The colour of the back is black with an admixture of golden- 

 coloured hairs ; the abdomen is covered with hairs of a dark golden 

 colour, a narrow strip of flaxen hairs running longitudinally down 

 the body from the lower part of the neck, ceasing at the lower third 

 of the abdomen. The tail is black, save for its last fifth, which is 

 flaxen-coloured. The hands (vide fig. 3) are armed with moderately 

 strono- claws, and the digital interspaces are webbed to a small extent. 

 The leet (vide fig. 4) are armed with much stronger claws, and have 

 considerably deeper webs in the interspaces. The soles of the feet 

 are black, the palms of the hands of a lighter colour, and the dorsal 

 surfaces of both are clothed with short golden hairs. The scrotum 

 is large and covered with hair ; it contains the testicles, which are 

 easily to be returned to the abdomen. 



Muscular System. 

 Panniculus. — The dorsal portion extends over the entire back as 

 a thin sheet. It is especially strong and well-marked (1) over the 

 head, especially the vertex, from which it passes into the checks and 

 becomes connected with the roots of the large cheek-hairs; (2) in 

 the scapular region and over the latissimus dorsi, with which it has 

 some connections ; and (3) over the back of the thighs, where it is 

 associated in some degree with the hamstring muscles. The ventral 

 part is attached to the inner aspect of the deltoid ridge under the 

 deep portion of the pectoralis, and extends downwards from this 

 attachment over the thorax and abdomen. 



Muscles of the Head and Necl\ — By the side of that portion of the 

 panniculus which passes to the cheek there lies a slender muscle 

 which, taking origin from the bone in front of the orbit, ends in a tendon 

 which is inserted into the side of the cartilage of the nose (levator alae 

 nasi). There is a large elevator of the upper lip, separated from the 

 panniculus by the numerous and large branches of the infraorbital 

 nerve, and prolonged into the mucous membrane of the roof of the 

 mouth as far as the middle line. In front of this is a dilatator naris. 

 A small buccinator is present. Levator labii inferioris arises from 

 the ujjper surface of the inferior maxilla just posterior to the incisors 

 and descends, ex})anding considerably, to the skin below the jaw. 



Masseter consists of three parts : — (1) arises by tendon from a 

 prominent tubercle placed at the front of the lowest portion of 

 the process of bone extending downwards from the zygoma to the 

 superior maxilla and its alveolar portion. The muscular fibres 

 connected with this expand and are attached to the edge and internal 

 surface of the angle of the jaw. (2) arises from the lower margin of 

 the zygoma, and is inserted into the lower jaw from its angle to 

 aboutthe position of the roots of the incisors. (3) arises partly from
