BANGS CHIRIQUI BIRDS 59 



Vireo flavifrons Vieill. 

 One female, Boquete, 4000 feet, Jan. 22. 



Vireo carmioli Baird. 



One adult male, Boquete, 4500 feet, March 17. 



Hylophilus decurtatus (Bp.). 



Three adults, both sexes, Boquete, 4000 and 5000 feet, January 

 and April. 



Hylophilus ochraceiceps Scl. 



One male, Caribbean slope of Volean de Chiriqui, 4000 feet, 

 June 11. This specimen has a very large bill, much larger than 

 in examples of true H. ochraceiceps of Mexico ; and should others 

 prove the same, the southern form must be named. 



Cyclorhis flavipectus subflavescens Cab. 



Seven specimens, both sexes, Boquete, 4000 to 4800 feet, 

 January, March and April. 



Progne chalybea (Gmel.). 



Four adults, both sexes, Boquete, 4500 to 4800 feet, and Bogaba, 

 March, April and July. 



This northern form of P. chalybea, which Prof. Baird named 

 Progne teucogaster, is probably worth recognizing by name. I have, 

 however, seen no specimens from Guiann, and judge only by early 

 descriptions and figures.
