It inight be added that some native skins of this species from 

 French Congo hâve the ochraceous frontal band normally coloured. 



PosT-ScRiPTUM. — Since the above was alreadv printed, the 

 Congo Muséum has received a spécimen oS. Cercopithecus Brazzœ, 

 collected at Poko, in the Uele district, by Dr. Christy. This spé- 

 cimen agrées completely with those collected bv Comnv Hute- 

 RKAU with regard to the colouration of the frontal band, etc. Bv 

 this fact it is made still more probable that thèse Guenons from the 

 Uele district constitute a distinct géographie race, which thus may 

 be named Cercopithecus brazzœ uelensis. It is possible that 

 this form approaches the northeastern C. neglectus, but I hâve not 

 had the opportunity of forming myself a direct opinion about this 

 as y et. 



Cercopithecus leucampyx Carruthersi Pocock. 



Ikanga (Pilette), n° 1789; Bolovet (Pilette), n°' 1798, 1799; 

 Béni (Bonnevie), n° 3312; Masisi (Bonnevie), n° 3314; Rutshuru 

 (Pauwels), n°' 2272-2275; Moero (Christy), n°' 2796, 2806; Kilo 

 (Théi.ie), n" 1875; Mawambi (Christy), n° 1842. 



Studying this very interesting material I hâve arrived to the 

 conclusion, that under this name without doubt must be included 

 not only Schuhotzi Matschie, but also princeps Elliot. I base 

 this opinion on the fact, that from the same locality hâve been 

 obtained spécimens which display the characteristics of thèse 

 supposed subspecies. Thus there are spécimens in which the area 

 between the shoulders is just as speckled as the rest of the back 

 and not at ail darker from Béni (f. i., n" 3313), from Bolovet 

 (f. i., n° 1798) and Rutshuru, and also such in which the intersca- 

 pular area is darker than the back, almost black, but somewhat 

 speckled to greater or less extent from Moera (n° 593), Bolovet 

 (n" 1799), Rutshuru and so on. But there are also such spécimens 

 which are jet blgck between the shoulders, hardlv ticked at ail as 

 n" 1875 from Kilo, Béni and finally reaT « /rz^ce/i^- spécimens »
