in the year 1844, at Aust ; and four years later Mr. Alexander Thompson 
of Aberdeen found the largest bone and presented it to the museum. 
The late Mr. Stutchbury supposed it to be Labyrinthoid, but this opinion 
did not meet with concurrence from eminent persons who had seen it. The 
author took the three bones to Oxford for the purpose of comparing them 
with various large bones possessed by the University Museum. Professor 
Phillips brought the largest into comparison with a femur of the Megalo- 
saurus, and determined it to belong to an animal of that family ; but 
nevertheless an individual much larger than that the remains of which 
are in the Oxford museum. 
Mr. Sanders then gave a brief description of those remains, noticing the 
large size of the hind limb, of which an outline drawing of the natural 
size showed it to be nearly six feet in length. The sacral vertebrse are 
anchylosed together. 
The humerus is \ very much smaller than the femur, so that the hind 
limbs possessed a large proportion of its muscular power. 
A short account was then given of certain huge bones of a Ceteosaurus 
lately discovered near Oxford. The femur of this Saurian measured six. 
feet in length.
