BEDDOME ON N E W LAND-SHELLS. 447 very inconspicuous vertical striation; epidermis yellowish, with broad, oblique, bright chestnut, vertical bands, white beneath the epidermis; whorls 6, convex, with deep sutures, and very faint spiral lines, generally visible on the two to three lower whorls under a powerful glass ; the lowest whorl somewhat flattened below and keeled round the umbilical region, which is white and striated within, and less open than in C. malabaricum ; aperture a little oblique, oblong; peristome, when adult, double, not dilated, continuous, before maturity simple, thin, and a little interrupted at the apex, where it touches the penultimate whorl; operculum a little retracted, a little concave externally from the slight elevation of the margin of the outer shelly portion, closely multispiral, with a moderate transparent nucleus: length \ inch, greatest diameter -J-inch. Anamallay hills, 6000 feet elevation, in the evergreen woods or sholas; Pulney hills, 6000 feet elevation, a rather smaller variety. This is a glabrous species, with the same markings as malabaricum ; it, however, is very much larger and more conical, not at all depressed, less prominently striated, has a differently shaped umbilicus and a different operculum : the spiral liration is very inconspicuous; and I did not detect it till I was very carefully comparing this with ceylanicum. CYATHOPOMA (JERDONIA) OVATUM, n. sp. (Plate LII. fig. 16.) Shell umbilicated, ovate, spirally lirate, furnished with a light-, bright brownish, obliquely striated, thread-like epidermis, and a few hairs along the spiral costulations, white beneath the epidermis; spire conical, apex subacute; whorls 5, the lowest with about eleven spiral costulations continuous down to the umbilicus, the four upper lines nearest the suture less conspicuous, or subobsolete; the penultimate with three to four spiral lines, umbilicus moderately open, spirally lirate within; aperture oblique, oblong, the vertical and spiral lines clearly visible on the inside of the whorl; peristome continuous, or a little interrupted at the apex on the penultimate whorl, double, except on its inner or left margin; the outer lip expanded and reflexed on its outer margin, contracted at its base and again prominently expanded at the base of the columellar margin, the inner one white, shining, and minutely crenulated on its outer and lower margins; operculum as in C. wynadense, with a moderate transparent nucleus : length £ inch, greatest breadth ^ inch. Yellagherry hills, Salem district. The epidermis and spiral costulations are very similar to those of filocinctum and wynadense; it is, however, a smaller species, and ovate, not turbinate in form, and with a different operculum. C. filocinctum has the inner lip of the peristome furnished with large, prominent, obtuse, white crenations ; and the spiral ribs or costulations on the base of the lowest whorl are always continuous up to the umbilical region, there being no intervening smooth space. _ C. wynadense has the inner lip of the peristome smooth ; and the spiral costulations on the lowest whorl are generally interrupted by a smooth space |
