The Roccus chrysops thus described is undoubtedly identic 

 Lcpibcma chrysops of Rafinesque, and the Labrax muttilitteatus of 



relle des Poissons" and of Kirtland. The descriptions that ha 1 

 species under those names are meager and unsatisfactory : but tl 

 given by the above-named authors, and the possession of spec: 

 hydrographical basins as those from which the fishes described 

 leave no doubt as to the identity of the species. 



Rafinesquc's description of his Perca chrysops is, like almos 

 inapplicable to any known fish, but it agrees with the Morone chr 

 other species. Rafinesque erroneously attributes to his specif 

 rays, a single opercular spine, eight spines to the first dorsal fin
