Desc7'^iption. — Pileum wnth two broad lateral stripes of black, 

 coalescing on the forehead, and inclosing a large coronal spot of 

 lemon chrome; lores blackish; supraloral spot and chin spot white; 

 sides of head (including superciliaries) and neck, and entire upper 

 parts, including the wings and tail externally, slate color to ^late 

 gray, the black more or less washed with olive green; under parts 

 lemon chrome, paler, even whitish, on the crissum and tibiae, the 

 sides washed with warbler green; under wing-coverts white; bill 

 black; feet pale (in skin). 



If the sexing is correct the female is like the male. A certain 

 proportion of the specimens examined, however, differ in having the 

 lateral crown-stripes restricted posteriorly, not extending over the 

 nape; the vertical spot, too, is duller and smaller, and the greater 

 wing-coverts show slight whitish tipping. These arc probably im- 

 mature. In Juvenal dress (illustrated by No. 172,243, Collection 

 American Museum of Natural Histor}', Portovelo, Ecuador, August 

 1) the general coloration is much duller, the yellow crown-spot alone 

 is indicated of the head markings, and the yellow beloAv has traces 

 of darker spotting.
