Callus-carrying Tree-Snail (Partula callifera)
This species was described in the year 1856.
The Callus-carrying Tree-Snail occurred in the higher parts of the Haamoa valley in the east of the island of Ra’iatea, where it formerly was found quite commonly, sitting on the foliage of the native vegetation.
The shells reached a heigth of 1,7 to 2,1 cm.
The species died out for the same reasons as all of the other extinct Polynesian tree-snail species.
