In this paper a detailed description is given of the Inferior Oolite of 
the country between Doulting and Bath. The beds have been studied 
at different localities within the area by several geologists, but in 
most cases only the actual facts observable were recorded—there was 
little or no attempt at correlation. Now it is shown that there is 
within the area no Inferior Oolite deposit of earlier date than the 
Upper Zrigonia Grit—a deposit of Garantiane hemera. In the hills 
south of the Avon Valley at Bath, and as far south as a line drawn 
east and west through Carnicote, near Timsbury, this deposit rests 
upon the Midford Sands. South of this line, and between it and one 
similarly orientated about half a mile farther south, it rests upon the 
local Cephalopod Bed: here of greater antiquity than the ‘Sands’ 
(Midford) ; not younger, as in the case of the Cotteswold Cephalopod 
Bed. South of the latter line, the Upper Zrigonia Grit, often con- 
glomeratic, rests upon the non-arenaceous Liassic deposits, until in 
the more immediate neighbourhood of the Mendip Hills it is over- 
stepped by the Doulting Stone, which rests directly upon the 
well-planed, bored, and oyster-strewn surface of the Rhetic White 
Lias and the Carboniferous Limestone. On the south side of the 
Mendip Hills the Upper Zrigonia Grit comes in again. 
The Fullers’ Earth at Midford, at least the lower part, is of z7gzaq 
hemera. The intervening Inferior Oolite between it and the Upper 
Trigonia Grit may be thus divided, dated, and compared :—

In one appendix Mr. S. 8. Buckman indicates the deposits in 
Dorset equivalent to the above ; in another the late Mr. J. F. Walker 
and Mr. Richardson deal with the Brachiopoda of the Fullers’ Earth, 
naming seven new species; and in a third, Mr. Richardson describes 
anew Amberleya and Spirorbis. The micro-fauna of the Upper Coral 
Bed is dealt with by Mr. C. Upton, who obtained from material 
furnished him from Midford and Timsbury Sleight most of the micro- 
Brachiopeda such as were found by Charles Moore at Dundry Hill.

between the Rissingtons and Burford.” By Linsdall Richardson,

This paper is presented with the preceding, because there are 
several points of similarity between the two districts described. Both 
are near lines of country along which movements of upheaval were 
frequent during the time of formation of the Inferior Oolite rocks. 
In the Bath—Doulting district, above the Upper Zrigonia Grit 
(which rests upon the Upper Lias) over a restricted area, is the Dundry 
Freestone, and over a greater the Upper Coral Bed. Then come the
