The specimens from Persia and the neighbouring parts of Meso- 

 potamia, N.E. of Bagdad, are distinguished by the larger occiijital, 

 which may be twice or twice and a half the width of the interparietal, 

 and the more extensive share taken by the subocular in the border of 

 the mouth, its lower border measuring \ to i the length of the upper, 

 rarely only \. The scales are a little larger on an average, there being 

 28 to 38 round the middle of the body, including the ventrals, usually 

 31 to 36. 23 to 30 transverse series of ventral plates, usually 24 

 28. 8 to 11, rarely 12, femoi-al pores on each side. 



The hind limb rarely reaches the ear. 



The collar is often more distinct than in the typical form, and 

 sometimes free across the throat. 



The black vertebal streak, instead of being confined to the nape, 

 sometimes extends along the whole body ; the space between the light 

 lateral streaks is sometimes red.*
