This fish is a true Pearch, though its form, elongated mouth, and 

 fiercely predatory habits suggest the idea of a Pike, whence Dr. De- 

 Kay has given it the appellation of Pike Pearch, which is a translation 

 of its classical name, in preference to the name Sandre, which belongs 

 to the Canadian fish of the same species, and to the analogous Euro- 

 pean fishes.
