 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 breast, sides, and flanks, 

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