There were two portions of bones of the fore limb in this cave, 

 namely, the shaft and distal -end of a humerus and the proximal 

 end of an ulna. As the bones of the British Museum skeleton are 

 wiied together, it is practically impossible to measure the anconeal 

 fossa of the ulna ; but, so far as could be seen, the Cales Dale 

 fragment agrees in form with the corresponding part of the 

 skeleton in question, though it is somewhat larger. 



An axis vertebra (text-fig. 26 C) from Cales Dale agrees gene- 

 rally with that of the Northern Lynx (B.M. 1230 a), and only 

 differs to an extent which might be expected in the bone of a 

 rather larger and moi-e powerful animal.
