556 PIITLLOSCOPUS VIRIDANUS. 



Presuming, however, that the P. plumbeitarsus of Swinhoe is the same as P. viridanus (and Mr. Seebohm 

 informs me that he believes in the identity of the two species, the former being the summer plumage of the 

 latter), the range of this Warbler becomes enormously extended, and reaches " in the breeding-season 

 the subalpine districts of the North-eastern Palasarctic Region from the Ural to the Pacific. Prjevalsky found 

 it in the breeding-season in the pine-districts of Camsu.' It passes through China on migration, and probably 

 winters in Burma and the East-India islands" [Seebohm). The identity of this northern species with our 

 Indian P. viridanus might account for the fact of a skin of the latter having been identified by Messrs. Brooks 

 and Seebohm in a collection made in the month of August in the Ural. It has likewise been recently procured 

 in Heligoland by Herr Gatke. 



On the other hand, however, Mr. Brooks gives it as his opinion, in the last number of ' Stray Feathers ' 

 (vol. vii. pp. 508-10), that Swinhoe's species is distinct from the present. He points out, among other points, 

 that P. plumbeitarsus has a stronger, differently shaped and coloured bill, two wing-bars instead of one, which 

 arc yellowish instead of white, and also a darker upper plumage than P. viridanus. 



Mr. Brooks found its nest in Cashmere at an elevation of about 1000 feet ; it was a domed structure, 

 on the steep bank-side of a ravine full of small birch trees.
