对鲳亚目的印度无齿鲳、银鲳、三刺低鳍鲳和刺鲳的骨骼系统作了详细的比较。研究结果表明，4种鱼类脑颅中的鼻骨、上筛骨、侧筛骨、眶下骨、蝶耳骨、翼耳骨、上耳骨和前耳骨等均有明显的差异；咽颅中的前颌骨、上颌骨、舌颌骨、尾舌骨、鳃盖骨、咽鳃骨和下咽骨等也有显著的区别；附肢骨骼中的肩带骨和腰带骨也各有不同。这些差异可作为种间的分类依据。%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 .
