Tins small and well-characterized specks is restricted to the lotver portion of Pirai 
valley, on the northwest coast of Tahiti, where it is abundant on foliage. Pfeiffer’s 
“habitat in insulis Navigatorum ” (= Samoa Isles) is decidedly wrong. The type is 
peculiar to .he Society Isles. 
It is a solid, ovate-conic, chestnut-colored shell, marked by longitudinal cinereous 
strigations, and constant tuberculiform parietal tooth. The aperture is rather small, 
semi-oval, considerably contracted by the white, convex outer lip. It is never 
encircled by hands. Examples of a pale straw or fle.sh tint are not infrequent.

'I’liis fine arboreal species is restricted to a single valley, called Uparii, on the west 
coast of Kaiatea. I found it abundant in a limited area in the upper portion of the 
valley. A few stragglers occurred lower down in company with faia and Garrettii. 
Thotigh considered by some authors to be a variety of P. faba, I am, nevertheless, 
fully convinced of its specific value. When I first discovered it in 1861, I took but 
few examples, in consequence of not penetrating far enough into the valley to find its 
licadquarters. A more extended research in 1873 revealed its specific centre, and I 
took about eight hundred specimens in various stages of growth, and manv of the 
adults were in a gravid condition.
