Gastropod assemblages of late Carboniferous age (Namurian; Chokierian-Alportian) from the Morridge Formation at Pot Bank Quarry, Congleton Edge, Cheshire, contain 27 species, the most diverse gastropod fauna known from the Silesian of the southern UK. Chokierian sandstones yield a sparse assemblage of mainly high-spired Stegocoelia and bivalves, but flooding associated with the Hudsonoceras proteus marine band (basal Alportian) introduced a diverse invertebrate fauna in which the gastropod fraction is dominated by the bellerophontoideans Bellerophon, Retispira, Euphemites and Patellilabia, and the eotomarioid Angyomphalus. A later, previously unrecognized marine assemblage of probable Alportian age contains numerous small pleurotomariiform gastropods, but bellerophontoideans are less common and Angyomphalus is absent. In formal international usage the assemblages are of Pennsylvanian (Bashkirian Stage) age. One new genus Liraloron cornoviorum gen. et sp. nov. and the following new species are described: Retispira mowensis, Patellilabia britannica, Angyomphalus congletonensis, Neilsonia coatesi, N. ganneyica, Eirlysia ceramicorum, Meekospira acrolopha.
