Lake Crescent Trout 239 



The other cut-throat, popularly called "the 

 spotted trout " {Salmo clarkii jordana), is also 

 found in Lake Sutherland, and may be distin- 

 guished from its congener of the same waters, 

 the salmon-trout, by the orange or orange-red 

 color of its fins, by the red on the jaw, and " the 

 number and blackness of its spots and the darker 

 back." It is one of the most active of trouts, 

 and repeatedly and rapidly leaps after taking 

 the fly. 



The new species of salmon-trout found in 

 Lake Crescent, Washington {Salmo bathoecetor), 

 can be distinguished from others of its genus 

 of adjacent habitat, primarily by its long nose 

 and the absence of the red slash on the lower 

 jaw. It is also more slender, and the dentition 

 is much stronger than obtains in the other vari- 

 etal forms living in Lakes Sutherland and Cres- 

 cent. It lives in deep water, in some places over 

 seven hundred feet, and does not come to the 

 surface at any season of the year. The few 

 that have been caught were taken on set lines 

 within a foot of the bottom at a depth of about 

 two hundred feet. It is known locally as " the 

 long-headed trout."
