LI. Richardson—Stratigraphical Position of Prosopon. 83 
Beds. As far north even as Nailsworth, near Stroud, it is quite easy 
to identify the equivalents of the Doulting Stone and Anabacia-Lime- 
stones; but the Doulting Stone has become much more rubbly and 
fossiliferous. At Scar Hill, Nailsworth, the top-portion of the beds, 
which I correlate with the -Anadacia-Limestones, are incipiently 
rubbly ; and, indeed, as these Doulting Beds are traced farther north 
they become as a whole more rubbly, until in the Clypeus-Grit of 
Cleeve Hill, to the north-east of Cheltenham, it is not easy to identify 
the equivalents of the Doulting Stone, Anabacia-Limestones, and 
Rubbly Beds, although it can be done with a tolerable degree of 
certainty. 
The quarry at Tor Hill may be divided, for descriptive purposes, 
into two portions—a lower, in which the massive oolitic limestones 
(which in this neighbourhood occur immediately below the Upper 
Trigonia-Grit) are worked ; and an upper, in which the Upper Zrigonza- 
Grit and rubble of higher beds was formerly quarried. 
The carapace of the Prosopon given to me by Mr. C. L. Walton was 
picked up; it was not found 7m sitt; but from the matrix I have no 
doubt whatever that it came from the Doulting Beds, and probably 
from that division of them which corresponds to the Anabacia-Limestones 
of the Doulting—Bath district. Unfortunately, however, only rubble 
of these beds caps the Tor-Hill section, but at Winner Hill—the 
next promontory to the south—there is a quarry in which a very 
satisfactory view of these top-beds is obtainable. The section is as 
follows :-—
