SYNOPSES

Holotypes and lectotypes of 130 species of molluscs from the Pacific Ocean described by
W. H. Pease and now in the British Museum (Natural History) are re-described and figured.
Pease’s descriptions, published in the Proceedings of the Zoological Society of London between
1860 and 1865, lacked illustrations, and, in many instances, dimensions. Termed by Pilsbry
(1917) ‘“‘ Linnaean in brevity ’’, these species have long been a stumbling block in the identifica-
tion of the marine molluscs of the tropical Pacific. The present work is intended to clarify
this situation.

INET RODUCTION

In the Cuming Collection in the British Museum (Natural History) are more than 300
specimens sent to Hugh Cuming (1791-1865) the famous London shell collector by
William Harper Pease (1824-1872), an American resident in the Hawaiian Islands.
Correspondence between Cuming and Pease is not extant, but there are references
to communication between them in the Pease letters to Andrew Garrett! (B. P.
Bishop Museum Mss. Coll.). In 1858, Pease wrote Garrett, “I received one
[letter] at last from Cumming [sic]. He sends me names of over 100 of our shells

. ., and in 1860 he wrote, “. . . I rec’d. the box from Cummings [sic].’” Froma
published note it seems that Pease customarily sent not only specimens but also
descriptions of species “‘ where they apparently were new ”’ to his correspondents
(Pease, 1868b). The descriptions accompanying the new species sent to London
were published between 1860 and 1865 by the Zoological Society of London, of
which Pease was a corresponding member. The types were incorporated into the
Cuming Collection, as Pease pointed out in 1868 to J. E. Gray, then Keeper of
Zoology in the British Museum (Natural History): “.. . [the types] are in the
Cumingian Collection, . . . which I furnished Mr. Cuming myself.’’ (Mss. letter,
Foreign Letters, Vol. II, B.M.(N.H.).)

Andrew Garrett (1823-1887) was an American naturalist who travelled extensively in the Pacific.
His travels were largely financed by the House of Godeffroy for which he made extensive collections.

EeeAr [SOND tGAIY,

The species described by Pease and the specimens which he sent to Cuming came
from several island groups in the Pacific including the Hawaiian Islands. The
majority of these were collected by Pease himself on several of the islands in the
Hawaiian chain, primarily the islands of Oahu and Kauai. Pease was a resident of
Kauai from 1850 until 1856 or 1857, and then moved to Oahu. The molluscs from
other Pacific Islands (Tahiti, Jarvis Island, the Gilbert Islands, etc.) were collected
by Andrew Garrett on his travels in the Pacific and sent to Pease for description
(Pease letters to Garrett, B. P. Bishop Museum Mss. Coll.). Pease did not leave the
Hawaiian Islands between his arrival in Honolulu in 1850 and his death there in 1872.

This study is concerned with the marine molluscs described by Pease in seven
papers published between 1860 and 1865. The only marine species described in
these papers which were not apparently included in the Cuming Collection were the
majority of the opisthobranchs described in 1860 and 1861. Examples of these,
accompanied by coloured illustrations by Garrett were deposited in the Museum de
Godeffroy in 1874 (Bergh, 1889). Bergh (loc. cit.) published illustrations of some of
the species, and indicated that he had made anatomical studies of several. The
specimens were destroyed during the bombing of Hamburg in the 1939-45 War.
Of the species described by Pease from the Cuming Collection the types of 30 proso-
branchs, one pulmonate, and two lamellibranchs have not been found.

As a part of the Cuming Collection the Pease types have been variously treated
in the century since their original description. Twenty-six of the type specimens
were illustrated in the works of the English iconographers Lovell Reeve (1814-1865)
and G. B. Sowerby (1812-1884). One of Sowerby’s illustrations actually antedates
the publication of Pease’s descriptions, and the authorship of this species, Evato
sandwicensts, is properly ascribed to Sowerby (1859). A number of the types were
compared with specimens collected from other regions of the Indo-Pacific by J. C.
Melvill and R. Standen, E. A. Smith, A. H. Cooke, J. R. le B. Tomlin, T. Iredale,
and others.

Methods. Since the purpose of this work is merely to figure and re-describe the
marine molluscan species described by Pease, neither a systematic arrangement
of species nor a taxonomic treatment is attempted here. The sequence of species
is that of Pease who followed no particular style in presenting his descriptions.
Although synonymies have not been included, an annotated list of references is ap-
pended for each species. While these lists are inevitably incomplete, the range in
geographical area and in time that they present should make them adequately
representative for many purposes. Synonymies indicated by the various authors
have been included in the list of references.

The specimens are listed under their British Museum (Natural History) [abbrevia-
ted as B.M.(N.H.)] registration numbers. The term holotype is applied only to the
types of those species represented by a single specimen in the Collection. Lectotypes
have been selected from the cotype series, and where it seemed appropriate, the
specimens selected were those previously illustrated by Reeve or Sowerby. Dimen-
sions are given in millimeters. The original description is quoted for each species
and comments have been added to clarify some of the rather broad descriptions given

PEASE S-MARINE MOLLUSCS IN. THE CUMING COLLECTION 5

by Pease. Descriptive terminology is that found in Moore (1960). Notes on the
present knowledge of the occurrence of the species have also been included. All
recent collection data are referable to the islands of Kauai and Oahu in the Hawaiian
Islands. The.abbreviation H./. indicates Hawaiian Islands. When types have not
been found the species concerned are listed at the end of the paper.

The photographs of the types were made by the staff photographers of the B.M.
(N.H.) and by the author, with the exception of the photographs of Alcyna rubra
and Collonia variabilis which were taken by Robert Robertson of the Academy of
Natural Sciences of Philadelphia. The drawings were made by the author with the
aid of a camera lucida.

History) for their kind permission to examine this collection and for providing
facilities for study in the Mollusca section of the Zoology Department.

PEASE’S DESCRIPTION: “ Shell ovate, thin, fragile, white, with or without one

or two sets of two or three fine transverse black lines on body whorl, transversely
finely grooved ; interstices punctured ; spire obtuse ; apex acute ; whorls four ;
aperture oval, dilated at the base ; slight fold at the base of the columella (not
imperforate, umbilicated).”’

LECTOTYPE (here selected) : B.M.(N.H.) Reg. No. 1961456. Length, 11 mm. ;
diameter, 7mm. Paralectotype (1961457) : length, 11 mm. ; diameter, 7 mm.

