378 Reports and Procecdings— 
that of the “ Westleton and Mundesley Beds,” which the author 
proposed in 1881. 
The Westleton Beds were carefully described, as seen in coast- 
sections in Hast Anglia, proceeding from south to north, and the 
following classification was adopted :— 
(1. Laminated clays, sand, and shingle with plant-remains 
The Westleton and freshwater shells (the Arctic forest-bed of Reid). 
and Mundesley 2. Sand and quartzose shingle with marine shells (the 
series 4 Leda myalis bed of King and Reid). 
(the Mundesley 3. Carbonaceous clay and sands with flint-gravel and 
section of it). pebbles of clay, drift-wood, land and lacustrine shells 
and seeds (the Upper freshwater bed of Reid). 
4, A greenish clay, sandy and laminated in places, con- 
g Ni yj P 
taining abundant mammalian remains, and drift-wood, 
ee | with stumps of trees standing on its surface (the 
(exclusive ae Nae 4 forest- and elephant-bed of authors; the estuarine 
division, in part, of Reid). 
5. Ferruginous clay, peat, and freshwater remains and 
( gravel (the Lower freshwater bed of Reid). 
The Westleton Beds were found to rest with discordance on 
various underlying beds; in places on the Forest series, elsewhere 
on the Chillesford Clay, whilst occasionally the latter had been 
partly or entirely eroded before the deposition of the Westleton 
Beds. In the north, where the present. series dies out, they come 
in contact with the so-called Weybourn Crag, which the author 
supposed to be the equivalent of the Norwich Crag. A similar 
discordance has been noted between the Westleton Beds and the 
overlying glacial beds, so that the former mark a distinct period, 
characterized by a definite fauna, and by particular physical con- 
ditions. The Westleton Beds being marine, and the Mundesley 
Beds estuarine and freshwater, the author proposed to use the 
double term to indicate the two facies, as has been done in the case 
of other deposits. But these facies were found to be local, and the 
most persistent feature of the beds is the presence of a shingle of 
precisely the same character over a very wide area. By means of 
this the Westleton Beds can be identified far beyond Hast Anglia, 
and where there is no fossil evidence, and they throw considerable 
light on important physiographical changes. 
The author described the composition of the shingle, which, unlike 
the glacial deposits, contained pebbles of southern origin. 
The paper concluded with a list of fossils, excluding those of the 
Forest-bed (the stumps of which, the author considered, were 
frequently in the position of growth). Should the Forest-bed 
eventually prove to be newer than the Chillesford beds, it was 
maintained that the former must be included in the Westleton 
series, and its flora and fauna added to the list, whilst if, on the 
contrary, the Forest-bed should be proved synchronous with the 
Chillesford Beds, it must be relegated to the Crag. 
The second part of the paper will treat of the extension of these 
beds into and beyond the Thames Valley, and on some points con- 
nected with the physical history of the Weald.
