collected in Uganda and British East Africa. 381 



When comparing tliis series with birds from West Africa, 

 I could see no difference in the males, but the females of the 

 western birds were certainly more reddish on the back than 

 any of my skins. These birds were met with in the forest 

 and acacia country. They were nesting in April and June. 



Localities. Mabira, Kyetema, Katendi^ and Jinja, in 

 Uganda. 



Bias musicus.

These curious birds are not common. They were found 

 nesting in March and in September. The nest is a shallow 

 structure composed of fibres and rootlets, bound together 

 with cobwebs. Two eggs are laid, of a dirty greyish- white 

 ground-colour, speckled all over, but mostly at the larger 

 end, with grey-brown and brown spots and blotches. 



Localities. Mpamujugu, Mabira, Sezibwa, Katende, and 

 Kyetema, in Uganda. 



Hyliota flavigastra.

Not very common. They are usually seen in the forests. 

 The bird collected in November is an immature one, and has 

 the feathers of the mantle edged with ochraceous. 



Localities. Kaina, Mabira, Hoima, and Jinja, in Uganda.

These birds were nesting in June and November. They 

 build a small open nest of grass-fibres decorated with lichen. 

 The eggs, two in number, are very small and of a creamy 

 ground with brown spots, more abundant round the larger 

 diameter. Sometimes the spotting is equally distributed 

 over the surface. A young bird moulting from first to 

 intermediate plumage was shot in November. 



Localities. Chambura Kiver, Toro, Kyetema, in Uganda.
