milion, or red lead; hind toe standing inwards, and all of them 

 edged with a thick warty membrane. The male and female are 

 alike variable; and when in perfect plumage nearly resemble 

 each other. 



Bewick, in his History of British Birds, has figured and de- 

 scribed what he considers to be two species of Turn-stone; one 

 of which, he says, is chiefly confined to the southern, and the 

 other to the northern parts of Great Britain. The difference, 

 however, between these two appears to be no greater than com- 

 monly occurs among individuals of the same flock, and evident- 

 ly of the same species, in this country. As several years pro- 

 bably elapse before these birds arrive at their complete state of 

 plumage, many varieties must necessarily appear, according to 

 the different ages of the individuals.
