Pallas's Dipper is found throughout Eastern Siberia, whence it 

 ranges into Kamtschatka and the Aleutian Islands ; it also inhabits 

 Japan and the greater part of China, as Abbe David refers the 

 Dippers of Western China to this species and not to Q. asiaticus. 

 Mr. Hume has lately included the present bird in the list of Indian 

 birds ; but I have not found his authority for its occurrence, unless 

 it be that the Dipper from Ladak, identified by liim as C sordidas 

 (Lahore to Yark. p. 189), but supposed to be C. pallasi, really turns 

 out to be that species.

The Sombre Dipper inhabits the mountain-ranges in the extreme 

 northern portions of Cashmere and Ladak. It is also probably 

 found througliout the mountains of Thibet, as it has been discovered 

 by Prjevalski in Kansu and Northern Thibet.
