett. Often smaller, length 
9.5 to 23 mm., yellow with the suture tinted with rose or 
purplish; aperture white (pi. 22, figs. 12, 17; pi. 33, fig. 3), 
"Very common in Faahiti valley, but rare elsewhere" (Gar- 
rett). This small form varies to light yellow with pallid 
spire, and to yellow with purple or roseate spire, like form 
bicolorata ; or it may have the color of form no. 6. 

8, form estaUiaiia, 'Garrett' Smith. Shell small, thin, 
whitish-corneous or yellowish, with the base and a band be- 
low the suture rose or dull purple, leaving the lighter tint in 
a broad zone or band. Occurs in Faahiti valley only (figs. 
13, 14). 

This form varies to yellow or corneous-yellow shells, with 
the spire corneous or more or less purple-tinted, lip whitish 
or with a purplish tint (figs. 15, 16). 

Broderip's original description of P. rosed follows: 
"Shell ovate-pyramidal, roseate; whorls 6, longitudinally 
substriate, subdecussate with very close lines, the last larg- 
est; epidermis thin.. Length %, diam. % inch. 

"Var. a, purple-brown. Var. &, whitish, sutures and base 
of the last whorl roseate, epidermis yellow." (Brod.). 

44. P. ANNECTENS (Pease). PL 24, figs. 5, 6. 

The shell is perforate, oblong-ovate, very thin, pellucid, 
slightly yellowish corneous, sometimes with a pale ruddy tint 
at the apex, the suture bordered with an opaque white line. 
Surface lustrous, showing fine growth-lines, and very close, 
minutely crimped, spiral striae throughout. Whorls 4^, con- 
vex, the last one compressed or somewhat flattened below 
the periphery, therefore unusually convex close to the perfora- 
tion. The aperture is quite oblique, ovate ; peristome thin, re- 


flexed throughout, white, the columellar margin dilated and 
bifurcate above. Parietal wall covered with a scarcely 
noticeable film. 

Length 13, diam. 7.25 mm. ; aperture 7.8 mm. 

Length 14, diam. 7 mm. ; aperture 7.8 mm. 

Huaheine: "This delicate arboreal species is excessively 
rare, and has only occurred to my notice in two valleys on 
the west coast of Huaheine. ' ' ( Garrett) .

"It is more fragile and less slender than P. attenuata, the 
nearest allied form. The spire is less than half the length 
of the shell, and the suture is margined by a white line. The 
dull whitish peristome is widely expanded. The aperture is 
never dentate, and the yellow- corneous shell is faintly tinged 
with greenish. 

"The animal varies from pale luteous-yellow to light 
brownish yellow. The soft parts, as seen through the trans- 
parent shell, are mottled with slate-colored spots. The foot 
is about the same length as the shell, and the ocular peduncles 
are very long and slender." (Garrett). 

5. Species of Borabora. 
45. P. LUTEA Lesson. PI. 23, figs. 16, 17, 18, 19. 

This species resembles the preceding [P. lineata], but it 
is distinguished by having the peristome less thick, by the 
umbilicus, of which the crevice is obliterated. Its altitude 
is 8 lines by 5 in diameter. Its spire is more swollen than 
in the preceding. The shell is thinner, and entirely corneous 
yellow. The Yellow Partula lives on the island of Borabora 

Society Is.: Borabora (Lesson, Garrett, Voy) ; widely dif- 
fused throughout the island, on the trunks and foliage of 
trees and bushes. (Garrett).

PFEIFFER, Proc. Zool. Soc., 1856, p. 334. 

This is a rather solid, obesely ovate-conic shell, with 
straightly conic, acute spire and rather glossy surface. The 
spiral striation is generally weak in the median part of the 
last whorl, more distinct above and below. The first two 
whorls are flattened and slope steeply, giving the apex a more 
acutely conic shape than usual. Whorls 5, the post-embryonic 
ones rather convex, last whorl inflated. The aperture is 
somewhat oblique; outer lip reflexed and thickened within, 
white. Columellar margin only very little dilated at its in- 
sertion, near which it is thickened by a callous deposit on 
the inner margin of its face. The parietal wall is covered 
with a transparent callus, which near the lip-ends is thick- 
ened and white. There is no parietal tooth. The umbilicus 
is reduced to a very narrow, short chink. The color is 
variable : 

1. Uniform pale yellow. 

2. Pale yellow with brownish apex. 

3. Isabelline, the first 2% whorls purple-brown or blackish 

4. Purple-brown, covered on the last whorl with a yellow 
cuticle, which is thin and transparent on the spire, the 
suture white (lilacina Pfr.). 

The size and snape vary. Lesson 's type was evidently near 
the small extreme in size. Shells from a lot collected by 
C. D. Voy, color-forms 2, 3, 4, measured: 

Length 19, diam. 11, aperture 10.1 mm. 


Length 18.8, diam. 11, aperture 10.5 mm. 

Length 18, diam. 11.5, aperture, 10.8 mm. 

Others are more ventricose : 

Length 19.8, diam. 12.2, aperture 11.5 mm. 

Length 17.2, diam. 11, aperture 10 mm. 

Length 17.4, diam. 11, aperture 9% mm. 

According to Garrett, "notwithstanding its wide range 
over the island, it has not developed a single local variety. 
In fact it exhibits less variation than some of the species at 
the other islands which are restricted to single valleys. " 

Dr. Hartman and Andrew Garrett are agreed that Partula 
lilacina Pfr. is a color-phase of P. lutea. A figure of the 
type specimen in the British Museum is given, pi. 41, fig. 14. 

6. Species of unknown habitats, probably from the Society Is. 

The following will probably prove to be forms of some of 
the species already known from the Society Islands; but 
their status can only be determined by examination of the 
type specimens. 

46. P. STOLIDA Pease. 

"Shell elongate, ovate, dextral, rather dull, umbilicate, 
very finely roughened longitudinally and indistinctly under 
the lens striated transversely; whorls 5, convex; suture im- 
pressed; aperture elongately oval, rather small, not one- 
half the length of the shell, dentate, rarely edentate; lip 
somewhat roundly thickened, chestnut or olivaceous, ob- 
scurely and very finely striped longitudinally. Length 20, 
diam. 10% mm. Tahitian archipelago. Terrestrial. " 
(Pease) . 

Partula stolida PEASE, Amer. Jour. Conch., 1866, p. 198; 
Proc. Zool. Soc., 1871, p. 473. PFEIFFER, Mon. Hel. Viv. 
viii, p. 195. 

Garrett, in his work of 1884, identified specimens of P. 
compressa as stolida ; but they cannot be made to agree with 
Pease's description. Pease himself, in 1871, gives the locality 
Raiatea; yet his testimony is of doubtful value. Perhaps 


P. stolida will prove, if the type specimen can toe found, to 
be a form of the otaheitana series from Tahiti. 

47. P. NITENS Pfeiffer. 

Shell subperf orate, conic-ovate, swollen, rather thin; longi- 
tudinally very delicately striate; glossy, diaphanous; tawny- 
brown, above obsoletely, at the base broadly banded with 
buff. Spire conic, rather acute. Suture lightly impressed, 
whitish. Whorls 5, a trifle convex, the last about equal to the 
spire, rounded at the base. Aperture slightly oblique, acu- 
minate-oval; peristome white, the right margin somewhat 
spreading above, moderately expanded; 'Columellar margin 
dilated, spreading somewhat over the perforation. Length 
17, diam. 10 mm. ; aperture with peristome 10 mm. long, 4% 
wide inside. (Pfr.).

der a lens very minutely striated spirally, slightly shining, 
straw colored radiated with white and tawny lines. Spire 
conic, the apex acute; suture deep, submarginate.' Whorls 
5%, convex, the last a little shorter than the spire, somewhat 
tapering basally. Columella receding above, vaulted over 
the umbilicus. Aperture slightly oblique, truncate-oblong; 
peristome white, spreading and reflexed. Length 22, diam. 
10 mm.; aperture 9 x 41/2 mm. inside (Pfr.).

Shell perforate, ovate-conic, rather ventricose, yellowish- 
fulvous, thin, striolate, and delicately decussate towards the 


apex; spire conic, the apex obtuse, roseate. Whorls 
little convex, the last slightly more than half the total length ; 
suture white-margined. Aperture subvertical, ovate, the 
throat whitish; peristome thin, narrowly expanded, pale 
Hesh colored, the columellar margin dilated, overhanging.

This Partula is distinguished from P. varia by its swollen 
shape, obtuse summit, wider, less oblique and more rounded

tome (Morelet). 

This form has not been rediscovered, and its locality is 
uncertain. It stands near P. assimilis', and by some authors 
has been considered a form of P. rosea or P. varia.

The figure does not agree well with Pease's measurements. 

"We have no locality for the above species. It appears to 
approach the Marquesan type, and may be allied to lilacina 
Pfr. It is covered with a thin epidermis, which, when worn 
off, would probably leave the shell without color, as is the 
case with ganymedes, Pfr. We have but a single specimen. ' * 


The few species of these groups are very closely related to 
those of the Society Islands, and no doubt are of common 

In the Austral Group, Partula hyalina (see p. 180) is 
found on Tubuai and Rurutu (Oheteroa). No other Partula 
is known from the group. One island, Rurutu, has been 
somewhat carefully explored for land shells (see Garrett, 
Proc. A. N. S. Phila. 1879, pp. 17-30). 

