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 

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

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

 parently the mountains of the southwestern peninsula of 

 Haiti, the single specimen found by Weinland having prob- 

 ably been washed down in a stream.
