Abstract

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. These differences are speculated to relate to different diets, prey size or concluded from an evolutionary processes to adapt especial 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.

伊朗颈颈蛇与颈颈蛇(蛇纲:蛇科)颅骨比较
基于颅骨骨学对两种蛇科动物进行了比较。标本来自Kermanshah省(2010-2012年)。我们比较了这两个物种的头骨,区分了它们的不同之处。根据我们的研究,这两个物种的头骨有八个元素明显不同。据推测,这些差异与不同的饮食、猎物大小或适应特殊条件或与其他同域物种竞争的进化过程有关。上述物种的差异和特征有助于促进它们的识别和评估与头骨形态学有关的系统发育研究。