In the Hervey or Cook's Group, P. hyalina has been found 
on Mangaia and Rarotonga. P. assimilis Pse., a form very 
close to P. varia of Huaheine, occurs on Rarotonga. Pease- 


has stated that the Raiatean P. ~kebe is found on Mangaia 
(Journ. de Conchyl. 1870, p. 401) 'but his records occasion- 
ally prove erroneous, and this one seems doubtful. 

52. P. ASSIMILIS Pease. PI. 41, figs. 5, 9. 

The shell is narrowly umbilicate, ovate-conic, rather thin; 
corneous or faintly yellowish-corneous, nearly uniform, but 
under a lens it appears to be very indistinctly marked with 
pale brown streaks; the early whorls are sometimes pale 
brown. 2y s embryonic whorls with the usual subpunctate 
spiral lines, succeeding whorls finely weakly striate spirally, 
convex. The last whorl is quite convex, very indistinctly 
marked with more or less effaced spiral lines, or they may 
be almost wholly absent. Aperture slightly oblique, white 
or flesh-tinted within. Peristome white or flesh-colored, re- 
flexed and somewhat thickened within. Columellar lip di-

This species closely resembles the pale, yellowish form of 
P. varia of Huaheine, but differs by the thinner, less conic 
shell, with the spire more swollen, apex more obtuse and 
the lip is less thickened within. 

Pease has described a "var. virgulata, shell generally 
shorter than the typical form, longitudinally streaked with 
light red; alt. 15, diam 9 mm. Rarotonga." 

Two specimens out of the Pease duplicates, from a series 
received from Dr. Hartman, have the summit purplish, like 
the form of P. varia figured on pi. 23, fig. 4, yet I do not 
feel certain that they are really from Rarotonga. 



The Samoan Partulae are still very imperfectly known, 
species having been collected only on Upolu and Tutuila. 
Nothing is known of the species of the largest island, Savii, 
if any exist there, or of several smaller islands of the group. 

The known forms belong to four groups, quite diverse in 
texture and coloration, but two of them are alike in having 
the umbilicus unusually open.

This species differs from P. conica by its longer, more slen- 
der spire, absence of spiral striae except on the embryonic 
whorls and base, the darker tint, etc. It is said to be in- 
variably sinistral, and restricted to the island Upolu. 

The color is greenish-yellow with more or less chestnut suf- 
fusion, sometimes darker in narrow streaks. The spire is 
darker, reddish brown; suture margined with a white line, 
narrower than in P. conica. The peristome is flesh-tinted, 
not so broad as that of P. conica, and the columella is gut- 
tered at its junction with the body. The umbilicus is ample, 
as in P. conica. Figs. 6 and 7 were drawn from one of the 
original lot collected by Schmeltz. Specimens measure as 

Length 28, diam. 17, aperture 16 mm. ; 5% whorls. 

Length 27, diam. 16.5, aperture 16.3 mm. ; 5y 2 whorls. 

Length 28.3, diam. 16.8, aperture 15 mm. ; 5% whorls. 

Length 25.8, diam. 15.8, aperture 14.7 mm. ; 5% whorls. 

A single specimen before me (pi. 32, fig. 8) has a much 
shorter spire than canalis, not attenuated as that is. The 
color is dark chestnut, the spire dull dark purple. It is 
spirally striate below the periphery. Length 23, diam. 15, 
aperture 13.3 mm. ; whorls slightly over 5. Upolu. This may 
represent a distinct subspecies.

Some specimens collected by the United States Exploring 
Expedition differ from canalis by having the last whorl more 
swollen above the periphery, tapering to the base, and there- 
fore distinctly conic; the umbilicus is much narrower, and 
the plane of the peristome is more oblique.

whorls and a subsutural margin being white. The surface 
is glossy. Whorls 5%, the first half -whorl smooth, follow- 
ing 2% whorls spirally engraved (fig. 8) ; on the following 
whorls the spire striae are almost wanting, but they reappear 
on the last whorl, which is very closely sculptured through- 
out with fine wavy spirals, stronger towards the base. The 
whorls are moderately convex, the last whorl rather swollen 
peripherally and very convex at the base. The aperture is 
ovate, rather oblique; peristome white, flatly, rather widely 
reflexed, dilated at the columellar insertion and somewhat 
excavated or grooved at its junction: with the base. Parietal 
callus very thin, transparent.

In his descriptions of this species, Gould considered the 
large, more or less chestnut colored and smoother form later 
described as P. canalis to be -a form of conica, and he also, 
by implication, included the dextral form, his words "in- 
terdum sinistrorsa" indicating that he 'had seen dextral ex- 
amples. It is obvious that Gould considered the sinistral 
form to be typical from his selection of sinistral examples 
for figuring, and from his comparison "resembling Bulimus 
l&vus in form"; yet his description is composite, the num- 
ber of whorls referring especially to the larger brown form 
(canalis) and the description of sculpture to the striate form 
here considered to be the true conica. Garrett's restriction 
of P. conica to the dextral form was not allowable under the 
existing conditions. 


One of Gould's figures is copied, fig. 1. Other figures 
drawn from the same type specimen are given (figs. 2, 3, no. 
2687 A. N. S. P.). The whitish spiral lines on this shell are 
apparently pathologic. 

This species is distinguished from P. canalis by the white 
spire of fewer whorls (5% to 5%), the more developed stria- 
tion of the last whorl and the comparatively larger aperture. 
In some examples, such as that shown in fig. 5, the spiral 
striation of the last whorl is hardly visible above the middle. 

Gould's second locality for this species, "Raraka," is a 
low island (atoll) of the Paumotu group, where it is prac- 
tically certain that no Partula lives.

described form, about which very little is known. Garrett 
placed upolensis in the synonymy of P. conica, but he seems 
to have had P. stevensoniana. A specimen purchased from 
the Godeffroys as P. upolensis (no. 59845 A. N. S. P.) as from

This form seems to be known by the original lot only. It 
stands close to P. canalis and P. conica, having spiral sculp- 
ture like the latter, and coloration more like canalis. The 
cuticle is readily deciduous on the summit and in a band 
along the suture. The compact, subglobose shape distin- 
guishes it from allied species. It is shorter and wider than 
P. stevensoniana, 'and the aperture is larger.

This species is related to P. expansa, but differs 'by its 
narrower, less deeply penetrating umbilicus, longer spire, and 
especially by the spiral striation of the last whorl, which 
was described by Gould (see fig. 11, drawn from below the 
suture just back of the outer lip). 

The opaque buff markings appear mostly as oblique streaks 
along the lines of growth, but they often tend to become trans- 
formed into spirally descending stripes, especially on the 
last half whorl, approaching the condition of the further 
evolved P. expansa. Often the cream tint predominates over 
the corneous or brown markings, which remain as streaks 
or spots. 


Partula tryoni Hartman (pi. 31, fig. 5) is a zebrina in 
which the cream-white markings are reduced to mere flecks. 
While this color-pattern may possibly be characteristic of a 
local race, it is surely nothing but a form of P. zebrina. I 
have figured the type specimen (no. 4261 Carnegie Mus.). 
It was erroneously supposed to be from the Solomon Islands. 

Partula actor Albers differs in no respect from zebrina.

This form differs from P. zebrina by its larger last whorl 
and shorter spire. Whether it is a true race or merely a 
phase of individual variation I have not the means of deciding.

In fig. 16 the white spots and stripes follow the direction of 
growth-lines, and stand on a corneous-brown ground. In fig. 
13 the flecks and spots are mainly lengthened in a spiral di- 
rection, but arranged in oblique series ; the ground being very 
dark brown. The whole shell is marked with spiral lines, as 
in P. zebrina.

The shell is broadly and deeply umbilicate, obliquely ovate,

or spots, which descend spirally and obliquely forward. Spire 


very short, conic ; whorls 4 or slightly more, convex, the first 
2~y 2 composing the embryonic shell are uniform gray, the first 
half whorl smooth, the rest very closely marked with en- 
graved spiral lines, which rapidly disappear on the next 
whorl. About the middle of the penultimate whorl some 
white spots appear in the gray surface, the first ones being 
arranged along growth-lines; they rapidly change to spirally 
lengthened spots and belts which may be either continuous or 
interrupted on the last whorl. The last whorl is lightly 
marked with growth-lines but has no spiral strice. It is in- 
flated and very convex at the base. Aperture lateral, dia-

the last whorl, etc. The locality Tutuila, originally given by 
Pease on Brazier's authority, is apparently erroneous. It 
has been taken by Garrett and Schmeltz on Upolu. Pease's 
type specimen (drawn in my figure 14) is not fully mature, 
the expansion and thickening of the lip being incomplete. 
The pattern of opaque white stripes is interrupted, leaving 
snowy dots and streaks over part of the surface. 

Group of P. brazieri. 

The following species seems to be very intimately related 
to the group of P. caledonica, and belongs to the section 
Melanesica forms inhabiting the New Hebrides and neigh- 
boring groups. It has the same pyramidal shape, indistinct 


strigation and subperipheral band, etc. We have no sufficient 
ground for doubting the evidence of an experienced collector 
that P. brazieri inhabits the Samoan Islands; yet up to this 
time no other naturalist has encountered it there. 

