RAFINESQUE ON OHIO FISHES. 739 



A third paper, in the November number of the same journal is called 

 " Further account of Discoveries in Natural History in the Western States, 

 by Constantine Samuel Rafinesque, Esq. Communicated in a letter 

 from that gentleman to the editor, Lexington, October 5, 1818." 



In this are described the following new species, and the genera to 

 which they belong :

A fourth paper by Rafinesque on Ohio animals was published in the 

 Journal de Physique, de Chymie et d'Histoire Naturelle, Paris, June, 

 1819. It is entitled " Prodrome de 70 nouveaux Genres d'Animaux 

 d6couverts dans I'int^rieur des Etats-Unis d'Amerique diirant I'an^e

The fifth paper by Rafinesque on Ohio Pishes is " Description of the 

 Silures or Cat-fishes of the River Ohio, by C. S. Rafinesque, Professor of 

 Botany in the Transylvania University of Lexington, Kentucky," from 

 Quarterly Journal of Science, Literature and Arts, Royal Institution, 

 London, 1820, ix. 



Here are described the following species. 



Silurus maculatuB, Silurus cerulesoens, SUurus lividus, 

 var. erythroptera, var. melanurus, var. fuscatus,

var. marginatus, Silurus uebulosns, Silurus capreus, 



var. lateralis, Silurus visoosus, Silurua xanthooephalus, 



var. leuooptera, Silurus limosus. 



Rafinesque now desired to gather together these scattered papers, with 

 their confused and often contradictory nomenclature into one coherent 

 work, and so he began the publication of a series of descriptions of the 

 fishes of the Ohio River in the " Western Review and Miscellaneous 

 Magazine," published at Lexington, Kentucky. This publication 

 began December, 1819 and closed November, 1820. 



Oversheets of this series of articles were bound and repaged as a small 

 volume under the following title :
