losophical latitude to the term. Even Ciivier, however, in the 

 latest edition of his great v^ork,* speaks of these two animals as 

 belonging to one genus. But, though they seem to have had 

 a somewhat similar form of the head, and the same number of 

 teeth, yet the great differences which are obvious in these, at 

 the first view, in their kind, their form, and their structure,t 

 render such an union forced and incongruous. 



The Megatherium and the Megalonyx have been found in 

 both North and South America. The former having been first 

 discovered in the southern continent, and the latter in the 

 northern, have become in a manner identified with these re- 

 spective localities, as peculiar to each of them; but they 

 appear, from what is now known, to have inhabited a region 

 extending for many degrees on each side of the equator.
