Previously undescribed cystophorous cercariae which develop in sporocyst germinal sacs in the tectibranch opisthobranch Philine denticulata (Adams) are shown to be cercariae of Hemiurus luehei Odhner, 1905 (Hemiuridae), a common stomach parasite of clupeid and salmonid fishes off the Atlantic coast of Europe, in the Baltic and the Mediterranean Sea. The free-swimming cercariae are seized by calanoid copepods. Temora longicornis (Müller) and Acartia tonsa Dana acted as suitable experimental intermediate hosts. Pressure by the copepod mouth appendages causes delivery tube eversion and the injection of the cercarcial body into the haemocoel. Sagitta sp. was found naturally infected with a metacercaria of H. luehei. The cystophorous cercaria and metacercaria are described using light and scanning electron microscopy. Adults from herring were examined under the stereoscan electron microscope.
先前未描述过的囊蚴尾蚴在栉鳃后鳃类的有齿海蜗牛（亚当斯）的胞蚴胚囊中发育，现已证明其为吕氏半尾吸虫（奥德纳尔，1905年）（半尾科）的尾蚴，吕氏半尾吸虫是欧洲大西洋沿岸、波罗的海和地中海中鲱科和鲑科鱼类常见的胃寄生虫。自由游动的尾蚴被哲水蚤类桡足类动物捕获。长角哲水蚤（米勒）和汤氏纺锤水蚤（达纳）作为合适的实验中间宿主。桡足类口附肢产生的压力导致输送管外翻，并将尾蚴体注入血腔。发现箭虫自然感染了吕氏半尾吸虫的后尾蚴。使用光学显微镜和扫描电子显微镜对囊蚴尾蚴和后尾蚴进行了描述。对鲱鱼的成虫进行了立体扫描电子显微镜检查。
