300 MEMOIRS OF THE CARNEGIE MUSEUM. 
of the ribs are very widely separated, the anterior face looking outward, downward, 
and slightly forward. The posterior articulating face for the head of the rib is 
carried upon a rugose protuberance located back of the opening for the inter- 
vertebral foramen. This face looks backward, outward, and slightly upward. 
In vertical cross-section the centrum of this vertebra as well as of those im- 
mediately preceding it from the eighth backward is subtriangular. 
This is true 
also of the succeeding vertebra and of the first three lumbars; less distinctly true, 
however, of the three posterior lumbar vertebrae, which in cross-section become 
11 
oval.
