Anoma gracilis (C. B. Adams)

Gracile Anoma Snail (Anoma gracilis 

The Gracile Anoma Snail was described in 1851, apparently based on empty shells; it seems that the species was already extinct at that time.

The species is endemic to the island of Jamaica, an exact locality, however, seems not to be known.

The shells are quite slender; they are pearl-white with a pure white keel and lip, they are coarsely striated at the end of the last whorl and bear excessively minute stirae otherwise. [1]
