摘　　要：　本文对王锦蛇Elaphecarinata和红点锦蛇E.rufodorsata的形态特征及染色体的相对长度、臂比指数和Ag-NORs进行了比较分析。两种锦蛇在形态特征上存在明显差异,染色体相对长度和臂比指数存在明显差异;两种锦蛇的Ag-NORs无差异。讨论了锦蛇属的核型,银带在分类特征上的意义。The paper compares the morphological , karyotypical and Ag-NORs characters of Elaphe. Carinata and E. rufodorsata .There are distinct differences between the two species in morphological character and the relative length, arm ratio. It also discusses the significance of the karyotype and Ag-NORs of the genus in taxonomy.
