The following table, mainly based on the " Chi'onologische Uebersicht cles Steinkohlen- 

 Ablagerungen in Europa", given by Dr. H. B. Geinitz in Geinitz, Fleck u. Hartig: Die 

 Steinkohlen Deutschlands, 4°, Miinchen, 1865, may serve to indicate the probable relative 

 age of the European species. The carboniferous beds are divided by him into five zones, 

 as follows, commencing at the base : I. Hauptzone der Lycopodiaceen ; II. der Sigillarien ; 

 III. der Calamiten ; IV. der Annularien ; V. der Farren. The two dyassic species enclosed 

 in brackets are those credited by Dr. E. Geinitz to this formation. Perhaps all the carbon- 

 iferous species should be classed together as upper carboniferous, excepting the three placed 

 under zone ii-iii ; and these to the middle carboniferous.
