especially on the upper surface, they form a distinct black crest, a smaller crest 
lieing present on the under-surface.* The tail is considerably swollen out 
proximally and somewhat incrassated, though the incrassation is hidden by the 
body hairs, which pass on to the root of the tail. 
Ear when laid forward reaching to the posterior border of the eye. They are 
covered internally and externally with short, stiff hairs. 
The eye is surrounded by a light ring of hairs. 
11 airs on the fold of the pouch and in the pouch-area, where they are scanty, 
are white. 
Hands and feet white or light grey above. Palms with six granulated 
elevations, each with a small unstriated pad. 
There is a small tuft of white, whisker-like hairs on the posterior side of the 
forc-arm just above the wrist. 
Soles of feet with three granulated elevations at the base of the toes, each 
with a small unstriated pad. The soles are hairy in the heel region and have a 
series of thick-set, strong hairs running along the outer and inner margins and 
bending over on to the under-surface, only the median part of which, so far back 
as the heel, is really naked. The median part is strongly granulated. 
Pouch opening vertically downwards, with moderately-developed lateral folds. 
Manimie eight (may be reduced to six or rarely four).

* This description of tlie tail, though considerably different from that given by Krefft, will still apply to his 
specimen, as he seems to have quite overlooked the small crest present on the under-surface.
