BIBLIOGRAPHICAL SKETCH. 51 



Yoredale Rocks, and Millstone-grit of North Derbyshire," ' Mem. Geol. Siirv.,' 

 Appendix I, is a list of the Carboniferous Limestone fossils, revised and added to 

 by G. Sharman and E. T. Newton. A table is given in parallel columns showing 

 the various localities at which each fossil occurs, but no horizons are indicated. 

 A special column is given to the occurrences of the fossils in the Carboniferous 

 Limestone of Staffordshire for the sake of comparison. No new forms are noted. 



1888. On the 8th of December, 1887, John Young, LL.D., read a paper before 

 the Geological Society of Glasgow, published in the ' Transactions,' vol. viii, 

 part ii, 1888, p. 291, entitled "Notes on the Scottish Carboniferous Genera of 

 the Molluscan Family Anatinidse." He refers Myacites, Leptodomns, Sanguino- 

 lites, Edmo7idia, and Cardiomorplia to this family, and he discusses at some length the 

 affinities of each. The genus Sedgioickia, though not occurring in Western- 

 Scottish Carboniferous beds, is also mentioned and referred to the same family. 

 He remarks on the large number of species which have been described and named, 

 and thinks that a careful review would very greatly curtail the list. 



1888. A complete list of the genera and species of British Carboniferous 

 Lamellibranchs, with, in certain cases, synonyms, is contained in the ' Fossils of the 

 British Islands ; ' vol. i, " Palgeozoic, with Appendix brought down to end of 1886," 

 by Robt. Etheridge, sen. No localities are mentioned, but references are given in 

 almost every case. No new species or genera are described. 



1888. In the ' Proceedings of the Academy of Natural Sciences of Philadelphia ' 

 for 1888, is a paper by C. R. Keyes, " On the Fauna of the Lower Coal-measm^es 

 of Central Iowa." Nine Lamellibranchs are enumerated, pp. 232 — 4, but no new 

 ones are described. 



1889. In S. A. Miller's ' North-American Geology and Palasontology,' dated 

 1889, is a brief classification of the American rocks, including the Carboniferous, 

 and a full list of the Paleeozoic fossils of North America, arranged with their genera 

 and species alphabetically, under the sub-kingdoms, with the synonyms printed in 

 italics. Whenever possible a woodcut is given of the type species, and references 

 are given to the original publication in which each species was described or figured, 

 A previous volume was published in 1877 by this author, entitled ' The American 

 Paleozoic Fossils.' This work is quoted by de Koninck. 



1890. Mr. John Ward, in his paper on the " Geology of the North Staffordshire 

 Coal-fields," ' Transactions of the North Staffordshire Institute of Mining and 

 Mechanical Engineers,' vol. x, gives lists of the marine Lamellibranchs which occur 

 in two bands, one above the Gin Mine or Golden Twist Coal, and the other above 

 the Bay Coal of Longton ; and also notes Aviculopecfen papyraceiis from Yoredale 

 and Coal-measure beds, A. aJternatus, A. fibrilosus, and Posidom.onija Gibsoni^ 

 from Yoredale beds, and Schizodus from below the Four-foot Coal, Werrington. 



Anthracoriuja lanceolata is erroneously described as ModioJa Ufhodomoides,
