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 Gallopora incrassata 

 from the Devonian of Canada ; ou Meterodictya from the Devonian 

 of Ontario ; and on the geological distribution of Solenopora 

 compacta (1885). Professor Dr. Ferdinand Eoemer (in 1880) 

 recorded the genus C'aunopora in the Devonian of South Devon. 

 Eobert Etheridge, jun. (1873), figured and described Carinella, 

 a new genus from Carluke, Lanarkshire, and Bamipora from the 

 Caradoc Beds of Corwen, North Wales. G. E. 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). 



Brachiopoda. — The historian of the Brachiopoda, Dr. Thomas 

 Davidson, who finished his great work in 1885, and who was 

 equally facile with pencil and pen, was a large contributor to the 

 pages of our journal for twenty years. His great monograph on 

 British Brachiopoda, published by the Palaeontographical Society, 

 fills five large quarto volumes, illustrated by over 200 plates drawn 

 by the author's own hands. He was author of the article 

 JBrachiopoda for the " EncyclopEsdia Britannica," and monographed 

 the specimens collected by the "Challenger" expedition. He wrote 

 in this Magazine on the genus Thecidium (1864) ; on perforate 

 and imperforate Brachiopoda (1867) ; on the earliest forms of 

 Brachiopoda in British Palgeozoic rocks (1868) ; Italian Tertiary 

 Brachiopoda (1870) ; Tertiary species from Belgium, and on the 

 genus Forambonites (1874) ; Scottish Silurian Brachiopoda, and on 

 "What is a Brachiopod ? " (1877); on those of the Boulonnais 

 (1878) ; on Lower Llandeilo forms from Brittany (1880) ; on
