 Chiriqui.

 417 (San Miguel; Saboga; Pacheca). 



The Yellow-bellied Camptostoma was not collected by 

 Dr. BovALLius. 



Thayer and Bangs state, that the bird of the Pearl Is- 

 lands does not differ from that of Panama. Ridgway found 

 the islands specimens averaging lager and paler yellow below, 

 than those from the mainland, but remarks, that the difference 

 is by no means constant, some of them being quite as brightly 

 colored as those from the mainland. 



Thayer and Bangs record the finding on March 18th 

 of young in nestling plumage.
