990 THE JOHIJf DAT FAUNA. 



first named ; while the lateral tuberosities are more pronounced than in any 

 of the species excepting U. X)ardiis and F. domestica, where they are stronger. 

 In U. concoJor an U. leo they are weak, and in C. juhatus wanting. As iu 

 these cats, they are below the line of the base of the diapophysis. The 

 anapophyses are large on the last two dorsals and the first lumbar; on the 

 second and third lumbar they are small, apparently shorter than in the 

 Felidce above mentioned excepting Cyn. jubatus, where they are smaller still. 

 The posterior borders of the neural spines of the lumbars are nearly straight 

 from their origin behind and above the postzygapophyses, and their sum- 

 mits are not much expanded. There is no trough-like excavation between 

 the postzygapophyses above, as is seen in the panther, and in a less degree 

 in the leopard and lion. The centra are not so much depressed as in the 

 panther, leopard, and cat, or even as the lion, where they are the least 

 depressed. 



The femora are a good deal injured, and the heads and trochanters are 

 gone. It is evident, however, that they were of the same general propor- 

 tions as those of the Nimravus goni])Jiodus^ and not very different from those 

 of the panther. The external linea asper is acute, and the rotular groove 

 high and rather narrow. The fossa between the insertions of the crucial 

 ligaments between the condyles is deeper than in recent cats. The head of 

 the tibia is also injured. (See fig. 6.) The internal posterior surface for the 

 attachment of the cruciform ligament is large. The patella is a little nar- 

 rower and more convex within than that of the panther. The bones of the 

 foot preserved show clearly that, as in the case of the Arcliadurus dehilis, 

 the extremities are relatively smaller than in recent Felidce of similar gen- 

 eral size. While the portions of the skull of the Pogonodon hracliyops indi- 

 cate an animal of rather larger size than the Uncia concolor, the bones of 

 the hind foot are considerably smaller. The calcaneum is about three- 

 fourths as long; the navicular is narrower though nearly as deep antero- 

 posteriorly; the diameters of the cuboid are all less excepting the inferior 

 facet anteroposteriorly ; the first metatarsal is more slender, and its proximal 

 facet is little over half as wide. One character of the calcaneum which I 

 do not find in any of my skeletons of Felidce or Hycenidce, is the presence 

 of a longitudinal fossa for the insertion of the external lateral ligament,
