A low diversity fauna of microscopic crinoids from the Kinderhookian (Mississippian) McCraney Limestone at Seehorn Hollow, western Illinois, is described and illustrated by stereomicrographs. The crinoids include first record of the camerate crinoid genus Hexacrinites (H. mississippiensis n. sp.) above the Devonian. The other three taxa are all inadunates and include the monocyclic microcrinoid Allagecrinus mccraneyensis n. sp., which has up to 14 arms, and two dicyclic poteriocrinoids, Hypselocrinus maccabei (Miller and Gurley, 1894) and an indeterminate genus of the Scytalocrinidae.
