PAL^EOTHERIUM MEDIUM. Cuv. 

 The Middle-sized Paleothere. 



MOST of the Palseotherian fossils that have been col- 

 lected from the quarries of the hard freshwater marls of 

 the Isle of Wight, belong to the species called by Cuvier 

 Paleeotherium medium. This animal was about one sixth 

 smaller than the American Tapir, but stood higher on 

 its legs, and had longer and more delicate feet. The 

 grinding teeth are proportionally larger than in the Tapir. 

 In the specimen of the penultimate molar, (fig. Ill,) the 

 prominent angles formed by the coronal border of the 

 enamel which covers the outer depressions of the tooth, 

 are more marked than in the molar of the Palaotlierium 

 magnum, but this is owing to the crown being more deeply 

 worn, which has also reduced the posterior fold (a) to its 

 insular form : a small portion, however, of this part of the 

 grinder is broken away in the specimen. The inner prin- 

 cipal fold (5) retains its peninsular character.
