THE SALMON FAMILY. 343 



tages in the number of specimens at his command^ and has 

 consequently deduced his arguments and conclusions from 

 a direct examination of the fish themselves, without being 

 compelled, as most previous ichthyologists have been, to 

 depend in a great measure upon the confused and often 

 incorrect descriptions of other writers. He has, moreover, 

 taken the trouble to collect and sift the opinions and 

 statements of all previous authorities entitled to be con- 

 sidered as such, and has pointed out where their arguments 

 or conclusions are defective. 



The substance of his examinations has been embodied in 

 a comprehensive treatise, from which I shall here present 

 my readers merely with the results. 



Three distinct species of Charrs, then, have been distin- 

 guished by Dr. Giinther as inhabiting different localities in 

 the British Islands *. These are — 



1. The Welsh Charr, or Torgoch of Llanberris {Salmo 



Cambricus f) . 



2. The Windermere Charr {Salmo Willughbii J). 



3. The Grey Charr, or Fresh-water Herring of Lough 



Melvin, Ireland {Salmo Grayi §) . 



* Since tlie above was put into type I have been favoured by 

 Di'. Giintber witb a further paper on the British Charr, in which he 

 adds two more species to the list, viz. Salmo alpinus (the Northern 

 Charr), found in Lake Helier, Hoy, Orkneys, and probably in other 

 Scotch waters; and Salmo Colii, found in Loughs Esk and Dan, 

 Ireland.
