FAUNA ANTIQUA SIVALENSIS. 



The sandstone rock, from wMcli the fossil remains sent to 

 the Society's Miisevim were extracted, reposes at the above 

 angle, over numberless beds of clays, more or less rich in tes- 

 taceous remains. The fossil bones lie in great abundance on 

 the surface of the slopes in the neighbourhood of the sand- 

 stone, amongst the ruins of fallen cliffs, in the beds of water- 

 courses, &c. The bones which we have had the good fortune 

 to dig out of the rock are perfectly sharp, and in all their 

 original perfection. I may here advert to a circumstance to 

 which the preservation of the water- worn specimens is chiefly 

 due. The sandstone is generally soft, but in the proximity of 

 the fossils it becomes ferruginous, concretionary, and so hard 

 as to turn the edge of the chisel ; and thus it protects the fossil 

 from destruction in its progress, as a boulder along the tor- 

 rent's bed. These concretions are occasionally globular, 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. 



Pachydermata . . Mastodon, elephant, rhinoceros, hippopotamus, hog. 



Carnivm-a . . . Canine and feline. 



Huminantia . . . Elk, ox, deer in great varieties. 



Solipeda .... Horse.
