98 ALBIAN FOSSILS DISCOVERED AT OKEFORD FITZPAINE. 



TABLE EXHIBITING THE GEOGRAPHICAL DISTRIBUTION, in sonic of 

 the chief Albian areas of England, of the twenty-four 

 named species of Mollusca obtained from the Hoplites inter- 

 ruptus Zone at Okeford Fitzpaine. 



For purposes of correlation this table is interesting as showing 

 that 19 of the species occur at Folkestone, 12 at Black Ven near 

 Lyme Regis, 12 in the Cambridge " Greensand " deposits, 11 in 

 the Blackdown beds of Somersetshire, and 3 in the Red Rock of 

 Hunstanton.* Lithologically the Gault at Okeford Fitzpaine more 

 closely resembles the Black Ven beds than the bluer and more 

 clayey deposits of Folkestone. 



* The occurrence of Hoplites intcmiptus in the Red Chalk of Hnn- 

 stanton is given on the authority of Messrs. Jukes-Browne and W. Hill.
