Upper St. near Grove Ferry, Chislet, Kent. This is 
a very doubtful species. The figure is not unlike that 
of B. bisulcata , or B. spongicula , to either of which it 
has some resemblance. Mr. John Brown who dis¬ 
covered this deposit, states in his paper (see above) 
that it was present with about 35 other organisms. Of 
the 33 shells, some are undefinable, 10 or 12 are 
undoubtedly Coralline Crag, a few Bed Crag to 
recent, and two or three land and freshwater, including 
Corbicula (Cyrenct) fluminialis, Ilydrobia octona ( Odos - 
tomia , Sp., of J.B. list), and Valvata piscinalis, the 
remainder were undoubtedly lower Eocene, from the 
Thanec sands to the London clay. As seen some 
time afterwards by Prof. Prestwich, and later by 
others, the shells represented an old interglacial lake 
deposit of postpliocene age, reposing upon the Lower
