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 aeries (Folkestone beds, Meyer, = Folkestone 

 beds, Sandgate beds and upper part of Hythe beds, 

 Geol. Survey). Sands, carstones, and shelly lime- 

 stones with pebble beds at base ... ... about 50 



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 



Lower series (Atherfield clay). Argillaceous beds with 

 concretions of shelly limestone towards the base, about 



250 

 160 



ware varieties. 



Total 450500 



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: 



Terebratula sella, Sby. I ^- , , , TT 

 Ithynchonella lata, d'Orb. f " 

 Exogyra Tombeckiana, d'Orb. 

 Ostrea Couloni, d'Orb. 

 Pecten Robinaldinus, d'Orb. 



,, orbicularis, Sby. 

 Perna Mulleti, Desh. 

 Area Carteroni, d'Orb. 

 Cardium subhillanum, Leym. 



(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. 



RhynchonellaCantabridgiensis,T)a.\. Exogyra Couloni, d'Orb. 

 Terebratula Meyeri, Walker? ,, Toinbeckiana, d'Orb.
