A new specimen of the early Arenig inadunate crinoid Ramseyocrinus shows unequivocally that the genus had a cup composed of four basal and five radial plates, the latter supporting five arms. There are no anal plates in the dorsal cup. The separate familial status of the genus is confirmed and emended diagnoses of the family, and genus, and a revised description of the species R. cambriensis are given.
