DISTRIBUTION OF ANIMALS IN AMERICA. 245 
far shorter road. Even a species of antelope and two 
other horned ruminants (Leptotherium) found their way 
to Brazil. Two sorts of tapir, of which the dentition, 
even in Cuvier’s eyes, is scarcely distinguishable from 
the Indian species; two species of pigs, still bearing 
in their milk-teeth unmistakable characters of their 
aboriginal form; and a number of deer, besides the 
lamas, a later and originally American offshoot of the 
Eocene Anoplotheria—are one and all living remnants 
of this ancient colony from the East, which did not 
reach its dwelling-place without copious losses on 
its long pilgrimage. It can scarcely be doubted that 
many of the beasts of prey which in the Diluvium of 
South America retained their family character more 
than they do now, must have arrived there in the same 
manner. Let us now remember that even the Eocene 
Cznopithecus of Egerkingen distinctly pointed to the 
present apes of America, and that the Didelphidz (Opos- 
sums) lie buried in the same European soils. It might 
almost appear that it was pre-eminently the division 
of arboreal quadrumana which, with the opossums, 
domesticated itself in the vast forests of their new abode, 
and, receiving a fresh impulse, gave rise to a multitude 
of special forms, without however having, even in the 
present times, reached the pitch of development 
attained by their cousins who had remained behind in 
the Old World. 
“We may now appropriately return to our previous 
remark that this migration of animals did not find the 
south of the New World destitute of mammals, but 
rather already occupied by the toothless representatives 
of antarctic, or at least of southern animal life. The
