and smooth-haired species, but C. houtourlinii is long- and rough- 

 haired, which indicates existence in a much colder climate. 



Another Monkey in the Floi-ence Museum which attracted mv 

 attention was a stuffed specimen of Cercopithecus hrazzce, Milne- 

 Edwards, labelled " $ Congo, 188S," the gift of Count G. Brazza- 

 Savorgnan. Monsieur Milne-Edwards has also kindly forwarded 

 to me from Paris a flat skin of another individual of the same 

 species which I now exhibit. As no full description of this 

 remarkable Monkey has yet been publislied, the following descrip- 

 tion taken from these specimens may be useful : — 



CEECOPITHECrS BRAZZ.E. (Plate XXXIII.) 



Cercopithecus brazzce, Milne-Edwards, Eev. So. ser. 3, xii. p. 15 

 (1886) ; Scl. P. Z. S. 1893, p. 255. 



Above pale fulvous, densely annellated with black ; frontal band 

 of dense erect hairs chestuut, with slight white tips ; this is 

 bordered behind by a broad black band which extends between the 

 ears ; ears naked or nearly so ; upper part of nose and narrow 

 line above the eyes, in front of the rufous band, black ; lower nose 

 and upper lips white ; chin and throat furnished with long whit 

 hairs, which are much elongated in the middle line and form a 

 long white beard ; belly like the back, but darker ; hands and feet 

 black ; inner side of thighs, anus, and a line along the middle of the 

 thighs outside, white ; tail black, except just at the base, where it 

 is like the back. Length of body 21 inches, tail 22 inches. 



Hab. French Congo-land. 



The erect frontal band, which is very prominent, and the long 

 white beard, which is not so pointed as in C. diana and extends 

 some way down the middle of the throat, render this species of 

 Cercopithecus very remarkable. The white band which extends 

 from the anus across the haunches on each side and down the 

 outside of the thighs somewhat resembles that found in C. diana. 



There can be no doubt that C. brazzce is a close ally of C. neg- 

 lectus, and- it is even possible that the two species may be the same. 

 But on comparing the present skin of C. brazzce with the flat and 

 imperfect skin of C. neylectus in the British Museum, I find the 

 general colour of C. nec/lectus much more brownish, and the band 

 on the hind legs across the haunches yellowish instead of white. 

 The front part of the face-skin of the specimen of C. neglectus 

 having been cut away, it is impossible to say whether it ever 

 possessed the erect red frontal band of C. brazzce, but there are some 

 indications of the band left on the skin. In other respects the two 

 skins are much alike, and had they been from the same locality I 

 should have been inclined to refer them to the same species. 



I have also to announce that we have lately lost our unique living 

 specimen of Cercopithecus stairsi (P. Z. S. 1892, p. 580). I now 

 exhibit its skin, which it is proposed to transfer to the Xaticnal 

 Collection. The figure and description already given are sufficient 

 for the recognition of this remai-kable species, which, as previously
