 ably slenderer teeth.

FELIS near ATROX Leidy 



Figure 29 



Several feline foot bones in the collection appear to be much too 

 large and robust to belong with the upper tooth and jaw portion re- 

 ferred to Felis inexpectata and may represent the large North American 

 Pleistocene cat Felis atrox Leidy (1853). Included in this foot material 

 are a scapholunar and second metacarpal (fig. 296) representing the 

 manus and an astragalus, calcaneum (fig. 29a), and the third (fig. 29c) 

 and fifth (fig. 29c^) metatarsals from the pes. There is no evidence to 

 show that these bones are from the same individual. 



These elements are much too big to belong to a large jaguar or 

 even an unusually large puma. The proportions are comparable to 

 those in the foot of a specimen of Felis tigris or F. leo. The scapho- 

 lunar is distinctly larger than in any of the tiger or Hon carpi examined 

 and shows a relatively deeper groove for its articulation with the 

 magnum. However, the second metacarpal, though equally as long 

 as in these large Asiatic and African cats, is somewhat slenderer, and 

 the proximal end does not have so large an articular facet for the 

 trapezoid.
