known from the Carnian, divided stratigraphically from the new species described from the Anisian. The other new, Anisian species of Encoiloceras, described below, has significantiy more depressed whorls and less coarse ornamentation than E. balatonicum. Distribution — The specimens were collected from the Bed 5 (Aszófő I.) and the scree nearby, belonging to the Balatonicus Subzone of the Balatonicus Zone (VÖRÖS 1987). Encoiloceras lajosi sp. n. (Plate I: 4, 5a-b, 6a-c, Plate II: la-b; Figure 4.) Holotype — Plate II: la-b; Figure 4 A (M.99.107) Paratypes — Plate I: 4, 5a-b, 6a-c; Figs. 4 B, C, D (M.99.108, M.99.114, M.99.115) Type locality — Aszófő, Farkó-kő (Balaton Highland, Hungary 7 ) Type strata — Grey, nodular limestone, Binodosus Subzone of Trinodosus Zone (sensu Vörös 1987). Derivation of name — Commemorating Lajos DOSZTÁLY, specialist on radiolarians, who was the heart and soul of our collecting works at the Balaton Highland until his unexpected death in 1999 at the age of 38. Diagnosis — Very evolute Encoiloceras with wide umbilical perforation; whorls are depressed, with subquadrate, slightly trapezoidal cross-section; flanks with ventrolateral and umbilical nodes of medium strength. Material — Four specimens: the holotype and three paratypes.

Description — The holotype is a medium-sized, incomplete internal cast with 1/4 whorl preserved body chamber. The coiling is very evolute; the whorls are in contact, but overlap only very slighdy. The umbilical perforation, as seen on the broken axial surface, is very wide. The whorl-section is depressed, slighdy trapezoidal, the ventrolateral shoulder is wider than the umbilical margin. The umbilical wall is steep; the
