This is the second part of a series of papers dealing with marine copepods of the South China Sea collected not far off the coast of Kwangtung Province. It comprises of 31 species of Calanoida, of which 8 species belong to two genera of the family Euchaetidae and 23 belong to 5 genera of the family Pontellidae. The majority of the species are tropical in nature, but 16 of them extend to the East China Sea, 11 to the southern Yellow Sea and only 4 are restricted to the South China Sea. A species of Pontellopsis is found to be new to science, and Pontellopsis macronyx A. Scott and Euchaeta spinosa Giesbrecht are for the first time recorded from the South China Sea. Besides descriptions of the above mentioned species, some supplementary notes for the males of Euchaeta wolfendeni A. Scott, Euchaeta longicornis Giesbrecht and Pontellopsis regalis (Dana), which have not been previously obtained from the East China Sea and the Yellow Sea (Chen & Zhang, 1965) are also given.
