蛇类或高级蛇类组成一个由4个科组成的单系群：眼镜蛇科(11属70种)、游蛇科(300属1850种)、眼镜蛇科(65属270种)和蛇科(33属240种)。根据形态和分子数据对悬铃虫进行了初步分类，并列出了现存的悬铃虫科所有属。前尖牙的毒液系统(表现为一些Atrtaspididae、所有的Elapidae和所有的Viperidae)独立地进化了几次，并很早就出现在眼镜蛇科中。与前毒牙系统相比，后方毒液系统(由一些苍耳科和许多“游蛇科”所表现的)被研究得更少，尽管很明显，后毒牙“游蛇科”构成了一个多系群。毒液器官的其他组成部分--腺体和分泌物也表现出很大的变异性，这使得重建毒液器官的进化史变得困难。然而，在唇上区有浆液分泌细胞的存在，以及在最基本的高级蛇的现存谱系中存在分化的上颌牙列，强烈地表明毒器是游蛇总科的突触形体，而在少数“游蛇科”中它的缺失是次生损失的结果。
Colubroids or advanced snakes form a monophyletic group comprising four families: Atractaspididae (11 genera, 70 species), “Colubridae” (300 genera, 1850 species), Elapidae (65 genera, 270 species) and Viperidae (33 genera, 240 species). A preliminary classification of colubroids based both on morphological and molecular data is presented and all extant genera of “Colubridae” are listed accordingly. The front-fanged venom system (displayed by some Atractaspididae, all Elapidae and all Viperidae) evolved several times independently and appeared early within colubroids. The rear-fanged venom system (displayed by some Atractaspididae and many “Colubridae”) has been studied less than the front-fanged system, although it is clear that opisthoglyph “Colubridae” constitute a polyphyletic group. The other components of the venom apparatus, the glands and the secretions, also show great variability, rendering the reconstruction of the evolutionary history of the venom apparatus difficult. Nevertheless, the presence of serous secretory cells in the supralabial region and of a differentiated maxillary dentition within the most basal extant lineages of advanced snakes strongly suggest that the venom apparatus is a synapomorphy of the Colubroidea and that its absence in a few “Colubridae” results from secondary losses.
