column may be supposed to be the remains of 
two ; then follows one that is compressed, but its 
outline is defined ; the succeeding vertebra is en- 
tire ; it has two tubercles for the attachment of sup- 
plementary transverse processes ; the form of the 
latter unfortunatelv cannot be discovered : the 
transverse ])i*ocesses are short and very strong : this 
bone is 1 *7 inch long and 2 inches wide. The seventh 
cervical is much crushed ; it has traces of the left la- 
teral apophysis. The first dorsal (/>*, Pl.\\) is entire; 
it is 2 inches long, and 2*2 inches wide at the ex- 
tremities ; it is depressed laterally, and the anterior 
part of the body rounded ; the tid)ercle for the at- 
tachment of the rib is well marked ; and the trans- 
verse process short and strong : its rib is near it, 
and shows the deep bifurcation of the head, as in 
the crocodile. The 2d, 3d, 4th, and 5th dorsal 
succeed, and differ but little from each other ; 
except that the 3d is more keeled ; the 5th 
(c, PL V.), which is 2 j inches long, has its left rib 
near it ; and the latter, unlike the four other ribs, 
has no strongly marked bifurcation, but its process 
sinks into a mere tubercle, as in the corresponding 
rib of the crocodile ; and it is this character which, 
in the absence of other evidence, has been taken 
to determine the respective situations in the 
column to which the vertebra^ belonged. The 
2d, 3d, 4th, 5th, and 6th ribs are seen on the left 
side of the vertebra^ ; on the right, the 1st, 2d, 
and 4th onlv remain ; the face of the 6th dorsal 
vertebra is shown beneath the sternal margin of the 
left coracoid, and one of its transverse processes 
appears near the 4th rib (^/, PI. \ .). The 7th,
