Polished Leptachatina Snail (Leptachatina laevigata)

The Polished Leptachatina Snail, described in 1911, was restricted to the Mapulehu Ridge on the island of Moloka’i, Hawaiian Islands.

The shells reached heights of about 0.76 cm; the spires were either reddish brown above and yellowish corneous below or unicolored brownish corneous.

This species is now extinct like most of its congeners.
