to which their stomach, divided into several sacs, evidently allies 
them. It is singular that the aorta of these animals is often found 
very much enlarged, but at different parts of it, as though they were 
subject toa kind of aneurism. 
Only two species are known, both feotn South America, which 
were ascertained by Azzara: Linnzus confounds them under the 
name of Sus tajassu. 
Dic. torquatus, Cuy.; Buff. X, iii and iv. (The Patira.) Hair 
annulated with grey and brown; a whitish collar, stretching 
obliquely from the angle of the lower jaw over the shoulder ; ; 
half the size of the Wild Hog. 
Dic. labiatus, Cuv.; the Tagniacati, Taitetou, Tajassou, &c.; 
larger, brown, and with white lips. 
Here may come a genus now unknown in the living crea- 
tion, which we have discovered, and named 
ANOPLOTHERIUM. 
It presents the most singular affinities with the various tribes of 
the Pachydermata, and approximates in some respects to the 
order of the Ruminantia. Six incisors to each jaw, four canini 
almost like the incisors, and not projecting beyond them, and 
seven molars throughout, form a continuous series without any in- 
tervening space, a disposition of the teeth seen in Man only. The 
four posterior molars of each side are similar to those of the Rhino- 
ceros, the Daman, and the Palzotherium; that is, they are square 
above, and form double or triple crescents below. Their feet, ter- 
minated by two great toes, as in the Ruminantia, differ in this—the 
bones of the metatarsus and metacarpus always remain separate, or 
without being soldered together. The composition of their tarsus 
is the same as in the Camel. 
The bones of this genus have hitherto only been found in the 
gypsum quarries near Paris. We have already ascertained five 
species: one the size of a small Ass, with the low form and 
long tail of the Otter—.2. commune, Cuv., to the internal edge 
of whose fore foot was affixed a small accessary toe: another of 
the size and light carriage of the Gazelle—/. medium: a third 
of the size, and about the proportions of the Hare, with two 
small accessory toes to the sides of the hind feet, &c. See