REMARKS: The entire shell is marked by regularly spaced spiral grooves which
are closely punctate, the punctations showing through the transparent shell in the
aperture like links of a chain. The columella is straight and vertical, lacking folds
and plaits, and ending abruptly on the outer lip. The protoconch is small, convex,
and smooth.

6 VANE DSOIN ECAC;

Beachworn specimens of this species although resembling ‘Bullina lauta Pease
below are distinguished by their thin, almost transparent shells, distinctly punctate
grooves, and their straight columella. |

Both living and beached specimens are rare in the Hawaiian Islands. A single
living animal was recently collected at Ala Moana Beach Park, Oahu [H.I.], where
it was found partially buried in a shallow, sandy depression at the low tide level.

PEASE’S DESCRIPTION : “ Shell small, cylindrical, shining, white, finely striated
transversely ; spire elevated ; whorls four; aperture contracted posteriorly,
dilated anteriorly ; slight fold on columella.”’

LECTOTYPE (here selected) : B.M.(N.H.) Reg. No. 1962751. Length, 5 mm. ;
diameter, 2mm. Paralectotype (1962752) : length, 5 mm. ; diameter, 2 mm.

REMARKS: The type set consists of five somewhat beachworn specimens, two of
which lack protoconchs, a third with an elevated, convexly conic spire, and two
specimens with distinctly projecting protoconchs. The specimen with the elevated,
convexly conic protoconch has been selected as the lectotype on the basis of Pease’s
description of “. . . spire elevated ; whorls four. . .’’, and the lack of mention of
a projecting protoconch. Pilsbry (1917) pointed out there were two similar but
distinct species occurring in the Hawaiian Islands and suggested that the typical
T. sandwicensis was the form with the low spire, naming the form with the projecting
spire T. honoluiuensis. The two specimens in the set with the projecting protoconch
have, therefore, been segregated as T. honoluluensts.

Although there are no recent records of live collections of 7. sandwicensis from the
Hawaiian Islands, specimens have occasionally been recorded from beach drift.

PEASE’S DESCRIPTION : ‘“‘ Shell suboval, thin, fragile, slightly narrowed posterior-
ly, smooth, with the exception of the longitudinal lines of growth ; outer lip slightly
produced posteriorly, and rounded ; aperture narrowed posteriorly, and slightly
dilated at the base ; columella with a light fold, white and shining.”’

The description of the animal which follows the description of the shell was ‘subse-
quently noted by Pease (1861b : 432) to be that of H. galba, and the description of the
animal of H. crocata was inserted following the shell description of H. galba (Pease
loc. cit.).

S fe Cephalic disk square, oblong, in advance of the shell, slightly notched
at the centre of the front side, at the posterior side provided with a pair of flat,
rather broad, recumbent lobes, which are rounded at their extremities ; lateral
lobes reflected on the sides of the shell two-thirds of its length ; foot extending be-
yond the shell posteriorly, and rounded at its termination. Colour cinerous ; pel-
lucid.”’

LECTOTYPE (here selected) : B.M.(N.H.) Reg. No. 1961199. Length, 12 mm. ;
diameter, 7°5 mm. Two paralectotypes (1961200) : length, 13 mm. ; diameter,
7mm. ; length, 12 mm. ; diameter, 8 mm.

REMARKS : The shell is involute with the protoconch concealed and the apex
rounded. The columella curves, protruding beyond the base. The columellar
callus is smooth, ending on the lower portion of the outer lip.

The types of H. crocata are chalky white, a condition frequently encountered in
tectibranch shells collected from beach drift. A discussion of characters distinguish-
ing this species from the following species, H. galba, appears in the ‘“‘ Remarks ”’
under HZ. galba.

covering about one-half of its length, and nearly meeting at the back ; posterior
lobe covering the spire ; foot subquadrate, extending a short distance beyond the
shell posteriorly ; eyes central, immersed, black, surrounded by white areolae ;
colour of the animal varying from grey to greyish-yellow, and in some nearly to black,
being closely mottled and freckled with olive or dusky.”

diameter, 10 mm. Two paralectotypes (1961195) : length, 17 mm. ; diameter,
igemmne--length, 17 mm. ;° diameter, 10 mm.

REMARKS : To Pease’s description should be added the following : shell involute,
protoconch largely concealed, apex shouldered, columella curving but not protruding
beyond the base of the shell, callus thick, and the shell covered with fine dark brown
spiral striations on a yellow ground. Pease did not mention these striations which
immediately distinguish the shells of this species in the type lot from those of H.
crocata.

In addition to the brown striations, the shells of H. galba differ from those of H.
crocata in that they are larger (17 mm. in length) compared to the 7-13 mm. length
of the types of H. crocata ; the apex is shouldered rather than rounded as in H. cro-
cata ; and the columella ends on the posterior extremity.

Although beached shells comparable with the types of H. crocata are of common
occurrence in drift from the shores of both the islands of Oahu and Kauai [H.I.],
none corresponding with the types of H. galba have recently been identified. The
positive identification of living specimens of H. galba must await further study of
the various species of Haminea which occur in Hawaiian waters.

surface finely cancellated ; apex slightly umbilicated or perforated ; aperture
narrow, contracted posteriorly ; slight fold at base of columella.”’

LECTOTYPE (here selected) : B.M.(N.H.) Reg. No. 1962754. Length, 3-5 mm. ;

1 PAE Si OINN ECAR,

REMARKS : The finely cancellated surface described by Pease is produced on the
entire surface of the shell by fine spiral grooves which are crossed by equally fine
longitudinal grooves. The aperture is long, narrowed in the middle where the outer
lip is reflected inward, and flaring at the base ; the outer lip parallels the parietal
wall except at the expanded basal third of the shell. The columella is straight,
reflected briefly, and joins the outer lip in an even curve.

Specimens are commonly collected in beach drift in the Hawaiian Islands.

REMARKS: The shell is involute ; the adapical umbilicus is narrow but not

perforate as described by Pease. The body whorl is evenly rounded anteriorly and
posteriorly. Expanding anteriorly and posteriorly, the aperture is narrow and
semilunar. The outer lip ascends above the apex and then sweeps in a smooth
era to the anterior extremity. The columella curves forward forming a narrow
shelf.
_ Living specimens are occasionally collected on the sandy substrate beneath rubble
in the shallow waters of sheltered bays in the Hawaiian Islands. The animal is
white, with three bands of red spots across the mid-dorsal region. Specimens are
frequent in beach drift.

PEASE’S DESCRIPTION : “‘ Shell cylindrically ovate, elongate, narrowed posterior-
ly, pellucid, fragile, white ; outer lip produced and twisted posteriorly ; apex
umbilicated, and umbilicus striated or grooved, finely striated transversely, trans-
verse raised lines at both ends ; columella with a fold at the base.”

