Eupomotis (Jill & Jordan. 



Lower pharyngeals deep and broad, with inferior and lat- 

 eral prominences, never flattened or hollowed out underneath 

 as in Lepomis; width in length of toothed portion about 2 in 

 adults; inner angle 95° to 111°; outer margin a double curve, 

 moderately inbent posteriorly, in front of spur, and more or less 

 decidedly rounded anteriorly, as the margin of a lateral ledge- 

 like prominence; teeth on lower pharyngeals short and heavy, 

 their upper surfaces very bluntly rounded or paved. Red or orange 

 on posterior portion of opercular flap definitely marked off from 

 the paler or blackish portions adjacent, and not blended with 

 them as in the preceding genus. Body more or less compressed 

 and back elevated. Mouth rather small; no supplemental max- 

 illary bone and no teeth on palatines. Gill-rakers always short, 

 sometimes very much reduced. Pectoral fins always longer 

 than head, sometimes extending past middle of anal. Dorsal 

 spines rather higher than in most species of Lepomis. T\\n 

 species found in Illinois.
