The Nutcracker, the last British bird entering 
among the Corvirue, was separated generically 
from 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.
