摘　　要：长尾大眼鲷颅骨较长,背面下凹较深。无眶上骨,有眶下骨架。上筛骨宽大,伞形。犁骨具齿。额骨背视"儿"形。顶骨和上枕骨发达。有后颞窝。前颌骨和齿骨有小钩齿。腭骨无齿。鳃耙有小齿,第1咽鳃骨无齿,第2、3、4咽鳃骨有密集小齿。有上后颞骨,腰带骨基部愈合。The present paper deals with the morphology of skeleton in spotfin bigeye Priacanthus tayenus, reference with Osteichthyes. The neurocranium, pectoral girdle, pharyngeal bone in spotfin bigeye are shown to be similar to those in Percoide fishes in morphology. There are 6 suborbital bones, including developed lachrymal, with suborbital shelf but without supraorbital bone. The supraethmoid, parietal and supraoccipital are larger. There are many small teeth in vomer, premaxilla, dentary, and the second, third, and fourth pharyngobranchial and pharyngeal bones. The supraposttemporal is found, and the pelvic girdles are fused in their base.
