PALLAS’S SEA EAGLE. 17 
birds are in England, and will no doubt clear up the 
question as to whether it is a distinct species or not.” 
Mr. Gurney writes, “I think there is not the slightest 
doubt as to H. leucoryphus bemg as good a European 
species as any on the list. I had much conversation 
with Lieutenant Irby, who is an excellent observer. 
he = * It is, I understand, admitted to be 
European beyond any doubt, by the St. Petersburg 
naturalists of the present day, the only question being 
whether they are right or not in considering it identical 
with H. mace of India.” 
F. leucoryphus or macet, for we shall in this notice

by that excellent naturalist Pallas, and was recorded by 
him in his “Zoography of Asiatic Russia,” vol. 1., p. 352. 
He remarks that it was observed rarely in the vicinity of 
the Caspian, and that it nested in the woods surrounding 
that sea. He describes the bird minutely as being 
rather larger than the Spotted Eagle, and in habit 
between the Osprey and White-tailed Eagle. 
M. Eversmann again reports the occurrence of the 
same bird, as observed by him in his voyage to Bokhara. 
Schlegel gives not only Eversmann’s description but his 
own from the same specimen, in which he describes 
the bird as having the “figure, beak, feet, and organi- 
zation of H. macet.” 
F. leucoryphus belongs to the section of Sea Eagles 
forming the sub-genus Haliaetus of authors. Its home 
is the Indian continent, where it is common. Mr. Mc. 
Clelland, in writing in the “‘Proceedings of the Zoological 
Society,” in 1839, remarks of H. macei, “This Eagle 
preys on fish, and is particularly active during a storm, 
when it is found soaring over the lee shore, descending 
on such fishes as are driven into shallow water. During
