beds may be traced in the next quarry, (5) where they are seen 
near the bottom of the Section. They are about 15 feet 
below the Pea-grit, so that they are near the middle of the 
white portion of the Lower Limestone. 
Mr 8. S. Buckman has recently discovered and pointed out 
to me a similar bed at Randwick hill, in the Lower Limestone, 
about six feet below the Pea-grit, and therefore somewhat 
higher than at Selsley. The beds are thicker, and the pebbles 
appear to be more sparingly distributed at the base, and more 
angular than those above. 
At the junction of the upper or ferruginous portion of the 
Lower Limestone with the lower I have discovered a small 
fragment of a Nerinea, much worn, as if it had been brought 
some distance, but its internal structure is sufficiently pre- 
served to enable me to assign it to WN. pisolitica, found in the 
Pea-grit, or an allied species, having a similar internal structure. 
As the bed in which it was found is 10 feet below the Pea-grit, 
this Nerinea must be one of the earliest of its race at present 
known. In the bed next above, and not many inches higher, I 
discovered a fragment of another species of Nerinea, and in 
the adjoining quarry, at about the same level, I discovered 
another fragment belonging to the first-mentioned species. 
These fossils confirm the suggestion which I made in a recent 
paper on the Nerinea that there might be other rocks anterior in 
time to the Pea-grit in which it would be found. In addition 
to the Nerineas I have obtained a few fragments of shells and 
one example of Trigonia costata, but all are much worn. In 
fact the Lower Limestone beds are largely composed of detritus 
of Encrinites, broken spines of Hchini and worn shells, with small 
fragments of Coral and Quartz pebbles sparingly distributed, 
the whole intermixed with small white Oolite granules. 
In the quarry (No. 5) the upper beds of the Lower Limestone 
have the Pea-grit overlying them. It consists of a bed of 
Pisolitic Limestone, three feet thick, with a band of Marl and 
loose Pisolites above, about two feet thick. The Pisolites are 
much smaller than at Birdlip. I have found the following 
fossils in these beds, which are common to the Pea-grit :—
