wings, and tail, glossy blue-black; under parts cinereous; chin, a narrow 
line on middle of breast, center of abdomen, crissum, thighs, axillars,

Length, 90; wing, 53; tail, 25; culmen from base, 10; bill from nostril, 
6; greatest width of bill, 7; tarsus, 14. 
“Adult female-—Above brown, head faintly washed with olive; back, 
wing-coverts, and outer webs of secondaries heavily washed with olive- 
yellow, rump almost entirely of the latter color; entire under surface 
grayish white faintly tinged with olive-yellow, lighter along center of 
breast and abdomen; under wing-coverts, axillars, and inner webs of 
quills pure white.

secondaries, the wing and tail being black as in adult male.” (Bourns

“The locality Panaon, assigned to this species in the Catalogue of 
Birds, is a manifest error. The type specimen, an unsexed bird which 
was rightly supposed to be a male, was obtained in Cebu by Everett. No 
additional specimen seems to have been secured until 1892, when we again 
found it in Cebu. Ten males average as follows: Length, 90; wing, 52; 
tail, 26; culmen, 11.4; tarsus, 13.4; middle toe with claw, 13.7. Six 
females, length, 89; wing, 52; tail, 25; culmen, 11:6; tarsus, 13.4; 
middle toe with claw, 14. Iris chocolate-brown; bill, legs, feet, and 
nails black. Breeding in June. Food fruit.” (Bourns and Worcester 
MS.)
