(1893). 
(Plate XX VUT.) 
Adult Male—Crown and elongate crest dark green, shot with 
purplish-blue ; back of the neck, mantle, and -wings, black, 
broadly barred with greenish-blue, changing to dark blue and 
deep violet and fringed with golden-green ;. lower back and 
tail black, thickly spotted with rufous-buff, the longer upper 
tail-coverts, and tail-feathers with a pair of bluish-green ocelli 
changing to deep violet, each framed in a black and grey ring ; 
the latter absent on the inner webs of the outer pairs of tail- 
feathers ; the broad superciliary stripes* confluent on the nape, 
and a f¢riangular patch on each side of the head, pure white ; 
throat and under-parts d/ack ; naked skin round eye crimson. 
Total length, 19 inches ; wing, 7°3 ; tail, 8:7; tarsus, 2°5. 
Adult Female-—A we/l-developed crest brownish-black ; upper- 
parts pale rufous-brown, finely mottled with black ; feathers of 
the mantle and wing-coverts with an ill-defined band of rufous- 
buff near the extremity; longer tail-coverts zfhout ocelli ; 
ocelli on the tail-feathers as in the male, but much smaller and 
more widely edged with black only ; feathers on sides of face 
* Two species have generally been recognised, distinguished by the 
presence or absence of a white eyebrow. On this subject Messrs. Bourns 
and Worcester observe :—‘‘* While in Palawan we were so fortunate as to 
secure a series of eleven fully adult males of the Polyglectron inhabiting 
thatisland, Of these, ¢wo have not the slightest trace of superciliary stripes, 
while a third has only four small white feathers on one side. In each of 
the above there are a few white feathers on the nape, Three of our speci- 
mens perfectly agree with the description of typical P. xehrkorne. Three 
specimens have éyoad superciliary stripes, almost confluent on the nape, 
and in one bird the superciliary stripes which beg'n between the eye and 
the nostril are very broad, widening steadily towards the nape, where they 
are fully confluent, An examination of young birds, of which we have a 
good series, shows that the width and extent of the superciliary lines is 
independent of age. We therefore feel perfectly satisfied that P. zapoleonds 
and P. xehrkorne are identical, since the width of the white superciliary 
stripes is an uncertain quantity, subject to wide individual variation, and 
it may even be absent.”
