Show 1875.] LIEUT.-COL. BEDDOME ON NEW LAND-SHELLS. 449 base of the penultimate whorl; operculum as in C. procerum &c.: height g inch, greatest breadth T\r inch. Golcondah hills, Vizagapatam district, 3000 feet elevation. Very near C. procerum, but with rather a different epidermis and more ovate, having a broader base. On the higher ranges of the Anamallays (6000 feet elevation) I collected three poor specimens of a species nearly allied to this and C. procerum, but without an umbilicus ; it is probably quite distinct. CYATHOPOMA (JERDONIA) VITREUM, n. sp. (Plate LIII. figs. 21 and 22.) Shell openly umbilicate, depresso-turbinate, or rather subdiscoidal, the spire scarcely raised, whitish, of a shining glass-like texture, without any epidermis; whorls 4, the lowest terete, not descending angulari-convex, with three spiral prominently raised costulations round the region of the periphery, and one between them and the umbilical region, the upper portion nearest the suture non-lirate, or sometimes a fifth line is there present, penultimate angulari-convex, bilirate, the two apical whorls very small; umbilical region spirally lirate within ; aperture a little oblique, subcircular; peristome single, thin; operculum double, with a very small central transparent nucleus, a little concave externally from the margins being slightly raised, outer layer less shelly than usual: greatest diameter T'T inch, height ^-y inch. Sivagherry mountains (Tinnevelly district) 1000 feet elevation. This comes nearest to C. album; but numerous specimens of all ages show no signs of any epidermis, and it is of a more depressed form, and of a glassy rather than a horny texture; the operculum is much less concave and scarcely shelly. CYATHOPOMA (JERDONIA) SETICINCTUM, n. sp. (Plate LIII. figs. 23 and 24.) Shell moderately umbilicate, turbinate, rather solid, spirally lirate, furnished with a brownish epidermis, which has a minute vertical striation, very hairy along the periphery, and slightly so about the sutures, but otherwise glabrous, white beneath the epidermis; spire conical (not convex or depressed, as in C. hirsutum) ; whorls 6, convex, sutures deep, the lowest terete, descending a little rather suddenly in front, with 12-15 continuous raised spiral costulations between the suture and the keel of the umbilical region, two of which at the region of the periphery are more raised than the others, and furnished with very long patent dark brown hairs, and between these two there are one or rarely two less prominent beardless costulations, penultimate with six to seven costulations, the upper and lower sutures slightly hairy, antepenultimate with five or six, and the whorl above it with two or three less prominent lines, the two apical whorls small and nearly smooth ; umbilicus pervious, exhibiting all the whorls, not surrounded with a hairy fringe outside (as in C hirsutum), spirally ribbed within, and there furnished with a strong raised thread-like sinuate or curved sculpture (more prominent than that in the same region of C. hirsutum) ; aperture oblique, PROC.
