摘　　要：常规方法和透明骨法制备昆明裂腹鱼的骨骼标本,记录观测结果并拍照,对其骨骼系统进行描述。其特征为脊椎数目在46～47之间,肋骨在18～19之间,咽骨上有三排咽齿,齿式呈2:3:5式。骨骼系统的形状和变化可以为裂腹鱼亚属的分类及演化提供分类方面的基础资料。The skeletal system was prepared by conventional and transparent bone methods.Observation results and pictures were recorded.The description for the skeletal system of Schizothorax grahami(Regan) can provided the reference for Schizothorax.The characteristics of columna vertebralis is made up of 46 to 47,the costale between 18 to 19.Pharyngeal bone has three rows of pharyngeal teeth,the dental formula of S.grahami is 2:3:5.These features and changes of skeletal system can be used as classification and evolution features to Schizothorax.
