Tuis is a very common animal in New South Wales, where it inhabits sterile and low stony ridges, particularly such as 
are thinly covered with serub and grasses. It appears to be almost universally dispersed over the face of the country, 
from the coast to the ranges I also obtained a single example on the borders of the Namoi, but I have never seen it in 
collections from any other of the Australian colonies, and I believe it to be confined to the southern and eastern portions 
of the continent. It is a robust little animal, and as the structure of the fore-feet and claws would lead us to infer, ob- 
tains the greater portion of its food by seratching ; shallow holes and small excavations, apparently formed for the purpose 
of procuring roots, being abundant in the districts in which it is found, It constructs a warm nest of grass in which it 
lies coiled up during the day, and which is frequently placed under the shelter of the branch of a fallen tree, or at the 
foot of some low scrubby bush. It also sometimes reposes in a seat like the Hare-Kangaroo, but never sits out on the 
open plains like that species. On being startled it runs for a short distance with remarkable rapidity; but from the 
circumstance of its invariably seeking shelter in the hollow logs, from which it is readily cut out, it falls an easy prey to 
the natives, who hunt it for food. 
Independently of its larger size, which is equal to that of a full-grown rabbit, the Rufous Jerboa-Kangaroo may be 
easily distinguished from every other species of the genus by the wiry character of its fur, the rufous hue of the back, 
and the black colouring of the hinder part of the ears. 
The food consists of various kinds of roots and grasses. 
The sexes present little difference either in size or colouring.
