page 534 note 3 Mr. R. Kidston, F.G.S., in reply to my inquiry, gives me the following species as determined by him from the culm Asterocalamites scrobiculatus, Schlot. sp. (=Bornia radiata, Brong.) calamites Roemeri, Göpp. Sphenopteris, sp. nov. Lepidodendrom Rhodeanum (?) Lepidophloios, sp. Halonia (fruiting branch of Lepidophloios) Sigillaria(?) Stigmaria ficoides, Brong. (To thse I may add Dadoxylon, Sternb. (sternbergia), in Mr. Vicary's collection.) All these plants have (says Mr. kidston) a “Calciferous Sandstone” facies and are equivalent to the “Culm” of Germany.
