The description of Orthurethrous snails is continued in this
volume, the remaining groups of Ferussacidcs 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.

INTRODUCTION.
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 Suc-
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 (Pupillidce, Valloniidce, Ferus-
sacidce), 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,
Achatinellidce and Tornatellinidtf comprise the most con-
spicuous elements of the snail-fauna.
The following families are now comprised in the group
Orthurethra :
Valloniidaj (See Vol. VIII, p. 247, and IX, p. 282).
Holarctic.
Enidae (Buliminidcz of authors). Palaearctic, Oriental,
African.

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 C. 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 Miill. Distribution, Europe and most tropi-
cal and subtropical countries.
An excellent account of Csecilioides 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 progressk n
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
and down the front of the head are two mucus sulcations on
cither 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).
C^CILIOIDES. 3
" 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 Cydostoma
elegans and Helix pomatia seem sensitive to the approach of a
large object." (Lionel E. Adams in The Journal of Conchol-
Vol. 9, p. 207.)
4 (LECILIOIDES.
Caecilioides 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.
odeida" (Journ. of Conch, iii, 1882, p. 317). In North-
amptonshire Messrs. Wright and Adams found C<zcilioi,des
abundant to a depth of 4^ 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 Caecilioides is wanting,
but they probably feed upon vegetable matter, such as subter-
ranean fungi or possibly fine rootlets.
The European species of Ceedlioides 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
overloaded.
The generic name has been variously spelled, but the earliest
C-iKCILIOIDKS. O
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 Cxcifioides, having for type the
same species, C. acicula.
Csecilioides occurs in typical species in the Miocene and Plio-
cene, the following species being known. All were described
under the name Csecilianella.

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.

very indistinctly curved; spire long subconic-cylindric, the apex
obtuse; suture very oblique, distinctly margined. Whorls 6£,
flat, the middle ones long. Aperture ehort-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.).

"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." (Wollaston).
This species apparently belongs to the section Rhaphidiella of
Maltzan. See species No. 6.

This species is distinguished from C. 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
"species " are really the same I do not know. Fig. 32 repre-

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
variation.

Var. anglica Bgt. According to Bourguignat, this is dis-

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.

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,

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

form aperture. (Ben.)

small, piriform. Columellar callus rather thin, but in certain

Bielz intended his name to replace that of acicula, but he
gave a description of the Transsylvanian form, which proves to
be distinct from ancula by its greater elongation. It stands
close to Uesvillel, 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.

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

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. vandalitia 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 belonidsea.
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 belonidsea, 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. bdonidcea. 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.

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

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 rcgularh- 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,

The identity of this species, and its synonymy, have been the
subjects of considerable variance. Unfortunately I have not

specie;?. 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 Ku ester. 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 aciculoldes, just as veneta seems to be a derivative of
adciila. 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, fusiform-cylindric, acicular, the apex attenuate,
obtuse, hyaline, glossy, white or gray. Whorls nearly fiat;
suture very narrowly margined; columella arcuate, the base
narrowly truncate. Aperture ovate-oblong, lanceolate, very
narrow; peristome simple, unexpanded, acute. Length 3.5 to
4, diam. 1 to 1.25 mm.; whorls 6 (dc Betta, 1852).

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.

form, 3.7 x 1.2 mm. It is very similar to 0. petitiana, from
which it differs in little but the smaller size, in specimens of
apparently equal age. It is practically identical with C. rizzeana,
though the mouth may be a thought narrower, in the specimens
compared. The Madeiran C. nyctelia is conchologically not
distinguishable.

From specimens before me from Benoit. this does not seem
to differ materially from G. petitiana except in being smaller.
I have figured a Benoit shell measuring 4.4x 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.

last nearly flat, longer than the spire. Columella subarcuate,
abruptly truncate at the base. Aperture lanceolate, narrow.

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 H 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 columella is concave, has a callous edge, and is
obliquely but quite distinctly truncate at the base. Length
4.3, diam. 1.3mm.; whorls 5.

According to Mousson, there are fewer whorls than in C.
acicula ; 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. subsaxano Bgt. . which perhaps may be a young
form of the same species.

"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 ite congeners of the
Alpic center."
Paladilhe probably had two species mixed in his lot of C.
isseli. The description is that of a Ctzcilioides, possibly identical
with Nevill's second species (Handlist Ind. Mus. p. 162),
and with A. balanus of Hanley and Theobald (Conchologin,
38 OX'ILIOIDEK OF TROPICAL AMERICA.
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. (Geostilbio.') balanus. Further investigation of
the Csecilioides 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, Went Indies, etc.
Tropical countries have a few species of Csecilioides 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
Geostilbia.

The type lot at Amherst consists of three specimens. It is a
C.ECILIOIDES OF TROPICAL AMERICA. 39
Bubcylindric shell, obtuse at both ends, of scarcely four whorls
in most examples, 4-| 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:
Cotype, Adams coll.: length 1.75, diam. .5 mm.

Fig. 71: length 2, diam. 0.6, aperture 0.75 mm.
Fig. 67: length 1.65, diam. 0.5, aperture 0.75 mm.
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 Gonchylien Cabinet is very
poor. It shows no columellar truncation, and hence C. 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. pygmcea 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. pygmcea follows.
"A. pygmcea Ph. Shell cylindric, smooth, pellucid hyaline,
the apex rather obtuse. Whorls 5, rather flattened, separated
by an oblique, lightly impressed suture, the last \ 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." (P/r.)

the base, the strise appearing crimped or waved (fig. 79).
There is no other difference. Specimens measure:

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

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
wall.
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 P.
acicula 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

Two specimens from Noumea are drawn in figures 58, 59, 62,

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 is
not positively known. No description of even these specimens
has appeared, and Swainson' s figures are extremely crude.

