摘要
A micropaleontological analysis has been made on 123 samples taken from surface sediments of the northern Philippine Sea, NW Pacific (27.0°~30.0°N, 129.5°~135.5°E, water depth from 1 666 m to 6 616 m). A total of 35 species belonging to 21 genera has been found from 38 samples which were taken mainly from water depths shallower than 4 000 m. The ostracod fauna is dominated by cosmopolitan deep-sea species, of which Krithe is the most abundant. The other main components are Poseidonamicus, Henryhowella asperima, Cytheropteron, Pennyella, Aversovalva subformis, Pseudobosquetina mucronalatum and Legitimocythere acanthoderma. Three new species are described: Aversovalva paraformosa, Cytheropteron houae Zhao and Pennyella microreticulata.
