TERTIARY SERIES. 
The nearest approach among living animals 
to the form of these extinct aquatic quadrupeds, 
is found in the Tapirs that inhabit the warm 
regions of South America, Malacca, and Su- 
matra, and in the Daman of Africa. 
It is not easy to find a more eloquent and 
striking acknowledgment of the regularity and 
constancy of the systematic contrivances that 
pervade the animal remains of the fossil world, 
than is contained in Cuvier’s Introduction to his 
account of the bones discovered in the gypsum 
tarsus is like that of the camel. The place of this genus stands, 
in one respect, between the rhinoceros and the horse ; and in 
another, between the hippopotamus, the hog, and the camel. 
Lophiodon. 
The Lophiodon is another lost genus, allied most nearly to the 
tapir and rhinoceros, and, in some respects, to the hippopotamus, 
and connected closely with the Paleeotherium and Anoplothe- 
rium. Fifteen species of Lophiodon have been ascertained. 
Anthracotherium. 
The genus Anthracotherium was so called from its having; 
been first discovered in the Tertiary coal, or Lignite of Cadibona 
in Liguria : it presents seven species, some of them approximat- 
ing to the size and character of the hog ; others approaching 
nearly to that of a hippopotamus. 
Cheropotamiis. 
The Cheropotamiis was an animal most nearly allied to the 
hogs; in some respects approaching the Babiroussa, and forming 
a link between the Anoplotherium and the Peccary. 
Adapis. 
Tlie last of the extinct Pachydermata found in the gypsutf 
quarries of Montmartre, is the Adapis. The form of this crea- 
ture most nearly resembled that of a hedgehog, but it w’as three 
times the size of that animal ; it seems to have formed a linl^ 
connecting the Pachydermata with the Insectivorous Carnivora.
