butional data in the literature have been summarized and a host list were given by PROKOPIC and GENOV (1974), then TENORA and ZEJDA (1974). New data were published by SHARPILO (1975) from the Soviet Union. Reviewing the above data, the species seems to infect, though rarely, also other rodents. However, its commonest host is C. glareolus. 2. Heligmosomoides glareoli Baylis, 1928 (Fig. 3A-F) For distribution in Hungary see Table 1 and map. - Localization: small intestine. Extensity 10.5%; intensity 1-28 specimens. Synlophe: Surface of body with 16 longitudinal cuticular crests (crête), withouth inner chitinized frames. Crests from just behinde vesicle and to bursa in males, to vulva in females. Two ventral crests strongly developed. Male: Body length 3.50-4. 70 mm, maximum width 0. 62-0. 68 mm. Esophagus length 0.45-0.50 mm. <Nerve ring 0.11-0.15 mm, excretory pore and filiform deirids 0. 25-0. 38 mm from anterior end. Bursa copulatrix symmetrical. Short dorsal ray branching into four. Short extensions branching out mear inner base of each externo-dorsal ray; in some specimens meeting each other thus forming a "bridge". Lateral rays equally developed and originating from common trunk. Ventral rays also from a common trunk. Latero-ventral rays the more developed. Prebursal papillae present. Well discernible genital cone. Thread-like spicules 1.00-1. 20 mm long and forked at tip, one of the branches shorter. Gubernaculum absent. Female: Body length 7.80-9.50 mm, maximum width 0.08-0.09 mm. Esophagus length 0. 59-0. 64 mm. Nerve ring 0. 19-0. 21 mm, excretory pore and filiform deirids 0. 300. 32 mm, from anterior end. Distance of.vulva 0.30-0. 32 mm, that uf anus 0.072-0.090 mm, from posterior end. Eggs 0.061-0.065 mm long by 0.032-0.040 mm wide. Tail with small terminal spike. According to tour present knowledge the species is a parasite C. glareolus of the plains and hilly regions. The most important distributional data were summarized by TENORA and ZEJDA (1974). A newre description of H. glareoli was made by MISHRA et al. (1976) . 3. Heligmosomoides polygyrus polygyrus (Dujardin, 1845) Distribution in Hungary: Őriszentpéter (Com. Vas): - Localization: small intestine. - Extensity 0.20%, intensity 5 specimens. One of the most common parasite of Apodemus spp. in Hungary. In one case it was found in C. glareolus. 4. Trichostrongylus retortaeformis (Zeder, 1800) Distribution in Hungary: Iharos (Com. Somogy). - Localization: small intestine.Extensity 0.20%, intensity 2 specimens. A common parasite of rabbit and hare in Hungary. It was found in one C. glareolus. YAMAGUTI (1961) reports in his book a finding of the species in C. glareolus on the Inner Hebrides. 5. Angiostrongylus (P. ) dujardini Drozdz et Doby, 1970 (Fig. 4A-E) For distribution in Hungary see Table 1 and map. - Localization: heart and lungs. Extensity 5-7%, intensity 1-8 specimens. Live worms transparent, brownish red intestine weD. discernible. Mouth triangular, surrounded by four papillae and two amphids. Male: Body length 8.50-12.0 mm, maximum width 0.18-0. 23 mm. Esophagus length 0.24-0.27 mm. Nerve ring 0.16-0.21 mm, excretory pore 0.35-0.44 mm, from anterior end. Trilobed bursa copulatrix symmetrical. Dorsal ray short, thick, terminating in two hemisphaerical appendages. Externo-dorsal rays slightly longer than dorsal one. Lateral rays stubby, originating from a common trunk, latter emitting first antero-lateral rays. Mediolateral rays longest of all lateral ones. Ventral rays also from a common trunk, branching
