﻿Vol. 6 1.] RHvE'HC ROCKS AT BERROW HILL. 429' 



Despite the fact that several excavations were made in the 

 Upper Rhaetic, the only information which could be obtained is that 

 given in the record of the section. A creamy-yellow indurated 

 layer near the top resembled a certain variety of the Esther ia- 

 Bed, but neither Estheria nor Lycopodites could be detected in it. 



There are two small quarries at present open on the hill, but 

 water continually stands in the bottom. Details of the beds which 

 could be examined are given in the section. Prom the fields 

 between the kiln and the quarries most of the limestone has been 

 removed. 



It -is fortunate that it was possible to obtain exact measurements 

 of the component beds of the Lower Ehsetic Stage. Several points 

 will be at once commented upon : (1) the extreme tenuity of the 

 Pteria (Avicula)-contorta Zone and of the subjacent c Tea-Green 

 Marls' ; (2) the absence of a layer worthy of the name of ' Bone-Bed,' 

 and the feeble development of hard layers ; and (3) the scarcity of 

 Eheetic lamellibranchs. 



The nearest locality to Berrow Hill where the whole of the PJiaetic 

 Series may be studied is at Wainlode Cliff. 1 There the sequence of 

 deposits is (in descending order) as follows : —

There is no doubt that the bed numbered 7 in the Berrow-Hill 

 section corresponds to the similarly-notated stratum at Wainlode 

 Cliff ; and it will be observed how closely the several beds below that 

 horizon at the former locality correspond to similarly-notated deposits 

 at the latter. But, compared with Wainlode Cliff, the sequence of 

 deposits at Berrow Hill is not complete : rock, at least 3| feet thick, 

 is missing, because at the latter locality Bed 13 rests directly, with 

 perfect parallelism so far as can be seen, but non-sequentially, 

 upon the ' Tea-Green Marls.'
