the same of the Scaphopodae and cca 20 items of the Cephalopodae to be found in the museum. A considerable part of the total sum of the items is formed by the snails, mainly the terrestrial and the fresh-water ones. We have about four thousand items of freshwater and marine shells. The number of the items of the snails (Gastropoda) in the inventory book is above 16 000. The inventory book cantains only items with well determined exact provenance, indicating also the number of pieces. We also make notice of pieces removed for exchange or examination. The uninveutorized, but indentified material reaches 10—12 000 items, and there are about 2—3000 items of snails to be elaborated. The snail shells were groupped in three groups in 1982 as well:the terrestrial and freshwater shells in Hungary, the world material and the marine snails. Since that time the Hungarian collection has been groupped, to gain space, in the word material, thus the order of the terrestrial and freshwater snails is unbroken from the Neritidae till he Helicidae, disregarding geographical distribution. Not even the Hungarian species can be found in the collection in their totality: 5 Hungarian species are missing from the museum collection. At least some items of the European, mainly Central European species would basically be necessary, anyhow, we can exhibit satisfactory collection only from the Balcanic countries, with the help of private collectors. There are only a few families in the collection where the number of the species is adequate as comparative material for indentification. Most of the families are represented by but a low number of species. Some of the more important groups: Hydrobiidae (cca 130 species), Clausiliidae (cca 350 species), Endodontodae (cca 50 species), Zonitidae (cca 90 species). The Balkan collections (Jugoslavia, Bulgaria, Greece) arc the most important ones from Europe. We have relatively many Gastropoda species from overseas regions like Cuba, Australis, New-Zealand. A larger part of the collections from Ghana, Kongo, Tansania and India cannot be identified fox lack of technical literature. TO
