List of Birds, with Descriptions of JS T ew Species* 175 



Panama bird to hirundinacea I had no specimens of that spe- 

 cies with which to compare, but soon after receiving examples 

 of both sexes, found I had erred in doing so. On a new exa- 

 mination it agreed better with E. crassirostris, but as they dif- 

 fered in some important characters I concluded to let it remain 

 as it was for further "investigation. Ten specimens from Chi- 

 riqui and Panama, now before me, have invariably much 

 smaller bills than my examples of crassirostris from Bogota, 

 being nearer those of hirundinacea ; the coloring of the hind 

 neck and back in the males is steel blue with a slight violaceous 

 tinge, these parts in crassirostris are of a decided reddish violet , 

 quite as much so as in E. violacea. 



If these differences are not sufficient to admit of its specific 

 separation, they at least give it the position of a well character- 

 ized permanent variety. 



The female is of a bright olive green above, and below of a 

 rather bright olivaceous yellow, lighter in the middle of the 

 abdomen. 



12. Calliste Francesco} (Lafr.). 



13. Tojiagra diaconus, Less. 



11. Ramphocelus dimidiatus, Lafr. 



15. Ramphocelus passerinii, Bp. 



16. Pyranga wstiva (Gm.). 



17. Saltator striatijyecfais, Lafr. 



18. Saltator intermedins, Lawr. 



Apart from the black throat band being smaller, in this spe- 

 cies the under plumage has a decided wash of fulvous, whereas 

 in magnoides the breast is of a clear cinereous ; three specimens 

 in the collection agree with my types, and twelve specimens of 

 magnoides from Gautemala, differ from the others as above 

 pointed out ; all the specimens of intermedins seem smaller 

 than the allied species. I have seen no specimen from Gau- 

 temala answering to my description of the female, which much 

 resembles S. magnus. See Phil. Proc. 1861, p. 106.
