Adult male. Similar to that of 0. griseicauda, from which it differs 

 in being larger, in having more brilliant colours both on the upper 

 and under surfaces, the orange-brown spot on the sides of the neck 

 above the shoulder broader and more distinct, and the band across 

 the lateral tail-feathers blacker and better defined : " bill pale yellow- 

 green, the base dark olive-green ; iris red ; orbits bare green ; feet 

 red" (Wallace). Total length about 10-5 inches, wing 6, tail o -s , 

 bill 7, tarsus 0-9. 



Female. Differs from the male as does that of 0. griseicauda : and 

 besides it has the edges of the median and greater wing-coverts and 

 secondaries white, with a slight green tinge along the very edges, at 

 least in the Celebes birds, while in those from Sula Islands these 

 edges are yellowish white ; the white under tail-coverts are more or 

 less tinged with buff and mingled or irregularly banded with olive.
