 out any red on the crown or dusky on the chin, and with portions oi the 

 plumage tinged with sulphur yellow. 



Adult female {male unhimvn). — Above olive-brownish, streaked with 

 dusky, the rump tinged with pale sulphur yellow; beneath whitish, 

 faintly tinged with dull buffy or pale fulvous on chest, the sides and 

 lower tail-coverts streaked with dusk}'; wings with two pale fulvous 

 bands across tips of middle and greater coverts; primaries and rec- 

 trices narrowly edged with pale sulphur yellow; wing, 76.20; tail,
