just below the external astragaline facet. The external border at the cuboid 

 extremity of the calcaneum is even more prominent and recurved than in 

 the existing cats, and the groove for the internal calcaneocuboid ligament 

 is profound. The groove of the cuboid for the tendon of the peroneiis 

 longiis muscle is deep, and commences at the anterior face of the bone, that 

 is, anterior to its position in Uncia concolor and pardus and Cyncelurus juhatus, 

 but its bounding ridge is not carried so far distally as in the panther. The 

 small calcaneal face of the navicular is distinct from the astragaline surface. 

 The character of the internal (free) surface of the head of the second (first) 

 metatarsal shows that there was no hallux (first metatarsal).

Although I do not possess a mandible of this species, I am satisfied 

 that it is more nearly allied to Dinictis and the present genus than to Nim- 

 ravus. It differs from the species of that genus and Archcelnriis in the fol- 

 lowing points : (1) the truncate triangular posttympanic proxiess ; (2) the 

 transverse frontomaxillary suture; (3) the preorbital impressed depression; 

 (4) the superior position of the postparietal foramen.
