Diagnosis

Reference	Diagnosis
E. D. Cope 1873 (Daptophilus squalidens)	Third premolar with the anterior basal tubercle very large, equalling, relatively, the corresponding lobe of the carnassial (much smaller in Dinictisfel'i-nct). Second premolar two-rooted. Enamel smooth. Ramus decnrved at symphysis. Superior canine in shape like a tooth of a shark of the genus O:cyrhinci; flat within, slightly convex without; th~ front cutting edge turned inwards at the basis.
P. Z. Barrett 2016	Same as genus.
