cester); Panay (Steere) ; Tawi Tawi (Bourns & Worcester). Celebes, Banggai 
and Saleyer Islands. 
Adult (sexes similar).—Above greenish yellow; feathers of crown with 
dusky centers; lores and sides of head lighter; a circle of feathers around 
eye bright yellow; under parts uniform bright yellow; wings and tail 
brown, the edges of the feathers greenish yellow, those of secondaries 
more yellowish. Upper mandible black; lower mandible pale yellowish, 
dusky along the edge; legs and nails dark brown. Length, 115. A 
male from Palawan: Wing, 59; tail, 48; culmen from base, 12; bill 
from nostril, 7; tarsus, 13. Female, wing, 55; tail, 48; culmen from 
base, 12; bill from nostril, 6; tarsus, 13. 
Young.—Three nestlings collected in Benguet Province, Luzon, on 
June 1, 1903, resemble the adults, but the upper parts are darker and 
more greenish; rump and edges of secondaries and coverts pale yellow 
and entire lower parts pale yellow, brightest on the abdomen. 
“The nine specimens collected by us in Tawi Tawi have the back 
slightly greener and show rather less yellow on the rump than do 
typical birds from the central Philippines. .A deep woods bird with 
rather a pleasant song. Quite easy to obtain when once seen, as it is 
not at all shy. 
“Three males from Tawi Tawi average: Length, 118; wing, 59; tail, 
48; culmen, 14; tarsus, 13; middle toe with claw, 11. Seven females, 
length, 113; wing, 54; tail, 44; culmen, 14; tarsus, 12; middle toe with 
claw, 11. Iris nearly black; legs and feet dirty yellowish brown; upper 
mandible black, lower yellow.” (Bourns and Worcester MS.) 
Genus CRYPTOLOPHA Swainson, 1837. 
Bill slender, depth and breadth equal at nostril; nasal and rictal 
bristles few and weak; wing longer than tail by less than length of 
tarsus; first primary more than one-half of second and less than one- 
half of third; fourth and fifth nearly equal and longest; tarsus slender 
and more than twice the bill from nostril. Small, inconspicuous birds 
with olive and yellowish green plumage; sexes similar. Some of the 
species resemble the members of the genus Acanthopneuste, but the very 
short first primary in the latter genus serves to distinguish it.
