The most important difference between the faunas of Kenia and Kilimanjaro 
is that the Bongo and the Black Forest Hog do not extend into the latter district. 
Of less importance is perhaps the absence there of Genetta stuhlmanni which, however, 
belongs to the Central Lake district. Mandinia on the other hand is lacking on 
Kenia as far as is known for the present. If the little known Cephalophus spadix 
of Kilimanjaro ist most nearly allied to the West African C. niger as TRUE has said, 
it is another hint about the affinity with the Western forest fauna. It does not 
seem impossible, however, that such an animal or a related form might be found in 
the thick forests on Kenia as well, although not yet known. 
As a summary of the discussion above may be concluded that in the district 
on the Eastern and Northeastern sides of Kenia three different faunas meet and partly 
intermingle viz. 1° the forest fauna of the mountain itself which shows several im- 
portant western affinities, 2° the fauna of the steppe country which is a typical East 
African fauna s. str., and 3° the fauna of the thornbush which north of Guaso Nyiri 
is an almost pure Somali fauna. 
There are thus three different types of faunas bound each to its own type of 
landscape (conf. above). 
In the cultivated region, which mostly has been conquered from the forest, 
remains of the forest fauna meet invaders from the bushsteppe, and in some degree — 
this is also the case in the xerophilous thin forests at the edge of the steppe. 
In the district between Guaso Nyiri river in the north, and Tana river in the 
south many members of the Somali fauna and the East-African fauna s. str. meet. 
The former which preeminently is bound to the thornbush extends with some of its 
members still further south along the strips of thornbush in some instances all the 
way to the northern side of Kilimanjaro.
