Sphenopteris (allied to furcata Brongt.). 

 Middle Coal Measures. 



Hor. — Stanley Main Coal. Loc. — Wakefield. 



Remarks. — The specimens placed here are very 

 fragmentary but shew indications of the fructification, which 

 is situated at the extremities of the pinnule segments. The 

 state of preservation of the fossils does not admit of any 

 minute description of this interesting fructification. It is 

 to be hoped that further collecting will reveal better-pre- 

 served examples.

Middle Coal Measures. 



Hor. — Barnsley Thick Coal. Locs. — Woolley Colliery, 

 Darton, near Barnsley (Hemingway). Monckton Main 

 Colliery, near Barnsley (Hemingway). East Gawber 

 Colliery, near Barnsley (Hemingway). 



Remarks. — Some very fine fruiting specimens of Stur's 

 Hapalopteris schatzlarensis have been collected by Mr, 

 Hemingway. On some of these the structure of the spor- 

 angia is very clearly exhibited. The sporangia are oval 

 exannulate, with walls composed of slightly elongated cells 

 and are situated singly, or two or three together, at the 

 extremities of the pinnule cutting. The fern must be 

 placed in Renatdtia as this genus was founded some months 

 prior to Hapalopteris Stur. 



I now think that the fern I identified with doubt, as 

 Sphenopteris schiltzei Stur sp., from the Lanarkshire Coal 



Geol. Trans. Y.N.U., iS88 (pub. iS^o).
