QUADRUMANA. 55 



enabled by his conformation to imitate many of our actions, but whose 

 intelligence does not appear to be as great as is reported, not much sur- 

 passing even that of the Dog. 



There is a monkey in Borneo, hitherto known only by his skeleton, called 

 the Pongo, which so closely resembles the Ourang-Outang in the propor- 

 tions of all his parts, that we are tempted to consider him an adult if not 

 of the species of the Ourang-Outang, at least of one very nearly allied to it. 

 He is the largest monkey known, and in size is nearly equal to Man. 



The arms of the remaining Ourangs reach only to the knee. They have 

 no forehead, and the cranium retreats from the crest of the eye-brow. The 

 name of CHIMPAKSES might be exclusively applied to them. 



S. Troglodytes, L. (The Chimpanse") is covered with black or brown hair. 

 Could any reliance be placed on the accounts of travellers, this animal 

 must be equal or superior to man in stature, but no part of it hitherto seen 

 in Europe indicates this extraordinary size. It inhabits Guinea and Congo, 

 lives in troops, constructs huts of leaves and sticks, arms itself with clubs 

 and stones, and thus repulses men and elephants. Naturalists have gene- 

 rally confounded it with the Ourang-Outang. When domesticated he soon 

 learns to walk, sit, and eat like a man. We now separate the Gibbons 

 from the Ourangs. 



Hiio BATES, Illig. 



The Gibbons have the long arms of the true Ourangs, and the low fore- 

 head of the Chimpanse, along with the callous seat of the Guenons, differ- 

 ing however from the latter in having no tail or cheek-pouch. They all 

 inhabit the most remote parts of India. 



S. lar. L. (The Black Gibbon) is covered with coarse black hairs, ahd 

 has a whitish circle round his face. There are several other species. 



CERCOPITHECUS, Erxl. 



The long-tailed monkeys have a moderately prominent muzzle (of 60); 

 cheek-pouches; tail; callosities on the seat; the last of the inferior molars 

 with four tubercles like the rest. Numerous species, of every variety of 

 size and colour, abound in Africa, live in troops, and do much damage to 

 the gardens and fields under cultivation. They are easily tamed. 



Simla rubra, Gm. (The Patras.) Red fawn colour above, whitish 

 below; a black band over the eyes, sometimes surmounted with white 

 from Senegal. The 



SEMNOPITHECUS, Fred. Cuv. 



Differs from the Long-tailed Monkeys, by having an additional small 

 tubercle on the last of the inferior molares. These animals inhabit eastern 

 countries, and their long limbs and very long tail give them a very peculiar 

 appearance. Their muzzle projects very little more than that of the Gib- 

 bons, and like them, they have callosities on the seat. They appear,
