STRATA OF TILGATE FOREST. 
With the assistance of Mr. Lyell, and aided by 
an interesting collection of Stonesfield fossils, for 
which I am indebted to his liberality, I have been 
able to ascertain that the following organic remains 
occur in both deposits, viz. : — 
The teeth, ribs, and vertebrm of the Megalo- 
saurus. 
Bones and plates of several species of Turtle. 
Teeth of a species of Shark, and of a fish re- 
lated to Lepisosteus. 
Teeth of Crocodiles. 
Scales of fishes. 
Radii of Siluri. 
A plant of the genus Car ex, allied to recent 
species. But the resemblance extends no farther ; 
the Trigonice wadBelemnites of the Stonesfield slate 
do not occur in the Tilgate beds ; and the Palu- 
din<x, Cyclades, &c. of the latter, have not been 
discovered in the former deposit. It is scarcely 
necessary to add, that the strata of Tilgate Forest 
exhibit no traces of oolitic structure.
