Hab. India: Darjeeling, Sikkim (W. T. Blanford). Type in 

 the British Museum. 



A specimen in the British Museum, presented by the late W. 

 T. Blanford in 1860, was labelled Bulimus sikkimensis, but differs 

 from that species in the sinuous columella, the flattened whorls r 

 and the covered umbilicus ; it is besides a larger shell. It may 

 be separated also from Curvella munipurensis by the more flattened 

 whorls and the more twisted columella.
