whorl advancing anteriorad on right side of body, but not extending beyond anterior margin of ventral sucker. Eggs traceable to genital pore opening on left side of body, at height of ventral sucker; 0.017—0.025x0.007—0.010 mm. Vitellaria constituting a uniform region between pharnyx and ventral sucker, at height of caecal bifurcation, and composed of numerous minute follicles. Cirrus pouch located on left side of body, immediately near ventral sucker. My material comprises 81 specimens from the following hosts and localities : Rhinolophus hipposideros, 1 çf, Leány Cave, Pilis, 17 Febr., 1966, 1 spec. Myotis myotis, 1 çf, Legény Cave, Pilis, 17 Febr., 1966, 4 and 1 spec. rep. Myotis oxygnathus, 1 9> Leány Cave, Pilis, 17 Febr., 1966, 1 spec. Myotis daubentoni, 1, Abaliget Cave, 19 Dec, 1957, 6 spec. Myotis dasycneme, 5, Abaliget Cave, 19 Dec, 1957, 5 — 7—15 — 18 — 7 spec resp. Miniopterus schreibersi, 1 çf, István Cave, Lillafüred, 27 Febr., 1966, 16 spec. Subfamilia: Gyrabascmae MACY, 1935 Genus: Ophiosacculus MACY, 1935 Ophiosacculus mehelyi (MÖDLINGER, 1930) (Fig. 10) Syn.: Distomum mehelyi MÖDLINGER, 1930; Prosotocus mehelyi SKARBILOVICH, 1948. Hosts: Eptesicus serotinus, Plecotus auritus. Distribution: Hungary, Czechoslovakia. A small-sized, ellipsoid Trematode. Length of body 0.750—0.825 mm, width of body 0.400—0.550 mm. Cuticle smooth. Oral sucker extremely well developed, 0.140-0.165 X 0.133-0.172 mm, subterminal. Pharynx small, 0.020-0.035 x 0.0320.050 mm. Oesophagus, contrarily to earlier authors, well discernible, of medium length. Caeca very short, not reaching testes. Ventral sucker round, considerably smaller than oral sucker, 0.100—0.110x0.100—0.120 mm. Testes rounded or oval, situated para-postacetabularly, symmetrically with one another; left testis 0.133— 0.150x0.100-0.150 mm, right testis 0.125-0.150x0.082-0.130 mm. Oval ovarium lying between ventral sucker and left testis, 0.085—0.132x0.095—0.100 mm. Eggfilled whorls of uterus occupying posterior part of body. Eggs brownish, 0.020— 0.025 X 0.010—0.012 mm. Vitellaria in two groups in anterior part of body, consisting of small follicles, originating at posterior part of oral sucker and extending caudad to ventral sucker. Ducts traceable to behind ventral sucker, into median line of body. Strongly developed cirrus pouch, describing a double curve, extremely characteristical ; originating in front of ventral sucker and extending along its left side, it curves medially behind it. Genital pore situated also here. Our collection comprises 27 specimens from the following three hosts: Eptesicus serotinus, 1, Villány, 25 May, 1960, 21 spec. * Rhinolophus ferrumequinum, 1, Abaliget Cave, 19 Dec, 1957, 2 spec. * Miniopterus schreibersi, 1, Ördöglyuk Cave, Pilisszentkereszt, 15 Jan., 1958, 4 spec The two bat species marked by * are hosts new for the parasite. Summary The paper submits systematico-faunistical survey of the Trematode material, belonging to 15 species, found in bats deriving from 22 localities in Hungary. The following Trematode species have been shown:
