Shape — High, cap-shaped form with apex, curving backwards behind line of peristome. In collabral crosssection, shell flattened along selenizone, but convex in other parts. Selenizone slighdy elevated, peristomal slit extending to about one-third of shell height. Peristome slighdy ovate in anterior-posterior direction. Sculpture — Shell ornamented with spiral and collabral threads of nearly equal strength, resulting in network sculpture. In interspaces of spiral riblets, secondary riblets develop in later growth stage. Lunulae of selenizone similarly strong as secondary spiral elements. Density of lunulae roughly three times higher than that of collabral ribs. Fine growth-lines also observable. R e m a r k s — The Bakony specimens resemble Emarginula (E.) lepsiusi GF.MMF.T-T.ARO, 1879, but this latter has fewer ribs, different size and convex shell along the anal slit. DE TONI'S (1912) figures show weaker collabral riblets than the spiral ones, while both elements are of equal strength in the Bakony specimens. However, the latter shells are rather strongly re-crystallised and this effect might have modified also the details of the shell morphology. Distribution — Vedana ( Alps, Italy), Middle Liassic; Lókút, Kericser (Bakony Mts), Ibex to Davoei Zones; Gorgo a Cerbara (Central Apennines), Upper Pliensbachian; Bileçik (Western Pontids, Turkey), Upper Sinemurian to Early Pliensbachian.

Lectotype — GBa 2008/69/23 (selected here). Material — Lots of specimens, 51 cleaned and many on rock pieces of other species (GBa), four ones in the HGM. Measurements II HL HP lectotype 13.3 10.7 6.8 Shape — LOAV turbiniform shell, with blunt apex, strongly convex whorls and base. Shell bending up along moderately impressed suture. Base convex and has no umbilicus. Last peristome continuous, prosocline and subcircular; aperture orbicular. Columellar lip strong and having rather wide outer face with swelling at foot of columella. Shallow, wide, backward sinus of basal lip starts from abapical end of swelling and almost reaching peripheral part of outer lip. On wide outer face of peristome part with sinus, shallow furrow visible. Sculpture — Fine growth lines and obscure spiral striae give ornament both on whorls and base. Growth lines prosocline on whorls and feebly parasigmoidal on base. Remarks — Some fragmentary specimens suggest presence of a narrow umbilicus that becomes closed in the last growth stage. TATL's (1876) Turbo latilabrus STOLICZKA differs from the others in its feebly cyrtoconoidal outline. Practically, there are no differences between the lectotype and the specimens from the Bakony Mts finds that were firstly identified as two different species by SZABÓ (1981, see synonym list above).