LECTOTYPE (here selected) : B.M.(N.H.) Reg. No. 1961197. Length, 13 mm. ;
diameter, 5:5 mm. Two paralectotypes (1961199) : length, 13 mm. ; diameter,
6mm. ; length, 12-5 mm. ; diameter, 5 mm.

REMARKS :_ The apex is narrow and deeply impressed around the axis, about the
base of which there is a shallow concavity. The ascending axis is broad, terminating
in a posteriorly projecting point. The sculpture consists of approximately 14 spiral
grooves which are irregularly spaced anteriorly, and 10 posteriorly.

Although the Sowerby (1870) figures, which were of the types, suggest the posteri-

orly projecting point, neither the Martens and Langkavel (1871) nor the Kobelt
(1896) illustrations of the species show the point. Pilsbry (1917) remarked that
Pease did not note the projection in the original description.
_ The Sowerby (1870) figures exaggerate the narrowness of the posterior whorl.
Comparison of the types with the illustrations suggests that the artist included a
portion of the whorl in the shadow of the lip, thus emphasizing the narrow posterior
whorl. Pilsbry (1917) described a new species, A. cornuta, from the Hawatian
Islands, solely on the basis of a wider posterior whorl ; this species should be com-
pared with Pease’s A. debilts.

PEASE’S DESCRIPTION: “ Shell thin, horny, subpyriform, convolute (finely
striated longitudinally), covered with a membranaceous epidermis ; spire none ;
aperture wide, dilated at the base and contracted posteriorly ; the lips thin and
entire, meeting at about one-half the length of the shell and folding closely one over
the other, posteriorly produced in the form of a tube, leaving a circular aperture ;
colour yellowish.”’

“Animal. Mantle not exposed ; cephalic disk quadrate, slightly in advance of the
shell ; tentacular lobes four, produced from the corners of cephalic disk, round, short
and bluntly rounded at their extremities, anterior pair slightly longer ; foot small,
not extending posteriorly beyond the aperture, and not reaching in front the anterior
side of the cephalic disc, of an oblong triangular shape, widest in front ; eyes minute
at inner base of posterior tentacles ; anal opening at posterior aperture ; colour
white.

Mus. Cuming.

This anomalous animal was found on sea-weed dredged from a salt-water pond. It
remained alive several days in a glass jar ; it was very timid and slow in its move-
ments. The animal would occasionally protrude slightly from the posterior aper-
tire:

HoLoTyPe: Shell fragments only. B.M.(N.H.) Reg. No. 1962753.

REMARKS : Pease erected a new genus, Volvatella (Pease, 1860a : 20), to include
the species he was describing. Three additional species were later described, two
by Pease in 1868d, and one by G. and H. Nevill from Ceylon in 1869. Evans (1950)
proposed a revision of the genus because of several discrepancies in Pease’s species
descriptions. While retaining V. fragilis as the type species of Volvatella, Evans
proposed the genus Avthessa to include the Nevill species and a newly described
species from Zanzibar (Evans, 1950). No collections of specimens which can be
identified as V. fragilis have been recorded in the Hawaiian Islands since Pease’s
original description (Edmondson, 1933 ; 1946). A species, A. evansi, recently
described as congeneric with the two species in the genus Avthessa has recently been

... has not been ob-

described by Kay (1961) ; although the shell of this species is similar to that described
by Pease (1860a), the animal is orange-yellow and following Evans’ distinction
between Avthessa and Volvatella, the species was included in the genus Arthessa.

PEASE’S DESCRIPTION : “‘ Elongate pyriform shape, rounded posteriorly, rugose,
and ornamented with small filaments. Back convexly rounded. Mantle lobes small,
rounded and closely enveloping the body, the right overlapping the left, leaving two
small orifices ; a groove extends from the mantle lobes along the back and right
side of head to the mouth. Dorsal tentacles grooved laterally and slightly dilating
outwards. Oral tentacles longer than the dorsal, and curved forwards, grooved and
much dilated. Eyes small, black, distinct, sessile in front laterally to dorsal tenta-
cles. Mouth with a bilobed veil. Foot smooth ; shape same as body. Colour
varies ; usually of a dark olive-green with sap-green margins, and varied with whitish
and dusky. Filaments pale. Foot pale greenish-slate, dotted with dusky brown
and white.

The eggs are deposited under stones, coiled from right to left.

HoLoTyPE: B.M.(N.H.) Reg. No. 1964376. Length, 8 mm. ; diameter, 3 mm.

REMARKS: The shell of this species has not been figured because it is of little
use in the identification of species of Dolabrifera. The shell is, however, that of
Dolabrifera, and undoubtedly that of the circumtropical species D. dolabrifera. The
species is common under rocks near the shoreline in the Hawaiian Islands.

“Remarks: The type lot consists of two specimens, both of which have four
somewhat indistinct whorls. The aperture is irregularly ovate. The columella is
straight, with two small folds mid-way.

The illustrations in Martens and Langkavel (1871), Tryon (1883), and Kobelt
(1896) are misleading in that the sculpture is indicated as being evenly spaced and
the granules the same size. The Martens and Langkavel (1871) illustration does not

show the yellow granules, and the Kobelt (1896) illustration indicates golden bands
rather than knobs.

In the Hawaiian Islands, living specimens are occasionally collected under loose
rocks in tidepools and along the shoreline. Beachworn specimens, usually very
faded, are frequent in drift.

REMARKS : The two specimens in the type lot are beachworn, mottled white and
brown and clouded with water marks. The shell is fusiform with seven distinct
whorls. The sculpture consists of axial ribs crossed by sharp spiral striae between
which are finer interstitital striae ; the primary striae form nodulous edges on the
ribs. The thin outer lip bears four or five ridges internally. The columella is arched
and covered by a wrinkled callus which is widely reflected over the body whorl.

REMARKS : The shellis white. There are four whorls plus the protoconch. The
spire is twice the length of the aperture plus the canal. The base very gradually
contracts, and the canal is moderately long and broadly open. The sculpture is
strong, the axials more prominent than the spirals. There are 14 axials and 6-7
spirals per whorl. The fasciole has four granular threads. The protoconch consists
ar ie whorls ; the posterior whorl has slight cancellations ; the others are glossy
yellow.

5. bifasciata may be distinguished from B. lutea by its smaller size (5 mm. compared
to 9 mm. in length), rounded whorls, and prominent axials.

