As regards the colorationf the light spots are more or less effaced,

The habitat of the typical form extends from Palestine to Tripoli. 

 A female species from the French Sudan (coll. Dybowski), in the 

 Paris Museum, appears to be referable to it. 

 This is the Laceria deserti of Milne-Edwards. 



Var. BEDRIAGiE, Lataste. 



The large massive form inhabiting the Plateaux of Algeria, for 

 which I use the name iu the restricted sense adopted by Lataste in 

 1885, is very nearly i-elated to the typical form, but differs chiefly in 

 the smaller ventral plates, which are but little broader than long, 

 none of them ever twice as broad as long, and form 14, exceptionally 

 12 or 16, longitudinal and 31 to 36 transverse series. The scales are 

 convex or fiat, juxtaposed or subimbricate posteriorly, smooth or very 

 obtusely keeled, and number 53 to 63 across the middle of the body. 

 10 to 15 plates iu the collar, which is angular aud attached in the 

 middle, the median plates usually barely differentiated from the gular 

 scales. 26 to 36 gular scales iu a straight line. 16 to 23 femoral 

 pores ou each side. 18 to 21 lamellae under the fourth toe. First 

 supraocular sometimes entire, more frec[uently bisected. In one 

 specimen, from El Guerah, and in one labelled Algeria, the subocular

 Edwards' Lacerta deserti. 



t A specimen from Beersheba is figured in P.Z.S. 1881.
