OF GREAT BRITAIN. 143 



The Chub is tolerably equally distributed 

 throughout most parts of the United Kingdom. 

 It is the Penci or Cochgangcn of Wales, and the 

 Skclly of Scotland and of the Cumberland lakes, 

 though by no means to be confounded with the 

 Ulswater Schelly or Givyniad. The Chevin is also 

 another local name for the Chub.
