300 PROCEEDINGS OF THE GEOLOGICAL SOCIETY. [April 9, 



years ; the fossils are for the most part fragmentary and not well 

 preserved. 



The bed d contains — 



Cephalopoda. 



Ammonites opalinus, Rein. Nautilus inornatus, d'Orhig. 

 insignis, Schiibler. Belemnites breviformis, Voltz. 



Gasteropoda. 

 Turbo capitaneus, MUnst. 



Conchifera. 

 Myacites abductus, Phil. ? Gervillia Hartmanni, Munst. 



Brachiopoda. 

 Rhynchonella cynocephala, Rich. 



F contains many fossils in a fragmentary state, with a profusion of 

 small teeth of fishes. The limestone is bored hj FistulancB(!). 

 Belemnites abound in the bed. Belemnites breviformis, Voltz, and 

 Belemnites compressus, Voltz, are the prevailing forms. 



E contains shells in a fragmentary state ; but the specimens are 

 indeterminable ; many fragments of the spines of Echinoderms are 

 likewise strewed throughout this bed. 



G. The Upper Lias Clay is indicated by the outburst of springs 

 along the line of its junction with the sands : although this bed was 

 lately exposed in consequence of the falling away of a mass of debris, 

 still very few fossils were found ; I collected Ammonites bi/rons, 

 Brug. {Walcotii, Sow.), small specimens, Ammonites serpentinitSy 

 Schloth., Ammonites communis, Sow., Ammonites annulatus, Sow. 



Section III. — Beacon Hill near the Haresfield Station on the 

 Bristol and Birmingham Railway. 



Inferior Oolite. 



Ft. in. 



A. A close-grained freestone ; resembling the same bed at 



Leckhampton, but becoming rather flaggy in the upper 



part 15 



a', a close-grained yellow oolitic limestone, quarried for road- 

 mending ; much speckled with dendritical patches of 

 the peroxide of iron, and containing few fossils ; it mea- 

 sures about 12 



B. A yellowish sandy rock, separating into large blocks which 



contain fossililPerous nodules ; the fossils are in general 

 well preserved in this bed ; it is not used for any eco- 

 nomic purpose, and heaps of blocks lie close to the brown 

 micaceous sands * 1 8 



* In consequence of the position of these blocks, many supposed that they 

 came out of the so-called " Sands of the Inferior Oolite ;" and, as they contain 

 numerous fossils, it was said that such species had been collected from the sands. 

 The true position of these sandy stumbling-blocks is that now given in the 

 section.
