12. Greenish compact Keuper marl forming the bottom of the pit. 
In this section the regular succession of the lower beds of the Lias 
and of the upper ones of the Rheetic formation is very clearly shown. 
The conglomerate takes exactly the place beneath the Ostrea-beds, 
and, if 1 am right in my determination, the precise position above 
the Hstheria-bed, which is proper to the White Lias or its admitted 
equivalent. At any rate, the mere fact of its occurrence under beds 
which cannot be other than the Ostrea-beds, must be taken as in- 
dubitable evidence of its position below the Hettangian series of beds. 
My own convictior is, that the conglomerate bed is the true repre- 
sentative of the Sutton Stone of Sutton and West, of the “ Guinea” 
bed of Binton and Grafton in Warwickshire, and of the White Lias 
of that county and the West of England. A comparison of the sec- 
tion at Stormy with the lower part of the section I have elsewhere 
given of the Binton Lias will show how considerable is the resem- 
blance between the twot. It will also point out the position of the 
bed numbered 10 as @orresponding with that of the Hstheria-bed. 
At another locality, Laleston, similar evidence to that of Stormy 
may be found. The churchy ard quarry is now nearly filled with 
rubbish, and the conglomerate is hidden; but the beds which are 
yet visible near the. top of the opening are unquestionably the 
Ostrea-beds, and their presence proves that at this place also the 
conglomerate is inferior to the Hettangian series {. 
I will now give an amended and comparative list of the Madre- 
poraria of the White Lias, Sutton Stone, Brocastle conglomerate, and 
of the St. Cassian beds; but I refrain from adding for comparison 
those from the Azzarola beds, because none of them have as yet been 
met with in this country.
