Remarks: Three female specimens studied are close to S. lancea (Westrumb, 1821) and to S. lanceoides (Petrochenko, 1949) Golvan, 1956 both from passeriform and charadriiform birds but they have 34-36 longitudinal rows of hooks compared to Sphaerirostris lancea with 30-32 rows (PETROCHENKO 1958, BELOPOLSKAYA 1983) and S. lanceoides with 36-40 rows (KHOKHLOVA 1971, BELOPOLSKAYA 1983). Another difference of our specimens in the blade length - it is up to 0.450 and is closer to S. lancea 0.044 - than to S. lanceoides - 0.049. The measurements of the specimens studied, compared with data of the literature, are shown in Table 2. For lack of material (missing males) we were not able to differentiate it quite definitely as S. lancea. S. lancea is a common parasite of charadriiform and passeriform birds and an acanthocephalan widespread in Europe, China, Taiwan, Egypt and the U.S.A. (SCHMIDT 1969, KHOKHLOVA 1986). MURAI et al. (1983) reported 5. lancea from Vanellus vanellus and Philomachuspugnax in Hungary for the first time. Family POLYMORPHIDAE Filicollis anatis (Schrank, 1788) Specimens studied: írom Anas platyrhynchos: No. 1564, 2 females, Hortobágy, July 1968; No. 2092, 1 male and 1 female, Hortobágy, November 1970; No. 8150, 2 males, Péteri-tó, Kiskunság National Park, March 1979; No. 11331, 1 female, Ti-hany, March 1984; from Bucephala clangula: No. 9353, 1 male, Kisbalaton, January 1981; from Fulica atra: No. 739, 2 females, Hortobágy, September 1965; No. 3240, 1 male and 1 female, Agárd, September 1971; No. 3256, 1 male, Agárd, Sep-tember 1971; No. 3267, 4 females, Agárd, September 1971; No. 3268, 3 fema-les, Agárd, September 1971; No. 7297, 1 female, Hortobágy, September 1976.

Proboscis oviform, wider in its posterior half; 0.344-0.356 long and with maximum width 0.250-0.306. Armature consisting of 18-20 longitudinal rows of 9-11 hooks each. First 7-8 hooks uniform, with well-developed blades with length of the first 0.030-0.0325 and of 2nd8th 0.0375-0.040; blade length of last hooks 0.030-0.0325; only anterior hook roots clearly seen, 0.02750.0375 long; other roots rudimentary (for further hook measurements see Table 4). Neck conical, 0.620 long and 0.320 wide at base. Proboscis receptacle double-walled, attached at proboscis base; 0.92-1.20 long, with maximum width 0.14.
