The generic position we have, after much consideration, decided 

 to assign to this very interesting small species, is merely tentative, 

 Mr. Townsend's Karachi individuals are in finer condition than 

 the Bombay types, which were collected in shell-sand, and the 

 apices were therefore fractured. Now the examination of perfect 

 specimens not only discloses an heterostrophe mamillate proto- 

 conch, but, though the facies be rissoid — a not infrequent circum- 

 stance in this family — and the outer lip thickened, with the 

 columella simple, yet the texture of the shell is much like a 

 Pyrgulina, e. g. edgarii or interstriata ; and we have no doubt a 

 step is now being taken in the right direction, even though the 

 position may very possibly again be changed.
