Soc., vol. xv. p. 479, figs. 1 a to 1 t. This remarkable plant, so charac- teristic of the whulo Devonian system at Gaspo, filling many beds with its rliizomcs, in the manner of the Stigmaria of the Coal measures, and prcHcrved in such abundance and perfection that it is much better know to us in its form, structure, and habit of growth than any other plant of the period, proves, as might have been anticipated, to have had a wide distribution in space as well as in time. Fragments of its stems are distinguishable in the sand- stones of Perry, and numerous fine specimens occur among the plants from New York State committed to me by Professor Hall. It occurs in the Hamilton group at Scl'.oharie, New York, and at Akron, Ohio, in the Chemung group at Cascade Falls, and in the Catskill group at Jefferson. Most of the sjjecimens are stems, which show the habit of growth very perfectly. They confirm my inference from the structure of the Gasp<j specimens that the plant was woody and rigid, as they often do not lie in one plane, but extend upward and downward in the manner of firm branches buried in sand. Most of the New York specimens seem to have been drifted; but groups of rhizomes, possibly in situ, occur in argillaceous sandstone from FuUenl am, Schoharie, and in similar beds at Cazenovia and Cascade Falls. These are the only instances presented by Professor Hall's collections of root-beds resembling those of Gaspe. In New York only the Upper and Middle Devonian have as yet aff
