PREFACE.

Since the First Part of the Hand List of Mollusca
was published, Mr. Nevill has been compelled by the
failing state of his health to resign his appointment
as First Assistant in the Indian Museum. Before
his departure for Europe, on the 12th March, 1883,
he had made over to me the manuscript of the
Second Part of the Hand ee which was shortly
afterwards placed in the hands of the printer; but
as the majority of the proofs had to be sent to
Europe to Mr. Nevill for correction, the printing

has consequently been much delayed.

It is to be regretted that Mr. Nevill’s resignation
will prevent any further Parts appearing, until a
qualified person has been found to complete the

work he has so well begun.

JOHN ANDERSON,

Superintendent.

This Javanese form differs from Quoy’s species by the less

and irregular spiral black lines, &c.—Alt. 63, diam. 56 mil.,
agreeing exactly with the above-quoted figure in Conch.—Cab. II.

1 Cambodia (spec. juv.); ex c. A. Morelet, Esq.

Lea describes his species as “scarcely perforate”; his figure
appears quite imperforate. Morelet, J. c., describes Cambodian
specimens as having a large and deep umbilical perforation. He
further notices two distinct forms,—one without bands, the other
banded, with the bands ceasing abruptly a short distance
before the peristome; the former seems to agree with my var.
subglobosa, the latter with my var. subampullacea.

Alt. 705, diam. 694 mil. A form with uniform green epider-
mis, not banded, with white peristome and remarkably depressed
and flattened spire, unlike any figure I can find. Possibly
from Siam, and if so, probably the form called A. celebensis by
yon Martens, and A. turbinis by Morelet.

var. Subampullacea, nov.

2 Perak; coll. Ed. Townsend, Esq.

Alt. 75, diam. 68 mil. Fairly represented by Pl. 19, fig. 1,
Coneh.—Cab. IT, “ A. swmatrensis, Phil.”’, but more “ turbi-
nate”—that is, the body whorl more angularly swollen above—
consequently, not so convexly rounded; the umbilicus, coloured
peristome, and spiral purple bands exactly resemble those of

the figure. I gave a third specimen of this form to Monsieur
H. Crosse.

Long. 23, diam. 19 mil.

This is a very closely allied from to P. javanica; indeed,
probably only a geographical race, and perhaps would be better
classed as a variety of it!

It can, nevertheless, be readily distinguished by the keel on
the last whorls giving the suture a canaliculate appearance, by
the less developed spiral sculpture, by the presence of longi-
tudinal, subobsolete plications, as also by its shorter and more
decollate form, more convex whorls, the last one subangulate,
darker and duller epidermis and blacker peristome, which is
more or less angulate below.

Von Martens would not appear to have met with it, as it
cannot surely be the form he mentions, Mal. Blit. 1865, p. 148,
as a rounded, keelless, extreme variety of P. burroughiana!
One of my specimens approaches Reeve’s fig. 53 (P. carinata)
in the more rounded peristome and less distinct subangulation
of the last whorl.

The animal of Hydrobia [as “ Littorinella”] is generically
distinct from that of Peringia [as “‘ Hydrobia’”], according to
Stimpson. Gray, in Turton’s Manual, 1840, proposed Turbo
ulvae, Pennant, as type of the genus, but this cannot, however,
be so accepted, because it was not one of Hartmann’s original
type species.

Dr. Kobelt joins the sections Jlaresia and Frauenfeldia; but
if this is adopted, the former name must have priority. M. de
Folin has suggested that the group Vitrella may be the same
as his Locardia; M. Bourguignat considers them as distinct:
if they prove identical, both names must yield priority to M.
Bourguignat’s genus Lhotelleria, which is unmistakeably the

This variety principally differs from Schwartz’s figure in the
absence on the antepenultimate whorl of the longitudinal fur-
rows; the characteristic denticulations within the outer lip are
well marked in the Mauritian specimens, they are unaccount-
ably wanting in Garrett’s magnified figure, though “crenula-
tions within the peristome ” are duly recorded in his description !
The Red Sea form is considerably stouter and broader than
any of the other known ones, as can be seen from the above

Possibly better classed as a var. of the preceding, the two
denticulations within the aperture are quite distinct, though
not recorded in Pease’s descriptions. It can always be dis-
tinguished by the markedly shorter spire, more tumid last
whorl, less everted aperture and especially by the ribs on the
penultimate whorl; the above will also distinguish it from
R. coronata, Recl., possibly a mere var. of R. bidentata.

Distinguished by the very distinct basal “canal” [or notch],
twisted columella and sinistrally bent, pyramidella-like apex.
Type Lissoina ? abnormis, Nevill.

Perhaps Alvania bowrquignati, Issel, belongs to this group P

A, Adams (ms.) and von Martens, in Mobius Reise Mauritius,
&c., consider these forms as allied to—or part of—Lachesis.
O. Semper, fide Schmeltz, placed them in the Family Planaxide.
I feel convinced, and I believe Dr. Weinkauff is of the same
opinion, that they belong to the Rissoide and are closely allied
to true Bissoina.

Gould’s description of Alvania fusca, from Hongkong, would
answer perfectly to this form, but is said to have eight whorls
and measure long. 6, diam. 13; mil. Dr. Hungerford’s shell has
only five and a half whorls.

If M. Fischer had made this remarkable species the type of
his Genus Plagiostyla, instead of R. lactea, Michaud, I should
have considered the form as worthy of at least subgeneric
distinction.

I am not clear whether this is, or is not, a distinct species
from the preceding [F’. cerithina|? They seem to me to run
one into the other! Certain it is, however, that Mr. A. Adams
identified as F. scabra, indubitable specimens of F’. cerithina,
which had been dredged by Mr. McAndrew at Suez! The sculp-
ture of the Japan forms appears somewhat coarser, and with
one transverse stria less.

indeed the two species are perhaps scarcely more than geo-
graphical races P Three of the above agree with Reeve’s fig.

