tips — the tail being pale glossy black, white-tipped, and 
with a broad median white band. The whole under 
surface is rusty-red, the hinder breast being darker, 
shewing obscure cross bars remaining from the younger 
plumage in which the entire under parts are narrowly 
barred with brownish black. 
The primary quills of the wings in this species are 
much longer than the secondaries, more so in fa6t than 
by the length of the tarsus ; and the nostrils are round, and 
show a very conspicuous tubercle inside (marks of the 
genus). 
What has been said of the habits, occurrence and 
distribution of the two preceding species, applies equally 
well to this form, which, however, seems to be a much 
more a6live bird, with stronger and more rapid flight — 
and it is much more frequently seen sweeping along on 
the wing, especially over the wet savannahs and 
swampy places, than either of the others. 
The next species to be mentioned, the "black-hawk" 
or t€ black chicken hawk" (Urubitinga zonura), will 
readily be known by its size and colouring. It reaches 
a length of from 23-25 inches, according to the sex. 
The colouring is black, almost throughout, with the 
exception of the tail and its covering feathers. The 
base of the tail, and a narrow tip, are white, the remain- 
ing part being black, forming a very conspicuous band ; 
and the tail coverts are white, more or less marked with 
black, In the young stages, the general colour above is 
brown, more or less varied with a reddish tint, while the 
head, neck and under surface is of a reddish and whitish 
yellow, spotted and streaked with brown and brownish- 
black. The tail is pale brown, numerously banded with
