Abstract
In field research into Dugi otok outside the confines of Tela{}ica Nature Park, and two northern islets (Mali Lagan, Veli Lagan) we found 35 species of terrestrial snails with shells. Of these, 33 species had been recorded in the literature with reference to Dugi otok, including the surrounding southern islets that form part of Tela{}ica Nature Park. Cepaea vindobonensis and Hygromia cinctella are species that have been newly found. Our investigations did not reveal 10 species that are cited in the literature. We considered that two taxa (Delima blanda conspurcata, Cepaea nemoralis) do not live on the island and the islets stated, while the remaining eight taxa (Vallonia costata, Granopupa granum, Truncatellina claustralis, Agathylla lamellosa, Delima edmibrani, Testacella scutulum, Cochlicella acuta, Chilostoma setosa) are held to be certain denizens of Dugi otok, which we did not find because our investigations were not systematic enough or because they do not live outside the area in which they were recorded (Tela{}ica Nature Park). Among the species that attract particular attention are: Delima edmibrani, which is narrowly endemic to Dugi otok; Agathylla lamellosa, of which this is the northernmost finding site; Chondrina spelta ventilatoris, because it is the westernmost finding site; and Testacella scutulum and Paralaoma servilis, because they are found so seldom in Croatian malacofauna. Dugi otok, with the surrounding islets and rocks mentioned, has a total of 43 species, which constitutes, in comparison with other islands of the eastern Adriatic, a relatively rich terrestrial malacofauna.

Croat., Vol. 14, No. 1., 1–28, 2005, Zagreb. Terenskim istra`ivanjima Dugog otoka izvan granica PP »Tela{}ica« i dva sjevernije polo`ena oto~i}a (Mali i Veli Lagan) na{li smo 35 vrsta kopnenih pu`eva s ku}icom. Od toga su 33 vrste bile u literaturi zabilje`ene za Dugi otok uklju~uju}i i okolne ju`ne oto~i}e koji ulaze u sastav PP »Tela{}ica«. Novona|ene su Cepaea vindobonensis i Hygromia cinctella. Na{im istra`ivanjima nismo na{li 10 vrsta zabilje`enih u literaturi. Za dvije svojte (Delima blanda conspurcata, Cepaea nemoralis) smatramo da ne obitavaju na otoku i navedenim oto~i}ima, a preostalih 8 (Vallonia costata, Granopupa granum, Truncatellina claustralis, Agathylla lamellosa, Delima edmibrani, Testacella scutulum, Cochlicella acuta, Chilostoma setosa) smatramo sigurnim stanovnicima Dugog otoka koje ili zbog nedovoljne sustavnosti istra`ivanja ili zbog toga {to svojte ne obitavaju podru~ja izvan PP »Tela{}ica« Croatian Natural History Museum, Demetrova 1, Zagreb, Croatia 2 [tamol, V. & Klete~ki, E.: Terrestrial snails (Mollusca: Gastropoda terrestria) of Dugi otok (Croatia) nismo na{li. Me|u vrstama treba istaknuti Delima edmibrani kao stenoendem Dugog otoka, Agathylla lamellosa zbog najsjevernijeg nalazi{ta, Chondrina spelta ventilatoris zbog najzapadnijeg nalazi{ta, te Testacella scutulum i Paralaoma servilis zbog rijetke pojavnosti u hrvatskoj malakofauni. Dugi otok s navedenim okolnim oto~i}ima i hridima broji ukupno 43 vrste {to predstavlja, u usporedbi s drugim isto~nojadranskim otocima, relativno bogatu kopnenu malakofaunu.
