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

 Ton 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- 

 laris, C. punctcUus, C. xoorthii, etc, The name is used without a generic 

 description, and only indicated by the above named species.

 for several Enssian and Swedish Trilobites as defined by N. P. Angelin 

 (" Palfpont. Scand.," 1852, p. 2), with Calymene punctatus for its type.
