300 On the Sevdlic Hills. [Oct. 



and become singularly conspicuous, by the weathering of some of the 

 ridges, when the mass of rock takes the appearance of huge spherical 

 concretions piled confusedly on each other. 



The organic remains of this sandstone yet brought to light, belong to 

 the following classes and genera : most of the species are new ; and 

 the appearance of totally undescribed forms will add very considerably 

 to our fossil genera. The new genera themselves will be the subject of 

 separate accounts in their proper place. 



Mammalia. 



Pac^?/£?em«?a... Mastodon — elephant — rhinoceros — hippopotamus — hog. 



Carnivora Canine and feline. 



jRuminantia Elk — ox — deer in great varieties. 



Solipeda Horse. 



Reptilia. 



.Gharial— crocodile ; both very closely corresponding 

 with the existing species now in the rivers. Lacer- 

 tine remains indeterminable. 

 Emys and tryonix ; some of the fragments are of the 

 most gigantic proportions. Of the smaller varieties, 

 nearly entire specimens have been found ; upper buck- 

 ler and carapax complete. My cabinet also contains 

 three heads, wanting only the occipital portion of the 

 cranium. 



Pisces. 



Genera not established. 

 Many other fragments have been found, but so imperfect as to render 

 a classification impossible. I may remark, that there appears to be no 

 end to the variety as well as quantity of these remains ; and we may ex- 

 pect to do much, even in this remote region, in advancing the inquiries 

 respecting fossil zoology. 



Of each genus above mentioned, with the exception of the horse and 

 the carnivora, I have already almost perfect skulls. The bones of the 

 body, however, appear to have been much broken and mutilated ; but 

 it is a singular fact, that from many places where the fossils have been 

 found as mere debris of fallen cliffs, fragments of bone have been obtain- 

 ed, which have admitted of being joined, although the fractured ends 

 were coated with carbonate of lime, as if they had been fossilized se- 

 parately. A beautiful example of this, is exhibited in an almost perfect 



Crocodilia.
