grey at the base, and has the apical portion black, with, generally, 

 three yellowish white rings. The crown of the head and the fore 

 legs are black ; the hind legs are blackish, the hairs being but ob- 

 scurely annulated. The throat is dirty ■vvhite, the belly and inner 

 side of the legs at the base are of a bro\vnish colour. The tail is black 

 above, and somewhat grizzled at the sides. At the base of the tail 

 beneath there are some deep reddish brown hairs. The naked cal- 

 losities are small. The hairs ou the fore part of the crown of the 

 head are black, annulated with brownish white, and so are those 

 on the side of the face immediately below the ear. The fur is tole- 

 rably long, and but loosely applied to the body. 



" In the smaller specimen the under parts of the body are some- 

 what paler than those in the larger, being brownish-grey. 



" I have named this species after my fellow curator Mr. Martin.

" This beautiful little species is about the šame size as the Mou- 

 stache Monkey (Cerc. cephus), andhas undoubtedly a close affinity to 

 that animal ; it may, howeYer, be distinguished by the bright rusty- 

 red hairs which cover the ears internally, its brilliant red tail, and 

 by the hairs in the region of the anus being also of a bright red. 



" The hairs on the upper parts of the body are black annulated 

 with yellow ; on the hinder part of the back the yellow assumes a 

 deep goldenhue. but, unlike the Moustache Monkey, the black pre- 

 vails over the yellow. On the sides of the body and the outer side 

 of the hinder legs, the hairs are greyish ; and on the belly and inner 

 side of the limbs, they are greyish- white. The fore legs are blackish 

 extemally ; a dark mark extends backvvards from the eye to the ear ; 

 below this, on the cheeks, there is a tuft of white hairs, beneath 

 ■vvhich the hairs are grizzled black and yellow, — in these respects 

 bearing a close resemblance to the Moustache Monkey. The face 

 is imperfect, and the feet have been removed from the slcin ; these 

 parts, therefore, cannot be described.
