PALAOTHERIUM MEDIUM. Cuv. 
The Middle-sized Paleothere. 
Mosr of the Palotherian 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 
Paleotherium 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. 111,) 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 Paleotherium 
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 mner prin- 
cipal fold (4) retains its peninsular character.
