112 A MONOGRAPH OF THE PHEASANTS 
rump and the coverts. Tail pale buff, with the basal half black. On the outer feathers 
the buff is sometimes confined, even on old birds, to a small terminal patch on the 
outer web. 
The remaining under-parts slightly glossed with dark steel-blue, and all under tail- 
coverts plain steel-blue ; lower belly dull brown, with enlarged flattened shafts of most 
conspicuous shining white. The shape of the breast feathers is wholly unlike that in 
erythrophthalmus, being rounded in the latter, but pointed in Ayvonotus, with the shafts 
very unlike. In exythrophthalmus the rhachis is dark and normal in shape, tapering, 
and splitting up as usual into terminal barbs. In the Bornean bird the rhachis for 
the terminal third is expanded and flattened, and of a shining ivory white. In its 
enlarged condition it extends clear beyond the terminal barbs as a strong white spine. 
Bill yellow, black at base, scarlet facial skin covered with finger-like papillae and a 
sparse scattering of hair-like, degenerate, simple featherlets. 
The spurs are curved, and from 15 to 33 mm. in length. The measurements are: 
bill from nostril, 18; wing, 235; tail, 148; tarsus, 81; middle toe and claw, 51 mm. 
Immature males have the lower back much darker, the golden is more tarnished, 
mixed with reddish. 
ADULT FEMALE.—Crown dark brown. Chin, throat, ear-coverts and sides of neck 
paler, smoky brown. Nape, belly and flight-feathers dull brownish black. The 
remainder of the plumage black, glossed, especially strongly on the upper surface, with 
dark steel-blue. 
Upper mandible dark, lower yellowish. Bare facial area scarlet. Iris dark brown. 
Spurs straight, 15 mm. in length. Bill from nostril, 15; wing, 220; tail, 135; tarsus, 76 ; 
middle toe and claw, 48 mm. 
EARLY HISTORY 
Temminck was the first naturalist to give this bird a name, but as he never published 
it, it counted for naught. J. E. Grey, in his “Illustrations of Indian Zoology,” figured 
it, but gave it the same title as the Malayan bird, which by a printer's error reads 
erythrothalmus. In 1844, G. R. Gray called the species Ayvonotus, but gave no descrip- 
tion of it, so it remained for Dr. Sclater nine years later to finally correlate the bird with 
its scientific name and description. Elliot says that a male bird was living in the 
London Zoological Gardens in 1870, but I can find no other record of it.
