Two new species of Asterocheridae are described from Korean seas: Acontiophorus pilosus associated with a bryozoan of Celeporina sp. in the Sea of Japan and Asteropontius bifurcatus associated with the antipatharian Antipathes japonicus in Jeju Island in Korea Strait. A key to the species of Acontiophorus is provided.

Three new species of poecilostomatoid copepods are described as associates of the scleractinian coral Gardineroseris planulata (Dana) from the Moluccas: Sociellus geminus n. sp., Odontomolgus mucosus n. sp. and O. unioviger n. sp. The genus Sociellus is transferred from the Rhynchomolgidae to the Anchimolgidae. The previously described four species of the genus Paramolgus (P. angustus, P. eparmatoides, P. gibberulus, and P. setellus) of the Rhynchomolgidae, associated with Gardineroseris planulata, are transferred as well to the genus Anchimolgus in the Anchimolgidae.

Ergasilus zacconis (Yamaguti, 1936), the copepod parasite originally named as Pseudergasilus zaconnis, is redescribed based on the specimens newly collected from the freshwater fish Zacco platypus (Temminck and Schlegel) from Japan. Some errors appearing in the original description are emended. An explanation for the generic position of this species is given.

The auther investigated the distribution and seasonal variations of Copepods and Branchiopods in Myeongam Lake located in Cheongju City, Chungchungbuk Do. Air and Water temperature, pH, and the amount of dissolved oxygen were also measured eleven times from July 29 to November 5, 1977. The results obtained are as follows: 1. The mean values of air and water temperature, pH, and dissolved oxygen during the investigation period were $25^{\circ}C , $23.7^{\circ}C, 6.86, and 10.75 ppm, respectively. 2. The total number of species collected in this lake were 13 species (1) thermocyclops taihokuensis (Harada) (2) Thermocyclops hyalinus (Rehberg) (3) Mesocyclops leuckarti (Claus) (4) Diacyclops disjunctus (Thallwitz) (5) Paracyclops fimbriatus (Fischer) (6) Cyclops sp. a (7) Cyclops sp. b (8) Diaphanosoma brachyurum (Lievin) (9) Daphnia pulex Leydig (10) Daphnia longispina (O. F. Muller) (11) Daphnia sp. (12) Moina dubia De Guerne et Richard (13) Chydorus sphaericus (O. F. Muller) 3. Among these species, 4 species (1, 3, 8, 10) were collected continually throughout the investigation period. 4. The dominant species was Diaphanosoma brachyurum during the investigation period.

Acanthochondria spirigera is redescribed based on the specimens recovered from the Lophiomus setigerus in the southern coast of Korea. This parasitic copepoda is distinguished from congeners by the possession of spirally twisted egg-strings. Acanthochondria spirigera(Chondracanthidae, Poecilostomatoida) is the first recorded species from Korea. This parasitic copepod was not found on the fish in May. Relative density and prevalence also decreased from January to May. A. spirigera live symbiotically within the pharyngeal cavity of the L. setigerus, and eat oesophageal mucous string of their hosts. The male of the parasitic copepoda is dwarf, and found on the ventral surface of genital segment of the female.
