The Loch Leven trout of Great Britain was introduced into 

 the United States from Scotland in 1885 and subsequent years. 

 It is somewhat closely related to the European brown trout, 

 Salmo fario, and has been artificially crossed with that 

 species in the United States, so that it is sometimes difficult to 

 find the pure bred Loch Levens in fish cultural establishments 

 at home. 



The body of the Loch Leven is more slender and elongate 

 than that of the brown trout, its greatest depth contained four 

 and one fourth to four and one half times in the total length 

 without caudal. Caudal peduncle slender, its least depth three 

 eighths of the greatest depth of the body, and equal to length 

 of snout and eye combined. The head is rather short and con- 

 ical, its length two ninths to one fifth of the total length without 

 caudal. The snout is one fourth or slightly more than one 

 fourth as long as the head. The interorbital space is somewhat 

 convex, its width equal to three fifths of the length of post- 

 orbital part of head. The eye is of moderate size, its long 

 diameter contained five and one half to six times in the length 

 of the head, and equaling about twice the greatest width of the
