Of the organic remains contained in the Kimmeridge clay 

 of other parts of France little is known, except that the Gry- 

 phaea virgula is very abundant, and as characteristic of this 

 clay in that country as the Ostrea deltoidea is in England.^ 



M. Dufrenoy, describing some marls near Angouleme, gives 

 a list of the following fossils, but seems to refer them to the 

 upper part of the middle oolitic system, though they pass (de- 

 scent to the Pont de la Trouve) into marls full of the Gryphaea 

 virgula.f 

 Mya mandibulata. I Pholadomya acuticosta. 



depressa. I Trigonia clavellata. 



Pholadomya ovalis. j Natica sinuosa?? 



Besides the Gryphaea virgula contained abundantly in the 

 Kimmeridge clay of the environs of Cahors (South of France), 

 M. Dufrenoy mentions Terebratula perovalis. Lignite occurs 

 in this clay or marl near the Pont de Rodes.
