742 MR. R. I. pococK — A REVISION OF [June 18j 



Subsp. ANSORGEI, nov. 



Largei" than the form from the Benito River which I select as 

 typical for the species, and further differing in having much less 

 black upon the cheeks, the forwardly directed hairs in front of 

 the ear for the most part white instead of yellow and black, aiid 

 the hairs on the cheek adjacent to the face yellow with slightly 

 darkened tips, instead of yellow with pronounced infuscation of 

 the distal end. The whole dorsal area paler and greener, owing 

 to the fact that the yellow area on the hairs is much longer, 

 practically equalling, in in.ct, the black terminal poi-tion, instead of 

 being only about half its length as in G. tcdajyoin talapoin. The 

 ventral area a clean instead of a dirty white. 



Head and body? (wrongly labelled 900 mm., which is probably 

 a misprint for 400), tail 525 mm. 



Loc. Cambaca, in Angola {Dr. W. J. Ansorge, no. 4.4.9.1 in 

 B.M. register). 



A single typical specimen. 



I do not know whether the species described by Geoffroy as 

 Miopithecus cajnllatus (C.R. Acad. Sci. xv. p. 720, 1842 ; Diet. 

 Hist. Nat. iii. p. 309, 1845) is related to C talapoin or not. The 

 description indicates a distinct species at all events. The locality 

 was unknown. 



The PATAS-group. 

 Erytlwoceh^is Trouess. 



Large Monkeys, differing from the members of the foregoing- 

 groups in standing high upon their long slender limbs, in the pallid 

 whitish hue of the skin of the face and ears, and in the preponder- 

 ance of red in the hairs of the body and head and of white on the 

 lower limbs.

Hair on nose black and extending upwards to join the black 

 superciliary band, which generally has a few white hairs and which 

 extends laterally to the ears with a slight dorsal angulation above 

 the temple; hairs on lips and chin white in adult. Whiskers directed 

 downwards and backwards ; black close to the face, mostly greyish 

 white, but becoming gradually yellower and annvilated with black
