MACROPUS BRACHIOTIS. 24? 



Inhabits the mountains south-east of Sydney. 



In many respects M. Jourdan's description agrees 

 with M. peniciUatm, but that is remarkable for its 

 bushy tail, a character not pointed out by M. Jourdan; 

 it moreover has a white stripe on the chest, and has 

 no white at the tip of the tail, the last character is 

 probably an accidental one. 



In Mr. Gould's collection, are specimens of a Kan- 

 garoo from Western Australia, which very nearly 

 resemble the M. penicttlatus, differing only in being 

 rather smaller, in having the tail rather less bushy, 

 the dark band on the sides of the body (which is 

 margined above with white) is more distinct, and 

 there is no white patch on the chest I doubt their 

 being specifically distinct,

Macropus brackiotis. 



Macropus (Petrogale) brachiotis, Gould. Proc. Zool. Soc. for 

 October 1840. 



This is a species from Swan River, which is closely 

 allied to the M. penicillatus, but differs in being of a 

 smaller size, in having the colouring of the fur paler, 

 the tail rather less bushy, and in wanting the black 

 flank mark ; the ears, moreover, are smaller in pro- 

 portion and less pointed. 



Fur rather short, and harsh to the touch ; general 

 tint grey, slightly washed with rusty brown the 

 latter tint is more distinct towards the sides of the 

 body ; under parts and inner side of limbs dirty yel-
