] 34 Mr. A. G. More on the Distribution of Birds 



la the neighbourhood of Glasgow, Mr. R. Gray describes the 

 Hooded Crow as constantly pairing with the Carrion-Crow, and 

 says this is the rule I'ather than the exception ; and in Rennie's 

 ' Field Naturalist' (1833, p. 279) Mr. Blyth records that the 

 same observation has been made near Inverness. This circum- 

 stance is greatly in favour of the opinion that the two birds are 

 races of the same species. 



Blasius treats the Hooded Crow as variety /3 of C. corone.
