A Retrospect of Palceontology for Forty Years. 101 



wrote ill 1901 upon Ammonites Bamsayanus from the Chalk of Chard- 

 «tock, Somerset ; A. euomphalus (1899) from the Lower Chalk, 

 near Lyme Kegis, collected by Dr. Rowe and Mr. C. D. Sherborn; 

 -and on a deformed Hoplites from the Gault of Folkestone. 

 Messrs. Foord & Crick wrote (in 1891) on the identity of 

 N. neocomiensis with JV. Deslongschampsianus from the Grey Chalk, 

 and on JV. elegans from the Lower Chalk and Greensand 

 (1890). Dr. Blackmore (in 1896) endeavoured to prove that 

 some of the bodies known as Aptychi, from the Chalk of Salisbury, 

 belonged to Belemnites. His conclusion was that (1) Aptychus 

 rngosus is the pro-ostracum of Belemnitella miicronata ; (2) Aptychus 

 leptophyllm is the same part of B. lanceolata ; (3) Aptychus Portlochii 

 is the pro-ostracum of B. quadrata ; (4:) the large, coarsely punctate 

 Aptychus from the Marsupite zone is the true Aptychus of Ammonites 

 leptophyllus. E. H. L. Schwarz wrote on Aptychus in Ammonites, 

 and supported the conclusion of S. P. Woodward (see The 

 Geologist, 1860) and H. Woodward (Geological Magazine, 

 1885) that the Aptychus is really equivalent to the calcified and 

 ■coalesced pair of dorsal arms which form the ' hood ' or operculum 

 in the living Nautilus. He has a second paper in 1895 on the shell- 

 structure in the Ammouoidea. In 1886 S. S. Buckmau wrote on the 

 lobe-line of Lias Ammonites, in 1887 and 1889 he described some 

 -Jurassic Ammonites, and in 1894 he discussed the species belonging 

 to the genus Cymhites from the Lower Lias of Lyme Eegis. E. T. 

 Newton wrote (in 1891) on Ammonites jurensis from the ironstone of 

 the Northampton Sands ; G. C. Crick on some Jurassic Cephalopoda 

 from Western Australia (1894), on Coccoteuthis hastiformis (1896) 

 and Acanthoteuthis speciosa (1897), both from the Lithographic Stone 

 of Solenhofen ; he pointed out that Nautilus truncatus, referred to the 

 Lias, really belongs to the Cornbrash ; he defined Ammonites calcar 

 from the Lower Oxfordian (in 1899), and Ammonites polygonus, 

 A. discoides, and Tmaegoceras (1902) from the Lias, and a Jurassic 

 Belemnite from Somaliland (1896). R. Tate discovered and 

 recorded the oldest British Belemnite [B. prematurus) from the 

 Lower Lias, Antrim (1869). A. H. Foord and G. C. Crick 

 figured in 1889 the muscular impressions of Coelonautilus 

 ^ariniferus ; described Pleuronautilus (1891); Veslinautilus and 

 Discites Mihernicus in 1893; described and figured Prolecanites, 

 Temnochilus from the Carboniferous of Cork, Ireland, in 1894; 

 and Nautilus rohustus from the Middle Lias of Les Moutiers, 

 Normandy, in 1902. G. C. Crick wrote on Goniaiites evolutus and 

 Nautilus tetragonus in 1896, and Ephippioceras (1900) ; and A. H. 

 Foord figured Acanthonautilus hispinosus (1897). F. R. Cowper Reed 

 ■described Pleuronautilus Scarlettensis, sp. nov.,from the Carboniferous 

 Limestone of the Isle of Man, in 1900. F. Roemer (1880) and 

 -J. E. Lee (in 1877) noticed the occurrence of Goniatites, etc., 

 in the Upper Devonian of Torbay. The late Professor H. A. 

 Nicholson gave, in 1872, a description and figure of Endoceras 

 jiroteiforme, Hall, from the Coniston series (Silurian), Skelgill Beck, 

 Ambleside. Dr. A. H. Foord (1887) wrote on Salter's genus
