264 REMARKS ON SOME SPECIES OF THE 



The whole lower parts, but especially the breast, abdomen, 

 and lower tail-coverts (except of course the black tips), are 

 much more rufescent than in nipalensis, and may be called a 

 pale salmon buff — the wing-lining and axillaries being dull 

 salmon. The striae are much as in some nipalensis, but average 

 rather stronger. 



The second primary is 03 shorter than the first — a structural 

 peculiarity by which, if constant, this species may be at once 

 distinguished from nipalensis. 



The visible black portions of the upper tail-coverts are about 

 0*5, of the lower 0'65 to 0*7. 



The ear-coverts are brownish buff striated with dusky. 

 There is no trace of any white spot on the inner webs of the 

 outer (or any other) tail feathers in any of my four specimens. 



This species approaches closely to the true alpestris of Pallas 

 as described by him, but differs in not having the ears ashy, 

 in not having the rump almost to the middle of the back, pale 

 ferruginous, but having less than one-third of the back, bright 

 bay, in having only the tips of the upper tail-coverts black, in 

 having the wings below dull salmon colour not yellowish white, 

 in having the entire lower surface not lutescent or sordid white 

 but distinctly rufescent, in having the tail brown and not shin- 

 ing black, and in having no white spot on the tail. 



I have no doubt that, when a series of specimens are com- 

 pared, many other differences will be apparent. 



Lastly, we have a species very distinct from all our other 

 Indian ones, which I have as yet only received from Cachar 

 where it is a cold weather visitant, but which doubtless will 

 be found equally at that season in the valley of Assam, 

 Sylhet, &c. 



The nearest ally is striolata of Temminck, from which it 

 differs in its smaller size proportionally more forked tail, less 

 massive bill and much richer colored under parts. I pro- 

 pose for it the name of 



L. substriolata, N. S. 



Length, 775; wing, 5-0; tail, 4-0 ; fork, 2-25. 



A mere trace of a rufous collar. 



Rump and all but the longest upper tail-coverts, uniform 

 bright rusty rufous, or bay, each feather with a blackish shaft, 

 and in the case of those nearest the black ones, with distinct 

 though narrow shaft stripes. 



Rufous rump band TO to 1*1 in width. 



Longest black upper tail-coverts project 0*4 only beyond 

 bay ones.
