366 QUADRUMANA. 



The fur is coarse, harsh to the touch, long, and of a black colour, 

 moderately glossy ; that on the fore-arms is reverted. On various parts 

 grey hairs are intermixed with the black, and prevail especially on the 

 lower part of the back, the haunches, and thighs ; and, being equal in 

 number, on the lower part of the back, to the black hairs, produce there a 

 grizzled appearance. The cheeks are furnished with thinly set grey hairs, 

 with black intermixed ; the ears are large and naked ; there are decided 

 ischiatic callosities (in their greatest breadth about two inches and a half), 

 a fact which most naturalists have overlooked, or denied. M. Isidore 

 Geoffrey, however, in his interesting paper on the genus Eriodes (in Mem. 

 du Mus. d'Hist. Nat. 1828), points out their existence; and the correct- 

 ness of his observation is verified by the specimen in question. 



The length of the head and body is two feet six inches. 



The hand (fig. 255), which is preserved entire, in spirits of wine,

measures, in length, nine inches and a half; its breadth across the palm is 

 three inches and four lines ; the thumb is one inch and ten lines ; the 

 middle finger three inches and six lines. 



The total height of the animal, in the erect attitude, is about four feet. 



The following description was taken from a living specimen (very 

 young), which died in 1826, in the Menagerie of the Zoological Society. 



General figure short and stout ; chest broad ; shoulders square ; abdo- 

 men protuberant ; forehead retreating behind the supra-orbital ridge, the 

 cranium otherwise well developed; nose flat; nostrils divided by a very 

 thin septum ; lips extremely mobile, and traversed by vertical wrinkles ; 

 ears large and naked ; eyes lively, deep set, and chestnut-coloured ; neck 

 short; arms slender, but muscular, and reaching, when the animal stands 

 as erect as possible, just below the knee; all the four hands well de- 

 veloped, and with opposable thumbs ; the nails human-like ; the hair mo- 

 derately coarse and straight, longest and fullest on the head, down the 

 back, and on the arms ; thin on the chest and abdomen ; on the fore-arm
