The study of the group of Blue Tits led the author to 

 the conclusion that Cyanistes jjleskei and C. flavipectus are 

 old forms, which are being bred-out by crossing with 

 C. cyanus and the intermediate forms ; and he goes on to 

 consider the question with relation to Corvus corone and 

 C. comix, Buteo vulgaris of Western and B. vulpinus of 

 Eastern Europe, Falco eleonora and F. arcadicus, the 

 members of the genus Cyanecula, the Nuthatches, and many 

 other birds belonging to the above and other families. The 

 three ways in which these crossings influence the colour of 

 the plumage is only briefly touched upon, and this subject 

 is reserved for future investigation.
