plumage of N. luteifrons. In the British Museum there are 
two adults, one from the Camaroons ( Crossley), and an imma¬ 
ture bird from the Gaboon (Du Chaillu ), rightly determined as 
N. luteifrons. This immature bird has the plumage nearly 
uniform bluish grey, slightly darker above, and consequently 
differs from the type of N. lucieni and from a perfectly similar 
specimen from the Gaboon ( Walker ) in these two latter birds 
having the upper part of the head exactly similar to the adult 
of N. luteifrons , and on the sides of the head a broad black 
circle round the eye extending forward to the bill. Although 
I cannot prove that N. lucieni is not the adult female of N. 
luteifrons , I feel justified in keeping them separate. 
The third group consists of N. canicapilla , its northern 
representative, N. emilice , and the rufous-breasted N. bicolor. 
N. cinereocapilla 3 Sharpe, is only a printer's error for N. 
canicapilla. N. canicapilla , Hartl. (Orn. W.-Afr. p. 130), 
from Aguapim should, I have no doubt, be referred to N. 
emilice , which, from my own experience, is the common 
species near Abouri in those mountains. Although I have 
not seen a Senegambian specimen, I feel little doubt that the 
N. canicapilla , Rochebrune (Faun. Senegamb. p. 236), refers 
to N. emilice . The locality “ Gaboon ” for N. emilice , in 
Sharpe's Cat. Afr. B. p. 61, is, I think, undoubtedly incorrect, 
having been copied from a dealer's label.
