In this study, which has been done in Moghan Steppe, Damghan and Sari populations; 48 specimens were collected at midnight by hand. Present study was conducted on the basis of morphologic, morphometric and meristic characters of subspecies Cyrtopodion caspium caspium. We show that Moghan population in Northwest of Iran is isolated from two other populations in northeast of Iran.
