DESCRIPTIONS OF THREE NEW SPECIES OF BIRDS OBTAINED 



DURING THE RECENT EXPEDITION TO LHASSA BY 



HENRY E. DRESSER, M.B.O.U., F.Z.S. 



[Received January 17, 1905.] 

 * (Plates IV and V.) 



Col. Waddell, C.B., who has recently returned from India, having been one 

 of the officers on the Tibet Expedition, when there made a collection of birds,, 

 most of which, he tells me, he Was able to identify by my '• Manual of Palasarctic 

 Birds". Some, however, he failed to recognize, and these he kept by him, and 

 has sent them on to me for identification, requesting me to describe any that 

 are new. The rest, however, were with his baggage, and were unfortunately 

 lost on the return march from Lhassa. 



Amongst the birds which were fortunately saved I find the following to be 

 undescribed, viz. : — 



Babax waddelli. sp. n. (Plate IV.) 



Adult male. (Tsangpo Valley, Tibet, 25th September 1904). — Upper parts 

 dull ashy grey, each feather with a broad central blackish stripe, the rump 

 slightly less striped than the rest of the upper parts ; wing blackish brown. 

 most of the feathers externally margined with ashy grey ; tail blackish brown, 

 much graduated ; under parts similar to the upper parts, but somewhat paler 

 and more narrowly striped ; bill and legs plumbeous, iris dull orange. Total 

 length about 12-60 inches, culmen 1*40, wing 5"10, tail G-50, tarsus 1*70. 



The nearest ally to this species appears to be Babax lanceolatus, from which,, 

 however, it differs considerably, being larger (wing 5'10 against 3'75, tail 6'50 

 against 5 - 0), and, as will be seen by the above description, it differs considerably 

 both in colour and markings. It is, Col. Waddell says, " called by the Tibetans 

 ' Teh-Teh* in imitation of its call. It frequents poplar and older thickets 

 remote from villages. It was gregarious, going about in parties of 8 to 10 indi- 

 viduals, but was not so active and secretive in its movements as the Garrulax, 

 alongside of which it was met with." 



Garrulax tibetanus, sp. n. (Plate V, Fig. 2.) 



Adult male. (Tsangpo Valley, Tibet, 25th September 1904). — Upper parts 

 dark brown with a tinge of olivaceous, the crown slightly darker ; lores and a 

 patch through the eye with the ear-coverts blackish chocolate ; quills 

 blackish, externally margined with slate or dark lavender-grey ; wing-coverts 

 like the back ; tail graduated, blackish brown broadly tipped with white ;
