The occurrence, location and sex ratio of Corynosoma strumosum (Acanthoceophala: Polymorphidae) from 26 juvenile grey seals, Halichoerus grypus, by-caught from around the Inishkea Islands, Co. Mayo, from March to June 1997 were recorded. The location of C. strumosum within the seal did not vary, with all worms being found in the small intestine. The prevalence of infection was 100%, with no other acanthocephalan species being recorded. The mean abundance was 416 (range 80-846) C. strumosum per seal. There was no significant change in abundance by month. The sex ratio of mature female to mature male parasites was 1.2:1. The lengths of female and male worms did not differ significantly.
记录了1997年3月至6月间在梅奥郡伊尼什基亚岛附近误捕的26只幼年灰海豹（Halichoerus grypus）体内瘤状吻钩绦虫（Acanthoceophala: Polymorphidae）的发生情况、寄生位置及性别比例。瘤状吻钩绦虫在海豹体内的寄生位置并无差异，所有虫体均在小肠中发现。感染率为100%，未记录到其他棘头虫物种。每只海豹体内瘤状吻钩绦虫的平均丰度为416条（范围80 - 846条）。丰度按月无显著变化。成熟雌虫与成熟雄虫的性别比例为1.2:1。雌虫和雄虫的长度无显著差异。
