In the first part of this work, in the list of fossils given on p. 22, Eduard 

 von Eichwald refers three species to Cryptonymus; a generic name which 

 he used in 1825 for an entirely different series of fossil Crustacea. In the 

 present work he substitutes the name for such species as Calymene vario- 

 larls, C. pitnctatus, C. ivorthii, etc, The name is used without a generic 

 description, and only indicated by the above named species.
