Defunct Leptachatina Snail (Leptachatina defuncta)

The Defunct Leptachatina Snail, described in 1910, is apparently known only based on (sub)fossil shells which were found at a place named Mana, probably in the northeastern part of Hawai’i, Hawaiian Islands.

The species appears to have been rather variable, its shells reached sizes of about 0,9 cm in length. [1]
