| 摘 要： | 为探讨有尾目脊椎的划分,本文以小鲵科的山溪鲵(Batrachuperus pinchonii)为例,运用透明骨骼双色法对其脊柱的形态特征进行了观察,并对各部分椎骨特征进行详细描述和绘图.结果显示,山溪鲵的脊椎根据椎骨是否具前关节突、横突、肋骨、肋软骨和脉弓等形态特征可分5部分；同时结合小鲵科其他20种94号标本和蝾螈科6种27号标本的脊柱特征及文献资料,讨论了有尾目脊椎的划分,认为将有尾目脊柱划分为5部分(颈椎、躯椎、荐椎、尾荐椎和尾椎)的观点较将其划分为4部分(颈椎、躯椎、荐椎和尾椎)的观点更合理. |

| Abstract: | To discuss the division of the vertebral column in Urodela, the vertebral column characteristics of Batrachuperus pinchonii (Hynobiidae) was studied by a clearing and double staining method as a case in the present paper, and the morphological characteristics of each section of the vertebral column were described. The results showed that the vertebral column of B.pinchonii could be divided into five sections based on the morphological characteristics of vertebra. At the same time, combined with the vertebral column characteristics of 94 specimens from 20 species of other hynobiid salamanders and 27 specimens from 6 species of salamandrids and literature, the division of vertebral column in Urodela was discussed. The results show that it is reasonable to divide the vertebral column of Urodela into five sections, including cervical vertebra, truck vertebra, sacral vertebra, caudosacral vertebra and caudal vertebra. |
