1 . At the top is a rubbly bed with fossils, but all in a very 

 imperfect state. 



2. Limestone having a purplish colour, apparently derived 

 from animal matter, irregularly bedded and containing a 

 great number of fossils, such as "Wenlock corals and Encrinites, 

 Spirifer radiatus, Orthis elegantula, &c. 



3. Purplish limestone, with numerous remains of Encri- 

 nites. 



4. Red and green schists, the base of which is not exposed. 



In this section all the beds dip to 45*^ east. Not far from 

 Tortworth Court is an anticlinal, a section of which is now and 

 then exposed (fig. 6). At a fortunate visit, when a small opening 

 was made, the following list of fossils was obtained : — 



Crania implicata (Sow.) 



Siluriana (Dav.) 



Spirifera sulcata (Dav.) 



plicatella. var. radiata (Dav.) 



Meristella didyma (Dalm ) 



Ehynchonella borealis (Schlok.) 

 navicula (Sow.) 

 Wilsoni (Sow.)
