The occurrence of plant-remains in the Lower Carboniferous rocks of England is so rare that the recent discovery of impressions in beds belonging to that series at Chepstow, by my friend and pupil Mr. M. P. Price, B.A., of Trinity College, Cambridge, is worthy of record. Mr. Price has obtained several examples of a Sphenopterid frond and other plant fragments from a bed of sandy shale of about 4 feet in thickness, lying between a red sandstone below and lime-stone beds above, in one of the Pen Moel quarries on the left bank of the Wye, immediately to the north of Chepstow. This locality is mentioned in Dr. Vaughan's recent paper on the palæontological sequence in the Carboniferous Limestone of the Bristol area. That author informs me that he refers the beds in question to the lower portion of the Seminula-zone (S1 of his classification) on the evidence of the fauna.
