246 MR. p, L. sci/ATEB ON THE [Mar. 14, 



Museum from Berlin. It is closely allied to C. melanogenys, but 

 differs in having only a very narrow black streak beneath the con- 

 spicuous white cheeks, the fur above more punctulated, and a 

 much brighter rufous tail. 



There can be no doubt that the Monkey which I described in 

 1887 from a specimen formerly living in the Society's Menagerie, 

 and referred doubtfully to C. ascanias, belonged to C. schmidti. 

 I now exhibit a coloured sketch of this individual (Plate XVI.) 

 taken by Mr. Srait in 1884. This specimen, presented by the 

 Eev. W. C. Willoughby in December 1883, was originally obtained 

 in Manyuema. It died in November 1886.

Hah. "West Africa. 



This Monkey is distinguished from all the other species of the 

 section known to me by the absence of black stripes on the face, 

 by the grey under surface, and by the peculiar shape of the white 

 nose-spot, which is narrowed above and broadened below. 



It is not uncommon in captivity, and we have had some 10 or 12 

 specimens of it during the past thirty years, but I know of no 

 anthentic record of the exact district of West Africa in which it is 

 found wild.

Hah. Pernando Po (Fraser). 



This species is quite unmistakable from its red nose (of which 

 the upper portion is sparingly covered with red hairs), reddish 

 ears, and bright ferruginous red tail. We first received a living 

 specimen of it in 1884, and another in 1885. The former lived 

 until January 1888. I exhibit its skin.
