Several spécimens chiefl)^ from the district of Lake Leopold II 

 in the Congo Muséum indicate that this région is the chief habitat 

 of the species. 



In addition to thèse normally coloured spécimens there is also 

 kept in the same muséum the type of Sclater's « C. contiens •», a 

 partly albinistic spécimen (n° 754), and another still more albinislic 

 spécimen (n" 2289) received from the Zoological Garden of Ant- 

 vverp.

Spécimens from Go in Bas-Uele are hardly différent from those 

 from différent places in the Ituri farest. A voung spécimen which 

 Pilette has brought from Ponthierville is perhaps a little more 

 greyish on the sides of the neck, but hardlv so much that any dif- 

 férence can be based on this. It will thus appear, as if the distribu- 

 tion of this monkey extends to the places mentioned in a western 

 direction.

Sanga (Weyns), n° 108. 



This name is based on a quite voung spécimen and thus imper- 

 fectly known, although it certainly much differs from the fore- 

 going by the grey colour of the long hairs on the sides of the neck 

 and the vellowish brown shade on the outer side of the hind legs.
