FELIS SPELtEA.

longuH (fig. 2, /). The cuboidal articulation (fig. 2, h) terminating the bone distally 

 at right angles to the axis forms a nearly circular surface, a portion of the circle being 

 cut off by a chord, which forms the inner posterior boundary of the articulation. If this 

 cord were slightly bent, it then would approximate very closely to the recent leonine form, 

 which is nearly an oval. 



The attachment of the tendo ALchillis is formed by the process rising on the inner 

 edge of the bone at right angles to the rounded terminal surface (fig. 2, y). In this it 

 appears to differ slightly from that of the lion, for in that animal the groove formed by 

 the two surfaces is replaced by a nearly fiat or slightly rounded surface at an angle 

 of about 4 5° to the axis. 



The only differences which we can observe between the corresponding bones of this 

 animal and the tiger are that mentioned above, and the rounded or oval form of the 

 cuboidal articulation in the former, while in the latter it forms a quarter circle. 



Among the large number of calcanea we have examined, we find three or four which 

 do not appear to differ in any respect from those of hon, with the exception of being 

 very slightly larger, the difference of size in general being very great. That figured 

 probably belonged to an aged animal, the outer portion of the bone being roughened 

 by exostosis.
