Remains in the Oolite Series ofEnglaJid and France. 265 



M. Elie de Beaumont notices numerous polypifers and 

 echinital spines in the coral rag and Oxford oolite of Bur- 

 gundy. The same rocks also contain large Nerineae, Deci- 

 ceratae, large fibrous shells, dentated oysters, striated Tere- 

 bratulse, vegetable impressions, &c.* 



M. Dufrenoy describes rocks, which he considers equiva- 

 lent to coral rag, near Marthon and Rochefoucault, and states 

 that they contain an abundance of polypifers of the same kinds 

 as those of the coral rag, and numerous crinoidal remains.f 



The reader will perceive that, though the coral rag and 

 Oxford oolite occur in numerous parts of England and France, 

 their organic remains have not been well determined, excepting 

 by Mr. Phillips in Yorkshire. The other published lists are 

 exceedingly defective, more particularly in the catalogue of the 

 polypifers from which the rock has received one of its names. 

 The following list, therefore, of organic remains which have 

 been noticed in more than one of the localities, will be exceed- 

 ingly meagre; whereas if the polypifers had been better known, 

 it would have been quite the contrary.

Astraea favosioides is the only polypifer among the nume- 

 rous species contained in the coral rag, which has been pro- 

 bably determined in more than one locality, unless, indeed, 

 we except the Caryophyllia stated to resemble C. caespitosa of 

 Ellis and Solander.
