[The complete account of the new species described in this communication 

 appears here ; but as the name and preliminary diagnosis were published in the 

 Abstract, the new species is distinguished here by being underlined. — Editok.] 



Cercopithecus sclateri. (Text -fig. 87.) 



Ge7'Gopithecus sclateri Pocock, Abstr. P. Z. S. 1904, No. 5, p. 18, 

 March 22. 



Naked integument round orbits blackish, probably bluish when 

 living; eyelids and upper hp a dirty greyish yellow, probably 

 flesh-coloured when living. . Nose covered with a large sub- 

 triangular patch of hair, extending almost from the intei-orbital 

 line, where it is acutely angular, to the extremity of the nose, from 

 which, in the specimen described, the hair appears to have been 

 worn away ; laterally the patch is produced towards the cheeks 

 into an acutely angular point, the entire area being nearly twice 

 as wide as long ; the haii's composing it are for the most part white, 

 the extreme margin and the uppei- intei'orbital angle being tinged 

 with pale i-ed. No black suj)erciliary band, the reddish-white 

 bases of the backwai-dly inclined hairs of this i-egion forming a 

 pale supraorbital line. On each side from the corner' of the oi-bit 

 backwards across the temple runs a black band which expands 

 towards the ear, reaching with its inferior edge the middle of the 

 base of that organ ; while its upper edge, running above the ear, 

 is continued across the back of the head to meet at an obtu.se 

 angle with its fellow of the opposite side ; the area on the top of 

 the head, thus circumscribed, is covered with hairs banded alter- 

 nately yellow and black, those on the antero- lateral angles of the 

 area being longer than elsewhere. Beneath the temporal band on 

 the cheek there is a band of grizzly-yellow hairs, which extends 

 backwards beneath the ear on to the neck, and, increasing in 

 width and yellowness in front, runs downwards and forwards to 

 a point to meet the external angular extension of the nose-patch. 

 This yellowish cheek-band is bounded below by a band of black 

 hairs, which rises anteriorly upon the external area of the upj)er 

 lip between the corner of the mouth and the angle of the nose- 

 patch ; narrowing posteriorly it foi-ms a sinuous curve, ascending 

 on the middle of the cheek arid descending and becoming
