Unfortunately I have been unable to find Blanford's type-specimen 

 and the shells I have seen, purporting to represent the species, 

 have the palatal teeth much further back, so that I entertain 

 doubts as to their identity.

An examination of the type has convinced me that the late 

 W. T. Blanford was perfectly justified in his surmise, as recorded 

 under P. daghoba, that this species should be also referred to 

 Philalanka.