59. P. BRAZIERI Pease. PL 33, figs. 1, 2. 

The shell is dextral oblong-acuminate, openly and deeply 
rimate, rather thin, glossy, whitish, having a very thin cuticle 
which on the last whorl is indistinctly streaked with very pale 
greenish-yellow, this color strongest in an indistinct belt 
below the periphery, and on the base. After the first half 
whorl the embryonic shell (fig. 2) is sculptured with close, 
punctate spiral striae ; post-embryonic whorls sculptured with 
engraved spiral lines, which are rather widely spaced, and 
on the last half of the last whorl are obsolete above periphery. 
Spire conic, rather slender above. Embryonic shell of 2% 
flat whorls; following whorls convex, the last whorl convex 
above, very full basally. Aperture slightly oblique, white 
within. Peristome narrowly reflexed, thickened within, 
white, tapering towards the upper termination, where it is 
continued in a small triangular callus filling the angle of 
the aperture. Columellar lip dilated inwards, a trifle grooved 
along its junction with the body ; its outer edge continued a 
short distance upward on the parietal wall. Parietal callus 
transparent. Length 24, diam. 13.1, length of aperture 12.9 
mm. ; whorls 5%. 

Samoan Islands: Tutuila (Brazier). 

Partula ~brazieri PSE., Amer. Journ. of Conch, vii, 1872, 
p. 27, pi. 9, f. 5. Cf. GARRETT, Proc. A. N. S. Phila. 1887, 
p. 135, and HARTMAN, Nautilus xi, 44. 

Described and figured from the unique type, no. 59846 A. 
N. S. P. Garrett and Hartman have expressed doubts as to 
the locality assigned by Pease on the authority of Brazier. 
The shell is so similar to species of the New Hebrides that it 
seems possible that it was obtained in that group. Trading 
schooners from Sydney usually touched at numerous islands, 
exchanging their cargoes of rum, cloth, guns and trinkets for 


copra, and the shells "brought from various places might 
easily become mixed. 

Group of P. gonochila. 

The relations of P. gonochila and P. subgonochila to- 
other Partulae are uncertain. 

60. P. GONOCHILA (Pfeiffer). PL 41, figs. 6, 7, 8, 10. 

Shell subperforate, ovate-conic, thin, delicately and closely 
decussate, diaphanous, green. Spire conic, rather acute; 
\\horls 5, slightly convex, the last convex, longer than the 
spire. Columella obsoletely plicate above. Aperture oblong, 
obliquely truncate above; peristome broadly, angularly ex- 
panded, a little reflexed, thin, white inside, the margins re- 
mote. Length 17, diam. 9, aperture with peristome 10 x 7

Pfeiffer 's description and figures (pi. 41, figs. 7, 8) are 
copied. The specimen drawn in figs. 6, 10, is slightly less 
swollen than Pfeiffer 's, measuring, length 18, diam. 10.3, 
aperture 10 x 7 mm., whorls 5. The last whorl is whitish 
under a very thin pale greenish yellow cuticle. The 
spire is red-brown, darkest at the apex; on the penul- 
timate whorl it becomes paler in the middle, a darker shade 
continuing as a border above and below the suture as far as 
the lip. The growth-striae are fine and distinct. Engraved 
spiral lines are fine and close, strongest on the last whorL 
The whorls including the last are evenly convex; base con- 
vex, shortly rimate and deeply perforate. The lip is re- 
flexed, opaque white behind the reflection. It is strengthened 
by a very strong, narrow white callous rib within. This rib 
diminishes gradually above, and extends upward on the coin- 


mellar margin two-thirds of the distance to the insertion, 
terminating rather abruptly near the lower end of the oblique, 
straight columellar fold. 

The habitat of this species is not known, even the group 
assigned (Sainoan) being uncertain. 


Tonga Is. species. 
61. P. SUBGONOCHILA Mousson. PL 41, figs. 11, 12. 

Shell perforate, ovate-conic, finely, widely decussate, stria- 
tulate, greenish. Spire convexly-conic, regular, the summit 
rather obtuse ; suture not impressed, submarginate. Whorls 
4%, slightly convex, the last moderately convex, not as long 
as the spire, not ascending in front. Aperture rather small, 
sub vertical (making an angle of 5 degrees with the axis), 
oblong, obliquely truncate above. Peristome expanded, 'angu- 
larly reflexed, whitish, somewhat labiate within, the margins 
not approaching ; right margin curved in a long arch above ; 
columellar margin vertical, wide, spreading, not folded with- 
in. Length 16, diam. 9.6 mm. (Mouss.) . 

Tonga Is. : Futuna or Fotuna, in the Home group, and 
Vavau (Dr. Ed. Graeffe). 

Partula subgonochila Mouss., Journ. de Conchyl. xix, 1871, 
p. 14, pi. 3, f. 4. 

This species resembles P. varia to some extent, but the spire 
is less produced. Two lots from the Bartman collection are 
before me: No. 4284 Carnegie Mus. is from "Fortuna, 
Friendly Is.," coll. by Brazier (apparently Futuna, the type 
locality). The shell is thin, pale greenish yellow on the last 
whorl or two, fading to whitish above near the suture, the 
spire whitish. The spiral strias are rather close and very dis- 
tinct, and on the last whorl the peripheral 'angle is so in- 
distinctly indicated, that the contour remains rounded. The 
summit is quite obtuse. The lip is white. The largest of 
four measures, length 17, diam. 10, aperture 9 mm., whorls 
4%. The smallest is 16 mm. long. 


No. 4285 Carnegie Mus., four specimens labelled "Tu- 
tuila." Smaller than the preceding, the spiral striation not 
so strong on the last whorl, lip flesh-tinted. Length 14%, 
diam. 9, aperture S 1 /^ mm., whorls 4% 

P. gonochila Pfr. is no doubt closely related to subgono- 
ckila. In both the spiral striation of the embryonic whorls 
is very fine 'and distinct, and the pitting is conspicuous. 
P. gonochila is a more solid shell, darker colored, with the 
lip more thickened within, and the upper part of the spire 
more narrowly conic. 

Rotuma species. 
62. P. LEEFEI (E. A. Smith). 

' 'Shell dextral, small, ovate, umbilicate, yellow-olivaeous, 
pale below the suture and towards the apex; spire moder- 
ately produced, rounded at the apex. Whorls 5, a little con- 
vex, closely sculptured with delicate growth lines and very 
fine spiral striae, more or less obsolete on the last whorl ; last 
whorl hardly descending in front. Aperture ovate, brown- 
ish inside, about half the total length; peristome white, ex- 
panded and reflexed, slightly thickened. Length 14, diam. 
9 mm. ; aperture 6 x 3~y 2 mm. inside" (Smith) .

"A small species, distinguished by its style of coloration 
and general form." 

Rotuma lies between the Fiji and Ellice Is., about 300 miles 
N. N.-W. of the former. Its size is about 8x2 miles, with 
a height of 800 ft. 

Fiji species: Section THAKOMBAUA, n. sect. 

The single Fijian Partula, P. lirata, is very distinct by the 
coarse spiral sculpture of the post-embryonic whorls and the 
tubercular callus or tooth on the parietal wall near the 

P. lirata has no near relatives among known forms, and for 


it the section Thakombaua is here instituted. It is somewhat 
remarkable that in Fiji no Partulas are known from the 
islands inhabited by Placostylus. The same is true of the 
New Caledonian group; but in the New Hebrides and 
Solomon Islands both genera exist. 

63. P. LIBATA Mousson. PL 34, figs. 15, 16, 17, 18. 

The shell is long ovate-conic, rather thin, rimate; white, 
pale yellowish, pale brown or rather dark liver brown with 
narrow paler streaks. Surface lusterless. The embryonic 
shell consists of nearly 3 whorls, the initial half whorl smooth, 
following half whorl very subtly punctate-striate spirally, 
spirals on the next whorl fewer, rather separated, and mainly 
on the upper part ; third whorl with very weak spirals, which 
at the beginning of the post-embryonic shell become distinct 
but low cords. These increase in prominence to the last 
whorl, where there are 8-12 strong spiral cords above the 
periphery, with small, unequal cords in most of the intervals, 
and on the base are many smaller unequal cords and threads. 
These spiral cords extend to the lip-edge, which is crenulated 
in all but old specimens. The last whorl is somewhat com- 
pressed laterally -and convex at the base. Aperture ovate, 
oblique, colored within like the outside. Peristome narrowly 
expanded, thickened within ; columella dilated above. Parietal 
wall covered with a distinct but transparent callus, which 
bears a white callous tubercle far within near the root of the 

Length 18.2, diam. 9.8, aperture 9.5 mm. ; whorls 5%.

The single Fijian Partula has 'been found only on the small 
islands of the "eastern group," the genus being unknown on 
the large islands, where Placostylus 'abounds. The rarity of 
Partula in this archipelago is at present inexplicable. The 
single species is one of the most distinct of the genus. 

