the total length, somewhat tapering towards the base. Colu- 

 mella slightly arcuate, shortly truncate near the base of the 

 subrhombic-semioval aperture; peristome unexpanded, acute, 

 the right margin slightly arcuate. Length 14, diam. 5, 

 aperture 4% x 2% mm. (Pfr.).

Pfeiffer's figures and description of a specimen from Ben- 

 son are reproduced. The specimens recorded from Cherra 

 Poonjee should be very closely compared with those from 

 Southern India ; they may prove separable. 



39. G. SINGHURENSIS W. Blanford. PL 10, fig. 5. 



Shell pyramidal, turrited, thin, corneous, polished, glossy, 

 smooth, slightly striatulate. Spire long-conic, the apex sub- 

 acute; suture impressed, minutely corrugated. Whorls 8, 

 convex, the last scarcely one-third the total length, rounded 

 beneath. Aperture nearly vertical, ovate-oblong; peristome 

 obtuse, whitish ; columella very deeply arcuate, obliquely trun- 

 cate in front. Length 12.5, diam. 4.4, aperture 4x2.5 mm.

" This is allied to the Nilgiri G. jerdoni Bens., but the sides 

 of the spire are less convex, the shell being more regularly 

 pyramidal, with a less obtuse apex. In some of the specimens 

 of this species collected alive, but in which the animal had 

 subsequently dried up, I found young shells. It would thus 

 appear to be viviparous. I have observed the same circum- 

 stance (the occurrence of young shells inside the old one) in 

 G. cassiaca Bs. In other species of this genus I have found 

 small round eggs with a calcareous shell, but these may be 

 hatched, before they are deposited by the parent " (Blanf.).
