Show 1905.] BIRDS FROM TIBET. 55 tail-coverts and lower flanks chestnut-rei. Bill and legs dark plumbeous, iris dull crimson. Total length about 10'50 inches, culmen 0‘90, wing 4‘50, tail 6'40, tarsus l -50. From its nearest ally Gctrrulax sannio, this species differs in having the upper parts much darker and more uniform in colour, the crown not chestnut-brown, the under parts darker, without any white or ochraceous on the belly, and in the tail having a broad white terminal band. Col. Waddell informs me that " it is called by the Tibetans Tomo,' 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, TF7loh-hee, is always on the move scampering along the branches, is very secretive, seldom showing itself, and flying very low across a clearance to the next cover." L astius l a m a , sp. n. (Plate V. fig. 1.) Adult male (Tsangpo Valley, Tibet, Sept. 1904).-Head, nape, and upper parts generally dark plumbeous, much as in Lanins 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 bottanensis, Turtur orientalis, Otocorys elwesi, a young Lark which I cannot separate from A lauda arvensis, and Parus cinereus, 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 regarded 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. E X P L AN A T IO N OF TH E PLATES. P l a t e IV .
