Tabulated List of Mollusca observed in the Gravels and 

 Underlying Beds. 



Note. — The fossils of the gravel beds A to D having been 

 already investigated by *Hull, "{"Grainger, and others, no ex- 

 haustive examination of these zones was considered necessary, but 

 the lists given below indicate the character of their fauna. More 

 attention was given to beds G, H, and J, as these are not easily 

 accessible, and as their fossils have not previously been catalogued. 

 Beds E and F being subordinate zones, were not separately ex- 

 amined.
