Colorado River Trout 



head, most numerous on the caudal and adipose fins; side with 

 pale blotches. Very much resembling the Colorado River trout 

 except that the scales are considerably larger and less crowded 

 anteriorly. 



Colorado River Trout 



Salmo pleuriticus (Cope) 



In all the headwaters of the Colorado is found another re- 

 presentative of the cut-throat trout series. It is abundant through- 

 out western Colorado and in all clear mountain streams in Arizona. 

 It is common in the Eagle and Gunnison where it reaches a 

 good size and is a game-fish of very high rank. 



Opercle short, 4| to 5 in head; scales small, 185 to 190 in 

 lateral line. Close to typical Salmo clarkii, but the black spots 

 gathered chiefly on posterior part of body, the head being nearly 

 immaculate. The colour is extremely variable, but the lower 

 fins are usually red, sometimes orange; usually a red lateral 

 band. A large, handsome and variable trout, sometimes profusely 

 speckled, sometimes with large spots, and occasionally with 

 strong golden shades.
