and rounded ; the zygapophyses are large, directed more 

 or less antero-posteriorly, and their articular facets are 

 inclined to one another at a considerable angle. 



The overall length of the vertebra over the zyga- 

 pophyses is 4^5 cms., and the maximum breadth across 

 the anterior zygapophyses is 5 cms. 



The zygapophyses unite together forming a table 

 similar to that of Sthcnarosajcrus. It is, however, less 

 flat, much narrowed before the posterior zygapophyses, and 

 shews a slight notch separating the anterior and posterior 

 zygapophyses. 



The spine is about r5 cms. long, and i cm. thick. It 

 is broken off short in all the vertebrae in this region, but 

 was probably never very high.
