Daptophilus squalidens. Gen. et sp. nov. 

 General character of dentition as in MacJiaerodus, but the mandibular 

 teeth are L. 1 ; Pm. 3 ; M. 1 ; a premolar tooth being added. Second 

 premolar three lobed ; carnassial tooth with short cutting heel ; tuber- 

 cular none. Superior canine much compressed, denticulate, not grooved. 

 Char, specif. Third premolar with the anterior basal tubercle very- 

 large, equalling, relatively, the corresponding lobe of the carnassial 

 (much smaller in Dinictis felina) . Second premolar two-rooted. Enamel 

 smooth. Ramus decurved at symphysis. Superior canine in shape like 

 a tooth of a shark of the genus Oxyrhina ; flat within, slightly convex 

 without ; the front cutting edge turned inwards at the basis.

Tomarctus brevirostris. Gen. et sp. nov. 



Established on a mandibular ramus supporting a perfect carnassial 

 tooth and fangs of the following dentition : C. 1 ; M. 4 ; the last incom- 

 plete, hence the number of posterior teeth unknown. The ramus is 

 much narrowed in front. The carnassial has an inner tubercle behind 

 the median lobe, and a large posterior heel supporting both inner and 

 outer tubercles. The succeeding tooth was wide. 



Char specif. First premolar one, second two-rooted. Anterior half 

 of the carnassial with the usual sectorial structure, the anterior lobe the 

 smaller. The inner tubercle about the same height. The heel constitutes 

 one-third the length of the tooth, and its lateral tubercles are angular, 

 the posterior low. Enamel slightly rugose.
