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 OUni of the 

 alum slate and Agnostus pisiformis.

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