wing, from tlie carpal joint to the end of the longest pri- 

 mary, five inches and a half : the first feather of the wing 

 very short ; the second equal in length to the fifth ; the 

 third and fourth feathers also equal, and the longest in the 

 wing. 



The female is rather lighter in colour than the adult male, 

 and the grey margins of the feathers are broader ; the band 

 across the chest is narrower ; the white colour is less pure, 

 and clouded with reddish brown and grey. 



Young males resemble the adult female ; but in young 

 females the pectoral gorget is scarcely perceptible. 



Specimens without the white crescent have been called 

 Rock-thrushes. White, and some otherwise marked vari- 

 eties, are said to have occurred. 



The vignette represents the form of the breast-bone of the 

 Blackbird, genus Tiirdus.
