234 Reports and Proceedings. 



and which Messrs, Gunn and Harmer found in sinking to the Chalk. 

 This band of clay, which forms the base of the Belaugh bed proper 

 {i.e. of the trough thus excavated), was seen on a subsequent exca- 

 vation, made by the Messrs. Wood and the author, to rest with an 

 irregular line upon the white sands forming the bed (B). 



The only doubt felt by Mr. Wood and himself in connexion with 

 the beds of the Crag series in Norfolk is, whether or not the pebbly 

 sands of Belaugh and Weybourne are identical with the pebbly 

 sands and pebble beds which overlie the Chillesford Clay in the 

 neighbourhood of Norwich, of Loddon, of Halesworth, and of 

 Beccles, or whether they do not form a still later deposit. The 

 identity of the pebbly sands containing Tellina solidula at Belaugh, 

 with the similar sands which form the so-called Crag of Weybourne, 

 is sufiScientiy clear, not only on paleeontological, but also on physical 

 evidence, as they may be traced from Belaugh up the valley of the 

 Bure, some distance above Aylsham, and though they disappear 

 under the contorted drift (the upper part of that valley not cutting 

 down sufficiently to reach them), they re-appear beneath the Till all 

 along the base of the Cromer coast-section. This series of pebble 

 beds, however, contains a number of quartz and quartzite pebbles, 

 which do not seem to be present, at least in any quantity, in the 

 beds which rest on the Chillesford Clay further south ; moreover, the 

 fossiliferous pebble-bed at Ditchingham, near Bungay, which, by its 

 position, seems to belong to the latter beds, has not yet yielded the 

 characteristic shell, Tellina solidula : so that for the present they do 

 not express any opinion on the identity of the pebble-beds in these 

 two areas. He mentioned, however, that like the Belaugh bed 

 between Wroxham Bridge and Horstead, the pebble-beds around 

 Halesworth have in many parts destroyed the Chillesford Clay lying 

 up against it, and resting on the Crag sands beneath. Where this 

 is the case the pebble-beds are usually of great thickness (thirty feet 

 and more), and beached up in the continuous slope of oblique 

 bedding, that results from material being thrown subaerially into 

 the angle of rejoose. 



Since writing the above, several more sections have been met 

 with, in which the Tellina solidula shell-bed occurs. One pointed 

 out by Mr. Gunn, between Belaugh and Coltishall, one at Wroxham, 

 and another at Eackheath. There is, probably, an exposure of it 

 at Crostwick, though the author had not been able to find it, as 

 there is in the Museum a specimen of this shell said to have been 

 found at that place. 



After some remarks from Mr. John E. Taylor, the Honorary 

 Secretary, on the geographical range of Astarte and Tellina ; and 

 from Mr. Bayfield on the Iron-pan of Norfolk ; the President said, 

 the most important feature of Mr. Harmer's paper was that it con- 

 troverted a statement made by Sir Charles Lyell, in his "Antiquity 

 of Man," in which work, at p. 213, he represented the Norwich Crag 

 extending and rising above the Chalk in the direction of Wey- 

 bourne, whereas Mr. Searles Wood and Mr. Harmer had proved that 

 this is quite erroneous, that if ever the Norwich Crag existed
