or pterygoids; pharyngeal bones narrow or broad, with sharp or blunt paved teeth; 

 preopereular margin entire; opercle ending in a more or less elongated flap which is 

 conspicuously colored; gill rakers usually short and feeble; dorsal spines, 10; anal 

 spines, 3; caudal fin concave or emarginate behind; pectorals long or short, pointed 

 or rounded. 



Forbes and Richardson 1 say: 



The genus Lepomis, as here understood , includes Apomotis of various authors. The 

 forms that have been known under these two names agree in their pharyngeal denti- 

 tion, which is remarkably different from that of the genus Eupomotis. The fact that 

 the opercular flap is usually either entirely black or black with a definite border above, 

 behind, and below serves as a useful distinction of the species of this genus from the 

 single commonly distributed species of Eupomotis (E. gibbosus), in which there is 

 always a conspicuous roundish spot of red at the lower posterior corner of the opercular 

 flap. 



In a footnote on the same page they add: 



We have not found the "complete gradation in the character of pharyngeals between 

 Lepomis * * * and Eupomotis, both as to the width and form of the bones them- 

 selves and the form of the teeth" that was described by McKay (Proc. U. S. Nat. 

 Mus., vol. 4, 1881, p. 88). (See Richardson, 1904, Bull. 111. State Lab. Nat. Hist., 

 vol. 7, pp. 27-32.) 



Also on page 259 under genus Eupomotis: 



Form as in Lepomis; mouth always small ; no supplemental maxillary bone and no 

 teeth on palatines; lower pharyngeals deep and broad, with inferior and lateral 

 prominences, the width of the toothed portion about 2 in its length ; pharyngeal teeth 

 short with the upper surfaces bluntly rounded or paved (truncate); gill-rakers short; 

 fins rather long; red color on opercular flap in typical species forming a roundish 

 spot. Eastern United States and Canada; 3 species. 



Meek and Hildebrand 2 adopt the generic diagnosis of Forbes and 



Richardson.
