This seems to be the first Haitian species of the family 

 noticed by any writer on natural history. Chemnitz gave a 

 good description in 1786, and Favanne, six years earlier, illus- 

 trated it The shell was known to them to be from "S. 

 Domingue;" but for nearly a century later it was not re- 

 discovered, and is now excessively rare. The locality is ap-
