34 BINAR LONNBERG, MAMMALS COLLECTED BY THE SWEDISH ZOOLOGICAL EXPEDITION ETC. 
If a Guereza remains motionless, hidden among the branches, foliage or lichens in 
a high tree it may be difficult to see just as every other object under similar cireum- 
stances, even if it is coloured differently... But as soon as the Guereza moves, or if 
it is not directly hidden it is very easily seen. When I now have had a little per- 
sonal experience in this matter it is difficult for me to believe in the protective 
colouration of this animal at least in such surroundings as those in which I have 
seen it. 
When passing through the primeval forest on Kenia I saw Guerezas twice, 
once at a long distance when looking over the tops of the trees in a valley an early 
morning at sunrise, and another time at less distance, but as I was not able to 
secure any specimen I cannot say from my own experience whether it is more like 
the Kilimanjaro race than this race, or not, but OLDFIELD THomas has stated (Proc. 
Zool. Soe. London 1900, p. 174) that there is no difference between specimens from the 
western slopes of Kenia (8,000—10,000 feet altitude) and specimens from Kilimanjaro. 
Cercopithecus* kolbi Nrum. 
Pocock: Proc. Zool. Soc. 1907 p. 703. 
This is the common »Kima» of the forests of Brit. Kast Africa. I collected a 
good series of both sexes in different ages as well in the forests round Nairobi (f. i. 
at Mc Naughtons farm, and Sandback Baker’s »The Homestead») as at Escarpment 
station which appears to be the type locality of the species.* It was also observed 
in the big forest on the slopes of Kenia even at an altitude of 2,700 m. where bam- 
boo thickets are interspersed in the regular woods. It was common in a forest near 
Meru boma. One specimen of the same kind was also shot in a grove of big aca- 
cias at upper Luazomela river, but this place appears to be outside its regular haunts 
because the Kima is evidently a forest loving animal. It is, however, found as well. 
in the xerophilous forest edging to the steppe as all through the primeval forest 
up to the bamboo. It occurred usually in small bands about half a dozen or a dozen 
in number but old males were often seen single. In the forenoon they were some- 
times observed resting on a branch of some big tree, or even basking in the sun 
on a branch or on a fallen tree. As a rule, however, they occurred in the thick 
forest, and fled with great speed at the approach of the hunter, jumping from tree 
to tree. Sometimes they took refuge to a very high tree and felt safe there hiding 
behind the branches or among the foliage. 
‘ In similar cases it is just as difficult, if not more, to see a »Kima», or a »Tumbili» (conf. below) 
than a »Mbega» (= Guereza). 
“Tt has recently been proved that the proper name of this genus ought to be Lasiopyga if a strict 
priority should rule. As such a change would create great confusion I cannot for the present See eu: this ELitor’s 
proposal especially as Cercopithecus should not be rejected bat moved to Midas.
