60 RELATIONS TO OTHER BRITISH DEPOSITS. 



of Lower Greensand rock groups as developed further east on the 

 coast of the Weald area in Kent. 



The Godalming section is as follows (Meyer): 



3. Upper series (Folkestone beds, Meyer, = Folkestone 

 beds, Sandgate beds and upper part of Hythe beds, 

 Geo]. Survey). — Sands, carstones, and shelly lime- 

 stones with pebble beds at base ... ... about 



2. Middle series (Sandgate and Hythe beds, Meyer = 

 greater part of Hythe beds, H.M. Geol. Survey). — 

 Ash-coloured sands and sandstones, Ferruginous 

 sands and sandy clay ... ... ... about 



1. Lower series (Atherfield clay). — Argillaceous beds with 

 concretions of shelly limestone towards the base, about 



FT.

Total 450—500 



Comparing these in their order with the Upware and Brickhill 

 beds, we find (1) the Atherfield clay quite dissimilar lithologically, 

 while its palaeontological relationship is by no means intimate. 

 Mr Meyer (who has kindly supplied me with revised copies of his 

 papers) records 120 species from these beds at East Shelford, 

 amongst which the following also occur as indigenous fossils at 

 Upware or Brickhill:

(2) In the next set of beds (the Sandgate and Hythe series of 

 Mr Meyer), fossils are much less numerous, but the list of species 

 shews strikingly the resemblance of its fauna to that of Upware. 

 Twenty-one species are recorded by Mr Meyer (loc. cit. pp. 8, 9), of 

 which the specific names of ten have been determined, and all these 

 ten species occur in the Upware and Brickhill deposits, namely : 



Ostrea macroptera, Sby. Waldheimia tamarindus, Sby.
