SPECIES OF SALMON. 145 



tion ; but until recently lie has been simply the illustrious 

 stranger, of whose good qualities we saw and acknowledged, 

 but of whose history we were ignorant. We have been 

 guilty of such gross mistakes respecting this noble fish, 

 that, until a short time since, we were literally extirpating 

 the salmon from our rivers. Now, however, a better sys- 

 tem prevails under improved knowledge. Even now but 

 few fishermen can tell how many different species of this 

 magnificent and common fish there are in British waters. 

 Nay, even prof essed ichthyologists have been at fault on this 

 matter. Mr Garnell, in a comparatively late edition of his 

 work on " British Fishes," gives but six species, whereas the 

 best and latest work on the subject, " Couch's British 

 Fishes," gives us twelve good and distint species of salmon 

 and trout, as indigenous to the United Kingdom. They 

 are as follows : 



MIGRATORY SPECIES. 

 The Salmon (Salmo salar, Lin.) 

 The Salmon Peal which is the salmon trout of Yarrell, who haa

 The Sewin (S. Cambricus, Don.), which appears to be exclusively 

 confined to the rivers of the Welsh coast. 



The Sea Trout or Bull Trout (S. eriox, Lin.) 



The Salmon Trout (S. trutta, Lin.) 



The Slender Salmon (S. gracilis, Couch.) 



The Blue Pole (S, albres, Flem.) 



NON-MIGRANTS. 



The Lake Trout (S. ferox, Jard.) 

 The Common Trout (S. fario, Lin.) 

 The Gillaroo or Gizzard Trout. Thomson. Irish. 

 The Lochleven Trout (S. ccecifer, Parn.) Scotland. 

 The Parr (S. stimulus, Will.) 



With respect to the latter, it has always been considered 

 to be the young of the salmon. Mr Couch, however, classes
