Adult male. General colour above yellowish olive-green ; head 

 jet-black, separated from the back by a coUar of rich yellow : lores, 

 feathers round the eye, and ear-coverts black ; chin black ; cheeks 

 and throat bright yellow ; rest of the under surface of the body bright 

 orange-yellow, with a very broad black gorget occupying the lower 

 throat and fore neck, and joined on each side to the black ear-coverts ; 

 wing-coverts and quills blackish or black ; the lesser and median 

 coverts and the secondary quills broadly, the primary and greater 

 coverts very narrowly margined with yellowish olive ; upper tail- 

 coverts and tail-feathers black, the latter with very narrow tips of 

 yellowish ; thighs and under tail-coverts bright yellow, the former 

 with black bases near the tibial joint ; flanks slightly washed with 

 green ; under wing-coverts bright yellow, the greater series white, 

 very faintly washed with yellow ; quills blackish below, edged with 

 white along the inner web. 



Young male. Similar to the adult, but duUer olive-green, the 

 head only rather darker than the back ; all the wing-coverts and 

 the outer webs of the secondary quills broadly margined with olive- 

 green, aud uniform with the back ; upper tail-coverts oiive-green, 

 slightly more yellow ; tail blackish, strongly washed with olive, 

 especially on the margins and at the tips ; the black spot on the chin 

 absent ; the black collar round the fore neck not so broad and not 

 so deep black as in the adult male. 



Young male (one of the types of P. cliristopliori of Tristram). 

 Like the young male described above, but yet having the ear- 

 coverts olive-brown, and with only a few faint traces of the black 

 coUar. 



Female. According to Tristram, like the male, but wants the 

 black collar. 



Ohs. The diagnosis given by Tristram for his P. christophon (S) 

 agrees with an immature male of P. astrolali, Bp.
