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 vertebra, thirteen in number, are larger than those of the horse.
