The maxillary bone of the second specimen contains all the molars, the 

 third and fourth somewhat mutilated. The second is plainly two-rooted, 

 and is half way between the canine and the third, which teeth are separated 

 by a space equal to the length of the base of the anterior lobe of the latter. 

 This tooth has no anterior basal lobe, but the posterior heel is rather elevated, 

 though short. The sectorial is large ; its cusps are lost. The tubercular 

 molar is small, and is esjjecially remarkable for its small transverse extent, 

 which is about equal to that of the Nimravus gomphodus, and less than half 

 that of the Pogonodon platycopis. It has nevertheless three roots, the median 

 of which is posterior. The external end of the crown is visible from the 

 side, behind the sectorial. Parts of both canines are preserved. A fragment 

 from the front of the crown shows that the anterior cuttinof ed^e becomes 

 lateral, and is denticulate. The anterior face has a shallow groove next the 

 cutting edge. Enamel slightly roughened. 



The foramen infraorhitale is higher than wide in this species, and its ex- 

 ternal border is above the anterior border of the antei'ior root of the sectorial, 

 the supenor border of tlie molar being horizontal. The masseteric surface 

 of the molar is vertical, not horizontal. 



The remaining parts of this specimen are two dorsal and three lumbar 

 vertebrae, portions of both femora ; a patella ; proximal end of tibia ; both 

 calcanea ; the cuboid and navicular bones, and first metatarsal. The verte- 

 brae are well preserved ; see Plate LXXIV, figs. H-5. To compare with 

 these I have at hand the corresponding parts of Uncia leo, U. concolor and 

 U. pardus^ Cynonluriis jubatus and Fells domestica. The dorsal vertebrae are 

 shorter and a little wider than those of U. concolor and U. pardus; also flat- 

 ter below, and more distinctly medially keeled. Their proportions are 

 more asjn the lion, where they are, however, regularly convex and not 

 keeled. The anterior three lumbars are, on the other hand, of the pro- 

 portions seen in U. concolor ^ U. pardus, and G. juhatus ; that is, relatively 

 longfer than in the lion and shorter than in the common cat. Their 

 centra are medially keeled below, but not so strongly as in the three species
