ME. VAIT VOORST having kindly placed the illustrations of the 

 late Mr. YarrelTs magnificent " History of British Fishes" at the 

 Author's disposal, they have been gladly made use of in the 

 great majority of instances throughout the following pages. 



Most of these engravings were executed under Mr. YarrelTs 

 immediate superintendence during a lengthened term of observa- 

 tion ; and it was felt, therefore, that it would be difficult, if not 

 impossible, to supply equally perfect and reliable designs within 

 any available period.
