Col, Wadclell, C.B., who has recently returned from Indin, 

 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 Palaearctic 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 lest, however, were with his baggage, and 

 weie unfoi-tunately lost on the return march from Lhassa. 



Amongst the birds which were fortunately saved I find the 

 following to be unclescribed, viz. ; — 



Babax wadbelli, sp. n. (Plate IV.) 



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

 parts dull ashy grey, each feather with a broad central blackish 

 stripe, the rump slightly less striped than the lest 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 pai'ts, but somewhat paler and 

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

 Total length about i2"60 inches, culmen 1-40, wing 5'10, tail 6-50, 

 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 fi'equents poplar and alder 

 thickets remote from villages. It was gregarious, going about in 

 parties of 8 to 10 individuals, 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 Sept., 1904).— Upper 

 }iarts dark brown with a tinge of olivaceous, the ci'own slightly 

 dai'ker ; lores and a patch through the eye with the ear-covei-ts 

 blackish chocolate ; quills blackish, externally margined with slate 

 or dai-k lavender-grey ; wing-coverts like the back ; tail graduated, 

 blackish brown broadly tipped with white ; under parts rather 

 paler than the upper parts ; a broad white stripe below the eye, 

 and a few white featheis above the eye indicating a stripe ; under
