The specific centre of the type of this small white species is in the large valley of 
Faaloa, on the eastern coast of Raiatea, where it is found in great profusion on the 
foliage of bushes. From this central point it has migrated to the northward, where 
it is found, though less abundant, in an adjacent valley, associated with the typical 
P. dentifera. About two miles to the southward, on the same side of the island, in 
a large valley called Opoa, is found in large numbers the pretty variety bella (= 
globosa, Pse.), which has passed over a range of wooded hills into a large valley on 
the south coast, where it occurs in limited numbers in company with P. formosa. In 
another valley, some distance to the northward, on the west coast, we find another 
variety (= P. ventricosa, Garr.), which, though shaped like the type, in color closely 
resembles P. crassilabris, a ground species. 
The type, which is always decorticated, may be readily distinguished by its ovate- 
globose shape, uniform white color, not shining, constant prominent parietal tooth and 
subcircular aperture. Associated with the type are two varieties; one, pinky white, is 
very rare; the other, white with an orange-colored spire, is rather rare. The variety 
bella, Pse., differs none from the type, except in having the spire more or less light 
red and the body-whorl most generally with a very thin, smooth, pale yellowish horn- 
colored epidermis. The variety ventricosa, Garr., is usually a little smaller than the 
type, not decorticated, and is more variable in color, but never banded. ‘The ground 
color varies from-whitish to fulvous, rarely with a reddish spire, but more frequently 
with the apex of a purple-brown hue.

Shell imperforated or compressly umbilicated, solid, oblong-conic, somewhat shining, 
with rather smooth, irregular, incremental strive and closely set delicate spiral incised 
lines, which are more or less evanescent on the body-whorl ; color, pale straw-yellow, 
luteous, or fulvous, with or without a rosy apex; spire conical, with subplanulate 
outlines, about half the length of the shell; suture sometimes margined by a rugose 
white line; whorls 5-54, flatly convex, the last one convex or convexly rounded ; base
