Central Australia, near Lake Amadeus. Terrestrial, living amongst 
sand-hills covered with tussocks of porcupine grass {Triodia irritans). 
Our attention was drawn to the lirst specimen seen by Mr. E. C. Oowle as we 
were riding over porcupine sand-hills. It was running about in the daytime from 
tussock to tussock of grass. A second specimen was seen in the same district, but 
nut captured, and Mr. Cuwle has since informed me that he has seen the same 
animal in the James Range. 
Though we only secured the single specimen, there can be no doubt of its 
specihc distinction from other species of the genus.

The following is a more complete description of this species, of which the 
preliminary notice has already appeared. 
Size similar to that of the larger species of Phascologale. Form stout and 
strong. Fur close and soft, mainly composed of the under-fur. General colour a 
grizzled grey with a faint rufous tinge, especially on the head and back. 
Chin, ventral surface, inner sides of limbs and upper surfaces of hands and 
feet white. 
Tail rufous-coloured on rather less than its proximal half, where it is thickly 
covered with fairly-long hair. The distal half is thickly covered all round with 
long black hairs, which form a very well-marked dorsal and ventral crest.
