INDIAN MUSEUM, OFFICE OF SUPERINTENDENT OF GOVERNMENT PRINT^G, l66, DHURRUMTOLLAH STREET. HAND LIST OF MOLLUSCA IN THE INDIAN MUSEUM, CALCUTTA, BY GEOFFREY NEVILL, C.M.Z.S. PART II. GASTROPODA. ProsobrancMa-Beurobranchia (contd.). CALCUTTA : PRINTED BY ORDER OF THE TRUSTEES. 1884. PREFACE. Kit* 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 List, 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. NevilPs resignation will prevent any further Parts appearing, until a qualified person has been found to complete the work he has so well begun.

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 Bed Sea form is considerably stouter and broader than any of the other known ones, as can be seen from the above recorded measurements. 69. Eissoina japonica.

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. I 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 $ " ; that marked ? 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 LITTORINID^}.

Can, for instance, my Singapore specimens catalogued as L. pallescens var. erronea, and those as L. arbori- cola var. pJiilippiana, be the different sexes of one species ? Long. 16, diam. 9130- 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. tennis from the Philippines seems to be an allied form ? 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. 8^ 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. var. sub intermedia, nov. 10 Port Canning and False Point; coll.

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. ventricosa and compares it with his L. melanacrne and L. novae-zelandice. var. subgranosa.

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, L. nova-zelandice, 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. 51. Littorina erronea, n. sp. Littorina novse-zelandia3, Reeve, 1857, N. Zealand. 10 Balapiti, Ceylon j coll. G. Nevill, Esq. Long. 13, diam. lOf mil. I am convinced this species was never found in New Zealand. Prof. F. W. Button in 1878 records that he had never seen specimens. As to the localities of Reeve and von Frauenfeld 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. E. A. Smith describes a closely allied, but more compressed form, from the Solomon Islands, as L. melanacme, P. Linn. Soc. XII, 1876, pi. XXX, fig. 21 ; this may be the L. novce-z eland ice of Eischer from New Cale- donia ? 52. Littorina reticulata. Littorina reticulata, Anton, Verz. Conch., p. 53, Hal. ? and Philinpi, Abb. pi.

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 L. nodosa, Gray.

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 3J 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 condition 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.

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 PI. sulcatus. The fig. of PI. encausticus in the Con. Iconica is very fair, but fig. 30, a " PI. savignyi," has the last whorl less tumid than is usually the 3. Planaxis breviculus.

Prof, von Martens, Zool. Eecord for 1866, p. 182, says of this species — " Most closely allied to PI. nucleus [Bnig.] 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, dent icu I at ions within so fine as to be often almost imperceptible even with a lens.

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.

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.

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 macu- lated with brown streaks in young specimens only. Brot's pi. 19, 228 MELANIUXE. fig. 4a [M. cerea], 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. Melanin subula, Lea, P. Zool.

[vel M. andamanica, n. sp. ?]. Possibly a distinct species, though at present, I believe, it is correctly classed as a local variety of M. nevilli. 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. The majority of specimens are smallerthan type figure of H. nevilli, and have the last two whorls increasing much more rapidly in breadth, in this more resembling M.

It is 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.

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.

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 pi. 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, pi. 31, figs. 11-12,' la " Melania - indienne " from the Granges, = Melania varicosa, Troschel, in text, 1. c., not M. indica. Soul., as stated by Brot, a name I cannot find in the Voy.

Benson, I.e., " Anfractuum superiorum costulis obso. letis, ultimi et peimltimi liris trans versis «ostulis 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 pi. 13, fig. Ib, which may be the young) represent widely different forms. 15 Cachar and Sylhet [type var.] ; ex c.

This widely spread and variable form is not the Mel. episco- palis of the Con. Indica, which I have named var. binodulifera. 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 [pi. 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 " M. menkiana.

Possibly, indeed, it might also be classed as an extreme variety of M. variab'ilis ; the peculiar, " foliaceous " tubercles are very characteristic.

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. Icevis is smooth and without ornamentation on the last whorl ; he further considers it doubtfully distinctly from P. chilinoides ; in all of these respects the shell sent to me by my brother as P.

The only ally, I know, of Paludomus erronea is P. nigricans, of which Mr. H. F. Blanford considers it a smooth variety ; the above-quoted figure, however, shows the differences at a glance. The operculum is that of Philopotamis. Long. 10J, diam. 6J mil. Apparently it is not figured by M. Brot ; the nearest seems to be his pi. 6, fig. 14, " P. chilinoides, var. phasianinus." 36. Paludomus [Philopotamis] subdentata. Paludomus subdentata, H. Nevill, MS. Resembles Brot's pi. II, fig. 2 [P. nigricans]. Almost smooth, prettily longitudinally striped, " flames " only slightly flexuous ; columella very broadly excavated, alabaster white, subdentate at base ; spire truncate, two whorls only re- maining, the last one convexly swollen ; flames are discernible within the aperture.

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.

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.

The opercula are those of a true Tanalia ; I do not think there can be any doubt whatever that this is the true T. violacea.
