چکیده

Two species of the family Colubridae were compared based on cranial osteology. The specimens were from Kermanshah Province (2010–2012). We compared the skulls of the two species and distinguished their differences. According to our study, eight elements of the skull are clearly different between the two species. We speculate that these differences are related to different diets, prey size, or result from evolutionary processes that adapt these species to special conditions or competition with other sympatric species. Differences and characteristics of the above species help to facilitate their identification and evaluate phylogenetic studies in relation to skull morphology.
