Soc, vol. xv. p. 479, figs. 1 « to I /. This rcinarlviiblc plant, so charac- teristic of the whole IJevonian system at CJaspe, tilling many beds with its rhizomes, in the manner of the Stigmaria of the Coal measures, and preserved 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 steins are distin;j;uishable 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 Schoharie, New York, and at Akron, Ohio, in the Chemung group at Cascade Falls, and in the Catskill group at Jefferson. Most of the specimens are stems, which show the habit of growth very perfectly. They confirm my inference from the structure of the Gaspc 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 FuUenham, Schoharie, and in similar beds at Cazenovia and Cas
