advances in agi; and the quill feathers of the wings and tail, together with 
the larger coverts of the former, are glossy black. 
The young bird of the first year, according to M. D’Azara, is entirely of a 
deep bluish tint, excepting the abdomen and lateral tail coverts, which are 
white. In the second year it assumes a dusky hue, marked by long white 
spots. Up to this pericd, the greater part of the head and neck is blackish 
violet. In the third year it assumes its adult coloring, with the exceptios 
ef a few black feathers among the upper wing coverts. 
The sange of this fine species of vulture is rather extensive. M. Bona 
parte enumerates it among the birds of the United States, and we’believe it 
is occasionally met with in Florida, which is probably its northern limit. 
Towards the south, M. D’Azara describes it as common in Paraguay, but 
says that it does not pass the thirty-second degree of latitude. In the inter- 
mediate countries it'would seem to be extremely abundant. Many travel- 
lers mention it as congregating in large flocks in various parts of Mexico, 
where it appears to have been first noticed by Navarrete, and was .von after 
described by Hernandez under the native name of cozcaquaubtli.  1ts more 
usual name, however, in that country, seems to be tzopiletl, literally king 
of the vultures. In Guiana it b&ars, according to Sonnini, a titie exactly 
synonymous ; and in Paraguay, according to D’Azara, that of iriburubicha, 
signifying the same thing. This uniformity of appellation is evidently 
derived from the universality of the belief, that the other vulwres pay a 
particular respect to this species, abandoning their prey to it, wnenever it 
makes its appearance among them, But such a concession, as D’Azara:
