On some neiv marine Gastropoda from the Southern Province of 

 Ceylon ; — by Messhs. G-. & H. Nevill. 



(With plate XIII.) 



[Received and read 5th August, 1868.] 



The seven new species described in this paper, are the first of 

 a considerable nnmber of new shells, fonnd by ourselves in Ceylon . 

 Up to the present, we have succeeded in identifying over 1,000 

 species, and are still obtaining many fresh additions, some of which 

 are very interesting forms, and of which we trust, before very long, to 

 publish as complete a list as possible. Ceylon has been much 

 neglected in this respect, as regards marine Mollusca, nothing having 

 been published about them, except the list in Sir E. Tennant's 

 admirable work which, however, only mentions some of the well- 

 known and characteristic Trincomalee species. 



Of the shells here described, two belong to the genus Oxijtioc, 

 proposed by Rafinesque in the " Journal de Physic" of 1819, for a shell 

 from the Mediterranean, 0. olivaeea ; the description is a very good 

 one. Morch in the "Journal de Conchyliologie" for 1803, Vol. XT, 

 mentions nine species as belonging to this genus, namely — 



1. 0. olivaeea, Raf., Malta. 



2. ,, Sieboldii } Krohn, Sicily.
