The forests of British East Africa in which I had the opportunity of studying 

 the fauna some little time are those near Nairobi and Escarpment station, the prim- 

 eval forest on the eastern slopes of Kenia, and the woods near Meru boma. These 

 exhibit several different types, although these intergrade with each other. The forests 

 near Nairobi are more or less xerophilous with comparatively small leaves and a thin 

 foliage which admits the light to penetrate. The result of this is that a very thick 

 undergrowth of bushes and lianse is produced, and in the darkness of this several 

 animals find suitable covert. Among these are the Bushbuck, the »Suni» {Nesotragus 

 moschatus) and the Red Forest Duiker, not to mention the Bushpigs. The small 

 greenish looking Scrub Squirrel {Paraxerus jachsoni) skulks also among this under- 

 growth. The only monkey in the Nairobi forests is the »Kima» {Cereopithecus kolbi). 



The forest at Escarpment is different. It contains (or contained) in some places 

 numerous cedars, Podocarpus etc. In other places different kinds of trees, some with 

 large leaves grow at such a distance from each other that a very dense undergrowth 

 of bushes and very tall (2 — 3 m.) plants can develop and cover* the ground. The 

 Kima-monkey was common there, but a White-tailed Guereza {Colobus abyssinicus 

 kikuyuensis) inhabits also the forest chiefly on the top of the mountain plateau. A 

 new Galago of the Otolemur group was also secured at this place, and its screams 

 could be heard almost every night from the crowns of the trees. Still more noisy 

 and very numerous are the Tree Hyraxes {Procaria crawshayi). Of small rodents 

 Lophuromus aquilus, Arvicanihis pumilio diminutus and Dendromys insignis were 

 trapped in bush, and the Scrub Squirrel {Paraxerus jacksoni) was found to be common. 

 I did not see any larger Squirrel in this forest but Mr. Woosnam showed me once two 

 skins which were from the Escarpment and looked like melanistic specimens of Heliosci- 

 urus kenice without any white on the foreneck. A Cephalophus was seen a couple of 

 times in bush at the edge of the forest; but as I did not have any opportunity of 

 shooting it, I could not ascertain to which species it belonged. Bushbucks were 

 common, and a Kikuyu told me that they used to feed on some plants of the family
