ON THE TOP-BEDS OF THE INFERIOR OOLITE 
AT 
RODBOROUGH HILL, NEAR STROUD

In the neighbourhood of Stroud the Inferior-Oolite 
Series is divisible into two Stages, an Upper and a Lower. 
The Lower Stage comprises the Inferior-Oolite portion of 
the Cephalopod-Bed, the Sczsswm-Beds, Lower Limestone, 
Pea-Grit, Lower Freestone, Oolite Marl, and Upper Free- 
stone. The Pea-Grit and Oolite Marl soon thin out to 
the south of Stroud, and where the latter is present it is 
often difficult to separate it from the Upper Freestone. 
The Upper Stage comprises those of the Ragstone- 
Beds, which Mr S. S. Buckman, F.G.S., called for con- 
venience the “ Intervening-Beds,” and at Rodborough Hill 
the Upper Coral-Bed and CZ@yfeus-Grit—the last term 
covering for the present all the deposits between the 
Upper Coral-Bed and the Fullers’ Earth. 
The Cephalopod-Bed in the neighbourhood of Stroud has 
received considerable attention from Mr S. S. Buckman,’ 
and in earlier times from Dr T. Wright *-and others.? 
The limestones, now known as the Lower Limestone,
