 Hab. — India : Karachi.

14.— Columbella (Mitrella) zebra, Gray. 



Hab. — Persian (Julf : Linjah, 3 fathoms ; Mekran Coast : general. 



C. miser, Sowb., and C. elata, Rve., are apparently but forms of the 

 adove. 



15.— Columbella (Mitpella) terpsiehore, Leathes. 



Hab. — India : Bombay (A. Abercrombie). 



Sometimes confused with C. miser, Sowb. 



N.B. — C. (Mitrella) rugulosa, Sowb., had best be erased from the 

 former list. It was reported on insufficient authority, from Karachi, but 

 being a well-marked species, only known from the Galapagos Islands, there 

 but little doubt that it does not occur in Indian Seas. 



16.— Columbella (Atilia) albonodulosa, Gaskoin. 

 Hab. — IMekran Coast : Local. 



17.— Columbella (Atilia) eonspepsa, Gaskoin. 

 Hab. — Persian Gulf ; India : Karachi. 



This is synonymous with C. pitella, Sowb., from the Andaman Isles. 



Amongst the specimens in the Townsend collection from Karachi are 

 some labelled by a lapsus calami, C. compressa, Gask., a misprint for 

 cons per sa.

 tion, mostly worn, of the three recently separated species just mentioned.
