Above olive-green, head cinereous; well-marked superciliaries 

 white ; wings blackish ; wing-coverts broadly tipped with yellowish 

 white, which forms two cross-bands ; outer margins of secondaries 

 pale chestnut, forming a broad patch when the wing is closed ; 

 middle tail-feathers dark cinereous, three outer pairs nearly wholly 

 white : beneath white, belly, flanks, and under wing-eoverts tinged 

 with sulphur-yellow ; bill blackish, feet dark cinereous : whole 

 length 4 inches, wing 2, tail 1"8. Female similar. 



Hah. Ecuador and Peru. 



The pale chestnut patch on the secondaries renders this species 

 easily recognizable. Its correct position is still, to my mind, a little 

 uncertain : it is perhaps better placed here than in any other 

 recognized genus, but the wings and tail are much shorter than in 

 true Mecocerculus.
