Cotteswolds or in the Bath-Doulting District. It occupies the 
stratigraphical position of the A nabacia-Limestones of the 
southern end of the South Cotteswolds 1 and the Bath-Doulting 
District ; 2 of the White Oolite of such localities as the Horton 
Rectory Quarry in the mid South Cotteswolds ; 3 and of the 
beds with marly layers, rich in micro-fossils, at Stinchcombe 
Hill, near Dursley. 4 
The Upper Trigonia- Grit rests directly on typical Pea-Grit, 
22 feet thick, the top portion of which is bored. At Kemble 
the “ Grit ” was separated from the Pea-Grit by Lower Free- 
stone 43 feet 6 inches thick, and at Tetbury by Lower Freestone 
19 feet thick. 
The Lower Limestone was an excellent example of an oolite, 
the ooliths being of very uniform size. 
The bottom bed of the Lower Limestone was a hard 
crystalline limestone-bed 8 inches thick, and another similar 
bed (4 inches thick) occurred at 1 foot 8 inches above it. In 
these beds radioles of echinoids and ossicles of isocrinoids were 
not uncommon. 
The discovery of typical Pea-Grit (22 feet thick) and Lower 
Limestone (21 feet 8 inches thick) below Shipton Moyne is 
interesting because this locality is very near to if not “ south- 
wards ” of the line a on Mr. S. S. Buckman’s “ sketch map 
showing the supposed relative position of land and water at 
the commencement of the Murchison(e-Zone i of the Inferior 
Oolite,” “ southwards ” of which was “ an area which received 
no deposit [during the hemera murchisonce\.” 6 
The Lower Limestone rested on a bed 4 inches thick which 
was full of specimens of Variamussium pumilum (Lamarck), 
Entolium demissum (Phillips) and Pseudomonotis sp. The 
lithic characters of this bed suggested its association with the 
Cotteswold Sands ; but the pectens incline one to group it with 
the Inferior Oolite.
