MACROPUS ROBUSTUS. 241 



The Kangaroos of this section, I have reason to 

 believe, are confined to rocky and mountainous dis- 

 tricts, and display great activity in leaping from point 

 to point on the ledges of the rocks. Their broad 

 feet, covered with minute tubercles beneath, giving a 

 roughness to the surface, combined with the more 

 compact form of the body, and the bushy tail, are well 

 adapted to such habits. The tarsi are certainly shorter 

 than usual in the Kangaroos and more densely cloth- 

 ed with hairs beyond these characters I can perceive 

 none in which the species of the present section can 

 be distinguished from the preceding. In the struc- 

 ture of the incisor and molar teeth, and in the form 

 of the skull, they do not differ more than do the 

 various species of Halmaturus from each other, nor 

 so much as do the species of the first section. 



The Macropus robustus of Mr. Gould, which 1 

 shall proceed to describe, possesses the short, broad 

 feet, having the sole rough, as in M. penicillatus, but 

 its tail is not bushy : the hair is short and adpress- 

 ed, as in other Kangaroos, hence this species is inter- 

 mediate in its characters between the Halmaturi and 

 the Petrogales.
