Hab. New Guinea. 



Chrysorrhos would perhaps be the better name for this species, 

 because all I have seen have the rump and base of the tail yellow,

 sent as C. chrysorrhos. L'niform ashy-grey ; face, throat, chest, and

 shoulders paler ; rump and base of the tail reddish-yellow ; cheeks, 

 throat and beneath white ; feet bright red. 



The two sides of this specimen are not coloured alike. The fore- 

 head of the skull is very convex.
