GENUS IV. CHOUGH.—PYRRHOCORAX, Cuvier. 
GENERIC CHARACTERS. 
Bill of mean length, slender, and arched, slightly com- 
pressed, with the end rather subulated, and drawn to a fine 
pomt. Nostrils open, basal, lateral and egg-shaped, hidden 
by the reflected bristles at the base of the bill. Feet strong. 
The tarsus longer than the middle toe. ‘Toes four, three be- 
fore and one behind, entirely divided. The fourth and fifth 
feathers the longest in the wing. 
For the separation of the Chough from the genus Crow 
(Corvus), I plead the authority of the most eminent natu- 
ralists of the present day. Nearly as it approaches to some 
of them in habits, yet it differs essentially from all the true 
Crows in the form of its bill. The genus at present contains 
four species, two of which are natives of Europe. The Cor- 
nish Chough is the only one found in Great Britain.
