coloured. It is thus difficult to give a description of this species 

 which holds good for ail spécimens. As a riile however, the upper 

 parts of the head behind the black brow band, which sometimes is 

 rather narrow, is red, from brickred to varions shades of « Indian 

 Chestnut red » (Oberthûr : 333, 1-4) and even « madder brown » 

 (334). The neck and back are usuallv darker, although sometimes 

 red (f. i. Indian Chestnut red 333.4 or « Mahoganv » 335), verv 

 often mixed with black or nearly black. The flanks are paler in 

 varions shades of red, or in one spécimen even brownish. The arms 

 are mostly red, f. i. brickred, or light fawn and the hands most 

 often, but not alwavs (in red spécimens), more or less blackish. 

 The hind legs are never red, but hâve a peculiar smoky brownv 

 grey (with a touch of « neutral tint ») colour, sometimes even 

 resembling « otterbrown » (354.1) or « dark fawn» (307.4). The 

 feet are sometimes blackened, in other cases not much darker than 

 the legs. The lower side is always pale, in red spécimens light buff 

 to buffish white, in others ashy grev to greyish white ('). 



This wonderful variability has to begin with compelled varions 

 authors to give several names, which now appear to hâve to be 

 withdrawn leaving Ellioti Dollm. as the oldest which with full 

 certaintv can be applied to the red Colohus of the Ituri forest. 



One spécimen from Mawambi coUected bv D' Christy jjt, 1913 

 differs, however, so much from ail others that it must be mentioned 

 separatelv. It is « madder brown » (334.4) of the darkest shade on 

 top of the head, blackish maroon on the nape and upper back, but 

 gradually becoming brighter on the lower back, almost « fawn » 

 (308.4), or somewhat darker than « dead leaf » (321). The arms are 

 « fawn » (shading from 308.4 above to 308.1 distally) and the legs 

 « brownish terra cotta •» (322, 3 and 2), but the hands as well as the 

 fect are sharply defined, jet black. The tail is fawn, somewhat 

 mixed with black above, paler below. Cheeks and throat smokv 

 grey, lower side otherwise pale buffish.
