The genus Eupomotis differs from Lepomis only in the blunter and 

 more pavement-like teeth of the lower pharangeal bones. These 

 bones are usually broader and more concave in Eupomotis than in 

 Lepomis, the gill rakers are usually shorter and less numerous, and 

 the supplemental maxillary is much reduced or wanting, and the 

 opercular flap is always provided with an orange spot on its lower 

 posterior border. The genus Xystroplites comprise the species of 

 Eupomotis with the larger mouth and the better developed supple- 

 mental bone and the longer, harder and more numerous gill rakers. 



A careful study of most of the species of this group, representing 

 a number of localities from Arkansas to Iowa, Ontario and Florida, 

 has led me to accept a slightly different arrangement from that 

 adopted by Jordan and Evermann, and so I add here a preliminary 

 revision of the entire group.
