crossing the whorls at irregular intervals ; spire low, conoidal ; 

 whorls 6-7, convex, the last rounded at the periphery ; aperture 

 oblique, broadly and subovately lunate ; peristome acute, thickened 

 inside with a white callosity, columellar margin reflected at the

Hob. Western Himalayas from Kumaon to Hazara at elevations 

 of about 3000-7000 feet, and locally higher; not north of the 

 Pir Panjal in Kashmir.

 specimens. The fine decussating markings on the inner whorls 

 are variable, and appear to be obsolete on some Murree and 

 Hazara shells.

Very near B. monticola, but darker in colour, without any 

 distinct decussated sculpture, and with numerous varices, often
