Adult male. Head and neck blackish brown, the bases of the feathers white, the margins 
and snb-basal part of the feathers of the neck and sides of the head broadly washed 
with cinnamon, giving a streaked appearance to these parts; back and wings sepia 
glossed with purple, darkest on the mantle and shoulders; lower back paler; upper 
tail-coverts narrowly tipped with whitish; tail whitish brown, slightly mottled and 
washed with darker shades and crossed with four bands of blackish brown, a broad 
space (about 45 mm) separating the two endmost ones; throat white, with a black 
stripe down the middle 2) of it and at the sides (sub-malar stripe); breast and sides 
pale brownish rufous marked with broad drop-shaped spots of black and, towards 
the abdomen, irregularly with white ones; remaining under parts white, closely 
barred with brown, of a rufous tinge on the abdomen and blacker as well as more 
closely barred on the legs; under wing-coverts white, thickly spotted and barred 
with dark brown; quills below white varied with grey, brown towards the distal 
ends, and with more or less perfect remains of about five dark cross-bars, which are 
also perceptible on the upper side on the inner webs. “Iris gold-yellow; cere blue- 
grey; bill black; feet citron-yellow. Length 550 mm; expanse 1160.” ((5^, Tjamba, 
S. Celebes: Platen — Nr. 6670). 
Adult female measured by Dr. R. B. Sharpe has: wing 376; tail 274; tarsus 82.5 
(?92.5); culmen 42. 
A second specimen, from the neighbourhood of Manado (Nat. Coll.) is darker 
on the under surface than the above, especially on the abdomen. Head black; the 
black moustachial and throat stripes broad and well-developed (C 10846). 
Female. Much larger than the male. 
Young. Head and neck white, narrowly streaked on the crown and more broadly on the 
neck with dark brown; all other upper parts dark brown with a purplish gloss 
as in the adult, the unexposed inner webs of the secondaries white; upper tail- 
coverts tipped with white, the basal part of the feathers varied with white and 
barred with brown; tail much as in the adult, crossed with three broad bars; under 
smlace white, almost uniform on chin and throat, somewhat sparsely marked with 
drop — shaped spots of dark brown on the breast, a few broad but ill-defined marldngs 
of washy rufous on abdomen, indistinct bars of brownish rufous on the abdomen and 
under tail-coverts, and close bars of dark brown — narrower and less dark than in the 
adult — on the flanks and thighs; under wing- coverts white, spotted somewhat 
sparsely with dark brown; quills and tail below much as in the adult. (N. Celebes 
— Riedel in St. Petersburg Mus.) 
Another specimen, still younger, much resembles the above, but has still more 
white about it; sides of wing more mottled with wlfite; head and neck more 
narrowly streaked with brown; under surface white, marked with a few streaks of 
brown on the breast, thighs and flanks narrowly barred with rufous or brown, very 
indistinct on the inner side of the thighs; some brownish bars just discernible on 
t A name given for Spilornis rujipectus also. 
Prof. W. Blasius (6) has expressed the opinion that the black stripe down the middle of the throat 
mentioned by Bonaparte (2) does not really exist in this species. We find it to be always present in the 
adult and nearly adult, as shown by four before us, and Schlegel has described it in three in the 
Leyden Museum. It is, however, absent in the very differently plumaged young bird (see plate).
