Hah. India : Darjeeling, Siklcim ( 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 cohnnella, the flattened whorls^ 

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

 be separated also from Curvella mun'qmrensis by the more flattened 

 whorls and the more twisted columella.
