Soon after the young have flown they congregate in families 

 and commence to moult, when they throw off their nest- 

 plumage and assume their first autumn^s garb, which greatly 

 difl'ers from that of the adults. In the plumage of the first 

 winter they are without any yellow colour. Soon after the 

 moult the families collect in flocks and migrate, the old birds 

 being still in their breeding-plumage, only a few having 

 assumed their winter dress. The majority of the young birds 

 migrate along with the old ones ; but some migrate separately 

 a little later. These are probably fledgelings of later broods, 

 and are seen throughout the whole Pamir, even at the end 

 of August, in parties of two to five, flying very slowly from 

 one swamp to another, gradually seeking their way. 



BUDYTES FLAVUS ? 



This bird was seen, during its migration, in the Pamir 

 Alichur early in the morning. I could not obtain a speci- 

 men. I noted that the birds had grey heads, green backs, 

 and yellow breasts ; but I cannot be certain whether they 

 were true B. flavus or B. cinereocapillus. 



MOTACILLA MELANOPE, Pall. 



The eastern form of the Grey Wagtail was found in the 

 Pamir Alichur at the end of August. It is a resident in 

 Turkestan generally, and ascends in summer high up into 

 the mountains, and winters down in the cultivated districts. 

 Probably it breeds in the Pamir, but not commonly. 



41. MOTACILLA PBRSONATA, Gould. 



Gould^s Grey-backed Wagtail was not observed at all, 

 either on the Alai or Pamir, until the end of August and first 

 days of September, when many specimens were obtained. It 

 flies in pairs. Some individuals winter in Ferghana. 



42. Accentor fulvescens, Sev. 



This Accentor breeds in the Alai mountains and in some 

 parts of the Pamir ; the young were found near Ran-kul at 

 12,000 feet in the middle of August ; and they were common 

 near the sources of the Kashgar Darya, between 11,000 and 

 13,000 feet, at the vend of July.
