(Mexico). 
Hab. Southern Mexico and Guatemala. 
(No. 37,498, 5.) Upper part and sides of head, with nape, ashy, with a 
broad stripe of rufous brown from each nostril (the two confluent anteriorly) 
over and beyond eye to nape (the eye considerably anterior to the middle of 
the stripe); rest of upper parts olive green. Chin very pale ashy; rest of 
inferior surface, with inside of wings, bright yellow. Upper mandible pale; 
lower, plumbeous black, the end whitish. Legs apparently flesh color. ‘Iris 
cherry red.’’ Second quill shorter than the 10th; 3d less than the 7th. 
(No. 37,498, 5.) Total length, 6.10; wing, 3.25; tail, 2.95; exposed por- 
tion of Ist primary, 1.25, of 2d, 2.00, of longest (5th) (measured from ex- 
posed base of 1st primary), 2.55; length of bill from forehead, .85, from 
nostril, .50, along gape, .85, depth, .37; tarsus, .92; middle toe and claw, .75, 
claw alone, .30; hind toe and claw, .68, claw alone, .34. 
In the specimen described, and in fact in all before me, there is a 
faint wash of ochraceous on the vertex, though in several, as No. | 
30,874, the color of the ash is nearly pure. In this same specimen 
the ochrey color of the forehead extends over the lores, and involves 
the lower eyelids to a greater degree than usual. The ash of the 
chin is much restricted—being limited to the space between the 
rami. 
There is not much variation in the extensive series before me. 
The yellow is sometimes deeper in spring specimens; in autumnal 
it is paler, with a slight buffy tint. It is somewhat remarkable, 
however, that of four Guatemalan skins in the collection, three 
should lack the black of the lower jaw. The fourth, from Coban, 
a locality nearest of all to Mexico and Yucatan, is as described 
above. I can detect no other difference. All other specimens have 
the dark spot in question. 
The uniform yellow of the under parts sufficiently distinguishes 
this species from all its allies.
