Etjfotts-bellied Wallaby. 



Size large ; form stout and heavy. Fur long, thick, and soft. 

 Underfur long and soft, slaty grey. General colour uniform 

 greyish brown, with an olive tinge, especially on the head and 

 rump. Face and head olive-grey ; face-markings quite obsolete, 

 except that there is a pale yellowish line along the upper lip. 

 Ears very short, their backs mostly olive-grey like the head, but 

 margined anteriorly with black. Nape and forequarters usually 

 dull grey-brown, sometimes with a tinge of rufous ; an indistinct 

 nuchal streak often present. Back and sides coarsely grizzled 

 grey and black ; a faint yellowish hip-stripe visible in some speci- 

 mens. Chin, chest, and belly yellow, orange or rufous, the anal 

 region most deeply coloured. Arms and legs grey-brown. Hands 

 ■ and feet brown. Tail very short, only about 2^ times as long as 

 the head, greyish brown like the back, above orange proximally, 

 and grej'ish white distally below. 



Skull long and lightly built ; facial index 207 to 220. Muzzle 

 broad behind, tapering rapidly forwards. Pj-emaxillae oblique; 

 incisors projecting much beyond the sub-nasal prominence ; naso- 

 premaxillary suture decidedly shorter than naso-maxillary. Nasals 

 shaped somewhat as in M. coxeni, i. e. tapering gently forwards, 

 their broadest point at the maxillo-frontal suture, and their posterior 

 edge running nearly transversely across, instead of being bowed 

 backwards into centre. Interorbital region strongly constricted, its 

 edges not forming overhanging prominences. Anterior palatal 

 foramina longer than in the allied species, about the length of m.** 



Teeth. Incisors long and slender ; i.' of medium length, the notch 

 not quite so far back as in most of the present group. P.* (PI. X. 

 fig. 12) very peculiar in shape, broad posteriorly, with a well-marked 

 postero-internal talon, and narrowing anteriorly to a point, the 

 internal ledge not continued beyond about half the length of the 

 tooth ; three or four distinct external vertical ridges. Molars 

 narrow and delicate.
