tipped with white, presenting the appearance of a very wide band between of brownish black with a violet tinge. Body above 
and below dark brown, in some specimens nearly black on the under parts.

entire under parts yellowish white, with large oblong and circular spots of brown; upper and under tail coverts white ; tail 
brown, with many bands of a deeper shade of the same color, and with the inner webs yellowish and reddish white ; base and 
tip of tail yellowish white. 
Total length, female, 22 to 24 inches; wing, 15 inches; tail, 10 inches. Male, total length, 20 inches; wing, 13 to 14 
inches ; tail, 9 to 94 inches. 
Hab.—Southern States, Mexico, South America. Spec. in Nat. Mus. Washington, and Mus. Acad. Philada. 
The observations of naturalists attached to the late expeditions demonstrate this bird to be of 
common occurrence in Texas, on the Rio Grande. It is a dull and heavy bird in its habits, 
and subsists for the greater part on dead animals. 
This bird appears to belong to the genus Crazirex, as given by Mr. Gould, if not identical 
with his species.
