nasals combined, 21.9; upper, tooth row, entire, 56.1; upper molars and 

 large premolar, 34.2; mandible, 81.6; lower molars and large premolar, 36.3. 



Specimens examined.— Three, from the type locality. 



Remarks. — Mr. Raven records the weight of this species as 22 pounds, 

 while his largest specimens of P. ursinus weighed 15 and 16 pounds. 

 Occasional specimens of ursinus are quite dark, especially when in worn 

 pelage, but no specimen in the collection, representing numerous localities 

 in North and Middle Celebes, south as far as Pinedapa, just north of Rano 

 Rano, approaches in any measure the rich glossy black of the new species, 

 which is further sharply differentiated from all specimens of ursinus by 

 the small, unmarked ears and the great relative size of the large upper 

 premolar.
