species. The common name of the European bird, viz., 

 the Carrion Crow, points to a characteristic difference of 

 habit. The feathers of the breast and front of the neck 

 are stiff, sharp-pointed, and lustrous, in the European bird, 

 very much Uke those of the Raven ; while in the American 

 species they are soft, downy, and uniform. The bill of the 

 European species is also more hooked than that of the 

 American. 



The common Buzzard of Europe, Buteo vulgaris, has 

 been by some regarded as identical with the American 

 species ; but from a slight examination of the specimen 

 before the Society, Dr. Cabot was disposed to doubt the 

 correctness of this opinion. The American is a southern 

 species, the European a northern one. So far as careful 

 comparisons have been made, none of the species of birds 

 in the middle temperate regions are the same in both con- 

 tinents.

 tome, from Isle Royale, Lake Superior, the first of this
