Trigonia producta, T, angulata, Rhynchonella quadriplicata ?, &c. 
The basement-bed of the Inferior Oolite (Ragstones) at Fawler 
indicates that, in this southerly direction, the upper beds of the 
Inferior Oolite overlap the lower beds and rest directly on the 
Upper Lias, as is also the case near Burford (p. 145). 
The same basement-bed appears to be represented (as pointed 
out by Mr. Walford), in the pebbly beds with bored-stones, 
Trigonia, and Corals, at Hook Norton, and in the sections north 
of .Dunthrop, at Otley Hill, and at Sharpe's Hill. 
The cutting at Hook Norton, east of the tunnel, has afforded a 
good section of the strata, which have been described by Mr. T. 
Beesley, and more particularly by Mr. Walford, in whose com- 
pany I have had the opportunity of examining the beds, and on 
whose authority most of the fossils are enumerated.* The 
following is a summarized account of the beds :-

The Chipping Norton Limestone is no doubt represented in 
the I'-per strata, while lower down the Clypeus Grit and the 
Trigonia Grit of the Cotteswolds may be represented in point of 
time. (See Fig. 92, p. 329.)
