214 Major H. J. Kelsall on 



Dendromus caroli. 



Only seen in heavy forest, and there not frequently. The 

 green colour about the head of this bird appears to be 

 acquired^ in part at any rate, from green lichen or fungus 

 on the trees with which it comes in contact when searching 

 for food. If rubbed with a damp cloth some of the stain 

 comes oflF. 



Dendromus maculosns. 



Dendromus nivosiis. 



Dendropicos lafresnayi. 



Dendropicos luguhris. 



These four species are found in fairly open bush country. 



Family Capitonid^. 



Lyl3ius bidentatus. 



Frequently found in open bush country. 



Irides dark brown, orbital patch pale greenish yellow; 

 bill pale yellowish white. The sharply cut-oif patch of 

 white on the flanks is very conspicuous in flight. 



LyMus rubescens. 



There appears to be a gradation in the tone of colouring 

 from L. vieilloti of Abyssinia and the White Nile region 

 through the Senegambiau form to that from Sierra Leone. 

 The amount of red on the breast gradually increases and 

 the whitish colour of the back decreases in passing from 

 east to west and south. In the West African form the 

 underparts are generally deeper yellow^ and the bill is of 

 a smaller average size. 



I once or twice heard this bird give a curious call like 

 " k'ak, k^ak, k'ak, hoo, hoo, hoo," the latter syllables having 

 the same ocarina-like tone that most of the Barbets have. 



Gymnobucco calvus. 



I found this bird in forest only. 



Barbatula erythronota. 



Barbatula chrysopyga. 



Both common. The call of both species is a clear " Tioo- 

 hoo, hoQ-hoo'' that of B. chryso'pyga being a little higher in 

 pitch.