PEASE’S DESCRIPTION : “ Shell fusiformly elongate, ornamented with transverse
granular ribs, and fine longitudinal raised striae ; whorls slightly convex ; aperture
elongate-oval ; canal short. Colour dark brown.’’

LECTOTYPE (here selected) : B.M.(N.H.) Reg. No. 1962763. Length, 7 mm. ;
diameter, 2-5 mm.; aperture plus canal, 2-5 mm. Three paralectotypes (1962764) :
length, 6mm. ; diameter, 2mm. ; aperture plus canal, 3-5 mm. ; length, 6:5 mm. ;
diameter, 2°5 mm. ; aperture plus canal, 2-5 mm.; length, 6 mm. ; diameter,
2mm. ;. aperture, plus canal, 2°5:mm.

REMARKS : The lectotype which was selected from the type lot of four specimens
was chosen on the basis of Pease’s description of the shell as “‘ dark brown’. That
the species varies in colour is indicated by the variation shown in the other three
specimens which are variously mottled brown and white. The sculpture is also
variable, worn specimens, such as the lectotype, having weak axials and spiral gran-
ules, whereas live-collected specimens have distinctly bead-like axials and spirals.

The shell is fusiformly elongate, solid, brown, becoming cream at the base. The
post-nuclear whorls are convex, sculptured by spiral cords of granules : three, four,
and ten on the body whorls. The whorls are gently shouldered, with the posterior
row of granules at the suture more prominent than the others, and usually of a lighter
shade. The sinus is of the daphnellid type. The base is straight, as is the columella.
The outer lip has a deep sinus ; the inner teeth are only slightly developed. A
portion of the protoconch only remains on the lectotype ; in the paralectotypes the
protoconch consists of two convex whorls cancellated with brown.

Living specimens are occasionally collected under loose rocks in tide-pools and
from shallow bays in the Hawaiian Islands. Beachworn specimens are frequent in
drift.

REMARKS : The shell is small, shining, white. The post-nuclear whorls are
elongate, slightly convex, gently shouldered, and marked by strong axial ribs tuber-
culated with spiral cords. The intersection of the spiral cords and the axial ribs
forms very strong tubercles, while the spaces enclosed between them appear as well
impressed, rectangular pits. There are nine axial ribs on the last whorl, eight on the
three preceding. The spiral cords number seven on the last whorl, five on the penul-

timate, four, and finally three. The fasciole has two spiral threads. The sutures are
gently sloping and the whorls are consequently shouldered. The outer lip is thin,
banded by the external sculpture, and flaring. The columella is straight ; the sinus
is Shallow. The protoconch is eroded on the holotype.

PEASE’S DESCRIPTION : “ Shell small, ovate, longitudinally ribbed, row of gran-
ules bordering suture, transversely finely striated. Colour dark brown ; whorls
encircled by a single narrow light-brown belt ; columella five-plaited ; aperture
purplish white.”

EIOLOTYPE :* B.M.(N.H.) Reg. No. 1962772. Length; 7 mm..;. diameter, 3°5 mm.

REMARKS : The shell is yellow-brown, with three post-nuclear whorls plus an
eroded protoconch. The granules bordering the suture form a narrow, light-brown
belt. There are four columellar plaits, rather than five.

Both the Martens and Langkavel (1871) and Sowerby (1874) illustrations are
misleading, in that the former indicates a darker colour, blunt posterior, and does
not show the columellar rugosity ; the latter indicates no sculptural detail and a
purple-brown colour.

In the Hawaiian Islands beached specimens are of frequent occurrence in drift on
the islands of Oahu and Kauat.

diameter, 1-5 mm. Paralectotype (1962779) : length, 2 mm. ; diameter, I-5 mm.

REMARKS: The shell is convolute and semitranslucent. The spire is short and
broadly conic. The whorls are not separated by distinct sutures. The left margin
of the shell is gently rounded, the aperture is narrow, and the outer lip, which has
minute teeth on the inner edge, is bent inwards in the middle. The parietal region is
covered by a thin callus ; the columella has two oblique folds of equal size.

In the Hawaiian Islands the species is very common in the shallow waters of
sheltered bays where it lives on algal-encrusted rocks and pieces of dead coral. It
is also commonly found in beach drift.

REMARKS: The shell is fusiform, solid, with indistinct sutures. On the last
whorl the sculpture consists of axial ribs which are interlaced with spiral bands, the
ribs and bands producing a ladder-like effect. The adapical whorls are similarly
sculptured but have in addition a row of obsolete granules bordering each suture.
The neck is sculptured with approximately eight spiral bands separated by longitudi-
nally striated depressions. The columella is straight, with a thin callus. The abapi-
cal portion of the outer lip curves inward, and there are obsolete lirations internally.
The lectotype is white with yellow splashes on the last whorl, but the species varies
in colour as is indicated by the other three specimens in the type lot in which the
last whorl ranges from white to dark brown.

In the Hawaiian Islands the species is occasionally collected on the under-surfaces
of small rocks in tidepools and shallow bays. It is commonly found in beach drift.

REMARKS: There are four whorls plus the protoconch. The protoconch is
small, with a depressed nucleus followed by a flattened whorl with a convex spiral
keel. The aperture is approximately one-third the length of the spire. The sculp-
ture consists of regularly spaced axial ribs, 10-12 on the earlier whorls, and about
15 on the last whorl which are obsolete or lacking at the sutures but which form
nodules below the sutures. The spiral sculpture consists of evenly spaced threads
overriding the axial ribs, forming the only sculpture in the angled sutures and on
the base. There is a narrow band of callus on the columella. The outer lip is
heavy.

The Martens and Langkavel (1871) figure does not indicate the spiral sculpture on
the shell.

Specimens are frequent in drift in the Hawaiian Islands.

REMARKS : The shell is subulate, white with a few faint light brown splashes.
The protoconch consists of one and one-half whorls which are white, bulbous, and
slightly oblique. The four spire whorls are convex, bulging to the right more than
to the left. The sculpture consists of spiral rows of small bead-like granules with
faint axial striae between. The spirals are not of equal strength, but a weaker or
smaller row may lie between two stronger rows. In the adapical whorls the beads
are worn, producing a cancellate effect. The outer lip is thin. The columella is
sinuous with a thin callus. The neck is striated with granules similar to those on
the last whorl.

In the Hawaiian Islands specimens are occasionally found in tidepools, where
empty shells are frequently inhabited by hermit crabs.

