The genus Dicotyles, embracing the peccaries, has been sufficiently indicated in the preceding 
article for my present purposes. Time will not allow me to go into any extended description of 
its essential peculiarities of form and dentition.

Sp. Ch —A white collar, more or less distinct, proceeding from the shoulders on each side of the neck. 
The preceding brief diagnosis, taken from Wagner, is sufficient to distinguish the collared 
peccary from the only other known species, the D. labiatus , in which the lower jaw is white and 
there is no white collar. The materials before me are not sufficient to furnish any satisfactory 
description of the external form of the animal, consisting only of two hides, without head and 
feet. For full details on the structure and habits of the species, I would refer to the admirable 
article on the quadrupeds of North America, as quoted above. 
The peccary has a much wider range in North America than is supposed by European syste¬ 
matic writers. It not only occurs through Mexico, hut even as far north in the United States 
as the Red river of Arkansas, in latitude 34°. Its western limit is not well ascertained, though 
it is said by some to occur in California.
