Dentition.—The normal adult dental formula of Hyena, in which, 
for paleontological purposes, at all events, Crocuta is best included, 
is I. 5 C. - Pm. M. i: In certain fossil forms, however, pm. 1 is, 
either occasionally or normally, absent, while in others pm. 1 1s 
normally developed ; and 1 in others again m. 2 may be present. The 
range of variation in the gue may Mage be Pee 
by the following formula :—viz. I. 2 ea = Pu. (2, M. a =>: It 
is, however, not improbable that the ate true molar may be 
entirely wanting in some instances.

In this species m,1 has a small talon and no inner cusp; 
m. 1 is always minute, and may possibly befabsent'in some instances ;

than the middle; and there is no distinct anterior talon to pm. 3, 
which is set parallel to the molar alveoli.
