Two miles south of Withernsea, and not far from Holmplon,Nevills Drain flows into the sea, and for about 300 or 400 yardsthe cliff is very low, seldom more than 10 feet above high low portion is covered by alluvial deposits in some respectsunlike most of those already described. The section (Fig. 10) was?seen in a projecting point near the northern end of the basin. OLD LACUSTEINE BEDS. 85 Fig. 10.—Allmmm in the OUff north of HoVnvpton (seeif, in a projectingpoint).

Unfortunately no plants are yet known in thelowest bed at Holmpton, and the shells belong to species toowidely distributed to throw any light on the question of relative age of this bed, with arctic plants and the submergedforests, will be discussed after the rest of the sections have beendescribed. Professor Phillips examined the same deposit in 1826,but the section he saw was so different from th
