Cercopithecus kolbi. Found in company with the Colobus in heavy forest along 
the Kikuyu escarpment. The subspecies Hindei is found on Kenia. 
Cercopithecus pygerythrus johnsoni (Green Monkey). In the yellow thorns of the 
Sotik and Rift Valley, and along the northern Guaso Nyero. Leaves and acacia 
pods in their stomachs. Live in troops of from ten to twenty individually. 
Exceedingly active and agile. Often sit motionless on the very tops of the trees, 
when they can not be seen from below. Run well on the ground. 
Colobus caudatus (Black and White Monkey). Heavy mountain forests, Kijabe 
and Kenia, and on the Aberdares. Only foliage in the stomachs of those shot. 
Goes in small troops, each seemingly containing both males and females; not 
as agile as the other monkeys, and less wary. The natives prize their skins. 
On the Guas Ngishu the small mammals were in general identical with those 
of the Aberdares and Mount Kenia. 
In Uganda Heller shot an old male, Cercopithecus ascanius schmidti, a red- 
backed, red-tailed, white-nosed monkey; it was alone in a small grove of trees 
surrounded by elephant grass. In the same grove he shot a squirrel, Paraxerus, 
very different from the Kenia species. In Uganda there were fewer species of 
small mammals than in East Africa, in spite of the abundance of vegetation and 
water. 
In the Lado we found rats, mice, and shrews abundant, but the num¬ 
ber of species limited, and for the most part representing widespread 
types. Some of the bats were different from any yet obtained; the same 
may be true of the shrews. The small carnivores, and hyaenas also, were 
very scarce. 
North of Nimule Kermit shot another Funisciurus, while it was climb¬ 
ing a bamboo. 
At Gondokoro there were many bats in the houses, chiefly Nyctinomus, 
the swift-flying, high-flying, free-tailed bats, with a few leaf-nosed bats, 
and yellow bats. 
I wish field naturalists would observe the relation of zebras and wild 
dogs. Our observations were too limited to be decisive ; but it seemed to 
us that zebras did not share the fear felt by the other game for the dogs. 
I saw a zebra, in a herd, run toward some wild dogs, with its mouth 
open and ears back; and they got out of the way, although seemingly 
not much frightened. Loring saw a solitary zebra seemingly unmoved 
by the close neighborhood of some wild dogs. 
Once, on the Nile, while Loring and I were watching a monitor steal¬ 
ing crocodiles* we noticed a hippo in mid-stream. It was about 
ten in the morning. The hippo appeared regularly, at two or three 
minute intervals, always in the same place, breathed, and immediately 
sank. This continued for an hour. We could not make out what he
