 cans have added steelhead, hardhead, and salmon- 

 trout. 



During the last decade ichthyic research has 

 been very active in the waters of the Pacific 

 slope, and in addition to radical changes in the 

 technical nomenclature of the salmon-trouts, two 

 new species have come to light, and one of the 

 charr-trouts of Eastern waters hitherto strange 

 to science has been differentiated and classified : 

 these new species will be described on subsequent 

 pages. 



For many years there was known but one 

 subspecific form of the steelhead series, the Kam- 

 loops trout {Salmo gairdneri kamloops). This is 

 a fine large fish, doubtless intergrading with the 

 typical steelhead, but differing from it in habits, 

 coloration, and in form. It is landlocked, and, 

 so far as is known of its habitat, is confined to 

 the lakes of British Columbia, particularly lakes 

 Kamloop, Okanogan, Kootenay, and other lakes 

 tributary to the Fraser River or to the Upper 

 Columbia. In form it is slender and graceful,
