Knudsen’s Leptachatina Snail (Leptachatina knudseni)
This species, described in 1911; was restricted to an area near the Halemanu Stream and the Waipo’o Falls in the western part of Kaua’i, Hawaiian Islands; it was found under ferns and among rotten leaves and was considered to be rather uncommon.
The shells reached heights of 0,6 cm and were corneous in color with a slight yellow tinge.
The species is now extinct like most of its congeners.
