280 MANUAL OF GEOLOGY. Crustacean fauna of this horizon—Ostracoda 7, Phyllopoda 7, Pcilo- poda i, and the Decapod Anthrapalcemon Grossarti. Polyzoa.—The Carboniferous Polyzoa as a group constitute by far the largest series in any division of the Palaeozoic rocks. Seventy eight species range through the three lower horizons of the Carboni ferous series, 64 belonging to the true Carboniferous Limestone, 28 to the Lower Limestone Shales, and 4 to the Calciferous series; not a single species passes to or occurs in the Yoredale, Millstone Grit, or either one of the three divisions of the Coal-measures. The whole group essentially belongs to the Calcareous rocks and shales at the base of the formation ; the large genera are—Ceriopora, Fenestella, G/auconome (Acanthocladia), and Polypora. Twenty other genera of zoological value occur, but the species are few in each genus (1 to 4). Actinostoma, Carinella, Diastopora, Goniocladia, Hemitrypa, Ptilo- pora, Rhabdomeson, Synocladia, and Vincularia are the chief genera. None of the Palaeozoic genera lived on or extended into the Mesozoic period, and the Fenestell become extinct in the Permian rocks. Calciferous Sandstone.—Arcliceopora nexilis, Ceriopora similis, Fenestella Morrisii, F. plebeia, F. tubercidato-carinata, and Glauco- nome gracilis appear to be all that are known in these lowest beds of the northern Carboniferous rocks. Lower Limestone Shales.—Thirteen genera and 28 species illus trate these shaly beds. The three chief genera are—Fenestella, Glau- conome, und Pustulipora; the remaining genera have only-i species each. Carboniferous Limestone.—Sixty-four species occur, belonging to 19 genera. The most important are—Fenestella with 25 species, Glauconome 8, Polypora 8, Rhabdomeson 3, Pustulipora 2, and Cerio pora 5 ; these, although poor in species, are highly characteristic. Amongst 13 remaining genera may be named Sulcoretepora, Syno cladia, Vincularia, Actinostoma, and Diastopora. No species passes to higher strata, or above the Carboniferous limestone. Arachnida.—The Arachnida have only been detected in the Lower Coal-measures. We have 4 species representing 3 genera— Architarbus subovalis, Eophrynus Prestvicii, Eoscorpius anglius, and E. carbonarius. E. carbonarivs and Architarbus are also American species, occurring in the Coal-measures of Illinois. The occurrence of two of the three genera in two areas so widely separated is signifi cant, with many other facts, of the probability of the continuity of land between Britain and America during the long period required for the deposition of the Coal-measures and the accumulation of coal. Myriapoda.—The 2 generaof ChilognathousMyriapoda, Euphoberia and Xylobius, which occur in our Coal-measures, are also American; this fact, together with the occurrence of the Arachnida, is strong presumptive evidence of continuity of land, densely covered with the peculiar flora known to have flourished during the Coal-measure period. We possess 3 species of Euphoberia—viz., E. anthrax, Salt., E. Brownii, and E. ferox. Dr. Dawson’s genus Xylobius, as well as
