296 MR. E. T. BENNETT’S ACCOUNT OF MACROPUS PARRYI. 
continuous with that of the belly and pouch; and on the hinder part of the haunches 
on either side (or rather on a space bounded by the base of the tail, the prymna, and 
the marsupium,) is a broad patch of light yellowish brown. In the common species the 
hair of the tail is far less bristly, longer, softer, and by no means adpressed. 
The head above is of a greyish mouse colour, more intense from the eyes forwards, 
where it becomes almost wholly of a dusky black. Bordering this darker colour below, 
on a level with the lower eyelid, a broad well-defined white band extends along the 
cheek from the posterior angle of the eye to the angle of the mouth. Below this is a 
similar but less strongly marked band of the common grey colour, which passes from 
the back and sides of the neck over the sides of the head, and is continued along the 
last-mentioned band to the angle of the mouth. The lips are grey, with an admixture 
of long black and white bristly hairs, and the latter are especially remarkable on the 
lower lip and chin. A broad whitish patch, with little of the grey mixture, occupies 
a space bounded by the edges of the lower jaw and extending to the upper part of the 
throat. The ears are mouse-coloured at the base, with a light grey patch on the vertex 
between them, grey in the middle, and dusky at their tips. Externally they are very 
thinly clothed with short scattered hairs, and internally they are almost naked, excepting 
a slight tuft of white hairs at the base of their anterior margin, and a narrow edging all 
round of short whitish hairs. This extreme thinness of the clothing of the ears renders 
visible on their inner surface, and also by transmitted light, a number of small glan- 
dular transparent pores. In the common species these organs are thickly clothed with 
hair on their outer surface, and are muca less bare internally than in the animal brought 
home by Sir Edward Parry, and there are consequently no transparent pores visible in 
them: the hairs of the margin of the ears are also, in the common species, of a dark 
brown approaching to black. 
On the limbs the hairs become gradually shorter and more rigid. The whole of the 
fore paw is black, with a slight admixture of grey on the metacarpal and carpal regions; 
and the claws also are black. On the hinder feet the two large outer toes are deep 
black, and covered with long rigid hairs as far as the base of the strong black hoof-like 
claws. The two small united toes are light grey, like the metatarsus and tarsus. 
The comparative extent of the naked muzzle appears in this group, as in various 
tribes of Ruminants, to afford an excellent guide in the discrimination of species, and 
perhaps also of sections, without attaining, as in some other cases, a value of generic 
importance. In the species under consideration it occupies the whole space between 
the nostrils, and downwards to the fissure of the upper lip, spreading over the flattened 
extremity of the nose, and giving off on either side a rather broad margin to the upper 
edge of each nostril. It is covered with rather large and conspicuous papille. In this 
respect the animal is allied to the Bush Kangaroo, Macr. Ualabatus, Less.; and differs 
altogether from the common Kangaroo, in which the naked muzzle is limited to a narrow 
margin surrounding each of the nostrils, with a very slight band of connexion in front.
