Tanagmdjs.] osteology avium. [Tanagrm. 



Calliste, Boie. 



Tricolor, Gm. 



Besides the above, I possess two other species of this genus,- — namely, Festiva, Sh., 

 and Thoracica, Temm., none of which differ in any respect that I can discover from 

 Nemosia. 



Euphonia, Desm. 



Pectoralis, Lath. 



I have also a specimen of Aureata. Vieill ; neither of them differ from Calliste, except 

 in not having the spine on the hinder portion of the palatine bones so much 

 elongated. 



Saltator, Vieill. 



Magnus, Gm. 



The Saltatorin<z do not appear to differ from the Tanagrince in the form of the skele- 

 ton, but may be distinguished by their large and robust bills. I have the following 

 species besides that named above : — Cyanopterus, Vieill; Cc&rulescens, Vieill; Pytylus 

 Gnaiho ; Pytylus torridus ; Pytylus, from Honduras; Arremon semitorquatus ; and 

 Diucopis capistratus, Bp.
