86 TERRESTRIAL MOLLUSCA INHABITING SOCIETY ISLANDS. 
It has usually been confounded with puapillata, a much larger species, measuring 
15 mill. in length, and a well-characterized papillary apex. ‘The shell now under 
consideration is only 12 mill. long, the same as stated in Pfeiffer’s description.

This fine large species is peculiar to Raiatea, where it inhabits moist grounds in 
the upper portions of the central valleys, both on the east and west coasts. It is not 
by any means common. 
Dr. Pfeiffer, on the authority of Mr. Cuming, gives the wrong habitat “ Tahiti.” 
It was, doubtless, collected by the latter at Raiatea, and, as was too frequently the 
case, he gave the above erroneous locality. 
It is the only species I know, inhabiting this group, which agrees closely in ali its 
specific characters with papillata as described by Dr. Pfeiffer. Mr. Pease, on the 
contrary, considered the preceding species to be the true papillata, notwithstanding 
the latter is stated to be 15 mill. in length, whilst the Huaheine shell is only 12, and 
invariably shows two and a half whorls. The papillata has two whorls only and the 
spire is conspicuously papillary; and Pfeiffer’s “ margine dextro superne curvato” 
accords better with this species than with the Huaheine shell. 
The color is reddish amber, rarely whitish or light corneous. Sometimes, though 
rarely, there is slight indication of a depression on the upper portion of the body-whorl, 
and more frequently the surface is slightly impressed transversely, a character common 
to nearly all the species inhabiting the group. They vary in shape, as the following 
measurements will show sas 
Length 18, diam. 12, height 64, spire 5 mill. 
Length 17, diam. 11, height 6, spire 6 mill. 
Length 14, diam. 8, height 5, spire 5 mill. 
All the above were adult examples.

This is the most abundant species inhabiting Tahiti and Moorea, being widely 
diffused over both islands, and found in the trunks of trees and foliage of bushes. 
It is, without doubt, Gould’s pudvrina, and agrees well with his description and
