106 FALCONID. 
rufous axillaries, under wing-coverts, and thighs, is found only in Brazil ; H. bidentatus, 
which has white under wing-coverts and rufous flanks, inhabits Amazonia and Guiana 
to Colombia; while H. fasciatus, which differs from the last-named species only in its 
banded flanks, is found in Central America from Panama to Mexico. 
The genus is distinguished from the other American Kites by the double tooth 
in the upper mandible, in which respect it approaches the Falcons ; Harpagus has, 
however, the unmistakable soft plumage of the Kites, and is probably not far removed 
from Ictinia, though lacking the long wings of the latter.

H. fasciatus is nearly allied to the South-American HH. bidentatus, but differs in 
having a more banded under surface, and the greyish bars are broader and more 
distinct on the sides of the body. 
The species is nowhere common, though extending from Mexico to Panama. It 
was first described by Lawrence from Guatemala from a specimen acquired by 
Van Patten !, and we possess an example from the same country obtained by Skinner’, 
Another was also sent by Ascoli from Vera Paz in 1893, but we did not observe it 
there. A specimen in the British Museum, received from M. Bouvier, and said to
