Abstract (in english)
   Based on material from the Barremian/Aptian of Albania, the nerineacean Adaptyxis n.gen. is described. It possesses high turriculate shells with concave whorls of moderate height. Because of the hollow columella it is assigned to the Umboniidae Lyssenko & Aliev. The columella is hollow. Of the internal plaits, the adaptical columellar plait is very small. The other columellar plait, the palatal plait and the pariental plait are strong. Because of the internal morphology, Adaptyxis is considered as transitional between the genus Affiniptyxis Lysenko & Aliev and Plesioplocus Pchelintsev. Synchronously, Neoptyxis Pchelintsev evolved from Affiniptyxis. Both genera are part of the Simploptyxidae Hakobjan. An origin of the Umboniidae and the Ptygmatidae from a Melanioptyxis- like group in the Jurassic is considered.
   It is not clear whether the Nerineidae originated from the same group as the other nerineacean families or from the Mathildoid family Anoptychoidae, as was postulated by Bandel (1995)
