MACACUS. 79 



very thick throughout, but more sparse on the under parts. The tail is short, and 

 equally clad with long hairs, which form a depressed terminal tuft. 



Length of body from muzzle to root of tail 2 feet ; length of tail 3 inches. 



Inhabits Japan.

Head large and whiskered ; form robust ; tail stumpy and clad. General colour 

 of the animal brown ; whiskers greyish. 



Pace almost nude, flesh-coloured, with a flush of deep crimson around the 

 eyes, the nasal region and upper lip being brown as in Jf. arctoides. Pace rather 

 elongated. Callosities large. Hairs below the ears and behind the cheeks extremely 

 long, forming tufted whiskers of a greyish white, some of the hairs being tipped 

 with dark brown. Hair on the forehead and top of head short and of a dull 

 tawny brown ; but on the nape, over the shoulders, and upper part of trunk, this 

 colour becomes deeper, but paler on the limbs. The under surface generally is 

 a whitish grey. The fur is especially long over the shoulders and upper part of 

 the trunk. The tail is short and stumpy, but well clad, especially at its base, 

 and darker above than below. 



Length from the muzzle to root of tail 2 feet 9 inches ; length of tail (carried 

 erect) 3" 9 inches with the hair. 



Inhabits the mountains of Moupin. 



The resemblances which this monkey presents to M. arctoides are not confined 

 to the young, but can be traced in the skull of the adults.

Pace red, more brilliant around the orbits, and brownish on the nose and lips. 

 Tail stumpy and poorly clad. Pur rather brilliant brick-red. 



This form is closely allied to M. arctoides, which it resembles in its build and 

 in the proportions of its parts ; but this comparison is solely based on the young of 

 the species, as this red, stump-tailed monkey, is known only from young specimens. 



The colouring of the face is the same as in the young of M. arctoides. The 

 colour of the animal, as in the latter species, increases in depth of tint on the mesial 

 line of the dorsal surface, the hairs along that region being tipped with black. The 

 brick-red colour is especially brilliant on the flanks and on the outside of the limbs 

 and on the cheeks. The beard, throat, chest, and under parts generally, and the 

 inside of the limbs, are also brick-red. The hair on the top of the head is short and
