* I have given below the synonymes and references to this species, from all the works within my reach, and from 
others which I have not seen, on the authority of Burmeister. Perhaps no other single species has been so gene¬ 
rally cited in works upon this subject as the Calymene blumenbachii, to which we shall hereafter refer our species 
whether of the Trenton limestone or Niagara group.
