I.—A Retrospect of Palæontology in the Last Forty Years

Extract

Polyzoa, etc.—Among our early contributors stands the well-known name of George Busk, author of a “Catalogue of Polyzoa in the British Museum” (1852–54) and a most valuable monograph on the “Polyzoa of the Crag” (Pal. Soc., 1859). Busk sent a paper (in 1866) to this Magazine on “Polyzoa from the London Clay of Highgate,” describing three genera and species new to science. Professor H. A. Nicholson wrote on Callopora in crassata from the Devonian of Canada; on Heterodictya from the Devonian of Ontario; and on the geological distribution of Solenopora compacta (1885). Professor Dr. Ferdinand Roemer (in 1880) recorded the genus Caunopora in the Devonian of South Devon. Robert Etheridge, jun. (1873), figured and described Carinella, a new genus from Carluke, Lanarkshire, and Bamipora from the Caradoc Beds of Corwen, North Wales. G. R. Vine discoursed on Carboniferous Polyzoa (in 1880); F. D. Longe on Oolitic Polyzoa (in 1881); and Dr. J. W. Gregory on some Jurassic species of Cheilostomata (in 1894).
