1863.] HOLL INFERIOK OOLITE. 315 



C, Oolite-marl. f ee t. 



a. Pale-coloured, argillaceous limestone, with Tere- 



bratula fimbria, &c 3 to 4

D. Lower Freestone. 



The hill is capped by Gryphite-grit, with Gryphcea subloba, Desh. 



Thus, at Cleeve, a series of beds of very unstable character occupies 

 the interval between the top of the Oolite-marl and the base of the 

 Lower Ragstone, and represents the Upper Freestone of Leckhamp- 

 ton; but nowhere, in these beds in situ, do we find any of the fossils 

 of the Rolling Bank Quarry. Apart, however, from this negative 

 evidence that these beds are not on the same horizon as the Conchi- 

 ferous limestones of Dundry, we have the fact that this Lower Rag- 

 stone may be traced continuously from Dorsetshire, through Somer- 

 setshire, and along the escarpment of the Southern Cotteswolds, up 

 to the Trigonia-grits of Rodborough and Leckhampton Hills. 



The Rolling Bank Quarry has been excavated into an accumu- 

 lation of fallen debris which has collected at the foot of the oolitic 

 cliffs, and consists chiefly of Lower Ragstone ; and nearly all the 

 fossils that are found there belong to this subdivision. 



The Pea-grit. — The lowest member of the Inferior Oolite is the 

 Pisolite, or Pea-grit, which immediately underlies the Lower Free- 

 stone. This bed has been generally stated to thin out at dotting 

 Hill. Its southern limits have been somewhat more variously de- 

 fined. Its northern attenuation at dotting Hill is true, however, 

 only as regards its pisolitic structure, as the bed itself, although no 

 longer pisolitic, appears to underlie the Lower Freestone of the 

 Bredon outlier. 



Below the brow of the eastern extremity of the hill, above Aston, 

 Rhynchonella cynocephala, Rich., the small dwarfed variety similar 

 to the one which occurs at Wotton Underedge *, is found in de- 

 tached blocks of hard limestone ; but I have not been able to find 

 the bed in situ. This is the most northern locality at which this 

 fossil has hitherto been met with in the Cotteswold district. Further 

 round the hill, above Elmley Lodge, there is a bed of hard, yellow, 

 sandy limestone, some layers of which are full of fragments of Pen- 

 tacrinus and spines and plates of Echinoderms, with some fossils 

 entire. Terebratula plicata is the dominant fossil, but the valves 

 are usually separated. Still further on, beneath the ancient encamp- 

 ment of Bredon Tower, nearly 10 feet of this bed is exposed, 

 having the Lower Freestone resting upon it. On the surface of the 

 blocks, besides the fragments of Crinoidea and Ecliinoidea, are many 

 specimens of Cricopora verticillata, Mich.?, and other Bryozoa. 



To whatever position the grey and yellow limestone with JRhyn- 

 chonelJa cynocephala may be assignable, the bed above referred to 

 belongs, I think, to the Pea-grit. 



Towards the south the Pea-grit ceases to be pisolitic, or is only 



* The specimen, with part of the matrix, is in the author's cabinet.
