the thumb. Such, it is said, are its powers, that it has cleft a man’s 
skull with its bill; its ordinary food is the sloth, and it frequently 
carries off fawns. 
Morrunus, Cuv.* 
The Morphni, or Goshawk Eagles, like the preceding, have wings 
shorter than the tail; but their elevated and slender tarsi and weak toes 
compel us to separate them. 
Some of them have naked and scutellated tarsi.

It has a singular resemblance in colour and crest to the Great Fisher 
Eagle of the same country; but it is not so large, and its naked 
and scutellated tarsi sufficiently distinguish it; the mantle is black- 
ish, sometimes variegated with a deep grey; abdomen white, undu- 
lated more or less strongly with fawn colour; head and neck some- 
times grey, and sometimes white; the occipital tuft, long and 
blackish. 
F. urubitinga, L.; Spix, I. Black; no crest; rump and base of 
the tail, white. When young, brown above; fawn coloured, sprin- 
kled with brown beneath (Col. 55). This beautiful bird hunts on 
inundated grounds}. 
Others have elevated tarsi feathered throughout the whole of their length. 
F. occipitalis, Daud.; Huppart, Vaill. Afr. I. ii; Bruce, Abyss. 
pl. xxxii. As large as a crow; black; a long crest or tuft pendent 
from the occiput; the tarsi, borders of the wings, as well as of the 
bands under the tail, whitish. Throughout all Africa.

white; above white; flanks, thighs, and tarsi striped with black; 
tail, black, with four grey bands. A beautiful bird of South Ame- 
rica, varying from black and white to a deep brown §. 
Finally, America produces birds with bills similar to the preceding 
ones; very short reticulated tarsi half covered with feathers in front; 
wings shorter than the tail, and whose most distinguishing character con- 
sists in their almost closed nostrils, which resemble fissures. We may

Morphnus that Vieillot has made his Spizaetes.

{ This is certainly the Urutaurana of Margrave; but that author describes it as 
being of the size of an Eagle, which is at least one-third too large. The Harpyia 
braccata, Spix, III. is the young bird of the same species.
