Observations. In the year 1820, Professits ES 
finesque published, in Lexington, Kentucky, his 
“Tehthyologia Ohiensis." As the circulation of this - 
volume has been very limited, and it cannot readily 
be procured, I have thought it advisable, whenever a 
genus of Rafinesque’s is referred to, to give its char- 
acters, that it may be recognised ; and shall, there- 
fore, pursue this course throughout this communica- 
tion, The genus Luxilus was established to re- 
ceive several species which it was thought advisable 
to separate from the genus Leuciscus BA": 
gated, somewhat compressed, with rather la rge x 
Vent posterior, or nearer to the tail. Head flat. zh
