156 MAMMALIA. 
each of their cheeks hangs a thick fleshy lobe, which completes the 
hideousness of their figure. They have only two incisors above, and six 
below. 
Those brought from Cape Verd generally have the incisors very com- 
plete—S. africanus, Gm.: in such as are from the Cape of Good Hope— 
S. ethiopicus, Gm.: Buff. Supp. III. xi, they are scarcely visible, some 
vestiges however exist under the gum. This difference may arise from 
age, which may have worn them away in the latter, or it may indicate a 
different species, more especially as the head of those from the Cape of 
Good Hope is somewhat larger and shorter. 
With still more propriety do we separate from the Hogs the 
DicotyLes, Cuv.* 
Or the Pecaries, which have, it is true, grinders and incisors very 
similar to those of the Hog properly so called, but whose canines, directed 
like those of animals in general, do not project from the mouth, they have 
no external toe to their hind foot. There is no tail, and upon the loins is 
a glandular opening from which a fetid humour is excreted. The metatar- 
sal and metacarpal bones of their two great toes are soldered together into 
a sort of cannon bone, like those of the Ruminantia, with which their 
stomach, divided into several sacs, gives them also a remarkable relation. 
It is singular that the aorta of these animals is often found very much 
enlarged, but without there being any fixed situation for the enlargement, 
as though they were subject to a kind of aneurism. 
Only two species are known, both from South America, which 
were ascertained by Azzara: Linneus confounds them under the 
name of Sus tajassu. 
Dic torquatus, Cuv.; Buff. X. iii. and iv. (The coloured Pecari, 
or Patira.) Hair annulated with grey and brown; a whitish collar, 
stretching obliquely from the angle of the lower jaw over the shoul- 
der; half the size of the Wild Boar. 
Dic. labiatus, Cuv.; the Tagnicati, Taitetoc, Tajassou, &c.; 
larger, brown, and with white lips. 
Here may be placed a genus now unknown in the living creation, 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 canines almost like the in- 
cisors, and not projecting beyond them, and seven molars throughout, 
form a continuous series without any intervening space, a diposition of 
the teeth seen in Man only. ‘The four posterior molars of each side are 
similar to those of the Rhinoceros, the Daman, and the Paleotherium; 
that is, they are square above, and form double or triple crescents below. 
Their feet, terminated by two great toes, as in the Ruminantia, differ in 
this—the bones of the metatarsus and metacarpus always remain separate, 
* Dicotyle, double navel, from the opening on the back.
