284 THEORY OF THE EARTH. 



Another species, of rarer occurrence, and pecu- 

 liar to more temperate climates (Rh. incisivus) *, 

 had incisors like our present rhinoceroses of the 

 East Indies, and, in particular, resembled that of 

 Sumatra f ; its distinctive characters are derived 

 from some differences in the form of the head. 



The third species (Rh. leptorhirius) had no 

 incisors, like the first and like the present rhino- 

 ceros of the Cape ; but it was distinguished by 

 a more pointed muzzle and more slender limbs J. 

 The bones of this species have been found more 

 especially in Italy, in the same strata with those 

 of elephants, mastodons, and hippopotami. 



There is a fourth species still (Rh. minutus), 

 furnished, like the second, with incisors, but of a 

 much smaller size, and scarcely larger than a 

 hog I). It was undoubtedly rare, for the remains 

 of it have only as yet been found in some places 

 in France. 



To those four genera of large pachydermata, is 

 added a Tapir, which equalled them in size, and 

 was consequently twice, perhaps three times, as
