Cercopithecus cynosurus itimbîriensis (306) from Itimbiri; 



Cercopithecus aethiops lukonzolwae (516) from Lukonzolwa 

 at Lake Mweru. 



Cercocebus sp. [agilis group]. 



Three native skins in a bad state and received from unknown 

 localitv in French Congo (région de la Sangha), mav belong to this 

 species. 



It is more difïicult to décide anything about a yoiing spécimen 

 which is monnted (n° 305) and reported to be from Nyangwe as its 

 immature state makes a détermination uncertain. Matschie bas 

 described (') a species of this grcffip, C. fiuiiosus, from Béni. That 

 one appears, however, to be différent in several respects. It is said 

 to hâve « putty-coloured » (31 1 . 1) rings to the hairs and thèse rings 

 distributed from the head to the shoiilders, whereas the pale rings 

 of the Nyangwe spécimen rather may called a dull shade of « maize 

 vellovv » (36), and the sprinkling is continued over the greater 

 part of the back and on the fore legs down to just above the 

 blackish hands. The gênerai colour of the Nyangwe spécimen is 

 plainly more brownish than that of fumosus which is said to be 

 dark « smoke grev » (363.4). The tail is basally on the upper parts 

 dark brown, for the rest of the bodv colour. C. futnosus is said to 

 possess a « Biischel weisser Haaren » behind the ears, but nothing 

 like that is to be seen in the Nyangwe spécimen. More material of 

 adult animais must be acquired before any further décision about 

 the identity is made.

(^) Matschie has {Sitzber. Ges. Naturj. Fre:inde, Berlin, 1914) made this species the 

 type of a new genus : Cercolophocebus, and also described a new member of this from 

 « Kindu am Lualaba ». This species is characterised as having « sehr hellen Backenbart 

 und die auf den Wangen schaïf hell geringelten Haare ». It is named C. coelognathus.
