4345. The last two lumbar vertebrae. 



The metapophyses have disappeared. The diapophyses are much produced by the con- 

 nate pleurapophyses. 



4346. The sacrum. 



It consists of three anchylosed vertebrae : the articular surface for the ilium extends from 

 the first upon the sides of the fore part of the second vertebra. 



4347. The ten anterior caudal vertebrae.
