* I place this species, as synonymous with C. fibrosa, with a query, because C. 

 fibrosa has never been reported above the upper greensand in England or France. 

 Should it prove identical, as Messrs. Meek and Hayden think, it will be one of 

 the rare instances of a species peculiar to a certain deposit in one locality, being 

 found in another deposit in a distant locality.
