THE SALMON FAMILY. 313 



THE COMMON TROUT. 



(Salmo fario *. ) 



With the Sea-Trout we conclude the list of the Silver 

 or migratory species of the genus Salmo f, and come to the 

 second division of that genus, viz. the Yellow or Golden, 

 non-migratory % Trout. 



DISTINGUISHING CHARACTERISTICS OF THE YELLOW 

 DIVISION OF TROUT. 



This group is at once distinguished from the last-named 

 by the difference in colour, a mark which, with the one occa- 

 sional exception in the case of the Sea-Trout, provided for 

 at p. 308-9, will generally prevent the possibility of any 

 confusion. It is also easily distinguished from the Charrs, 

 or Third Division, by the red and orange colours of the 

 latter, and by the additional characteristic of having two 

 complete rows of teeth on the vomer, whilst in the Charrs 

 the vomer has only a few teeth, and those on the most 

 forward part. 



* Salmo, a Salmon or Trout ; fario, the Trout, Lat. 

 t Salmon and Trouts properly so called J which never go down