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, /. c. ).
Nevill also refers the species to Geostilbia. In his description of
<'. 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 speciea
involved. Fig. 60 is copied from Reeve's type figure. I have
also copied the figure given in f^onehologia Indica, pi. 4, fig. 61.
By its strongly truncate columella, this figure seems to cor-
respond with the description of C. Isseli.

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.
GLESSULA. 51
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
AchatiiKi. 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
about 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
regions.
Glessula was associated with " Cionelld, " (that is, the Ferus-
mcidce as herein understood) by Professor von Martens in 1860.
Various other authors, both before and since, have thought the
group Aehatinoid, 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 llagellum) at the end of the penis is a feature
unlike any Achati.nida. 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 Glesmla to Subulina, Homorua,
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 ^mall 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 SubvJina. 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 chiefly contributed to the literature. Blanford's
">'2 GLESSULA.
"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
IndicM. Finally, Colonel R. H. Beddome has recently reviewed
the genus in his "Notes on Indian and Ceylonese Species of
Glessula."
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-
Bribed. 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 Ceecilioides (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 first 2£ whorls seem to be nearly smooth, but with a
finely crenulate suture; then fine, distinct strise begin, strongest
near the suture, weaker below. On the spire these stria? are
separated into groups by occasional deeper grooves or larger
striae; 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.

"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. areas 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
convex.

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, subvertieally and
not very deeply truncate at the base.
Length 8.5 to 8.8, diam. 3.2, aperture 3 mm. ; whorls 6y2.
Ceylon: Kandookerre (E. L. Layard).
This form was distributed by Layard as packycheilus 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 6y2 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.

This species is very close to G. nitcx*. 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
smaller.

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!/2 to 13,

Compared with 0. 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.

length, slightly tapering at the base, rounded. Aperture ver-
tical, semioval; peristome unexpanded, thin, acute; the right

This minute form has about the size of a TornatelUna, 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.

'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.)

"The nearest ally to this species appears to be (}. tamulica
( \V. & II. 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
(i. hebes in being longer and slightly more attenuate towards
the apex. It has 13 whorls." (Blanf.}
"Ten specimens received from Blanford and E vizard, col-
lected near Poona, are all young, with quite unformed lip ;
and all the types of hebcs 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 sliiplayi. It runs the
young of that species rather closely, but the apex is gener-
ally blunter. Specimens collected by me on the Shevaroys
iire 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 sliiplayi. 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.)

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 striae 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^ 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.

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 2y2 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."

by the shape of the spire which is more convex at the side,
by its smaller breadth compared with its length, and by its

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

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.

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.)
"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).

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.)
Col. Beddome gives the localities, Assam; Arakan; Garo
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
lip."

Nevill under the name used above; they may possibly be
Glessula no. 80 of his Handlist, since they seem related to
G. subfusiformis.

Mr. G. Nevill has expressed the opinion that the form fig-

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 Blanf ord, which it perhaps
even more closely resembles, in general aspect at any rate,

"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."

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 strige and grooves in the intervals, but
quite unequally developed. The suture is crenulate. On the
last whorl or two some traces of spiral striae appear, in places.

of rather close grooves, most prominent at the suture, which is
rather deeply impressed, though the whorls are only moder-

" 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 '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
follows.
G. cornea Boettger. (PI. 14, fig. 3.) Shell not rimate,
subfusiform-turrite, rather solid, very glossy, bright chestnut-
brown, the apex not paler. Spire has very slightly convex
sides, apex exactly turrited, rather obtuse. Whorls 8, con-
vex, separated by a simple, impressed suture; minutely but
very distinctly, somewhat irregularly striate, the strias gath-
ered into groups at the suture and almost rib-like; last
whorl slightly tapering basally. Aperture subvertical, emar-
ginate-piriform subeffuse at the base, somewhat lipped with
violaceous inside, less than one-third the total length; mar-

VII. West African species.
Two quite distinct groups of Glessula are represented in
West Africa. The group of G. l&vigata 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. Icevigata.
The central teeth of G. Icsvigata 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. L^VIGATA (Pfeiffer). PI. 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.
(P/V.).
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.).

Voy. Welwitsch, p. 77. — Glessula lavigata PFR., Nomencl. p.
330. — Homorus 1., 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-striee, 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 6l/2.
Length 17, diam. 6.3, aperture 6 mm.; whorls Qy2.
Length 16.5, diam. 5.7, aperture 6 mm. ; whorls 6l/2.
88. G. HYALINA (Rang). PI. 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). PI. 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. (Gld.).

This species is viviparous. The summit is semiglobular ;
first 11/2 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 2y2 whorls they reach nearly to the suture below, and
become so close that the sculpture may be described as rib-
WEST AFRICAN GLESSULA. 109
striate, 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^.
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 assinicnsis, 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.

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 G1/^, 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

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.

