Subcylindric Leptachatina Snail (Leptachatina subcylindracea)

The Subcylindric Leptachatina Snail was described in 1911, it is known only from subfossil specimens found on the island of O’ahu, Hawaiian Islands, where it appeares to have been quite widespread. [1] 

This was a coastal respectively lowland species and thus disappeared shortly after the arrival of the first Polynesian settlers.

The species has also been reported from Kaho’olawe and Moloka’i, however, this may be an error. [1]
