XVIII. Observationa on some of the Terrestrial Mollusca of the 

 West Indies. By the Rev. Lansdoxvn Guilding, B.A. F.L.S. 



Read December 16, 1823. 



Having for many years been diligently employed in investi- 

 gating the Mollusca of the Antilles and Caribean Sea, I hope 

 at a future period to have the happiness of presenting a syste- 

 matic arrangement of them to the Linnean Society. I shall at 

 present notice a few of the terrestrial species found in this island, 

 the shells only of which are known. It will be seen that one 

 of them, from ignorance of the animal, has been referred by 

 Dr. Leach to a genus in which it cannot possibly remain. This 

 naturalist has placed it in the genus Carychium of Miiller, which 

 possesses only two tentacula.
