2a subgenus, POMOTIS. (p. 28.) 



9th species, Red-Eye Sunfish, ICTHELIS ERYTHROPS, Icthele ceuil- 

 rouge. (p. 29.) 



Amploplites eupestbis (Raf.) Gill. 

 Bodianus rupestris Rafinesque, 1818. 



Description fair. The name Fomotis, first proposed in 181,9, is a mere 

 synonym of Lepomis. 



* 10th species, Eared Sunfish, ICTHELIS AURITA, Icthele oreilleuse. 



Xenotis lythkochloris Jordan, nom. sp. nov. 

 Not Fomotis auritus ("L.") Giinther. 

 = Lepomis auritus Cope. (Not of Raf. 1818.)

(p. 29.) 



Xenotis megalotis (Raf.) Jordan. 



Fomotis nitidus Kirtland. 

 Not Ichthelis incisor (C. & V.) Holbr. 

 Not Lepomis megalotis Cope,

Description pretty good. This cannot be the Lepiopomus pallidus {in- 

 cisor), as has been supposed by Professor Cope. 



V. Genus, RIVER-BASS, LEPOMIS, Lepome. (p. 30.) 



= Micropterus Lacepede. 

 Not Lepomis Raf., 1819.
