THE POST-PLIOCENE NON-MARINE MOLLUSCA OF ESSEX. 89
column is a list of the British Non-marine Molluscan Fauna (the
names of the extinct forms being in ordinary type); in the second
column their presence in Essex is noted ; whilst in the subsequent
columns are placed the various records under the several localities.
It has been considered advisable to include a full Bibliography
for the convenience of those students who in the future may
wish to work at this subject.
