Clement Reid — Pliocene Beds near Cromer. 



exliibited a worn and frayed-out appearance, and did not end in 

 rootlets, as published descriptions would lead us to exj)ect. It 

 is not sufficient to find stools of trees in any upright j)Osition, as 

 when laden with earth and stones they would naturally sink with 

 the roots downwards. It is possible that hidden in some part of the 

 beach there may be a submerged forest that I have not yet seen, but 

 the masses of drift wood already described are what Norfolk geo- 

 logists speak of as the " Forest-bed." I am informed that Mr. 

 Norton, of Norwich, has communicated a paper to the Norwich 

 Geological Society, expressing his opinion that none of the stools 

 of trees he has observed at Mundesley have grown on the spot. 



From the facts I have been enabled to gather, I have been led to 

 regard the " Forest-bed " as an estuarine equivalent of the upper 

 part of the marine Weybourn Beds, and not as a land surface. 



From the lower marine bed at Eunton I have obtained the 

 following species, most of the land and fresh-water species only 

 occurring: with the bones : 



c. eommon. r. rare. 



Biiccinum undatum, v.r. 

 Selix arbustorum, r.

* In their natural position with the valves united. 



t In their borings about six feet above the present high-water mark near 

 Sherringham. 



I have as yet been unable to obtain any additional species 

 from other sections on the coast ; but I should mention that Prof. 

 Prestwich's list contains Venus fasciata from the lower, and Leda 

 lanceolata from both upper and lower beds at Weybourn. Leda 

 oblongoides, which is not contained in Prof. Prestwich's list, is 

 rather common ; but I cannot find L. lanceolata, although I have 

 repeatedly searched for it.^ 



The mineralogical character and fossils of the beds just described 

 point to an estuary advancing seaward in a northerly direction. The 

 relation of the sea-level to that of the land differed probably about
