Description. — Above, including wings and tail externally, dull 

 green (between olive green and warbler green) ; center of the crown 

 chestnut, with lateral marginal stripes of black, meeting each other 

 on the forehead; broad superciliary stripe lemon chrome; sides of 

 the head below the superciliaries chestnut, sometimes inclining to 

 blackish on the lores; malar region and under parts lemon yellow, 

 with more or less shading of pyrite yellow on the sides and flanks, 

 the chin whitish; under wing-coverts dull yellowish white; bill 

 brownish black; feet pale (in skin). 



The sexes are alike. The black stripes on the pileum are irregular 

 in outline, and are not well marked in some specimens. 



Juvenal plumage : " above, including pileum, superciliary region, 

 and lores, plain sepia or bister brown; the remiges and rectrices 

 olive-green, as in adults; middle and greater wing-coverts tipped 

 with light fulvous or cinnamon-buff, producing two rather distinct 

 bands across wing; sides of head (except lores) plain olive, gradu- 

 ally fading into paler olive on throat and chest, this passing into 

 tawny olive or raw umber on sides and flanks ; abdomen, anal region, 

 and under tail-coverts pale yellow (straw yellow)" (Ridgway). 



Measurements. — Male: Wing, 56-64 (average, 60) ; tail, 52-59 (56) ; 

 bill, 9.5-10.5 (10); tarsus, 20-22 (21). Female (six specimens): 

 Wing, 57-62 (58.5) ; tail, 53-61 (58) ; bill, 10-11 (10.5) ; tarsus, 20.5- 

 23.5 (21). 



Range. — Highlands of southern Mexico, from Jalisco and Tamau- 

 lipas south to Orxaca. 



Remarks. — " This species, again, was described in 1840 [1841] by 

 Giraud as from Texas, but has not since been found nearly so far 

 north; so that this locality requires further confirmation. The first
