These letters are used in two different columns to express partly the distribu- 
tion of the species with subspecies or closely allied forms, and partly that of the 
genus or subgenus. It is clear that such an attempt to denote the geographical 
distribution of some animals with some letters must be only approximate partly be- 
cause the distribution of the animals is irregular and partly because our knowledge 
in this matter still is very incomplete. I think, however, that this method in spite 
of its deficiency may facilitate a general survey of the matter. 
In the first table (p. 7) those 33 mammals are enumerated which have been 
found in cultivated land. These are of comparatively little interest from a zoogeo- 
graphical point of view. The greatest number of them is East African, at least as 
subspecies. Some few are widely distributed. But there are also some which extend 
into the Central Lake district of the Western forest region, viz. Crocidura fumosa, 
Genetta stuhlmanni, Dendromys insignis, Leggada triton and Lophuromus aqwilus. Al 
of these are, however, really to be regarded as more or less forest animals and they 
have also been obtained by this expedition in the forests as well (conf. table p. 20, 21). 
They have, however, remained and found suitable conditions of life even since the 
natives have cleared away the forest to give place for their shambas. In the Kikuyu 
and Meru countries the shambas as a rule are made, or have been made, on forest 
land, even if they in the present time sometimes are rather far from the forest. 
Arvicanthis pulchellus massaicus which mostly lives among bush is not a forest loving 
animal but extends westwards to Ruwenzori and perhaps beyond. The genera of 
these mammals have almost all a wide distribution only one (Zelotomys) is endemic 
and one (Tachyoryctes) chiefly northeastern. 
On steppe land about 54 different mammals have been observed or collected 
(conf. the table p. 10, 11). The exact number cannot be stated because in some instances 
it could not be ascertained to which subspecies an observed animal belonged. Some 
of these have been observed as well on the Athi plains as on the northern acacia- 
steppe south of Guaso Nyiri but as the time which could be spent at both localities 
was very short the list of small mammals especially is not complete. It might, 
however, be expected that the most common and characteristic mammals are included. 
Epomophorus wahlbergi is probably not to be regarded as a steppe mammal, although 
it was found hanging in bushes on the acacia steppe at Luazomela but a forest of 
tall acacias and other trees was not far off. On the other hand probably some of 
the small mammals from the list of those observed in the cultivated region could 
have been added. The greatest number or about 32 of these species or subspecies 
belong to East Africa in a stricter sense, but 3 of them have near relatives in the 
whole or the greater part of the Eastern Southern steppe region. Four have near 
relatives ranging to South Africa. The Buffalo for instance is very closely related 
to the typical Cape Buffalo, Saccostomus mearnsi is related to S. mashonce, Pedetes 
surdaster to P. cafer, and the Zebra to the southern zebras of the burchelli group. 
Two others have their near relatives not further south than in the Nyasa district 
(Otomys angoniensis elassodon and Sylvisorex sorelloides). Three have their relatives 
further northeast being subspecies of Abyssinian mammals (Tachyoryctes splendens
