84 ORNITHOLOGY. 



Hab. — South America. Specimen in Nat. Mus. Washington, and 

 Mus. Acad. Philadelphia. 



Obs. — All the specimens that we have seen of this vulture are from 

 "Western and Southern South America, and at present we are not in- 

 formed whether it inhabits the countries on the Atlantic or not. This 

 species is an exceedingly near relative of the common turkey buzzard 

 of North America, and is only to be distinguished on careful compari- 

 son. So far as can be judged from prepared skins, the present is a more 

 slender and rather smaller bird in all its measurements; with compara- 

 tively longer wings and shorter tail. Its general appearance and appa- 

 rently its habits also are very similar to the northern species. 



5. Cathartes bukroyianus, Cassin. — Burrough's Vulture. 



Cathartes lurroviaynis, Cassin, Proc. Acad. Philada. II, p. 212 (1845). 



Not figured. 



The smallest of all vultures. Resembling C. aura and C. jota, but 

 smaller, and without a ruff on the neck, as in those species. Plumage 

 on the neck ascending behind, as in G. atratus ; bill rather short; aper- 

 tures of nostrils large ; wings long ; tail rounded, rather long. 



Entire plumage deep uniform black ; more uniform than in either 

 C. aura or G. jota. Shafts of quills white. Head and neck red. 



Total length about twenty-two inches ; wing eighteen inches ; tail 

 eight and a half inches. 



Hab. — Mexico, Vera Cruz, Mazatlan, Lower California. Specimen 

 in Mus. Acad. Philadelphia. 



Obs. — Though European ornithologists have been rather disposed to 

 regard this species as identical with G. jota, it is really quite distinct 

 from both that and G. aura, more so, in fact, than they are distinct 

 from each other. The present bird may very readily be distinguished 

 by its small size and general resemblance to G. aura, but with the re- 

 markable character of the plumage ascending to a point on the back of 

 the neck, as in 0. atratus. All the specimens of this bird that we have
