36 ART. 13. E. LÖNNBEEG : 



NiKOLSKi found this bird but once in the western part of 

 the island, but a couple of specimens were collected by Poljakow 

 at Siska. It must certainly be a breeder in Saghalin as Professor 

 Ijima's expedition has found it during the whole summer. A 

 number of the species were observed on migration, together with 

 Poliomyias inugimahi and Xanthojnjgia narcissma narcissina, all 

 which had arrived at the shores near Korsakoff on May 30th.

 head brownish black with pale buffisli shaft-streaks. The long 

 feathers of the upper back have a broad bar or spot of a butHsh, 

 sometimes pale rufous, colour and are then again more or less 

 broadly edged with black. I3y this arrangement of the colours
