FELIS SPELtEA. 7 



shallow grooves between ; while the smaller and more strictly leonine forms present more 

 angular and less defined ridges, and the grooves between appear to be more cut up by 

 small irregular supplementary ridges. 



Fragments of this bone are very numerous in collections of Somerset bones from the 

 caves of Hutton, Bleadon, Sandford Hill, and Wookey Hygena-den, specimens of both 

 varieties having occurred in all. The largest number we know of together is in the 

 Taunton Museum, from the collections of Messrs. Williams and Beard. 



The only bone of the Pleistocene deposits that is likely to be mistaken for this is the 

 same bone of the bear. The latter is, however, much straighter, and never has the broad 

 external groove of the shaft described above. But the most marked distinction is in the 

 proximal radial articulation, which in F. spelcea, as in all the Eeles, invariably forms an 

 acute angle with the axis of the bone, while in the bears it is at right angles. The form of 

 the olecranon is also somewhat different, but its irregular form can be more easily recog- 

 nised by a comparison of the plates of the bones than from the most elaborate description. 



There is a figure of this bone belonging to the smaller variety in Schmerling's ' Oss. foss. 

 de Liege,' vol. 2, pi. xix, fig. 1, and a very characteristic one figured by Marcel de Serres, 

 &c. ' Oss. foss. de Lunel-Viel.,' pi. viii, fig. 3.
