proximation to Paradorurus ; the only important difference consists 
in the smaller antero-posterior extent of the coronoid process. 
The teeth in Prionodon differ much from those of Paradozxurus ; 
indeed, were the dentition alone to be considered, these two genera 
would be placed at opposite extremes of the Viverrine group, the 
last-mentioned genus evincing the nearest approach to an omnivo- 
rous diet, whilst the Prionodon possesses teeth the most unfitted for 
mastication. 
The incisors are arranged closely together, and in a straight line ; 
the incisor on each side of both jaws, nearest the canines, is rather 
larger than the others, which are slightly notched at the extremity. 
The canines are rather long, very slender, and moderately curved. 
The false molars, which are are much compressed, high, and 
4.4 
sharply pointed. The foremost false molar, both of upper and lower 
jaws, is small, and has a small tubercle on the hinder part of the 
principal cusp. The second and third false molars of the upper jaw 
have each two small notches, and a corresponding number of small 
tubercles on the posterior margiv. and at the base of the principal 
cusp ; and there is an indistinct tubercle in front, near the base : the 
second, third, and fourth false molars of the lower jaw have also the 
double notch behind, but differ in having a distinct, though small, 
anterior cusp. The first and second false molars of both jaws’are 
separated from the other teeth and from each other by interspaces, 
of which the broadest is that which separates the second and third 
of these teeth in the upper jaw, the space here being nearly a line 
in width. The carnassier of the upper jaw very nearly resembles 
that of the Cat, but the central cusp is higher, and the inner tubercle 
is proportionally smaller. ‘The carnassier of the lower jaw may be 
best described by comparing it with the corresponding tooth in the 
Genet, from which it differs only in having the cutting edges rather 
more produced, in being more compressed; the inner tubercle is 
more pointed, and the heel proportionately smaller. As regards 
the true molars, the present animal differs from other Viverride in 
possessing but one of these teeth on each side of the upper jaw; its 
1-1 . : : 
true molars are therefore Toy’ and this certainly does not arise from 
immaturity in the animal. The form of this tooth closely resembles 
that of the foremost of the two upper true molars in Genetta, but is 
proportionately rather smaller and the tubercles are somewhat more 
developed. The true molar of the lower jaw is a mere rudimentary 
tooth, and differs from that of Genetta and other Viverride, not only 
in its small size, but in being of a compressed form: its cutting edge 
is divided by notches into three parts. 
In the possession of but one true molar in the upper jaw, Priono- 
don would appear to approach the Felide; but the structure of this 
tooth, it must be observed, is essentially the same as in the Viver- 
ride, and it is combined with a small true molar in the lower jaw, 
which is never found in the Cats. 
On the whole, Prionodon approaches most nearly to the Genets as
