Var. EUPHEATICUS, Boulenger. 



I am indebted to my son, Dr. C. L. Boulenger, for 8 specimens 

 obtained by himself and Lieut. Harrison at Bamadieh on the 

 Euphrates Front in 1917, which are highly interesting, 7 of them 

 differing from all others of the species in the subocular bordering the 

 mouth ; otherwise they agree with the typical form in the number of 

 scales on the body (38 to 43 across middle, 14 or 16 between the hind 

 limbs) and of femoral pores (23 to 27*). There are 22 to 27 caudal 

 scales in the fourth or fifth whorl. The first supraocular is broken up 

 into 2 or 3 parts, and in 4 of the specimens there is an azygos shield 

 between the prefrontals. 



Young with 4 white streaks on the upper surface of the body, 6 on 

 the nape, and one on each side, separated by broader black streaks, 

 each of which may bear a series of round white spots.
