This work contains a plate with the figure of the pj^gidia of Trilobites 

 and a fossil Crustacean. Fig. H is of a large pygidium of some species of 

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

 The author remarks " that he found the specimens during an excursion 

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

 of referring these fossils to the class Crustacea.