Mr. Layard stated in a letter to Dr. Hartman that he did 
not find the species on Taviuni or Lomma-lomma, in six 
weeks collecting on the former and a day or two at the latter

Sterope HARTMAN, Catal. genus Partula, 1881, p. 14, type 
P. carteriensis Q. et G. ; not of Groodsir 1845, or Hagen, 1850. 

Partulae of simple form and coloring, corneous, yellow or 
brown, uniform or obliquely streaked, not banded; aperture 
not obstructed by teeth; the peristome either thin or thick- 
ened within. Suture often bordered above by a thread, which 
continues indistinctly on the last whorl as a low welt or 
group of closer striae. Type P. turneri. 

This group includes all of the species of the New Hebrides, 
Solomon Is., New Ireland, New Britain, New Guinea, and 
other adjacent islands, as well as one Samoan form, 
P. brazieri. 


The Santa Cruz group, Banks and Torres Islands and New 
Hebrides form a group trending from N. W. to S. E. through 
about 10 degrees of latitude. The southern islands, Ero- 
manga, Aneiteum, are not remote from the Loyalty Islands 
which lie on a parallel fold, and have no Partulae. The 
northern or Santa Cruz end of the group approaches the 
Solomon Islands. The fauna is only imperfectly known, but 
seems to be somewhat related to that of the Solomon Islands, 
though much poorer and more primitive by lacking Papuina, 
Chloritis, etc. M'any of the islands are high and wooded. 

Group of P. turneri.

swollen, saccate base. 

64. P. TURNERI Pfeiffer. PI. 33, figs. 5, 6. , 

Shell deeply rimate-umbilicate, ovate-conic, rather solid, 
under the lens spirally wavy-striate, glossy, pale buff rayed 
with darker streaks. Spire conic, rather acute. Whorls 5, 
convex, the last slightly shorter than the spire, subcompressed 
at the base. Columella simple, slightly arcuate. Aperture a 
little oblique, oblong, peristome white, glossy, rather widely 
expanded throughout, the margins converging, columellar 
margin spreading. Length 22 to 23, diam. 11 to 12 aperture 
with perist. 12 x 8.5 mm. (Pfr.).

In the Monographia Pfeiffer mentions a var. &, "a little 
more ventricose, rayed with isabelline 'and whitish." 

Figs. 5, 6, represents a specimen received from Cuming. 
This typical form of P. turneri has very pale narrow yellow- 
ish-green streaks on a white, faintly lemon tinted ground. 
There is a very inconspicuous band below the periphery. The 
base is markedly full, sack-like. The spiral lines are rather 
widely spaced and become very faint on the last half of the 
last whorl, except at the base. The figured example meas- 
ures, length 23.5, diam. 13.3, length of aperture 12.5, width 
8.9 mm. ; whorls 5%. Another of the same lot is smaller, 
length 23, aperture 12 x 8.5 mm. 

Var. perstrigata nov. PL 33, fig. 4. 

The shell is pale buff or whitish, copiously marked with 
narrow chestnut or pale chestnut streaks; form, size and 
sculpture as in turneri. 

One of the lots of this form, received from Dr. Hartman 
and said to have been collected by Geale, is marked "Tanna, 
New Hebrides." The type lot, no. 59848 A. N. S. P., was re- 
ceived from Cuming as "P. turneri var., New Caledonia", 
an evident error. The variety closely resembles P. caledonica 
in color, but it is much more robust. Cf. P. macgillivrayi. 


65. P. MACGILLIVRAYI Pfeiffer. PL 33, fig. 15, 16. 

Shell broadly and compressed umbilieate, conic, rather 
thin, striatulate and under a lens closely sculptured with 
spiral striae; whitish with yellowish streaks and marked with 
obsolete bands. Spire long-conic, rather acute. Whorls 5, 
slightly convex, the last about equal to the spire, somewhat 
ascending in front, sack-like at the base. Columella slightly 
arcuate, lightly folded deep within. Aperture slightly 
oblique, truncate-oblong; peristome white, thin, equally, sub- 
rectangularly expanded. Length 23, diam. 11, aperture with 
peristome 12.5x9.3 mm. (Pfr.).

67. P. NEMATORAPHE Pilsbry, n. sp. PI. 35, figs. 1, 2, 3. 

The shell is ovate-conic, rather thin, white under a thin, 
pale, yellowish green cuticle, which is darkest at the base, fad- 
ing upward to corneous- whitish on the upper whorls, the last 
whorl having narrow streaks of a darker shade at irregular 
intervals. Surface glossy. Embryonic shell -of fully 2y 2 
whorls is very minutely punctate-striate spirally; following 
whorls are more convex, with rather distinct oblique growth- 
strise but only very faint and fine traces of spiral lines, ex- 
cept on the last whorl, which is distinctly striate spirally on 
the base and somewhat malleate behind the outer lip. The 
last whorl is full, rather swollen above the periphery, then 
tapers to the narrow, very convex 'base. The umbilical chink 
is deep and ample. Whorls nearly 5%> separated by a well- 
impressed suture, which in the last two whorls is bordered 
above by a low cord defined by a groove. This margin is cov- 
ered by the ascent of the last whorl near the aperture, but 
may be traced faintly on the last whorl, though it is there 
very indistinct. The aperture is vertical, white within. 
Outer lip narrowly reflexed, white, thickened within. Colu- 
mellar margin broadly dilated above. The lip-callus extends 
somewhat more than half way up to the insertion, where it 
terminates in a small but distinct nodule. Parietal callus 
thin, transparent.

Partula alabastrina Pfr., H. H. SMITH, Annals of the Car- 
negie Museum, i, p. 468, no. 4293. 

This species was thought by Dr. Hartman to be P. alabas- 
trina, but Pfeiffer's description of that shell does not apply 
well to these specimens in several respects. Fig. 3 represents 
the suture just behind the aperture, showing the end of the 
suprasutural >cord. 

68. P. EXIMIA Hartman. PL 33, fig. 11. 

The shell is very deeply rimate-perforate, pyramidal. The 
unique type is a "dead" shell, denuded of cuticle, grayish 
white, but the color is preserved on the parietal wall, indicat- 
ing a very pale buff ground marked with narrow brownish- 
yellow streaks; the coloration perhaps intermediate between 
that of typical P. turneri and P. caledonica. The apical 
whorls resemble those of P. brazieri, though the second may be 
slightly more convex. Subsequent whorls are quite convex, 
and traces of fine, rather spaced spiral striation, just as in 
P. caledonica, may be seen on the penultimate and next earlier 
whorls, the last whorl being 'without spirals except around 
the umbilicus. Oblique growth-wrinkles are rather distinct. 
The last whorl is compressed laterally and very convex at 
the base. Aperture only half the total length, slightly 
oblique; perisitome white, expanded, well thickened within; 
having the usual deeply placed fold at the root of the colu- 
mella. Length 23, diam. 11.7, length of aperture 11.5 mm., 
width 7.8 mm. ; whorls 5%-

Partula eximia HARTMAN, Proc. A. N. S. Phila. 1886, p. 
35, pi. 2, f. 14. (April 6, 1886). 

This species stands very close to P. caledonica, from which 
it differs by the slightly more lengthened spire, and perhaps 
the paler, less brown color. Hartman, in 1896, wrote me 
that he considered eximia a synonym of macgillvrayi, having 


compared it with a Cumingian specimen of macgillivrayi 
in the Newcomb collection (see Nautilus XI, 1897, p. 44). 
According to the measurements given by Pfeiffer, macgil- 
livrayi has a larger aperture. The unique type of P. eximia 
is figured and described. 

69. P. EBURNEA Hartman. PL 33, fig. 8.

pressed. Columella wide above, lip reflected, white and flat, 
margins of the peritreme connected by callus. Color ivory- 
white. In fresh examples sometimes the whole shell is tinged 
with pale rose. Length 26, diameter 13, length of aperture

The shell is deeply rimate-umbilicate, rather thin, ovate-

indistinctly marked with narrow yellowish- green streaks on 
the last whorl. Spire slender, long. Embryonic whorls conic 
and but slightly convex, much as in P. brazieri. Subsequent 
whorls convex, the penultimate and last whorls very strongly 
convex. The later part of the last whorl is flattened laterally ; 
base very full, sack-like. Spiral lines well spaced on the 
penultimate whorl, wanting on the last except at the base. 


Aperture subvertical, white inside; peristome white, rather 
narrowly reflexed, thickened within, the columella dilated

In coloring, this species is like P. turneri except that it has. 
no band below the periphery ; but it is a much more slender 
shell with a deeper suture. It stands very close to P. eximia, 
but differs by the more swollen last whorl and consequently 
wider aperture, and by the greener color. Described and

251, pi. 13, f. 4. SMITH, Ann. Carnegie Mus. i, p. 467, no. 

Dr. Hartman 's description and a copy of his figure (fig. 9) 
are given. The specimens before me from Sitova Island (fig. 
10) are smaller, with a narrower lip than the Aura Island 
type. The apex is like that of P. brazieri-, later whorls are 


engraved with distinct spiral lines which are somewhat separ- 
ated on the penultimate whorl and front of the last one, but 
on the latter half of the last whorl the spiral striae are close, 
with deeper lines at short intervals. The later whorls are 
strongly convex, but the last becomes compressed laterally, 
towards the aperture, and is sack-like below. The umbilical 
chink is deep and wide. The color is a slightly bluish milky 
white, without markings. Length 21.8, diam. 12.2, length of 
aperture 11.2 mm.; whorls 5%. 

