This work was continued in several parts through this volume, but it is 

 only at p. 493, in the section called "De lapidibus insectiferis Scanices et 

 Gothicis," that the Trilobites are treated. We have there the Oleni of the 

 alum slate and Agnostus pisiformis. 



A separate edition of the work was printed at Stockholm and Leipzig,

This work contains rough woodcuts of Olenus truncatus Briinn, Agnos- 

 tus pisiformis Linne and Peltura scarabceoides Wahl.
