fers very materially in having remote satural surfaces for the 
| attachment of the neural arches, in being somewhat cordate in 
shape and in showing no surfaces for articulation of the chevrons. 
The ends are concave as in the intercentrum, and the notochordal 
foramen is of the same relative size. The anterior lips of the cup 
are more beveled than the posterior ones. The outer surface is : 
concave longitudinally with an obtuse keel below. The posterior 
sutural surface for the arch is much larger than the anterior. There 
are no longitudinal ridges on the sides of the centrum, as shown 
in the figures of C. crassidiscus Cope (labeled C. heteroclitus by 
| Zittel). The floor of the neural canal is flat.

None of the characters are sufficient to distinguish the species 
from the other described ones, especially C. heteroclitus Cope.