Very closely allied to L. obesa, but smoother and of different
coloration. They may be only varietal forms? These speci-
mens are most admirably and exactly represented by Philippi,
III, Pl. VI, fig. 6, as DL. levis, Locality? The L. levis of
Reeve, I need scarcely say, is a totally different Australian form.
Prof. v. Martens would rather consider Z. levis, Phil., as a form

Profs. v. Martens and Hutton do not appear to have noticed
this form, so admirably represented by Philippi. In colora-
tion it much resembles L. diemenensis and has been confounded
with it by some authors? The shape is quite different, the
spire being more elongately produced, &c.- In some respects
it also resembles Reeve’s figure of L. levis. It is smoother and
more regularly pyramidical, &c., than the preceding.

Fischer records the species from New Caledonia, but I should
imagine this form would rather be a variety of L. intermedia,
if indeed the two species can be kept apart ? Von Martens in

pintado ; this can hardly be the case.

T am very loath to adopt this species as distinct; the differ-

Phil. and L. philippiana, Reeve, are the nearest I know; the
more convex whorls, thinner substance, absence of keel at
the periphery, and the rather peculiarly “ excavately appressed ”
columella seem, however, characteristic! In size and color-
ation all five of the above resemble the type.

var. delicatula, nov.

30 Port Canning and False Point (Bengal) ; coll. Colonel G, B. Main -
waring, G. Nevill, Esq., and Dr, F. Stoliczka.

Perhaps the most beautiful marine shell, when living, that
I have ever seen. The colours fade terribly after death; it is
most difficult to get perfect specimens and it appears to be
remarkably local. The variety can be distinguished by its
extreme fragility, by the much less developed peripheral keel,
less obsolete sculpture, and especially by the more rounded
columellar margin at base; it varies wonderfully in colour,
from a beautiful rose to the typical straw colour, oftentimes
marbled or striped. JI had separated the above from the
following specimens as a distinct sub-variety, when I found two
tubes in Dr. Stoliczka’s collection, marked “¢ and 9?”’; that
marked 2 contained six of the preceding and one of the fol-
lowing specimens [the last probably inserted erroneously ? ] ;
the other tube marked ¢ contained eight, all of the following form.

150 LITTORINIDA.

Here perhaps is an explanation of some of the differences
in allied forms? Can, for instance, my Singapore specimens
catalogued as L. pallescens var. erronea, and those as L. arbori-
cola var. philippiana, be the different sexes of one species ?

Long. 16, diam. 975 mil. [Generally a little smaller. ]

The differences from the typical form are probably due to
my var. delicatula living in slightly brackish water? Reeve’s
L. tenwis from the Philippines seems to be an allied form P

20 Port Canning and False Point; coll. Colonel G. B. Mainwaring,
Dr. F, Stoliczka, J. Wood-Mason and G, Nevill, Esqrs.

Of equally fragile texture, but easily distinguished from the
female form by the less produced spire, even less developed
keel at periphery, and especially by the conspicuously distended
aperture and rounded columellar margin at base; several speci-
mens have one or two varices behind the peristome, which is
occasionally ‘subduplex.” The coloration is, if possible,
even more beautiful and variable! Long. 14, diam. 82 mil.
Gibbons, Q. J. Con. 1878, p. 339, states that specimens of Lit.
intermedia and angulifera become less solid as the water in
which they live is less salt; I am not sure that this applies to
the form under consideration as immediately associated with
my var. delicatula, may be found normally solid Lit. inter-
media and the very thick-shelled Lit. melanostoma.

Philippi’s figure is unmistakeable, whereas Reeve’s, fig. 93, is
very indifferent. The sculpture is very variable, occasionally
unusually developed. Mr. Smith, P. Zool., S. 1878, appears
to consider this Andaman form as L. ven/ricosa and compares
it with his L. melanacme and L. novae-zelandie.

Long. 9, diam. [vix] 8 mil. This form, exactly represented
by Frauenfeld’s fig. c., of coarser sculpture than the type, is un-
doubtedly only a var. of L, ventricosa; if it prove to be Gray’s
species, as I expect it will, this latter name will have priority.
The specimen, from the same province of Ceylon as the next
form, DL. nove-zelandie, has induced me to believe the latter
a distinct species? I can perceive, however, no difference
except that of sculpture, and the shorter, more ventricose form
of L. ventricosa and its var. subgranularis, both characters very
variable in this species.

IT am convinced this species was never found in New Zealand.
Prof. F. W. Hutton in 1878 records that he had never seen
specimens. As to the localities of Reeve and von Frauenfeld

LITTORINIDA. 153

[Auckland], they are utterly without value in my eyes; the
latter’s specimens probably came from Madras? The above
recorded specimens are a constantly much smoother form than
L. ventricosa, with even less marked coloration and distinctly
more produced spire in all cases, though this last is a variable
character in both species. EH. A. Smith describes a closely
allied, but more compressed form, from the Solomon Islands,
as L. melanacme, P. Linn. Soc. XII, 1876, pl. XXX, fig. 21;
this may be the L. nove-zelandie of Fischer from New Cale-
donia ?

Long. 10, diam. 8 mil. Very variable as regards sculpture,
sometimes only spirally striate, occasionally more or less dis-
tinctly granulose ; it can always be easily distinguished from
L. ventricosa, which lives with it, by being always angulate at the
base of the aperture, instead of rounded. It is a larger, coarser
variety than the Ceylon form, and may be specifically distinct ;
it can be easily distinguished by the more regular spiral sculp-
ture and its sombre coloration, wanting the characteristic
black and white “ filleted”’ bands [as seen also in Philippi's fig.
of L. leucosticta]; it is as much like Philippi’s figure of L.
subnodosa as that he gives of DL. nodosa, Gray. Reeve’s
fig. 13 of L. nodosa fairly represents some of the Hongkong

specimens.

