Ichthyological Notes.- - In the Ihil/rlln oj ihr Bnmiu of Fisheries 

 (vol. 25, 1905), Dr. Hnrton \V. Ev(>nn:inn luis a hcaiitifiilly illustrated 

 memoir on the "Golden Trout of the Iliu'h Sierras." In small streams 

 tributary to Kern River, along the flanks of Mount W hitney are found 

 small trout, very gorgeously colored, with brilliant golden and orange 

 shades on the bodies and fins. These colors harmonize with the 

 orange colors of the underlying rocks. Recently Dr. P^vermanii, at 

 the request of President Roosevelt, conducted an investigation of 

 these trout. He finds them probably (Ic-xviidcd from the Kern River 

 Trout {Sahw gilberti Jordan), but nioditicd in >\y.r, in coloration, 

 and in the reduction of the scales. Troni die Kcni River Trout, the 

 Golden Trout are se{)arated by impassable \\aterfalls. Rut still more 

 remarkable is the fact tliat in each of the three different streams thus 

 isolated, there is a ditlVreiit type or sp(>eies of Golden Trout.
