* This species has previously been only found in the Middle Coal Measures in Britain, and the bed from which the 

 Staffordshire specimen was derived is high up in the Lower Coal Measures, and perhaps on a horizon with the lower 

 part of the Middle Coal Measures of other areas. When the three divisions — the Upper, the Middle, and the Lower 

 Coal Measures — are present in the same coal field, the exact position of the dividing line is often a matter of individual 

 opinion, though the different fades of the fossils of the various divisions, when taken as a whole, is characteristic of each.
