14 FALCONID.E. 



afford the means of deciding between our two British Eagles 

 at any age ; and tlie three anterior toes of both species are 

 therefore figured as a vignette to the second British Eagle, 

 to show the distinction. The foot on the left hand is that 

 of the Golden Eagle, in which each toe is covered with 

 small reticulations as far as the last phalanx, then with the 

 three broad scales already referred to. In the foot of the 

 White-tailed Eagle, represented by the figure on the right 

 hand, the reticulations are confined to the tarsus, the whole 

 length of each toe being covered with broad scales. 



The figure of the Golden Eagle at the head of this article 

 was taken from a fine specimen at the Garden of the Zoolo- 

 gical Society, where it has lived for eight years. 



The figures below represent the crystalline lens and the 

 bony ring of the eye of the Golden Eagle, referred to at 

 page 11.
