Tlie separate bones which appear to have be- 
longed to the reptiles, the character of wliose 
teeth were previously determined, having, however 
imperfectly, been referred to their several genera, 
I now proceed to describe the large specimen 
before us, which exhibits a considerable portion of 
the skeleton of a saurian animal ; and I shall en- 
deavour, by a careful investigation of its osteologi- 
cal structure, to determine what relation it bears 
to the known recent, and fossil species. 
In the summer of the present year (1832), some 
workmen employed in quarrying the Tilgate grit 
in that part of Sussex where it is used as a road 
material, and who had been instructed to preserve 
whatever objects of interest their labours might 
discover, blasted a large block of the hardest 
variety of the stone to pieces, and perceiving traces 
of bones in some of the fragments, placed them 
aside for my inspection, and informed me of the 
circumstance. Upon repairing to the quarry, the 
considerable number of pieces into which the 
block was broken, the extreme hardness of the 
stone, and the unpromising ajipearance of the frag- 
ments of bone that were visible, seemed to render
