No. 21 is most interesting for the fauna that it contains, (I 
have found that the fauna of each bed is more or less different 
to the others) which is more varied and abundant than that of 
any other beds. No 20 contains only T. submazillata, and being 
soft and decomposed in places, allows of its extraction. I have 
not found Tereb. curvifrons lower than No. 19, where it is fairly 
abundant. No.17 was identified by Mr Witchell as the equiva- 
lent of the Coral bed of the Stroud area. No. 16 is interesting 
for the great quantity of Rhynchonella subobsoleta which it 
contains. I have not found this shell at all lower, and the 
same remark applies to Tereb. fimbria, a fossil usually (but 
perhaps not correctly) supposed to characterise the whole of 
the Oolite Marl. The other beds are not particularly notice- 
‘able, except that I have observed 7. fimbria in bed 11, and that 
in No. 41 found a few small Rhynchonelle of the Rh. subangu- 
lata type. These shells are not yet named, but seem to mark a 
definite horizon some little way above the bed with Rhynchonella 
subobsoleta, for I have found them in the Stroud district in the 
same position. They usually go under the name of Rhynchonella 
cynocephola var., are of two or three Geis and could probably 
be well separated from that species. 
The height of this exposure of Oolite Marl above the level 
of the sea is remarkable. I have no exact datum, but it is 
probably between 750 and 800 feet; and I imagine that this is 
about level with the same bed on the escarpments of Cleeve 
and Leckhampton hills showing that during the universal 
drop of all the surrounding strata, making their general dip 
some degrees to the S.H., this bed retained its old position. 
Tf from the escarpment we had a uniform dip of less than two 
degrees, these beds should be at sea level. On the other hand 
if we are to suppose that the remaining beds of the Inferior 
Oolite with the Fullers Earth and Great Oolite capped this 
cutting, what an amount of denudation must have taken place. 
Does not the position of this bed seem to indicate that when 
the secondary strata were raised they were at first level, and 
that the depression which has caused them to dip 8. E. was of 
a somewhat later period ?
