Adult male: — Head, nape, mantle, inner and lesser wing 

 coverts shining black; ear coverts, sides of the face and throat 

 dark grey. Primaries and secondaries the bases of all the tail 

 feathers and the greater part of the two median pairs, black; 

 greater inner wing coverts with their terminal portions scarlet; 

 Primaries and secondaries from the fifth primary inwards with 

 their outer webs edged with scarlet, increasing progressively 

 inwards, the basal half of both webs scarlet orange. Rump 

 and upper tail coverts scarlet, under surface except the throat 

 and portion of the tail that is not black, scarlet orange, thighs 

 mingled black and orange buff or apricot; wing lining edge 

 of the wing and axillaries orange. Bill and feet black, iris dark 

 hazel. 



Adult female: — Distribution of colour similar to that of the 

 male, the red throughout being replaced by yellow intermediate 

 between "Cadmium Yellow" and "Light Cadmium" of 

 Ridgeway. The black of the upper surface more greyish blue 

 and less shining than that of the male and the ear coverts of a 

 paler grey. Chin and upper throat greyish white. Thighs 

 mingled white and brownish black. This is the stage described 

 as P. croceus by Ogilvie Grant {Fascic. Malay, loc. cit. p. 91.) 



Immature. — The immature of both sexes are similar to the 

 adult female, except that the head and mantle are of a paler 

 grey, with much less gloss and the yellow of the rump and 

 upper tail coverts has a strong cast of olive, while the bases of 

 the feathers are broadly grey, giving an impression of ill-defined 

 cross barring. This is the stage figured by Sharpe {loc. cit.) as 

 the adult female of P. wrayi. The adult male plumage appears 

 to be attained from this stage in part by a moult of the yellow 

 feathers and in part at least by a direct colour change, though 

 by the majority of authorities on moulting this is roundly 

 asserted to be impossible. • 



Juvenile. — Younger birds still resemble the immature 

 female but have a greenish tinge over the grey of the upper 

 parts, the ear coverts even paler grey and the feathers of the 

 head and mantle narrowly edged with dirty white.
