on the ear-coverts, sides of occiput, nape, hind neck, throat and under- 
parts, darker and greyer on nape and hind neck, yellower on the abdomen, sides 
of jugulum and throat; chin whitish; back, scapulars and inner lesser wing- 
coverts mealy maroon-purple, becoming dark lead-grey on the carpal region; 
exposed ends and edges of middle wing-coverts citron-yellow, the concealed 
bases greenish slaty; greater coverts and secondaries black, edged with yellow, 
most broadly on the coverts, the innermost (;[uills olivaceous green on the oxiter web ; 
primaries slaty black, with a slight whitish external seam; rump, upper tail- 
covcrts and the two middle tail-feathers yellow-green (the tail-feathers having a 
black ground, therefore appearing darker); the other tail-feathers grey, with a 
blackish band about 3 cm from the tip; thighs yellow-green and white; under tail- 
coverts dull vinaceous rufous, the shorter ones broadly tipped with whitish; under 
wing-coverts and quills below slaty, blackish near the .shafts, the outermost two 
or three blackish externally ((J’, Kalibangkere, S. Celebes, 25. IH. 78: Platen — 
0 13234). 
Iris yellow; feet red; claws grey; bill greenish black (Meyer & 4); iris orange- 
red; feet light cherry-red; bill horn-yellow-grey (Platen b 6). 
Female. Differs from the male in having the back and inner wing-coverts yellow-green like 
the rump, not mealy maroon; the borders of the middle wing-coverts white, of the 
greater coverts pale yellowish; under tail-coverts wliite, irregularly barred vdth green 
and olive-greyish (Q, S. Celebes: C 13235). “Iris golden; feet red; bill yellow-green, 
darker at the base” (P.&F. Sarasin, $ Kema). 
The male in first plumage probably resembles the adult female. (See young male of 
0. sangirmsis.)
