122 SALMONID.E. 



salvelinus, and salmarinus of Linnaeus as different states 

 only of the same fish.* 



Examples of the Charr of the Northern lakes of England 

 agree exactly with the description and figure of the Ombre 

 Chevalier in M. J urine's paper on the fishes of Lake Leman, 

 Geneva. 



In the former edition of this work I considered the Welsh 

 Charr distinct as a species from the Northern Charr, but I 

 have now reason to believe that I had not made sufficient 

 allowance for the variations in appearance produced by local 

 influence, as mentioned under the head of Common Trout, at 

 page 97 ; and, assisted by the published notes of W. Thomp- 

 son, Esq. of Belfast (An. Nat. Hist. vol. vi. p. 439), I am now 

 induced to consider as one species the Charr of England, 

 Scotland, Ireland, and Wales, and that our fish is also the 

 same species as that found in Germany, in the lakes of Swit- 

 zerland, and also those of Scandinavia. 



Mr. Thompson precedes his notes by the following re- 

 marks : " The chief object of my inquiry was to learn 

 whether in the lakes of Ireland, and in those of Scotland, 

 from which I could procure specimens, the S. salvelinus of 

 Donovan was to be found ; and at the same time to ascer- 

 tain, at least for my own satisfaction, whether its characters 

 have sufficient permanency to entitle it to rank as a distinct 

 species. As they are merely crude unfinished notes that are 

 to follow, I shall here give the result of the investigation, 

 that the reader may be in possession of it without entering 

 into the details. In a fresh state I have had the opportunity 

 of examining Charr from three localities, Windermere (Eng- 

 land), Lough Melvin (Ireland), and Loch Grannoch (Scot- 

 land) ; and, either in spirits or preserved dry, from nine other 

 lakes in Ireland and Scotland. The examination of these
