Family Floricyclidae Moore and Jeffords, 1968

Acbastaucrinus affectatus Sisova, 1988 ( Fig. 3F–K ).—The material contains 107 columnals and short pluricolumnals. The thin heteromorphic stem is composed of circular, high and strongly convex columnals. The lumen is large, pentalobate bordered by weakly marked perilumen. The areola is flat and smooth, surrounded by extremely narrow crenularium composed of minute culmina. Poorly preserved specimens from some localities were previously ( Racki et al. 1989) classified as Glyphidocrinus . Occurs in the Pa. crepida to S. praesulcata zones: Kowala (samples Ko−B and C), Psie Górki (sample PG−B), Śluchowice, Miedzianka (sample Mi−B), Ostrówka, Besówka. The species was first described from late Famennian of Central Kasakhstan ( Sisova 1988).

Cyclocion sp. ( Fig. 3O–Q ).—The material contains 14 poorly preserved minute, circular columnals having a convex and smooth latus. The lumen is large, strongly pentastellate. Areola is wide and smooth bordered by very short culmina. The columnals were previously ( Racki et al. 1989) classified as Tomeocrinus . In general, the articular facet morphology seems to correspond to C. distinctus primus Sisova, 1988 from the late Famennian of Central Kasakhstan ( Sisova 1988), in spite of weakly marked (damaged?) crenularium. Occurs in the Pa. crepida to S. praesulcata zones: Kowala (samples Ko−B and C), Psie Górki (sample PG−B), Ostrówka.