REMARKS: The shell is small and milk white. The protoconch consists of one
and one-half well rounded, smooth whorls. The spire whorls are marked by strong
spiral keels, between which are weaker keels, often with the middle intercalary keel
stronger than the others. The base projects as a moderate canal, with the neck
striated. There is a moderately large umbilicus. The aperture is oblique. The
outer lip is fluted by the external sculpture which is also apparent through the sub-
stance of the shell.

Of the set of three beachworn specimens from which the lectotype was selected,
the lectotype is in the best condition.

Beachworn specimens are common in drift in the Hawaiian Islands.

close obliquely transverse impressed striae on the basal half ; suture impressed, and
margined below with a fine spiral impressed line ; aperture about one-half the length
of the shell, oblong-oval, slightly effuse above ; outer lip simple ; columella smooth,
slightly arched ; whitish horn-colour ; last whorl ornamented with one or two rows
of oblong brown spots and an opake white spot, intermediate rows extending to
and encircling the lower part of the upper whorls near the suture.”

LECTOTYPE (here selected) : B.M.(N.H.) Reg. No. 1962794. Length, 6-5 mm. ;

length, 7 mm. ;\ diameter, 3 mim. ; length, 7.1mm. ;.diameter,3 mime.

REMARKS : The shell is slender, high-spired, smooth, horn-coloured but varie-
gated with brown and white. The protoconch consists of two and one-half white,
smooth, convex whorls. The spire whorls are convex, with indistinct sutures, and
swollen just below the summit. The two abapical whorls are marked by an indis-
tinct line below the summit. The base is short, marked with spiral striations. The
columella is smooth with a thin callus reflected over the basal striations. The aper-
ture is moderately large, with the adapical angle reflected upward as a gentle channel.
The outer lip is thin.

The shell is marked by two oblique bands of rectangular brown marks on the last
whorl, the lower band ending below the reflexion of the outer lip, the upper above the
lip. Between them is a row of white spots. There is a similar row of brown spots
at the base of the two adapical whorls and white on the base.

The set from which the lectotype was selected consists of three beachworn speci-
mens. The specimen selected as the lectotype conforms most closely to Pease’s
description of the colour pattern. The other two specimens include an almost pure
white specimen marked only by some milk-white dashes across the last whorl and a
specimen with faint brown marks and white dashes. Although Pease (1868c) later
remarked that the ip was“. . . finely denticulated within. . .’’, denticulations are
present only in the lectotype.

Specimens are found only rarely in drift in the Hawaiian Islands.

REMARKS : The shell is elevated-conical, with bulbous spire whorls. The proto-
conch consists of one and one-half white, shining, oblique whorls. There are six spire
whorls which are sculptured by narrow oblique lirae. The sutures are strongly con-
stricted. The aperture is circular, the outer lip thin. The collumellar lip is thicken-
ed, curved, and reflected. The parietal region is covered by a moderately thick
callus which is not continuous so that the peristome is not complete.

Specimens are collected only rarely on reef flats in the Hawaiian Islands.

mm. ; diameter, 4 mm. ; aperture length, 2:5 mm.

REMARKS : The shell is elevated-conical. The protoconch is broken. The spire
whorls are well-rounded, obliquely crossed by wide, lamellose axial ribs. There are
seven or eight ribs on the adapical whorls, nine on the last whorl. The ribs form
continuous lines on the spire, and are marked by conspicuous hooks near the summit
of the whorls. The spaces between the ribs are marked by fine cancellations, which
produce a checker-board effect. The sutures are very strongly constricted. The
aperture is oval, the outer lip bordered by a rib with a hook at the juncture with the
body whorl, the columellar lip thickened as the outer lip and strongly curved. The
parietal region is covered by a thick callus which renders the peristome complete.

The lectotype is white with a faint brown band running across the centre of each
whorl, the band almost faint enough to be a shadow. The second specimen in the
type set is smaller than. the lectotype and also lacks the protoconch. The brown
bands are more conspicuous on this specimen than on the lectotype.

Beachworn specimens are common in drift in the Hawaiian Islands.

REMARKS: The shell is deeply umbilicate, elongate, thin, and semi-transparent ;
brown, mottled with white. The surface is glossy, marked obscurely by longitudinal
lines and fine spiral striae. The columella is straight, reinforced by a wide reflected
callus which expands and spreads over the parietal wall. The outer lip barely pro-
jects above the spire and follows the parietal wall closely. The base is rounded.

The animals appear in large numbers on the dead reef-platform of Ala Moana Reef,
Oahu, in the Hawaiian Islands, during the months of January and February. The
animals swarm up through the porous coral and gravel during full moon at low tide,
and disappear into the substrate as the tide turns. The animal coloration varies
from bright orange to dull brown.

REMARKS: The shell is cyrtoconoid, red-brown with yellow stripes. The proto-
conch is eroded. The sculpture on each of the spire whorls consists of an adapical
dark red-brown granular spiral, a small undulated yellow thread, and an abapical
spiral of large yellow granules. The base is rounded with three dark spirals on
a yellow ground. Between the basal spirals are three fine intercalary spirals of
beaded threads. The aperture is round ; the outer lip thin and expanded. The
sutural sulcus is circular and nearly closed by an extension of the outer lip.

Specimens are occasionally found associated with sponges in tide pools, and beach-
worn specimens are very common in drift in the Hawaiian Islands.

I. congulifera differs from 7. alternata Pease 1861 (p. 54) in that a row of brown
granules alternates with a row of yellow. In T. alternata there are two yellow rows
bordering a brown row on each whorl.

PEASE’S DESCRIPTION: “Shell turreted ; whorls composed of three regular-
sized rows of granules, the middle one of dark reddish brown, the remaining two of a
waxy-yellow colour ; base longitudinally striated ; canal closed, tubular.”

LECTOTYPE (here selected) : B.M.(N.H.) Reg. No. 1962816. Length, 7 mm. ;
diameter, 2-5 mm. Two paralectotypes (1962817) : length, 6 mm. ; diameter, 2
min.; length! 51mm. ; diameter, 1-5 mm.

REMARKS: The shell is turriculate, brown with white stripes. The protoconch
is eroded. The spire whorls are moderately rounded, ornamented on the first three—
four adapical whorls by two rows of beaded granules. About the fifth turn the
whorls become distinct, and there are three rows of granules on the following whorls.
Of the three rows, the adapical is light brown and consists of oblong beads, a distinct
concavity separating it from the middle row which consists of much larger white
granules which touch one another. The abapical row consists of oblong horn-coloured
granules which are shelved adapically. The suture is deep with obsolete granular
swellings continuous in it. The base is rounded with two spiral keels, one at the
periphery just below the last granular spiral which meets the outer lip, the other
ending at the top of the columella. The columella is twisted, with a heavy callus in
the parietal region. The outer lip is thin, the external sculpture showing through.
The canal is curved posteriorly.

