VOL. XVI. (1) EXCURSION—-RODBOROUGH HILL 13 
Smith, Vincent A. Smith, W. Thompson, C. C. C. Young, Lieut.-Col. 
J. C. Duke, and Surg.-Major I. Newton; while Dr C. G. Cullis, 
F.G.S., came as a visitor. 
Mr Upton drew attention to an excavation that was being made at 
the Station (G.W.R.) at Stroud, in the Upper Lias. He said that 
these particular deposits occupied a stratigraphical position below the 
‘¢ Fish-Bed,” and above the Zeffena-Clays of the Upper Lias, and 
were known as the “ Paper-Shales.” He also stated that similar 
“« Paper-Shales” were exposed in the temporary section at King 
Street, Stroud, which he had described in a paper communicated 
to the Club.* 
The Members then walked along by the side of the canal as far as 
the Stroudwater Dye-Works, when they followed the path leading up 
on to Rodborough Hill. 
At the back of the old pound, Mr Upton pointed out the Pea-Grit, 
from which several fossils were obtained, including Zerebratula piso- 
litica, and Pseudoglossothyris simplex. The top of the Pea-Grit occurs 
here at an elevation of about 500 feet. Since the base of the Ragstone- 
Beds is near the 600 foot contour-line, it would appear that the Lower 
Freestone, Oolite Marl, and Upper Freestone are about one hundred 
feet thick. 
The Oolite Marl and Upper Freestone were seen in a quarry 
a little higher up that was fast becoming overgrown. Mr Upton said 
that it was here that Edwin Witchell collected many specimens of 
Nerinaa. 
In the next quarry visited, that near Mount Vernon, the top- 
portion of the Upper Freestone was visible, bored, and covered with 
oysters. 
Mr Upton made some general remarks on the section, referring 
particularly to his discovery, in some clayey material from the Upper 
Coral-Bed given him by Mr Richardson, of micro-brachiopods, similar 
to those that Charles Moore obtained from the ‘‘ Coralline-Beds” 
of Dundry Hill. In the absence of the President, Mr Upton then 
called upon Mr Richardson to supplement his remarks. 
Resting upon the Upper Freestone are thin representatives of the 
Lower Zrigonia- and Buckmani-Grits, and they are succeeded by the 
Upper Z7igonia-Grit. There are thus non-sequences between the 
Lower Zvigonia-Grit and the Upper Freestone, and between the 
Upper Z7igonta-Grit and the Buckmant-Grit. 
The Upper Z7igonia-Grit and the beds between it and the Fullers’ 
Earth may be conveniently designated the ‘‘ Top-Beds.” | Many 
geologists have collected fossils from them in the Stroud district ; but, 
with the exception of Witchell, none have given them any serious 
attention. 
Resting upon the Upper Z7vigonia-Grit at Rodborough Hill, 
Witchell discovered a Coral-Bed, concerning which he wrote, ‘‘ this 
bed, so far as is at present known, is confined to the neighbourhood
