This species is so well known and has been so frequently described and 

 figured that no description is here needed. The best that has appeared is that 

 of Holbrook in the Ichthyology of South Carolina; in that, the only correct 

 account of the lingual dentition published by any American author, is given. 

 The best illustration of the species is given by Sonrel in Dr. Storer's " History 

 of the Fishes of Massachusetts," and is superior to that of Dr. Holbrook. 



Cuvier and Valenciennes have described the tongue as having asperities only 

 en its sides, while other naturalists have stated that the teeth on the tongue are 

 most obvious on its sides," or more correctly that the "tongue is rough at its 

 base and upon its sides and smooth in the centre." Dr. Holbrook has well said 

 that "there are two bands of minute teeth, at the root of the tongue, separated 

 slightly from each other in the mesial line ; the sides of the tongue are also 

 armed with small teeth." 



Prof. Filippi, a learned naturalist of Turin, has also correctly described the 

 lingual dentition of Roccus lineatus in comparison with a species of the 

 genus which he regarded as new, but which has, in this monograph, been con- 

 sidered as identical with the Roccus chrysops.

The Roccus chrysops of this monograph is undoubtedly identical with 

 the Perca or Lepibema chrysops of Rafinesque, and the Labrax multi- 

 lineatus of the " Histoire Naturelle des Poissons" and of Kirtland. The 

 descriptions that have been yet given of the species under those names are 

 meagre and unsatisfactory, but the notice of the color given bv the above
