240 CLASS MAMMALIA. 



" The head, viewed in front, is pear-shaped r expanding- 

 from the chin upwards, the cranium being much the larger 

 end. The eyes are close together, of an oval form, and 

 dark brown colour. The eye-lids are fringed with lashes, 

 and the lower ones are saccular and wrinkled. The nose is 

 confluent with the face, except at the nostrils, which are 

 but little elevated : their openings are narrow and oblique. 

 The mouth is very projecting, and of a roundish mammil- 

 lary form. Its opening is large, but when closed is marked 

 by little more than a narrow seam. The lips are very nar- 

 row, and scarcely perceptible when the mouth is shut. The 

 chin projects less than the mouth; below it, a pendulous 

 membrane gives the appearance of a double chin, and swells 

 out when the animal is angry or much pleased. Each of 

 the jaws contains twelve teeth ; namely, four incisive teeth, 

 the two middle ones of the upper jaw being twice the width 

 of the lateral ; two canine, and six double teeth. The ears 

 are small, closely resembling the human ear, and have 

 their lower margins in the same line with the external an- 

 gles of the eyes. 



" The chest is wide compared with the pelvis: the belly 

 is very protuberant. The arms are long in proportion to 

 the height of the animal, their span measuring full four 

 feet seven inches and a half. The legs are short compared 

 with the arms. 



" The hands are long, compared with their width, and 

 with the human hand. The fingers are small and tapering: 

 the thumb is very short, scarcely reaching the first joint of 

 the fore finger. All the fingers have very perfect nails, of a 

 blackish colour, and oval form, and exactly terminating with 

 the extremities of the fingers. The feet are long, and re- 

 semble hands, in the palms, and in having fingers rather 

 than toes, but have heels resembling the human. The 

 great toes are very short, are set on at right angles to the 

 feet close to the heel, and are entirely without nails.
