After many attempts to frame a concordance of the synonyms of 

 tliis well known Ecliinite, I have been obliged to give up in 

 despair, and even to displace their chronological order. In the 

 above catalogue, which might be swelled to three times its dimen- 

 sions by useless references to mere mentions of this species, I have 

 placed in first rank the references to Breyn and Leske, since to 

 them, and especially to the hgures of the last-named author, all 

 subsequent writers refer back. Next in order I have placed the 

 references (in lump) to Lamarck, Desmoulins, and Agassiz, authors 

 who have given catpJogues of species, and whose lists in this case, 

 according to my views, resolve themselves into a multiplicity of 

 names for the varieties of one thing, names too which cannot be well 

 reconciled with each other. Lastly, follow references to authors 

 most of whom have given original figures of the species, in one 

 variation or other, ranked in general in order of importance of 

 quotation rather than priority of date. All the figures cited in 

 these synonyms are preceded by a very good representation given by 

 Dr. Plot in his Natural History of Oxfordshire (1677), delineating 

 a flint cast of one of the ordinary forms of this Echinite. 



It is to be regretted that the original appellation given to this 

 fossil by Breyn, who styled it Echinocorys vulgaris, and 

 figured it much better than Leske did, was not retained. Now,
