32 BANGS CHIRIQUI BIRDS [ ^i.^li ' 



It has been doubted l if this is more than a color phase of 2 . 

 paella. In the present large series there is not a sign of any- 

 intermediate coloring, adult males, adult females, and young 

 males all being perfectly characteristic of one or the other species. 

 The two birds occur right together, although on the Volcan de 

 Chiriqui T. aurantiiventris is much the commoner. 



Mr. Brown had splendid opportunities of observing the birds in 

 life and is convinced that they are distinct species; he told me 

 that whenever he saw a pair together, always it was two red-bellied 

 or two yellow-bellied birds and never a red-bellied with a yellow- 

 bellied. 



The difference in color is just the same that distinguishes T. 

 chionura from T. bairdi, but these two have different geographic 

 ranges, while 2. puella and 2. aurantiiventris are found in the 

 same region. 



Galbula melanogenia Scl. 

 Three adult males, Bogaba, July. 



Capito salvini Scl. 



Twenty specimens, both sexes, Boquete, Volcan de Chiriqui 

 and Caribbean slope, 4000 to 5000 feet, January to June. 



Tetragonops frantzii Scl. 



Nine specimens, adults of both sexes and one young female, 

 Boquete and Caribbean slope of Volcan de Chiriqui, 4000 to 

 7000 feet, March, April and June. 



All females lack the black occipital crest. The one young 

 example is like the adults in color, but has a much weaker bill. 



Pteroglossus frantzii Cab. 

 One adult female, Boquete, 3000 feet, January.
