from 26° to 68° north, and is abundant along the northwest coast of America. It has recently- 

 been separated from its closely allied species the Golden-eye (F. glancion) of Europe. It is 

 not confined to the seacoast, but is common along the rivers of the interior, where its flesh 

 (probably from change of food) is considered to be unsavory. On the seacoast, its flesh is 

 much esteemed.
