Mr. J. H. Gurney^s Notes on, 
andj as an instance of its doing so, I may mention tliat the 
Norwich Museum possesses the head and foot of an Eagle, 
apparently a young bird of this species, which was obtained 
in the island of Mauritius, as already recorded in ^ The Ibis ^ 
for 1869, p. 449. 
Judging from this foot, it would seem that the groove on 
the lower surface of each claw, and especially of the hinder 
claw, is decidedly wider in H. vociferoides than in H. vocifer, 
in which latter bird these grooves are narrower and more 
contracted than in any other species of Haliaetus, In the 
remarks on H. vociferoides in ^ The Ibis ^ for 1869, to which 
I have already referred, I alluded to that species as apparently 
occupying an intermediate position between H. vocifer and 
H. leucoryphus, to which latter species I will now pass on, and, 
with it, will conclude my observations on the genus Haliaetus. 
Mr. Sharpe gives the geographical habitat of H. leuco- 
ryplms as extending from Burmah as far westward as the 
Caspian; but there is, I think, no doubt that the Sea-Eagle 
observed and obtained in the Crimea by Col. Irby, and re¬ 
corded in the Zoologist,^ vol. xv. p. 5353, and in The Ibis*’ 
for 1861, p. 223, was of this species ; and a probable instance 
of its having nested still further westward, in the Pravidy 
valley, Bulgaria, is recorded by Mr. Earman in ^ The Ibis ■’ 
for 1869, p. 202. 
The northern range of this species is not referred to by 
Mr. Sharpe, but appears to extend to Mongolia and Eastern 
Siberia, and probably also to China; for further details on 
this subject 1 would refer to the article on this Eagle in 
DresseEs ^ Birds of Europe,'’ to the translation of Prjevalsky’s 
Mongolian notes in the ^ Ornithological Miscellany,’ vol. ii. 
p. 148, to Dr. Finsch’s observations recorded in The Ibis ^ 
for 1877, pp. 53, 54, and to David and OustalePs Oiseaux 
de la Chine,^ p. 14. 
Mr. Sharpe refers in a footnote to a specimen of this Eagle 
in the British Museum as marked by Mr. Gray as the true 
H. leucoryphus (Pall.), but without any register or trace of 
its origin.^’ I am happy to be able to clear up the obscurity 
attending this specimen, as I was informed by Mr. Gray,