While it is closely related to P. caledonica, macgillivrayi, 
eximia etc., this species is distinct by the absence of color 
streaks and the persistence of spiral striae over the whole 
last whorl. 

I have been unable to find an Aura Island in the New 
Hebrides. Probably Arag is intended. Sitova is also un- 
known to me.

the spire, obliquely produced. Columella vertical, heavily 
calloused, broadly dilated above, especially over the umbilicus, 
transversely subsuloate. Aperture oblique, oblong, obliquely 
truncate behind. Peristome white, calloused, expanded and 
reflexed, slightly sinuated posteriorly. Length 20, diam. 10 
mm. (Pease).

"The habitat of -the above species is doubtful. From its 
approaching P. macgillivrayi, Pfr., and caledonica, Pfr., in- 
habiting the New Hebrides, and having lately received speci- 
mens from Dr. Jas. C. Cox, with other species from that group 
of islands, there is little doubt but that locality is -the correct 
one. It differs from the species mentioned above in being 


smaller, more 'slender, * sinistral, ' smooth, without any trace of 
transverse striae, and last whorl produced." (Pease).

conic. The last two whorls are whitish (probably denuded 
of cuticle) below the suture, elsewhere covered with a thin 
greenish yellow cuticle with some inconspicuous darker streaks. 
The spire lacks cuticle and is very pale brownish, almost 
white. Apex obtuse; embryonic whorls slightly convex, 
punctate-striate, not so high as in P. fraterna. Subsequent 
whorls more convex, sculptured with distinct, regular en- 
graved spirals, which are somewhat weaker and more widely 
spaced on the upper part of the last whorl, closer and deeper 
on the base. Last whorl is strongly convex, its last half 
however being perceptibly compressed laterally; base very 
convex. The aperture is but slightly oblique, symmetrically 
ovate, faintly flesh-tinted within. Peristome white, moder- 
ately reflexed, thickened within. Columellar margin dilated

250, pi. 13, f. 1. SYKES, Proc. Malac. Soc. Lond. v, 198. 

This is said to be a common species. It differs from P. 
fraterna chiefly by the better developed spiral striation, lower 
embryonic whorls and shorter spire ; yet it is not improbable 
that intermediate forms occur. 

An embryo of 2y 2 whorls, 4.9 mm. long, is figured, pi. 34, 
fig. 8. The first half whorl is pale brown and smooth, fol- 
lowing whorls are densely punctate-striate above. The peri- 


phery of the last whorl is angular, base with no spiral striae. 
The columella is long, vertical, rather heavily calloused, taper- 
ing and somewhat excised 'below, not unlike the columella 
in some forms of Obeliscus. The axis is perforated. 

Mr. Sykes states that 'the specimens from Do Island col- 
lected 'by Mr. J. J. Walker are a local race. 

74. P. PRATERNA Hartman. PL 34, fig. 4. 

The shell is rather widely and deeply rimate, solid, ovate- 
conic. Last whorl whitish below the suture, elsewhere cov- 
ered with a faintly green tinted yellow cuticle which is in- 
distinctly streaked with brighter yellow ; the spire brown, be- 
coming darker towards the apex;* suture well impressed, 
marked with a whitish line. Apex obtuse, the top more 
rounded and the sides less straightened than in P. caledomca, 
brazieri etc. ; embryonic whorls punctate-striate, convex ; sub- 
sequent whorls convex, engraved with rather delicate spirals, 
almost obsolete on the upper part of the last whorl, but dis- 
tinct though delicate on the base. The last whorl is a little 
flattened laterally behind the aperture, convex and somewhat 
sack-like basally. Aperture fleshy within, ovate, hardly 
oblique. Peristome rather narrowly expanded and -re-flexed, 
thickened within, tapering at the upper end. Columellar 
margin broadly reflexed, dilated and biramose above. Parietal 
callus thin, transparent, thickened at its junctions with the 
lip ends. 

Length 20.2, diam. 11.8, aperture 10.9 mm. ; whorls 5~y 3 .

This rather stout, opaque species has some resemblance to 
P. carnicolor, but differs by its shorter form, wider umbilical 
fissure and the much more convex base. The embryonic 
whorls are more convex than in the group of P. turneri, and 
the apex is more obtuse. It is closely related to P. auraniana 


but differs by the longer spire of decidedly over five whorls, 
while auraniana has barely five or fewer. The spiral striation 
is not nearly so well developed in fraterna, and the second 
whorl is higher. 

A second example in the type lot is 19 mm. long, but not 
quite fully mature. Description and figure are from the type,

75. P. CARNICOLOR Hartman. PL 34, figs. 1, 2, 3. 

The shell is oblong-conic, moderately solid, rather narrowly 
umbilicate ; fleshy-brown under a very thin yellowish-corneous 
cuticle <with narrow darker greenish-yellow streaks (the 
cuticle mostly wanting in the two adult cotypes, which were 
"dead" shells). Spire straightly conic. Embryonic shell 
rather large, conic, densely punctate-striate spirally, bicolored, 
the lower part of each whorl brown, darker than the upper. 
Subsequent whorls convex, marked with growth-lines but 
without spirals except at the base, which is very closely 
marked with wavy spiral striae. Last whorl is evenly convex 
throughout, tapering basally. Aperture ovate, oblique, flesh- 
tinted inside. Peristome narrowly expanded and reflexed, 
white on both face and reverse, well thickened within; colu- 
mellar margin dilated above, distinctly grooved at its 
junction with the whorl.

The specimens of this species were returned to Mr. Brazier

yellow cuticle, the spire light brown or white; suture indis- 
tinctly white-bordered. Spire conic, the apex obtuse; 2% 
embryonic whorls are convex, very delicately punctate-striate 
spirally. Following whorls convex, with sculpture of growth- 
lines and extremely delicate engraved spirals, which are in- 
distinct and rather widely spaced except on the 'base where 
they are closer and more distinct. The last whorl is some- 
what compressed laterally and very convex at the base which 
is rather narrow and sack-like. The aperture is symmetri- 
cally ovate, rather oblique. Peristome narrowly reflexed,

The two cotypes from Dr. Hartman's collection, no. 4243

ample is corneous with hardly any yellow tint. It is deciduous 
in spiral 'bands, not much remaining on the last whorl and 
none on the spire. The other example has a yellower, more 
persistent cuticle.

1 ' The above is of the type of P. repanda Pf r. inhabiting the 
same group of islands. It is smaller than that species, more 
abbreviate in shape, thinner, distinctly striate, columella no- 
dose, and of a different color." (Pse.). 

The figures are from >a specimen in the Hartman collection 
(no. 4244 Carnegie Mus.). It measures 13 mm. long, 8 wide, 
aperture 7.3 mm. long, and has 4^ whorls. It is bluish white, 
the spire pale brown. The columellar nodule, mentioned by- 
Pease, may be seen in fig. 9, under a lens. While smaller than 
Pease's type, I think the specimen is probably identified cor- 

I suspect 'that P. concinna was based on a stray example of 
P. tceniata nucleola. The description certainly favors that 
theory, and the Hartman example figured seems hardly separ- 
able from that Moorean shell.

"All the individuals of the division of Partulas are re- 
markable for the generally short aperture, the wide and 
strongly reflexed peristome and especially for the very deli- 
cate intersecting longitudinal and transverse striae. 

' ' This new species is solid, long, regularly ovoid. The aper- 
ture is ovate, a little contracted, with the peristome much 
expanded but only a little thickened within, tending to be-

base, partly covering the umbilicus which is oval and not deep. 
The spire is pointed, whorls wide, oblique, rounded, the last 
whorl, a little swollen, is larger than the others taken together. 
The suture is linear. The color of the shell is fawn, becom-

The shell is long ovate, moderately strong, white under a 
thin cuticle which is gray on the spire and base, yellowish- 
brown in the middle part of the last whorl, where there are 
very faint traces of spiral lighter and darker bands. The spire 
is rather long, whorls convex; suture well impressed. Just 
above the suture may be seen an inconspicuous ridge or angle 
the periphery of the penultimate whorl. The embryonic 
sculpture is worn; subsequent whorls have very even and 
regular spiral striation, which may be slightly weaker on the 
upper part of the last whorl. Last whorl is convex at first, 
on the last half becoming flattened laterally; very convex, 
sack-like, at the base. The umbilical fissure is short but deep. 
Aperture slightly oblique, ovate, small, white inside. Peris-

Two of the three cotypes in coll. Hartman (Carnegie Mus-

in calling the shell "flexuose." It is very closely related to 
the following species. Fig. 13 shows a portion of the last 
whorl a short distance behind the aperture.

corneous on the spire; rather openly but deeply umbilicate; 
sculptured 'throughout with impressed spiral lines. Whorls 
moderately convex, parted by impressed sutures which are 
usually margined above more or less distinctly. Last whorl 
is laterally flattened and saccate at the base. Aperture longer

This form stands extremely close to P. flexuosa, but it has 
a longer aperture and somewhat thinner shell. The umbilicus 
is also a little more open in hastula. I hardly think the two 
specifically distinct. Figures and description from the co- 
types, no. 4239 Carnegie Mus.

