Vertebre. The atlas is deeply incised anteriorly above. It is rather 
short and its transverse processes are flat, thin, about as long as broad 
-and with regular convex distal margin. The arterial foramen issues 
some distance above and within the notch which marks the anterior base 
of the transverse process. It enters at the notch at the posterior base. 
‘The neural arch is quite convex and its anterior margin is obtusely 
rounded. The axis is near the same length and bears a prominent and 
elongate laminate neural spine. Its diapar apophysis is narrow and over- 
laps the parapophysis behind it three-quarters of an inch; it is pierced 
for the cervical artery. The centva of the third and fourth cervicals are 
about equal in length to that of the axis, but the remaining ones shorten 
successively to the seventh which maintains a length somewhat greater 
than its width. The parapophyses of these, except the seventh, are flat- 
tened and have considerable antero-posterior extent, their extremities 
overlapping. A short and rather narrow and stout diapophysis is present 
on the sixth cervical; on the seventh it is larger, especially expanded 
antero-posteriorly at the base, and truncate. There is no parapophysis. 
The fourth, fifth, sixth and seventh have eeoren opisthoccelian centra ; 
that of the third is injured.

The measurements indicate that the neural spines of the sixth and 
seventh are quite elevated, the latter nearly equal to that of the first 
dorsal. 
The spines of the dorsal vertebre are elevated in the front of the series 
rising some distance above the scapule. They shorten and widen rapidly
