CATALOGUE OF SPECIES OF CENTEARCHID^. 



I give below a catalogue of the species of Centrarchidce, which appear 

 to be valid, with their geographical distribution. Those of which I have 

 not been able to examine specimens are indicated by a star (*). Several 

 species, as Lepomis oplithalmicus Cope, Bryttus humilis Grd., are known 

 only from specimens too immature for me at least to come to any cer- 

 tain conclusion as to their true relations. 



The type-species of each genus is placed first ; d. s. indicates doubt- 

 ful species ; d. g.^ doubt as to whether placed in the proper genus.