whorls are very minutely sculptured with spiral puncture- 
lines, the junction with the after- growth not distinct; whorls 
somewhat convex, separated by a well-impressed suture, which 
is narrowly bordered above, the border denned by an im- 
pressed line; last whorl is strongly compressed laterally, sac- 
cate at base, and a little concave just below the suture. Post- 
embryonic sculpture of strongly developed spiral striae and 
irregular growth-lines (very similar to that of P. regularis,

a narrow, weakly-marked band of the same at the periphery. 
Surface rather dull, with sculpture of weak growth- wrinkles 
and close, slightly rippled, deeply engraved spiral lines; at 
the peripheral band there is a group of finer spiral lines. 
Whorls 4%, convex, parted by a simple suture, which on 
the last half of the last whorl has a rather wide margin be- 
low, defined by an impressed line. The last whorl is rather 


convex, but tapers slightly toward the base. The aperture is 
slightly oblique, bluish- white inside. Peristome white; outer 
lip narrowly reflexed, thickened within, except at the strongly 
curved posterior part, Where it is thin. Columellar margin

In shape and sculpture this species resembles Partula re- 
gularis, but it differs by the very distinctly marginated suture, 
the less approaching terminations of the lip, the better de- 
veloped callus within the lip, and the coloration, which seems 
to be quite characteristic. It will probably be found to be 
.a species of the Solomon Island or the New Hebrides. 

This species was in the Hartman collection under the name 
"P. laevigata Pfr.," but on the label Dr. Hartman expressed 
the opinion that it was not that species. It has*little in com- 
mon with l&vigata, which evidently belongs to a wholly dif- 
ferent group. Named in honor of Dr. J. W. Holland, Director 
of the Oarnegie Museum.

The spire is shorter than that of P. similaris, with not quite 
5 whorls, the last one convex, shaped about as in similaris, 
being much less compressed laterally than P. coxi. The lip 
is only very slightly thickened within, much less than in 
coxi, similaris etc. The spiral striation is weaker on the 
last whorl than in the allied species. Color very pale honey 
yellow, slightly transparent. The suture is marked with a 
whitish line. Sometimes a margining thread may be seen 
above it on the last whorl, but in other shells this is con- 
cealed. The last half whorl is impressed just below 
suture, forming a sort of margination there.

and evenly developed on the last whorl, which is especially 
convex above the periphery and at the base, and somewhat 
tapering between. The aperture varies from moderately to 
very slightly oblique, ovate ; outer and basal lip narrowly re- 
flexed, slightly thickened within except at the posterior curve 
of the outer lip where it is thin; on the columellar side the 
thickening extends about half way up to the insertion. The 
columellar lip is dilated and two-branched above.

gracilior Pease in coll. according to Dr. Cox's label. 

This shell stands near P. pellucida Hartm. but differs by 
its longer, less obtuse spire. 

Utp to the beginning of the last whorl the shell is biconie, 
acutely angular or carinate at the periphery, the angle bear- 
ing a projecting cord wider than the other intervals of the 
spiral sculpture. The axis is perforate at all stages of 

P. micans has the last whorl less compressed laterally, and 
the lip is much less thickened within.

Shell oblong-ovate, narrowly perforate, thin, pellucid, 
granulose by the intersection of longitudinal and transverse 
striae. Spire conic. Suture impressed, margined. Whorls 
4%, plano-convex, the last hardly one-half tthe length of 
the s'hell. Aperture vertical, ovate. Peristome somewhat 
thickened, white, slightly expanded. Columella slightly di-

"It is. the nearest allied to P. minuta Pfr. It differs in 
being more slender, thinner, the spire elongate, the aperture 
smaller, the surface more distinctly granulose and the suture 
marginate" (Pease). 

One adult and two young examples in the Hartman collec- 
tion, no. 4246 Carnegie Museum, are stated on the label to 
'have been compared with "Brazier's type example." They 
are labelled "Ysabel, Solomon Is. (coll. Cox)." The adult 
shell is figured (fig. 6). It is white under a very^thm, clear 
corneous cuticle which is partly worn off in ragged streaks. 
The surface is rather coarsely sculptured with close wavy 


spirals, the intervals as -wide as the striae; embryonic sculp- 
ture indistinct, -being worn. Whorls 4%, convex, the latter 
part of the last whorl somewhat flattened laterally and ; 
slightly concave just below the suture, which is whitish. 
Aperture slightly oblique, oval; peristome continuous, the 
outer lip slightly expanded, thickened within except near 
the posterior 'angle ; parietal callus heavy for so small a shell, 
its edge distinctly raised. Umbilical chink short but deep. 
Length 11, diam. 6.9, aperture including peristome 6x4 mm. 

Another specimen (pi. 36, fig. 5) from Dr. Cox, (no. 59873 
A. N. S. P.), measures, length 11, diam. 6.7, aperture 6.5 mm. 
long. It is similar but has the corneous cuticle entire and 
the parietal callus weak in 'the middle. There is a narrow 
slightly prominent though hardly raised girdle at the peri- 
phery, where the cuticle is more persistent, 'and this is visible 
above the suture for a short distance behind the aperture. 
This structure is so weak that it might readily be overlooked, 
but it is visible in both of the examples seen. The aperture 
is decidedly oblique in this shell. 

This species has a shorter spire than the preceding forms 
and is a little smaller, otherwise they seem to be closely

"This species is more lengthened and especially more acute 
than the preceding [P. vanicorensis] ; the whorls of the spire 
are well spaced and separated by a quite deep suture; the 
last whorl, a little larger than the others together, is still but 


little inflated. The aperture is produced obliquely towards 
the right, and is ovate; peristome wide, but little thickened

A slender, acute pale species, of which I give the original 
description and figures (pi. 36, figs. 17, 18). These, if ac- 
curately drawn, indicate a shell with longer spire than any I 
have seen. Port Carteret examples before me received from 
Cuming (pi. 36, figs. 15, 16) are nearly white with the spire 
pale flesh-colored. The surface is glossy, with sculpture of 
growth- wrinkles and extremely fine and close engraved spirals. 
Above the periphery of the last whorl these spiral lines be- 
come faint, more or less obsolete. The apex is rather pointed. 
The last half of the last whorl is compressed laterally, the 
base saccate. The aperture is vertical, ovate ; the lip narrowly 
reflexed and thickened within, thin near the posterior angle, 
the outer margin slightly sinuous. The umbilical chink is 
rather small. 

Length 17%, diam. 8%, aperture 9x6 mm. ; whorls 5. 

Length 16, diam. 8%, aperture 8% x 6 mm. ; whorls 4y 2 . 

It differs from P. coxi, kubaryi etc. by the more delicate, 
more minute and crowded spiral lines of the penultimate 
whorl and base. 


93. P. KUBARYI Hartman. PI. 36, figs. 7, 8. 

The shell is ovate-conic, rather thin, openly rimate and 


narrowly, deeply, umbilicate ; pale grayish yellow, but slightly 
shining. Whorls 5, all moderately convex; 2% embryonic 
whorls are sculptured with delicate punctate spiral lines as 
usual ; following whorls have fine incised spiral lines through- 
out, strongest on the last whorl. The suture is impressed, 
and at its last turn is bordered 'above ; this border is narrow, 
and continued as a slightly differentiated belt on the last 
whorl, in front of the aperture. The last whorl is somewhat 
compressed laterally and full at the base. The aperture is 
slightly oblique, ovate, flesh-tinted inside ; lip white, narrowly 
reflexed, thickened within except at the upper curve where it 
is thin. Golumella dilated above. Length 14.8, diam. 8, 
aperture 7.2 x 5 mm.

This species stands near P. kubaryi, having almost the 
same contour, but" it differs by the very weak spiral striation. 
P. micans has a thinner lip and much more distinct sculpture.

"P. elongata Pease, and P. gracilis of the same author, from 
the Tahiti group, closely resemble this species. The former 
is rather larger and broader, not so strongly spirally striated, 
and more or less striped with pale brown. The latter has a 
longer aperture, rather more convex apical whorls, and a pecu- 
liar bulging at the lower part of the body- whorl. P. minuta, 
Pfr., also from the Admiralty Islands, is similarly sculptured, 
but of a totally distinct form." (E. A. Smith). 

Mr. Smith's description and figure (fig. 7) are copied. 
One of the specimens from Wild Island before me is smaller, 
length 14%, diam. 7, aperture 7.2 mm., with 5 whorls. The 
aperture of this example is quite oblique (pi. 37, fig. 6). In 
a larger specimen the aperture is almost vertical. The peri- 
pheral cord common to other species of the group is visible 
aJbove the suture, which is also very distinctly marginate be- 
low, on the last half whorl. Spiral striation is very dis- 
tinctly developed throughout.

