RADSTOCK SERIES OF THE SOMERSET AND BRISTOL COAL FIELD. 359 



of them, with one exception, misidentifications, I now find that the plants I 

 there placed under Nenr. cor data, L. & H. (?Brongt.), # should be referred to 

 Neur. Scheuchzeri, HofFm., and the ferns I placed under Neur. Scheuchzeri must- 

 be referred to Neur. macrophylla, Brongt. Further remarks will be found on 

 this subject under Neur. macrophylla, Brongt. 



My thanks are due to the Rev. H. H. Winwood, F.G.S., for facilities given 

 for figuring the fine specimen shown on PI. XXIII. fig. 1. 



Neur. Scheuchzeri occurs in several of the English coal fields. 



Localities : — Braysdown ; Radstock ; Upper Conygre ; Lower Conygre ; 

 Camerton ; Wellsway. 



Neuropteris flexuosa, Sternberg.

Neuropteris plicata, Lesqx., Goal Flora of Pennsyl., pi. x. figs. 1-4. 



Remarks. — Frequent. The plants figured as Neuropteris plicata by Les- 

 QUEREUX,t seem clearly referable to Neur. flexuosa, Sternb., whatever may be 

 the true value of Sternberg's species.! 



Var. rotundifolia.

Remarks. — This form has beeli found at Camerton, but it passes into Neur. 

 flexuosa, of which it can only be regarded as a varietal form. 



Localities : — Radstock ; Camerton ; Upper Conygre ; Lower Conygre.
