This shell is a much wider departure from the Darjeeling form first 

 described by Benson, M. funiculatum, which is so much more tumid, shorter 

 in spire, of a dark purplish brown colour, and never has the peristome so 

 broad and thickened as in this species. 31. pauperculmn is intermediate 

 between the two. 



Pomatias Himalayatsle, Bs. 



Hab. — Toriiputu and Shengorh Peaks. 



Pomatias plettrophortts, Bs. 



Hab. — Very fine specimens were obtained at the village of Pachitah 

 (Camp 7) ; it was also got at Harmatti. Alt. 032, diam. 0'17 in. 



Pomatias grakdis, n. sp., PI. VII, Fig. 13. 



Shell dextral, perforate, turreted, rather swollen below, solid, with 

 moderately strong close costulation throughout, smooth on the penultimate 

 whorl above the aperture, very close fine ribbing behind the aperture ; covered 

 with a thin epidermis ; grey corneous or pale ochreous. Spire rapidly decreas- 

 ing to apes. Whorls 9, slightly convex, the last rounded below. Aperture 

 vertical, circular. Peristome double, thickened, reflected, continuous, slightly 

 angular at upper outer margin. Operculum thin, horny, indistinctly spiral 

 in some specimens. 



Alt. 055, diam. 0-20, diam. ap. 0'17 in. 



Hab. — Shengorh Peak, rather abundant in moss on rocks. 



Its very large size distinguishes it at once from P. liimalayance and P. 

 pleuropliorus, but it also differs in its more tumid form, the greater num- 

 ber of its whorls, its rounder aperture without the distinct small notch, and 

 in not being so strongly costulated. 



The three following species were found as far back as 1866-67, 

 while the survey of the Khasi and Garo hill-ranges was in progress. I was 

 in hopes that Mr. W. T. Blanford, who has described so many species of 

 the same genus, would have been able to publish these also, biit his hands 

 have been so full since then with the large and very important collections 

 from Abyssinia and Persia made by himself, and more recently with those 

 from Tarkand, together with the ordinary work of the Geological Survey, 

 that they have been laid aside. Of two of them years ago I prepared 

 figures, which are now introduced to complete Plate VIII, A. All three 

 are referred to Cyatliopoma — a genus which has not before been recorded 

 from this part of India. In form these eastern species assimilate with
