The beds are somewhat differently grouped by different ob- 
servers, but practically there are no marked divisions to be made 
in the Pea Grit Series at this locality.* E. Witchell has grouped 
the beds as followst :

On a higher horizon, a lenticular Coral Bed, 11 feet thick in 
places, was shown S.E. of Crickley Hill, resting on rubbly oolitic 
marls 3 or 4 feet thick, beneath which came the Pea Grit 
Series. 
The best known sections of the Inferior Oolite on the Cottes- 
wold Hills, are those at Leckhampton Hill. They have been 
described by numerous geologists, whose measurements and des- 
criptive details differ to some extent, on account of the varying 
nature of the beds.J The following is an account of the strata 
exposed in the quarries, though it does not include the highest 
beds present in the hill :
