A NEW GENUS OF CARNIVORA. 31 
which adds considerably to its breadth, and at once distinguishes it from all the other 
teeth. Next in succession follows the carnassier, which is as long as the second and 
third false molars together. In its general form it resembles the third false molar, con- 
sisting of a large trenchant lobe in the centre, with a smaller one on each side, and a 
blunt tuberculous lobe of considerable dimensions on its inner surface. The lateral 
lobes, however, are here much more developed than those of the false molars ; the pos- 
terior one, in particular, occupies nearly half the entire length of the tooth, and from 
its blunt, flattened form, appears to belong more properly to the tuberculous than to 
the carnivorous part of the dentition; and the internal lobe, which exhibits the same 
general characters, is likewise very large, and runs for a considerable way into the 
palate. A section of the whole tooth would form an obtuse-angled triangle, of which 
the anterior lobe would occupy the obtuse angle, and the interior and posterior lobes, 
the two acute angles respectively. The first tuberculous tooth is nearly half the length 
of the carnassier ; but its breadth, or dimensions measuring from the outer surface of the 
jaw inwards, is nearly three times that length: it is perfectly flat on the crown, from 
the effects of long use, but appears to have originally consisted of two distinct tubercles, 
one on the outer, the other on the inner surface, separated from one another by a deep 
depression. The second tuberculous tooth is, as to form, in all respects similar to the 
first, but is little more than half its size. 
In the under jaw the lateral incisors are separated from the canines by a vacant space, 
which receives the upper canine in the reciprocal position of the jaws. The three false 
molars are of the normal form of these teeth in general, resembling the second false 
molar of the upper jaw, but rather larger and more developed, and differing from one 
another in having the lateral lobes successively more distinctly separated from the 
central, scarcely apparent in the first, but large and well-developed in the third. This 
latter tooth wants the interior tuberculous’ lobe of its corresponding analogue above, 
because the narrowness of the under jaw does not permit any development in that di- 
rection ; there seems to be, nevertheless, a faint indication of it on the inner side of 
the posterior lateral lobe, almost in contact with the carnassier. The carnassier, also, 
owing to the same cause, is of a form essentially different from that of the upper jaw. 
It is a long and tolerably thick tooth, with a deep transverse depression in the middle, 
and a small furrow on the interior of the first half. This first part appears to have 
originally consisted of three small but distinct tubercles, one on the outside and two 
within, separated by the small furrow already mentioned. The heel of the tooth con- 
sists of a single large, flat tubercle, which, in the reciprocal position of the jaws, is op- 
posed to the first superior tuberculous tooth: there is no interior tubercle, as in the 
upper carnassier, owing to the restraint imposed upon the development of the lower 
teeth in this direction by the comparative narrowness of the under jaw. The single 
tuberculous tooth is likewise influenced by the same cause. Its greatest dimensions 
are in a longitudinal direction, and it appears equally to have consisted originally of
