APES, BABOONS AND MONKEYS. 271 



Continent in the family (Platyrhini) on account of the 

 greater width of the vertical partition between the two 

 nostrils. This classification has been generally aban- 

 doned for the one that divides the Monkeys of the Old 

 "World into the Simiidae and Ceropithecidae families, and 

 places the Marmosets with their thirty-two teeth, clawed 

 toes, and nonprehensile tails, in the family Halpalidae, 

 and all the other South American species with prehensile 

 tails and thirty-six teeth, in the family Cebidae. 



The Baboons differ from the rest of the Quadrumana in 

 disposition as well as appearance, having fierce tempers 

 and a bull dog courage, combined with strength and agil- 

 ity that enables them to meet their most powerful enemies 

 upon something like equal terms ; and it is said that even 

 in captivity they must at all times be treated as dangerous 

 animals. The Mandrill (Cynocephalus-mormon) of West 

 Africa, with its long shaggy hair, lion like appearance, . 

 and the peculiar markings on its face which accentuate 

 the grimaces which it is constantly making, is the most 

 interesting and wonderful of the Baboons. It is easily the 

 largest, most formidable, ferocious and hideous of its kind, 

 and fully justifies Dr. Hornaday's statement that "It 

 seems like an animal not of this earth, but reminds one 

 of the great beasts of the vision of St. John the Divine." 

 The Hamadryas Baboon, with long side whiskers and a 

 cape of long hair, is the handsomest representative of the 

 Dog-faced Monkeys, while the Golden Baboon has the 

 liveliest disposition, is the best tempered. 



Of all the Quadrumana, the Gorilla (Gorilla-savagei), 

 resembles Man the closest in walk and in structural for- 

 mation, but the Orang Utang(Simia)and the Chimpanzees 

 (Athropopithecus-niger and -calvus) approximate the 

 nearest to the Hominidae in intelligence and susceptibility 

 to training, both being mentally superior to the Gorilla 

 and the long-armed Gibbons (Hylobartes-lar) ; but as 

 none of the Apes are fur-bearing animals, our present in- 

 terest lies with some of the representatives of the Cero- 

 pithecidae rather than any of the members of the Simiidae 

 family. 



Generally speaking, the Black Monkey of commerce is 

 the skin of the White Thighed Colobus (Colobus-velloro- 

 sus) while is very abundant on the west coast of Africa.
