growth of the forest. At the time that it was shot it was 

 holding a piece of bark-fibre in its bill, probably for nesting- 

 purposes, as, on dissection, the testes were found to be large. 

 Locality. Londiani Forest, in British East Africa. 



Chloropeta massaica. 



S. 17.i. 14. 



A single example of the Yellow Flycatcher was shot on 

 tlie outskirts of the forest. It has quite a melodious 

 warble. 



Locality. Mabira Forest, in Uganda. 



Chloropeta natalensis. 



(J , and nestlings. 10. vi. 14. 



A pair nested close to my house in Nairobi, and a large 

 series of photographs was obtained. The nest was built 

 between the prongs of an upiight stem of a wild heliotrope. 

 The position was quite exposed. The nest was an untidy 

 structure, composed of coarse grass-blades externally, finer 

 ones inside, and grass-fibres as a lining. It was so deep 

 that when the bird was sitting the tip of the bill and tail 

 were the only parts of her visible. 



The clutch consisted of four eggs, almost spherical in 

 shape, of a pink colour with a few scattered liver-coloured 

 spots and streaks over a matt surface. Young birds are 

 very like C. icterina in colour, but browner above and paler 

 below. 



Locality. Nairobi, in British East Africa. 



Stizorhina vulpina. 



(5" 15 ; ? 7. Collected in every month in the year. 



This large series shows no variation in plumage. These 

 birds are common in the forests, where they keep to the 

 tree-tops. 



Localities. Mabira, Mubango, Kasala, and Dwimi Forests, 

 in Uganda. 



Megahias atrialatus.
