Ceryle americana septentrionalis Sharpe. 

 One adult J ; Yaruca. 



Glaucidium griseiceps Shakpe. 

 Two specimens, (J & 9 ; Yaruca. 



Nyctidromus albicollis (Gml.). 

 One (J ; Ceiba. 



Phaethornis longirostris longirostris (Less, and Delatt.). 



One adult ^ ; Ceiba. 



Amazilia tzacatl dubusi (Bourc. and Muls.). 

 Six specimens, both sexes ; Ceiba and Yaruca. 



Amazilia cyanocephala (Less.). 



One adult 9 ; Y'aruca. After studying all the material in Washington, — 

 collections U. S. National Museum and Division of Biological Survey, — I can- 

 not satisfactorily separate by external characters or geographic range the sub- 

 species A.guatemalensis Gould. The present example is true A. cyanocephala. 



Thalurania to-wnsendi Ridg. 



One adult ^ ; Yaruca. This very distinct species is still a rare bird in col- 

 lections, and so far as known has a very restricted range. 



Heliothrix barroti (Bodrc. and Mdls.). 

 Two males ; Ceiba and Yaruca. 



Trogon melanocephalus Gould. 



Seven specimens, both sexes ; Ceiba. 



Trogon caligatus caligatus Gould. 



Five specimens, both sexes ; Yaruca. On comparing these and Mexican 

 specimens with skins from Panama, I find that the latter represent a very well- 

 marked subspecies, differing from the more northern bird — true C. caligatus —
