"Small, highly specialized, monocyclic crinoids from the middle Devonian Hlubocepy limestone of Bohemia [Czechoslovakia] are referred to the new genus, Holynocrinus, which is especially characterized by having three plates in the radial circlet. Two new species (H. moorei and H. spinifer) are described. Holynocrinus is assigned to a new family, the Holynocrinidae, belonging to the order Disparata Moore and Laudon. The Holynocrinidae, however, seem to have no close relations with any previously known crinoids."
