A left mandibular ramus which lacks all posterior to the last molar, and which 

 retains two molars (pm. 1 and m. 1) and the canine, represents this cat. The pm. 2 

 was probably lost during the life of the animal, as the alveolar region is roughened 

 anterior to the pm. 1. 



The dentition is characterized by the very small size of the posterior lobe of 

 the pm. 1, although the heel is well developed. The anterior basal lobe is small 

 but distinct. There are two mental foramina, one below the position of the lost 

 pm. 2 and a larger one in front of the same tooth. This agrees with the character 

 of our specimen of eyra in the museum of the Academy, while in a more mature 

 specimen than the last, but one mental foramen is present on both sides. The 

 inferior canine has the usual groove in the fossil jaw, and the masseteric fossa 

 extends to the line of the posterior border of the sectorial tooth.

An isolated calcaneum of a cat of the dimensions of the present species differs 

 considerabty from that of eyra. The principal difference is the rounded external 

 border of the cuboid facet. In eyra this facet is obliquely truncate externally.

This species is represented by left maxillary and premaxillary bones, which 

 support the i. 3, c, pm. 1, 2. Besides this specimen there is another which includes
