THE GEOLOGIST. 



recognized it as Eeptilian. Mr. Davis, of the British Museum, drew Mr. 

 Huxley's attention to it as being probably Arcliegosaurian. It is not 

 well preserved, but on careful study proves to be an amphibian allied 

 to Archegosaurus ; differing, however, from it in the form of the head, 

 the extent to which the ossification of the vertebral column has pro- 

 ceeded, and in the character of the dermal armour. This animal was 

 about 44 inches long. 



3. " On the Land Flora of the Devonian Period in ISTorth-eastern 

 America." By J. W. Dawson, LL.D., 'F.G.S. 



First noticing what v\ as formerly known of the Devonian Plant-remains 

 in the States of New York and Pennsylvania (Hall, Yanuxem, and 

 Hogers), in Gaspe (Logan), in New Brunswick and Maine (Gesner, E-obb, 

 Bennett, Hartt, Matthew, and Hitchcock), the author stated that with 

 Messrs. Hartt, Matthew, and others at St. John's, he had lately examined 

 the productive localities near that city, and is now enabled to add largely 

 to the account of the Devonian plants he had already published in the 

 'Canadian Naturalist,' vol. vi. 186L He now enumerates about 70 

 species (.32 genera) of plants as occurring in the Upper Devonian of 

 Pennsylvania, New Brunswick, Maine, New York, and Gaspe, in the 

 Middle Devonian of New York and Gaspe, and in the Lower Devonian 

 of Gaspe. Of these 70 species, two {PsilopJiyton princejjs and Cordaites 

 angustifolia) are referred also to the Upper Silurian of Gaspe; and 10 

 (not includiug these two) reappear in the Carboniferous strata. The 

 Devonian Plora maich resembles in general facies that of the Carboniferous 

 period. In the Lower Devonian series the underclays are filled with the 

 rhizomes of Fsilophyton, in the Upper Devonian with SigiUaricB and 

 Calamites (as in the Coal-measures j. The Devonian Flora is less per- 

 fectly preserved than that of the Coal-measures, and is ]}i'ohably as yet 

 very imperfectly known ; it presents more resemblance to the floras of the 

 Mesozoic period and of modern tropical and austral islands than the Coal- 

 plants present. The facies of the Devonian flora in North America 

 is very similar to that of the same period in Europe. 



Among the Devonian plants of North-east America, Dr. Dawson 

 recognizes an angiospermous dicotyledon {Syringoxylon mirahile, nov. gen. 

 et sp.), established on a fragment of fossil wood collected by Professor 

 James Hall from a limestone of the Upper Hamilton Group, at Eighteen- 

 mile Creek on Lake Erie. 



4. "On some Upper Eocene Fossils from the Isle of Wight." By 

 Professor Dr. F. Sandberger. In a Letter to W. J. Hamilton, Esq., For. 

 Sec. G.S. 



The rcfadt of Professor Sandberger's examination of a collection 

 of these fossils, carefully named by Mr. F. E. Edwards and forwarded by 

 Mr. Haniillon, has been to confirm him in his opinion that the upper 

 beds at Plemps'uwd, Isb of Wight, are the exact equivalent of the marine 

 beds at Weinhciiii, Jeurrcs. and Bergh {Reupelien ivfericur, of Dumont). 

 Tlio freshwater limeslone of Bombridge and Sconce appears to correspond 

 to the beds at Buxweilar (Aloace) and Abstadt (Baden) ; and the fossils 

 from Hoadon Hill and Colwoll Bay probably belong to the level of 

 Diimout's Tongr'toi infericur (Lethen and Westergeln) et siqjerieiir 

 (Manies superieur au gypse).
