— Vaianai Valley, Island of Moorea (Andrew Garrett, Esq.).

In one hundred and forty-six species and varieties of Partula represented in my collection, this shell possesses constant and well-marked specific characters.

The surface of the shell resembles P. spadicea and varieties from Moorea in possessing the thickly crowded waved spiral striae.
