mandible, while in the harpy it is nearly median in 
position ; while in the feet, the bare tarsus is long and 
slender, and the toes and talons thin and weak, com- 
pared with the thick and massive corresponding parts 
in the harpy. The colouring of this species is very 
similar to that found in specimens of the harpy, 
the upper surface and the crest being more or less 
brownish-black, mottled or barred in the greater part 
with ashy — more especially in the long tail which is 
whitish at the tip and at the base, and is crossed with 
three distinct ashy-bars ; and the under surface brown- 
ish-grey or white, more or less barred with nairow 
reddish-brown bands, especially on the shortfeathered 
thighs. 
This species seems to have much about the same 
distribution in the colony as the harpy, being never 
met with actually in the coast districts — but little or 
nothing is known of its habits. 
Very different from either of the preceding are the 
two species of the so-called crowned eagles (Spisaetus) , 
which both have their legs feathered to their toes. 
This character alone will serve at once to separate them 
from all the other hawks. Neither of the species occurs 
on the coast, but they are at times met with in the forest 
districts of the interior along the great rivers, where 
they seem to prefer the more elevated tradls or the 
more secluded parts. With their raised crest, which 
attains a length of about 3-4 inches, these birds present 
a very fierce appearance, quite in keeping with their 
habits.
