B. poliocephala is a very beautiful species, with the throat 

 white and rest of the underparts golden yellow. The head 

 is grey forming a distinct cap, and the rest of the upperside 

 olive-green. As is usual with this genus, the male is very 

 much larger than the female, and has a wing-measurement 

 of 107 mm. as against 91'5 in the female. The species is 

 apparently confined to Cameroon Mountain.

I have been unable to separate specimens of B. tephro- 

 Icema from Fernando Po from typical examples from the 

 Cameroon Mts. ; the latter are, however, on an average 

 slightly larger and possibly a little lighter on the underside. 

 The difference is so slight that the island form is best united 

 with that of the mainland.

This is the first occasion upon which B. poensis has been 

 obtained on the mainland. 



Considerable differences in size exist between the two 

 sexes, the males being larger in every way than tlie 

 females. Specimen (No. 1), although said by the collector 

 to be a female, is obviously a male bird, with the wing 

 measuring 87 mm. as against 73 and 79 in the hens.
