212 The Trouts of America 



The Nissuee or no-shee trout, — Salmo irideus stonei (Jordan). 

 The Golden trout of Mt. Whitney,— 



Salmo irideus agua bonita (Jordan). 

 The Long-headed trout of Lake Crescent, Wash., — 



Salmo bathxcetor (Meek). 



From this list it will be seen that we have 

 twenty-four forms of salmon-trouts in the waters 

 of North America, to which should be added three 

 imported species, — the brown or German trout, 

 Salmo fario, the Lock Leven trout, Salmo leve- 

 nensis, and the European sea-trout, Salmo trutta; 

 the latter has been recently introduced, but not to 

 a great extent. 



A few years ago the above forms of the cut- 

 throat were all known as Salmo mykiss, with vari- 

 ous subspecific names, and credit assigned to 

 Walbaum, as the first ichthyologist who classified 

 and named them ; but it has been found that the 

 true mykiss (a vernacular name, also called by the 

 natives "somka" and "salmon-trout") is confined 

 to the waters of Kamchatka, where it is said that 

 it differs from our native cut-throat by the ab- 

 sence of red slashes on the throat latch, and 

 by the small number of black spots sparsely 

 distributed on the body and fins. It is evi- 

 dently closely allied to the Atlantic sea-salmon,
