The cuboid is narrower in proportion to its length than that of the 

 lion. The posterior and anterior surfaces converge outwardly, 

 making the external surface shorter than the internal. The poste- 

 rior surface is convex; the groove for the tendon of the per omens 

 longus and the ligamentary prominence posterior to it extend 

 across the entire inferior surface. The facet for the navicular is 

 long and curved; that for the ecto-cuneiform is semilunar in out- 

 line. The anterior surface is concave to receive the fourth and 

 fifth metatarsals. 



The metatarsals are about one-half the length of those of the 

 lion. Only the fourth, fifth, and half of the second are preserved. 

 The fifth articulates with the cuboid by about half of its posterior end 

 which is sloping and extends but little back of the facet. The tu- 

 berosity projects prominently outward and backward. The fourth 

 overlaps the fifth and in turn is overlapped by the third much as 

 in the recent cats. The shafts are sub-triangular in section and 

 are strongly curved near the distal end. The second is about as 

 strong as the fourth; its proximal end is laterally compressed. 

 The superior surface is symmetrically rounded, instead of sloping 

 outward as in recent forms and its inferior process does not project 

 under the third. The exterior articulating surface and the liga- 

 mentary attachments indicate a fairly well-developed first toe. The 

 proximal series of phlanges are short and stout. The second series 

 are markedly concave above, indicating a perfectly retractile claw.
