graphed, as for example, the Brachiopoda, by Dr. Davidson ; the 

 Sponges, by Dr. Hinde ; the Blastoidea, by R. Etheridge and P. H. 

 Carpenter; the Merostomata, by Dr. Woodward. In others great 

 progress has been made as in the Foraminifera by Carpenter, Parker, 

 Jones, and Brady ; the Hydroida by Nicholson ; the Polyzoa, by 

 Busk and Vine ; the Trilobites by Salter and Woodward ; the Ento- 

 mostraca and Phj'llopoda, by Prof. Rupert Jones ; the Corals, by 

 Prof. Duncan ; the Echinoidea, by Wright ; the Decapod Crustacea, 

 by Bell and Woodward ; the Cephalopoda, by A. H. Foord ; and the 

 Tertiary Mollusca, by F. E. Edwards and Searles V. Wood. 



In Catalogues, serving as supplements to Morris, we have (1), 

 a complete "Catalogue of British Fossil Vertebrata," by Arthur 

 Smith Woodwai-d and C. Davies Sherborn, 1890, 8vo. pp. xxxv. and 

 396 ; larger by 51 pages than the space occupied by Morris for the 

 w^hole of the classes of Plantae and Vertebrata in 1854. (2), Fossils 

 of the British Islands Stratigraphically and Zoologically Arranged, 

 Vol. I. Paleozoic, by R. Etheridge, F.R.S., 4to. 1888, pp. 475, giving 

 6022 species from the Cambrian to the Permian. 



Mr. Etheridge tells us that Vol II. Mesozoic, and Vol. III. 

 Cainozoic, are Htill in MS., and, adding their contents to the Palaeozoic 

 volume already published, we have 18,000 species of British Fossils, 

 both Fauna and Flora, up to 1888. 



Morris's Catalogue, up to 1854, records a total of 8359 species ; 

 so that, according to Etheridge, there had been an increase of at 

 least 10,000 species in thirty-four years from 1854 to 1888. 



The only other catalogues which supplement Morris's Catalogue 

 are British Fossil Crustacea, by H. Woodward, F.R.S. (1877) ; Fossil 

 Foraminifera, by Prof. T. Rupert Jones, F.R.S. (1882) ; Palajozoic 

 Plants, by Robert Kidston, F.G.S. (1886) ; and lastly that of the 

 Edwards Eocene Mollusca, by Mr. R. B. Newton, now before us 

 (dated 25 July, 1891). 



This important work gives us a carefully prepared record of 1229 

 described species of British Eocene and Oligocene Mollusca, dis- 

 tributed in 255 genera ; 428 being Lamellibranchiata, 786 Gastero- 

 poda, and 15 Cephalopoda. 



In addition to the whole of the Edwards Collection, this volume 

 also contains a record of all the "types" of Eocene Mollusca con- 

 tained in the Bowerbank, Brandei", 15rown, Dixon. Gardner, Mantell, 

 Prestwich, Shrubsole, William Smith, Sowerby, Wetherell, and Wise 

 Collections, all preserved in the British Museum of Natural History. 

 Every species bears after it its author's name, the date when given, 

 and references to the principal works where it has been figured and 

 described, with its synonyms, and lastly the horizon and locality in 

 which it occurs. 



570 MS. names of species, proposed by F. E. Edwards, are also 

 given ; but as these have never been described, they cannot be 

 considered as of value, save as indicating that Mr. Edwards 

 believed they marked new and undescribed species. Many of 

 these names have been printed in various lists previous to the 

 publication of Mr. Newton's Catalogue ; and the author states (in
