 HANGS CHIRIQUI BIRDS _ Vol.111 



Mr. Brown did not get G. chiriquensis Salvin, and though con. 

 stantly on the lookout for it, never saw it. ' It must be a very local 

 species, perhaps found on a large savanna on the northern slope 

 of the volcano, that Mr. Brown did not visit. He heard that one 

 of Arce's men collected some birds on this savanna years ago. and 

 he meant to visit the place, but time did not permit. 



Oporornis formosa (YVils.) . 



Two males, Boquete and Volcan de Chiriqui, 7700 and 4500 

 feet, Feb. 22 and March 3. 



Seiurus noveboracensis (Gmel.). 

 One male, Boquete, 4000 feet, March 27. 



Seiurus aurocapillus (Linn.). 



Two specimens, male and female, Boquete and Volcan de Chiri- 

 qui, 4000 and 7700 feet, Feb. 20 and April 15. 



Dendroica aestiva (Gmel.). 



( )ne male, in the autumnal plumage of a young bird, Pedregal, 

 Aug. 21. This seems an early date for the summer yellow bird to 

 reach Panama, hut probably the autumnal migrants arrive in Cen- 

 tral and South America much earlier than we are accustomed to 

 think they do. 



Dendroica blackburnia? (Gmel.). 

 One adult male. Boquete. 4000 feet, March 27. 



Helminthophila peregrina (Wils.). 

 One adult male, Boquete. 4000 feet. Jan. 18.
