upper portion of the body-whorl, suture with opaque white and
chestnut spots ; lip moderately thick, denticulated within.

Length, 10 mill.

Southern Australia.

A somewhat variable shell both in form and coloring, as shown
by numerous specimens before me. I agree with the Australian
conchologists that C. albomaculata , Angas (fig. 62) is a synonym.

C. ALBUGINOSA, Reeve. PL 51, fig. 3.

Shell ovate, smooth, shining, transparent white, reticulated
with orange-brown, with a central light band ; whorls flatly
convex, the last somewhat twisted and grooved ; aperture small,
lip simple, slightly notched at the upper part. Length, 10 mill.

Habitat unknown.

The type of this species formed part of the Taylor collection.

C. INTERRUPTA, Gaskoin. PL 51, fig. 64.

Shell ovate, attenuated at both ends, rather solid, white,
encircled above and below by bands of crescent-shaped chestnut
spots ; spire somewhat turreted, whorls encircled by a groove
round the upper part, the body-whorl deeply grooved towards
the base ; aperture rather narrow, lip slightly notched at the upper
part, denticulated within. Length, 10 mill.

Habitat unknown (Taylor collection).

C. ABYSSICOLA, Brazier. PL 51, fig. 65.

Shell oblong, pyramidal, smooth ; whorls eight, flatly convex,


round shouldered ; yellowish white, spirally encircled on the
periphery with yellowish brown broad arrow-shaped markings, the
points showing to the right, marked as four arrows placed one
behind the other, opaque between, every alternate space arrow-
shaped, last whorl below having the markings more numerous
and close-set ; aperture oblong ovate, white, canal narrow, short,
peristome thickened in the middle, strongly denticulated within.

Length, 3 '5 mill.

North Australia, New Guinea (Brazier).

I figure an example of this elegant little species from one of
several specimens obligingly communicated by its author.

C. CINCINNATA, von Martens. PI. 51, fig. 66.

Shell smooth, oblong, shining, grayish white, with narrow,
longitudinal undulating chestnut lines, and maculations of
opaque white, in a double series ; apex rose-violet ; outer lip

without teeth ? Length, 3 mill.

Probably not adult.

C. ASOPIS, Duclos. PI. 51, fig. 61.

Shell smooth, yellowish, irregularly and openly reticulated by
light chestnut ; lip externally thickened, dentate within ; coin-

mella rugose.

Habitat unknown.

The figures of this unrecognized species are evidently greatly
magnified, but, like all the others upon the same plate there is
no accompanying size-mark.

Section V. Atilia, IT. and A. Adams.

Shell fusiform, smooth or longitudinally plicate ; spire elevated,
sharp ; last whorl suddenty narrowed into a beak or short canal
in front.

C. MINOR, Scacchi. PI. 51, fig. 68.

Shell smooth, striated at the base; yellowish brown, more or
less indistinctly marbled with a darker color, with sometimes a
light band on the periphery ; outer lip slightly dentate within.

Length, 9-12 mill.

Mediterranean Sea.

C. NYMPHA, Kiener. PI. 51, fig. 69.

Shell elongated,- smooth, striate at the base; yellowish, with


longitudinal chestnut lines ; aperture yellowish within, the outer
lip stained brown and denticulated on the inner margin.

Length, 12'5 mill.

Seychelles Is.
C. FILICINCTA, Tapparone-Canefri.

Shell acicular, contracted and striate at the base ; pallid
fulvous, with longitudinal darker strigations, and a band of
articulated fulvous and white on the periphery ; aperture narrow,

fulvous, the outer lip thickened. Length, 9 mill.

New Guinea.

Described from a single specimen and not figured. The
description brings it very close to C. nympha.

C. ARTJCULATA, Souverbie. PI. 51, fig. 70.

Shell yellowish, with curved longitudinal darker strigations
and an articulated band of chestnut and white spots on the
periphery which is apparent on the spire-whorls ; outer lip
emarginate above, acute, varicose externally, dark margined and

plicate within. Length, 10'5 mill.

New Caledonia.

Only a single specimen obtained. The coloring is very close
to that of the last species. I suspect that it is only a variety of
G. nympha.

