LOBIOPHASIS 
WHITE-TAILED WATTLED PHEASANT 
Family PHASIANIDAE 
Subfamily PHASIANINAE 
Genus LOBJOPHASTS 
Tue remarkably specialized Bornean pheasant which alone forms this genus 
finds a quite natural position at the extremity of specialized radiation of the Gexnaeus- 
Lophura group. As the maximum of plumage development has found vent in the 
secondary wing-feathers of the argus and the tail-coverts of the peacock, so in the 
Bornean Wattled Pheasant it is the tail itself which, in number of feathers, has 
exceeded all bounds for the family, and in the male consists of more than thirty 
feathers. 
No crest is present, but much of the head is bare of feathers, with the addition, 
in the male, of three pairs of highly developed wattles, a small pair on the lores on 
each side of the base of the culmen, a much larger pair on each side of the occiput, 
and an extremely long, more or less pendant, pair on each side of the throat. All 
three pairs of wattles are visible in the female in a rudimentary condition. 
The 1st primary is very much shorter than the 2nd, which is equal in length to 
the roth. The 5th is the longest in this series. 
The tail in the fully adult male is composed of thirty to thirty-two white feathers, 
the variation in number having nothing to do with age, but being a wholly individual 
character. The central pairs are extremely curved, and more than twice the length of 
the outer pairs. On many of the latter the web is defective or absent from much 
of the terminal portion of the shaft, which is thickened and spine-like. In the tail 
of the female there seems to be always twenty-six feathers, of more equal length 
than in the male. 
The spur is short and stout in the male, rudimentary in the female; the tarsus 
is considerably longer than the middle toe and claw.

The genus consists of but a single species, the White-tailed Wattled Pheasant, 
Lobiophasis bulwert Sharpe, and there is little chance that a second exists. As far 
as we know, it is confined to the central parts of Borneo.
