Beyond the end of the cliff the coast suddenly recedes for some distance, and 

 nothing is seen till near the road are found, on the slope at the water's edge, some 

 flaggy, thin beds, quite unlike any of those recorded above. 



In this section it is to be noted that a large proportion of the lower beds are 

 brashy or irregular, and that the extent of the beds above is at the expense of 

 the Oxford Clay. Nevertheless, the first Ammonites represented in these beds are 

 A. koenigi, A. gowerianus and A. modiolaris. 



On the opposite side of the backwater several beds of the series can be 

 recognised in the scanty exposures; but beloAV them, on the northern side of 

 a small depression, thin, hard slabs are found, with small oysters and Lima 

 cardiiformis, like the typical beds of the Forest Marble, and farther on, doggery 

 yellow sands, like the Hinton Sands of Wilts. The contents of these latter 

 beds, though mapped as Cornbrash, are not therefore included in its fauna. 



2. East Fleet. — At the west end of the same range of Cornbrash we find 

 somewhat the same sort of beds exposed in separated parts. The first section 

 shows a downward succession with Macrocephalites in situ, beginning with the 

 basal Oxfordian beds at the far side, followed by :
