slightly convex facet {t.f.) for the tubercle of the rib. The posterior capitular facets, 

 as in the vertebrae in front, are deeply concave and sharply defined. The metapophysial 

 process (m.) above referred to is large, and in the following two (9 and 10) vertebrae 

 forms a prominent forwardly-proj acting point which overhangs the anterior zygapo- 

 physes {a.z.). The eleventh thoralcic is very similar, but the transverse process merely

 almost directly backwards, while the anterior is more distinct, and forms a shallow 

 concavity below and in front of the transverse process.