C. MINDOROENSIS, Gaskoin. PL 51, figs. 71, 72.

Shell ivory-like, smooth, striate below ; whitish, with narrow
flexuous zigzag chestnut lines ; lip slightly dentate within.
Length, 10 mill.

Puerto Galero, Isl. of Hinder o, Philippines, in coarse

sand, at a depth of about 12 fathoms (Cuming).

Persian Gulf (Issel).
C. Doriae, Issel (fig. 72) appears to be a synonym.

C. BACULUS, Reeve. PL 52, fig. 73.

Shell solid, with flattened whorls and obtusely angulated
periphery, below which the body-whorl has revolving striae ;
whitish filleted and spotted with orange or chestnut, sometimes
showing a row of spots on the periphery ; outer lip thickened,

plicate within.

144 ATIL1A.

tudinal plications, the lower part of the body-whorl with revolving
striae ; whitish, marbled with yellowish brown. Length, 10 mill.

Port Lloyd, Bonin Islands (Stirapson).

I give a figure from a specimen in the Philadelphia collection,
received from Stimpson.

C. PLUTONIDA, Duclos. PL 52, fig. 75.

Shell whitish, with obscure chestnut or slate colored reticula-
tions. Length, 7 mill.

Habitat unknown-.

Figured by Duclos, with name, but no description.

C. PRETRII, Duclos. PI. 52, fig. 76.

Whorls flattened, with deeply impressed sutures, longitudi-
nally plicate ; white, broadly banded with chestnut, lower part

of body-whorl chestnut. Length, 7*5 mill.

Habitat unknown.
Figured, but not described by Duclos.

C. IONTHA, Ravenel.

Shell fusiform, strong, small, with nine flat, longitudinally
ribbed whorls, and deeply channeled sutures ; lower part of
body-whorl with revolving strise, which upon the ribs give place
to revolving colored lines and clouds ; outer lip considerably
enlarged, sparsely denticulated within ; aperture small, rather
wide, the pillar lip much hollowed above, suddenly becoming-
straight to form the canal. Length, 6+ mill.

Charleston Bar, So. Carolina.

A single specimen from the stomach of a black-fish. Is very
probably synonymous with C. Hotessieri, d'Orb., and C. Pretrii,
Duclos. In the event of their proving identical, the latter name
must be adopted, having priority of publication.

C. HOTESSIERI, d'Orb. PI. 52, fig. 82.

Shell oblong, thick, with wide longitudinal plications and
revolving strise; spire sharp, composed of seven, flat whorls,
separated by a crenulated suture ; mouth narrow, sinuous, the
thickened lip six-tuberculate, the columella slightly folded ;
yellowish white, more or less marked with chestnut.

Length, 7 mill.

Guadeloupe, West Indies.
See remarks under preceding species.


C. CONSPERSA, Gask. PI. 52, figs. 77-81.

Spire and upper part of body-whorl more or less obsoletely
and distantly plicate ; white, marbled and reticulated with
chestnut, forming a white band at the suture and another on
the periphery; body-whorl strongly contracted, with revolving
striae below ; lip externally varicose, dentate within, the margin
sinuous behind ; columella conspicuously folded, the upper fold
largest; canal recurved. Length, 12-15 mill.

Philippines, N. E. Australia, New Caledonia, Andaman Is.

The original figures of C. iodostoma, Gask. (fig. 78), and G.
puella, Sowb. (fig. 79), are more strongly plicate and darker
colored than man}' of the specimens before rne, yet they are
undoubtedly synonymous with the smooth form of C. conspersa,
from which the original figure and description of that species
were made. I add a figure from a specimen (fig. 80) of a nearly
smooth example, showing a usual state of the species. C. con-
taminata, Gask. (fig. 81), is to be referred here.

C. SUGILLATA, Reeve. PI. 52, fig. 86.

Shell ovate, livid brown or purple, spire turreted, whorls tuber-
cularly ribbed round the upper part, tubercles white ; aperture
somewhat squarely ovate, lip slightly varicose, angled at the
upper part, denticulated within. Length, 12 mill.

China Seas, Philippines.

