Myiozetetes similis superciliosus (BP.). 
Twelve specimens, both sexes ; Ceiba and Yaruca. 
Pitangus derbianus (Kavp.). 
Twenty-eight specimens, both sexes ; Ceiba and Yaruca. This sefies repre- 
sents a form slightly different 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 Sduraphagus 
guatimalensis Lafr., a hardly well enough defined form to recognize by name.
