90 TERRESTRIAL MOLLUSCA INHABITING SOCIETY ISLANDS. 
It has only occurred to my notice at the Paumotu and Society Islands, being very 
abundant at the latter group, where they are found in sheltered places above and near 
high-water mark, generally associated with Philippi: and luteus.

This, like the preceding species, lives just above high-water mark, and has the 
same extensive geographical range. 
They vary considerably in the convexity of the body-whorl, length of spire, and 
the minute longitudinal grooves on the spire are either very conspicuous or obsolete, 
and are sometimes confined to the apical whorls. The base is very rarely obliquely 
striated. ‘They are subject to considerable variation in color and fasciation. The type 
varies from bluish white to luteous, and girded with from four to six narrow chestnut 
bands on the body-whorl. 
The following color-varieties may be mentioned :— 
a. Uniform bluish white, corneous, luteous, brownish or orange-brown. 
b. Orange-brown with three chestnut bands. 
c. Orange-brown with chestnut base and spire. 
d. Olive-gray with three bluish white bands. 
There are usually three, sometimes four plaits on the parietal wall, one on the 
columella, and five to seven in the palate. 
The Marquesas Islands shells, which are generally known as JZ. zonatus (= cinctus, 
Pse., = cylindroides, Mouss.), are more cylindrical in shape, and the grooves on the 
spire are nearly or quite obsolete. Otherwise they differ none from Society Islands 
specimens.