C. SAGITTA, Gaskoin. PI. 52, figs. 83-85.

Shell narrow, smooth, shining; pale brown, longitudinally
strigated, maculated or reticulated with chestnut, with usually
a band on the periphery and sometimes another at the suture,
articulated with white and chestnut, sometimes sagittiform.

Length, 8 mill.

Sandwich Islands, Paumotus, Viti Islands, Solomon's Is.

This species was described as from Africa and West Indies,
but these habitats have not been confirmed ; on the other hand
the description applies closely to a common Polynesian species,
and this identification is concurred in by a number of concholo-
gists. The only figure of the species hitherto given is by Reeve ;
it is a poor representation of the usual state of the shell besides
being three times its size without any mention of its having
been enlarged. I give this figure, however (fig. 83). Pease de-

146 ATI LI A.

scribed it as 0. pusilla, and finding that name preoccupied
changed it to C. fusiformis, which was also preoccupied five or
six times by different authors. G. galaxias, Reeve (fig. 84), is
a synonym; as is also probably C. doliolum, Tapparone, an
unfigured species from New Guinea. C. Carolina, E. A. Smith,
from Strong Island, Solomon Archipelago, is exactly equivalent
to the figure of G. galaxias, Reeve ; my specimens being part of
the original lot of Garolinae. Mr. Smith's figure (fig. 85) does
not agree with his description.

C. MERITA, Brazier.

Shell thin, acicular, much contracted at the base, yellowish
white; whorls eight or nine, flattened, minutely tabled at the
suture, ornamented with roundish opaque white spots, below the
suture and between the spots two narrow transverse reddish
yellow lines one above the other ; the lower having longitudinal
lines of the same color running down, divided with a white band
on the centre of the last whorl, spire very much lengthened,
aperture pear-shaped, peristome thin, sinus at upper part, colu-
mella varicose, canal short, narrow. L. 7, diam. -J-5 mill.
Darnley 7sZ., Torres fits., Australia ; 30 fms., white,

sandy bottom (Brazier).

The above is a copy of the original description. I have not
seen the species which is unfigured.

C. ALABASTRUM, ReCVC. PI. 51, fig. 14.

Shell fusiform, alabaster-white, white banded on the subangu-
lated periphery, sparingly marked with chestnut blotches.

Length, 8 mill.

Habitat unknown (Reeve). Mauritius (Martens).

The type formed part of the Taylor collection. It is a very
doubtful species. Yon Martens has figured a shell from Mauritius
to which he applies this name with some doubt.

C. NIVEOMARGINATA, E. A. Smith. PI. 52, fig. 91.

Shell grayish white, with an opaque white band spotted with
chestnut at the top of the whorls, and a narrower one around the
middle of the last whorl, the rest of the surface being marked
with opaque white in an irregularly closely reticulating manner;
whorls smooth, the third and fourth costate ; suture deep;


making the spire appear somewhat turreted ; lip externally
thickened, tubercnlate within, sinuate above. Length, 11 mill.

Described from a single specimen.

C. LISCHKEI, E. A. Smith. PI. 52, fig. 90.

Shell smooth, third and fourth whorls of the spire strongly
costate ; last whorl subangulate on the periphery, contracted
below, with revolving sulci ; outer lip with interior plications
and an external varix ; dirty white, blotched at intervals with
chestnut-brown, the blotches extending from suture to suture.

Length, 1 1 mill. Japan.

Allied to C. alabastrum, Reeve, but has more numerous and
shorter whorls, and differs in coloring.

C. FUSIFORMIS, d'Orb. PI. 52, fig. 88.

Shell fusiform, smooth, with revolving striae below ; spire
elongated, sharp ; lip dentate within. Length, 6 mill.

Jamaica, Martinique.
C. RORIDA, Reeve. PL 52, fig. 89.

Shell transparent white, glassy, encircled round the middle
with a row of milk-white spots ; lip simple. Length, 7 mill.
Lord Hood's Isl. (found on Avicula margaritifera, in coral

sand at the depth of six fms.) (Cuming). Viti Is. (Garrett).
C. tessellata, Dunker, and C. pellucida, Pease, are synonyms ;
neither of them is figured.

