and buffy orange. In the following spring the grey fea- 

 thers of the head still exhibit a slight mixture of olive- 

 green, and the chin is yellow, which in the more adult 

 male is white. 



The young female in spring has the head and ear- 

 coverts greyish brown ; the chin and throat buffy white ; 

 the upper part of the breast mottled with brown ; the 

 lower part of the breast, and the other under parts, prim- 

 rose yellow, enriched with a mixture of king's yellow. 



This bird may be distinguished from our common sum- 

 mer Yellow Wagtail, M. Rayi, next to be described, by 

 the white elongated line over the eyes and ear-coverts, 

 which appear to be permanent at all seasons, and by the 

 grey head, which is more or less conspicuous, also, at all 

 seasons, but particularly in summer. In Ray's Wagtail, 

 the line over the eye and the ear-coverts is yellow ; and 

 the head, I believe invariably, of the same colour as the 

 back of the bird. The females of the two species most 

 resemble each other.
