 edged with green on the outer webs ; the second, third, and fourth 

 primaries, the bastard- wing and primary-coverts with dark bluish- 

 green margins ; under wing-coverts green ; tail-feathers olive-

Hah, Ndoruma, Equatorial Africa. 



The only specimen known of this species is intermediate be- 

 tween P. fuscicajjillus and P. flavifrons ; it has the head and neck 

 brown like the first, and the rest of the body and also the size similar 

 to the second, which it resembles also in the green under wing- 

 coverts ; on the head there are two yellow feathers, which perhaps 

 show that, at a more advanced stage, all the head would have be- 

 come yellow. I suspect that the specimen examined is a young of 

 P. flavifrons.