BULIMULnXE.
G-enus HEMIBULIMUS Marts., Vol. XII, p. 184.
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
HEMIBULIMUS. 115
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.
1. HEMIBULIMUS EXCISUS (v. Marts.) Vol. XII, p. 185, pi.
36a, figs. 31-34.
Popayan, Colombia, at 2400 meters. Type species of Hemi-
bulimus. While evidently related to dennisoni, it is prob-
ably distinct, at least varietally, as Mr. Smith believes. In
Vol. XII I followed Professor von Martens in uniting excisus
and magnificus.
2. HEMIBULIMUS DENNISONI (Reeve). PI. 40, fig. 1.
"Shell fusiformly ovate, spire rather acuminated, whorls
6, somewhat rudely faintly plicately striated, decussated with
fine impressed striae. Apex somewhat papillary. Columella
arched and twisted, attenuately truncated. Pale brown, varie-
gated towards the apex with darker brown, last whorl un-
spotted, encircled with a pale obscure band, columella pink-
ish." (Reeve}.

PILSBRY, Man. Con. xii, pi. 36 a, fig. 30 (not the description).
Reeve described and figured a shell from the Dennison col-
lection. The present location of the type is unknown. The
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
116 HEMffiULIMUS.
and figure, the sculpture is not so strong as in the following
form; yet it must be remembered that the sculpture is usu-
ally minimized in Reeve's figures of Achatina.
H. D. CARUS Pils., n. var. PI. 40, figs. 2, 3, 4, 6.
The shell is elliptic-ovate with a rather slender spire and
obtuse apex; solid and strong. Nearly 2y2 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 plicae cut by several (usually
5 to 7) spiral furrows, which appear as if scratched in a
plastic surface. On the last whorl the fine plicae 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 black, 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. (&) 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 ochraceoua
reddish, the red predominating on the earlier whorls; outer
HEMIBULIMUS. 117
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.
Length 68, diam. 32 mm. ; aperture 37.5 mm. ; whorls 6*4.
Length 65, diam. 34.5 mm. ; aperture 38 mm. ; whorls 6.
Length 65.5, diam. 31 mm.; aperture 37 mm.; whorls 6.
Length 62, diam. 29.5 mm. ; aperture 33 mm. ; whorls 6^.

Achatina magnified, REEVE, Conch. Icon. V, pi. 9, f. 33. —
L. magnificus Pfr., PILSBRY, Man. Conch. XII, pi. 36a, f. 30.
Not A. magnified Pfr.
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)
represents a form differing from this race only in size, as
Mr. E. A. Smith has pointed out. In the Manual I fol-
lowed Reeve's error in referring to it as an illustration of
Achatina magnifica Pfr.
3. HEMIBULIMUS MAGNIFICUS (Pfr.). PI. 40, fig. 5.
See Vol. XII, p. 185, where a translation of Pfeiffer's
description is given. From the reference-paragraph there
given the reference to Reeve's figure should be excluded, and
the following added: Liguus (Hemibulimus) magnificus
(Pfr.), E. A. SMITH, Proc. Malac. Soc. London VII, 1907;
p. 314, fig. of type. This species seems to be known only by
the original specimen, said to be from Quito. Mr. Smith's
figure of this is copied on my plate. The specimens obtained
•by Lehmann in southern Colombia may have been H.
dennisoni.
ACHATINA MONILE Swainson. "Shell very finely reticu-
lated, whitish with waved stripes, and transverse bands of
chestnut spots ; basal volution subventricose ; spire produced,
118 HEMIBULIMUS.
the last two volutions close, and the tip papillary ; base nearly
entire. Distinct from, though approximating to, Bulinus
zebra and undatus,"
(Swainson, Catalogue of the rare and valuable shells which
formed the celebrated collection of the late Mrs. Bligh, Ap-
pendix, p. 14, 1822 ; Exotic Conchology, edit. 2, p. 38, 1841) .
This seems to be some such shell as Oxystyla ferussaci, or
some of the forms represented on plate 17 of vol. XII ; yet the
"apex papillary" recalls Pseudotrochus (Perideris) .

PARTULID^E. 155
Family PARTULID^E Pilsibry.
Partulidce PILS., Proc. Acad. Nat. Sci. Phila. 1900, p. 564.
Orthurethra in which the kidney is triangular, equal to the
pericardium in length. Genitalia of the haplogonous type,
the penis without an appendix. Shell Buliuioid, with the
outer lip expanded or reflexed in known forms; the eolumellar
lip reflexed, curving into the basal margin, simple or nodu-
lous; parietal wall often dentate, but the aperture never has
entering lamellae
Jaw very thin, formed of many narrow flat plaits, converg-
ing downward towards the middle. Radula broad; the cen-
tral tooth is not much smaller than the laterals, and has a
long middle and small side cusps; lateral teeth with the
mesocone long, ectocone well developed, but no entocone;
marginal teeth oblique with three cusps directed outward, the
inner one largest.
Distribution entirely insular, confined to high islands of
the southern and western Pacific. Nearly all the species are
arboreal, living on trees and bushes, but some species of
Raiatea, Tahaa, Tahiti and perhaps the Caroline Islands, are
terrestrial.
This family is co-extensive with the following genus.

