78 TEEltESTIUAL MOLLTISCA INHABITING! SOCIETY ISLANDS. 
In ,l,a,x. they vary from abbreviale-ovate to ohlong-ovate, no. solid ronghly 
striated' spire usually half the length of the shell, sometime., shorter, and the base 
more or less eompressl, umbilicated. The aperture is rather large, srthoval, edentate, 
and the eolumella is depressed, not nodulous. Sometimes the hout of the bod^ mri 
is faintly angulated. The outer lip is rather thin, moderately expanded, slant, n„, 
concave, more or less stained with purple-brown, sometimes du l whitish or tawny, 
and the inner margin, which is not very heavily labiated, is in adults .slightly sinuous 
The color varies from light chestnut-brown to dark chestnut, sometimes fulvous. 
Examples with a more or less broad, median, yellowish corneous band are not infre- 
quent in botli the Vaiau and Hapai shells. 
Tlie following hvo varieties occur in the typical hujulria only : 
Uniform whitish horn-color, with pure white lip. Rather raie. 
'i'ellowish liorn-color, with a median, narrow, reddish chestnut band. Rare. 
My largest ^’aiau specimens are 20^ mill, long, and 11 mill, in diameter. Ihe 
smallest adult from Hapai is 1 6 by 8 mill. 
I have found hybrids between Uguhris and imperforato, the latter a strictly 
arboreal species. 
Dr. Hartman, overlooking the fact that luguhris, ovalis, 2>^ote(i and fiiaca inhabit 
widely separated valleys, has suggested that the three former may be the juvenile and 
adolescent forms of the adult //wcf*. The habitats of the Uvo former species are about 
two miles apart, and five miles south of the location of fnsca. P. protea^ which = 
/iiaca, is confined to the opposite side of the island, and is separated from the latter by 
an almo.st inaccessible mountain. 
1 cannot conceive how Carpenter could have referred Pease’s ovalis to Pfeiffer’s denti- 
fera, a shell of an entirely different type. He also says, in a foot-note to the former 
author’s diagnosis of hignhris: “ This species is regarded by Mr. Cuming as probably 
a variety of P. pacijica, Pfr.,” which latter is by Dr. Hartman referred to P. Otaheitana.
