ABOUT all we can certify to, so far, is that there are two varieties of the 

 Hermit Thrush which may be seen on Puget Sound during the migrations : a 

 lighter and grayer form, presumably from northwestern Alaska ; and a darker, 

 more warmly-tinted bird, H. g. nana, which may or may not summer to some 

 extent in western Washington. Specimens so far encountered in eastern 

 Washington are probably H. g. scqnoiensis. en route to or from their breeding 

 haunts in the high Cascades ; wdiile if any are ever captured in the mountains 

 of Stevens County, they will probably prove to be of the H. g. audiiboni type, 

 which prevails in the eastern portion of British Cohnnbia.
