In the following lists I have given the equivalents of the Horton series and Millstone-grit series as thoy appear to me to be settled by stratigraphy and fossils:â 1. Equivalents of the Lower Carboniferous Cual-Measures or Horton iSeries. (1.) The Vespertine Group of Rogers in Pennsylvania. (2.) Tile Kinderhook CJroup of Worthen in Illinois. (3.) The Marshall Group of Winchell in Michigan. (4.) The Wavcrley Sandstone (in part) of Ohio. (5.) The Lower or False Coal-measures of Virginia. (G.) The Caleiferous Sandstones of M'Laren, or Tweedian Group of Tate in Scotland.* (7.) The Carboniferous Slate and Coomhala Grits of Jukes in Ireland. (8.) The Culm and Culm Graywacke of Germany. (9.) The Graywacke or Lower Coal-measures of the Vosgcs, as described by Scliimper. (10.) The Older Coal Formation of the Ural, as described by Eichwald. (11.) The so-called " Ursa Stago " of Heer includes this, but he has united it with Devonian beds, so that the name cannot be used except for the local development of these beds at Bear Island, Spitzbcrgcn. All of the above groups of rocks arc characterized by the preva- lence of Lrpidodendra of the type of L. corrujatuni, L. Velthei- inianum, and L. Glincammi, and also of the type of L. telragonuin of Sternberg (Bergeria of some authors),-J- pines of the sub-genus Pitus of Witham, Palaioxi/lon of Brongniart, and peculiar ferns of the genera Ci/clopteris, Cardiopteris, and Sphenopteris, In all the regions above referred to they form the natural base of the great Carboniferous system. * Some attention has recently been given to tiiese beds in England and Scotland by Oeikie, Hull, Lebour, and others, a
