The most abundant species in the Waldershare Series arc : — 



I Peoopteris irdltoni (Artis). 

 Cordaites principalis (Germar). 



Neuropteris scheuchzeri, Hoffni. 

 Neuropteris rarinervis, Bunb. 

 Annularia sphenophylloides (Zenker). 



Neuropteris ohliqua (Brongn.), Odontopteris lindleyana, Sternb., 

 and Mariopteris muricata var. nervosa (Brongn.) are not in- 

 frequent. 



In the Fredville Series, Aleiliopteris lonchitica (Schloth.) is the 

 only species that occurs frequently, but Neuropteris rarinervis, Bunb. 

 is not uncommon. 



The following table shows the distribution of the Kent species, 

 described here, in the Coal-Measures elsewhere in Britain : —

It will be seen from this list that several species have been 

 recorded from all four horizons. But, in such cases, they are nearly 

 always much more abundant on some horizons than on others. 

 Alethopteris lonchitica (Schloth.), for instance, is more characteristic 

 of the Lower and Middle Coal-Measures than of the higher series. 

 The majority of the species tabulated are either confined to the 

 Upper Coal-Measures and the Transition Series, o r are Middle and 

 Lower Coal-Measure plants which are also known to occur in the 

 Transition Series. All the plants have been already recorded from 

 the latter horizon, except, so far as I am aware, Eremopteris arte- 

 misicefolia (Sternb.) and the seed Carcliocarpus acutus, L. & H.
