their point of junction, -which is on the back of the head. 
The general tint of the animal is brown, by no means dark, 
and slightly inclining to grey-brown on the back; the sides 
of the body are of a somewhat brighter colour, being slightly 
tinted with yellowish; the whole of the under parts, as well 
as the fore legs and feet, are of a dirty yellowish white; the 
hind legs are of the same tint externally as the sides of the 
body, but paler on the inner sides ; the tarsi are of an uniform 
palish brown. The ears are rather small, and rounded at the 
tip, clothed externally with short and almost velvet-like 
black hairs; on the inner side of the ears are but few hairs, 
and these are greyish. The tail is well clothed with short 
and soft hairs, brown on the upper surface, and brown-white 
beneath; on the sides of the tail, the hairs, instead of pointing 
backwards as usual, are directed upwards; the tip of the tail 
is almost destitute of hair, (apparently worn olf by friction,) 
and exhibits the scales very distinctly. The head is of a 
pale brown colour, and the muffle is naked. 
In the large size of the premolar tooth, and in the pos¬ 
session of a distinct canine. Macropus Brunii approaches the 
Htjpsiprymnus group, in which it has been arranged by Dr. 
Muller, and the elongated form of its skull would lead one to 
compare it with the Hypsiprymnus minor , hut although the 
skull is elongated in both instances, there are many important 
differences observable in its structure when the two are com¬ 
pared. The zygomatic arch is deeper and longer than in 
H. minor , and the orbit is more advanced ; the nasal bones 
terminate in a line with the anterior boundary of the orbit, 
whilst in II. minor the root of the nasal bones is situated 
considerably in advance of the same point. Ill the structure 
of the intermaxillary bones, of the true molar teeth, (judging 
from Dr. Miillers figures) and of the auditory bullif, M. 
IJrunii is conformable with the Macropus type, and to these 
points, which separate M. Brunii from Hypsyprymnit*, we
