Gtbet's Wallaby. 



Form slender and delicate. General colour very similar to thac 

 of M. rufieollis, greyish fawn on the back, becoming more rufous on 

 the nape and back of head. Underfur rather thick and woolly, 

 slaty brown at its base, rufous at tip. Ears rufous behind, their 

 edges blackish. Face-markings distinct ; tip of muzzle pale grey, 

 but the fur bordering the naked rhinarium black for about half an 

 inch ; sides of muzzle with a distinct black whisker-mark from the 

 nose to the eye, sharply bordered below by the clear white cheek- 

 stripe, which involves the edges of the mouth, and passes backwards 

 under the eye nearly to the ear. An indistinct whitish hip-stripe 

 probably visible in some-specimens. Arms and hands to metacarpus, 

 legs and feet to end of metatarsus white or yellowish, then abruptly 

 turning to black on the fingers and toes. Central posterior claws 

 unusually slender and long, exceeding the pads by more than an 

 inch. BeUy pale grey, with a tinge of rufous. Tail very pale grey, 

 becoming whiter to its tip ; indistinct upper and lower crests of 

 white hair developed on its distal half. 



Shall (PI. VII. fig. 2). General form very unlike the other 

 members of this group, and more like that of those of the next, 

 Brain-case very small; facial region long and powerful (facial index 

 275, as in the large Kangaroos). Nasals short, broad, and enormously 

 expanded behind. Interorbital region very broad, the supraorbital 

 edges sharp, and becoming thickened and overhanging in old speci- 

 mens, the two sides quite parallel, without any noticeprble inter- 

 temporal constriction. Opening of infraorbital canal about 7 millim. 

 from orbit. Palate very complete, only a few small openings 

 present. 



Teeth all very small in proportion to the size of the animal. 

 Incisors (PI. IX. fig. 3) small and light. I.^ very short, small and 

 triangular, very similar to that of the members of the next group 

 of Wallabies, its edge scarcely longer than that of i.", a small ex- 

 ternal notch just behind its centre. P.* both above and below much 

 as in M. ruficollis.
