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 Olcni 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 truncatics Briinu, Agnos- 

 tus pisiformis Linne and Peltura scarabceoides Wahl.
