Specimens differ in the amount of yellow on the under parts, 

 which are sometimes entirely yellow (though paler behind), with 

 the auddle of belly only white ; in other instances the middle of 

 breast, belly, and the cr'ssura are white. The flanks, however, are 

 always yellow. Autumnal specimens show a buffy tinge in the white.

This species is easily distinguished from Jlaviventris by its whitish 

 belly. It is most closely related to C. Jlavipectus 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 ochraceoua 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.
