beneath ; the claw of the hind toe larger than that of the in- 

 ner, which again exceeds that of the middle and outer toes. 



This genus, of which our Sea-Eagle (Falco albicilla, Auct.) 

 supplies an example, differs from the Ospreys or true fishing 

 Eagles (genus Pandion, Savig.) in the form of the bill, and 

 in the claws being grooved, and not rounded beneath ; with 

 that upon the inner toe being much larger and stronger than 

 that of the outer, the contrary of which characterizes the ge- 

 nus Pandion. The plumage is also different in texture, be- 

 ing looser, and resembling that of the typical Eagles, and 

 the thighs, instead of a covering of short and thick set feathers, 

 are furnished with long plumes, a circumstance which indi- 

 cates a difference of economy. The habits of this genus are 

 less predatory, and their boldness is not so great as in the 

 members of the genus Aquila, added to which, their aspect 

 altogether approaches nearer to that of the Vultures.
