The Itchthyology of the River Ohio was begun to be printed 

 in the Wcatcrn Review in December 1819, and has been con- 

 tinued gradually until November 1820. During the course of 

 the impression some new species have been discovered, or as- 

 certained, which I now propose to notice. 



THORACIC FISHES. 



XXXVI Genus. Springfish. PepxEdictis. Pegedicte. 



Body conical with small scales, belly flat, vent medial. Head 

 broad scaleless, gill cover with a membranaceous appendage 

 and a concealed spine, mouth toothed. Two dorsal fins, the 

 iirst with simple, soft, semi-spinescent rays. Thoracic fins 

 ■with five rays. 



This new genus belongs to the family Percidia, and has many 

 affinities with the G. Holocentrus Lepomia, Ethcoatoma^ Sec. 

 but its conical form and many other secondary peculiarities dis- 

 tinguish it completely. The name means Fountain-fish. 



105th Species. Catseye Springfish. Pegedictis ictalops, 

 Pegedicte seuil de chat. 



Jaws equal, forehead knobby, eyes elliptical. Body oliva- 

 ceous with some black transversal unequal brown bands; a con- 

 cealed spine on the gill cover: lateral line straight: tail ellipti- 

 cal. The first dorsal fin with 8 rays, the second wivii 12, as 

 well as the anal and pectoral fins. 



I have discovered this species in the summer of 1820 near 

 Lexington. It has no vulgar name. Length hardly two inch- 

 es. Head large brown, convex above witl^ several small knobs 

 on the forehead, fiut beneath. Eyes as in the Catfishes with ob- 

 long eyes, iris gilt brown. Spine of the gill cover coficealed 

 iinder the skin. Teeth small and acute. Pectoral fins large 

 lanceolate. Btlly white and flat. Fins hyalin with some brown 

 spots. Five transversal bands. The specific name means Cats- 

 eye. 



6lh Genus. Etheostoma. 



I06th Species. Springs Hogfish. JEtheostoma fontinalis, 

 Etheostome des fcntaincs. 



Body ot^long cylindrical, breadth one sixth of the length, oH- 

 vaceous, sides with transversal brown lines somewhat curved: 

 a small round black spot behind the gill cover; latv;ral line ob*. 

 solcle. Jaws obtuse, the upper one shorter. Tail oboval en- 

 tire gilt tesselated with black. First dorsal with 8 rays, the se- 

 cond and anal with 12. 



A little species, from one to two inches long, found in the 

 springis and caves near Lexington in the summer. It belongs 

 to the subgenus Difilesion. Body cylindrical somewhat com- 

 pressed. Head small flat above: gill coyer attenuated behin^
