As can be seen in the tables and maps, the geographic distribution for each of these characters reveals a similar pattern; that is, a clinal variation is evident for each one. Although in Israel we find populations which coincide with those from northern Africa, the Sinai specimens coincide with those from the Nile Arabian populations, specially those living in the centre of the peninsula, are defined by their large size (up to 90mm. of SVL), and strongly keeled and large dorsal scales, numbering 19 to 25 at midbody. Nevertheless, some Saudi Arabi-.
