seen in each row (others on not everted part). Hooks seen with measurements as follows (blade x root; from anterior to posterior hooks): 0.0625-0.0638 x 0.0675; 0.0575-0.0638 x 0.0625-0.0650; 0.0550-0.0625 x 0.0575; 0.0550 x 0.030. Neck elongate, conical, 0.450 long and with maximum width 0.375. Proboscis receptacle and lemnisci not studied. Testes elongate, oval; situated one behind other; measure 1.0-1.14 x 0.60-0.75. Cement glands 4 in number, tubular; two of them slightly larger (3.75 x 0.16) than other ones (3.00 x 0.16). Ducts of cement glands and genital bursa deformed. Female: Trunk elongate, without constriction, 7.05 long and with maximum width 1.95 in its posterior part. Anterior part (with length 1.80) of trunk covered with spines; spines situated in about 36-40 longitudinal rows of 19-20 hooks each. Proboscis almost oval; anterior part not evert-ed; 0.325 long, with maximum width 0.238 and width at base 0.175. Ar-mature consisting of 14 longitudinal rows; only 5 not wellpreserved hooks seen in each row (others on not everted part). Hooks seen with measure-ments as follows (blade x root; from anterior to posterior hooks): 0.0600 x 0.0675; 0.0625-0.065 x 0.0625; 0.0575; 0.05500.0575; 0.575. Neck elon-gate, almost cylindrical, 0.070 (part of it invaginated in trunk) and 0.188 wide. Proboscis receptacle double-walled, attached at proboscis base; 1.35 long, with maximum width 0.210 at distal end and width 0.163 at proboscis base. Lemnisci not studied. Trunk full of eggs. Eggs elliptical, elongate, 0.093-0.100 long and 0.018-0.020 wide; with polar swellings of middle shell. Remarks: The present material fully corresponds to P. phippsi, a species originally described from the same host and after that reported from different aquatic birds. There are, however, several differences: the dimensions of the third-fourth hook in our material is smaller (up to 0.065) than these in the descriptions of KOSTYLEW (1922, cited after PETROCHENKO 1958) and KHOKHLOVA (1966) - 0.068-0.071; the length of the cement glands of the Hungarian specimens is greater (3.00-3.75) in comparison with the cited descriptions (2.1-2.43). Unfortunately, the bad condition of the specimens does not permit more adequate comparisons. Southwellina htspida (Van Cleave, 1925) Witenberg, 1932 Specimens studied: No. 12334, 2 males (1,7) and 8 females (2, 3, 4, 5, 6, 8, 9, 10) from Egretta alba, Kiskunság, Solt, April 1990. Description (Tables 8, 9, Fig. 7): Male: Total length 8.43-10.00. Trunk fusiform, with characteristic con-striction in its anterior part; 5.796.06 long and with maximum width 1.38-1.41 about constricted place; posterior trunk part narrowed, 0.060-0.084. Anterior part of trunk with two zones of spines; first zone (with length 0.025-0.030) separated from neck by narrow unarmed collar-like structure; length of spines 0.0225-0.0275. In second zone (with length 0.50-0.78) spines situated in 72-92 longitudinal rows of 8-10 hooks each; spines triangular, 0.01750.0375 long. Unarmed zone with length 0.137-0.230 between two armed zones. Neck conical, 0.350 long and 0.480 wide. Proboscis cylindrical, widest in posterior part; 0.90-0.91 long, with maximum width 0.2630.338 in posterior part and width 0.188-0.225 in ante-rior part. Armature consisting of 19-20 longitudinal rows of 16-17 hooks each. First 8-9 hooks with well-developed blades: 1st 0.050-0.0525 long, 2nd-9th 0.060-0.070 (one of specimens with considerably longer hooks); root gradually longer, directed backward, 0.0375-0.0650 long; usually 8th-9th hooks with most massive root. Following lOth-llth hooks with shorter blades: 0.0475-0.0525 and 0.055-0.0575; 12th-17th hooks longer - 0.0575-0.0625, with shorter and narrower roots (0.0275-0.0375, only once 0.0425) directed forward (for more detailed data on hook
