 Antilopinb Kangaeoo. 



Size large, form stout and heavy. Fur very short, coarse and 

 straight; underfur entirely absent. Muzzle with a large naked 

 rhinarium. General colour rich rufous ; head, body, and limbs all 

 oi a deep uniform red, very similar to that of many Antelopes. No 

 face-markings. Ears short, their colour behind quite the same as 

 that of the head. Chin, chest, and belly, and inner sides of limbs 

 whitish. Hands and feet rufous brown, becoming black on the 

 fingers and toes. Central hind claw very short, only projecting 

 about two thirds of an inch beyond the foot-pad ; feet rather short 

 in proportion to size of body. Tail .ooncolorous with body, be- 

 coming rather darker at the extreme tip. 



i^«maZ« smaller and less brightly coloared; the general rufous 

 tinge of the body replaced by a dull greyish fawn. 



Skull. Muzzle short and broad, the nasal chamber enormously 

 enlarged by the swelling out of its lateral walls (PI. VI. fig. 3). 

 Nasals very broad, their posterior about I5 their central width, the 

 latter going barely three times into their length. Interorbital 

 region not swollen at all, the supraorbital edges sharp and well 

 defined, and with a well-marked concavity on the forehead between 

 them. Intertemporal constriction very marked, the least transverse 

 breadth in specimen a no more than the posterior breadth of one of 

 the nasals. Opening of lacrymal canal bounded partly by maxillary. 

 Palatal foramina rather long, reaching backwards to the maxillo- 

 premaxUlary suture. Anterior palate very broad, its least breadth 

 about two thirds of the diastema, and its edges smoothly rounded 

 off', owing to the inflation of the lateral walls of the nasal chamber 

 above. Palate very complete ; only a few small foramina in palatine 

 bone. 



Teeth. Incisors much as in M. giganteus, except that aU three 

 are placed more vertically, and i.^ only has a single well-developed 

 external notch, in the position of the posterior notch of that spepies ; 

 a faint trace of the anterior notch, however, is present in the female 

 skull. P.^ large, oval. Molars as in M. giganteus. Anterior 

 cheek-teeth persistent*, at least until extreme old age. Lower 

 incisors unusually short. 



* Except, of course, the invariably deciduous p.^
