152 ICHTHYOLOGIA OHIENSIS 



\S5'\ Supplement 



The Ichthyology of the River Ohio was begun to 

 be printed in the Western Review in December 1819, 

 and has been continued gradually until November 

 1820. During the course of the impression some 

 new species have been discovered, or ascertained, 

 which I now propose to notice. 



THORACIC FISHES. 

 XXXVI Genus. Springfish. Pegedictis. Pegedicte.

 membranaceous appendage and a concealed spine, 

 mouth toothed. Two dorsal fins, the first 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. Holocentriis Lepomis, 

 Etheostonia, &c. but its conical form and many other 

 secondary peculiarities distinguish it completely. 

 The name means Fountain-fish. 



105th Species. Catseye Springfish. Pegedictis 

 ictalops. Pegedicte aeuil de chat. 



Jaws equal, forehead knobby, eyes elliptical. 

 Body olivaceous with some black transversal unequal 

 brown bands; a concealed spine on the gill cover: 

 lateral line straight: tail elliptical. The first dorsal 

 fin with 8 rays, the second with 12, as well as the 

 anal and pectoral fins. 



I have discovered this species in the summer of
