 but no plates are given :

In 1861 appeared the first edition of Hull's ' Coal-fields of Great Britain,' which 

 contained a plate on which was a figure of Aviculopecten papjraceus ; and later 

 editions with a somewhat altered plate appeared in 1873 aud 1881. 



In 1861, in the Memoir of the Geological Survey, " Iron Ores of Great Britain," 

 pt. iii, " The Iron Ores of South Wales," Mr. Salter gives a plate with figures of 

 ScMzodus carhonarius, Edmondla unioniformis, and Myacites sulcata from the 

 Eosser veins, and a short list of other marine Lamellibranchs from the same 

 horizon. This number contains the original description of that author's genus 

 Anthracomya, and illustrations of Anthracosia (Garhonicola) and Anthracoptera 

 (Naiadites). 



The next year, in the Geological Survey Memoir, ' The Geology of the Country 

 round Wigan,' with the definitions of the new genus Anthracoptera, and a figure 

 of Anthracosia {Carhoiiicola) rolusta, Mr. Salter gives a figure of Posidonia 

 Gihsoni, Brown. The generic reference is doubted, and it is stated that " a new 

 generic name will in all probability be required." 



In 1864, in the Memoir ' On the Geology of the Country round Oldham,' the same 

 writer figures Aviculopecten papyraceus, A. Jibrillosus, n. sp., and Ctenodonta, sp. 

 indet., from concretions in shales about 150 yards over the Great Mine Coal, 

 Ashton-under-Lyme. 



1862. In John Sleigh's 'Ancient History of Leek' is a section "On the 

 Geology of the Neighbourhood of Leek," by Thomas Wardle, F.G.S., with hsts of 

 Lamellibrancbiata found in the Carboniferous beds of that district. A plate is 

 given with illustrations of eleven genera and species from the Mountain Limestone, 

 and on another plate two genera from the Coal-measures. Nothing new is 

 figured or described. 



This list, somewhat revised by Mr. R. Etheridge, was reprinted in the appendix 

 to the Geological Survey Memoir, ' The Geology of the Country round Stock- 

 port, Macclesfield, Congleton, and Leek,' in 1866. 



1862. Winchell's paper, " Description of Fossils from the Marshall and Huron 

 groups of Michigan," was published in the ' Proceedings of the Academy of
