Wedge-shaped Tree-Snail (Partula cuneata)  

The Wedge-shaped Tree-Snail was described in 1956.  

The species was endemic to the island of Ra’iatea, Society islands, where it was restricted to the Ere’eo Valley on the west coast of the island, which it shared with five additional tree-snail species – all of them now extinct. [1][2]
