field, at least I can find no record of its occurrence elsewhere. 

 As pointed out by Lindley and Hutton its nearest Coal-measure 

 ally is the S. macilenta of the same authors, hut the Adiantides 

 antiquus of Stur's Culm Flora, Heft I., gives the best idea of 

 the gracefulness of the foliage. It has been found only in the 

 shale of the High-Main Seam at Killing-worth, and in the shale 

 above the Bensham Seam at Jarrow. M. Goppert, as usual with 

 him, changes the name to Adiantites concinnus. Such synonyms 

 are misleading, and ought to be avoided and suppressed.
