 region, back to about 2.54 mm. behind the eye, gamboge yellow, soiled by indis- 

 tinct olive-greenish tips to the feathers; rest of upper parts uniform olive-green, the

 cut off from it by the interposition of a blackish line connecting the dusky of the 

 auriculars with the black of the lores. On each side the crown, a black line, com- 

 mencing over about the middle of the eye and extending backward for about 7.11

 decidedly paler and duller on the tail-coverts; sides of lireast, sides, and flanks, 

 strongly shaded with olive-green; under wing-coverts grayish white, tinged with yel-
