This genus, as understood by us, is very closely related to Lepomis, 

 differing only in the blunter and more pavement-like teeth of the lower 

 pharyngeal bones. These bones are, in typical species^ broad and con- 

 cave, especially in the adult. There is considerable variation among the 

 species, and it is possible that this division can not be maintained. Most 

 of the species have long pectoral fins, the supplemental maxillary lost 

 or very much reduced, and the opercular flap always with an orange 

 patch on its lower posterior portion. Gill rakers various, usually short. 

 The retention of this genus is possibly justified by convenience, but 

 neither the longer pectorals nor the blunt pharyngeals separate it sharply 

 from Lepomis, with which it has been united by McKay, Bollman, and 

 Jordan & Gilbert. (et>, well; TTW/^O, opercle ; ovs, ear; or rather, ev, gen-

XYSTROPLITES (bvvrpov, scraper; oTrAmjs, armature, from the gill rakers of the typical species): 



a. Pectorals shorter than head, not extending beyond tips of ventrals; scales small, about 42; 



gill rakers rather long; coloration plain. PALLIDUS, 1404. 



EUPOMOTIS: 



aa. Pectorals longer than head, extending to beyond front of anal; gill rakers moderate or 



short; opercular flap orange on its lower posterior portion. 

 6. Cheeks without marked blue or orange spots or lines. 



c. Scales large, 34 to 39; opercular flap smaller than eye, its margin blood-red in 



male. HEROS, 1405. 



cc. Scales moderate, 42 to 44; opercular flap broad, with a very broad orange or 



whitish margin. 



d. Cheeks with 5 rows of scales; color chiefly greenish. HOLBROOKI, 1406. 



dd. Cheeks with 6 or 7 rows of scales. EURYORUS, 1407. 



bb. Cheeks with wavy blue lines; sides of body profusely spotted with orange; scales about 

 47; dorsal spines not very low; opercular flap large, its lower posterior border 

 always scarlet. GIBBOSUS, 1408. 



Submenus XYSTROPLITES, Jordan. 

 1404. EUPOMOTIS PALLIDUS,* (Agaasiz). 



Head 2| ; depth 2| ; eye 4 J snout 3 ; scales 8-42-12, 5 rows on cheek. 

 D. X, 10 ; A. Ill, 9. Body elongate, rather deep mesially . Caudal pedun- 



* " This species resembles Pomotis incisor (Lepomis pallidm) in the outline of the body, the nature 

 and coloration of the scales, and in the size and form of the fins, but it differs greatly from it by 

 its large mouth, the free extremity of the upper jaws reaching the vertical line of the middle of 

 the eye, by the presence of teeth upon the palate, and by the ventral fins being placed immedi- 

 ately under the pectorals. The black opercular appendage, which is very short, has a narrow
