The Bajadebe Helix. Shell umbilicated, sinistral, snb- 

 globose, tliiji, rather swollen, conspicuously very 

 closely plicately wrinkled, wrinkles fading away on 

 the under part of the shell, fulvous, light red towards 

 the apex, whitish underneath ; whorls four to five, 

 flatly convex, last whorl angled in the middle, slightly 

 keeled ; umbilicus narrow, deep ; aperture nearly cir- 

 cular; lip simple, columellar margin much dilated 

 around the umbilicus.

Eab. Bengal. 



A delicate slightly swollen reversed shell, thickly

 striated, fulvous-olive ; spire but little raised ; wliorU 

 four to five, rather flattened, last whorl slightly

 Helix nimalayana, Benson. 



Hob. Himalaya mountains. 



Of the same typical form and sculpture as the preceding 

 species, from which it mainly difl°er3 in being much less 



prominently wrinkled, of a uniform fulvous-olive colour, 

 encircled at the periphery with a narrow chestnut band.

 with fine spiral and oblique stria, yolk-coloared ;
