Endodonta lamellosa (Férussac)

Lamellar Disc Snail (Endodonta lamellosa)

The Lamellar Disc Snail was described in 1822, originally as coming from “Islands of the South Sea“, it was, however, endemic to Mt. Konahuanui, the highest peak of the Ko’olau Mountains on the island of O’ahu, Hawaiian Islands.

The Lamellar Disc Snail is now, like most of its congeners, extinct. [2]