A species from the Loyalty Islands has been described by

160 LITTORINIDA.

Judging from this singie specimen, a very distinct small
form. Sub-tuberculate above, striate [instead of sulcate |
below. Perhaps the form described by Smith, 1. c., as found by
Brazier at the Marshall Islands.

var. [? dist. sp.].

Long. 3, diam. 2? mil. Differs from the Arakan form of

with more regular and more numerous spiral sulcations.

are perhaps not quite adult? Descr. de l’Egypte, Pl. V, fig. 40,

10. Risella [Peasiella] templiana; n. sp.

Exceedingly variable in coloration and sculpture; seems,
however, to be constantly distinguished from the preceding
forms by its considerably more open umbilicus, constantly stained
of a rich chesnut; the columella seems to be more distinctly
thickened and is of the same colour ; the form I take for my type
is evenly, spirally striate above, striation more or less obsolete
on the apical two or three whorls; aperture of a uniform saffron
yellow within ; no subimbrication, or peculiar sculpture of any
sort, at the suture; three or four deeply excavated spiral sulca-
tions at base. Long. 33, diam. 4 mil.

the suture ; undulately ‘“‘ waved ” or subimbricate at the suture,
as in Deser. de l’Egypte, Pl. V, fig. 35, which indeed gives
perhaps a better idea of this Andaman species than of the
Red Sea form; intermediate forms will probably occur to
connect the two ?

a minute striation can be detected. The umbilical perforation
is very small.

Long. 23, diam. 24 mil.

Of the usual ‘“ turbinate” shape, consisting of four whorls; the
apical two are smooth, the third has two prominent raised spiral
keels, coarsely, nodosely reticulated ; the last whorl convexly
ventricose, with eight spiral keels, nodosely granulated and with
the interstices longitudinally striate; umbilicus more open
than in the Japan species, peristome slightly fimbriate. Dr.
Hungerford has dredged a closely allied form at Hongkong.

5. Conradia adamsiana, n. sp.
1 Oman, Persian Gulf [type]; coll. W. 'T. Blanford, Esq.

Long. 1, diam, 1 mil.

Turbinate, of 34 whorls, the apical ones smooth, the last but
one with two raised spiral keels, the last with five. I can detect
no longitudinal striation whatever, the interstices consequently
appear to be quite smooth; behind the peristome, which does
not appear to be fimbriate, there are two conspicuous, thickened
labial “‘ varices”; the umbilicus open, much as in the preceding.
Altogether a very distinct though so minute a form! The Red
Sea specimen, which though also in good geondition is probably
scarcely adult, agrees exactly with the type, except in want-
ing the characteristic ‘“‘labial varices” and in that the peris-
tome is distinctly fimbriate ; it also shows no signs (under the
lens) of any longitudinal or reticulate sculpture. Named
in honour of the late Mr. Henry Adams.

186 PLANAXIDA,

If Mr.:Smith had been able to examine as many specimens
as I have, he would have found that none of the characters he
relies on are constant; e. g., it is not smoother than many of
the Persian Gulf specimens ; the sulci are of exactly the same
width ; and the coloration recorded is not constant. Curiously
the typical coloration is also exactly represented by typical
Persian Pl. breviculus. The “basal canal” likewise is often,
if not generally, entirely like that of its allies !

The habitat is very interesting, being the only one known
East of the Bay of Bengal: it is particularly important to find
the species actually living with Pl. sulcatus. The fig. of Pl.
encausticus in the Con. Iconica is very fair, but fig. 30, a “ Pl.
savignyi,” has the last whorl less tumid than is usually the
case.

3. Planaxis breviculus.

Coloration close to that of the original figure, also to that
of the Arakanese Pl. savignyi, var. encaustica. Pl. breviculus
is scarcely more than a well-marked variety of Pl. savignyi ?
The darker-coloured aperture, however, with obsolete liration,
seems to be characteristic.

Both these and the preceding have a more acuminate spire
than in the figure of Deshayes. The figure in Con. iconica
seems to me different again; possibly it represents Pl. brevis,
Quoy, as Sowerby quotes the latter’s localities—* Guam and N.

The figures 11 and 12 of the Con. Iconica, * Pl. similis and Pl.
hanleyi, Smith,” both resemble more closeiy the original figure
of Krauss than does fig, 9, “Pl. acutus”. I consider Smith’s
Pl. similis doubtfully separable even as a variety. The species
varies much in size, and tendency to subangulation at the peri-
phery. Pl. ater, Pease, is scarcely more than a geographical race

or variety.

Planaxis nicobaricus, von Frauenfeld, Moll. Novara Hap. 1866, Nicobars—
long. 12, diam. 8 mil., anfr. 6; Con. Iconica, fig. 13, as Pl. niger [not
Pl. niger, Quoy |.

Prof. von Martens, Zool. Record for 1866, p. 182, says of
this species—‘‘ Most closely allied to Pl. nucleus [Brug.] and
P. ovatus [ Krauss ].”

There seems to be considerable confusion about this form.
Sowerby figures it excellently as above, but confused it with a
species of Quoy’s not half its size, and consisting of four whorls
only. Von Frauenfeld’s description and figure do ‘not at all
well represent the species. I imagine they were taken from a
dead and worn specimen, in bad condition.

Whorls either six or seven, the upper ones perfectly smooth and
of lighter colour, the last two under the lens obsoletely striate,
the last of all so much as to be almost smooth, except for an
incised infrasutural girdle, and some five or six broad sulcations
quite at the base. A good characteristic is the unusually sharp
pointed apex. The shell varies from a rich chocolate colour to
black and is covered with a rather thick, compact, lighter
coloured epidermis. The aperture is remarkably expanded or
“patulous,’ of a uniform rich brown colour, not margined at
peristome, denticulations within so fine as to be often almost
imperceptible even with a lens.

Long. 12 to 14, diam. 7 to 74 mil.

These are of a rich brown colour and consist of seven whorls ;
spire more acuminate than in the next form.