Features distinguishing T. alternata and T. congulifera have been discussed under T.
cingulifera.

Beachworn specimens are common in drift in the Hawaiian Islands.

length, 9 mm. ; diameter, 1-5 mm. ; length, 12 mm. ; diameter, 3 mm.

REMARKS: The shell is turriculate, ight chestnut-brown. The protoconch is
eroded. The spire whorls are convex, marked by strong keeled spiral cords, the
alternate cords smaller than the two bordering cords. Of the two bordering cords,
the adapical is the larger. All three cords are equally spaced, the spaces between
almost smooth or marked with very faint striae. The periphery of the last whorl is
marked by a prominent cord, and the base by a single cord which terminates above
the columella. The columella is twisted, with a callus covering the apertural surface.
The outer lip is thin, with the external sculpture visible through it. It is notched at
the junction with the last whorl.

In the Hawaiian Islands specimens are frequently collected clinging to the under-
surface of loose rocks on reef flats and in shallow bays. Live-collected specimens are
darker brown than the beachworn types, and are frequently encrusted with calcareous
algae and serpulids.

REMARKS : The shell is small, globose, and white. The protoconch consists of
one and one-half white, somewhat worn whorls. The sculpture of the other two
whorls consists of oblique lirae cancellated with spiral striations. The whorls are
distinct, slightly shouldered at the sutures. The umbilicus is moderately deep, with
ridges and grooves, the latter marked by faint cross lirae.

Smith (1908) noted that the species differs from V. acuta Récluz by the presence
of the oblique lirae and generally oblique form.

Living specimens are occasionally found on the undersurfaces of small rocks in
tidepools in the Hawaiian Islands.

other whorls are convex, and marked by granular spiral cords. There are three
worn cords on the adapical whorl, four on the next, and five on the last whorl.
Faint axial riblets run between the spiral cords which are well separated from one
another on all the whorls. The periphery of the last whorl is somewhat angular and
marked by a spiral granular cord. The base is flattened, with three—four obsoletely
granular cords between the periphery and the smooth umbilical region. The aper-
ture is subcircular, the outer lip thickened, and there are three or four teeth internally,
a wide groove, and a tooth at the termination of the columella. The columella is
straight, white, and shining. The umbilicus is narrow and very deep.

In the Hawaiian Islands specimens are frequently collected on the undersides of
rocks in shallow bays and in tidepools. Beachworn specimens are frequent in drift.

HoLoTyPeE : B.M.(N.H.) Reg. No. 1962823. Length, 3-5 mm. ; diameter, 4mm.

REMARKS: The shell is small, sturdy, pearly white with an iridescent aperture.
The protoconch consists of one and one-half white, smooth, whorls which are some-
what elevated above the next whorl. The whorls are marked by spiral cords and
axial riblets forming tubercles at their junctions with the spiral cords. The spiral
cords project outward, giving the whorls a sharp, angular appearance. Of these
cords, there are two, three, and four on the succeeding whorls from the apex. The

spiral cords are separated on all the whorls by shallow spaces about equal to the
cords in width. The sutures are slightly constricted. The periphery of the last

_whorl is marked by the usual spiral cord but it is smaller than the preceding cord.
The base is short, rounded, marked by four obsoletely granular cords. The umbilical
area is smooth and there is no umbilicus. The aperture is subcircular, with the
posterior angle obtuse and the outer lip very slightly thickened and flaring outward ;
the lip is faintly denticulated. The columella is straight and terminates in a pro-
jecting tooth.

REMARKS: The shell is ovate-conical, of four convex post-nuclear whorls
separated by constricted sutures ; the protoconch is eroded. The outer lip is smooth,
slightly thickened internally, and the columellar tooth projects into the aperture.
There is a shallow, elongate pseudumbilicus, which is striated by three to five fine
grooves. The shell is pink, ocellated with small white spots ; the second and last
whorls are banded by a white ribbon with flammules of light brown ; the apex is
white.

The type lot originally consisted of fifteen specimens, three of which were pointed
out by Robertson (personal communication) to be examples of Collonia variabilis
Pease. The eleven paralectotypes show considerable variation in colour, varying

PEASE’S MARINE MOLLUSCS IN THE CUMING COLLECTION 63

from solid pink to white encircled by narrow bands of dark red. The umbilical area
is variously developed, ranging from a shallow trough to a solid base ; the base is
smooth in some specimens but engraved with fine spirals in others.

The same variability has been noted within live-collected colonies of this species
in the Hawaiian Islands.

The specific epithet vubra is a misnomer ; while beachworn specimens are red or
deep pink, specimens collected alive are olivaceous, assuming a red colour only after
they have been out of water for some time. The species is common in beach drift
- from the shores of Oahu and Kauai [H.I.], and living animals occur in an encrusting
red alga on small rocks in tidepools and shallow bays.

mm.

REMARKS: The holotype conforms to Pease’s description except in colour ; it is
white. Pilsbry (1917) has remarked on various colour differences among specimens
of A. subangulata from the Pease collection at the Museum of Comparative Zoology,
Harvard University.

The shell is small, conoidal, and with angular whorls ; the post-nuclear whorls are
marked by fine spiral threads ; the sutures are only faintly constricted. The aper-
ture is subcircular, the outer lip thickened with a swelling externally below the suture.
The pseudumbilicus is triangular, with ridges and grooves leading from it. The
columellar tooth projects posteriorly into the aperture. The protoconch is smooth,
_ white, and flattened apically.

In the Hawaiian Islands beachworn specimens are occasionally collected in drift
_ from the shores of Oahu and Kauai ; they range in colour from deep rose striated with
_ red to pale pink.

2mm. ; length, 3-5.mm.; diameter, 2mm. ; length, 2-5 mm. ; diameter, I mm.

REMARKS: The shell is small, ovate, polished, white with a light brown band on
the apical third of the penultimate whorl. The protoconch consists of three white,
polished whorls which are considerably more slender than the spire whorls and tilted
to one side. There are five spire whorls which are convex and separated by con-
stricted sutures. The base is relatively long and rounded. The aperture is oval,
and the posterior angle is acute but wide. The outer lip is thin and sinuous ; the
inner lip is reflected over the base of the shell. There is a thin callus over the parietal
region.

Of the four specimens-comprising the set, the specimen selected as the lectotype
was the only one showing the brown coloration and the only one in perfect condition ;
the others lack the protoconch or have broken lips.

