In a paper published in this MagazineinMarch, 1895, Dr. J. W.Gregory, incidentally discussing the exact age of the base of the Gault Clay, wrote:“Hoplites interruptus seems restrictedin[Eastern] England to the Folkestone area and the Eed Chalk.” Although some of his conclusions on that point were modified later, the general statement quoted above, with the qualification indicated by the bracketed word ‘Eastern,’ does not seem to have been challenged. Having myself found H. interrnplus at the base of the Gault at several places in Eastern England, I have been led to look up previous records, with the result that I am convinced that the zone of H. interruptus is represented in the lowest beds of the Gault Clay over a large part of that area.