156 PARTULA.
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 Heynernann, 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, recluziana, 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-
breviata, 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 Bulimulidcu or Helicidcs;
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 labial 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.
PARTULA. 157
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 attenuata,
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 dots (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
unknown.
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 Drymczus
and Zaplagius, formed by the union of many narrow delicate
158 PARTULA.
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 num'ber 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 mesocone 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 abbreviata, amanda, otaheitana; 8 or
9 in varia, umbilicata, virginea, bilineata, kyalina, 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
PARTULA. 159
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. fusca, 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 Partulidc?.
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,
160 PARTULA.
Ferussacidce, Amastrida and Achatinellidce, all of which
have the kidney very long, far exceeding the pericar-
dium. For comparison I figure the pallial region of Ena
reiniana (Bidiminus 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 En-idce are similar, yet the spirally striate em-
bryonic whorls are unlike that family, and are an invariable
feature of Partulidce, 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 Partulidce
stand somewhat isolated. There is no family of Bulimoid
or Achatinoid Orthurethra which can be said to be nearer
than any other to the Partidida, so far as present informa-
tion goes.
Hybridism.
In dealing with Society Island species both Mr. G-arrett
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. Garrett
writes as follows: " Hybrids between P. elongata and P.
tceniata, 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. tceniata ; about a dozen between the arboreal
PARTULA.
161
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 Raiatean species mentioned as hybrid-
izing by Garrett 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
assO'ciation of forms or the conditions of their existence.
Some general considerations bearing upon variation may how-
ever be in order.
162 PARTULA.
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 Ampliidromus, Liguus, Hemitrochus, Polymita,
Drymccus 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," whereby patterns characteristic of species or phyla
become in part or entirely latent in individuals or races.
Cf. the Pentata-nmte snails, Drymcuus, Ampliidromus etc.
Some species of Partula, such as P. liyalina, 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
PARTULA. 163
valleys. The topographic barriers (ridges unsuitable for
Partula?) 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 Partuke in the
Tahitian valleys are isolated very much as. are the Achati-
nellidas 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 Dracaena 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."

The reference of these forms to Partula is purely fanciful.
The American species is referable to a genus of Bulimulidre,
Hyperaidax. Well-preserved specimens have not the char-
acteristic apical sculpture of all known Partulidge. 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 Partulae. The Eocene
forms in question have not been shown to have the embryonic
sculpture of Partula.
Classification of Partulidce.
This family contains the single genus Partula. It is quite
possible that when the forms of Micronesia, Melanesia etc.
PARTULA. 165
are investigated anatomically, a further generic division
may foe 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
m 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
Partula 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 Partulas into numerous sub-
genera which seem to me superfluous. The subgenera 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^/2) 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.
166 PARTULA.
63. Fiji Is. This is the only group having raised spiral
sculpture.
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
Partulas 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-
PARTULA. 167
age. Their distribution is what would be 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 7 to 50.
III. Austral and Hervey Islands, species 9, 52.
IV. Samoan Islands, species 53 to 60.
V. Fiji Is., Kotuma 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.

Partulas 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
conchologically. 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.

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 2y2 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 sivollen
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-

The very thin cuticle is more or less wholly lost in most
adult shells. The examples described are from the island of

either entirely lost, or only a belt remains at and below the
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 2y2 whorls, coarsely
pitted in spiral lines except the smoothish initial half whorl.
Whorls 4%, convex, the last evenly rounded. The aperture is

Garrett istated 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.
172 PARTULA, MARQUESAS ISLANDS.
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 he 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).
&. White, covered with a very thin straw, cream or brown
tinted cuticle, the spire often corneous (fig. 15).
c. Rusty brown, having a whitish belt below the suture (fig.
16).
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 nun., 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
Nukahiva.

The shell is openly umbilicate, acutely long-ovate, solid, the
typical form -white under a very thin, very pale green cuticle,

straightly conic, whorls 5*4 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

tinted towards the summit, with a pale border below the

band just below the periphery. This band is sometimes very
inconspicuous. Old shells lose much of the cuticle, becom-

This very delicate snail is related to P. decussatula Pfr., 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 Hartrnan
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.
II. SPECIES OF THE SOCIETY ISLANDS.
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=y2 whorls,
very thin, fragile and subtranslucent ; color pale and
176 PARTULA, SOCIETY ISLANDS.
simple; aperture ample, peristome expanded, not thick-
ened. Section Leptopartula, species 7 and 8.
II. Shell composed of more than 4.y2 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 Partulae 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 of 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
species.

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
'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-

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 4^2, convex, the last very large, evenly
swollen. Aperture oblique, broadly ovate, two-thirds the

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 Tahiti an and
Raiatean types respectively ; 'but the entire series is so closely
interrelated that the named subgenerie divisions proposed by
Dr. Hartman cannot be sustained.
A small group of white, translucent species includes
No. 9, P. hyalina Brod. Tahiti, Hervey and Austral
Islands.
No. 16, P. clara Pse. Tahiti.
No. 17, P. attenuata 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. Partulce 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, producta 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. otaheitana, which has its centre of distribution
180 PARTULA, TAHITI.
in Fa.utaua 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. hyalina 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." (Garrett).
Numerous forms of Tahiti and Moorea are sinistral. The
species of all the other islands are invariably dextral. Sin-
istral Partulae also occur in the Samoan group.

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.

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. !!%» aperture 12 mm., whorls 5%.
Length 191/2, diam. IQi/o, 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. a/finis, 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. G-arrett
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. affiuis (no.

"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 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 common. ' ' (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 Pautaua 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-
tained.
' ' 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:

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

wore 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

G-arrett'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
nodosa.
Dr. Mayer found lignaria streaked without spiral bands,
and also with one dark peripheral band in Tipasrui valley.
All were dextral. In a few there is an additional subsutural
band.
In Hamuta and Pirae Valleys, a form with sutural, peri-
pheral and umbilical bands was found, constituting 3 to 4
per cent of the Partulcc caken. It occurred with streaked
Lignaria. In Pirse, all are sinistral; in Hamuta (between
Piras and Tipoerui) both dextral and sinistral individuals were
found.

"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.

"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 Partulce 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."

