Annelids. If we further consider this point we naturally come 
to the conclusion that there is a hiatus, and that beds were 
being deposited in other localities which are not represented 
in the Stroud area.. And so, in fact, is the case, as we can 
observe from a section of Leckhampton Hill,* where a bed 
which is absent at Stroud is called The Lower Trigonia Grit. 
In the section of Cleeve Hill, between the Upper Freestone 
and the bed with Gryphea sublobata, we have sands and a 
whole series of beds, absent at Stroud, most of which Dr 
Wright considers to be the equivalent of the Upper Flaggy 
Bastard Freestone, No. 4 of his section of Leckhampton Hill. 
There can be little doubt, I think, that the greater part of the 
beds shewn in the sections of the third cutting west of Bourton 
Station are the equivalents of the Lower Trigonia Grit of 
Leckhampton, and I should also imagine them to be the equiva- 
lents of the beds at Cleeve Hill, which occur between the sands 
and the Gryphza bed. These beds in the second cutting from 
Bourton are very much thinned out, and as we do not find the 
Gryphea in them, their upper boundary cannot well be detected. 
In the sections III. and IV. they consist of beds of Limestone 
in large masses, alternating with thin partings of Marl. These 
Limestone beds are extremely compact, stand out as large 
ledges along the sides of the cutting, and look as if they would 
make a fair though coarse building stone. One thing is 
especially noticeable in these sections, and that is the persistence 
of the two bands of Limestone above the sands; in section IL., 
they are two feet two inches thick, in section IIL., five feet, 
and in section IV. two feet eight inches. The other beds in 
these cuttings do not seem quite so easy to correlate. The 
Marly partings seem to be rather fossiliferous, and the Lime- 
stone somewhat so. The beds here yielded me some Ammonites 
in poor preservation, and I observed Cucullea, Ceromya, Belem- 
nites, Astarte, etc. They would probably well repay a more 
extended search than from the time at my disposal I was able 
to make. 
In bands of Limestone above, very similar to these, we 
find the Gryphea sublobata. It is merely the presence of
