I first discovered this well-marked variety in 1871, at Fatimu, on the southwest 
coast of Raiatea, where the typical Mangerie does not occur. I took about 200 
examples from beneath dead wood and loose stones. In 1874, during a spell of heavy 
rains, I visited the same location and found the place converted into a swamp, and 
gathered nearly a thousand specimens from the trunks of trees, the rains having 
driven them from their usual shelter. At Viaau, a few miles to the northward of 
Fatimu, I found a second colony drowned out and crawling up the trunks of trees. 
Both locations are on the lowlands, near the seashore, where the type with a yellow 
base does not occur. 
It may be distinguished by its red or orange red callus; otherwise the cojoration 
is similar in the two varieties.

Helicina Maugeria, var. albinea, Pease, Proc. Zool. Soc., 1871, pp. 466, 476. 
This variety is restricted to a single valley on the east side of Tahaa (not ‘‘Raiatea,” 
as stated by Peare). It may be characterized by its more depressed form, sharper 
keel and white basal callus; otheiwise the coloration and markings are the same as 
the typical Mangerie.

This, the most abundant species, is not only generally diffused throughout the 
‘group, but is also equally as common and widely distributed throughout the Harvey 
Islands, 500 miles to the southward and westward. It is confined to the lowlands in 
close proximity to the seashore where it is gregarious beneath stones.