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 affinis 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) .

colored with darker and lighter oblique streaks, which may be
called variety confluens (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 eause 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.

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

Tahiti : ' ' This beautiful arboreal species is restricted to a
limited area about two miles up Punaavia valley on the west

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.
PARTULA, TAHITI. 195
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. PI. 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 Grarrett 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 I1/-*
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).

' ' 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 veiy 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 case 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.

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. attenuata
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 livar., 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.

to its peculiar habit of living on the foliage near the tops of

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
200 PARTULA, MOOREA.
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
attenuata.
In a lot or 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 Partula.
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 :

the white expanded lip is rather thin and moderately incras-

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."

The original figures of this species are copied, pi. 27, figs.
10, 11. It was described from the Curning 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 2y2 whorls are isabella-colored ; the darker ob-
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
PARTULA, MOOREA. 203
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 Garrett '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 Garrett 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
to in 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.
"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 p rob-ably, 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 8^2 x
6% mm., inside 3% mm. wide. Admiralty Is." (P. strigosa

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. ll1/^, 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. taniata and elongata.
PARTULA, MOOREA. 205
' ' 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 tvestern 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. mooreana."

Tlie 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
(jarrett writes, "varies from abbreviate-ovate to elongate-
ovate, more or less solid, scarcely shining, smooth or wrin-
kled with incremental strige, 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 whorl 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 stri gallons, 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 Morch's type, which he incorrectly as-
signs to the Viti Islands."
"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 oi 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.
PARTULA, MOOREA. 207
' ' On the -southwest part of the island we find tceniata 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 tceniata 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.
stngosa, only. But after passing Oahumi, the home of the
latter variety, we again find tceniata, 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 tceniata.
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 stngosa. Here, again,
it insensibly graduates into the typical tceniata. 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).

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. t&niata; and the
figure certainly lias 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 t&niata.
PI. 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. PI. 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 drawto 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.
PARTULA, MOOREA. 209
Another race, tangent from nucleola, is figured, pi. 27, fig.
7. The dark brown shell is profusely striped on the last l1/^
whorls with cream-white. The columellar denticle is small
and prominent.
P. T.ENIATA NUCLEOLA 'Pease' Garrett. PI. 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-°;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
tceniata. It stands very close to P. filosa of Tahiti. The two
are apparently of common origin. According to Garrett,
nucleola intergrades with tccniata, yet it appears to be as
distinct as elongata is. The largest examples measure 18 x
10, apert. 9 y2 mm. It lives in a small valley about two miles
west of Opunohu.

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.
Fig. 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.

"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 tcrniata.
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).

This form seems to intergrade perfectly with P. taeniata,
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 tceniata. 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."
The type lot received from Pease contains three shells
measuring
Length 18.5, diam. 9, aperture 9.3 mm., 5 whorls.
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 taniata and its allies. The whorls are not very convex,
last one more or less flattened below the periphery, very con-
212 PARTULA, MOOREA.
vex at base. The lip is narrowly reflexed, a little thickened
within. There is no noticeable callous nodule on the colu-
inella, 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 G-arrett (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. tceniata, in color, having two widely separated whitish
bands on a tawny-brown ground.

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 curved
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
PARTULA, RAIATEA AND TAHAA. 213
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 Partulae 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.
attenudta (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 liebe 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 Partulge known to be terrestrial are from Raiatea and
Tahaa, The terrestrial habit is no doubt a readaptation of
arboreal ancestors. The eoloration approximates to the dull
tints of ground snails.
214 PARTULA, RAIATEA AND TAHAA.
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.

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. imperforata raiatensis
and virginea are apparently the least modified survivors of
the original stock.

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. 12y2 mm. Fig. 3 repre-
sents one of the specimens sent by Mr. Pease as megastoma.

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 compacta Pse., from which it
differs by the parietal tooth. Description and figure from
Reeve.
24. P. DENTIFERA Pfeiffer. PI. 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!/2, 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
211/4, 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-ivhite, 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.

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,

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 Fatimu,
or on the southwest part of Raiatea. It occurs 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).

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
220 PARTULA, RAIATEA AND TAHAA.
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.
"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 strige and closely set delicate
spiral incised lines, which are more or less evanescent on the

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 y2, flatly convex,
the last one convex, or convexly rounded. Aperture sub-
vertical, oblong, obaurif orm, 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; eolumellar 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 on the columella
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
222 PARTULA, RAIATEA AND TAHAA.
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.

"Shell compressly umbilicated, solid, oblong-conic, some-
what shining, yellowish corneous or light fulvous brown;
spire convexly conical, half the length of the shell; suture

aperture subvertical, oblong, obauriform, rounded below and
much contracted by the strongly labiated peristome ; parietal
wall with a white tubercular tooth which is rarely absent;
peristome white, sometimes tinged with carnelian, widely ex-
panded, subplanulate, slightly contracted above, and the mar-
gins frequently nearly united by a ridge of callus; colu-
mellar lip vertical, more or less distinctly nodose. Length

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
PARTULA, RAIATEA AND TAHAA.
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 faba series.

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.
PARTULA, RAIATEA AND TAHAA. 225
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. hebe. 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 Grar-
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. PI. 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
226 PARTULA, RAIATEA AND TAHAA.
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
within.
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 lugiibris. 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).
6. 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.

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 ha.ving 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 sinuate d or weakly nodose with-
in; in oblique view less 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.

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.

