摘要
比较了鲐 Pneumatophorus japonicus ( Houttuyn)和蓝点马鲛 Scomberomorus niphonius( C.etV.)的骨骼特征。鲐脑颅整体特别是前 1/ 2部分狭长 ,蓝点马鲛脑颅较扁宽。鲐脑颅的中筛骨、鼻骨、额骨、犁骨、围眶骨等 ,咽颅的前上颌骨、上颌骨、腭骨、齿骨、角舌骨、尾舌骨、下咽骨等 ,肩带的上后颞骨、后匙骨和腰带骨等与蓝点马鲛相应部分的骨骼皆有重要差异 。
The skeleton of Pneumatophorus japonicus is described and compared with the Scomberomorus niphonius. There are many different features which the apparent differences of the whole skull and isolated bones can be seen in the following: 1.Nasal narrow in Pneumatophorus japonicus but broad in Scomberomorus niphonius. The 4th suborbital is normal in Pneumatophorus japnonicus but the 4th suborbital is formed suoorbital shelf in Scomberomorus niphonius. This suborbital shelf is possibly a character of the Family. 2.The features of Premaxillary, Maxillary, Palatine, Opercle, Urohyal, Pharyngeal bones……of two species (have many features) are probaly used to identify the Family or Genea. 3.The Postcleithrum has more differences of the species which are probably the features of the Family or Genea.
