Pocock described the skull of ''Neofelis'' as recalling in general features that of '' Panthera pardus'', especially in the shortness and wide separation of the frontal and malar postorbital processes, relative proportion of mandibular teeth; but differing in the greater posterior width of the nasals, the thicker, more salient inferior edge of the orbit, and the mandible being greatly elevated anteriorly.
