544 APPENDIX B 



Papio ibeanus. The baboon is common all over the plains, in troops. It digs up 

 lily bulbs, and industriously turns over stones for grubs and insects. Very 

 curious, intelligent, and bestial. 



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 cannot 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 wide-spread 

 types. Some of the bats were different from any yet obtained; the same 

 may be true of the shrews. The small carnivores, and hyenas 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 Nyctmomus, 

 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' eggs, 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 

 was doing. It seemed unlikely that he could be feeding ; and the cur- 

 rent was too swift to allow him to rest ; all other hippos at that time 

 were for the most part lying in the shallows or were back among the 

 papyrus beds.
