The most striking character in this species is the general deep hue 
of the fur of the upper parts of the body and neck; the colour may 
be described as sooty grey, but having moreover a brownish tint ; the 
whole upper surface and sides of the head are nearly black; on the 
sides of the body and outer side of the hind legs, at the base, a very 
faint fulvous tint is observable ; a large space on the haunch is of the. 
same deep hue as the back; the throat and chest are whitish, the 
visible portion of the hairs on these parts being white; at the base, 
or next the skin, they are of a deep grey colour, and so are those on 
the abdomen ; but here, though the hairs are tipped with white, the 
grey tint shows itself to a greater degree. The ears are thickly 
clothed with long white hairs on the inner side; externally they are 
pencilled with black and white, in about equal proportions, but at 
the base they are clothed with the same dense fur as that of the head, 
and this is black. The fore-legs, like the outer surface of the ears, 
are pencilled with black and white, the black becoming more con- 
spicuous towards the toes, which are covered with black hairs. The 
hind-legs and tarsi ‘are chiefly of a brown-white hue, but on the toes 
there is a considerable admixture of black ; the hairs which cover the 
nails and the sides of the toes are almost entirely black. The tail is 
of the same colour as the body at the base, and has the apex black ; 
the portion covered with black hairs is rather less than that clothed 
with the paler fur.

Two specimens of this species of Flying Phalanger were received 
by Mr. Gould from Port Essington. In size and proportions it ap- 
proaches most nearly to the Belidea breviceps, being considerably less 
than the Petaurus sciureus of authors ; but it is readily distinguished 
by its general pale colouring, and more especially by the pale yellow 
tint of the under parts of the body. The tail is slender as in B. bre- 
viceps, Waterh. ; the fore and hind-feet are of a pale yellowish hue in 
one specimen ; in the other the fore-feet have a pale brownish tint: a 
narrow black mark, commencing between the eyes, runs along the 
back, and extends nearly to the root of the tail ; a narrow blackish line 
surrounds the eyes, and a black ring encircles the base of the ears, but 
is interrupted under the ear, which is sparingly clothed with minute 
hairs, excepting at the base externally, where they are covered with
