MARINE SHELLvS FROM CEYLON

By H. B. Preston, F.Z.S. 



Of the specimens described in the present paper, many were 

 collected by the author in the years 1895 — 7 in the province of Uva, 

 Central Ceylon, while others, including all the marine species, 

 were obtained from the collection of the late Mr. Hugh Nevill. 

 when that collection was dispersed at auction some few years ago 

 in London.
