Family Stenocrinidae Dubatolova, 1971

Stenocrinus altus Sisova, 1988 ( Fig. 2I, J ).—The material contains 27 rather high columnals with flattened articular facet perforated by small pentagonal to pentalobate lumen. The areola is narrow bordered by wide crenularium composed of long, dichotomous culmina. The latus is weakly convex with minute tubercles and small cirrus scars on nodals. Poorly preserved specimens from some localities were previously ( Głuchowski 1981a, b) classified as S. degratus Dubatolova, 1975 . Occurs in the Pa. triangularis to S. praesulcata zones: Kowala (samples Ko−A, B, and C), Psie Górki (sample PG−B), Kadzielnia, Ostrówka and in the Pa. crepida to Pa. marginifera zones of the Moravia, Czech Republic (Mokrá quarry). The species was initially described from late Famennian of Central Kasakhstan ( Sisova 1988).

Calleocrinus kielcensis Głuchowski, 1993 ( Fig. 2K–N ).— The material contains 192 columnals and pluricolumnals. The heteromorphic stem is composed of low columnals with straight or weakly convex latus. The articular facet is flat and covered with numerous dichotomous culmina. The lumen is very small, stellate to circular. Poorly preserved specimens from some localities were previously ( Głuchowski 1981a, b) classified as Salairocrinus humilis ( Dubatolova, 1971) . Occurs in the Frasnian of Southern Poland and probably Dinant Basin, Belgium ( Głuchowski 1993) and also in the Famennian Pa. triangularis to Pa. marginifera zones: Psie Górki (samples PG−A and B), Kowala (samples Ko−A and B), Kostomłoty, Kadzielnia.
