fossil skeleton of the Proteo-Saurus. 
made out, but these may be said to be the only ones with 
which we are now not acquainted. 
This magnificent specimen is represented of its full size, 
in the annexed drawing, which has been made with so much 
ability by Mr. Clift, as to require no verbal explanation. 
Since this Paper was laid before the Society, the author has 
received from Sir Joseph Banks a specimen containing five 
fossil vertebrae of the Proteo-Saurus, each of them two inches 
in diameter, and one inch in thickness, found in the blue 
lias at Weston, near Bath, sent to him by the Rev. Daniel 
Lysons. This fact is important, as it proves that the fossil 
bones met with in the blue lias in that neighbourhood, which 
have always been considered to be those of the Crocodile, 
belong to this animal.
