LOWER OOLITIC KOCKS OF ENGLAND : 
The late Joshua Brown of Cirencester, collected many Corals 
from this quarry, including Convexastrcea Waltoni, Isastrcea gibbosa, 
I. limitata, Thamnastr&a Lyelli, &c. Mr. Tomes compares the 
Coral-bed with that on Farley Down near Bath.* 
On the north side of the Tetbury road, a little more than 
2 miles from Cirencester, beyond the old pit known as Jarvis' 
Quarry, we find the following section : 
Great Oolite. 
(Upper Division) <( 
Kemble Beds. 
Bubble and false-bedded shelly oolite, 
with Ostrea - 
Marly and shelly clay with Ostrea 
(abundant), and Terebratula - 
Shelly and oolitic limestones with Fish- 
remains, Ostrea, Pccten vagans, &c. 
(stone worked for building-purposes 
and road-metal) 
Clay -band .... 
Marly and shelly oolitic limestone. 
Fossil Bed ; with Terebratula maxil~ 
lata, Lima cardiiformis, &c - 
Shelly oolitic limestones, " Soft Cockly 
Beds " ... about 
FT. IN. 

The top beds are evidently the same as those that occur at the 
base of the Bradford Clay at Jarvis' old quarry, where they 
attain a thickness of 12 feet. The above beds compare well with 
those seen near Kemble. I obtained the following fossils from 
them : 
Crocodilian tooth. 
Hybodus. 
Mesodon (Pycnodus). 
Strophodus. 
Corbula ? 
Lima cardiiformis (abundant). 
duplicata. 
impressa. 
strigillata. 
Opis? 
Ostrea. 
Pecten annulatus. 
lens. 
peregrinus ? 
vagans (abundant). 
Unicardium varicosum. 
Terebratula muxillata. 
Echinobrissus-Griesbachi. 
Isastrsea limitata. 
By the College Farm at Cirencester the following beds were 
exposed at the Lime-kiln : 
Great Oolite 
(Upper Division) 
f Bubbly oolite. 
| Bubbly marl and pale limestone with 
Natica intermedia, N. Stricklandi ? 
Trochotoma dbtusa, Mytilus sublcevis, 
Homomya Vezelayi, Lima cardii- 
formis, Terebratula maxillata, and 
Pygurus. 
False-bedded oolitiu limestone, irregu- 
lar. 
FT. IN. 
Kemble Beds and <( Thin-bedded oolite and sandy layers 
White Limestone. 
Oolitic limestone 
Bubbly and marly beds - 1 to 
Compact oolitic coral-limestone, with 
in the upper part (for about 1 foot) 
irregular ferruginous and earthy 
veins, causing cavities as in the Dag- 
ham stone. Convexastrcea Waltoni ? 
and Stylina - 
_0olites with sandy partings in places -
