and expeditions were made in all directions. Below our camping- 

 place the acacia-plain spread itself, broken here and there by 

 the so-called orchard-plain, which in its turn was continued by 

 the grass-plain. 



In the acacia-country at the foot of Elgon there was a rich 

 bird-life. Neophron monachus was very common and at times 

 they congregated in small flocks around my tent, otherwise this 

 bird was seen, as a rule, in the company of Fseudogyps africanus 

 africanus a,ud CorvuUur albicoUis, both of which where found in fairly 

 large numbers almost everywhere. I found F. a. africanus breeding 

 commonly in the trees fringing the small rivers flowing through 

 the plains, but 1 also found its nest in the depths of the forests. 

 Two specimens of Gj/ps ruppelU erlangeri were shot, although 

 in these regions this bird was rarely found. Milvus migrans 

 aegyptius and Buteo augur also occurred here. 1 also saw Helo- 

 tarsus ecaudatus and Serpentarius serpentarius several times. 

 Though Lophoceros melanoleucos suahelicus was mostly met with 

 in the interior of the forests, it was nevertheless not an un- 

 common sight to see a little family of 3 or 4 hopping about on 

 the branches of the acacias. 



Among the Weaver Birds occurring in this area, Euplectes 

 capensis xanthomelas, Fenthetria laticauda suahelica and Drepano- 

 plectes jacksoni were those most frequently seen. Neither were 

 Fhormopletces insignis insignis and Othyphantes reichenowi nigro- 

 temporalis, described anew by me from Elgon, rare. Only once 

 did I see Nigrita emiliae schistacea, and rather sparingly too did 

 Quelea sanguinirostris aethiopica occur. 



Those found most commonly, however, were Macronyx cro- 

 ceus, Dioptrornis fisheri, Frinia mistacea immutabilis, Bradornis 

 paUidus murinus and Saxicola torquata salax, the last-named 

 mostly frequenting the small acacias. On the dry branches of 

 old trees Buphagus erythrorhynchus could be seen now and then, 

 and Eurystomus afer rufobuccalis, either singly in or small flocks, 

 kept company with Crateropus melanops sharpei. Rather common 

 too were Corvinella corvina offinis, Lamprocolius chalybaeus 

 chahjbaeus and L. purpureus amethystinus. In places where the 

 trees grew thickly and brushwood occurred Dryoscopus gambensis 

 nyansae, Fiscus collaris Jiumeralis^ Melittophagus lafresnayi oreo- 

 bates^ Colius striatus ugandensis and many others were found. 



The Grrass-plain. 



Below the acacia-plain, orchard-plains and all other trans- 

 itional forms between these floral areas of the eastern slopes 

 the great, wide-spread savanna begins. In the transition from 

 the plain to the typical savanna a few solitary trees of different 

 kinds may be seen here and there. The climatic conditions of 

 the various regions vary very much at different places, but accor-
