other, restrain the motion of the neck. The articular apo- 

 physes, although disposed in a position oblique to the 

 horizon, are parallel with the axis of the spine : the spinous 

 apophyses are high, narrow, and slightly inclined backwards; 

 and beneath is a small spinous process bent a little forwards. 



The first of the dorsal vertebrae has its spinous apophysis 

 inclined as in those of the cervical ; the inferior spinous 

 apophyses are continued only in the five or six first. The 

 four first have only one costal facette on the body, and one 

 on their transverse apophyses ; the six following have two 

 on their transverse apophyses ; and the two last have none. 



The lumbar vertebrae differ from the dorsals in not 

 having any of these facettes ; and the spinous apophyses, as 

 in the dorsal, are straight, wide, and square. 



The two sacral vertebrae are distinguished by their 

 strong, prismatic, transverse apophyses, for the support of 

 the iliac bones. 



The vertebrae of the tail resemble those of the loins, 

 except in their bodies becoming more and more thin and 

 compressed; their transverse apophyses diminish to the 

 fifteenth or sixteenth, and then cease ; their spinous apo- 

 physes become narrower and longer to the twenty-second 

 or twenty- third, and then again diminish, and in the latter 

 ones disappear entirely. Each vertebra from the second 

 has beneath, at its posterior edge, two facettes to carry a 

 branched chevron-formed bone, like an inferior spinous 

 apophysis. 



The ribs are twelve on each side, not reckoning the ap- 

 pendices of the cervical vertebrae. The two first and the last 

 are not joined by a cartilage to the sternum. Under the 

 belly are five pair of cartilages without ribs, which are at- 

 tached to the aponeurosis of the muscles, the two last being 

 fixed to the sides of the pubis. 



The scapula is very small for the size of the animal. Its 

 flat part forms a narrow isosceles triangle, and has no spine :
