ANNALES HISTORICO-NATURALES MUSEI NATIONALIS HUNGARICI Tomus 52. PARS ZOOLOGICA 1960. Data to the Mollusk Fauna of Hungary By P. AGÓCSY and T. Pócs, Budapest The Mollusk Collection of the Hungarian Natural History Museum was wholly annihilated in 1956. The new collection, brought together since then, is based partly on purchases partly on collectings. In the course of the following two years, we have visited several home areas, and of the results of our collectings we submit hereby those data which originate from hitherto unknown localities. The destroyed mollusk collection was tenfold the size of the present one. However, its material was a rich representation of the mollusk faunas of rather the Carpathians and the Croatian seaside. This was understandable, since Croatia, Transylvania and the High Tatra are the collecting localities of several valuable and rare snails even in respect to the whole mollusk fauna of the world. The present collection presents a faunistical picture of preponderantly the present areas of Hungary. Accordingly, we already dispose of data, concerning the situation within our borders, of forty more localities than was the case with the old collection. Following these preliminary remarks, we give a short characterization of the more significant collecting areas of the past two years ; the serial numbers of the localities of the list below will also serve as reference numerals in the systematic enumeration. 1. — Mts. Zemplén (Mts. Sátor) : Kőkapu, Telkibánya, Füzéri vár. 2. — Mts. Bakony : Bakonybél, Magyarpolány. 3. — The foot of the Alps : Szakonyfalu, Vasvár, Felsoszölnök. 4. — The hilly area of Com. Zala : Gógánfa, Zalaszentgrót, Tormafölde, Bak. 5. — The volcanic basalt cones NW of Lake Balaton : Badacsony, Somlóhegy. 6. — Mts. Bükk : the Szalajka valley, Jávorkút, Kácsfürdő, Leányvölgy, Garadnavölgy, Nagyhárs, Nagydél. 7. — The Torna Karst : Jósvafö, Szögliget, the vicinity of Bódvarákó. 8. — Mts. Pilis Dunazug : the Rám gorge, Kétbükkfanyereg, Vaskapu, Simonhalála, Feketeko. 9. The Northern parts of the Great Plains : Baktalórántháza, Petneháza, Csaroda (the Bereg Plains). 10. — Csepel Island : Szigetújfalu. 11. — The peaty areas between the Danube and the Tisza : Ocsa. 12. Szeged. Before the systematic enumeration, let us now shortly discuss the more interesting collecting localities. In the Mts. Sátor, we have found, in all localities mentioned above, the slug species Bielzia coeruleans, rare in Hungary, and of a Carpathian-Sudetic range. Two of the collected animals were blackish-indigo blue, seven were sky blue, three violet-blue, three turquoise green. It is w r orthy of note that eight of the eleven specimens found in the Ósva valley near Telkibánya were albinos, wholly white or of a creamy color. The soils of the Mts. Sátor evolved on a basic rock poor in limestone, they are generally of an acidic reaction, containing but a meagre amount of CaCO ;i . Their snail fauna is therefore comparatively poor loo :
