324 WAGTAIL. 



A. — This is similar to the other, but is seven inches and a half 

 long; the tail measuring at least four inches; the six middle feathers 

 are black, the outer one all white, the two next white on the inside, 

 and blackish on the out ; the rest of the plumage as in the last 

 described, from which it seems chiefly to differ in the extreme length 

 of the tail. 



This appears at Gibraltar at the same season, but in small num- 

 bers, compared with the others, has the same manners, and takes 

 its departure at the same time. Is common in all the deserts of 

 Tartary, and is seen to run like a mouse among the high grass.* 



Mr. White considers it as a distinct species. I observed a female 

 in some India drawings, at least seven inches long, above fine blue 

 grey ; sides of the head and beneath white ; breast and on the ears 

 bluish white, on the former a transverse blackish mark.
