FELIS SPELtEA. 



9 



All the specimens that we have seen are from the caves of Bleadon, Sandford Hill, 

 and Hutton, and are in the Taunton Museum. 



This bone may be distinguished from that of the bear by the greater prominence of 

 the eminence of the humeral articulation in the latter animal (figs. 1, 2, 4,/). This 

 articulation is more circular in Eelis than in TJrsus. In the bear the ulnar proximal 

 articulation is less pronounced and more rounded vertically ; the tuberosities below this 

 articulation are far smallei-, and the bone is altogether more angular in section, more 

 slender and flatter ; the distal ulnar articulation is set nearly parallel to the axis of the 

 bone on a small process. In the carpal articulation the strong upward curve on the 

 hiternal edge altogether disappears, and the articulation is much less concave. 



Schmerling, in his ' Oss. foss» de Liege,' gives good rough figures of this bone, both 

 of the large variety (vol. ii, pi. xv, fig. 3) and of the smaller with the ulna (pi. xix, fig. 1).
