318 MANUAL OF GEOLOGY. reptilia, occur in the marl slates of Durham, and in the corresponding Kupferschiefer in Germany. Seven genera and 14 species occur in the Rothliegende. Correlation of the British and German Permian Remains. As we have seen, neither the fauna nor flora of the British Per mian or Triassic rocks could be regarded as large or important. The Permian partakes largely of the Carboniferous type, of which it is the closing scene. Only no genera and 229 species are known in the British Permian series, and 107 genera and 199 species in the Triassic group, i.e., including the Rhtic. The flora of the Dyas is closely allied to that of the Carboniferous, and represents the last remains and traces of a vanishing epoch. The plant remains are mostly confined to the Rothliegende. Of the 18 genera and 26 species known, no less than 12 genera and 18 species belong to this horizon ; 16 are confined to it, while 5 genera and 6 species are met with in the marl slate. The two species occurring both in the Rothliegende and marl slate are Ullmania Brownii and Ullmannia Selagmoides. Though poor in forms of life, both the flora and fauna have a definite Palaeozoic character, closely allied to that of Carboniferous times. Of the 16 genera that occur 14 are Carboniferous, and the following 7 species pass up from that series or occur in both:—Catamites arenaceus, Cyclopteris dilatata, Lepido- dendron dilatatum, Neuropteris gigantea, Sphoenopteris latifolia, Trigo- nocarpum Noggerathi, and Sigillaria reniformis. No less than 60 species occur in the Permian rocks of Saxony. Upon the whole, the plants of the marl slate (base of the Magnesian Limestone in the North of England) differ considerably from those of the coal period, and the plants of the Rothliegende of Germany show, as in Britain, a close generic affinity with Carboniferous species. They include forms of Catamites (C. gigas), Asteroplujllites, Sphenop- teris, Alethopteris, Neuropteris, and Odontopteris, with also well-pre served silicified stems of tree-ferns (Psaronius 1 and Tubicaulis'). The conifer Walchia (W. piniformis) is specially characteristic both in Britain and Germany. According to M. Grand’ Eury, no less than 50 species of plants are common to the two floras. The following may be specially mentioned:— Catamites Suckowii, C. approximatus, Asterophyllites equisctiformis, A. myidus, Pecoptcris degans, Odontopte>-is schlotheimi, Sligmariaficoides, Cordaites borassifolius, &c. The most characteristic plants throughout the German Permian groups are Odontopteris obtusiloba. CaUipteris conferta, Walchia piniformis, and Catamites gigas. No one can doubt that the Permian flora presents many points of resem blance to and affinity with the Carboniferous. 2 The Zechstein group is characterised by a fauna corresponding to that of the Magnesian Limestone of England. Among the many fossils 1 Twenty-four species are described by Gbppert, "Ueber die Flora der Per- mischen Formation,” 1864-5. 2 Goppert: “ Ueber die fossile Flora, der silurischen, der devonischen, und unteren Kohlenformation oder sogenannten Uebergangsgebirges." 4to. 1859.
