In addition to the genus Squalus, the isolated frag- 

 ments of other cartilaginous fishes, as the Raia and Aci- 

 penser, are occasionally found in similar localities as 

 the former. 



Fishes proper. 



The fossil bones of fishes hitherto discovered in the 

 United States, belong principally to Cuviers second di- 

 vision, or 



Malacopterygia, 



Including among others the carp and the gar. On 

 the 24th of January 1825, the author of these remarks 

 had the pleasure to be present at the reading of an es- 

 say by Dr. Dekay, before the New York Lyceum of 

 Nat. History, on the u Fossil fish of the U. States f 9 

 this essay we believe has never yet been published, but 

 we were impressed at the time by the following state- 

 ment of Dr. Dekay : " All the fossil fish which I have 

 examined in the United States, are modelled after the 

 Esox osseus, or bony-scaled pike of the Mississippi" 

 which last species then, he thinks may stand, " as the 

 representative of a former creation, — the Logans of 

 their race." This carious fact was subsequently con- 

 firmed by the observations of Baron Cuvier — vid. " Os- 

 semens Fossiles."
