On a Fossil Ox from the Mississippi. 327 



lers, who speak of their remains as occurring in great abundance. 

 From the fact of their having been found associated with re- 

 mains of the mastodon and deer, it is presumed that they were 

 co-existent with those species. 



The fourth species is the Bos moschatiis. From the testi- 

 mony of travellers already cited, it has been shewn that this spe- 

 cies formerly lived in the latitude of 40°, and even lower. It is 

 now confined within the limits of the Arctic Circle. They live 

 in herds, feed on lichens, leaves of the willow, and are fond of 

 mountainous rocky regions. The horns of the male, which are 

 larger than those of the female, sometimes weigh sixty pounds. 

 This species has been recently separated by Blainville, from the 

 genus Bos, and forms the new genus Ovibos ; a division which 

 does not seem to be generally adopted by subsequent natural- 

 ists. 



Under the name of Bos Pallasii, we would propose to desig- 

 nate the species to which we refer the fossil crania of Pallas and 

 Ozeretskovsky, and provisionally, the specimen from the banks 

 of the Mississippi, which has given rise to the preceding remarks. 



This animal was, as far as we know, an inhabitant of the ex- 

 treme northern regions of Europe and America. In the latter 

 country, its remains have been found as low as ST north, as the 

 locality of our specimen indicates. It was, doubtless, allied in 

 many particulars to the musk-ox ; but from this, the observa- 

 tions of Cuvier, and the imperfect notices contained in the pre- 

 <«ding remarks, shew the great probability of its being specifi- 

 cally distinct. 



III. On the identity of the Fossil Bones found in Georgia, United 

 States, with those of the Megatherium ef Paraguay. 



Mr Cooper, in a paper read to the Lyceum of Natural His- 

 tory of New York, January 1827, informs us, that, since a for- 

 mer communication on the subject of the Fossil Bones of Skida- 

 way Island, he had obtained, through the kindness of Dr Ha- 

 bersham, several other parts of the skeleton of the megatherium. 

 The collection last received consisted of numerous pieces, nearly 

 all fragments of the large bones of the extremities. They had 

 all marine shells adhering to them on the fractured surfaces, as 

 well as the others. Of these fragments, the author confines his
