REPORT OF STATE BOARD OF FISH COMMISSIONERS 109 



broad rich cadmium band on the belly are characteristic. The varia- 

 tion in the black spots is inconsiderable. In the 29 specimens which 

 I have examined critically 15 do not show any spots whatever anterior 

 to the adipose fin, and only 2 of the remaining 14 show any spots 

 anterior to the dorsal fin, and these are obscure and few in number. 

 In one large specimen there are bu1 12 to 14 spots on the caudal 

 peduncle; in another somewhal smaller example there are but 6 

 spots. The dorsal, anal, and ventral fins are invariably edged with 

 brighter color. The head in the males is longer and more pointed; 

 the maxillary is also longer than in the females. When well spread the 

 caudal fin is usually slightly lunate or slightly notched, but in some 

 examples it is almost truncate or square. In alcohol all of the bright 

 colors soon fade, the parr-marks, black spots, and pale edges to the 

 dorsal, anal, and ventral fins persisting. The general color of the 

 body then becomes a dirty yellowish while or in some specimens 

 brownish. In some cases the parr-marks almost wholly disappear. 



The type specimen of this species is No. 53064, X. S. Nat. Mus. 

 Cotypes are No. 53400, U. S. Nat. Mus.. No. 1251 . Bureau of Fisheries, 

 and No. 9255, Stanford University. It gives me greal pleasure to 

 name this superb troul for Theodore Roosevelt, in recognition of his 

 active interest in fish and game protection. 



This is the most beautiful of all the fronts; the brilliancy and 

 richness of its coloration are not equaled in any other known species; 

 the delicate golden olive of the head, back, and upper pari of the side, 

 the clear golden yellow along and below the lateral line, and thi 

 marvelously rich cadmium of the under parts fully entitle this species 

 to be known above all others as tJu Golden trout. In form it is no less 

 beautiful: its lines are perfect, the fins large and well proportioned, 

 and the caudal peduncle strong; all fitting it admirably for life in the 

 turbulent waters in which it dwells. It is a small fish, however. The 

 largest example collected by us was ll^/jt inches in total length and 

 the heaviest one weighed in ounces. It is probable that it never 

 attains a greater length than 14 inches or a weight of more than a 

 pound in Volcano Creek. 



The Golden trout is a native of Volcano Creek alone, and occurs 

 throughout the entire length of that stream. AVe caught specimen^ 

 at various places from above the tunnel to below the lowermost of 



the series of falls near the mouxh, and it was seen in all suitable pi; s 



from the tunnel 4g> the headwaters above Volcano Meadows, where the 

 elevation is more than 10.000 feet. Although the fish runs down 

 Volcano Creek even to fellow the lowest falls, it apparently does not 

 venture out into Kern River; no examples were seen there. It is a 

 creek fish and appears to keep within the peculiar environment of 

 the small stream. Although we obtained a specimen at the foot of
