lunate, columellar margin oblique until close to last whorl, where 

 it becomes vertical, slightly thickened, and reflected. 



Major diam. 7'5, rain. 5, height (from figure) 3'75 mm. 



Hah. Mairang, North Khasi Hills (Godivin-Austen).

 when touched.

Shell irnperfor;. te, subglobosely depressed, not very thin, smooth, 

 more or less polished, sometimes indistinctly closely striated, 

 translucent, pale yellowish ochraceous ; spire scarcely convex, 

 apex not prominent, suture very slightly impressed ; whorls 3|, 

 rather flattened above, the last sometimes descending a little in 

 front, rounded at periphery and beneath ; aperture oblique, 

 Innately subovate ; peristome not very thin, margins converging, 

 upper very slightly arcuate, columellar sinuate, rounded, sub- 

 vertical above. 



Major diam. 9J, min. 7, height 4J mm. 



Hab. Khasi Hills, Teria Ghat ; Lower Himalayas of Sikhirn, 

 common at Fankabari. 



Animal not examined. In one shell there is part of an epi- 

 phragm remaining. Col. Godwin-Austen has suggested .(Mol. 

 Ind. ii, p. 65) that this species belongs to Durgella. The name is 

 derived from the jumping habits of the animal.

 breadth 4." (Benson, in Latin.) 



Hab. Near Darjiling. 



Although Sikhim has been very thoroughly searched since this 

 species was named, no other specimens have been found, and
