The living specimens used for this study were towed horizontally by theHensen egg-net at Yangpow Bay, Hainan Island, from April 25th to May 25th,1963. The surface water temperature in the area where specimens were collec-ted varied from 28-30℃,and the salinity of the surface water from 30.70-31. 62‰. Altogether eight species of eggs and pre-larvae have been identified anddescribed briefly here. They are: 1) Etrumeus micropus, 2) Kowala coval, 3)Clupanodon punctatus, 4) Anodontostoma chacunda (Clupeidae), 5) Sillagosihama (Sillagimidae), 6) Lethrimus nematacanthus (Lethrimidae), 7)Paraprisipoma trilineatum (pomadasyidae) and Callionymus sp. (Callionymidae).Except Paraprisipoma trimineatum, the occurrence of the eggs and larvae ofthe other seven species are recorded for the first time in South China Sea alongthe coast of China. All the eggs of these eight species of fishes are bouyant and spherical.Except Callionymus sp.which bearing hexagonal reticulations on the egg membr-ane, the egg membranes of other seven species are smooth and thin, The-yolk granules of the eggs of paraprisipoma trilineatum and Callionymus sp. arehomogeneous,while those of the other 6 species are all with prominent segmen-tations.
