THE SOOTT KANGAROO. 
The Nail-tailed Kangaroo, M. unguifer, first described by Mr. Gould, has a nail-like, horny 
excrescence at the end of its tail. It is smaller than the foregoing species. 
The Bridled Kangaroo, M. frenatus, is another nail-tailed species, discovered by Mr. Gould : 
its weight varies from ten to fifteen pounds. 
The Crescent-marked Kangaroo, M. auratus, is about the size of a rabbit. It inhabits the 
Swan Eiver district, Western Australia. 
The Hare-Kangaroo, M. leporoides, is a pretty little animal, about the size of the common 
hare. Its powers of leaping are very extraordinary. " While out on the plains of South Aus- 
tralia," says Mr. Gould, "I started a Hare-Kangaroo before two fleet dogs; after running to the 
distance of a quarter of a mile, it suddenly doubled and came back upon me, the dogs following 
close at its heels. I stood perfectly still, and the animal had arrived within twenty feet before it 
observed me, when, to my astonishment, instead of branching off to the right or the left, it 
bounded clear over my head, and on descending to the ground I was enabled to make a successful 
shot, by which it was procured." 
The Spe ctacled Kangaroo, Af. conspiscillatus, is distinguished from the last by its ears being 
considerably shorter, the more brilliant rusty-red coloring round the eye, and the want of a black 
patch at the base of the fore-leg ; the muzzle likewise is more obtuse. 
The Banded Hare-Kangaroo, M. fasciatus, is about the size of the common hare, and has 
very long and soft brown-gray hair. It is very shy and timid, inhabiting the thick brush of 
Western Australia. 
The M. hirsutus is about the size of the common hare. It inhabits Western ^Australia, where 
it is known to the natives by the name of Woo-rup. 
The Antilope-Kangaroo, M. antilopinus, is a large species, nearly the size of M, giganteus. 
It is characterized by being clothed with short, stiff hairs, which lie close to the skin, as in many 
of the antilope tribe. It inhabits North Australia. 
The Yellow Wallaroo or Isabelline Kangaroo, M. Isahellinus, has been described from a 
fiat and imperfect skin procured by Mr. Gould at Barrow Island. 
The Great Rock Kangaroo, M. rohustus — the Black Wallaroo of the colonists — inhabits the 
mountain ranges in the interior of New South Wales. The male and female differ in size and
