Worcester) ; Palawan (Platen, Whitehead, Steere Exp., Everett, Bourns & Wor- 

 cester) ; Panay [Steere); Tawi Tawi (Bourns £ Worcester). Celebes, Banggai 

 and Saleyer Islands. 



Adult (sexes similar) .^Aho\e 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, 13; 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 Acanthopneu^te, but the very 

 short first primary in the latter genus serves to distinguish it.
