each other, but difFer from other forms of C. ascanius, so that I 

 think thev must be regardée! as fonning a separate local race to be 

 named as above. 



The nasal spot looks often quite white, but a close exainination 

 reveals sometiines a faint maize yellovv tint on the upper half. This 

 may in some cases be stronger, and in one female spécimen the 

 upper third of the nasal spot is vellowish butï, while the other part 

 is only faintly tainted. Unlike the case in the typical ascanms, 

 there is no black, frontal band, at most in some spécimens a black 

 spot behind the eyes. The interorbital, black stripe is, however, 

 well developed and encroaches often on the nasal spot, sometimes 

 in the shape of a prominent triangle. The black lower cheek-band 

 begins (unlike in C. a. kassaicus) with a very broad patch at the 

 sides of the nasal spot, but narrows suddenly and dwindles usually 

 awav under the ears. It is only formed by the black tips of the 

 longer lower hairs of the whiskers, which hâve a subapical, yellow 

 ring and otherwise are white to the base (not greyish as in kas- 

 saicus). The hairs of the upper side of the head are banded with 

 yellow, sometimes a pale shade of yellowish bufF. Otherwise the 

 hairs of the upper side are banded with « brownish terra cotta » 

 (322,2), so that the back looks rather rufous. Upper arms and 

 thighs are like the back, lower arms almost black, only little 

 sprinkled, lower legs blackish grey, a little sprinkled with yellow, 

 hands black, feet blackish grey. The tail is on its upper side proxi- 

 mallv coloured like the back, but becomes then black to the end 

 \\ ithout any maroon-coloured middle part. On the lower side it is 

 proximally white and becomes then gradually fawn and finally 

 black at the tip. The most vivid red colour is between the black 

 and white along the line of démarcation. Sometimes the lower side 

 of the tail is blood red brown inside the black tip. Young and old 

 spécimen of both sexes show a great conformity.