Equally with Mr. Hedley (1. c.) I am unable to grasp any 


specific distinction between P. similaris and P. woodlarkiana. 
The type specimens of both were returned to Australia by 
Dr. Hartman. I have copied a photograph of the type of 
P. similaris in fig. 13. Specimens from the Trobriand Is. are 
also figured, pi. 37, figs. 14, 15. The shell is somewhat 
transparent grayish yellow, flesh-tinted near the apex. The 
surface is very distinctly and beautifully decussate, the deeply 
engraved spiral lines being made wavy by the fine, rather 
distinct growth-striae. The last whorl is convex, narrowly 
umbilicate, and sometimes margined below the suture on its 
last half. A narrow margining thread may be seen in places 
above the suture. The suture itself is edged throughout with 
a fine white line. The callous thickening within the lip thins 
out rather gradually above, not abruptly as in many related 
species, but it stops abruptly about half way up the 'eolu- 
mellar margin. At the 'columellar insertion there is a slight

P. woodlarkiana Hartman appears to have a somewhat 
larger aperture than similaris, but it is otherwise very like. 
A photograph of the type is copied in my figure 16, of plate 
37. The original description follows : 

"Shell dextral, ovate, thin and translucent; body- whorl

This species is more lengthened and thinner than any other 
known to me. The penultimate whorl is longer than in the 
species already mentioned [P. otaheitana, rufa, lineata, luted] . 
The last whorl, finally, is but little dilated, little swollen. 
The aperture is directed to the right. It is higher than wide, 
with the peristome thick, a little dilated in front of the um- 
bilical chink. The surface of the shell is very finely striate 
longitudinally and transversely, hence covered with a fine 
and granulose network. The 'aperture is white. All the

the mouth on the right side, large and oval, provided with a 
thick flange, the umbilicus very open back of the columellar 
plate adnate to the peristome. The spire is short, conic, ob- 
tuse at the apex, the whorls parted by a quite deep suture.

An unfigured species, not recognized since its description. 
So far as I know the Coquille landed only at Port Dorey 
(near Mt. Arfak and the N.-W. cape of Geelvink Bay), and 
probably this shell came from there. The visit was in July- 
August, 1824. Hartman, at one time, identified P. canalis 
as P. bulimoides. From Lesson's description, the shell must 
be very different from other species of the southwestern

of the genus.

Dr. Hartman has recorded the loss of the type of this 
species by shipwreck on its return voyage to Mr. Garrett at 
Tahiti. The figure is a copy of his. 

"I received this shell from Mr. Layard, through Mr. A. 
Garrett. In outline and general appearance it resembles some 
varieties of P. varia. I have named it in honor of Dr. 
Wesley Newcomb, one of our oldest . American conchologists, 
well known for his writings on the allied genus Ackatinella 
of the Sandwich Islands." (Hartm.) 


Straightly conic forms with high embryonic whorls and 
very deeply engraved later whorls, the last compressed later- 
ally and sack-like below, with a very ample umbilical area 
and deep perforation. The aperture is unusually long, and 
the peristome is thin and very broadly reflexed. Type 
P. thetis. 

The three closely related forms from Pelelu (Pililu) stand 
apart from all other Partulas. They have some appearance 
of being a branch from the Melanesian group. The coloring, 
the slight differention of a peripheral belt (marked with finer 
spiral striae), and the high apical whorls, recall species of 
the New Hebrides and Solomon Islands.

This third species, according to Semper, is not quite so thin 
as the other two. The aperture is a little rounder, and the 
summit is mamillate, a feature totally wanting in the two 
other species. 

A specimen before me, figs. 5, 6, no. 4272 Carnegie Mus., 
is distinctly streaked with greenish-corneous and whitish on 
the last whorl, growing ruddy on the spire. The apical 
whorls are very high, much -as in P. brazieri (pi. 33, fig. 2) . 
The rest of the whorls are very distinctly and beautifully 
sculptured with close, deeply engraved spiral lines. The lip 
is thin throughout, not perceptibly thickened within, and 
tapers rapidly from the upper third to the insertion. The 
columella is straight and vertical. Length 30, diam. 15,

A large, bulimoid species having much the appearance of a 
small Borus. Pfeiffer's type, figured in Philippi 's Abbil- 
dungen (copied in my fig. 9), is the rather obese form further 
illustrated -by figs. 7 and 8. The embryonic shell is very 
densely striate spirally but is usually worn in adult shells. 
The rest of the whorls have distinct spiral striae, which in the 
typical form are deeply engraved throughout, but on some 
examples they become rather weak on the last whorl. The 
ample aperture is dull purplish inside in some examples, white 
in others. The white lip is reflexed, and a little thickened 
within. The 'chestnut color of the shell is sometimes varied 
by a faintly darker line at the periphery. Examples measure : 

Length 27, diam. 18.3, aperture 16, x 11.8 mm.; whorls 5%. 

Length 27, diam. 17, aperture 15.5 x 11 mm. ; whorls S 1 /^. 

Length 28, diam. 17, aperture 15 x 12 mm. ; whorls 5%. 

The form called brumalis by Reeve (pi. 38, fig. 10, copied 


from Reeve) is somewhat more elongated, yet it intergrades 
fully with guamensis, judging from examples 'before me (see 
measurements above). The forms figured by von Martens 
from the ruins of Nanmatal belong to this more lengthened 
type. They further illustrate the variation in shape of aper- 
ture caused by the different degrees of inclination of the 
columella, and hence have been copied in my figs. 11, 12, 13, 
14 of pi. 38. 

Dr. von Martens gives the size as length 26, diam. 16, 
aperture 15 x 11 mm. 

Both Hartman and von Moellendorff have renamed this 
species, objecting to the name guamensis "inasmuch as this 
mollusk certainly does not live on the island of Guam, where 
my friend Quadras collected for more than two months with- 
out finding it" (Mlldff.) ; but if the name be rejected on that 
ground, the species should be called brumalis Rve. 

P. GUAMENSIS GRANDIS Moellendorff is "much larger, diam. 
19, alt. 30.5 mm., less solid, spiral sculpture somewhat less 
marked, peristome more expanded, less labiate ; 5% to nearly 
6 whorls. Ponape, coast region (Etscheid, Kubary). 

"There are three color- variations, viz., dark purple-brown 
with violet lip (typical) ; castanea, pale -chestnut colored with 
white lip ; and flavescens, pale greenish yellow. The last 
named albino is rather rare " (Mlldff.} . 

106. P. MARTENSIANA Pllsbry, n. sp. PI. 38, figs. 15, 16. 

The shell is ovate-conic, solid and strong, opaque, with a 
small, compressed umbilicus; beneath a yellow cuticle (which 
is partially lost from the type specimen, a "dead" shell), 
the substance of the shell is dull flesh color, becoming darker 
on the spire, the first three whorls being dull brownish purple. 
The spire is eonic, summit slightly obtuse; the early whorls 
are worn and show no sculpture ; last whorl has no spiral in- 
cised lines, but some traces of fine spiral wrinkling may be 
seen in places, though it is very fine and weak. Whorls 5, 
convex, the last convex throughout. Aperture is very slightly 
oblique, flesh-pink within; peristome white, very slightly ex- 


panded, strongly thickened within. Columellar margin di- 
lated above, deep within, as in P. guamensis. Length 22.3, 
diam. 14.1, aperture 12.1 x 9 mm.

Related to P. guamensis, from which it differs by the ab- 
sence of distinct spiral lines on the last whorl, the less ex- 
panded but more thickened lip and more contracted aperture. 
It was identified by Dr. Hartman with P. rufa Lesson, but 
that is a smaller, especially narrower shell. 

The type specimen was collected by John Brazier "on the 
banks of the Leila river, Chabroul Harbor, Ouhalan or 
Strong's Island," according to a letter from Brazier to Dr. 
Hartman, written at Sydney, June 18, 1885. 

A second specimen in the Hartman collection measures, 
length 21.5, dram. 14, aperture 11.7 mm. It is an old shell, 
faded and broken. 

107. P. RUFA Lesson. 

This species resembles especially the preceding [P. ota- 
heitana] , but the aperture is turned to the right. The spire is 
less lengthened, more swollen, more conic. The last whorl is 
proportionally larger.' The aperture is more oval and less 
contracted, and its peristome is not so thick. The color is 
dirty red. Length 8, diam. 4 lines (Lesson).

Lesson's brief description indicates >a shell resembling 
P. guamensis in general features, but much smaller than any 
other known species of the group, about 16 or 17 mm. long, 
8 or 9 wide. It is hardly possible that the identifications of 
P. rufa made by either Hartman or* von Martens are correct. 
This was also the opinion of Dr. O. von Moellendorff. P. rufa 
still awaits rediscovery. 


Group of P. lineata. 
108. P. LINEATA Lesson. PL 39, figs. 19, 20. 

The shell of this species is oval, long, with conic spire, a 
half whorl swollen. The aperture opens on the right side. 
It is contracted by a thick rim recurved backward, and di- 
lated at its junction with the columellar axis, a little in ad- 
vance of the umbilical crevice. It is nearly of the same size 
and shape as the 0-Taite Partula [P. otaheitana] , but it is 
constantly -a little shorter and more inflated. The color is 
pale yellow with two ribbon-like stripes of fawn, one short, 
surrounding the opening of the umbilicus, the other running 
around the middle of the large (last) whorl, and covered 
by the suture on the spire. Length 8, diam. 5 lines (about 
16x10 mm.). (Lesson).

