The above meastirements tend to confirm Cuvier's observation that the metacnrpnls 

 of the cave hyaena are relatively shorter than those of the living spotted hvfciia. 



G. The Pelvic Girdle (PL XII). 

 The pelvis of Hi/ana is characterised by its shortness, its comparatively large size, 

 and its obliquity with regard to the sacrum. The ilium is decidedly laiger in proportion 

 to the size of the animal than in bears, and is j)rolonged into an anterior downwardly 

 directed hook.

H. The Posterior Limb (Pis. XIII, XIV). 

 The intercondylar notch of tlie femur is less deep than in Canis. The cnemial crest 

 of the tibia gradually dies away instead of being strongly truncated as in Canis. The 

 hallux in Hyaena, as in Ca7iis and Fdis, is represented only by a vestigial metatarsal.