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. PL 21, figs. 15 to 19.
The shell is minutely rimate or imperforate, oblong-ovate,
solid and strong, slightly shining, lightly marked with
growth-strife 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

Differs from the related P. thalia and P. nistica 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."

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.

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 strias. 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-color. In fig. 11 it shows one of the
common color-patterns of the faba group. Figs. 13, 14 rep-

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
Hartman 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.

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 20y2
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 Garrett 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, diani. 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 ot 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.

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 Partula?, 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).

PARTULA, RAIATEA AND TAHAA. 239
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, fiat, 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

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. Garrett 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 varidbilis 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. PUSCA 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-

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 IS1/!* 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.
(Garrett).
' 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).
242 PARTULA, RAIATEA AND TAHAA.
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 fused 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.

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

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.

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 ivhorl 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

"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.

body- whorl and a revolving band below the whitish subsutural
border, deep chestnut-brown. Not infrequent.

tinct oblique streaks. Rare.
Numerous specimens from Pease and G-arrett show it to
be rather constant in form, but some shells show an angle on
the last whorl, in front of the aperture. Garrett writes:
"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."

except for a light equatorial girdle or zone. The aperture is

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.

P. auriculata has been united by many authors with the
totally different P. otaheitana 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.

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 l1/^ 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.

zone above the middle of the last whorl. This pattern
also occurs in auriculata.

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 Raiatea.
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
250 PARTULA, HUAHEINE.
dentated species, which are so common in all the islands ex-
cept Borabora, 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. sir.

PARTULA, HUAHEINE. 251
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 (bicolor 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
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
252 PARTULA, HUAHEINE.
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 Pfr. 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 ; under 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 central
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
features.
2, form purpurascens Pfr. Dull purple, the aperture and
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

white (figs. 8, 9). According to Garrett this form is very
abundant.
6, form zotiata. 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
i9.5 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 estalliana '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. rosea follows:
"Shell ovate-pyramidal, roseate; whorls 6, longitudinally
substriate, subdecussate with very close lines, the last larg-
est; epidermis thin. Length %, diam. y$ 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).

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

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 2y2 whorls purple-brown or blackish
violet.
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 17.2, diam. 11, aperture 10 mm.
Length 17.4, diam. 11, aperture 9y2 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."

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 foe found, to
be a form of the otaheitana series from Tahiti.

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; peristoine white, the right margin somewhat
spreading above, moderately expanded ; columellar margin

This Partula is distinguished from P. varia by its swollen
shape, obtuse summit, wider, less oblique and more rounded
aperture, and finally the less thickened, less dilated peris-
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.
50. P. DIMINUTA C. B. Adams.
"Shell rather thick, ovate-conic; translucent, horn-colored,
sometimes reddish, with a thin shining brownish horn-colored
epidermis, which is much interrupted by transverse stripes ;
with the tip white, with unequal, irregular, rather coarse
transverse stride, and numerous excessively minute impressed
spiral lines; apex subacute; spire rather short, with the out-
lines slightly curvilinear; whorls five, a little convex, with a
moderately impressed suture ; last whorl moderately oblique :
aperture rather small, subovate, with a tubercle on the middle
of the intruding part of the last whorl: lip much thickened,
but narrow, with a regularly rounded surface: umbilicus
small." (Ad.).

fourths the length of the shell, somewhat inflated and pro-
duced obliquely, rounded at base, spire short, conical, rather
acute; aperture oblique, ovate; lip widely flatly expanded,

The figure does not agree well with Pease's measurements.
"We have no locality for the above species. It appears to
approach the Marquesau type, and may be allied to lilacina
Pfr. It is covered with a thin epidermis, which, when worn
oft', would probably leave the shell without color, as is the
case with ganymedes, Pfr. We have but a single specimen. ' '
(Pease.)
III. PARTUL^E OF THE AUSTRAL AND HERVEY GROUPS.
The few species of these groups are very closely related to
those of the Society Islands, and no doubt are of common
derivation.
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
PARTULA, HERVEY IS. 261
has stated that the Baiatean P. liebe 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. 2% 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-
lated above.
Length 18.3, diam. 10.5, aperture 10 mm. ; whorls 5.
Length 17.2, diam. 10, aperture 9.3 mm. ; whorls 4^.

(name only).
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. Barotonga."
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 Barotonga.
262 PARTULA, SAMOAN ISLANDS.
IV. PARTITIVE OF THE SAMOAN ISLANDS.
The Samoan Partulas 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
follows.

A single specimen before me (pi. 32, fig. 8) has a much
shorter spire than canal-is, 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.

The shell is sinistral, openly umbilieate, conic, with rather
slender spire ; white under the thin yellow cuticle, the earlier
whorls and a subsutural margin being white. The surface
is glossy. Whorls 5%, the first half-whorl smooth, follow-
ing 2~y2 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
Lcrvus 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*4 to 51/^) , 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

brown on the spire, suture edged with a white line. The
embryonic whorls, except the first half-whorl, are deeply and
very closely sculptured with engraved punctate spirals (pi.
31, fig. 12) ; following whorls and upper half of last whorl
have rather widely spaced spiral lines, and the basal half of
the last whorl is densely marked with wavy spirals. Spire
short, conic, regular. Whorls 5*4, convex, the last equally
convex except near the aperture where it is a little produced
outwardly towards the base. Aperture ample, flesh colored

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
wliich 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.

that P. brazieri inhabits the Samoan Islands ; yet up to this

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 ivhorls; 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

whorl or two, fading to whitish above near the suture, the
spire whitish. The spiral striae 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

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 creiiulated

276 PARTULA, NEW HEBRIDES.
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
place.

VI. NEW HEBRIDES AND SANTA CRUZ ISLANDS.
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 Partulse. 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. Many of the islands are high and wooded.