C. SOLIDULA, Reeve. PI. 52, figs. 92, 93.

Shell fusiform, thick, shining, with sharp-pointed spire; whorls
encircled by narrow, rather distant grooves, and sometimes the
body-whorl is slightly plicated on the back, just below the suture ;
white, longitudinally streaked, marbled or reticulated with
chestnut, sometimes forming a white band on the periphery ;
edge of columellar lip defined; .outer lip sinuated behind,
thickened and plicate within ; interior of aperture, tip and base
of the shell usually pale violet-tinted. Length, 15 mill.

Cape $. Lucas, Lower California.

C. HIRUNDO, Gaskoin. PI. 52, fig. 94.

Shell solid, smooth, shining ; whitish, freckled with waved
orange-brown lines ; outer lip tubercuiated and sinuous behind.

Length, 16 mill. Habitat unknown.


In the general form and aperture this species looks something
like a Strombina.

C. SUBULATA, Duclos. PI. 52, fig. 96.

Shell with a long, sharp-pointed spire of eleven flattened
whorls, the body-whorl striate and produced below into a long
narrow canal ; aperture long and narrow ; outer lip thickened
and dentate within ; yellowish white. Length, 28 mill.

Habitat unknown.

The above description is made up from the original figures,
one of which I copy. The shell may be a fossil. Sowerby subse-
quently described a very different species under the same specific

C. PLURISULCATA, Reeve. PL 52, fig. 95.

Yellowish brown, spirally grooved throughout, aperture sinu-
ated posteriorly, lip unarmed. Length, 12 mill.

Habitat unknown.

Described from a single, worn and perhaps not adult specimen :
it must be considered a doubtful species.

C. ARATA, Reeve. PL 53, fig. 97.

Shell spirally grooved throughout ; yellowish, variegated with
red-brown spots ; columella excavated ; lip simple, slightly

expanded. Length, 14 mill.

Habitat unknown.

C. OCELLATA, Reeve. PL 53, fig. 98.

Shell finely longitudinally plicate, with revolving grooves at
the base ; whitish, stained and ocellated with orange-brown.

Length, 8 mill.

Habitat unknown.

The eye-like points are said to dip at rather distant intervals
from the sutures. A doubtful species.

C. PELAGIA, Reeve. PL 53, fig. 99.

Shell subulate, the whorls somewhat tubercularly ribbed above,
forming a turreted spire ; aperture small, lips strongly varicose,
notched at the upper part, plicate within : white, marbled with
chestnut, showing a more or less defined white central band, and
white on the sutural tubercles. Length, 8 mill.

Habitat unknown.


C. MONIL1FERA, Sowb. PI. 53, fig. 100.

Shell oblong-acuininated, with well-marked sutures and some-
what rounded whorls ; longitudinally ribbed, crossed and decus-
sated or tuberculated by revolving riblets ; white, chestnut-
spotted on the ribs, leaving a central white band ; aperture rather

narrow, denticulated within. Length, 5 mill.

West Indies.
Reeve's figure of this species is very inaccurate.

C. MANGELTOIDES, Reeve. PL 53, fig. 1.

Shell fusiform, rather solid, longitudinally strongly ribbed;
yellowish, sprinkled with orange-brown spots ; whorls numerous,
flatly convex, sutures impressed, the last whorl produced into a
canal ; aperture small, lip varicose, denticulated within.

Length, 8 mill,

West Indies.

I reproduce Reeve's description and figure : the species has
not been recognized by collectors. I am strongly inclined to
consider it a worn specimen or a variet}^ of C. monilifera, in
which the revolving riblets have disappeared or failed to be

C. FULGIDA, Reeve. PL 53, fig. 2.

Shell rather elongated, transparent white, shining, subangulated
on the periphery ; painted longitudinally with faint waved orange*
brown streaks ; lips slightly denticulated within,

Length, 7-8 mill.

Port Lincoln, Australia (Cuming Coll.).

Noumea, New Caledonia (Brazier).

C. LACTEA, Duclos. PL 53, figs. 3, 4.

Shell smooth, white, striate below; aperture dentate within,
Length, 19 mill.

Indian Ocean, Seychelles Inlands.

