Leptachatina exoptabilis Cooke

Desirable Leptachatina Snail (Leptachatina exoptabilis)

The Desirable Leptachatina Snail was described in 1911; it is known from two subfossil shells that were found at Lē’ahi (Diamond Head) in the south-eastern part of O’ahu, Hawaiian Islands.

This shells reach a height of about 0.78 cm.

The description is based on two specimens one of which is not adult and is slightly broken. it is most closely related to L. exilis Gul. from the same island. L. exoptabilis is, however, larger, with less convex outlines and is narrower in proportion to its length.” [1]