This species was 'considered the same as P. suturalis Pfr., of 
Moorea, Society Islands, by Mr. Garrett in his paper of 1884, 
but later he doubted the identification, in a letter written to 
Dr. Hartman. Mr. Brazier, who visited Ualan, did not find 
Lesson's species (H. H. Smith, Ann. Carnegie Museum i, p. 

The general appearance of the shell is that of a Society Island 
species; but the Coquille did not visit the island of Moorea 
where the forms (P. suturalis, P. taniata) best agreeing with 
Lesson's description occur, but only Tahiti and Borabora, ob- 
taining P. otaheitana at the former, P. lutea at the latter 
place. They were at Ualan in the Carolines on June 15th, 
1824, anchoring in Coquille Harbor on the N.-W. side of the 

In view of the general reliability of the locality records 
in the Zoology of the Coquille, and the imperfection of our 
knowledge of the shells of Ualan, I think it not improbable 
that P. lineata may eventually be found there. 


The nodule on the parietal wall, shown in Lesson's figure 
but not mentioned in the description, is a feature appearing 
also in species of the Society, Fiji and Marianne groups. 
The relationships of the species are obscure. I would not 
venture to assign it to any of the subgenera.

Ferussac's type of P. gibba was a small, short example. 
His figure is copied (pi. 39, fig. 1). The last whorl is pale 
yellowish-corneous, spire of a rather peculiar dull scarlet 


color. The last three whorls have an opaque white 'border be- 
low the suture. The last whorl varies in the degree of swell- 
ing, and in small individuals is usually angular in front, at 
the periphery; base very full and convex. Umbilicus small 
and deep, more rounded than usual in Partula. The engraved 
spiral lines are distinct and not very close above the periphery, 
more crowded on the base. The aperture is oblique, white in- 
side in the pale, variously colored in the dark varieties. The 
peristome is white, or in some forms flesh-tinted. The outer 
lip is expanded, rather heavily thickened within, the callus 
somewhat abruptly terminating at the beginning of the curve 
to the upper insertion; columellar lip dilated. Pigs. 2, 3, 
5 and 6 represent individuals of the typical P. gibba. Be- 
sides the typical coloration (a) described above, there are 
shells with (&) reddish spire and brown last whorl (fig. 2), 
and others (c) of the typical pale tint and a white spire (fig. 
9). These forms occur together in some lots before me. 
Other forms are: 

(d) Corneous-white, somewhat transparent, very thin (pi. 
39, fig. 11). 

(e) Drab with the spire dull dark purple, lip fleshy (fig. 7). 
(/) Lilac, the spire darker, aperture brown within (fig. 8). 
(g) Light reddish-brown (fig. 5). 

(h) First 2y 2 whorls bicolored, brown and whitish, the rest 
corneous-yellow, becoming dull purple near the lip. Interior 
lilac, with a brown streak within the lip, which is flesh-colored 
(fig. 10). 

There is considerable variation in the solidity of the shell, 
and the thickness of the lip-callus. The latter is sometimes 
perceptibly nodulous, as in fig. 6. 

To what extent the variations in color and texture are local 
or racial is unknown. All have a white sutural border. Ex- 
amples measure as follows : 

(a) Length 17, diam. 11.3, aperture 9.8 mm. long. 

(d) Length 17, diam. 12, aperture 10 mm. long. 

(e) Length 15%, diam. 11, aperture 9 mm. long. 

(/) Length 18~y 2 , diam. 12%, aperture, 10 mm. long. 


(h) Length 18%, diam. 13, aperture 11 mm. long. 

Specimens of a lot consisting of rather solid shells of forms 
~b and g show a thin callus or low tubercle on the parietal 
wall, approaching P. bicolor in this respect (figs. 5, 6). 

P. mastersi Pfr. seems to be identical with gibba, judging" 
from the description and specimens before me. It is de- 
scribed as rather solid, buff, fleshy or violaceous, sometimes 
banded with brown on the upper whorls. It is 17 mm. long, 
with the aperture 10% mm. 

109a. P. GIBBA BICOLOR Pease. PI. 39, figs. 12 to 18.

Peristome brownish outside and within. Whorls 4, convex,, 
the last half the length of the shell. Peristome thickened, 
narrowly and equally expanded. Aperture slightly oblique, 
oval, with a small callus deep within on the belly of the penul- 
timate whorl. Length 15, diam. 9 mm. ; aperture 5 mm. long,. 
4 mm. wide (Pease).

Partula bicolor PSE., Amer. Journ. of Conch, vii, p. 26, pL 
9, f. 4 (August 1,1871). 

The above may be distinguished from P. gibbet,, which occurs 
at the same locality, in being of smaller size, last w^orl not 
inflated, and in its color (Pse.). 

This form inter grades with P. gibba, and should evidently 
be regarded as a subspecies of that, chiefly distinguished by 
having the last whorl less swollen than in typical gibba, and 
by having a callous nodule deep within, on the parietal wall 
near the columella. This nodule is seen very weakly de- 
veloped in some examples of gibba. Other supposed differ- 
ences are even less constant. 

Pease's original description reproduced above is not good; 
his figure is copied, pi. 39, fig. 17. The shell is rather solid, 
with sculpture of spiral lines as in P. gibba. On the last 
whorl these lines are very fine and close on the base, but a 


little more separated above the periphery. The surface is 
-glossy. The lip may be narrow and nearly uniform in width, 
.but usually it is rather strongly thickened inside, the callus 
.abruptly discontinued near the posterior curve. The color 
of the lip is quite variable. There is a callous nodule deep 
within, near the columella, but it is very variable in size. 
The suture may be marked with a whitish line, but often this 
is absent. No specimen I have seen has a well developed 
white band along the suture, such as is usual in P. gibba 
'The color-patterns known are as follows: 

(a) Straw colored or isabelline, with a reddish-brown band 
above the suture almost to its end, and covering the first 
13/2 whorls; outer half of the lip brown, inner rim 
white. This is the typical coloration (figs. 12). 

(b) First 2 whorls purplish-brown, the third pale below the 
.suture with the dark color fading (or the subsutural 
pale area may extend nearly to the apex) ; last 2 whorls 
straw yellow or pale isabelline with faint or distinct 
brownish streaks; back of lip reddish or yellow; lip 
narrow, very pale brown; surface rather dull (fig. 18). 

(c) Same as the last but without brown on the spire; sur- 
face lusterless (fig. 15, 16). 

{d) Pale uniform sulphur-yellow throughout, the lip 

brown- tinted or brown-edged (fig. 14). 
^(e) Pale sulphur-yellow, the lip heavily thickened and 

pure white (fig. 13). 
The size varies as follows : 

(a) Length 17, diam. 11.5, aperture 10 mm.; whorls 4%. 

(b) Length 17, diam. 11, aperture 9.5 mm.; whorls 

(d) Length 16, diam. 11, aperture 9.4 mm.; whorls 

(c) Length 15.7, diam. 10, aperture 9.1 mm. ; whorls

tumid in front. Columella short, shortly receding. Aper- 
ture obliquely oval, glossy inside, yellow; peristome simple, 
thin, white, expanded, the right margin somewhat straight- 
ened, columellar margin dilated above, spreading above the 
umbilicus. Length 19, diam. 10, aperture 9x5 mm. inside

This form was at first supposed to be from New Ireland, 
but was soon shown to come from Guam. It is a narrowly 
umbilicate, thin shell, copiously striped with corneous and 
opaque white, with more or less suffusion of pale lemon yel- 
low. In the more fully colored examples there are also many 
olive-yellow lines among the stripes, scarcely visible except 
under a lens. These lines dilate at the periphery, which 
therefore, appears to have a faint band. This pattern is 
shown in fig. 4. Other examples lack the dark lines and 
peripheral band. The embryonic shell is very densely and 
distinctly engraved spirally, the lines disappearing towards 
the apex ; the first whorl is weakly plicate radially. The last 
whorl is marked with rather widely spaced spiral lines, closer 
on the base. In the typical form these lines are rather weak. 
The last whorl is very full at the base. The lip is white, 
narrowly reflexed, very little thickened within. Specimens 
measure : 

Length 19, diam. 11.2, aperture 11 x 7.1 mm. ; whorls 4y 2 . 

Length 17.5, diam. 11, aperture 10 x 7 mm. ; whorls 4%. 

Length 17, diam. 10, aperture 9.5 x 7 mm. ; whorls 4%. 

Length 16, diam. 9.9, aperture 10 x 7 mm. ; whorls 4%. 

A form (pi. 41, fig. 2) collected by Quadras is smaller, with 
a brown band above the suture on the first 2y 2 or 3 whorls 
of some specimens, the spire in others being pale lemon tinted. 
The last whorl has the typical coloration. The aperture is 
more or less brown inside in those with a dark summit. The 
first whorl does not seem to be plicate.

marginal teeth resembling those of Partula, yet differing by 
the larger size of the second cusp, whereas in Partula the inner 
cusp is the larger. The central tooth has no side-cusps. 
There are 160 rows of 40,6,1,6,40 teeth. If the pallial organs 
etc., confirm the relationship claimed by Hedley (but which I 
doubt) this species will form a new genus of Partulidce, char- 
acterized by the unexpanded, thin and simple lip of the shell, 
and the absence of the typical apical sculpture of Partula.
