in the interior districts of both sides of the Rocky 

 Mountains, but it is rare on the Atlantic coasts, 

 or near Hudson's Bay. 



The NUTCRACKER, the last British bird entering 

 among the Corvince, was separated generically 

 iron! the true Crows by Brisson, under the title 

 of Nucifraga. For a long period only one species, 

 that of Europe, was known. Lately Mr Gould 

 figured another very closely allied from the 

 Himalaya range, and the Prince of Musignano 

 and Mr Audubon have now ranked the Corvus 

 Columbianus of Wilson along with them. The 

 form is a very remarkable one, uniting the struc- 

 ture of the Crows with some of the habits of a 

 Scansorial bird.
