TERRESTRIAL MOLLUSCA INHABITING SOCIETY ISLANDS. 53 
the above author’s views in regard to Pfeifter’s P. suturalis being = strigosa. There 
is too much discrepancy in the two diagnoses to warrant their affiliation.

This, the only species of Partula inhabiting Borabora, is peculiar to and widely 
diffused throughout that island. They occur in larger numbers both on the trunks and 
foliage of trees and bushes. Notwithstanding its wide range over the island, it has not 
developed a single local variety. In fact it exhibits less variation than some of the 
species at the other islands which are restricted to single valleys. 
It may be recognized by its rather solid texture, ovate-conical form, rather short 
spire, large inflated body-whorl, small compressed perforation and white suboval 
aperture. ‘The parietal region is never toothed. The peristome is white, moderately 
expanded, not very thick, labiated within, surface rather flat and sloping. Columellar 
hp subnodose. Color whitish corneous, luteous, fulvous brown, with or without a 
brown or purple-brown apex. It is never banded. Some are more elongate than 
others, as the following measurements will show :— 
Length 20, diam. 104 mill. 
Length 16, diam. 104 mill. 
A careful comparison of /utea with Pfeiffer’s description of lilacinu has convinced 
me of the correctness of Dr. Hartman’s views in uniting the two species. I have no 
examples of the ‘lilacina” color mentioned by Pfeiffer. If the determination is 
correct, his habitat ** Marquesas ” is certainly wrong. 
Reeve’s P. solidula is decidedly distinct, and of a different type from lutea. Reeve’s 
figure closely resembles Pease’s compacta, but wants the parietal tooth of that species. 
Pfeiffer describes the peristome as “late expansum, margine dextro superne sinuato, 
tum strictusculo,” which agrees with Reeve’s figure, but not with Zutea.
