margin; on the inner side the hairs are white: a whitish 
mark crosses the lmunches, running backwards from the 
knee, where it is most distinct. The fore legs are rather 
large, and the fore feet are also large, and armed with long 
and powerful claws; both fore and hind feet are of a brownish- 
white colour ; the latter are of moderate size. The tail is 
long, rather slender, and clothed with short adpressed hairs,— 
it is chiefly white, but suffused with yellowish above at the 
base, and a mark of the same colour may be traced (though 
not very distinct) along the whole upper surface, excepting 
about two or three inches at the apex, where the hairs are 
a trifle longer and of a dusky brown colour.

A skull of Macropus agilis now before me, os viewed from 
above, could scarcely be distinguished from one of M. Den - 
nettii; the size and proportions are nearly the same; the facial 
portion of the cranium of M. dpilis, however, is longer and a 
trifle narrower; the nasal hones are longer, broader, and less 
contracted in the middle than in if, Bennettii: viewed from 
beneath there is likewise but little difference, excepting in the 
size of the posterior palatal openings, these being very large 
in M. agilis, (i. e. nearly 9 lines in length), and small in 
M. Bennettii, where they are not more than 3 lines long. 
In the teeth of the two animals there are evident differences, 
both the molar and incisor teeth in M. agilis being larger. 
The skull is not that of an adult animal, having the fifth or 
liindennost molar tooth still in the socket; the four which are 
developed measure 1 inch 3} lines in length, whilst in
