FOSSIL FLORA OF THE STAFFORDSHIRE COAL FIELDS. 115 



the name given above, as since that provisional name was proposed I now feel satisfied 

 that the fossils belong to the genus Neuropteris. 



Of the specimens figured by the Abbe Carpentier, that given on his pi. xvi. fig. 1 

 at b, which he refers to Potoniea adiantiformis Zeiller, and those he gives as doubtful 

 at figs. 2 and 3, are certainly the same plant as that described here. 



In Potoniea Zeiller * the pinnules are cuneate like those of Adiantum, with delicate 

 foot -stalks, not cyclopteroid and attached to a very thick rachis ; and, more important, 

 the sporangia in Potoniea seem to be confined to the margins, not covering the whole 

 upper surface of the pinnules as in Neuropteris Carpentieri, where the sporangial 

 pinnules must have had a very similar appearance to a hair-brush if we turn it upside 

 down, the bristles representing the sporangia and the handle the petiole. 



Neuropteris Carpentieri in some states of preservation has a slight resemblance to 

 Dictyothalamus Schrollianus Gopp.,t but the apparently distichous arrangement of the 

 "buds" on that fossil to a common axis indicates an entirely different class of plant, 

 and one which does not appear to have any affinity to the Pteridosperms with which 

 undoubtedly Neuropteris Carpentieri has. 



All the figured specimens have been collected by Mr H. W. Hughes, F.G.S. 



Horizon and Localities. — Ten-foot Ironstone Measures: Clayscroft Openwork, 

 Coseley, near Dudley ; Ettingshall. 



Neuropteris sp. 



Remarks. — Specimens of a Neuropteris have been found at Sandwell by Mr H. W. 

 Hughes which have somewhat the form of Neuropteris tenuifolia, but with a much 

 wider nervation and the pinnules more distant. 



Horizon and Locality.- — Blue Measures, above Brooch Coal : Jubilee Pit, Sandwell 

 Park, West Bromwich.
