the North of England minea, are to be added Hydrohia, Bythinia, 

 Litlioglyplms, and Pisidium. Fish remains were often found. 

 Under these peculiar circumstances, from mineral veins and fis- 

 sures of different ages in the Carboniferous limestone, he had dis- 

 covered the oldest known Mammalia, about thirty-two species of fish, 

 and eight of Eeptilia, the oldest land and fresh-water Mollusca, and 

 numerous other remains, numbering in the whole about 267 species. 

 Mr. H. B. Brady, who had made a special examination of the 

 Foraminifera discovered by Mr. Moore, referred to the great interest 

 attaching to the genus Involutina, from the remarkable variety of 

 form his series presented, which had not hitherto been recognized in 

 connexion with the genus.

American Dinosauria. 



^' rriHE Twelfth Annual Eeport of the Board of Commissioners of 

 JL the Central Park (New York), for the year ending December 

 31, 1868," gives an account of the progress in the construction and 

 ornamentation of this well-designed and noble work, which is to 

 comprehend all that is agreeable to the healthy recreation of the 

 citizens and serviceable for their intellectual activity. The land- 

 scape-gardener, sculptor, and architect have already been success- 

 ful in carrying out designs, both of high art and of picturesque 

 rusticity. The Naturalist has his Zoological Garden, which is to be 

 useful also to the Cattle-breeder and the Acclimatization Society. 

 The Botanist, the Astronomer, and the Meteorologist are to find aids 

 here in their researches. The Antiquary and Historian will find a 

 Library and Museum. Nor is Geology lost sight of. The ground 

 itself of the Park is not destitute of geological interest; for the 

 labour of upwards of 200 rockmen and blasters, — required to quarry 

 and cut for ponds, rivulets, and roads, — open out sections worth look- 

 ing at : but the Commissioners determined to increase the value of 

 the Park in an educational point of view by availing themselves of 

 the scientific assistance of Mr. B. Waterhouse Hawkins, F.G.S., 

 well known as the talented constructor of the restorations of Extinct 

 Quadrupeds at the Crystal Palace, in modelling some of the great 

 American creatures of bygone times, of natural size and in life-like 

 form. This Eeport tells us of the already successful labours of Mr. 

 B. W. Hawkins, in visiting the Museums at Washington, New 

 Brunswick, Albany, New Haven, and Philadelphia, especially the 

 latter, studying these " rich storehouses of fossil treasures, of special 

 value for the purpose of illustrating the gigantic forms of life that 

 originally inhabited this Continent," and reproducing in iron, plaster, 

 and such like materials, the wonderfully bizarre and, as it were, 

 monstrous Dinosaurian forms, cousin-german to our Iguanodons, 

 Hylseosaurs, Scelidosaurs, Megalosaurs, and other Mesozoic Eeptiles. 

 Mr. Hawkins has chosen for his first American restorations Hadro-