7 Maré, Loyalty Islands ; ex c. F. Layard, Esq.

It was, I suspect, one of the specimens from this locality, out
of Mr. Hanley’s collection, that was figured by Sowerby in the
Con. Iconica ? They are almost quite black, of six whorls ; two
have a peculiarly shortened spire and may belong to a distinct
corm,

Long. 12, diam. 7 mil.

base” ;=P. ahbreviatus, Pease, P. Zool. S., 1865, Central Pacifie—
long. 10, diam. 6 mil.

It would almost seem as if the description and figures of
Quoy applied to two distinct species, the former undoubtedly
referring to this species and the latter resembling more closely
the preceding (except the line denoting natural size, which
reters to the former) ?

5 Tahiti; coll. H. Pease (typical Pl. abbreviatus) and ex Mus. Godeffroy.

Spire short, obtuse, and corroded; four whorls, 3—4 sulca-
tions at base of the last whorl; jet black, with aperture much as
in preceding specimens, denticulations being almost obsolete, but
a good deal more developed than in Tahiti specimens, which
also have the last whorl more tumid; tooth above columella
remarkably developed in this specimen, much as in fig, 12 of
Con. Iconica.

28 Baalbeck and Rv. Litany [—Leontes] ; coll. Dr. J. Anderson [16}, 9].

Even more convexly rounded than Brot’s pl. 45, fig. 4, with
the last whorl relatively unusually short; and lighter substance
than usual, with callosity less developed.

var. variabilis.

Melanopsis variabilis (von dem Busch), Philippi, Abb. If, 1847, Schiraz

and Persepolis.

Judging from M. Brot’s figures, this variety is not M. min-
grelica, Bayer, as I suspected from Issel’s description; the
latter’s var. carinata must bear close affinity to my subvar. acute-
carinata.

30 Persia; coll. W. T. Blanford, Esq. [24, 10].

From neighbourhood of Shiraz, I believe ; the original figures
of Philippi are excellent, those of Brot very bad. These are
what I consider typical specimens, resembling Philippi’s fig. 8,
“anfr. planiusculis.”

M. Bourguignat’s pl. XV, fig. 25, Malac, Alger, gives a fair
idea of this interesting form, which, however, is smaller, not
decollate, of paler colour, obsoletely banded, with the keel even
more developed.

subvar. decollata.
Philippi, l. ¢., fig. 7; ? M. fasciolata, Parreyss.
20 Persia; coll. W. T. Blanford, Esq. [19, 9].

A very distinct, thin, eroded, slightly decollate variety, whorls
usually less convex than in the quoted figure; under the lens
minutely, flexuously striate; two or three show distinct, longi-
tudinal, distant ribbing as well, much as in Rossm., fig. 1883
[M. tingitana, Morl.]. It is perhaps as closely allied to Issell’s
M. dorie,—seems, indeed, to be a connecting link.

MELANIID. Pali

Seems to me intermediate between M. prerosa and M.

the shape of the last whorl and less expanded aperture (at base)
show a closer affinity to the former species,

cousiders the form as distinct, and that M. maresi, Bourg.

I have followed Messrs. Brot and Adams in adopting the group
of M. hastula as the typical section, although I consider that
of M. amarula, Bolten’s Genus Tiara, would have been more
correctly adopted.

1, Melania fuscata.

Helix fuscata, Born, Test. Vindob. 1780, “ Virginia” [not of the Con. Indica];
var.—WM. macrospira, Morelet, Test. nov. Austral. 1857, N. Caledonia.

I am unable after a long and careful comparison of numerous
specimens of both, in all stages of growth, to separate the Fijian
and Nicobarese forms. I can see no constant difference what-
ever, except the more conspicuously marginate suture, nor can
I find any distinctive characters for the New Caledonian form ;
individuals vary in the slightly more or less convex shape of
the whorls. It is very likely that Born’s types of both M.
fuscata and M. maculata came from the Nicobars.

4 Nicobars ; coll. F. A.de Roepstorff, Esq.

From Nancowry, I believe; M. Brot’s pl. 17, figs. 4a and 5,
give a fair idea of them.

3 Nicobars ; coll. Dr. F. Stoliezka.

Agree well with Born’s original figure [—Brot’s pl. 18, fig. 2];
also Brot’s pl. 17, fig. 4 [M. aspirans], and one resembles his
pl. 17, fig. 4 A. This I consider the young of the form.

5 Katchall ; coll. F. A.de Roepstorff, Esq.

Probably a more adult form of the preceding, well represented
by Brot’s pl. 16, fig. 7 A. [M. maculata, var.], which I expect
is also a Nicobar specimen. There is a great tendency to
deformity in this race; one of them is twisted like Hulima
arcuata. Reeve’s fig. 57 [“ M. acutissima ”’—pars] also pro-
bably represents this form.

var. aspirans.
Melania aspirans, Hinds, Ann. Mag. XIV, 1844, Fiji Islands, axis 23 lin,

5 Ovalau Fiji; ex c. F. Layard, Esq., &e.

Mr. Layard’s two specimens were labelled ‘‘M. jigurata,
Hinds,” a species from New Ireland, which also proves to be
only a variety of this widely distributed species. Brot’s pl. 17,
fig. 4, though somewhat larger, well represents the above
specimens. The variety, so far as I can see, is only really
characterized by the more marked margination of the suture.

A very variable and widely distributed species; M. Brot’s

from the Nicobars,

One specimen of 4 whorls measures long. 30, diam. 12 mil.,
andis well represented by M. Brot’s pl. 21, fig. 16a, the apical
whorls of course being left out of consideration ; the other of
3 whorls, and the internal portion of a fourth has the last
whorl more convex, with a slight infra-sutural shelf; long. 30,
diam. 13 mil. M. Brot’s pl. 21, fig. 16, though smaller and with
the last whorl more cylindrical, gives a very fair idea of it ;
both are of uniform coloration.

2 Camorta? ; coll. F. A. de Roepstorff, Esq.

One is a quite young specimen of 7 whorls, slightly decollate,
as in Brot’s pl. 21, fig. 17; the other of medium growth, has
© whorls remaining, none of which show the apical sculpture
as does the preceding. I have little hesitation in referring both
of them to this variety as non-adult forms.

