Myiozetetes similis superciliosus (Bp.). 

 Twelve specimens, both sexes ; Ceiba and Yaruca. 



Pitangus derbianus (Kaup.). 



Twenty-eight specimens, both sexes ; Ceiba and Yaruca. This series repre- 

 sents a form slightly dififerent from Mexican specimens upon which P. derbianus 

 was founded . The Honduras birds average a little smaller, and brighter yellow 

 below and darker, less rusty above. The differences, however, are slight, and 

 only show when large series are compared. I suppose it is the Sauraphayus 

 guatimalensis Lafr., a hardly well enough defined form to recognize by name. 



Megarhynchus pitangus mexicanus (Lafr.). 

 Four specimens, both sexes ; Ceiba and Yaruca. 



Myiobius sulphureipygius (Sol.). 

 One (J ; Yaruca. 



Empidonax traillii traillii (Aud). 

 Two specimens, (^ and 9 ; Ceiba. 



Empidonax flaviventris (Haiko). 

 Two males; Yaruca. 



Myiarchus crinitus (Linn). 

 Two males; Ceiba. 



Myiarchus mexicanus mexicanus (Kaup). 

 One adult ^■, Ceiba. 



Myiarchus la^wrencii lawrencii (Giraud). 

 Twenty-five specimens, both sexes ; Ceiba and Yaruca. 



Tyrannus melancholicus satrapa (Light.). 

 Seven specimens ; Ceiba. Some of these approach T. m. cuuchi.
