THE present section of this chapter will be devoted to the 

 examination of the fossil remains of the other genera of 

 saurians from the Wealden formation of the south-east of 

 England, that are contained in this department of the na- 

 tional Museum. 



The most remarkable of these extinct forms is the Hylceo- 

 saurus, or Wealden Lizard, of which there are three highly 

 interesting specimens, which were formerly in my collection. 



HYL^EOSAURUS OwENii. 1 Wall-case B : in the middle of the 

 lowermost compartment, (ante, p. 139.) In the summer of 

 1832, upon visiting the quarry in Tilgate Forest, now fami- 

 liar to my readers, I perceived traces of bones in some large 

 masses of stone thrown on the road-side ; and on repairing to 

 the quarry, found the workmen had put by other fragments 

 for my inspection ; but the numerous pieces into which the 

 original block of stone was now broken, the excessive hardness 

 and refractory character of the grit, and the unpromising ap- 

 pearance of the few vestiges of bone that were visible, seemed 

 to render it hopeless to obtain anything of interest. I re- 

 solved, however, to collect the scattered fragments, and after 

 much labour, succeeded in cementing them together, and re- 

 ducing the specimen to the state in which it now appears.
