56 TERRESTRIAL MOLLUSCA INHABITING SOCIETY ISLANDS. 
of the lip, which latter is very broad, flattened and conspicuously sinuous above. 
The columella is more or less gibbous. Color yellowish corneous, very rarely fulvous 
or fasciated. 
Had Reeve alluded to a parietal tooth in his description and figure of 7. solidula, 
I would not have hesitated to refer compacta to that species.

A rare species, found on foliage in the upper portions of the valleys in the south- 
west part of Tahiti. Like P. annectens, of Huaheine, and P. turgida, of Raiatea, it is 
gradually becoming extinct. 
It is a small species (16 mill.), corneous, sometimes with darker stripes, and more 
rarely with one or two transverse chestnut bands. ‘The aperture is always edentate.

The specific centre of this small and well-marked species is Vaioara, on the west 
coast of Raiatea, where it exists in prodigious numbers on bushes. It has spread 
north and south of its metropolis, and in the former direction has slightly overlapped 
the southern range of P. Thalia, and hybrids between the two species are quite 
common. ‘To the southward it ranges about one mile, where it extends a short 
distance up a valley which is the home of P. citrina. 
Its principal characters are its small size, contracted aperture, rounded or angu- 
lated peristome and nodulous columella, which latter is, as it were, pushed in towards 
the aperture. The parietal region is very rarely toothed. It is whitish or pale 
yellowish horn-color, rarely fulvous or light brown, and sometimes the apex is purple- 
brown. A variety with a brown base and sutural band is not infrequent.

Though widely diffused over Raiatea, it is nevertheless excessively rare. It is 
much larger, stouter and darker-colored than P. arguta, the nearest allied species. 
Like P. clara and P. annectens, it appears to be gradually becoming extinct. 
It does not inhabit * Tahiti,” as stated by Pease.
