bill).—ScuaTer, Catal. 1862, 359, No. 276%. ; 
Hab. Costa Rica. 
(No. 34,669, 2.) Upper part and sides of head, with the nape and the 
chin, ash color; the vertex soiled with rufous olive. A broad rufous band 
from each nostril over and behind the eye (the two confluent anteriorly), 
which is anterior to its middle point. Rest of upper parts olive green. Whole 
throat and breast greenish-yellow, the flanks and inner lining of wings purer 
yellow, as also to some extent a tinge on the crissum. Middle of belly white. 
Bill pale above; lower jaw dark plumbeous, with whitish tip. Legs flesh 
color. “Iris yellowish’’ (Carmiol). 
Second quill shorter than 10th; 3d about equal to Sth. 
(No. 34,669, 9.) Total length, 6.00; wing, 2.95; tail, 2.50; exposed por- 
tion of 1st primary, 1.15, of 2d, 1.85, of longest (5th) (measured from exposed 
base of 1st primary), 2.30; length of bill from nostril, .42, along gape, .80, 
depth, .33; tarsus, .86; middle toe and claw, .66, claw alone, .27; hind toe 
and claw, .64, claw alone, .30. 
Specimens differ in the amount of yellow on the under parts, 
which are sometimes entirely yellow (though paler behind), with 
the middle of belly only white; in other instances the middle of 
breast, belly, and the crissum are white. The flanks, however, are 
always yellow. Autumnal specimens show a buffy tinge in the white. 
Of the six specimens examined, all have the plumbeous spot on the 
bill. 
This species is easily distinguished from flaviventris by its whitish 
belly. Itis most closely related to C. flavipectus in its flesh colored 
legs and yellow breast, and in fact it is somewhat of a question 
whether they are specifically distinct. The Costa Rica bird is 
rather larger, and less brilliantly colored; the ash of the head is 
darker; the yellow of breast more olivaceous, and perhaps extend- 
ing a little farther back. The ochraceous wash of the hood is more 
marked, although both species vary among themselves in this as well 
as the other points. Better skins than those before me may, how- 
ever, exhibit the differences more satisfactorily.
