Material: Only one cup (NS 6/ 464). Occurrence: The synonymized material from Poland as well as our specimen are Early Tithonian in age. Suborder CYR TOCRININA SIEVERTS-DORECK, 1952 (emend. NICOSIA, 1992) Superfamily EUGENIACRINITOIDEA ZITTEL, 1879 (emend. NICOSIA 1992) Family EUGENIACRINITIDAE ROEMER, 1855 Genus Lonchocrinus JAEKEL, 1907 Type species: Eugeniacrinus dumortieri LORIOL, 1882 Diagnosis: Presumed IBR2 axillary characterized by long medial spine. Proximal articulation synostosial, the two distal ones muscular. Remarks: This genus, similarly to Gymnocrinus, was based only on axillary brachials that are considered to be, by definition, first AxAx. Some cups were assigned to this genus by Arendt (1974), Pisera and Dzik (1979) and Gluchowski (1987). Provisionally this view is accepted here, although it is necessary to verify the morphological and functional affinities between the cups and these axillaries. Several species of the genus are known from the Bajocian to Neocomian deposits of Europe. Lonchocrinus staszici PISERA et DZIK, 1979 Pl.

Description: Small and gently oblique cup, pentagonal in outline. Low and stout RR with laterally sloping radial facets. Sutures between RR clearly visible. Radial facets wide, subdivided into two articular surfaces: a subvertical aboral and an outward sloping adorai one. Aboral articular surface crescent-shaped, entirely occupied by a wide and deep ligament fossa with a very small ligament pit. Adorai surface characterized by two muscular fossae separated by a radial groove. Aboral and adorai surfaces separated by a transverse fulcral ridge. Interradial projections low, triangular in cross-section with flat inner side. Ventral cavity conical, deep and wide with clearly visible radial grooves. Dorsal side wide, circular in outline with granulated margins, entirely occupied by a wide, circular and deep cavity with clearly visible sutures. AxAx: Small IBrBr2 bearing a long, spine-shaped dorsal process. Brachial high, sloping outwards, bearing two relatively small, laterally expanded shieldshaped expansions. Dorsal side convex and smooth. Proximal side entirely occupied by lower articulation of synostosis-type. Articulation smooth and almost flat having a central axial canal. Two upper articulations of muscular-type located in
