This work contains a plate with the figure of the pygidia of Trilobites 

 and a fossil Crustacean. Fig. II is of a large i^ygidium of some species of 

 Asaphus. Fig. J is a cast in stone of a smaller species of the same geniis. 

 The author remarks " that he foimd the specimens during an exciirsion 

 along the shores of the Baltic Sea, in a red limestone." He has the merit 

 of referring these fossils to the class Crustacea.
