of the specimens in England they were submitted to Sir Richard Owen, who suggested the name (514) _Dendrerpeton acadianum_ and compared the remains with _Archegosaurus_. At the same meeting of the London Geological Society, Owen read a paper on a small amphibian (508) from the British Carboniferous which he named _Parabatrachus_. Subsequent discoveries have shown, however, that this form belongs among the fishes. At the meeting of the Geological Society held in the latter part of the same year Owen announced (509) further discoveries in the Nova Scotia coal beds. Hermann von Meyer (436), in 1857, described numerous stegocephalian remains from the upper Carboniferous of Germany. Dr. Jeffries Wyman, in the same year, described (639) a new form of amphibian from Linton, Ohio. This form he called _Raniceps lyelli_, but as the name _Raniceps_ had been preoccupied by Cuvier for a genus of gadid fishes, Wyman later (1868) changed the name to _Pelion_. This was the first form to be described from the locality at Linton, which has since yielded the remains of half a hundred species. Dawson (204), in 1859, made a further contribution to the fauna of Nova Scotia by the description of _Hylonomus_ and other species of _Dendrerpeton_ from the South Joggins deposits. Huxley (331), in 1862, described the genera _Loxomma_ and _Pholidogaster_ from the Carboniferous of Scotland. The same year Owen made a further contribution (514) to the fauna of the Nova Scotia beds, and Huxley (332) discussed the anatomy of _Anthracosaurus_ from Scotland. Marsh (404), in the next year, described, as an enaliosaurian, the interesting _Eosaurus acadianus_ from the Nova Scotia Coal Measures, basing the species on two vertebræ, apparently from the dorsal region. The vertebræ resemble the stereospondylous type, and Huxley (332) called attention to the similarity of these vertebræ to those of _Anthracosaurus_. Cope (105), in 1865, began his researches among the Coal Measures Amphibia of North America by the description of _Amphibamus grandiceps_ from the Mazon Creek shales of Illinois. Ten years later (123) he published a complete synopsis of the Carboniferous Amphibia of North America, with especial reference to the Linton, Ohio, species, illustrating many of the forms now known from Linton. Between the years 1865 and 1897, Cope published numerous papers (105-177) on the Amphibia of the Paleozoic, and to his researches is due a large part of our knowledge of these forms.
