338 NEW BIRDS FROM COSTA RICA CHERRIE. 



SO deep a black, while the rufous tips and edges are broader ; the wings 

 and tail are dusky, the latter edged with the color of the back and the 

 former with olive-3'ellow, brightest and lightest on the inner second- 

 aries ; lesser wing coverts like the back, middle coverts lighter like the 

 edging to the remiges, greater coverts with similar edges but having 

 an orange shade. Below, chin and throat grayish white; breast, sides, 

 and flanks greeuish-j^ellow; abdomen and under wing coverts yellow 

 (nearly the primrose of Ridgway's " Nomenclature".) Striations on the 

 under parts are obsolete. The size is considerably smaller ; wing, 1.70 ; 

 tail, 1.50, 



To this apparently new bird I have given the name Lophotriccus 

 zeledoni, taking pleasure in this opportunity to show some appreciation 

 to Sr. Don Jose C. Zeledon for many favors, personal and otherwise.

 stiffened stems of the rectrices beyond the webs of the feathers, but

 8ittasomu,s, slightly compressed for the terminal half and slightly