The only difference from the following two specimens seems
to be that the apical sculpture is rather less developed.

2 Katchall [?] ; coll. F. A. de Roepstorff, Esq.

A very interesting form, fairly represented by the above
figure, though the last whorl is relatively rather shorter still.
The apical 8 whorls are very prominently and regularly longi-
tudinally ribbed and spirally striated; last whorl, of course,
smooth at base; of uniform dark olive-green coloration. I
cannot help thinking they are from Great Nicobar like the
preceding.

MELANIIDA. 227

Well represented by M. Brot’s fig. 2 and Reeve’s figs. 57 and
58, but smaller and evidently not quite adult. It is important
to be able to establish the true habitat of this species, as I am
now able todo. The species resembles in many respects the
form I have catalogued as M. wrea? Reeve, in coloration,
size, and the characteristic, forcibly reflected, thickened columella
[exactly similar in both]; the apical spiral striation is, however,
less distinct, but, above all, the whorls, instead of being unusual-
ly convex, are almost cylindrical, as in Reeve, fig, 57. The last
whorl is distinctly subangulate, as mentioned by M. Brot in
his invaluable work. The brown maculations resemble those
of Reeve, fig. 57, though rather less distinct.

var. perstriatula, nov.

2 Guam; ex c. Prof. W. Newcomb [labelled “ M. hastula’’].

Wonderfully close to the preceding, but with more developed
and regular spiral striation, only obsolete in the middle of the
last two whorls; coloration uniform, last whorl subangulate,
upper whorls more attenuately produced. Long. 30, diam.
8 mil,; anfr. 12.

Long. 35, diam. 103 mil.; anfr. 10.

This can scarcely be the M. tristis of Reeve, as the upper
whorls are spirally striate, and the columella is strongly callously
incurved, even more so than in Mousson’s pl. XI, fig. 5 [‘ M.
aspirans”’|; it differs from the latter by the more ventricose
last whorl, the shorter and more convex spire, &c.; the last
whorl is smooth, scarcely striate even at base; slightly maeu-
lated with brown streaks in young specimens only. Brot’s pl. 19,

228 MELANIID&.

fig. 4a [M. erea], gives a good idea of the shape of the form,
only the columella is not sufficiently bent back. Reeve’s original
figure, however, seems to me scarcely the same species. Reeve’s
fig. 58 [M. acutissima] also closely resembles it.

10. Melania subula.

especially being less ventricose. Two are of a uniform dark-
violet colour throughout; the third agrees exactly with the
original description, and has the paler band next the suture, with
short flames, &c.

I can find no figure to represent this well-characterized form
amongst M. Brot’s illustrations of M. hastula ; it is nearest fig.
3, but much smaller, with the apical ribbing more distinct.

Perhaps his pl. 16, fig. 2a [M. acutissima] best represents it ;
indeed, I have felt tempted to refer it to that species, as it
resembles remarkably closely the Luzon specimen I have already
recorded, only it is a more solid shell, with distinct, though not
prominent, longitudinal ribbing on the apical five whorls, instead

a variety. The sutures are excavate, slightly swollen beneath,

than in any of the preceding forms ; though adult, it is scarcely
decollate ; coloration uniform brown; spiral striation very

Dr. Hungerford sent these specimens mixed with the pre-
ceeding. I think, however, they must be distinguished, as they
are of a uniform sombre coloration, without any sculpture
whatever; they are of all stages of growth, but still are in all
cases decollated and eroded; M. Brot’s pl. 24, fig. 3A. [“ M.

Very variable, as regards sculpture; some have distinct
longitudinal sculpture near the apex, which in others is almost
or altogether obsolete; there are 1 to 3 spiral, incised strie on
the lower portion of each of the last few whorls. The basal
band is less distinctly marked than in Mousson’s figure,—indeed,
generally not visible at all within the aperture. A single
specimen is of a uniform dark-violet colour; several are slightly
maculated with brown; these resemble very closely M. tigrina,
Hutton.

6 Camorta ([?]; coll. F. A. de Roepstorff, Esq.

A close ally of M. nicobarica, constantly, however, distin-
guished by the almost cylindrical instead of more or less convex
whorls, the upper ones not abruptly attenuate, and the last one
not tumidly swollen; the sculpture is very similar, but the
markedly more strongly incised spiral striation at the base
whorls appears to be characteristic.

var. andamanica, nov. [vel M. andamanica, n. sp. ?].

Possibly a distinct species, though at present, I believe, it is
correctly classed as a local variety of M. nevill. It is at once
distinguished by the upper three or four whorls being invari-
ably longitudinally ribbed, the ribs being not at all prominent
and slightly but distinctly arcuate; quite young specimens
show this ribbing throughout, the ribs only becoming obsolete
on the lower portion of the last whorl. Generally but slightly
decollate, eight whorls remaining; covered with a rust-brown
coating, beneath which the shell is light green, irregularly and
very slightly spotted with brown below the suture; throughout
spirally striated; a single specimen only has this spiral sculpture
obsolete on the central portion of the last two to three whorls.
Themajority of specimens are smallerthan type figure of M. nevilli,.
and have the last two whorls increasing much more rapidly in
breadth, in this more resembling M. Brot’s pl. 22, figure 8B;
the last whorl is, however, never convexly swollen as in M,
nicobarica.

Well distinguished by its produced and fusiform’shape; the
whorls increase regularly and are more convex than those of
the type form, in which the upper whorls are abruptly and con-
tractedly attenuate, the lower ones increasing rapidly in size,
especially the last, which is always very tumid. In var. fusi-
formis, on the contrary, it is only a trifle more swollen than
the preceding one. More solid and of brighter coloration ; sculp-
ture rather less distinct.

