Leptachatina leiahiensis Cooke

Leiahi Leptachatina Snail (Leptachatina leiahiensis)

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

This species is distinct from all the other species. The turrited blunt spire is very characteristic of this species as is also the oblique aperture. I know of no species with which it may be closely related. It is extremely rare. Less than a dozen specimens were obtained in four trips, two of which were made especially for this species. Of all the specimens collected, only two are now unbroken, and only four were intact when collected, as the shells are very delicate and easily broken in cleaning.” [1]
