Abstract The skeletal characteristics of four Stromateoidei fishes including A riomma indica ,Pampus ar-genteus , Peprilus triacanthus and Psenopsis anomala were studied .The results showed that obvious differences existed in neurocranium among four Stromateoidei fishes ,for example ,the shapes of nasal ,up-raethmoid ,lateral ethmoid ,suborbital bones ,sphenotic ,pterotic ,epiotic and prootic with subocular shelf in P .anomala .In splanchnocranium ,there were many bone differences in shape ,such as premaxilla ,max-illa , hyomandibular , urohyal , opercular , pharyngobranchial and pharyngeal . In pectoral girdle , these bones were not alike such as supraposfthemporal ,supratemporal ,supracleithrum and postcleithrum .In Pelvic girdle ,without ventral fin in P .triacanthus ,but there were a pair of two-forked bones in abdominal wall ahead the anus .These differences can be used in classification for inter-species .
