1905.] BIRDS FROM TIBET. 55 



tail-coveros and lower flanks chestnut-red. Bill and legs dark 

 plumbeous, iris dull ciimson. Total length about lO'oO inches, 

 culmen 0*90, wing 4-50, tail 6-40, tarsus 1-50. 



From its nearest ally Garrtdax sannio, this species differs in 

 having the upper parts much darker and moi-e uniform in colour, 

 the crown not chestnut -bi'own, the under parts darker, without 

 any white or ochraceous on the belly, and in the tail having a broad 

 white terminal band. Ool. Waddell informs me that " it is called 

 by the Tibetans ' Jomo^ or the Lady ; it is found in the same 

 poplar and alder thickets as the Babax, but also comes up quite 

 close to the villages. It has the characteristic habits of a Babbler 

 in a marked degree, roves about in parties of eight or more 

 individuals, chatters more noisily, uttering its fluty call of 

 Whoh-hee, ]V}ioh-hee, is always on the move scampering along the 

 branches, is very secretive, seldom showing itself, and flying veiy 

 low across a clearance to the next cover." 



Lanius lama, sp. n. (Plate V. fig. 1.) 



Adult male (Tsangpo Yalley, Tibet, Sept. 1904). —Head, nape, 

 and upper parts generally dark plumbeous, much as in Lanius 

 algeriensis ; a narrow line across the forehead, the lores, and a 

 broad band through and behind the eye deep black ; lower rump 

 and upper tail-coverts rufous ; wings black, the inner secondaries 

 and larger wing-coverts narrowly margined with dull white ; tail 

 uniform blackish brown, rather pale at the extreme tip ; under 

 parts white, the breast, flanks, and under tail-coverts washed with 

 rufous fawn. Total length about 10' 10 inches, culmen 0'83, 

 wing 4-20, tail 5-0, tarsus 1-12. 



Lanius schach appears to be the nearest ally to the present 

 species, but the latter has only a narrow black line across the 

 forehead, the upper parts are much darker, it has no rufous on the 

 back or scapulars, but only on the lower rump and upper tail- 

 coverts, and has no trace of a white alar speculum. 



The other birds sent are Pica hottanensis, Turtur orientalis, 

 Otocorys elwesi, a young Lark which I cannot separate from 

 Alaiida arvensis, and Parus cmere?is, which, however, has a slightly 

 larger bill and longer wing than typical examples, but without a 

 series it is impossible to say if it can be regai'ded even as a 

 subspecies. 



All the above-mentioned birds were obtained in the Tsangpo 

 Valley, near the Chuksam Ferry, at an elevation of 12,100 feet 

 above the sea-level.
