Class IV. CHARR SALMON. 413 



lower part of the body, tinged with red. The 

 lateral line strait, dividing the fish into two equal 

 parts, or nearly so. 



The jaws of the Case Charr were perfectly 

 even ; on the contrary, those of the Red Charr 

 were unequal, the upper jaw being the broad- 

 est, and the teeth hung over the lower, as might 

 be perceived on passing the finger over them. 



The branchiostegous rays were, on different 

 sides of the same fish, unequal in number, viz. 

 12,-11, 11,-10, 10,-9, except in one, where 

 they were 11,-11. 



The Gelt, or Barren Charr, was rather more Gelt 

 slender than the others, as being without spawn. 

 The back of a glossy dusky blue ; the sides sil- 

 very, mixed with blue, spotted with pale red ; 

 the sides of the belly were of a pale red, the 

 bottom white. 



The tails of each bifurcated. 



The charrs we have seen, brought from Snow- 

 don lakes, were rather smaller than those of 

 Westmoreland, their colors paler. The sup- 

 posed males very much resemble the Gelt 

 Charr ; but that is not a certain distinction of 

 sex, for the Rev. Mr. Farrington* has told me 

 that the fishermen do not make that distinction.
