418 CH@ROPOTA MUS. 
The tooth anterior to the grinders, and which from its 
shape Cuvier regarded as a canine, is situated closer to the 
symphysis of the jaw than in any of the existing Swide ; 
but the Peccari, in this respect also, comes nearest to the 
Cheropotamus. On the outer surface of the jaw, near its 
anterior extremity, the vascular foramina are as numerous 
as in the jaws of the Hog tribe. 
Nothing as yet is known of the incisors of the Chwropo- 
tamus; the rest of the dentition closely resembles that of 
the Peccari, but the premolars are more simple and the 
canines by their size, shape, and direction, and the lower 
jaw by the backward prolongation of its angle, alike mani- 
fest a marked approximation to the Ferine type. ‘The 
occasional carnivorous propensities of the common Hog are 
well known, and they correspond with the minor degree or 
resemblance, which this existing Pachyderm presents to 
the same type. The extinct Chwropotamus, still better 
adapted by its dentition for predaceous habits, presents an 
interesting example of one of those links, completing the 
chain of affinities, which the revolutions of the earth’s 
surface have interrupted, as it were, and for a time con- 
cealed from our view. 
It is interesting, also, to perceive that the living sub- 
genus of the Hog tribe which most resembles the Charopo- 
tamus should be confined to the South American continent, 
where the Llama and Tapir, the nearest living analogues of 
the Anoplotherian and Paleotherian associates of the Cha- 
ropotamus, now exist, and which was formerly inhabited 
by a genus — Macrauchenia, which connects the Llama 
with the Paleothere.
