Chin and throat white with narrow brown tips. Under-parts dark brown faintly 

 banded with pale olive buff. Under tail-coverts with a conspicuous sub-terminal 

 band of white.

First Year Male Plumage.— Birds of this age have the head and facial border 

 with brown, not with pure black and white markings. The general plumage above is 

 more olive than in the adult, while the lack of the grey and white border robs the ocelli 

 of their firmness. These consist of considerable green iridescence in a large borderless 

 area of black. Terminally there is a broken incised band of pale buff, and just basal to 

 the ocellus is a more or less interrupted, but wide and conspicuous transverse band of 

 white, above which is another of black. The rest of the feather is black, vermiculatcd 

 and irregularly barred with grey and buff. The transition on the secondaries is on one 

 feather, the 8th, which has a symmetrical but very faint ocellus. 



The back and rump show traces of the distal black and white bands so distinct 

 above the ocelli, but they vary considerably, and are broken into large irregular spots. 

 The rest of the feather is mottled and vermiculatcd with buff. 



The rectrice ocelli, while all present, are very poorly defined, as they lack the framing 

 ring of grey. 



The chin and throat are white, but the under-parts less distinctly marked than in 

 the adults. 



Bill from nostril, 10 mm. ; wing, 183; tail, 233 ; tarsus, 6s ; middle toe and claw, 

 48 mm.
