Without that combination of characters j. 



j. Masseteric crest on malar remote from its inferior 

 edge ; narrowest point of preorbital constriction 

 nearly over the centre of the orbit ; postorbital 

 processes long, often confluent, occipital area 

 narrow, its width across the mastoids less than 

 the width of the cranium, its sides hardly emar-

 bulla behind the stylomastoid smaller than that 



in front of it , Prionailurus.

 of it ; mandible with first premolar much lower 

 than carnassial, condyle high above angular and
