The specimens from South Arabia, all of smaller size, females 45 

 millim. long from snout to vent being gravid, agree with the typical 

 form in the large size of the dorsal scales (27 to 35 across the middle 

 of the body), but differ in having the ventral plates in 14 (rarely 16) 

 longitudinal series, the outermost being usually feebly keeled. The 

 gular scales are large (24 to 30 in a straight line). 



Young usually with 6 white streaks on the nape and anterior part 

 of the back, 4 on the posterior part of the back, 3 on the base of the 

 tail, and one on each side ; sometimes 6 or 7 white streaks on the nape, 



5 on the anterior part of the back. One specimen has 6 white streaks 

 on the nape, the median pair uniting, at the level of the collar, into a 

 vertebral streak edged with black, the rest of the back being grey with 



6 rows of small white spots. Tail blue. Full-grown specimens 

 uniform olive, greyish, or brownish above, sometimes sparsely covered 

 with small black spots, which may have a longitudinal serial 

 arrangement.
