review of Red Crag literature places this study in context with work on Crag Geology. Results from recent work on the Icenian Crag differ markedly from those of earlier workers, and this study is an attempt to re-examine the Red Crag in the light of these recent results. The limitations of Harmer's methods are discussed. Quantitative methods for studying Red Crag Mollusca are described, ~d assemblage-types are recognised. Information about the molluscs (Appendix II) is used to subdivide assemblages into ecological groups, which are used for palaeoecological interpretations. The relationship between certain extinct species and extant species is studied. Sedimentary structures and granulometric analyses are important in assisting the palaeoecologic interpretations.
