BEDDOME ON N E W LAND-SHELLS. 443 lower portion of the penultimate whorl, double in its lower free portion, the coldmellar margin semicircular, the tooth small but plainly visible under the lens: total length * hich, 2\ times the breadth. Gudam hills, Vizagapatam, with the preceding, but very rare. This is the smallest known species of Diplommatina true ; it is quite a connecting link between Semper's genus Moussonia (Pupa problematica, Mousson) and true Diplommatina. These are the first species of Eudiplommatina discovered in Southern India; the genus does not apparently occur on our western ghats south of 14° N. lat., where its place is taken by Nicida. Large tracts of the mountainous country in the Vizagapatam and Ganjam districts are conchologically quite unexplored; and other species will no doubt be some day discovered, particularly as Nicida is not found. On the Nallay-Mallay mountains, Kurnool district, 15° N. lat., I could not detect either Diplommatina or Nicida, though Opisthostoma was discovered; these hills, however, have been only superficially searched, and Diplommatinas will I think yet be found there. DIPLOMMATINA (NICIDA) ANAMALLAYANA, n.sp. (Plate LII. figs. 5 and 6.) Shell scarcely rimate, oblong, the apex suddenly contracted, thin, whitish, shining; whorls 5, convex, the apical one small, obtuse, the second much larger, the three lower all equal in breadth (giving the shell a very oblong form), all smooth except the last, which has a very minute transverse striation, and is furnished with a basal keel; aperture circular ; peristome double, externally expanded, and reflexed : total length yL inch. Anamallays, in dense moist forests on the banks of the Perin-goonda river, 2000 feet elevation, rare. It is easily distinguished from all the other species by its very oblong form. DIPLOMMATINA (NICIDA) SUBOVATA, n. sp. (Plate LII. fig. 7.) Shell not rimate, conico-ovate, smooth, thin, shining, yellowish white, furnished with a subobsolete, very minute, oblique striation; whorls 6, convex, the penultimate the largest, the four upper ones gradually tapering, the apical one obtuse, the lowest whorl furnished with a rather prominent basal keel; aperture obliquely oblong; peristome single, not continuous round the penultimate whorl: total length T T inch. South-Canara ghats, moist forests, 1000-3000 feet elevation. Allied to Nicida nitidula, Blanf., but differing in its single peristome and more prominent basal keel. DIPLOMMATINA (NICIDA) PEDRONIS, n. sp. (Plate LII. fig. 8.) Shell subcylindrico-ovate, prominently rimate, thin, smooth, of a pale dull olive-colour; whorls 7, convex, the antepenultimate the largest, the four upper ones gradually decreasing, the seventh or |
