274 Capt. Cautley on the Sevdlik Hills. 



dipping, on an average, 20° to the north. The topographical outline of these 

 mountains, shows a considerable southing of upheavement, in the hills west- 

 ward of the Jumna, as will be observed in the map* : and the circumstance of 

 the fossil remains abounding in the sandstones and clays in this tract, and not 

 in that between the Jumna and the Ganges, may probably be due to the non- 

 upheavement of the line on its prolongation eastward of the Jumna. The 

 drawings which accompany this paper f show that the action, in all proba- 

 bility, was exerted irregularly ; and although in the large scale we may lay 

 down the dip and direction with accuracy, the former as varying from 15° 

 to 33°, and the latter from N.E. to S.W., local details give very different 

 results. 



The sandstone rock, from which the fossil remains sent to the Society's 

 Museum were extracted, reposes at the above angle, over numberless beds of 

 clays, more or less rich in testaceous 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 circum- 

 stance 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 protects the fossil from destruction in its progress, as a boul- 

 der along the torrent'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. 



Carnivora - - Canine and feline. 



Ruminantia - - Elk — ox — deer in great varieties. 



SoUpeda - - - Horse.
