hairs in front. The whiskersare, in adult maies at least, well deve- 

 loped, and the long hairs are banded. The head and back has the 

 hairs ringed with a colour which perhaps cornes nearest to light 

 « chamois » (Oberthur, 325.1). Thus a rather dull, almost brow- 

 nish gênerai colour is produced, not yellowish (or greenish") as in 

 the East Atrican Johnstoni (which is also represented in the Ter- 

 vueren collection) and allies, not aven on the flanks is this the 

 case. The limbs are grev speckled with whitish, hands and feet 

 are, at least in the adult, black. The tail is also speckled above, 

 almost whitish grev beneath. The chin is, of course, black; ail 

 other under parts and inside of limbs white. The différences from 

 this in Pocock's description (1. c.) may dépend upon that he had 

 voung spécimens before him. 



In other parts of Congo other forms of this group are to be 

 found. Matschie has f. i. described not less than four kinds in the 

 vear 1912 ('). 



There are still a few more spécimens of this group in the Congo 

 Muséum, which are too young to be described. It is, however, of 

 interest to note, that there is a very vellow-looking skin from 

 Inongo and another verv dark brown from Kutu, thus from places 

 which otherwise use to hâve a similar fauna. Both thèse hâve 

 rufous hairs at the anal région as well as also below the callosities.

This Tumbili monkev difters verv plainlv from the northern 

 centralis in the foUowing points. It has no definite white brow- 

 band, only some greyish whitish hairs mixed with black which 

 form â faint substitute for such one. The black hairs form espe- 

 cially a dense group above the interorbital région. The chin is not
