THE CORALLIAN ROCKS OF ENGLAND. 



367 



With the immense difference between the Florigemma-Rag and the 

 underlying limestones (Coralline oolite) the most casual observer 

 could not fail to be struck; but here there is a well-marked difference 

 in the group we term the Coralline oolite, as may be seen in the 

 very considerable change which is noted between b and c. The 

 great Chei?mitzia-beds, where developed, are usually found to ter- 

 minate about 10 or 12 feet below the Coral Rag, the intermediate 

 belt of limestone being less obviously fossiliferous. It is quite pos- 

 sible that in other quarries (the old Pye pits for instance) b may 

 have been more fossiliferous, and may perhaps contain a partially 

 " Rag fauna." If this be so, it will serve to explain the mixed 

 character of the following list of fossils : — 



Fossils from the Oolites of Malton and the neighbourhood. N.B. All 

 specimens occurring in a Hag matrix only are excluded from this 

 list.
