rezas then sit squatted on the brandies with their tail hanging straight down, often 

 surrounded by swaying Usnea-lichens which hang down from the branches in long tufts, 

 they are in spite of their size very difficult to detect and often elude even the sharpest 

 eyesight. 



It is quite interesting to note that SJOSTEDT found a Mallophagan parasite on 

 these Guerezas, the first of that kind ever recorded from a monkey. It has been 

 described under the name of Trichodecte scolobi by KELLOGG (se No. 15 : 4 of this work).

These specimens agree rather closely with POCOCK'S description of the typical 

 Cercopithecus albogularis. but it differs in the following points. POCOCK describes the 

 typical albogiilun'* as follows: Head, cheeks, and dorsal area between the shoulders 

 speckled black and grey - - In all the specimens from Kilimandjaro the hairs 



of the head and nape are black and ringed with yellow. In some larger and stronger 

 specimens this yellow might be termed reddish yellow, and in all it is decidedly yellow, 

 not grey. On the hindneck the rings are paler, more whitish. Shoulders and arms 

 are wholly black in the Kilimandjaro monkeys, except that the inner side of the upper 

 arm is more or less ashy grey, but the forearm is intensely black, not speckled as in the 

 typical a1bognlnr(* according to POCOCK. The legs are black, finely speckled with ashy 

 grey. Red hairs at the root of the tail and in the ischiopubic region are found in both 

 sexes and in all ages, but less in the adult male than in the others. Chin and throat white 

 (in younger specimens with soft wavy hairs); on the sides of the neck this white area 

 passes into a broad iron grey speckled collar which, however, leaves a broad dark band 

 on the hind-neck free and with its black hairs sparingly ringed with whitish or pale yellow 

 contrasting against the iron-grey collar. The white of the throat does not extend to the 

 inside of upper arm as in the typical form according to POCOCK, and it is rather sharply 

 defined from the dark grey ventral surface. On the back the reddish yellow is quite 

 dominating on the lumbal and sacral regions and from there extending more or less 

 forward, and on the tail, flanks etc. 



These differences, although slight, appear to indicate a separate geographic race 

 or subspecies, which I name after the type-locality Kibonoto. 



This monkey is according to SJOSTEDT very common even up in the rain forest. 

 It lives in greater or smaller bands in dense forests, in groups of trees in the farms and 

 similar localities. When caught they remain wild for a long time and are difficult to 

 tame as they keep their angry disposition and are unreliable. They are caught by the 

 Wadshaggas in a kind of baskets densely made of twigs and put in traps b v icks. These 

 were placed on the ground in the farms where the monkeys lived, and made heavy by 

 stones put on them.
