their being occasionally seen in flocks to the circumstance of 
their food being abundant in particular spots—as on recently 
burnt land, &c. Mr. Gould is also of opinion, that the Great 
Kangaroo is not, strictly speaking, a gregarious animal. 
The ears in the Great Kangaroo are moderately large; the 
tail long and very thick, especially at the base; the fur 
moderate both as to length and texture, and the hairs of 
which it is composed are somewhat waved, giving it a slight 
woolly texture The general colour is grey-brown, darkish on 
the back, and rather pale on the sides of the body; the under 
parts of the body, and inner sides of the limbs, are whitish; 
the hairs of the fur, both on the upper and under parts of tho 
body, are brown-grey at the root; those on the back of the ear 
whitish-brown towards the point, and brown, or brown-black, 
at the point. The head is nearly of the same colour as the 
body ; but the muzzle is somewhat dusky, and the lower parts 
of the cheeks are greyish; around the angle of the mouth 
the hairs are white, and there is sometimes an indistinct 
whitish mark running back on to tho cheeks from that part; 
the chin is dusky. The ears are well clothed with white buirs 
internally ; externally grey, hut dusky towards the base. The 
prevailing hue of the fore-legs is whitish grey ; sometimes a 
dusky mark is observed on the elbow: the fore-feet are 
freckled, or finely pencilled, with black and white, and the 
toes are black. The bind legs and base of the tarsi are very 
pale, and may bo described as brown-white; the toes are 
brownish black, or black. The tail is clothed at the base 
with fur like that of the body, hut passing onwards towards 
the opposite extremity, it becomes gradually harsher and 
adpressed, and at the apex, where the hairs are black, they 
are very harsh. 
White, or brownish-white, varieties of this species (as well 
as of some others of tho genus) sometimes occur : Mr. Gray 
regards his M. alb us as one of these varieties. The posterior