In the Hawaiian Islands living animals are not infrequently collected on Holothuria
atra on the islands of Kauai and Oahu.

PEASE’s DESCRIPTION: “Shell subulate, light, thin, white, longitudinally
ribbed and decussately spirally striated ; ribs about twenty in number, becoming
obsolete at the periphery of the last whorl, spiral striae continuing to the base ;
whorls ten, convexly rounded, the first few shouldered posteriorly, irregularly vari-
cose ; varices four or five in number, about twice the width of the ribs and with their
surface transversely striated ; outline of the spire slightly curved ; sutures well-
impressed ; aperture oval ; columella indentedly curved ; inner lip straight, very
slightly recurved at base.”

LECTOTYPE (here selected) : B.M.(N.H.) Reg. No. 1962842. Length, 12:5 mm. ;
diameter, 3 mm.; aperture, 2mm. Five paralectotypes (1962843) (all broken) :
length, 11-14 mm. ; diameter, 3-4 mm.

REMARKS: The shell is slender, turriculate, and translucent white. The pro-
toconch consists of one and one-half inflated, white whorls which are slightly
crenulated abapically. There are nine spire whorls which are distinctly convex and
separated by constricted sutures. The spire whorls are marked by well-developed, al-
most vertical, axial ribs of which fourteen occur on the first spire whorl and increasing
numbers on the succeeding whorls, with twenty-two on the last whorl. The ribs are
crossed by smooth, low spiral cords of which there are approximately ten on the last
whorl ; the cords are separated by smooth spaces almost the same width as the cords
themselves. In addition to the sculpture, the whorls are also marked by two to
three small varices which may be continuous from one whorl to the next. The base
is rounded and marked only by spiral cords, the axial ribs having become obsolete.
The aperture is oval and the adapical angle is obtuse. The outer lip is thin ; the
inner lip is sinuous.

Of the six specimens comprising the set, only one still possessed the protoconch,
and it was selected as the lectotype.

HOLOTYPE: B.M.(N.H.) Reg. No. 1962844. Length, 3mm. ; diameter, 1-5 mm.

REMARKS : The holotype is much eroded and discolored. The shell is small,
broad, and white. The spire whorls are barely convex ; the sutures are only faintly
impressed. The spire whorls are marked by smooth axial ribs, of which eight occur
on the apical whorls and eleven on the last whorl. The interspaces between the ribs
are gently channelled. The aperture is oval, with a sinus at the adapical angle.

‘The outer lip is thickened by a ridged rim the basal margin of which is reflected out-
ward. A thin callus covers the parietal region.

This is a very common species, dead in beach drift and living in large numbers
under stones in tidepools and in shallow bays in the Hawaiian Islands.

diameter, 3:5 mm. ; height, 2 mm.

REMARKS: The shell is small, thin, conical, elevated and narrowed anteriorly
with the apex anterior to the middle. The anterior slope is short, straight or con-
vex ; the posterior slope is long and may also be convex. The orifice is long, narrow
and trilobate. The surface is dull and the sculpture of narrow, close-set, nearly
equal radiating ribs which are crossed by concentric, raised threads forming small
nodules where they intercept the ribs. The margin is finely denticulated. The |
interior colour is like that on the outer surface, with the green rays mentioned by
Pease showing through.

There are two lots in the Cuming collection, one of four specimens and the other —
of five, but there is no indication as to which might have served as the type series.
The lectotype was. chosen to best represent Pease’s description of “ colour white,
rayed with light green’’. The species is variable in colour, however, the type lot
ranging from pure white to mottled grey, as do specimens collected alive.

This species is common under rocks in the inshore waters of the Hawaiian Islands.

ventricose, longitudinally ribbed ; ribs seven or eight, transversely ridged ; ridges
somewhat distant, becoming nodulous on the longitudinal ribs ; interstices finely
ribbed, transversely and very finely striated longitudinally, squamate, more particu-
larly at the base of the body-whorl. Whorls ornamented at the sutures with a row
of prominent, erect, squamate scales or spines ; lower part of last whorl contracted
towards the base. Colour reddish brown ; nodulous portion of the transverse ridges
yellowish white ; scales and spines white ; aperture white.

Length 45, breadth 20 mill.”

LECTOTYPE (here selected) : B.M.(N.H.) Reg. No. 1964284. Length, 37 mm. ;
diameter, 20 mm. ; length of aperture, Ig mm. Two paralectotypes (1964285) :
length, 35 mm. ; diameter,1g9 mm.; aperture length, 16-5 mm. ; length, 34 mm. ;

REMARKS : Pease’s diagnosis of the species is adequate. None of the three speci-
mens in what is apparently the type lot has the dimensions noted by Pease, and the
largest specimen in the lot has been selected as the lectotype. The locality given
on the tablet to which the specimens were attached is merely ‘‘ Polynesia ’’; Pease
subsequently noted “* Baker Island ”’ as the type locality.

REMARKS: Little can be added to Pease’s description except that the columella
is covered by a thin glaze which projects over the fasciole as a fine-edged shield. The
three specimens in the type lot are beachworn and the apices either broken or obscure.

A notation on the board to which the specimens were attached cites the locality as

ing ribs intersected by smaller spiral ribs. The type lot consists of two specimens,

_ one of which matches the dimensions noted by Pease almost exactly ; it has been

selected as the lectotype. The locale cited on the board to which the specimens are
attached is “* Sandwich Islands ”’ [H.I.] ; the species is not known to occur in the
Hawaiian Islands.

Pilsbry (1890), noting that Sowerby (1866) illustrated as “ Emarginula clathrata
Pease, Sandwich Islands ”’ a shell which was “. . . much shorter. . . than any in
the two suites before me, received from Pease ”’ gave the Sowerby figure the name of

_ E. subclathrata. Comparison of the specimen illustrated by Sowerby which is in the

collection of the British Museum (N.H.) with the Pease types, and with other speci-
mens of this species, indicate that the Sowerby specimen falls well within the range
of variability of the species, and the Pilsbry name is not necessary. The Sowerby
specimen is also recorded as from the Hawaiian Islands and probably arrived with
Pease’s type lot.

REMARKS: The shell is ovate, not umbilicate, sculptured, and thin in texture.
There are six convex whorls plus the protoconch of one and one-half whorls. The
colour is dark brown, a subsutural band of yellow on the last whorl imparting a some-
what striped effect. The sutures are indistinct. The aperture is auriculate, the
outer lip thin with a single, thin tooth ; there are two plate-like teeth on the parietal
wall, and a third somewhat coarser tooth at the end of the columella. The sculpture
consists of fine spiral striae on the last two whorls ; the four apical whorls are granu-
lar.

