Six new crinoid species are described from the Lower Mississippian (Osagean, late Tournaisian) Edwardsville Formation of Monroe County, Indiana. New species include Cyathocrinites cf. glenni, Barycrinus stenobrachium, Atelestocrinus indianensis, Nipterocrinus monroensis, Macrocrinus strotobasilaris and Uperocrinus apheles. The specimen designated as holotype of C. glenni is from Davidson County, Tennessee. Paleogeographic and morphological notes on other crinoids are given including Catillocrinus, Saccosomopsis poterium, Histocrinus coreyi, Holcocrinus nodobrachiatus, Camptocrinus plenicirrus, and numerous Crinoidea incertae sedis.
