places there is no sub-vegetation, and these parts strongly recall 

 our palaearctic woods. Other parts again — and these comprise 

 the largest area of the forests ~ have an almost impenetrable 

 sub-vegetation of thicket and liana, through which it is almost 

 impossible to force one's way. Here and there small mountain 

 streams rush along, on the banks of which huge ferns and creepers 

 form dense groves. 



On the outskirts of the forests in the direction of the acacia- 

 country JBarus alhiventris, Serinus albifrons Icilimensis, Batis 

 moliior puella, Cinnyris reichenoivi, Anfhreptes coUaris ugandae, 

 Chalcomitra senegalensis aequatorialis, Cyanomitra verticalis vi- 

 ridisplendens and others were found abundantly. All these fre- 

 quented places where the trees stood solitary and separated by 

 smaller or larger bushes, i. e. in the sunlit and more open parts 

 of the forests. On the banks of the small streams, where they 

 plunged down the naked sides of the mountain, Motacilla longi- 

 cauda skipped about, and the bushes close to the water were 

 frequented by Ceryle maxima, while small flocks of Neisna quar- 

 tinia nyansae flew here and there. 



The low trees in the open patches of the forest-glades were 

 inhabited by Earisoma lugens jacJcsoni, Campophaga quiscalina 

 martini, Apalis pulchella, Barbafula simplex leucomystax, Barhar 

 tula bilineaia. The first nest I found of Turacus hartlaubi medius 

 was situated in a thick bush on the fringe of the forest. Re- 

 markably enough, I also found Chrysococcyx hlaasi here a few 

 times and it was in this locality that the extremely beautiful 

 ChloropJioneus dohertyi was shot. 



In the interior of the forests Turacus hartlaubi medius was 

 one of the commonest birds, but only a few times did I see Muso- 

 phaga violacea rossae. Another bird occurring quite as often was 

 Coracina caesia pura. The most frequently occurring pigeon was 

 Turturoena delagorguei sharpei, which was found almost every- 

 where. Next came Streptopelia lugens funebr a and Columba arqua- 

 trix. In the regions through which our expedition passed Vinago 

 calva salvadorii was less common. 



In the tops of the Bodocarpus trees swarms of Boeocephalus 

 gulielmi massaicus were seen, sharing the fruits of the trees with 

 great numbers of Amydrus wallery elgonensis, Bholia sharpei and 

 Cinnyricinclus leucogaster verreauxi. Up and down the rugged 

 trunks of the aged forest-giants climbed Gymnobucco bonapartei 

 cinereiceps and in like manner Campothera taeniolaema and Ben- 

 dropicos lafresnayi lepidus were often seen. From the dense 

 foliage the notes of Oriolus percivali were heard, which bird was 

 found in large numbers, and Apaloderma narina narina tried to 

 hide its bright colouring among the kingdoms of the flowers and 

 the leaves, where also Zosterops virens jacksoni in small flocks 

 scrambled with hissing cries on the outer tips of the branches. 

 In flocks of 4 — 6 in number (sometimes more) Irrisor bollei
