This table shows at once that, of the fossil plants found in the Staffordian of the 

 Wyre Forest, the majority occur in the Radstockian Series, where, with a few 

 exceptions, they are all frequent or common. Under Pecopteris (Cyatheites) sp. 

 possibly more than one species occurs, but in these " Red Measures," even when the 

 outline of the pinnules is clearly exhibited, all trace of the nervation has almost in- 

 variably disappeared, and in this condition a critical determination is impossible. In 

 any case the " Pecopteris type" of fern is rare in the Staffordian of the Wyre Forest, 

 and in this it differs markedly from the occurrence of the genus in the Radstockian 

 Series, where they are extremely plentiful. 



On the other hand, there are several species that occur in the Staffordian of 

 the Wyre Forest which have not yet been found in the Radstockian, and which are 

 frequent or common in the Westphalian, such as Neuropteris tenuifolia Schl. sp., 

 Neuropteris Osmundas Artis sp., and Sphenophyllum cunei/olium Sternb. sp. Spheno-
