 in females; but in four males examined by Peracca it reaches the 

 collar or a little beyond, the variation being therefore as in the 

 specimens from Eg}pt. 



62 to 66 scales across the middle of the body, 30 to 34 transverse 

 series of ventral plates, 11 to 14 plates in the collar, 15 to 24 femoral 

 pores, 17 to 19 lamellae under the fourth toe. 



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

 except in one male from Beersheba.

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

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

 Paris Museum, appears to be referable to it. 

 This is the Laceria detedi of Milne-Edwards.

The large massive form inhabiting the Plateaux of .Algeria, for 

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

 1885, is very nearly related to the typical form, but differs chiefly in 

 the smaller ventral plates, which are but little broader than lon^, 

 none of them ever 1:wice as broad as long, and form 14, exceptionally 

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

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

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

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

 middle, the median plates usually barely differentiated from the ;,'ular 

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

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

 supraocular sometimes entire, more frequently bisected. In one 

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