Eighteen larvae and young of the flatfishes belonging to the subfamily Bothinae measuring 16 to 56mm. in total length were collected from tropical and subtropical areas of the Indo-Pacific Ocean including the southern coast of Japan during the period from March, 1960 to January, 1961. Examination of these collections has led us to the conclusion that they may be referred tentatively to the following three species and one genus: 1) Arnoglossus japonicus HUBBS (Fig. 1); 2) Crossorhombus valde-rostratus (ALCOCK) (Figs. 2-3); and 3) Bothus myriaster (TEMMINCK et SCHLEGEL). Moreover, a larval form was recognized as Bothus, but could not be assigned to either myriaster or pantherinus (RüPPELL) (Fig. 4). The metamorphosed postlarvae of Crossorhombus are here reported for the first time. An analytical key for identifying the postlarval form of this group of fish occurring in the waters around Japan is tentatively presented mainly based on the counts of vertebrae and dorsal, anal and pectoral fin rays in numerous adult speciemens of twenty-four species, which are believed to be found in the same waters.
