almost unique; it was obtained many years since in 
Ireland, and is figured in Meyer’s British Birds. 
As space will not allow us to refer more particularly 
to the remaining species of Halaétus, we now pass 
on to the succeeding genus, Pandion, the Osprey. 
Ospreys are found frequenting situations similar to 
those inhabited by the Sea-Eagles, in most countries 
of the globe, and feed exclusively on fish, for the 
capture of which, their powerful talons and roughened 
soles are admirably adapted. The Osprey frequently 
pounces on fish with so great an impetus as to plunge 
completely below the surface of the water, from which 
it again rapidly emerges with the scaly prey grasped 
in its talons, which it then bears away to some con- 
venient perch, and forthwith devours. 
There is a slight variation in the size of the Ospreys 
found in different parts of the globe, on account of 
which some Naturalists have divided the genus Pan- 
dion into four species, but these seem rather to be 
mere local varieties of one widely spread and almost 
cosmopolitan race. 
We now come to the group of Kites comprising the 
following genera— Halastur, Milvus, Gypoictinia, 
Rosthramus, Nauclerus, Gampsonyx, FElanus, and 
Letina. 
The genus Halastur consists of four species, which 
are found in South Eastern Asia, the Islands of the 
Indian Ocean, and Australia, and which, like the Sea- 
Eagles, feed in great measure upon fish. The Indian
