BUTEO LAGOPUS (J. F. Gmelin*). 

 THE ROUGH-LEGGED BUZZARD. 



Buteo lay opus. 



THE ROUGH-LEGGED BUZZARD is at once distinguished 

 from the Common Buzzard last described, by having the 

 tarsi covered, in front and on the sides, with feathers as low 

 down as the origin of the toes, from which fact it has, with 

 some other species possessing the same peculiarity, been re- 

 moved from the genus Buteo, and made the type of a genus 

 Archibuteo, a course which has met with the approval of many 

 authorities. In its habits and powers, however, it resembles