Duclos published a figure with name, but no description : his
specimen was possibly denuded of its coloring. The localities
are supplied from Kiener's monograph, although the shell figured
by Kiener is so different (fig. 4) that it may well be another

C. ESSINGTONENSIS, Reeve. PL 53, figs. 5, 6.

Shell smooth, polished, with revolving grooves below; white,


with two narrow chestnut bands, sometimes livid purple without
bands ; exterior margin of aperture varicose, thickened and

smooth within. Length, 13 mill.

N. Australia.
C. EXIMTA, Reeve. PL 53, figs. 7, 8.

Shell smooth, shining, transparent orange, finely reticulated
with brown, encircled by two bands of opaque, snow-white flakes ;
whorls rather flat, the last contracted and grooved at the base,
slightly recurved ; aperture small, lip varicose, slightly notched

at the upper part. Length, 10 mill.

Port Jackson, Australia.

C. bicincta, Angas (fig. 8), is a synonym.

C. EXILIS. Phil.

Shell small, narrowly fusiform; whorls six or seven, flattened,
obsoletely longitudinally plicate ; fulvous, with two white bands,
one of which appears on the spire ; lip slightly inflected and

thick'ened in the middle. Length, 4 mill.

Red Sea near Aden.
Not figured. Unknown to me.

C. PUMILA, D tinker.

Shell small, elongated, attenuated at both extremities, uni-
colored, fuscous; whorls six, longitudinally costate, the costse
covering half the last whorl, which is lirate at the base; columella
sinuous ; lip slightly thickened, plicate or subdentate within.

Length, 4 mill.


L T nfigured. Said to resemble C. exilis, Phil.

C. SERTULARIARUM, d'Orb. PL 53, figs. 9, 10.

Shell elongated, smooth, striate at base, sometimes slightly
longitudinally folded on the body-whorl; yellowish-white, faintly
banded with brown, with sutural markings of brown and white,
alternately ; lip thickened, not dentate. Length, 12 mill.

San Bias, Patagonia.
C. ELATA, Reeve. PL 53, fig. 11.

Shell solid, spire produced, whorls rather narrow, longitudinally
plicately ribbed ; white, longitudinally strigated and waved with
chestnut ; aperture small, columella thinly lipped.

Length, 19 mill. Habitat unknown.

Described from a shell in the Cumingian collection.


C. CUMINGII, Reeve. PL 53, figs. 12-16.

Shell elongated, subcylindrical, recurved at the base, upper
whorls minutely ribbed, all the others covered with close, fine
spiral striae ; outer lip sinuated above, thickened and dentate
within ; purplish, with usually two bands of chestnut dots.

Length, 19 mill.

Island of Capul, Philippines ; Mauritius.

With this species I unite C. lumbricus, Reeve (fig. 13), from
the same locality ; it is described as smooth, but the revolving
striae are represented on the original figure which I have copied ;
the shell is rosy brown, with an obscure reticulated pattern. C.
spicula (fig. 14) and C. clausilia, Duclos (fig. 15), are also

Var. ACUS, Reeve. PI. 53, fig. 16.

Shell longitudinally minutely ribbed towards the apex ; yellow-
ish, irregularly longitudinally streaked with orange-brown ; lip
simple, scarcely denticulated within. Length, 11 mill.

This shell is from the same locality as the preceding, and is,
as Reeve says, of the same general type.

C. FILOSA, Angas. PL 53, fig. It.

Shell elongately fusiform, varying from white to chocolate, the
lighter-colored specimens often with brown maculations at the
suture, the darker-colored ones frequently with whitish sutural
maculations ; whorls eight, slightly convex, covered by fine
revolving striae; outer lip slightly thickened externally and
dentated within. Length, 11 mill.

New South Wales.

Described as a species of J^sopus, Gould ; but the only char-
acter which it seems to possess in common with that genus is
the unimportant one of revolving striae.

C. ATTENUATA, Angas. PL 53, fig. 18.

Shell smooth, shining, moderately solid; whorls eight, very
slightly convex, the last' striate at the base; outer lip simple,
arcuate behind, contracted at the base, with an external brown
varix ; brown, paler beneath the sutures. Length, 9 mill.

Port Jackson, Australia.
C. NYCTEIS, Duclos. PL 53, figs. 19-21.

