Face, neck, hands, and feet black ; fur all over the body and 

 limbs jet-black ; callosities bright flesh-colour. 



In the skull the maxillary bones are developed into strong 

 lateral ridges corresponding in structure to those of the most 

 typical Baboons. 



Distribution. This species is found far away from the habitat 

 of the true Baboons, whose home is in the Ethiopian Region. 

 The Black Baboon is an inhabitant of Celebes, one of the islands 

 of the eastern portion of the Malay Archipelago. It is found, 

 however, also in the neighbouring island of Batchian, further to 

 the east indeed the most easterly range of the Quadrumana 

 as well as in some of the Philippine Islands to the west. In both 

 of these regions it is supposed to have been accidentally intro- 

 duced by the Malays. In Batchian, Mr. Wallace remarks, "it 

 seems so much out of place that it is difficult to imagine how it 

 could have reached the island by any natural means of dispersal, 

 and yet not have passed by the same means over the narrow 

 strait to Gilolo so that it seems more likely to have origi- 

 nated from some individuals which had escaped from confine- 

 ment, these and similar animals being often kept as pets by the 

 Malays and carried about in their praus." Analogous to the 

 distribution of this animal in the Philippines and Celebes is 

 that of a genus of Parrots Prioniturus with racquet-shaped 

 tails. The species of the latter genus are divided between 

 Celebes and its small adjacent islands and the Philippines and 

 the small islands adjacent to that archipelago, and present a 

 curious case of the restricted range of a well-marked group. 



Habits. This interesting animal, geographically so isolated, 

 lives in the luxuriant forests in small companies, and feeds 

 chiefly on the abundant fruits which these forests provide. In its
