CREODONTA. 323 



articular faces of a median dorsal are a little wider than deep, and the 

 width is not equal to the length of the centrum. The outlines of the latter 

 are gently concave, and it is not keeled below or on the sides. Surface 

 smooth. The femur is preserved, lacking the distal extremity inclusive of 

 the rotular groove. It is about as long as that of the jaguar, and is moder- 

 ately slender. The head extends rather further proximally than the great 

 trochanter, and is defined by a distinct neck. The fossa ligamenti teris is 

 a wide posterior emargination of its edge. The great trochanter is recurved 

 on its external border posteriorly, but the trochanteric fossa is open proxi- 

 mally and fades out anteriorly and below. The little trochanter is large 

 and has a long base. The third trochanter is a thickened angular concavity 

 of the external border opposite a point a short distance below the little 

 trochanter. The feet were evidently large; the proximal extremity of the 

 fourth metatarsal is about equal in dimensions to that of a lion.
