the eyelids whitish. Under parts pale yellow, lightest (almost white) on 
throat, darker inside the wings and on crissum; flanks slightly olivaceous.

of other quills olive. Tail feathers decidedly olive, edged internally with 
yellowish. Bill above ‘horn color, flesh color below; legs plumbeous. 
(No. 38,926, 4.) Total length, 4.30; wing, 2.25; tail, 2.05; difference of 
10th and longest primary, .31; exposed portion of lst primary, .80, of 2d, 
1.45, of longest (4th) (measured from exposed base of Ist primary), 1.75; 
length of bill from forehead, .61, from nostril, .35, along gape, .66; tarsus, 
-62; middle toe and claw, .46, claw alone, .13; hind toe and claw, .46, claw

The specimen described agrees quite well with the type, but is 
larger and brighter in color. The shade of olive in the cap is 
darker and redder than that of the back. 
This species, of about the same size, closely resembles viridi- 
Jlavus in color, especially below. The latter is, however, of a 
richer, more ochrey yeliow below, lacks the colored front, and has 
the cap uniform with the back. The whole bill is reddish, and the 
feet are flesh color or red, not plumbeous.
