spinous processes of the vertebrae ; the six anterior vetebra, with 
large ribs attached to them, and three ribs at the end of the stone, 
the vertebrae belonging to which are broken off. The five vertebra 
next to those which are connected with the ribs, he remarks, have 
large transverse processes, whilst those of the next four are small. 
The ilia are situated after these four ; but he is of opinion that they 
have been displaced, and that they should have been found behind the 
five vertebrae with large transverse processes, which he considers as 
vertebrae of the loins. The impressions of the ossa ilia were supposed 
by Stukeley to have been of the thigh-bones ; and two large and short 
impressions near them, which M. Cuvier is unable to refer to any 
particular bones, he considered as the heads of the tibia and fibula. 
No marks of the head existing in this fossil, and the vertebra not 
having been figured with precision, no conjectures can be offered with 
respect to the species. 
Captain William Chapman, in the fiftieth volume of the Philosophical 
Transactions, p. 688, gives an account of the finding, on the sea- 
shore, about half a mile from Whitby, part of the bones of an animal 
appearing to have been an alligator. They were found in a kind of 
black slate, which had been covered five or six feet with water every 
full sea, and were about nine or ten yards from the cliff, which is 
nearly perpendicular, and about sixty yards high, and is continually 
wearing away by the washing of the sea against it. The place where 
these bones lay was frequently covered with sea-sand to the depth of 
two feet. 
Mr. Woolers, p. 786, of the same volume, gives a further account 
of the foregoing fossil skeleton. He says : “ In this same rock, am- 
monite, or snake-stones, as they are called, are found. The animal, 
when living, must have been twelve or fourteen feet long. It lay six 
yards from the foot of the cliff, which is sixty yards in perpendicular 
height, and must have been covered by it, probably, not much more 
than a century ago. The cliff there is composed of various strata,
