whether the annular part be divided by suture or 
otherwise ; tlie articular apophyses are horizontal, 
and very strong ; the spinous j)rocess is destroyed. 
The other four vertebrie of this system are very 
small, and must have belonged to a young lizard. 
It must be admitted, that even if the above ar- 
rangement of the vertebra' should prove to be 
correct (which it is very probable it may not), still 
the appropriation of the bones to the various ani- 
mals with whose teeth and other remains they are 
associated, cannot be satisfactory until we shall dis- 
cover these relics in juxtaposition with other j)arts 
of the skeleton. We may, however, be permitted 
to hazard the conjecture, that the vertebra; of the 
first system, which approach in so many respects 
to those of the fossil Crocodiles, may have belonged 
to more than one genus or subgenus : some to the 
Crocodiles, which furnished the conical striated 
teeth ; others to the Megalosaurus ; and some to 
the animal whose osteological organisation will 
hereafter come under our notice. 
Ribs . — Fragments of these bones are very abun- 
dant ; and specimens sometimes occur which show 
the bifurcation of the head, for the articulation 
with the transverse process and body of the ver- 
tebra, wliich is so characteristic of the recent 
Crocodiles : they are but slightly arched. The 
same observation will apply to the ribs as to the 
vertebra?, and, in fact, to the other detached bones, 
namely, that they may have belonged to more than 
one genus of reptiles. 
Bones of the extremities. — I shall only notice 
those fossil bones which approximate so closely to
