where there arc longer hairs, forming a bushy crest on the

Inhabits Van Diemen’s Land. 
The original of Mr. Ogilbys description of Hypstpr. 
cunicuius, contained in the museum of the Zoological 
Society, is said to have come from New South Wales, but it 
is possible there is some mistake as regards this habitat, since 
Mr. Gould, in his visit to Australia, found the species in Van 
Diemen’s Land only. That gentleman informs us, that it is 
generally distributed over the island, and prefers the open 
sandy, or stony forest land, rather than the thick and humid 
brushes. It is the largest of the Rat-Kangaroos, and in 
general colouring resembles the II. penicillatus; it is not 
only distinguished, however, by its superior size, but by its 
having a white tip to the tail. The proportions of the crania 
of the two animals differ considerably. 
The H. auriculas of the Zoological Society’s collection 
has the fur moderate os to texture, and tolerably long; the 
general tint of the animal is grey-brown, but the hairs on the 
upper parts of the body are rather broadly anuulatcd with 
dirty rusty white towards the point, and dusky at the point — 
next the skin, or at the root, they are grey: the under parts 
of the body are dirty white; the ears are clothed with very 
pale yellowish hairs internally, and more densely clothed with 
pale brown hairs externally: the feet are of a very pale brown 
colour, or might he described as brown-white : the tail is 
brown above, and brown-white beneath ; on the upper surface 
ol the apical portion the hairs are longish, averaging nearly 
three quarters of an inch, and of a brown-black hue ; these
