The above measurements tend to confirm Cuvier's observation that the metacarpals 

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



g. The Pelvic Girdle (PI. XII). 

 The pelvis of Hyana is characterised by its shortness, its comparatively large size, 

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

 to the size of the animal than in bears, and is prolonged into an anterior downwardly 

 directed hook.

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

 The intercondylar notch of the 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 llyarna, as in Canis and Felis, is represented only by a vestigial metatarsal.
