possibly by some fossiliferous deposits i-ecently discovered at 

 Waenrode, near Diest, the Coralline Crag corresponding very 

 closely with the Belgian Zone k Isocardia cor. 



II. With regard to the Coralline Crag : 



(a) That the junction of the Crag with the London Clay dips to 

 the N.N.E. 



(b) That no satisfactory evidence, either stratigrapliical or 

 palceontological, is forthcoming to show that any divisions to be 

 observed in this formation at Sutton are persistent at other 

 localities, and that species which have been tabulated as charac- 

 teristic of certain horizons are found also in other parts of the 

 Coralline Crag, and often in the Eed Crag as well. 



(c) That there is no evidence of any great subsidence, of deep- 

 sea conditions, of great changes of climate, or of the operation 

 of floating ice during the period. The climate was warmer than 

 that of Britain at the present day, more nearly approaching that of 

 the Mediterranean or the Azores. 



(d) That, so far from it being possible to separate this Crag into 

 eight zones, the twofold division hitherto adopted, into shelly 

 incoherent sands and indurated rock, can no longer be maintained, 

 the latter being merel}^ an altered condition of the former, as 

 proved by the discover}' of a section showing the two types passing 

 laterally into each other. 



(e) That, with the exception of the base, this Crag forms a con- 

 sistent and continuous whole, accumulated under similar conditions, 

 namely, in the form of submarine banks, piled up by currents in 

 sheltered situations like that known as the Turbot Bank off the 

 Antrim Coast and those at the south of the Isle of Man, where 

 Professor Herdman's " neritic " deposits occur. 



(/) That the (xerraan Ocean was less open to the north during 

 the Coralline Crag period than at present, but that it was connected 

 with the Atlantic by a channel over some part of the southern 

 counties of England. 



III. With regard to the Eed Crag : 



That it forms, with the exception of the Chillesford Beds and 

 "the unfossiliferous sands of the Crag," a continuous sequence of 

 deposits arranged horizontally, and not vertically. It was a marginal 

 accumulation of a sea slowly retreating to the north and east, as 

 shown by the gradually increasing number of northern mollusca met 

 with in this direction.
