This bird is a summer resident in Northern Japan, Kamt- 

 schatka, and the Aleutian Isles (Temminck), migrating for the 

 winter to the islands of the Indian Archipelago. In its migra- 

 tions it passes the coasts of China and Formosa in September 

 and April. I have procured specimens at these seasons at Amoy; 

 and in Formosa I obtained three adults in summer plumage, 

 and three immature birds at the end of August and beginning of 

 September. According to Cassin, it also occurs on the coasts of 

 Western America. The plumage of this species, in the imma- 

 ture winter and summer dresses, has been well described by 

 Schlegel in the * Fauna Japonica.' The young bird is mottled 

 on the dark parts of the breast and flanks, and freckled on the 

 scapulars and wing-coverts, with whitish. It is in this dress the 

 T. pulverulentus of Miiller. In the summer plumage it is spotted 

 on the throat, and barred irregularly on the breast and flanks 

 with blackish grey. In the winter, the breast is of a uniform 

 colour with the back. It is then the T. cinereus of Gray's 

 ' Genera.^
