Leptachatina scutilus (Mighel)

Slender Leptachatina Snail (Leptachatina scutilus)

This species, described in 1845, was restricted to the Wai’anae Mountains on the island of O’ahu, Hawaiian Islands.

The type specimens appear to have been destroyed and C. Montague Cooke, while assigning some specimens to Jesse Wedgwood Mighels’ description, writes the following statement.:

It is with some hesitation that I refer shells to this species. Mighel’s description is incomplete and the types were probably lost in the fire which destroyed part of his collection as no trace can be found of this species.

My specimens are slightly larger than Mighel’s measurements and have an additional whorl. The measurements of an average specimen are: Length 7.0, diam. 2.3, alt. of ap. 2.3 mm.
