Two anthracosiid assemblages from the upper part of the lenisulcata Zone of the Leinster (Castle-comer) Coalfield, Ireland, one from Co. Tipperary (Slieveardagh) Coalfield, Ireland, and one from Glynneath, Glamorgan, South Wales, have been measured and are extensively illustrated. The results bear on relationships between the morphological species Carbonicola extenuata, C. crispa and C. proximo Eagar, C. extiina, and C. pontifex spp. nov. The latter are described with Naiadites hibernicus sp. nov. from the Upper Namurian of Leinster, and Anthraconaia fugax sp. nov., a name for shells from the communis Zone of the Burnley Coalfield first described by Hind (1893) who referred them to Anthracomya wardi (Salter). Notes are added on Anthraconaia fabaformis (Kinahan) from Leinster and Tipperary. The work has led to the correlation of Ward's Seam of the Leinster Coalfield with the Upper Glengoole Coal of Tipperary. Near the top of the lenisulcata Zone, faunas of Carbonicola suggest the approximate correlation of the Coalbrook Band of Tipperary, the Glynneath (Ca) Band and the Norton Musselband of the East Pennines.
