tion ; but until recently he has been simply the illustrious 

 stranger, of whose good qualities we saw and acicnowledged, 

 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 professed ichthyologists have been at fault on this

MiGEATOEY Species. 

 The Salmon {Salmo salar, Lin.)

 The Sewin {S. Canibricus, 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-MianANTS. 

 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. salmulus, Will.) 



With respect to the latter, it has always been considered 

 to be the young of the sdmoa Mr Couch, however, classes
