1036 DR R. KIDSTON, MR T. C. CANTRILL, AND MR E. E. L. DIXON. 



The fossil plants of the Etruria Marl Group are almost entirely unknown, as these 

 rocks have proved very barren of fossils. But that the beds under discussion are 

 not referable to the Etruria Marls is shown by the very close agreement of the 

 species collected from the Wyre Forest with those typical of the Radstockian 

 Series. 



It is therefore seen that the suggestion made by Cantrill, Prof. Lapworth 

 and Prof. Watts, * that the Sulphur Coals belonged to the Newcastle Group or 

 Halesowen Sandstone, or the more general belief of Messrs Meachem and Russ, 

 that the Halesowen Sandstone Group occurred in the Wyre Forest Coal Field, is 

 quite correct. 



We are therefore unable to accept the view expressed by Dr Arber that " the 

 Sulphur Coal Series of the Wyre Forest belongs to the same horizon as the Red 

 Clay group t of South Staffordshire, and may be the actual representative of 

 that very series"; and further, "if the Halesowen Sandstone Series occurs in the 

 Wyre Forest the beds must be thin, for there does not appear to be any great 

 development there of grey arenaceous rocks above the coals, which lie at the base 

 of the series." \ 



The Keele Group of the Radstockian Series is present in the Forest of Wyre, but 

 the only plant derived from it is the Sigillaria Brardi Brongt. var. denudata 

 Gopp. pro sp.

§ I unite with this species the Sphenopteris (Diplothmema) Schumanni Stur (Die Fame : Curb. Flora d. Schatx. 

 Schichten, p. 352, pi. lxv, fig. 2) and the Sphenopteris striata Gothan (" Oberschlesische Steinkohlenflora," i Theil, p. 24, 

 pi. v, figs. 3, 3rt, pi. vi, figs. 3, 3a, Abhandl. Geol. Landesanstalt, Neue Folge, Heft 75, 1913). The distinctive characters 

 of the latter are, I believe, entirely due to the condition of preservation of the specimens. Both forms occur here.
