56 MAMMALIA. 



likewise, to have no cheek-pouches; their larynx is furnished with a sac. 

 The one longest known is the 



Sim. nemmus, L. Remarkable for its lively and varied colouring; body 

 and arms grey; hands, thighs and feet black; legs of a lively red; the tail 

 and a large triangular spot upon the loins, white; face orange; he has a 

 black and red collar, and tufts of yellow hairs on the sides of the head; 

 inhabits Cochin China. 



Macacus, or MACAauEs. 



All the animals of this denomination have a fifth tubercle on their last 

 molars, and callosities and cheek pouches like a Guenon. The limbs are 

 shorter and thicker than in a Semnopithecus; the muzzle more projecting, 

 and the superciliary ridge more inflated than in either the one or the other. 

 Though docile when young, they become unmanageable when old. They 

 all have a sac which communicates with the larynx under the thyroid car- 

 tilage, and which, when they cry out, becomes filled with air. 



Sim. silenus and leonina, L. (The Maned Macaque.) Black; ash-col- 

 oured mane and whitish beard which surround the head. From Ceylon. 



Some of the Macaques are distinguished by a short tail. 



M. rhesus. (The Pig-tailed Baboon.) Greyish; a fawn-coloured tinge 

 on the head and crupper, sometimes on the back; face flesh-colour; tail 

 reaching below the hamstrings. From Bengal. 



iNtrus, Cuv. 

 The Inui are mere Macaques, which have a small tubercle in lieu of a 

 tail. 



Ctnockphaltts, C.(1) 



The Dog headed-Monkeys, together with the teeth, cheek-pouches and 

 callosities of the Inuus, Cuv. , have an elongated muzzle truncated at the 

 end, in which the nostrils are piei'ced, giving it a greater resemblance to 

 that of a dog than of any other monkey; their tail varies in length. They 

 are generally large, ferocious and dangerous animals, found mostly in 

 Africa. 



C. papio, Desm. (The Guinea Baboon.) Yellow, verging more or less 

 on a brown; tufts of the cheeks fawn-coloured; face black; tail long. They 

 are found of various sizes, owing probably to the difference of age. When 

 full grown, frightful from their ferocity and brutality. From Guinea. The 



MAiraKiii.'s, 

 Of all the Monkeys, have the longest muzzle (30°); their tail is very short; 

 they are brutal and ferocious; nose as in the preceding. 



Sim. maimon and mormon, Lin. (The Mandrill.) Greyish brown, in- 



( 1 ) Cynocephalus, dog's head.
