the base of the tail it is again white. This white band occupies the 
whole of the region between the angles of the jaw, and continues 
down the neck over the abdomen of a slightly greater width. It only 
encroaches on the sides of the body by sending an expansion into each 
axilla, which is visible laterally just behind the elbow. There is no 
lateral transverse white stripe across the front of the thigh, like that 
so strongly marked in M. brunii; and, unlike this last named species, 
the light grey, nearly white stripe above and parallel to the lip is very 
insignificant, and does not extend backwards under the eye. 
The ear is rounded, black inside and ont, with a slight white line 
_ formed by the similarly coloured roots of the there exposed hairs 
bounding the auditory meatus anteriorly. - 
The non-exposed surfaces of both the arm proper and the thigh 
: are of a pale grey. The other parts of both the fore and hind limbs 
are black. The nails of both the fore and hind limbs are short and 
Macropine. 
The peculiarity in the direction of the hair of the neck, which Page 51. 
elsewhere occurs only in Dorcopsis muelleri, Dendrolagus ursinus, and 
Dendrolagus inustus, is as strongly marked as in those species—all the 
hair covering the space bounded in front by a line running trans- 
versely across the parietal region, and behind by two lines joining in 
the middle line between the shoulders to form a right angle seven 
~ inches behind the occiput, and extending forward and outward to the 
shoulder-joint, being directed forward, whilst the general body-cover- 
ing of hair is directed normally backwards. 
The lips are nearly naked, as is the skin covering the subsym- 
j physial portion of the mandible, just behind which are four large 
’ and conspicuous glandular hair-follicles in the middle line, arranged 
in pairs to form a square (Plate [9] VIII.). A collection of glands of 
a similar nature is found on the upper eyelid, situated a little nearer 
: the inner than the outer canthus. These are shown in Miiller’s 
drawing of Dorcopsis muelleri.* A few long hairs are to be found on 
the sides of the upper lip. 
The eyelids are somewhat puffed, almost naked, with the eye- 
lashes scarcely apparent. 
The tail is peculiar in being of considerable diameter to near its 
extremity, and in being uniformly thickly covered, for all but its 
termination, with soft, not very short, black hair. The skin of the 
distal end of the tail is black, except for its terminal 14 inch, where 
it is nearly white. On the upper part of this white portion there 
are a few white hairs; elsewhere it is naked and scaly. The scales 
are also distinctly seen extending forward for a short space over the
