umbilical edge is blunt. The venter is gendy arched, with a slight depression at the middle. The lateral flanks are ornamented with nodes of medium strength. The phragmocone has a row of weaker nodes at the umbilical margin and a double row of nodes near the ventrolateral shoulder; the double nodes coalesce toward the end of the phragmocone. On the body chamber the umbilical and ventrolateral nodes are connected by strong, blunt radial ribs; the ventrolateral nodes transform into bullae. A half whorl of the phragmocone bears 12 ribs/nodes. Suture lines are simple, having shallow lateral lobes and very low, arched ventral saddle, without ventral lobe. The internal lobe (seen on paratype M.99.108) is narrow and deep; annular lobe cannot be seen. Remarks — E. lajosi differs from E. superbum (MOJSISOVICS, 1873), the type species of the genus, by its more evolute and depressed whorls, more trapezoidal whorl-section and its ornamentation (nodes and ventrolateral bullae instead of coarse ribs). E. superbum is known from the Carnian, divided stratigraphically from the new species described from the Anisian. E. balatonicum has significandy less depressed whorls, more arched venter and coarser ornamentation than E. lajosi. Distribution — The holotype was collected from Bed 91 (Aszófő I.) ranged into the Binodosus Subzone of the Trinodosus Zone by VÖRÖS (1987). The paratypes came from Beds 80 and 82 of Aszófő I. (Zoldianus Subzone of the Balatonicus Zone) and Bed 5 of Aszófő II. (Balatonicus Subzone of the Balatonicus Zone), respectively. E. lajosi ranges through the Balatonicus Zone up to the lowermost part of the Trinodosus Zone. Genus Mojsvaroceras HYATT, 1883 Mojsvaroceras ? cf. binodosum (HAUER, 1887) (Plate II: 2a-b, 3; Figure 5) 1887 lemnocheilus binodosus n. sp. — H AUER, p. 18, pl.

Material — Two specimens; one incomplete phragmocone (M.99.116) and one 1/4 whorl of a body chamber (M.99.117). Measurements: D WH WW U UP 34.5 19 (55.1) 20 (58.0) 11.8 (34.2) — Figure 5 — Cross-sections and suture line of Mojsvaroceras ? cf. binodosum (HAUER, 1887). — A: cross-section of the specimen M.99.116, Aszófő I, Bed 79, Balatonicus Zone (Zoldianus Subzone), B: cross-section of the specimen M.99.117, Aszófő I, Bed 18, Balatonicus Zone (Balatonicus Subzone), C: suture line of the specimen M.99.116. at WH=11.5 mm, Aszófő I, Bed 79, Balatonicus Zone (Zoldianus Subzone). Description — The specimens are small-sized for the genus. The coiling is moderately involute (convolute). The whorls are stout, rather depressed; the cross-section is subquadratic, trapezoidal, narrowing ventrally. The umbilical wall is steep, gently arched; the umbilical edge is well-defined. The flanks are flat and pass gradually into the rounded venter. The flanks are ornamented with two rows of nodes; the ventrolateral nodes are strong, the umbilical nodes are very illdeveloped. The suture lines (Figure 4C) are rather simple, with wide and shallow lateral and ventral lobes and pronounced ventrolateral saddles. Remarks — The Aszófő specimens seem to be very similar to M. binodosum, but their poor preservation does not allow to go into a more detailed discussion of the species. Hauer (I.e.) and some later authors ranged M. binodosum into the genus Temnocheilus; while DI EN ER (1915, p. 334) placed it into Mojsvaroceras. Considering the general features of the species binodosum, it seems to stand closer to Enoploceras than to Mojsvaroceras. However, up to now, Enoploceras is known only from the Upper Triassic, therefore in the present paper binodosum is attributed to Mojsvaroceras with query. Distribution — M. binodosus was described from Bosnia and Montenegro from the upper part of the Anisian ("Lower Muschelkalk"). Our specimens were collected from Bed 18 (Balatonicus Subzone of the Balatonicus Zone) and Bed 79 of Aszófő I. (Zoldianus Subzone of the Balatonicus Zone), respectively.
