S. Szigethy Anna: A Természettudományi Múzeum Mollusca Gyűjteménye

lectors are willing to enter into the more tiresome alcoholic collection. The other class of the molluscs is the shells (Bivalvia). It contains 2100 identified and inventorized and cca 2000 ungroupped, unidentified items. The freshwater and the marine sehells ara arranged in continuous order in the collection, though the repeated groupping, the arrangement of the new items made some disorder. The reestablishment of the order and the reidentification of the shells would be needed. We cannot speak of alcoholized shell collection, as there are only 100 items of freshwater and marine shell-bodies preserved. There are so few Cephalopodae, Polyplacophorae, Scaphopodae in the collection both in number of species and items, that no scientific work can be carried out on them. The mollusc collection, regarding the short time of its existence, owns a respectively large number of types. Type catalogue, published by László Pintér in 1982 gives the list of all the species. Here I would like to mention, that the 99 species contain 28 holotypes, 92 paratypes and 1—1 syn- and paraletotypes. The Hungarian malacologues added not only to the quantity of the collection, but also helped in the identification of some groups. Several foreign authors have worked on the material, too. A. Wiktor revised and identified the whole of the slug material of the collection. H. Nordsiek helped in the identification of the Balkan Clausiliidae, while H. Schutt helped in that of the Balkan Hydrobiidae families. A new collection was set up with the help of Hungarian and foreign museums and private collectors to retrieve the immense molluscan material of the Natural History Museum that had perished in a conflagration in 1956. The enrichment, abrupt till the early 6oies, has rather decreased lately. The present stock consists of 37—40 000 items, most of them are terrestrial and freshwater snails. Besides there are marine snails, marine and terrestrial shells, and also some items of Polyplacophorae, Scapophodae and Cephalopodae. The alcoholic collection also
