48 BIRDS AND MAMMALS OF EAST SIBERIA [^' v'o^.V 



Nucifraga caryocatactes macrorhynchos Brehm. 



One adult male was taken at Shornoy Myss, March 3, 1912. 

 This bird was caught in an ermine trap baited with a piece of 

 fish. No others were seen, and the natives to whom Mr. Koran 

 showed the skin all said they had never seen one before. 



Perisoreus infaustus sibericus (Bodd.). 



Nine specimens, of both sexes, obtained at Nijni Kolymsk, 

 October and November, 1912. Apart from these nine birds, all 

 shot near his winter camp, Mr. Koren saw nothing of the species, 

 and he believes that it only straggles to the Kolyma region in 

 winter, its real home being in the hilly, forested country farther 

 south.
