A Retrospect of Pakeontology for Forty Tears. 53 



was contributed by tbe late Dr. Wright on a new OpMurella nereidea 

 from Calciferous Grit, near Weymouth. The Rev. J. F. Blake noticed 

 a new Solaster (S. MurcMsoni) from the Lias, Yorkshire, closely 

 resembling Solaster moretonis ; and Dr. J. W. Gregory wrote on 

 Lindstromnster antiqna and Palceasterina Bonneyi from the Ludlow 

 beds of Shropshire, and Protaster brisingoides from Victoria, Australia. 



Crinoidea. — G. E. Roberts communicated a note on the 

 Mountain Limestone of Yorkshire and its Crinoids, and gave an 

 excellent chromo-lithographic plate of Woodocmms expanstis, found 

 near Richmond. J. Rofe monographed five genera of Crinoids 

 from the Mountain Limestone of Lancashire and Yorkshire, 

 giving a plate illustrating the structure of these forms ; he 

 also noticed the curious swellings on stems of Crinoids due to 

 small investing Corals, known as Gladochoniis, which he described 

 (1869). Ten years afterwards Nicholson and Etheridge redescribed 

 this coral. Mr. Rofe had a further paper on the raiaute structure 

 observable in the column of Pentacrinus, illustrated by excellent 

 figures, and in yet another paper he described the structure in the 

 stems of Rhodocrimis, Platycrinus, and Euri/ocrinus. Professor G. de 

 Koninck gives an account of new and remarkable Echinoderms 

 from British Palgeozoic rocks, figuring the genera Palcschinus, 

 Placocijstites, and Haplocrinus. E. Billings called attention to 

 Placocystites = Ateleocystites Huxleyi, from Dudley, vrhile H. Wood- 

 ward added a note and figures of the same, and in 1880 more fully 

 <liscussed and figui'ed this remarkable Cystidean. J. E. Lee noted 

 the occurrence of Capressocrinus in the Devonian Limestone near 

 Kingsteignton. Dr. F. A. Bather figured Merocrinus Salopics from 

 the Ordovician of Shropshire, Hapalocrimis Victorice, a new Silurian 

 ■Crinoid from Melbourne, Victoria; he added studies in Edrioasteroidea, 

 and gave an account of his search for Uintacrinus in England and 

 Westphalia. 



EoHiNOiDEA. — Professor P. Martin Duncan had a note on Galerites 

 ■albogalerus, Lamk. Dr. J. W. Gregory described Bhyncopygus Woodi 

 from the English Pliocene, and some Australian fossil Echinoderms, 

 Archceodiadema, a new genus of Liassic Echinoidea, and Egyptian 

 fossil Echinoderms. T. Roberts noticed two abnormal Cretaceous 

 Echinoids from the Lower Chalk of Cambridge. 



Annelida. — J. Hopkinson figured DexoUtes gracilis, a new 

 Silurian Annelid from Moffat ; H. A. Nicholson, two new species 

 of Tubicular Annelids; and R. Etheridge, jun., ^voie on British 

 ■Carboniferous Annelida and noticed some 25 species (1880). 



Crustacea. — The Crustacea have always occupied a very important 

 position in the pages of the Geological Magazine. Sir J. William 

 Dawson described and figured Homalonotus Dawsoni from the Upper 

 Silurian, Picton, and Anthrapalcemon Hilliana from the Carboni- 

 ferous of South Joggins, Nova Scotia. C. Speuce Bate figured 

 Archceastacits Willemcesii (which is really equivalent to Eryon 

 crassichelis) from the Lias of Lyme Regis. James Carter refers 

 to Orithopsis Bonneyi from the Upper Greensand of Charmouth, 

 mear Lyme Regis, Dorset ; and notices fossil Isopods from the
