Show 448 LIEUT.-COL. BEDDOME ON NEW LAND-SHELLS. [June 1, before the umbilical region is entered ; but this latter character constant, as some of m y specimens have the costulations continuous up to the umbilical region, as in filocinctum, so that it cannot, in the absence of the operculum, be looked to as a characteristic to distinguish them ; but the peristome, where the shell is adult, is a safe character. CYATHOPOMA (JERDONIA) SIVAGHERRIANUM, n. sp. (Plate LII. fig. 17.) Shell pyramidal, turreted, thin, umbilicus very small and obscure, straw-coloured, glabrous, spirally lirate, apex attenuated, obtuse ; whorls 5, convex, the two lower with five spiral lines scarcely raised, antepenultimate with 2-4 lines, aperture vertical, circular; peristome simple, thin, continuous or slightly interrupted at its apex; operculum double, with a sulcate margin, internally membranaceous, externally shelly, but only a little concave, as the margins are only slightly raised, nucleus central, transparent, moderate: length A-inch, greatest diameter -^j inch. Sivagherry mountains, 3000 feet elevation. This comes nearest to /. blanfordi, but is very much smaller. CYATHOPOMA (JERDONIA) ATROSETOSUM, n. sp. (Plate LII. figs. 18, 18 a.) Shell umbilicated, ovate to subturbinate, spirally lirate, thin, semitransparent, whitish, furnished with a deciduous brownish vertically but inconspicuously striated epidermis, subobsolete on some specimens ; spire conical; whorls 5, rounded, furnished with numerous close, rather inconspicuous spiral lines, along which are numerous, rather distant, patent or suberect long black lines; umbilicus more or less open, with a more or less prominent keel at its entrance, inconspicuously ribbed or smooth within ; aperture sub-vertical, circular; peristome single, subdouble or double, entire or with the outer margin beautifully crenated; operculum subdouble, externally white and shelly, and a little concave from the margins being raised, multispiral, with a large central transparent nucleus, internally membranaceous, convex, yellowish, shining: length -flinch, greatest diameter T'0 to -^ inch. South-Canara ghats, 3000 feet elevation; Anamallays, higher ranges. The peristome, the umbilical region, and even the shape of the shell are very variable, both in the S. Canara and Anamallay specimens. C Y A T H O P O M A ( J E R D O N I A ) E L A T U M , n.sp. (Plate LII. fig. 19.) Shell narrowly umbilicated, ovato-pyramidal, spirally lirate, epidermis brownish, furnished with distant prominent vertical striae and a fine very minute striation also present between them; spire conical, apex subacute, sutures deep ; whorls 5, rounded, furnished with numerous rather close spiral costulations, continuous down to the ribbed umbilical region ; aperture vertical, circular; peristome double, the inner one continuous, quite entire or very inconspicuously crenate, outer more or less expanded and reflexed, continuous all round except at the left apex, where it comes into contact with the |
