10. EUPOMOTIS. 
Eupomotis, GILL & JORDAN, Field and Forest, 1877, v. 2, p- 190. 
In the Journal de Physique, June, 1819, page 420,* Rafinesque first 
proposes the name Lepomis for the American Sunfishes, the type to be 
Labrus auritus of authors. The genus Lepomis he then proposes to 
divide into two subgenera, Pomotis and Apomotis, the former having the 
body rounded and the opercle auriculated, the latter having the body 
rounded or oblong and the operele without auricle. 
Of auriculated species, only one, auritus, is mentioned. This species 
is then obviously the type of Pomotis ; but it had been already indicated 
as the type of Lepomis. Pomotis then is typical Lepomis, and is a sim- 
ple synonym of the latter name. , 
In the Ichthyologia Ohiensis, in 1820, Rafinesque characteristically 
changed some of these names; Lepomis here becomes Icthelis, and 
Apomotis, Telipomis. Pomotis is still used in the same sense as before. 
In 1829, Cuvier and Valenciennes revived the name Pomotis of Rafi- 
nesque in precisely the same sense in which Rafinesque used it, but in- 
cluding several additional species. Cuvier does not credit the name 
Pomotis to Rafinesque, but, in accordance with a custom then as now 
too prevalent, in modifying the characters assigned to the genus, allowed 
his own name to supersede that of the earlier author. That Cuvier 
accepted the nanie Pomotis from Rafinesque is evident from the fact 
that he quotes Rafinesque’s descriptions in a foot-note. Pomotis and 
Bryttus of Cuvier and Valenciennes are practically equivalent to Po- 
*«613, Lepomis (Thoracique). Corps arrondi, ovale ou oblong, trés comprimé. Téte et 
opercules écailleux, ceux-ci mutiques, le postérieur flexueux, membraneux, quelquefois 
auriculé. Bouche petite, mAchoire & petits dents, lévre supérieure A peine extensible. 
Une nageoire dorsale ; nageoire thoracique 4 6 rayons dont 1 épineux sans appendices. 
Anus au milieu. Ce genre est nombreux en espéces, je’n connois 7 a 8 des Etats-Unis; 
son type est le Labrus auritus des auteurs, sous le nom duquel il y a 4 ou 5 espéces con- 
fondues. II différe particuliérement du Sparus par son opercule écailleux et le défaut 
d’appendice thoracique. I] se devise en deux sous-genre: 1. Pomotis. Corps arrondi, 
opercule auriculé. 2. Apomotis. Corps arrondi ou oblong, opercule sans auricule; mais 
tous ont le corps tacheté et une tache noire sur )’opercule. J’en ai découvert deux 
nouvelles espéces dans Ohio. 1. L. cyanellus. Corps oblong, tout couvert de points 
bleus, joues 4 lignes flexueuses bleues, opercule sans auricule; tache oblongue, queue 
bilobée. 2. ZL. macrochirus. Corps ovale, points bruns, point d’auricule; tache ob- 
longue, toute noire; pectorales trés longues atteignant l’anale; queue fourchée.”—
