Adult male. Fore part of the head black, shading into dull crimson 

 on the occiput *, and bounded by a bright pink nuchal collar ; ear- 

 coverts, chin, and chest deep black; back rusty brown, shading into 

 rust on the rump and upper tail-coverts ; breast and rest of under- 

 parts scarlet-lake ; wings black ; quills with white bases, prima- 

 ries margined on the outer web with white ; outer webs of the 

 secondaries and whole of wing-coverts except the greater primary- 

 coverts with narrow distinct undulating white bars ; centre pair of 

 tail-feathers bright rusty brown, with a terminal black band ; second 

 and third pairs black, three outer pairs with the basal part black 

 and the terminal white closely vermiculated with black : bill pale

 the cheeks and round the eye violet ; iris red-brown ; feet dull 

 violet-blue. Total length 12 inches, wing 5-7, tail 6-6, tarsus 0-55. 



Immature, males have the black of the basal part of the chest 

 mixed with brown, the secondaries and wing-coverts like those of 

 the adult female, and the tail-feathers pointed, the centre pair being 

 devoid of a terminal black bar, and the outer pairs having the white 

 terminal part much more sparsely vermiculated with black : other- 

 wise the plumage resembles that of the adult. 



Still younger specimens have the breast entirely brown, and the 

 outer secondaries rusty buff irregularly barred with black.

 rust on the rump : chest reddish brown, shading into rusty on the lower 

 parts and sides of the chest ; breast and belly scarlet-pink ; under tail- 

 coverts rusty pink ; wings as in the male, but the secondaries and wing- 

 coverts are vermiculated and irregularly barred with rust-brown and 

 black ; tail as in the male, but the white terminal part of the three 

 outer pairs of feathers is less thickly vermiculated with black : naked 

 skin round eye and gape pale violet ; base of mandible cobalt-blue ; 



* In some Borneau specimens the dull crimson of the occiput extends to the
