Miss M. E. J. Chandler — The Hordle Marine Bed. 229 



broken shell-fragments and the admixture of freshwater and 

 brackish water shells suggests that in exceptional storms large tidal 

 waves rushed further westward up the estuary than usual, or broke 

 across some barrier, by which they were ordinarily excluded. Each 

 such incursion might be marked by the formation of a " marine " 

 pocket in the midst of the white sands, which were being deposited 

 at this time under more tranquil, normal conditions. Further Avest, 

 beyond the immediate infliience of such incursions, calcareous 

 marls with a thriving freshwater molluscan fauna were being 

 deposited approximately contemporaneously. 



The whole matter was, indeed, rightly estimated by Judd when 

 he stated that " the importance of this so-called ' marine-band ' . . . 

 has been much overrated. It is not a distinct formation . . . but only 

 one of numerous local intercalations of brackish-water bands, 

 among the Oligocene strata of this area." 



My thanks are due to Professor Marr, F.R.S., for allowing me 

 access to the Marine bed material in the Sedgwick Museum.
