Clement Reicl — Pliocene Beds near Cromer. 
exhibited a worn and frayed-out appearance, and did not end in 
rootlets, as publisked descriptions would lead us to expect. It 
is not sufficient to find stools of trees in any upright position, as 
when laden with earth and stones they would naturall y sink with 
the roots downwards. It is possible tbat hidden in some part of the 
beach tbere may be a submerged forest that I have not yet seen, but 
the masses of drift wood already described are what Norfolk geo- 
logists spealc 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 Runton I have obtained the 
following species, most of the land and fresh-water species only 
occurring with the bones : 
c. common, r. rare. v.c. 
Buceinum undatum, v.r. 
Helix arbustorum, r. 
hispida, v.r. 
Zimncea palustris, v.r. 
Litlorina littorea, v.c. 
rudis, r. 
Melampus pyramidalis, v.r. 
Natica catena, c. 
clausa, v.r. 
helicoides, r. 
Faludina vivipara, 1. 
? ylacialis, 2. 
media, 2. 
Flanorbis corneus, 1. 
Pleurotoma turricula, r. 
Purpura lapillus, v.c. 
Scalaria Grccnlandica, c. 
Succinea putris, 1. 
Trophon antiquus, v.r. 
(reversed var.), r. 
Turritella terebra, v.r. 
very common, v.r. very rare. 
Astarte borealis, v.c. 
compressa, c. 
sulcata, r. 
Cardium edule, v.c. 
Grcenlandicum, v.r. 
Corbula striata, r. 
Cyprina Islandica, v.c. 
Dotiaz vittatus, r. 
Beda oblongoides, e. 
Lucina borealis , v.r. 
Maclra ovalis, r. 
* Mya arenaria, v.c. 
truncata, v.r. 
* Mytilus edulis, c. 
Nuctila Cobboldiie, c. 
t Pholas crispata, c. 
Saxicava arctica, r. 
Tellina Balthica, v.c. 
lata, v.r. 
* obliqua, v.c. 
pratenuis, 1. 
Unio pictorum? 1. 
* 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 otker sections on the coast; but I should mention that Prof. 
Prestwich’s list contains Venus fasciata from the lower, and Ledn 
lanceolata from both upper and lower beds at Weybourn. Leda 
oblongoides , whicli is not contained in Prof. Prestwich’s list, is 
rather common ; but I cannot find L. lanceolata, although I have 
repeatedly searched for it . 1 
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 difiered probably about
