of tectonic origin along a structural line on the northern side of the Schafbergspitz. From STOLICZKA's (1861) notices on the frequency of the species, it is inferable that a more abundant collection has been available for him also from the typical Schafberg Hierlatz Limestone than the material, which is found in the indicated depositories. Similar is the situation with the Gratzalpe "bei Aussee" locality 7 ; only a few specimens are in the GBa "originals collection" but the remarks in the descriptions indicate more syntypes that are not found. The reversed comma is used in this locality name because the Gratzalpe can not be found in the vicinity 7 of Aussee (today Bad Aussee) as it is written in STOLICZKA (1861), but in the north-eastern part of the Hagengebirge, south-west from Golling, south from Salzburg (Austria; pers. infomiation from G. MANDL, Geologische Bundesanstalt). This locality appears in the literature also as Kratzalpe, but recent maps indicate this area with the name Kratzalm (Figure 1). The labels of the available syntypes indicate that they come from Upper Sinemurian (Obtusum Zone) strata. The revision concerns also the materials that have been published by the writer of these lines (SZABÓ 1979, 1980, 1981, 1982,' 1983, 1984, 1995) from several localities of Sinemurian and/or Pliensbachian from the Bakony Mts (Hungary) without a possibility to compare them to the formerly published collections. Most of these specimens are deposited in the Hungarian Geological Museum, being part of the Hungarian Geological Institute. A few specimens from recent collecting activity are housed in the Hungarian Natural History Museum, Budapest. More about the Bakony Mts localities (see Figure 1): — 1 ST group: Ló kút, Kericser. Upper Sinemurian to Upper Pliensbachian, more or less typical Hierlatz Limestone of stratified development; Lókút, Fenyveskút. Upper Pliensbachian, atypical Hierlatz Limestone, being rich in micritic cement, deposited on slopes and in fissures of sea bottom; Eplény, manganese ore mine (~4 km east from the previous localities): atypical, Upper Pliensbachian Hierlatz Limestone, similar to that of the Fenyveskút occurrence, from a submarine dyke of Upper Triassic Dachstein Limestone in a subsurface mine; Hárskút, Kö\öskúti-árok (several km west from Lókút): lowermost Pliensbachian (Ibex Zone) limestone of submarine elevation origin, but lithologically different from the Hierlatz Limestone (type locality for Discohelix acarinata, found also in Hierlatz Limestone); — 2 nd group: Úrkút, Csárdahegy: massive, not bedded Lower? Sinemurian Hierlatz Limestone with generations of younger submarine dykes, exposed in abandoned manganese ore pits; the Szentgál artificial exposures, opened to study the Tu^köves-hegy Jurassic strata; uppermost Sinemurian (Raricostatum Zone) stratified Hierlatz Limestone; — 3 rd group: Sümeg, Mogyorósdomb nature and archaeological conservation area: Upper(?) Sinemurian Hierlatz Limestone from neptunian dykes in lowermost Jurassic Kardosrét Limestone contained gastropod faunulae.