Whorls flattened, white with angular notches of chestnut, or


uniform white; lip with exterior varix and interior denticula-
tions. Length, 7 mill.

Habitat unknown.

Figured but not described by Duclos, and not recognized by
subsequent students. C. Belizana, Duclos (fig. 21), appears to
be identical.

C. SPIRATELLA, von Martens. PL 54, fig. 22.

Shell small, oblong tut reted, distinctly spirally lirate, yellowish
with nodiform short ribs on the periphery, which are white ; lip
subsimple, canal open, shortly recurved. Length, 4'5 mill.


C. RUBRA, von Martens. (Unfigured.) E. Coast of Patagonia.

Described from an imperfect specimen and referred doubtfully
to Columbella.

Section VI. Anachis, I- 7 . ;>nd A. Adam?.

Shell oval-fusiform, longitudinally strongly ribbed, spire
elevated; last whorl, not narrowed in front; aperture narrow;
columella straight ; outer lip nearly straight, with a posterior
sinus, crenulated within.

C. RUGOSA, Sowb. PI. 54, figs. 23-27.

Shell ovate, tuberculate, plicate or. rudely ribbed, the ribs only
developed on the upper half of the body-whorl, whole surface
with coarse revolving striae ; white, stone-color or light olivaceous,
with large chocolate clouds, especially on the back of the body-
whorl which is sometimes nearly covered with this color.

Length, 18-22 mill.


The ordinary appearance of adults of this species is that shown
by fig. 23 ; sometimes the shell is narrower and less rugose, being
ribbed rather than tuberculate (fig. 24).

The synonyms are C. bicolor, Kiener (fig. 25), and, I think,
C sinuata, Sowerby (figs. 26, 27). The latter has the characters
of C. rugosa, except that the outer lip has a projecting sinus
in the middle; it is a remarkable-looking shell and Sowerby
thinks it " almost generically distinct," yet places it in Anachis.
Judging from the figure, I place it here as a monstrosity of this


C. YOLDINA, Duclos. PI. 54, fig. 48.

Shell with large rounded ribs, forming an obtuse shoulder to
the whorls ; lower part of body-whorl with revolving grooves
and chocolate-color, rest of surface whitish, with a violet band,

visible on the spire. Length, 12 mill.

Habitat unknown.

Figured but not described, and not since identified; it is
possibly an extreme variety of the last species.

C. COSTELLATA, Sowb. PI. 54, figs. 28-31.

Shell narrowly longitudinally ribbed, sometimes slightly tubcr-
culate on the shoulder of the body-whorl ; yellowish brown closely
reticulated with chestnut or chocolate, forming an irregular
darker band above the periphery, and a broader one below it ;
aperture bluish, and sometimes reticulated within ; outer lip
slightly dentate, sinuous behind. Length, 16-20 mill.

Mazatlan; Panama; Guatemala (f); Payta, Peru.

Nearly intermediate in its characters between C. rugosa, Sowb.,
and C. fluctuata, Sowb. C. valida, Reeve Tfig. 29), from Gua-
temala, is described from a worn specimen of this species. G.
varicosa, Gaskoin (fig. 30), is also a synonym ; its locality, Payta,
Peru, is probably erroneous. I add also C. macrostoma (Anton)
Reeve (fig. 31), erroneously said to inhabit the coast of California.

C. FLUCTUATA, Sowb. PI. 54, figs. 32-35.

Shell wide ovate, with somewhat turreted spire, nodulously
ribbed, ribs sharp, curved on, the body-whorl, or sometimes
obsolete below the shoulder ; white, with close, zigzag chocolate
markings ; epidermis yellowish, translucent, thin ; outer lip
broadly sinuous behind, callously thickened, and minutely

dentate within. Length, 16-21 mill.


The synonyms are C. fluctuosa, Duclos (fig. 33), G. suturalis,
Gray (fig. 34), C. costata, Duclos (fig. 35).

C. CORONATA, Sowb. PI. 54, figs. 36, 3T.

Shell yellowish white, sometimes stained with chestnut, with
zigzag longitudinal dark chestnut or chocolate lines ; urjper part
of whorls coronated, the tubercles sometimes giving rise to short,
distant longitudinal plications. Length, -5 -'75 inch.
