neural spine (n) and a hypapophysis (h) developed much as in the 

 preceding vertebra. Both the pre- and postzygapophyses (ptz) 

 project shghtly less than in the tenth vertebra, and an antero- 

 posterior external (interzygapophysial) ridge (iz) connects them — a 

 trace of which is also to be seen in the tenth vertebra. The neural 

 arch is the shortest, antero-posteriorly, since that of the atlas.