This locality requires confirmation. I believe it to be al-
together distinct from Mel. nicobarica, but place it here tempo-
rarily until the exact locality is authenticated. Itis of a light
green colour, obscurely spotted with brown below the suture ;
whorls much more convexly rounded, columella being corre-
spondingly twisted back ; the apical whorls are less numerous
and less attenuate, spiral striation less regularly and deeply
incised, altogether or almost obsolete on the upper portions of
the last few whorls; under a lens the first few are minutely
decussated in the interstices. It appears also to be closely
allied to a form found by Baron v. Richthofen, which I have
recorded as M. wrea, Rv. var.

like some species of Hulima and as well shown in the above
fig. 2A. The sculpture is much more prominently developed,
more uniform, otherwise not unlike that of fig. 1A, lL. c.
Brot’s pl. 33, fig. 2, evidently represents one of this form,
although the sculpture of the last whorl is more conspicuous
than in my specimens. I consider this species as very closely
allied to M. tuberculata.

M. Brot seems to imply, 1. c., page 250, that the Nile form is
the typical one; this is erroneous. The exceedingly common
Madras form is clearly pointed out by Miiller. It does not
appear to be figured by M. Brot; the Con. Indica, pl. 75, figs. 1
and 4, give a good idea of it. M. Brot is altogether mistaken
in his views as to M. tigrina, Hutton, and M. pyramis, Benson,
which are perfectly correctly identified and excellently figured
by Mr. Hanley on plate 110 of the Con. Indica.

tinct, much as in typical M. gloriosa, but more crowded ; like
the typical form, it is throughout regularly, though indistinctly,
spirally striate. There are three specimens also in the collection
of Mr. H. F. Blanford, and on the same tablet, presumedly
from the same locality, ‘‘ Henzada,” a single specimen of M.
reevei. It is very interesting to find the two species living
together; this occurrence is confirmed by the specimens from
Dr. Stoliczka’s collection, wherein I found the two above-record-

relatively even more solid; appears to be perfectly smooth

Prof. Brot apparently does not know this species, as he con-
fuses it witha mere local race of Mel. variabilis ; this he figures,
pl. X, fig. 1, as “typical” Mel. herculea. On the same plate,
fig. b, he figures a young specimen of the true Mel. herculea,
and remarks quite correctly that it is the M. hercuela, var.
sowerbyt, of the Con. Indica. Moreover, he redescribes, most
excellently, a local form of it as a new species—M. julient, Des-
hayes, MS., from Tonkin.

Reeve’s fig, 10 A, “ M. corrugata, Lamarck, India, &c.,” may,
perhaps, represent this form, though it has the semi-nodulose
sculpture a little more developed. M. Brot’s pl. 10, fig. la,
is close, but doubtfully identical; unfortunately, as in many
other instances, he does not record the exact locality. The
present form is more decollate, the ribs are straighter, a trifle
further apart and more developed. The only figure that well
represents it is that of the Voy. Bonite, pl. 31, figs. 11-12, la
“ Melania indienne” from the Ganges, = Melania varicosa,
Troschel, in text, 1. c., not M. indica, Soul., as stated by Brot,

gradual transition to the WM. episcopalis, Lea, which lives in the
same neighbourhood.

Var. D. Benson, |. c., ‘‘ Anfractuum superiorum costulis obso-
letis, ultimi et penultimi liris transversis costulis longitudi-
nalibusque superne serie duplici nodulosis.”

A very interesting form, admirably described by Benson,
moderately decollated, upper whorls perfectly smooth, last two
girt with a double row of prominent regular nodules, more or
less subobsoletely spirally striate at base of last whorl, one rib
about the centre [starting from top of the aperture] always
prominent, the two rows of nodules are joined by longitudinal
ribs, more or less obsolete; the above described sculpture of
the two last whorls is sometimes nearly or partially obsolete ;
in not a single specimen do I find traces of sculpture on the
upper whorls. Brot’s above-quoted figure is a fair representa-
tion of the form ; in shape it is exactly the same. Cachar speci-
mens are more decollate, have the sculpture terminating even
more abruptly, nodules a little more distinct ; it is very inter-
esting to find this characteristic variety repeating itself, if I
may use the expression, in Sumatra. I need scarcely say
M. Brot’s other figures of his M. sumatrensis (except his pl. 13,
fig. 1b, which may be the young) represent widely different
forms.

15 Cachar and Sylhet [type var.] ; ex c. Asiatic Soc., Bengal.

The M. infracostata, Mousson, from Java and M. brooket
from Borneo may possibly all prove to belong to this variety,
as mere local races ; slight differences in sculpture of the last
two whorls being their only distinguishing features, apparently.

one, as he makes the basal sulcations far too developed. Lea, in
his description, notes that “ one of his younger specimens has a
disposition to indistinct folds towards the apex.”

This widely spread and variable form is not the Mel. episco- .

Why M. Brot would not accept Hanley’s typical figure in his
Conch. Misc. of M. episcopalis, which nevertheless agrees fairly
not only with the original description, but also with Brot’s Ma-
lacca specimen [ pl. 12, fig. 1] and my Perak specimens from the
same district, I am quite unable to understand; possibly,the subse-
quent series of errors in the Con. Indica induced the Professor
not to do so. These errors are that Hanley figures the epis-
copalis of Lea for his own Mel. spinosa, and the true spinosa
as “MM. menkiana, Lea” [and subvar. as M. hanleyi, G.-A.].

which, again, is more central.

perfect spire, and whorls less convexly swollen; two brown
bandsat the base, as in typical var. B., but the upper whorls also
possess a distinct central band; two specimens have subnodular
ribs on the last two whorls, the upper ones being perfectly smooth,
the third specimen has nodulose ribs on the three last whorls,
the fourth has them on the last whorl only; these nodulose
ribs are variable in number and relatively distant.

