Dentition. The normal adult dental formula of Hycena, in which, 

 for palaeontological purposes, at all events, Crocuta is best included, 

 is I. |, C. p. Pm. |, M. |. In certain fossil forms, however, pm. 1 is, 

 either occasionally or normally, absent, while in others pm. i is 

 normally developed ; and in others again m . 2 may be present. The 

 range of variation in the dentition may therefore be expressed 

 by the following formula : viz. I. f , C. \, Pm. <|=g, M. (1 _J_ 2) . It 



(1 __ 2) . 



is, however, not improbable that the upper true molar may be 

 entirely wanting in some instances.

Canis crocuta, Erxleben 6 . 



In this species m . i has a small talon and no inner cusp ; 

 m. 1 is always minute, and may possibly bejabsent'in some instances ; 

 it has either one or two fangs. In one skull 7 there is on one side 

 the alveolus of a minute m . 2. The hinder lobe of pm. 4 is larger 

 than the middle ; and there is no distinct anterior talon to pm. 3, 

 which is set parallel to the molar alveoli.
