X The Upper Greensand is used in this case instead of the Cenomanian, for the 

 horizon at Blackdown, at which this fossil occurs, is probably the equivalent of the 

 Gault and not of the true Cenomanian. 



III. The Affinities of the Fauna. 



Mr. Topley recorded 11 species, of which Serpula filiformis is a 

 useless worm-tube, and two are excluded from the above list owing 

 to doubt as to the correctness of their identification. These are 

 Exogyra conica, a record which was probably based on a young 

 E. Couloni and Terebratula oblonga, which probably ought to have been 

 identified as Terebratella Fittoni; these two Brachiopods often, when 

 badly preserved, resemble one another somewhat closely. Mr.
