4446. The skeleton of the Spotted Hyaena (Hyaena crocuta}. 



The vertebral formula is: 7 cervical, 15 dorsal, 5 lumbar, 4 sacral, and 19 caudal : the 

 first caudal has become anchylosed to the normal sacrum in this aged individual. Eight pairs 

 of ribs articulate directly -with the sternum, which consists of eight bones : the dried costal car- 

 tilages are preserved. The transverse processes of the atlas are perforated longitudinally and 

 vertically by the vertebral artery before this perforates the neural arch. The strong spine of 

 the axis is bifid posteriorly ; the transverse processes of the seventh cervical are imperforate. 

 The convergence of the dorse-lumbar spines towards that of the thirteenth dorsal is feeble 

 compared with other Carnivora. Anapophyses begin to be developed on the thirteenth dorsal 

 and subside on the penultimate lumbar vertebrae. The humerus is neither pierced above the 

 inner condyle nor between the condyles : it is thicker in proportion to its length than in the 

 Dog, but is more bent and twisted : the same characters mark the radius and ulna, which are 

 still shorter in proportion than in the Dog. The scaphoid and lunar bones are connate ; the 

 pollex is reduced to a rudiment of its metacarpus. The femur is more compressed antero- 

 posteriorly than in the Dog, and the small trochanter is more posterior in position. The
