When we were gathering material and data for that portion of the paper on Kent and Sussex dealing with the Dover section we made careful search for Uintacrinus both on the top of the cliff, north of St. Margaret's Bay, and on the high ground immediately to the westward of the cliff. We failed to find it in either situation, and there were no quarries close to the coast. A thick tabular band of flint is seen at the top of the cliff at the north side of St. Margaret's Bay, and this we believe to be the same table of flint which we have called in Thanet the “Whitaker 3-inch tabular band.” If our inference be correct, we are here within 21 feet of the “Barrois sponge-bed,” which forms the basement-bed of the Uintacrinus-band in Thanet.
