SHELLS OF CEYLON. 



By A. W. Laxgdon. 



The following list of the Marine Gastropoda of Ceylon has 

 been compiled in a great measure from parcels received from a 

 correspondent in that Island, during the years 1867-70. They 

 were, with few exceptions, procured from the Moors (Arabs) at 

 Trincomale by a gentleman long resident there, who writes, "They 

 are exclusively, so I am assured, shells found on the N.E. Coast of 

 Ceylon, at Trincomale, and a little to the N. and S. of it." For the 

 names of a great many I am indebted to the kindness and learning 

 of my friend, Mr. Geo. B. Sowerby, Junr., of Great Russell Street. 



My purpose in offering this list to the readers of the Quarterly 

 Journal of Conchology, is to supply an authenticatea habitat for 

 species that every Collector is sure to number amongst his 

 earliest acquisitions, and also to lead the way fur similar lists from 

 other localities, and thus help to extend our knowledge of the 

 distribution of the moUusca. 



The list, as will be seen on inspection, is very imperfect, 

 principally from the omission of small or unattractive species, such 

 as would not ensfasre the attention of unscientific collectors.
