A REVISION OF THE COLUMBELLIDAE OF THE 

 PERSIAN GULF AND NORTH ARABIAN SEA, WITH 

 DESCRIPTION OF C. CALLIOPE, N.SP. 



Bv JAMES COSMO MELVILL, M.A., F.L.S. 



In the enumeration by Mr. Standen and myself '^' of the Gastropoda 

 collected, mostly by Mr. Frederick W. Townsend, of the Indo-European 

 Telegraph Service, in the Persian Gulf, Gulf of Oman, and northern 

 portion of the Arabian Sea, twenty-six species of Columbellidae are men- 

 tioned, of which all excepting one {Aesopus urania, M. and S.) belong to 

 the typical genus Columhella. To this paper we would refer in explanation 

 of the following notes. 



K few months ago some additional material was submitted by us, from 

 the same source, to Mr. Stephen Pace, then engaged on his exhaustive and 

 laborious Catalogue of the Columbellidae. We are very much indebted 

 to him for so kindly examining so large a quantity of specimens, and for 

 his pronouncements upon them. He pointed out at the same time one or 

 two errors which had crept into the enumeration ; as well as one important 

 omission, that of C.flavida, Lam. 



The following therefore must be taken as a revised list.
