Dr. Abbott obtained sixteen adults, eight from Great Nicobar, and 
eight from Tillanchong. On Car Nicobar, the type locality of the 
species, he found onl}^ the very different P. faunulus. 
There is considerable individual variation in both color and size, but 
taken as a whole the series from the two islands are not distinguishable 
from each other. The variation in size is shown in the table of 
measurements below; that in color is for the most part conlined to the 
mantle. The entire head in front of ears and the back is blackish, 
onl}^ occasionally tinged with brown. Undcrparts blackish along sides 
and across throat, the lower neck usually suffused with an indefinite 
reddish brown. Middle of chest and belly light l)rown, in strong con- 
trast with sides and throat. The color of this area is essentially the 
same as that of the mantle, and like the latter very difficult to describe 
with any degree of accuracy. In none of the specimens, however, 
is it as pale as the extreme phase of the mantle. In a general way 
it may be described as an ochraceous buff', rather yellower than 
that of Ridgway (PI. v, No. 10). Along median line of belly this is 
usually tinged with drab, and at sides, just before merging into the 
black lateral area, with russet. The hairs have a conspicuous silky 
gloss in certain lights. The mantle, while generally of the same 
ground color is occasionally a very light buff or cream buff'. In these 
specimens the color is nearly uniform, but in the more usual phase the 
median and anterior portion of the mantle is strongly suffused with 
red. This suff'usion may be a dull brownish hazel, a clear cinnamon 
rufous, or both on difl'erent parts of the mantle. In such cases the 
browner tints are usually near center. Ears, membranes, feet, and 
naked portion of face uniform blackish brown in the dried specimens.
