as constituted is quite unnatural. As far, too, as the occurrence 
of Rhynchonella spinosa is concerned I must doubt its being 
found in the Gryphea Grit. If we take Dr Wright’s zonal 
division we should have to draw the line between the Upper and 
Lower Division between the Oolite Marl and the Upper or Bastard 
Freestone. Not only does this seem a totally unnatural place, but 
I do not see that there are any sufficient reasons to support it. 
It would seem, however, that there is yet plenty of work to 
be done in order to correctly correlate the Inferior Oolite of 
the Cotteswolds with what is found in other places. 
Since the above was written I have been able during a 
recent visit to gain some information about one cutting of 
which I have made no mention in the previous part of this 
paper, and this is the cutting nearest to Bourton-on-the-Water 
Station, about one mile to the west of it. It consists of a 
fine yellow Micaceous Sand, very similar in appearance to what 
is known as the Cotteswold Sands, in which are embedded at 
all conceivable angles a large number of massive, pale-coloured 
blocks of Limestone, with some coarse ferruginous oolitic grains. 
The part of the cutting nearest to Bourton seems to be in a 
hopeless confusion, but as we get above the bridge we find that 
the beds seem to be more regular, and we are able to make out 
the following section :— 
SECTION XII. 
First Cutting West of Bourton-on-the-Water Station, above the Bridge, 
North side.

ary nodules, visible ... Sc ae ee se es 8 0 
Working further up the cutting we come toa further exposure 
of the bed No. 1, consisting of small, irregular slabs embedded 
in a much disturbed manner in a kind of debris, looking like the 
decay of the stone. No fossils could be found. Just before 
reaching the bridge over the river, a quarry on the north side 
of the line seems to exhibit more of a similar deposit. We
