DESCRIPTIONS OF TWO SUPPOSED NEW SPECIES OF 
CYATHOPOMA. 
By H. B. Preston, F.Z.S., etc. 
Read 3rd April, 1903, 
1. Cyarnopoma PrILer, n.sp. 
Shell dextral, trochiform, umbilicated. Whorls 5, spirally grooved 
and cross-sculptured with distinct lire. Periostracum smooth, of 
a deep rich brown colour, Suture channelled. Peristome double 
and reflexed. Umbilicus deep. Aperture almost circular. Alt. 38, 
diam. max, 8mm. 
Fic. I. Cyathopoma Peilei, n.sp. 
aes De serendibense, D.sp. 
Hab.—Yercand, Sherveroy Hills, India. 
The nearest ally to this species seems to be Cyathopoma Wynaadense, 
Blanford, from which it differs in having coarser but fewer spiral 
lines of sculpture, cross plications, a slightly more narrow umbilicus, 
and a channelled suture ; moreover, it is more trochiform in shape and 
of a much darker colour. 
I have much pleasure in associating with this species the name of 
Captain A. J. Peile, to whose kindness I am indebted for my specimens. 
2. Cyarnopoma (JERDONIA) SERENDIBENSE, D.Sp. 
Shell dextral, conoidal, moderately perforate, light brown in colour. 
Whorls 6, the last four spirally sculptured, the spirals being crossed 
at right angles by transverse plications bearing a stout bristly hair 
at each point of contact. The earlier whorls are quite smooth. 
Suture impressed. Peristome simple except where it approaches 
the columella, in which region it is reflexed. Aperture circular. 
Operculum calcareous, concave, multispiral, the central nucleus being 
situated at the bottom of a deep hollow. Alt. 3, diam. max. 2°5 mm. 
Hab.—Lower Uda Pussellawa, Ceylon. 
This species appears to be most closely allied to Cyathopoma Ceylanicum, 
Beddome, from which, however, it is easily distinguished by its very 
prominent spiral sculpture, and by its whorls being much less swollen 
than is the case in that species.
