Achatinella vulpina (Férussac)

Foxy Oahu Tree Snail (Achatinella vulpina)

The Foxy Oahu Tree Snail was described in 1824.

The shells reach sizes of about 1,9 cm in height; they are glossy yellow, green, olive or chestnut, often banded with green or chestnut; the extremely color patterns were already mentioned by the species’ author.:

The colouring of this species is extremely variable; there is, however, but one prevailing idea in its manner of distribution. The columella is of a livid purple-rose in all the varieties.” [1]

This is one of the most common shells met with on Oahu, and passes through numerous slight variations, which have led to their description as distinct species.” [1]


The species was last found in 1965 along the slopes of the Pu’u ‘ohi’a (Mt. Tantalus); it is now considered extinct. [2]
