RADSTOCK SERIES OF THE SOMERSET AND BRISTOL COAL FIELD. 381 



Vers. d. Zwick. Schivarzkohl, pi. viii. figs. 1-3, and in his Vers. d. Zechst. u. 

 Rothl., pi. v. figs. 1, 2, the Somerset examples agree entirely. 



The nervation of this species is described by Gutbier as " nerves strong, 

 once bifurcated, in pairs, or fascicled (fiderig) according to the pinnulation."* 



In the almost entire pinnules of one of our specimens, one of the arms of 

 the dichotomously divided lateral veins usually divides again. 



Pec. Geinitzii has been united with Pee. pinnatijida by Weiss and Schimper, 

 and in this I have followed them. Such a course, however, makes it difficult 

 to reconcile the two figures given by Gutbier of the fruit of his Pec. pinnatijida t 

 with those he gives of the fruit of his Pec. Geinitzii, which is Asterocarpous !

Remarks. — Very rare. Only one specimen of this species has come under 

 my notice from the Radstock Series. 



From the structure of the fruit of this fern, Zeiller places it in his genus 

 Grand' Eurya, but from an examination of the type of Corynepteris, Baily, I 

 am led to conclude that Zeiller's Grand' Eurya is identical with Baily's 

 Corynepteris, and the latter, being the older generic name, is here adopted.
