nis, or Crocodile. There are no traces of sternum, 
or clavicles. 
We have next to direct our attention to the bony 
processes which are distributed on the left of the 
vertebral column, and three of which hold so con- 
spicuous a place near the base of the left omoplate ; 
these are marked h h h in Plate V. Of these bones 
there are no less than ten, more or less perfect, and 
varying in size from 5 to 17 inches in length, and 
from 3 to 7o inches wide at the base ; they differ 
much in form, but they apj)roach to an isosceles 
triangle. They are so accurately rc})resented in 
the drawing, that I shall only particularly notice 
the three large examples which lie near the anterior 
l)art of the fossil (//* h* li*^ Plate V.). The longest 
of these is 17 inches in length, and but 3^ wide, at 
six inches from the base, which is broken, and is 
4 inches thick ; tliis bone differs from the cor- 
responding ones in this respect, and more nearly 
resembles the displaced bone (at ?, Plate V.) that 
has a semicircular Jiollow at its largest extremity, 
as if for articulation with another bone. The 
middle process is 13i inches long, and 4*7 inches 
wide at the base, and is flat, and slightly depressed 
in the centre : the third is also very flat ; it is 1 1 
inches long, and the base imperfect. What the 
nature of these processes may be, it must be ac- 
Plesiosauri of Thomas Hawkins, of Glastonbury, Esq., F.G.S., who, 
with his accustomed generosity, presented it to me, on learning 
that it might assist in the elucidation of my investigations. This 
gentleman has in the press a Memoir on the Ichthyosauri and Plesio- 
sauri, with superb plates, in folio, which will shortly appear before the 
public.
