314 THE ANGLER-NATURALIST. 



Of the Yellow Trout there are only three generally re- 

 cognized species in this country — though probably there 

 exist others yet to be verified. 



The admitted species are — 



The Common Trout [Salmo fario) ; 



The Great Lake Trout {Salmo ferox) ; and 



The Lochleven Trout {Salmo Levenensis) . 



In regard to each of these, the specific characteristics 

 are given m detail at the end of the several notices ; but a 

 few general observations here will enable the reader to 

 distinguish them without the necessity of resorting to a 

 minute comparison. 



We have not in the present case the same prominent 

 differences in the shape of the gill-covers and position of 

 the teeth by which the migratory Trout and Salmon are so 

 clearly defined, and for ready points of distinction we must 

 rely upon colour, general appearance, and localities ; these, 

 however, will be found amply sufiicient for the purpose. 



1. As regards localities. — The Common Yellow Trout 



breeds indifferently in brooks, rivers, and lakes, whilst 

 the Great Lake Trout is never found except in or close 

 to lakes (generally large and deep) ; and the Lochleven 

 Trout is confined, so far as we are aware, to Loch 

 Leven itself and one or two other lochs and lakes in 

 the county of Sutherland. 



2. Colour. — The Lochleven Trout has never any crimson 



spots on the body, whilst the Common Trout is never, 

 or hardly ever, without them ; and in the Great Lake
