XVI. — Descriptions of Thirty-four Species of Marina 

 MoUiaca from the Persian Gulf, Gulf of Oman, and 

 Arabian Sea, collected by Mr. F. W. Toionsend. By 

 James Cosmo Melvill, M.A., D.Sc . 



[Plates IV. & V.] 



The last general descriptive paper, based upon Mr.Townsend's 

 large collections, was published in October 1912 *, and since 

 then I have only essayed a revision of the Turridas (Pleuro- 

 tomidse) f as well as the Terebridas \ of the Persian Gulf 

 region, the long continuance of the world-war having natu- 

 rally prevented much apportionment of time to this task. 



But now, with the following thirty-four additions to the 

 fauna, one feels the work is almost completed. The total 

 number enumerated cannot be very far short of two thousand, 

 and this includes, roundly speaking^ six hundred new to 

 science. Should circumstances permit, it would be ultimately 

 desirable to give a brief, up-to-date catalogue of the whole 

 series, with " addenda, emendanda, and corrigenda." 

 Doubtless several omissions have occurred, some due to 

 inadvertence, others through paucity of material or poor 

 condition of specimens.
