[The Massai Yellow Flycatcher was observed near Entebbe, all around Euwenzori, 

 and in the Semliki Valley near Fort Beni. On Kuwenzori it was found up to an 

 elevation of 6000 feet, but not higher : at 7000 feet a very similar species, C. kenija, 

 takes its place and ranges up to 10,000 feet. Its favourite haunts are low-lying damp 

 places and valleys, where there are tall grasses or reeds and dense undergrowth. —

This apparently immature bird differs from all known species of Chloropeta in 

 having a longer and more slender bill and the feet and claws greatly developed. 

 The latter peculiarity is well shown in the accompanying text-figure 13, in which the

foot of C. gracilirostris is compared with that of C. kenya, a species of about the same 

 size as regards the wing-measurement. It is most nearly allied to G. kenya Sharpe, 

 from which it differs principally in its somewhat darker olive upperparts and in the 

 absence of a superciliary stripe. The type-specimen has the edges of the flight- and 

 tail-feathers as well as the upper tail-coverts dull reddish-brown, and the lower back, 

 sides, and flanks washed with the same colour. 



Iris dark reddish-brown ; bill brown ; feet black. 



Total length about 5"4 inches; culmen 0'G3, width at the base of the nostrils 0'2; 

 wing 2'5 ; tail 2'4 ; tarsus I'O. 



[A few of these Flycatchers were found inhabiting the dense papyrus-swamps and 

 reed-beds along the shores of Lake Albert. They were apparently rather uncommon, 

 but the difficulty of seeing birds which live in such situations may have misled us 

 in this respect. — H. B. W.']
