rr^HE Sewen is a species closely allied to the Salmon Trout ; it occurs chiefly in Wales, 

 -■- and hence it was named cambricus by Donovan, who has g-iven a tolerable figure of this 

 fish in its grilse state ; it is also found in the rivers of the South of England, as in Devon- 

 shire and Cornwall, and is said to occur in Ireland. There are continental specimens in the 

 British Museum from Denmark, Norway, and Jutland. In the South of England this fish is 

 known to the angler as the Peal or Salmon-Peal, which terms in Scotland are also applied to 

 the Salmon Trout. Like this last-named species, the Sewen is migratory in its habits, 

 ascending rivers from the sea for the purpose of depositing its spawn. In colouration this fish 

 is subject to considerable variety, more so, I think, than occurs in any other migratory Sal- 

 monoid. When taken fresh from the salt water, or from an estuary, or indeed from a river, 

 if it has not long sojourned therein, the colour is a beautiful blue, and greenish on the head
