2.- Riss-Würm, interglacial species, partly forest-forms. These indicate mild climate. Their shell-casts are calcareous sand or travertine mud (rarely loessy sand), and in many cases they are encrusted with fresh-water limestone. Cochlicopa lubricella Orcula doliolum Mastus bielzi Cochlodina laminata Laciniaria plicata Discus rotundatus Oxychilus inopinatus Phenacolimax annularis Limacidae indet. Helicodonta obvoluta Soosia diodonta Cepaea vindobonensis Helix pomatia 3.- Aquatic species. The cast of their shells is fresh-water limestone or lime mud in most cases. Their age probably is Riss-Würm (as by the former terrestrial species) or older. Valvata cristata Valvata piscinalis Valvata naticina Lithogtyphus naticoides Lymnaea stagnalis Radix peregra peregra Radix peregra ovata Planorbis planorbis Anisus vorticulus Gyraulus albus Gyraulus laevis Several species (not listed here) may belong both to the Würm loess-fauna and to the Riss-Würm material. Two water species are fluvial, that means that the fresh-water springs, which had deposited the travertine, probably were discharged into a larger stream. (The specimens of the third fluvial species - Theodoxus danubialis - probably were drifted into the deposit secondarily.) Comparing the snail fauna with the vertebrates, we can state that both material showed the climatical and stratigraphical differences between the "fine-grained" and "coarse-grained" layers, and that due to the depositional processes the faunas of the layers are somewhat mixed.
