VERTEBRAL COLUMN 



127 



foramen is circular and not so close to the anterior border of the arch as in 

 the horse. The posterior notches are not so deep. The transverse processes are 

 stouter, but the foramen transversarium is small and sometimes absent. 



The thoracic vertebrae/ thirteen in number, are larger than those of the horse.
