base of caudal. Pectoral four-sevenths of space to ventral. Ven- 

 tral inserted a little behind dorsal. Caudal slightly lunate. Dark 

 olive above. Sides with many red spots, usually smaller than 

 pupil. Back more or less barred or mottled with shade darker 

 than ground-color. Dorsal and caudal barred or mottled with

A beautiful fish, of clear cold streams and best suited to the 

 northern counties, and the chief object of pursuit to the true 

 angler. Its beauty and combined characters of excellence as 

 both a table-fish and game-fish have led to its introduction into 

 streams not originally stocked.
