different parts of Lombardy ; Peru ; the Field of Giants, near Santa- 
Fe, in Terra-firma ; and in the province of Chiquitos, in Paraguay , 
have teeth, which are referable to this genus of animals, been found. 
Besides the teeth found in these different parts, he obtained informa- 
tion respecting several others, of which the places where they had been 
found were unknown : the whole being so numerous, as to show that 
this race of animals had left a considerable quantity of their remains. 
From the general form of these teeth, from bones being found with 
them resembling those of the mastodon of the Ohio, and from their 
being reason for supposing that they were accompanied by tusks, no 
doubt can be entertained of their having belonged to this genus. But 
these teeth possess also other specific characters, which sufficiently 
distinguish them from those of the Ohio. The chief, and the most 
general of these, are, that the cones of their crowns are more or less 
deeply grooved, that they are sometimes terminated by several points ; 
and that they sometimes are accompanied by other smaller cones, placed 
on the sides, or in the intervals of the larger cones. In consequence 
of this formation, as the crowns of these teeth are worn down by mas- 
tication, small circles, and then three-lobed, or club-like figures, 
appear where the points were, but not the lozenge-formed figures 
which these parts assume in the animal of the Ohio. From these club- 
like markings Daubenton, P. Camper, and M. Faujas, have been dis- 
posed to consider these teeth as resembling those of the hippopotamus : 
from which, however, they may be distinguished, independent of their 
greater size, by their having six or ten of the club -like markings ; 
whilst, in the teeth of the hippopotamus, there are never more than four. 
The distinguishing of these smaller teeth from each other, was a task 
of much greater difficulty and labour, but has been in a great measure 
accomplished by the assiduous investigations of M. Cuvier. 
From these researches he has been enabled to distinguish five species 
of this genus, which he thus designates: 1. The mastodon of the Ohio. 
2. The mastodon with narrow teeth, found at Simorre and elsewhere.
