BEARDSLEE TROUT. 



In Crescent Lake, Admiral Beardslee also discovered the Beardslee 

 trout, to which his name has been given. It is found in deeper water 

 than the Crescent trout, and it is larger, some specimens weighing from 

 ten to fourteen pounds. Its color is deep blue, dotted with small black 

 spots. The scales are as large as in the Rainbow trout, about one 

 hundred and thirty in a lengthwise series, and the head is long, making 

 more than one fourth the total length to the base of the caudal. This 

 is one of the finest trout known in any country, and it should be planted 

 in other deep lakes before it is exterminated by the trout-hog, who is 

 already encamped on the shores of Lake Crescent. 



Another trout has been described from Lake Crescent as Salmo 

 bathaecetor (Meek), It is certainly much like the Crescent trout, of 

 which it would seem to be a deep-water variation. Near to Lake

BEARDSLEE TROUT— Salmo btardsleii Jordan and Seale. 



Crescent, but wholly separated from it, is another mountain lake called 

 Lake Southerland. In this lake two other species or forms of trout 

 are found, the one called Salmo jordani being close to Salmo clarkii, 

 the other Salmo declivifrons, resembling Salmo crescentis. Doubtless 

 other mountain lakes of the Olympic range will yield still other species 

 of trout isolated from the body of their kind and at least on the road 

 to becoming separate species. The origin of each of the different 

 species of trout is clearly to be traced to the condition of isolation. 



STEELHEAD TROUT. 



In the coastwise streams from Skagway, in Alaska, to Santa Barbara, 

 California, is found a fine, large trout, known as the Steelhead, its 

 scientific name being Salmo rivularis. This name was given by Dr. 

 W. 0. Ayres to a specimen taken in the Sacramento River, at Martinez. 

 The species was long known as Salmo gairdneri, but the specimen 

 originally named by Dr. Richardson for Dr. Gairdner was a young
