This species may be divided into several ill-deiined varieties, the 

 two extremes being the var. xanthina, Gray, from Asia Minor and 

 Syria, and the var. deserti, Anders., from the confines of the Tunisian 

 Sahara — the former characterized by an obtusely pointed snout 

 covered with strongly keeled scales, the latter with a very short and 

 broad snout without canthus and covered with smooth scales. Certain 

 specimens approach the var. hugyi of V. aspis, and the species 

 is to a certain extent connected with V. runsellii through the var. 

 xanthina.
