hue ; on the under side of the tail it is of a pale- 

 hrown colour, and the apical half is destitute of hairs, 

 but covered by scales, as in the rat's tail in a younger 

 animal, (agreeing in size with the Paris specimen,) 

 I find the same part tolerably well furnished with 

 stiff hairs, but in parts they are short from having 

 been worn. The ears are short, furnished within 

 with longish rusty-yellow hairs ; some hairs of the

 rather paler at the base. The head and cheeks are 

 of an uniform dark brownish-grey tint, the hairs on 

 these parts are obscurely grizzled with greyish-white ; 

 the crown of the head and occiput are of a deeper 

 hue. 



Length from nose to root of tail, 25 inches ; tail, 

 14^ inches; tarsus, to base of nails, 5 inches 2 lines; 

 nose to ear, 4 inches 2 lines; ear, 1 inch 8 lines. 

 Height of animal, when in its ordinary half erect 

 position, about 20 inches. 



I have examined several specimens of this species, 

 all from Van Diemen's Land ; the colour of the under

 it is totally devoid of the bright rust colour about the 

 sides of the body and limbs, which several Kangaroos
