Hymenolepis hamanni (Mrazek, 1891) (Fig. 5) Host: Neomys fodiens. - Localization: small intestine. - Intensity: 2 specimens. - Date of collection: Lenartov 10-12 Nov., 1981 (1 case). Note: H. hamanni parasites Neomys species. The examined specimens have scolices 0. 18-0.20 mm wide, diameter of rostellum is 65 jam, hooks 17-18 in number, 27yum long, at the basis 25 um, guard bifurcate. Hymenolepis montana Murai, 1984 (Figs 6-9) Host: Neomys fodiens

. - Localization: small intestine. - Intensity: 2-20 specimens. Date of collection: Hertnik 26-28 Aug., 1980 (1 case), Lenartov 10-12 Nov., 1981 (2 cases). Note. Length of the species described elsewhere (MURAI, 1984) is 14-18 mm, greatest width 0. 3 mm. Diameter of scolex 0. 30-0. 38 mm, length 0. 35 mm. Diameter of suckers 150-180 jam, that of rostellum 90-100 jam. Size of rostellar sac 150-270 jum. Number of hooks always 10, characterized by bifurcate guard, 37-40jam long, 35-37 jam at the basis. Testes arranged in triangle, cirrus sac 60-100 jam long and 20jum wide. Uterus saccular, with 20-24 ripe eggs in the old mature proglottids, not forming egg capsule. Eggs ovoid, 33-38 by 40-52 jam in size, oncosphere 20x35 urn in size, embryonal hooklets 9jum long. A common parasite of N. fodiens all over the Carpathians. YAMAGUTI (1959) erected a separate genus to accommodate the species with bifurcate guards: Triodontolepis Yamaguti, 1959. The species referred into this genus parasite shrews, rodents and bats. The description of the genus included the formation of egg capsule from the last proglottids. PROKOPIC* (1972) accepted the genus as valid and among others referred Hymenolepis bifurca and H. hamanni here. Neither of the authors made note of the significance of the fact that some of the species have consistently 10 hooks, whereas in others the number of hooks ranges from 17 to 50. The formation of the egg capsule is also not fully demonstrated for all species, therefore until such time when the genus becomes better known it is best to retain the generic name Hymenolepis. Hymenolepis intégra (Hamann, 1891) (Figs 10 — 11) Host: Neomys fodiens

. - Localization: small intestine. - Intensity: 10-73 specimens. Date of collection: Hertnik 26-28 Aug., 1980 (1 case), Lenartov 10-12 Nov., 1981 (3 cases). Note. The mature specimens of H. intégra are 10-14 mm long, with greatest width of 0.3 mm. Diameter of scolex 0.21-0.24 mm. Rostellum deeply retracted into scolex, HOjam in diameter with a crown of numerous (more than 60) minute hooks 11-13 jam in length. Diameter of suckers 100 jam. The 3 testes arranged in a triangle. Size of cirrus sac 75x15 jam, that of the finely spinulous cirrus 50x15 jam. Ovary and vitelline gland centrally situated in the proglottid. After the 170th proglottid the formation of egg capsule may be observed. Measurements of ovoid egg capsules 120 by 180 jam, each containing 40-50 eggs. Size of eggs 50 by 66 jam, that of .the oncosphere 18 by 27 jam, length of embryonal hooks 10 jum. Hymenolepis omissa Baer & Joyeux, 1934 (Figs 12-13) Host: Neomys fodiens. - Localization: small intestine. - Intensity: 10-65 specimens per host. - Date of collection: Lenartov 10-12 Nov., 1981 (4 cases). Note. Measurements of the mature specimens of H. omissa are as follows. Length of strobila 4-5 mm, greatest width 0. 2 mm. Diameter of scolex 0. 2-0. 24 its length 0. 3-0. 36 mm. The rostellum is situated deep in the scolex, its diameter is 20-30 jum, with a row of 24 hooks on it, length of hooks 5 jam. Testes arranged triangularly, the ovary and vitelline gland placed centrally. Size of cirrus sac 120 by'

25 jam, cirrus with strong spines, 50 by 25 jam in size. Formation of egg capsule beginning in the 55th segment, its size 7 5 by 170 jam with 9-12 eggs. Eggs measure 55 by 40 jam, oncospheres 37 by 25 jam, length of embryonal hooks 10 jam. Note. GENOV (1980) referred the last two species to the genus Coronacanthus Spa s sky, 1954. The morphology of the two species corresponds well with the description given by GENOV. I wish to point out one characteristics, however, the cirrus sac and cirrus of H.omissa is relatively large in comparison with that of H. intégra. Both species are common parasites of Neomys species. Hymenolepis furcata (Stieda, 1862) Host: Sorex araneus. - Localization: small intestine. - Intensity: one specimen. - Date of collection: Hertnik, 26-28 Aug., 1980 (1 case). - H. furcata is a well-known parasite of S. araneus in Slovakia.
