The aim of present research is morphological study of versicolored wood snake, Hemorrhois ravergieri (Reptilia: Colubridae) in most provinces of Iran. It is non-venomous snakes that can be seen in the mountains and slopes, plains and semi-desert regions. We studied 34 snakes from different provinces of Iran. Sexes of specimens were identified with observation of hemipenis in live male snakes and dissection of fixed materials and study of testes and ovaries. Meristic characters were counted in scales under a stereomicroscope and metric characters were measured with caliper and ruler. In the results of this study, the average length and width of head and snout-vent in male snakes was more than females (P≤0.05). Also the number of ventral scales was 184-223 in all of specimens. The average number of ventral scales of adult specimens was 200.18 that counted 205.1 in the adult females and 196.08 in male specimens (P≤0.05). The number of dorsal scales of midbody was 21and anal divided in the all of specimens. There is no difference in the number of postoculars, preoculars, postnasal, prenasal and loreal scales between specimens.
