The No. 6 in this section indicates the beds which are on 
the same horizon as the sandy beds in Section I. 
The connection of these sandy beds, and the Peagrit series, 
to the Upper Lias clay is shown much more clearly by the third 
cutting from Andoversford. On account of an upthrust of the 
Upper Lias clay causing the strata to assume an anticlinal 
position, we are able to examine the different strata from the 
Upper Lias by walking along the cutting. (See sketch).

It may very reasonably be concluded that bed No. 6 in the 
above section represents what is known as Upper Lias, and 
probably may be considered to be on about the horizon of the 
Commune-zone. The blue and yellow sands (Nos. 4-5), measuring 
altogether five feet, are the only representatives of the one- 
hundred-and-fifty feet or so of the Cotteswold sands exposed 
in the neighbourhood of Frocester. The line of Belemnites, and 
Rhynchonella cynocephala at the base of bed 3, may be looked 
upon as a faint indication of the so-called Cephalopoda-bed 
developed in the same locality; and it may probably be said | 
with safety that the base of bed 3 is on the horizon of the 
Opalinwm-zone. The rest of bed 3 may be regarded as roughly 
equivalent to the “‘sandy ferruginous limestone” of the Stroud 
district, and as representing the upper part of the Opalinum- 
zone, with perhaps the base of the Murchisone-zone. Bed 1
