288 Zoological Writings of Rafinesque. 
moins i] est du devoir de ceux qui ont verifié et constaté les faits 
réels qui les détruisent, de chercher a les divulger et a éclairer la 
domaine des sciences. .... Il est plus facile de copies des erreurs, 
que de rechercher la vérité, et qnand elle est découverte, elle a 
souvent bien de la peine a percer les nuages de l’ignorance ou des 
préjugés scientifiques.” : 
emarques sur trois erreurs ichthyologiques. “The first is the 
absurd division of fishes into osseous and cartilaginous ;” the se- 
cond, that authors consider the Pleuronectes as thoracic instead 
of jugular; and the third, that the prepared fish roe called botargo, 
does not belong to the Mugil, but to the Tunny. 
Sur quelques animaux hybrides. This apocryphal account, 
(founded upon hearsay, ) relates to such animals as Felis domes- 
tiea, Didelphis Virginianus; and Procyon Vulpes. 
Sur le genre Manis, et description d’une nouvelle espece. Three 
species (two of which are Linnean) are described under two sub- 
genera, which, with changing specific names, has enabled our 
author to append his name to them all! 
Western Review. Several articles are inserted heey but we can 
only mention the Canis leucurus, a white tailed fox of Kentucky: 
1819. Twenty four lectures on the natural history of the Uni- 
verse, the earth and mankind, animals and plants. (MS.) These 
unpublished lectures are in our possession ; they treat of astrono- 
my, meteorology, geology, mineralogy, crystallography, &c. Nine 
of them constitute the zoological portion, and indicate but little 
talent. The introductories are good, and those devoted to Ameti- 
can geology amusing, from the singularity of the views advanced. 
1820. Fchthyolighs Ohiensis, one vol. 8vo., pp. 90. Oue hun- 
dred and eleven species are described. It is a valuable contribu- 
tion to this branch of science, and Prof. Kirtland’s labors in the 
same field will rendera particular notice unnecessary. He very 
properly separates the broad-mouthed, from the narrow-mouthed 
Lepidostei. 
Fishes of the Susquehanna. (Unpublished MS.) The de- 
scriptions are too short to enable one to make out all the species ; 
and, as usual with our author, species are multiplied on the 
strength of the locality. “Perea interrupta, Raf.” is Labrax lin- 
eatus, Lin. ; Esox chlorops = reticulatus, Les. ; and Luxilus ver- 
rucosus, is probably Cyprinus cornutus, Mitch. Thirty seven 
species are described, and thirteen are certainly omitted, which 
gives fifty species to the Susquehanna. Among the omissions
