the head; its hairs short throughout, uniformly dark brown. 

 Mammse 10*(?). 



SkvM (PI. XXIV. fig. 7) light and slender, muzzle long and 

 narrow. Nasals long, evenly expanding backwards. Interorbital 

 region very broad, smooth and rounded, its edges without any trace 

 of ridges or beading. Sagittal crests not at all, and lambdoid crests 

 but little developed. Palate as a whole remarkably unossified, the 

 anterior palatine foramina widely open, reaching backwards at least 

 to the level of the back of p.i, and sometimes of the back of p.'.; 

 posterior vacuities large, extending the whole length of the molars^ 

 the actual bony palate being therefore reduced to a narrow bridge 

 of bone extending across from one p.* to the other. Bullse small, 

 their substance thin and papery. Lower jaw with the coronoid 

 process strong and broad antero-posteriorly ; the greatest breadth of 

 the masseteric fossa attaining about 4"6 or 4*7 mUlim. internally. 



Teeth (PL XXV. fig. 4) on the whole short and thick. Upper U 

 short, not more than twice the height of i.^, and not projecting so 

 much forward as in Ph. jlavipes and the larger species, its posterior 

 edge nearly or quite touching i.^ ; lateral incisors flattened, subequal, 

 i.* slightly the largest. Canines short, barely surpassing a line 

 drawn from the tip of i.' to that of p.* Premolars evenly increasing 

 in size backwards ; p.** about three times the size of p\ Lower 

 incisors small, spatulate, subequal. Canines small, with a broad 

 posterior basal heel, from which the ascending line of the tooth be- 

 hind starts nearly at a right angle. Premolars long antero-pps- 

 teriorly, but low vertically, with broad posterior talons ; p.^ about 

 twice the size of p.' ; p.* intermediate in size between the two. M.^ 

 with a well-marked antero-internal secondary cusp. 



Milk-p.'* not yet known, but no doubt well developed and long 

 persistent, as in the allied species.

* Judging only from specimen b, which presents, howeTer, the curious 

 anomaly of having only 4 on one side and 5 on the other. The abnormal sup- 

 pression of a mamma being more likely than the addition of one, the usual 

 number may be put down provisionally as 10.
