二长棘鲷和黄鳍鲷骨骼系统的比较

A Study on Osteology of Parargyrops edita Tanaka and Sparus latus Houttuyn

对二长棘鲷和黄鳍鲷的骨骼系统进行了比较研究。结果表明,二长棘鲷脑颅中的上筛骨、侧筛骨、额骨、眶下骨、蝶耳骨、上枕骨,咽颅中的前上额骨、腭骨、舌额骨、齿骨、鳃盖骨、尾舌骨、咽鳃骨等与黄鳍鲷相应部分的骨骼有明显差异,某些特征可作属间或种间的鉴别依据。

The present paper deals with a comparative study on the skeleton systems of Parargyrops edita and Sparus latusa. The results reveal that obvious differences exist between them as follows： （1） between the two species there are morphological differences in many bones of neurocranium, such as supraeethmoid, Laterai ethmoid, frontal, suborbital bones, sphenotic, supraoccipital, etc. （2） As for splanchnocranium, the feature of premaxilla, palatine, hyomandilular, dentary, opercular, urohyal and pharyngobranchial are different between them. These characters of skeletons can be used as some important basis for identifying genera or species.
