from the middle of the series backwards. The extremities of all from 
the scapula posteriorly are turned forwards. The metapophyses are con- 
spicuously elevated above the diapophysis on the eleventh dorsal, and on 
the eighteenth, their elevation is about .4 that of the neural spine. The 
diapophysis is extended beyond the tubercular articulation, on the 18th 
dorsal; the extension and expansion increases rapidly on the lumbars. 
On the fourth they are as wide at the base as .66 the length of the cen- 
trum and maintain their width, being directed anteriorly. On the sixth 
and seventh they are still wider and longer, and very thin. They present 
a projecting transverse surface backwards one-fourth the length from the 
base for articulation with the seventh lumbar and first sacral respectively. 
The centra of the lumbars are depressed and slightly opisthoccelian, ex- 
cept the last, which is flat. They are contracted and keeled below. 
The sacrum is long and narrow, and thoroughly codéssified in the speci- 
men. The diapophysis of the first and part of that of the second gives 
attachment, to the ilium. The intervertebral foramina are rather small.

The ribs are long and slender, the first but little expanded distally and 
united with the manubrium sterni a little behind its middle. They num-

pair of shorter ones not yet exposed in the matrix.
