152 ICHTHYOLOgiA OHIENSIS 



[<??] Supplement 



The Ichthyology of the River Ohio was begun to 

 be printed in the Western Review in December 1819, 

 ^nd has been continued gradually until November 

 1820. During the course of the impression some

 mouth toothed. Two dorsal fins, the first with

 has many affinities with the G. Holocentrus Lepomis, 

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

 secondary peculiarities distinguish it completely. 

 The name means Fountain-fish.

I have discovered this species in the summer of