41. Melania [Melanoides] spinata.
Melania spinata, Godwin-Austen, P. Zool. 8. 1872, Kopili River.

This remarkable form, excellently figured by the author
[pace M. Brot], preserves its characteristics in both young and
adult. M. Brot makes the strange error of supposing it might
be the young of the form figured [correctly] as M. episcopalis,
Lea, in the Con. Indica ; I have both forms in all stages, and
need scarcely say that they are widely different. Possibly, indeed,
it might also be classed as an extreme variety of M. variabilis ;
the peculiar, ‘“‘foliaceous”’ tubercles are very characteristic.
It bears also some resemblance to a form of Mel. baccata, Gld.

was not considered necessary to “mount.” Two are of a small,
dwarf race, and three are not decollate, in this state resembling
very closely the Halmaheira specimens.

The synonomy of tliis species is correctly given by Mr. Hanley
in the Con. Indica; M. Brot, on the other hand, has evidently
not had the “‘ Gleanings of Science” to refer to, or else he would
have found the name of Melania lirata is not mentioned therein.

Unfortunately, I have no record concerning this specimen,
well represented by M. Brot’s pl. 30, fig. 2 [M. moreleti];
the body whorl is smoother and less ventricose, spire more
exserted than in young Mauritian specimens,

A very fine form, near M. Brot’s pl. 29, fig. 1A.
5 Mauritius ; coll. G. Nevill, Esq.

The typical form well represented by M. Brot’s, pl. 29, fig. 1.
Despite M. Brot’s valued opinion [1]. c., p. 291], I think I may
state positively that Deshayes’ M/. moreleti is the young of the
typical form, notwithstanding the remarkable “ quasi” adult
appearance that it invariably presents. These young specimens
agree well with pl. 30, fig. 2A, 1.c.. Dr. Moerch considered a
form from the Moluccas as the true Mel. amarula.

Larger ; some agree with fig. Id., some with fig. 3B., and
others again are intermediate. This variety Dr. Mcerch con-

Melania cybele, Gould, P. Bost. S. 1847, Fiji, Navigators’ Islands, &e. ; fide

I doubt if Mel. diadema, Lea, from the Philippines and
Amboyna, should be specifically separated. Dr. Meerch consi-
dered Mel. crenularis as distinct; he does not mention either
Lea’s or Gould’s species.

Melania amara, Moerch, J. de C., 1872, Little Nicobar, for Mel. mitra, Reeve
[not of Meuschen], Sumatra.

1 Great Nicobar ; coll. F. A. de Roepstorff, Esq.

Apparently very local, as I have only seen two specimens
from the interior of the island. It is a beautiful form with
pink-tinged collumella, and is exactly represented by M. Brot’s
pl. 29, fig. 2 C. [“* M. diadema,” Lea]. The writer classes Mel.
amara as a synonym of Mel. cybele ; doubtless he had not seen
an authentic specimen. Reeve’s figures 175 b. c. from Sumatra,
though larger, are also very close.

M. Brot unites, as a variety, the forms from Ceylon figured
in the Con. Indica, pl. 110, fig. 7 as M. scabra, var. spinulosa
and fig. 10, as WZ. acanthica, Dohrn ; this is, I think, more than
doubtful, as also, I consider, is his statement that the three forms
are found together ; this is quite opposed to all I know on the
subject, and it would be desirable if the Professor would give
his authority for the statement.

M. Brot, on page 269, correctly quotes “‘ I. Negros ” [ Philip-

on page 268, however, he says that .M denticulata, Lea, from
‘“ Afghanistan,” is not separable ; but the species figured for M.
denticulata by Reeve is from the “ Philippines,” and probably
belongs to Mel. pagoda, Lea.

MELANIID&. 283

Well represented by Con. Indica, pl. 73, fig. 1. Some have
the spines moderately developed, as in the Madras specimens
already noticed. A single abnormal specimen has the spines
remarkably duplicated, in a “ frondulose” manner.

13 Balapiti, Ceylon ; coll. G. Nevill, Esq.

I consider Mr. Hanley is undoubtedly right in uniting this
form to Mel. scabra, the transition from the one to the other
being clearly traceable.

Found in a well. This remarkable “ habitat” confirms Cap-

ribs on the last whorl are less developed.

Labelled ‘“‘ Mel. australis, Reeve, Australia.” I may take this
opportunity of warning European conchologists against the
labels, identifications, &c., of the Madras Museum: I have

found both equally untrustworthy.

Sub-Genus MAINWARINGIA, nov.

Type M. paludomoidea, n. sp.

A new generic form, apparently connecting Melania and
Paludomus, distinguished by the presence of rows of hairs or
bristles, especially noticeable on the body whorl, which is
ornamented with broad revolving brown bands ; not umbilicate ;
apex remarkably acute, “quasi styliform”’; peristome acute,
columella thickened and excavately inflected. Operculum
transparent, of one substance throughout,—that is, without any
thickened process for attachment,—of very light horn-colour,
without sculpture, ovate, acuminate at one end, at the other
rounded, and distinctly terminally subspiral, with 2; whorls,
closely resembling Adam’s pl. XXXV, fig. 10A-B., operculum

of Hydrobia ulve.

“horn ”’-colour, girt on the last whorl with three distinct, broad,
dark-brown bands, showing clearly within the aperture ; spirally
regularly striated, below the slight subangulation of each whorl,
the striz prominent, with a minutely “ quasi punctate” ap-
pearance, the above becoming somewhat obsolete ; covered more
or less with rather long and well-developed hairs; whorls nine,
the apical three exceedingly minute, white and sculptureless,
the next five slightly subangulate a little above the middle,
cylindrically turreted, last whorl rather tumidly convex, about
the same length as the spire; aperture rather small, vertically
ovate, peristome acute, columella thickened, dark violet coloured,
inflected obliquely, at base sharply angulate. Operculum as
above described ; it seems to me slightly convex.

A very distinct and well-marked form, perhaps specifically

any of the forms so well represented by Mr. H. F. Blanford, 1. c.
It is a quite distinct form from that figured in the Con, Indica,
as recorded further on.

