116 Dr. H. Woodward — Note on Eiiphoheria ferox. 



3. There is a remarkable coincidence in the altitudes of the 

 Bagshot Pebble-bed at Bearwood and of the Pebble-bed at Easthamp- 

 stead Church and at Bracknell with a similar relation of the pebbles 

 to the sands ; ^ and I regard the beds of all these three localities as 

 occupying the same horizon and consisting of detritus from older 

 strata accumulated along the northern London Clay shore of the tidal 

 estuary, which covered over the earlier delta-deposits of the Middle 

 and Lower Bagshot, in which the old sand-dunes were for the most 

 part levelled down, while the Upper Bagshot Sands accumulated 

 as we now find them.

3. Eeconstructed material of bed 2 -with a few pebbles and flints as in the 



ordinary angular Drift 1 



2. Sti'oug ferruginous loamy sand -without very pronounced bedding (Bag- 

 shot Sand) 2 



I. Bed of well-rolled flints, completely rounded, densely packed in a grey- 



green sand in the upper portion, in a brown loamy sand below.

II. Light-grey clay, slightly laminated 1 



l\. Puce-coloured clay extremely tenacious and plastic 1

 The clay Z 2 appears to be a decolorized portion of H, somewhat reconstructed. It 

 is difficult to say if this is origiual London clay. Both these clays can be matched 

 exactly by well- defined clay-beds in the Wick Hill Section (Finchampstead), only 

 three miles distant, which are high up in the Middle Bagshot ; also by a clay (at 

 "Woodhay) of the Middle Division (Bristow, Mem. Geol. Survey, vol. iv. p. 330), for 

 specimens of which I am indebted to F. J. Bennett, Esq., F.G.S.

WHEN I noticed this species in the January Number of the 

 Geological Magazine (pp. 1-10, Plate I.), I had not pre- 

 pared a figure of the original specimen from the Hope Collection at 

 Oxford, which had been kindly lent me by Prof. J. 0. Westwood for 

 that purpose. 



1 See Q. J. G. S. August, 1885, and Proc. Geol. Assoc, vol. is. p. 223. Since 

 the statements here referred to have been published, they have been called in question 

 by the authors of a paper in the Quarterly Journal. The authors of that paper, from 

 insufficiency of observation, have misunderstood the Easthampstead section, and have 

 mistaken a mass of Quaternary drift at the surface for the pebble-bed which I 

 described as occurring at a horizon some 20 feet lower !