This typical form of P. turneri has very pale narrow yellow-

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

ceived from Cuming as "P. turneri var., New Caledonia", —
an evident error. The variety closely resembles P. caledonica

A slender shell resembling P. turneri in coloration. The
spiral lines are distinct and rather widely spaced on the
penultimate whorl and obsolete on the last whorl except in
the base. There is a faint band below the periphery, as in
the allied species. The apical whorls are shaped like those

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 2y2
whorls is very minutely punctate-striate spirally; following
whorls are more convex, with rather distinct oblique growth-
strias 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 o1/^, 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.

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. PI. 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; peristome 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%.

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.

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

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. Golumella vertical, heavily
calloused, broadly dilated above, especially over the umbilicus,
transversely subsulcate. Aperture oblique, oblong, obliquely

73. P. AURANIANA Hartman. PL 34, figs. 7, 8, 9, 10.
The shell is deeply rirnate, rather thin but solid, ovate-
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,
punc'tate-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-

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 intermediaite forms occur.
An embryo of 2i/> whorls, 4.9 mm. long, is figured, pi. 34,

pliery of the last whorl is angular, base with no spiral striae.
The columella is long, vertical, rather heavily calloused, taper-

Mr. Sykes states that the specimens from Lo Island col-

The shell is rather widely and deeply rimate, solid, ovate-

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. caledonica,
brazicri 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 reflexed,
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.

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

while auraniana has barely five or fewer. The spiral striation
is not nearly so well developed in fraterna, and the second
whorl is higher.

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

' ' 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-
rectly.
I suspect that P. concinna was based on a stray example of
P. taniata nucleola. The description certainly favors that
theory, and the Hartman example figured seems hardly separ-
able from that Moorean shell.

The Solomon Island Partulee are corneous or pale yellowish
or greenish corneous forms, plain and simple in shape and
coloring.
81. P. FLEXUOSA Hartman. PI. 35, figs. 4, 5, 13.
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 danker 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-
tome well expanded, thickened within, white, columellar mar-
gin dilated above, and slightly grooved where it joins the
preceding whorl. Parietal callus transparent.

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.
82. P. HASTULA Hartman. PI. 35, figs. 6, 7, 8.
Shell similar to P. flexuosa, ovate-fusiform, thin, covered
with a thin cuticle, pale yellow on the last whorl, grayish-
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
than in P. flexuosa; outer lip thin, reflexed, thickened with-

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 defined 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,
fig. 11) ; behind the outer lip the surface is opaque and often
of a brighter yellow tint. Aperture ovate, hardly oblique,
bluish white within. Peristome reflexed, thickened within
except near the upper angle where it is thin. Columellar mar-
gin oblique, dilated above. Parietal callus thin.

Partula incurvum HARTMAN, Proc. A. N. S. Phila. 1886,

By its strong spiral sculpture this species is close to P.
regularis, but it is more lengthened than that, with less con-
vex whorls, the last one more flattened laterally and more
sack-like below. P. hastula resembles incurva, but it is far
less strongly sculptured. Description and figures from the
type, no. 4240 Carnegie Museum.
84. P. REGULARIS Hartman. PL 35, figs. 11, 14.
The shell is ovate-conic, rather thin, nearly lusterless, of
a pale gray-buff tint. Sculpture of close, strongly developed
spiral striae as wide as 'their intervals, (pi. 35, fig. 11, last
whorl behind aperture x 25) . Spire conic, the whorl rather
convex; last half of the last whorl is a little compressed
laterally, and the base is very convex ; umbilicus deep, rather
open. Aperture oval, bluish- white within ; peristome thin, re-
flexed, thickened within except near the upper end.
Length 17, diam. 9.8, aperture 9 mm. ; whorls 5%.

''Partula laevigata Pfr.," H. H. SMITH, Ann. Oarnegie
Mus. i, p. 452, no. 4237.
In shape and sculpture this species resembles Partula re-
yiilaris, 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 Icuvigata, which evidently belongs to a wholly dif-
ferent group. Named in honor of Dr. J. W. Holland, Director
of the Carnegie Museum.

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 the
suture, forming a sort of margination there.

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

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. 8y2, aperture 9x6 mm. ; whorls 5.

PARTULA, LOUISIADE ISLANDS.
"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 141/2, 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
above the suture, which is also very distinctly marginate be-
low, on the last half whorl. Spiral striation is very dis-
tinctly developed throughout.

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 colu-
mellar margin. At the columellar insertion there is a slight
groove.
Length 18, diam. 10, aperture 9.4 x 6.7 mm. ; whorls 5.
Length 16.8, diam. 9.2, aperture 9 mm. ; whorls 5.
P. tvoodlarkiana Hartman appears to have a somewhat
larger aperture than similaris, but it is otherwise veiy like.
A photograph of the type is copied in my figure 16, of plate

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, rufd, lineata, lutea] .
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
rest is uniform light gray. Length 8, diam. 3!/o lines

This Partula is the largest species known to us. It is 10
lines long and 7 in diameter. The shell is thick, solid, with
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-

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
Pacific.

XI. PELEW ISLAND SPECIES. Section PALAOPARTULA n. sect.
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 timbilical 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 strias), 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,
aperture 16.2x10 mm., including peristome; 6 whorls.

