On the Murex Corona. 29 1 



Ovibos ; a division which does not seem to be generally adopted 

 by subsequent naturalists. 



Under the name of Bos PaUasii, we would propose to 

 designate 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 

 extreme northern regions of Europe and America. In the 

 latter country, its remains have been found as low as 37° 

 north, as the locality of our specimen indicates. It was, 

 doubtless, allied in many particulars to the musk ox; but 

 from this, the observations of Cuvier, and the imperfect noti- 

 ces contained in the preceding remarks, show the great pro- 

 bability of its being specifically distinct.
