454 Mr. J. H. Gurney^s Notes on 



and^ as an instance of its doing so, I may mention that 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. vocifei'oides 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- 

 ryphus 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. Farman 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 I would refer to the article on this Eagle in 

 Dresser^s ' 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 Oustalet^s ' 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,
