722 DR. J. MURIE ON MACACUS MAURUS. [Julie 4, 



insists on the identity of the two species, which my observations 

 support ; the early name, therefore, must stand. 

 The synonymy, then, runs thus : — 



Macacus maurus (Fr. Cuv.).

In addition to the descriptions and diagnosis already published, I 

 append the notes I made on the exterior characters &c. of the dead 

 body of the female termed M. inornatus by Dr. Gray. 



Ears black and nearly bare of hairs ; face of the same colour, and 

 bareness extending round the angle of the mouth. There is an ap- 

 preciable though faint moustache of long and sparse black hairs. 

 The hairs on tbe side of the head extend inwards in a wedge-shaped 

 manner upon the malar bone. Upon the frontal region the hair is 

 short and nearly black ; but the cheeks, temporal region, and occiput 

 have a sooty tinge. This latter tint extends over all the body and 

 limbs, being considerably lighter upon the lower side of the neck, 

 the chest, the abdomen, the inner aspect of the limbs, and also at 

 the rump. There is even a greyish intermixture at the inner side of 

 the forearm and lower leg. I may also" observe that the pubic part 

 of the abdomen and the groins are almost devoid of hair. 



A pair of callosities, each \\ inch long, obtain. The ischium on 

 either side of the tail has only slight downy hairs, and the skin is of 

 a roseate shade or flesh-coloured. 



Tris of a dark hazel hue ; and the pupil is of large size. The nose is 

 flat and by no means prominent ; and the nostrils slaut well outwards. 



Body. inches. 



Extreme length from superciliary ridge to callosities. 18

Girth of the abdomen 9^ 



Tail in length (slightly curved upwards) 1 



Tail in circumference 1 1 



Fore Limb.
