ring is divided at the nape in one specimen only out of seven, in two others it is 
nearly divided, in the other four it is complete. An intermediate position seems most 
correct for them. 
The species. 
Figure and descriptions of the species in general: Meyer e V (skeleton); Walden cl, 
Brliggemann d 1, Sharpe e 1, W. Blasius c 8. 
Adult. Yellow, washed with ochraceous on the back and scapulars, inner quills greenish 
yellow externally, centre tail-feathers greenish yellow, pure yellow at the tip, preceded 
by a small subterminal patch of black, undersurface deep gamboge-yellow; a broad 
circlet of black passing from the lores through the eyes towards the nape 
^ (where it meets in this specimen); bastard-wing and quills black, the latter 
edged with whitish; lateral tail-feathers yellow, partly black on the basal third 
of the outermost, the black increasing in extent by gradations on the outer and the 
inner webs of the others till it occupies most of the fifth pair; under wing-coverts 
and edge of metacarpus yellow; quills below shining drab, whitish fawn where 
they rest upon the body (N. Celebes: Riedel — Yr. 5201). 
“Iris red; feet bluisli grey; claws black; bill rosy” (Meyer c 6). 
Sexual differences. Two females from S. Celebes examined by Prof. W. Blasius (k 2) differed 
by the lighter brownish colour of the quiUs, and the broad, paler yellow border of 
the secondaries, as of the primaries; while five males had the quills black, with 
narrow pale borders, and the inner secondaries with intense, sharply defined, yellow 
outer webs. Unlike Prof. W. Blasius, we suspect that the complete black coronal 
circlet in North Celebes is a sexual character. 
Young. Differs from the adult by wanting the black coronet; paler yellow below, breast 
greenish yellow -with blackish shaft-streaks; head and back greenish olive yellow; 
quiUs light broAvn with pale borders; centre tail-feathers olive [-yellow], (cf. Bias, h 2). 
Immature. We agree with Prof. W. Blasius that the absence of black near the tips of the 
two middle tail-feathers is a sign of immaturity.
