XVIII. Observations on some of the Terrestrial Mollusca of the 
West Indies. By the Rev. Lansdown Guilding, B.A. F.L.S. 
Read December 16, 1823. 
Havine for many years been diligently employed in investi- 
gating the Mollusca of the Antilles and Caribean Sea, 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.
