THE AZUBINE. 



{Leuciscus cwuleus *.) 



The Azurine, which was first added to the British list 

 by Yarrell, is, in England, found only in a few localities in 

 the neighbourhood of Knowsley, the seat of Lord Derby, 

 by whom the specimens from which the engraving is taken 

 were supplied. 



It is very hardy and tenacious of life, and its flesh is 

 said to be firm and of good flavour. In its food, and in 

 the baits used for its capture, it resembles the Carp ; and 

 the largest specimen known to have been taken was not
