Stejneger, Further Notes on the Genus Acanthi's. [January 



process is finely illustrated by this series of Japanese birds. It 

 seems as if it is also connected with the change of the color of 

 the bill from yellow to black. As yet the phenomenon of the 

 renewal of the bill has received very little attention from ornithol- 

 ogists, notwithstanding its great importance. 



Not knowing of -any other species of Redpoll having been 

 assigned to Japan based on unquestionable identification I can at 

 present only regard A. holbtxllii as entitled to a place in its 

 fauna. It is reasonable, however, to expect that both A. linaria 

 and cxilipes in winter may visit the northern islands.