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 5l/3.
Length 27, diam. 17, aperture 15.5 x 11 mm. ; whorls 5y2.
Length 28, diam. 17, aperture 15 x 12 mm. ; whorls 5y2.
The form called brumalis by Reeve (pi. 38, fig. 10, copied
310 PARTULA, CAROLINE ISLANDS.
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 Pilsbry, 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 conic, 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,

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, diam. 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. 0. von Moellendorff. P. rufa
still awaits rediscovery.

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.
446).
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. t&niata) 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
island.
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.

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
314 PARTULA, MARIANNE ISLANDS.
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. Figs. 2, 3,
5 and 6 represent individuals of the typical P. gib'ba. Be-
sides the typical coloration (a) described above, there are
shells with (6) 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).
(/O First 21/) whorls foi colored, 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 IS1/^, diam. 11, aperture 9 mm. long.

PARTULA, MARIANNE ISLANDS. 315
(/i) Length IS1/^, 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.
Shell solid, perforate, acutely ovate, glossy, transversely
marked with close obsolete stria? ; straw-colored, the whorls of
the spire encircled with a brownish band next to the suture.
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}.

9, f. 4 (August 1, 1871).
The above may be distinguished from P. gibba, which occurs
at the same locality, in being of smaller size, last whorl not
inflated, and in its color (Pse.).
This form intergrades 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
li/o whorls; outer half of the lip brown, inner rim
white. This is the typical coloration (figs. 12).
(&) 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%.
{&) Length 17, diam. 11, aperture 9.5 mm.; whorls 4i/o.
(d) Length 16, diam. 11, aperture 9.4 mm.; whorls 41/4.
(c) Length 15.7, diam. 10, aperture 9.1 mm.; whorls 4y2.
110. P. RADIOLATA (Pfeiffer). PI. 41, figs. 1, 2, 3, 4.
Shell subperf orate, oblong-tapering, the apex obtuse, thin;
sculptured with distant impressed spiral lines; pale straw-
colored, rayed with darker streaks and brown lines. 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
iimbilicate, 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
Length 17.5, diam. 11, aperture 10 x 7 mm. ; whorls
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 2y2 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.

P. radiolata rushi, n. var., pi. 41, fig. 1. Dr. W. H. Rush
collected examples much darker in color at Port San Luis
d'Apra, Guam (no. 84841 A. N. S.). The last iy2 whorls are
striped with cream and dark brown, with a narrow but con-
tinuous brown peripheral band. The spire is uniform dark
brown, aperture brown within. Sculpture typical. Length
15, diam. 9, aperture 8.8 mm. (pi. 41, fig. 1).
111. P. QUADRASI Moellendorff.
Shell dextral, narrowly and half-covered perforate, rather
ventricose ovate-conic, very thin, pellucid, delicately striatu-
late transversely, decussated by closely crowded spiral lines;
a little shining, pale buff variegated with narrow darker and
whitish streaks, sometimes ornamented with two indistinct
bands. Spire subregularly conic, the apex somewhat obtuse.
Whorls 4, a little convex, separated by an appressed, mar-
gined suture, the last whorl quite convex, nearly tumid. Aper-
ture rather oblique, oval, a little excised; peristome simple,
thin, well expanded, the columella dilated above, recurved,
forming a distinct angle, almost channeled, with the parietal
wall. Length 15, diam. 10.5, aperture 9x7 mm. (Mlldff.)

An unfigured species which seems to differ from the small
form of P. radiolata in sculpture and by having fewer whorls.
It is possibly identical with Ferussac's P. fragilis, a lost
species which has not been figured. The description follows :
P. fragilis Ferussac. Shell ovate-elongate, perforate,
fragile, striatulate, pellucid, reddish; spire obtuse, sutures
strongly marked. Whorls 4, the last ventricose, subcarinate,
larger than the rest. Aperture ovate, peristome subreflexed.

XIV. SNAILS OF OTHER GENERA DESCRIBED AS PARTULAE.
Partula acuticosta, consimilis and lamellicosta, Journ. A.
N. S. Phila. ix, 113, are errors for Patula a., c. and I.
Partula auricula Fer., 1821 = Auriculella.
Partula australis Bowdich 1822 = Strophocheilus.
Partula batavitf Grateloup, 1840, = Amphidromus adamsi
var. rubiginosus Fulton (Proc. Malac. Soc. London viii, 44).
Partula delatouri Hartm. = Diplomorpha, Vol. xiii, 118.
Partula dumartroyi Souleyet = Auriculella.
Partula flavescens King, 1831 = Bulimulus chilensis Less.
Man. Conch. XI, p. 8.
Partula glaber Hartman, Proc. A. N. S. Phila. 1885, p. 205,
is Drymaus strigatus Sowb., color-form purus. See MANUAL
XI, p. 228. The type specimen of glaber, no. 4291 Carnegie
Museum, agrees exactly \vith the Peruvian shell, but the
internal lilac lip-border, though still noticeable, has faded.
Partula layardi Braz., llartm. is a Diplomorpha, Vol. xiii,
p. 116.
Bulimus macleayi Brazier from Yule Island, other islands
in Torres Strait, and Queensland, was described as a Papuina
in this Manual, Vol. XIII, p. 121. It has been referred by
Hedley to Partula (Proc. Linn. Soc. N. S. Wales ix, 1894, p.
387, pi. 26, f. 22, 23) ; the radula figured by him has
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.

P. 287. The name Partula minor Hartman might by some
be considered unavailable on account of the earlier B. roseus

intended the word minor as a description, not as a name.
