with anywhere in the section, except very near the base of K 1? 

 where a definite grit-band occurs. Some of the calcareous and 

 shaly beds at various levels in K x contain a good deal of sandy 

 material. 



(C) Argillaceous Rocks. 



These are practically confined to : — 



(a) The K beds, where shales are very strongly developed and contain, in 



places, numerous ostracods. 



(b) Z 2 and the top of S2, where the thin bands of limestone are separated 



by appreciable shaly partings. 



Shaly partings occur also in connexion with the prominent rib 

 of rock which is taken as marking the line of division between 

 S x and S 2 .

1 It gives me the utmost pleasure to acknowledge the very valuable 

 assistance that Mr. B. G. Carruthers, F.G.S., of H.M. Geological Survey, has 

 so ungrudgingly rendered in the identification and study of the Burrington 

 corals ; without his aid, the faunal lists and palasontological section would 

 have been far less complete.