Quite distinct from the preceding species, as well shown by
the figures in Con. Indica. MHanley’s fig. 62, Conch. Misc.,

can, in my opinion, te no doubt of Reeve’s error as to the

The above-quoted fig. in the Conch.-Cab. is, as noted by M.
Brot, not characteristic. The last whorl is as often ornamented
with rows of small dots as it is without them ; the painting
is, however, of a different character from that of P. chilinoides.

I unhesitatingly agree with Mr. Blanford, in opposition to the
decided opinion of M. Brot, in uniting the Madras and Ceylon
forms ; the greater relative shortness of the last whorl is the
most marked character, the peculiar sculpture, as shown in the
Con. Indica, pl. 126, figs. 2-3, is seen in young specimens of
both. The keels of the apical whorls are difficult to detect
in the Ceylon form, specimens being always more or less decol-
late ; nevertheless they can be traced every now and then.

2 Ceylon ; ex c. G. Nevill, Esq.

Quite distinct from P. chilinoides, may prove to be a var.
of the preceding species, or even possibly of P. tanjoriensis.
There can be no doubt as to the error of identification in the
Con. Indica ; the last whorl is more or less ornamented with
flames, and the sculpture is distinct and peculiar; all of these
characters the above recorded two specimens possess; finally, it
is not in the least like P. chilinoides. Layard distinctly states his
P. levis issmooth and without ornamentation on the last whorl ;
he further considers it donbtfully distinctly from P. chilinoides ;
in all of these respects the shell sent to me by my brother as
P. levis, Lay., agrees perfectly ; this latter form is figured
neither by H. F'. Blanford, nor in the Con. Indica.

The only ally, I know, of Paludomus erronea is P. nigricans,

The operculum is that of Philopotamis. Long. 103, diam. 64

I cannot separate P. skinneri, Dohrn, even as a sub-variety.

subvar. aerea.
Paludomus aereus, Reeve, P. Zool. S. 1852, Ceylon.

The following agree fairly with M. Brot’s figs., but not with
that of the Con. Indica.

1 Ceylon ; coll. H. Nevill, Esq. [as “‘ P. nodulosa, Dohrn” ].
Long. 273, diam, 245 mil.

The interior markings are “‘arrow-headed ” and very beauti-
ful. It is unlike both Brot’s and Hanley’s figures,—nearer the
latter.

var. funiculata.

Paludomus funiculatus, Reeve, Icon. 1847, Ratnapoora in Ceylon ; ? = P.

subyar. torrenticola,
Paludomus torrenticola, Dohrn, P, Zooi. S. 1858, Ceylon.
3 Ceylon ; coll. H. Nevill, Esq. [as “ P. distinguendus, rare’’].

Agree only fairly with Messrs. Brot’s and Hanley’s figures,—
a rather smaller form.

39. Paludomus [Tanalia] neritoides.

Paludomus neritoides, Reeve, Icon. 1847, Ambegamoa, Ceylon.

2 Ceylon; ex c. Madras Museum.

subvar.

P. picta, var. pl. 4, fig. 3, is perhaps this form ; in any case it
is a very distinct and curious variety.

2 Ceylon; coll. H. Nevill, Esq. [28, 23}.

40. Paludomus [Tanalia] solida.
Paludomus solidus, Dohrn, P. Zool. Soc. 1857, Ceylon.
1 Ceylon; ex c. Dr. F, Stoliezka [12, 92].

Agrees exactly with M. Brot’s pl. 4, fig. 7b. It is probably
one of Mr, H. F. Blanford’s specimens from Hodlangkanda,
Kirime.

41. Paludomus [Tanalia] hanleyi.

Paludomus hanleyi, Dohrn, P. Zool. S. 1858, Ceylon, long. 18, diam. 13 mil.,
Con. Indica, 125, fig. 10.

7 Elletotta Ella and Kaloopaliana, Uluawah, Ceylon; coll. F. Layard,
Esq.

MELANIID&. 305

Agree exactly with the figure in Con, Indica, and with
original description and measurements.

var. subpicta,
2 Yatteantotte, Ceylon; coll. H ¥F. Blanford, Esq., ex c. As. Soc.,

Bengal.

var. major [? dist. sp.].

Long. 23, diam. 20 mil.
4 Ceylon ; coll. H. Nevill, Esq. [as “ P. ? Hanleyi”}.

The preceding two forms do noi agree well together, nor with
any figure in the Conch.-Cab. or Con. Indica. The very broad
and excavate columella, faintly stained with light brown, is a
good characteristic of all the group.

42, Paludomus [Tanalia] stomatodon.

Paludomus stomatodon, Benson, Ann. Mag. 1862, Travancore; sect. Stoma-
todon.

20 Travancore, at 1,000 to 5,000 ft.; coll. Rev. S. B. Fairbank.

43. Paludomus [Tanalia P], n. sp. |

1 Khasi Hills ; coll. Colonel H. H. Godwin-Austen.
Long. 18, diam. 15 mil.

Unfortunately, does not possess its operculum. There is
nothing like it in Mr. H. F. Blanford’s collection, nor can I

find any figure at all approaching it.

44 Paludomus [Tanalia] violacea.

Paludomus violaceus, Layard, Ann. Mag. 1855, long. 6, diam. 5 lines ;
“between Gillymalle and Pallabaddoola, near Adam’s Peak ;” Con.
Indica, pl. 122, fig. 1; not Philopotamis violacea, Brot [= Phil.
ventricosula Nev. }.

3 Ceylon; coll. H. Nevill, Esq. [as “ P. violacea”’].

The opercula are those of a true Tanalia; I do not think
there can be any doubt whatever that this is the true 7. violacea.
The specimens were collected by my brother in the original
locality.

var. Similis.
Paludomus similis, Layard, Ann. Mag. 1855, p. 138, near Ratnapoora.

A rather larger, smoother, and lighter-coloured variety, agree
ing in all essential characters, those of the columella, &c.

1 Ceylon; coll. H. Nevill, Esq. [as “ P. similis, Lay.”’].
From the original locality, I believe.
