摘　　要：分别利用常规方法和透明骨法制备四川裂腹鱼和昆明裂腹鱼的骨骼标本,对这两种裂腹鱼的骨骼系统进行比较分析。结果表明,四川裂腹鱼与昆明裂腹鱼骨骼系统间的差异较小,可能是种间亲缘关系较近的缘故。这两种裂腹鱼在某些骨骼如齿骨、前颌骨、前鳃盖骨上表现出一些明显的差异,这些特征可以作为种间的鉴别特征。The skeletal system of Schizothorax kozlovi Nikolsky and Schizothorax grahami were compared and analyzed by conventional and transparent bone methods.The results indicated that there is small difference between Schizothorax kozlovi and Schizothorax grahami,maybe because of relatively close genetic relationship.But on the certain skeletons have obvious differences in the two kind of Schizothorax,such as tooth bone,premaxilla,preopercle.These features could be used as discriminate features between the two kinds of species.
