Helminth parasites, 11 species of trematodes, 4 species of cestodes and 6 species of nematodes, are described from marine planktonic invertebrates collected in Japanese waters and the East and South China Seas. The trematodes are: a Guschanskiana sp. Metacercaria (Accacoeliidae) from Sagitta enflata; Tetrochetus sp. Metacercariae (Accacoeliidae) from S. enflata, S. macrocephala and Sagitta sp.; Accacoeliidae gen. sp. metacercariae I, possibly of the genus Accactadium, from S. crassa f. naikaiensis, S. enflata, S. hexapera, S. macrocephala, Sagitta sp. and chaetognaths; Accacoeliidae gen. sp. metacercariae II from S. crassa f. naikaiensis; an Accacoeliidae gen. sp. metacercaria III, perhaps belonging to the genus Accacladocoelium, from S. crassa f. naikaiensis; Tergestia sp. metacercariae (Fellodistomidae), probably of T. laticollis (Rudolphi, 1819) Stossich, 1899, from S. crassa f. naikaiensis; Lecithocladium sp. metacercariae (Hemiuridae), possibly of L. excisum (Rudolphi, 1819) Lühe, 1901, from S. enflata, S. nagae and Sagitta sp.; a Parahemiurus sp. metacercaria (Hemiuridae) from a chaetognath; Hemiuridae gen. sp. metacercariae, related to the subfamily Dinurinae, from heterokrohnia sp., Sagitta sp. and chaetognaths; metacercariae of Pseudopecoelus japonicus (Yamaguti, 1938) von Wicklen, 1946 (Opecoelidae), from Euphausia similis; and a Paronatrema sp. metacercaria (Syncoeliidae) found free in a plankton haul. The cestodes are: Echinobothrium sp. larvae (Diphyllidea: Echinobothriidae) from Leptochela sp. pasiphaeids; Scolex pleuronectis Mueller, 1788 (Tetraphyllidea), from Sagitia sp.; Phyllobothriidae gen, sp. larvae (Tetraphyllidea) from Eukrohnia hamate and S. crassa f. naikaiensis; and larvae of Pseudonybelinia odontacantha Dollfus, 1966 (Trypanorhyncha: Tentaculariidae) from Euphausia recurva. The nematodes are: a larva of Anisakis sp. larva (Ⅰ) of Berland (1961) (Ascaridoidea: Anisak idea) from Euphausia nana; and Thynnascaris spp. larvae (Anisakidae) classified into five different types from S. crassa f. naikaiensis, S. nagae and Calanus sinicus. The metacercarial development including progenesis in E. similis and the life cycle of P. japonicas are discussed. The systematic position of P. odontacantha is discussed, and a diagnosis of the genus is given. A list of some other helminth or metazoan parasites obtained is appended.
