As a series of reports on the type specimens of Amphibia and Reptilia deposited in the Herpetological Museum of the Chengdu Institute of Biology (CIB), Chinese Academy of Sciences, this study focuses on the serpent families excluding Viperidae. In China, there are over 180 species of snakes in 57 genera and eight families (Zhao, 2006), excluding the family Viperidae. In the Museum of CIB, the type specimens of these snakes belong to 11 species in 10 genera and three families (Xenopeltidae,Xenodermatidae and Colubridae).

In China, there are over 180 species of snakes in 57 genera and eight families (excluding the family Viperidae). In the Herpetological Museum of the Chengdu Institute of Biology (CIB), Chinese Academy of Sciences, the snake type specimens represent 11 species in 10 genera and three families (Xenopeltidae, Xenodermatidae and Colubridae).

As a series of reports on the type specimens of Amphibia and Reptilia deposited in the Herpetological Museum of CIB, this paper focuses on the serpent families excluding Viperidae in the collections at this Museum.

Researchers from Yibin University and Chengdu Institute of Biology, Chinese Academy of Sciences cooperated to study this job.
