ring is divided at the uape in one specimen only out of seven, iu two others it is 

 nearly divided, in the other four it is complete. An intermediate position seems most 

 correct for tliem. 



The species. 



Figure and descriptions of the species in general: Meyer e V (skeleton); Walden c 1, 

 Briiggemann d 1, Sharpe e 1, W. Blasius c 8. 



Adult. Yellow, washed with ochraceous on the back and scapulars, inner (juills greenish 

 yellow externally, centre tail-feathers greenish yellow, pure yellow at the tip, preceded 

 by a small sub terminal patch of black, under surface 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 outei-most, the black increasing in extent by gradations on the outer and the 

 inner webs of the others till it occupies most of the fifth paii*; under wing-coverts 

 and edge of metacarpus yellow; quills below sliining drab, whitish fawn where 

 they rest upon the body (N. Celebes: Riedel — Nr. 5201). 



"Lis red; feet bluish grey; claws black; bill rosy" (Meyer c 6]. 



Sexual diflferences. Two females from S. Celebes examined by Prof. W. Blasius (k 2) differed 

 by the lighter brownish coloiu- of the quills, 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 oHve yellow; 

 quills Kght brown with pale borders; centre tail-feathers oHve [-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.