The paralectotypes show various colour patterns : the apex is generally light and
the spire dark brown, while the last whorl may have one or more bands of dark brown
and yellow.

REMARKS : The shell is depressed, white, spotted transversely with red, the spots
at the periphery of the last whorl the largest. The sculpture consists of spiral keels,
two on the apical whorl, three on the next whorl, and eight on the last whorl ; a
larger keel alternates with a smaller. The base is umbilicate, the umbilicus apically
bordered by a granular ridge. The columella is broad and spatulate, continuous with
the outer lip. The outer lip is thin, the red spots on the outer surface showing through.
The operculum is thick, calcareous, and multispiral.

This species apparently has an extensive distribution in the Pacific : there are
three specimens labelled ‘‘ Sandwich Islands ”’ in Pease’s hand in the U.S. National
Museum in Washington, D.C., while other specimens from Pease in the collection of
the Academy of Natural Sciences, Philadelphia, Pennsylvania are from Howland
Island and the Tuamotus. I have also seen specimens from the Cook Islands
(Academy of Natural Sciences, Philadelphia, Pennsylvania) and from the Marshall
Islands (U.S. National Museum, Washington, D.C.).

REMARKS : Pease’s description is sufficient to establish the identity of the species.
The two specimens-in the type lot are apparently all that remain of what was
apparently a type lot of four specimens ; the specimens were glued to a board which
has glue spots indicating there were two additional specimens at one time. The

PEASE’S MARINE MOLLUSCS IN THE CUMING COLLECTION 79

specimen selected as the lectotype is apparently adult in that the outer lip is thicken-
ed, while the specimen named as the paralectotype is probably a juvenile specimen
with the outer lip not developed.

The “ Sandwich Islands ” [H.I.], are cited as the locale for the specimens in the
B.M.(N.H.) although Pease named the Kingsmill Islands [Gilbert Is.] as the type
locality in his original description and subsequent discussion of the species (Pease,
1868e). The species is common on small, algal-covered rocks in the inshore waters of
the Hawaiian Islands.

The above species belongs to a group of which the S. twberculatum, Blainv., may be
considered the type. Our species, however, differs from that in being much more
deeply engraved throughout, in the longitudinal ribs being more distinct, and the
transverse striae forming ribs or ridges.”’

Pease. The specimens were apparently collected alive, all containing an operculum
and with the protoconchs intact.

slightly the wider anteriorly ; cream-colour or light reddish-brown ; nodules whitish,
sometimes encircled by reddish-brown rings ; ridges of the same colour ; base white ;
basal ridges edged with reddish-brown, and extremities stained with same colour.

Length 32, breadth 20 mill.”

LECTOTYPE (here selected) : B.M.(N.H.) Reg. No. 1964306. Length, 39 mm. ;
diameter, 23 mm.; height, 17 mm. Three paralectotypes (1964307)>) lengths
26-5 mm. ; diameter, 16 mm. ; height, 13 mm. ; length, 24 mm. ; width, 15 mm. ;
height, 11 mm. ; length, 19-5 mm. ; diameter, 13 mm. ; height 9:5 mm.

REMARKS: The lectotype was selected since it best represents the details of the
description given by Pease. The three paralectotypes are juvenile specimens with
neither the margins nor the basal teeth developed.

C. granulata appears to be endemic to the Hawaiian Islands where it is collected
at depths of 10-20 fathoms.

PEASE’S DESCRIPTION : “Shell pyramidally oblong ; whorls eight, concavely
depressed above, longitudinally nodosely ribbed, ribs about ten ; body-whorl en-
circled by a row of tuberculous nodules, in continuation of the longitudinal ribs ;
aperture open, sinus round and deep ; canal short, wide. Colour reddish brown ;
ribs and base of columella whitish.

Length 11, breadth 43 mill.”
HoLotyPE : B.M.(N.H.) Reg. No. 1964308. Length, 10mm. ; diameter, 4 mm.

REMARKS : There are six whorls plus a protoconch of two whorls. The sutures
are not impressed. The sculpture consists of prominent axial keels rising on the
periphery of each whorl into prominent, elongate tubercles, fourteen on the last whorl.
Except for the tubercles, the shell is smooth. The aperture is pyriform and narrow,
the sinus on the shoulder deep and rounded and arched apically. The columella is
straight with a narrow callous.

This species is common in the Hawaiian Islands, and the holotype is accompanied
by a citation “‘ Sandwich Islands ”’ [H.1.].

LECTOTYPE (here selected) : B.M.(N.H.) Reg. No. 1964309. Length, 15 mm. ;
diameter, 8-5 mm. Two paralectotypes (1964310) : dimensions the same as the
' lectotype.

REMARKS : The shell is fusiform and attenuated at both ends, somewhat angu-
lated at the periphery, and consists of 7 whorls. The sculpture consists of nodose
axial ribs, becoming most prominent in the centre of the last whorl, and obsolete
apically. The shells are black, spotted and banded with fawn ; the black pigment
is principally confined to the axial ribs.

Locale data accompanying the type lot cite the “ Sandwich Islands ”’ [H.I.] but
I am not familiar with the species in the Hawaiian Islands. The species has, how-
ever, been recorded from a number of localities in the Pacific.

REMARKS: Pease’s description is adequate to identify the species. The holotype
is faded, dark brown. The sutures are notimpressed. Of the four columellar plaits,
two are conspicuously large while the remaining two are almost obsolete.

The single specimen in the Cuming collection agrees in all details with Pease’s
description except in size ; the specimen has been designated the holotype for reasons
discussed previously. No locality data accompany the specimen.

REMARKS: The three specimens in the type lot agree well with Pease’s descrip-
tion ; the specimen most nearly matching the dimensions given by Pease was
selected as the lectotype. Ali three specimens are beachworn, two of them con-
taining sand grains in the aperture.

Although the type locality is merely indicated as “ Islands of the Central Pacific %
a note on the board to which the specimens were glued gives the locality as ‘ ‘ Kings-
mill Islands.”

REMARKS : Pease’s description is sufficient to identify the species. Of the three
specimens in the type lot, that agreeing most closely with Pease’s diagnosis has been
selected as the lectotype. The locale accompanying the specimens is “ Sandwich
Islands ”’ [H.I.] which is almost certainly an error since the gorgonid on which this
species is known to occur elsewhere does not occur in the Hawaiian Islands.
