Abstract
The aim of this research is study about filogenetic interpretation of colubride snake based on structure of rear fang and skeleton components.The twelve species the colubride snake was giving life for. This research was conducted by observed of rear fang character and skeleton components, include os frontal, parietal, maxilla, palatine, pterygoide, quadrates, basi-parasphenoide and basioccipitaleBased on the similarity and difference of taxonomic characters, this research can assumed that filogenetic position of twelve colubride species divided in three groups. The first groups consist of primitive colubride i.e: Elaphe flavolineata, Elaphe radiate, Elaphe oxycephala, Dendrelaphis pictus, Ptyas korros, Ptyas mucosus, Natrix piscator, Natrix subminiata and Natrix vittata. The second consist of only one species, Boiga dendrophila. The most advance group consists of E. enhydris dan H. buccata.
