Fringillidae. 



Acanthis linaria linaria (Linn.). 



Only one specimen was taken, an adult female, at Nijni Kolymsk, 

 Oct. 18, 1911, and Mr. Keren's notes make no mention of the 

 species. 



Acanthis holboelli (Brehm.). 



Only one specimen was in the collection, a fine adult male from 

 Nijni Kolymsk, Oct. 2, 1911, and Mr. Koren had nothing to say 

 about the species. 



Hartert has suggested, in ' Die Vogel der palaarktischen Fauna,' 

 that Holboll's redpoll, on account of its distribution in the breed- 

 ing season, cannot well be regarded as a subspecies of linaria. 

 It breeds, he says, in little colonies scattered here and there 

 throughout the breeding range of true linaria. Such being the 

 case, of course the form must be accorded specific rank. 



Acanthis hornemannii exilipes (Coues). 



Six adults, of both sexes, were obtained at Nijni Kolymsk, 

 October 2-18, 1911. 



The hoary redpoll was very common in the Kolyma region, and 

 in fact all along the x\rctic coast of Siberia, in summer, and Mr. 

 Koren believes that some remain throughout the winter in the 

 wooded regions near Nijni Kolymsk. He saw numbers of the 

 species as late as November 7, 1911, and as early as March 11, 1912. 



[^Plectrophenax nivalis nivalis (Linn.). 



Five specimens, of both sexes, Nijni Kolymsk, October 4-25, 

 1911.
