Acanthodadylus. lOl 



small scales on the inner side in the other, fourth broken up into 

 small scales or granules ; one or two series of granules between the 

 second supraocular and the superciliaries, two or three between the 

 third and the superciliaries, which are 4 to 6 in numlier ; a series of 

 granules usually separates the parietals behind the interparietal. Ear 

 with 3 to 5 long pointed lobules. 31 to 42 gular scales in a straight 

 line. 



Dorsal scales very small, rouudish-subrhomboidal, flat or feebly 

 convex, rather strongly keeled, laterals, above those that merge into 

 the ventral plates, very minute ; G6 to 80 scales across the middle of 

 the body. Ventral plates mostly as long as broad or longer than 

 broad, not forming longitudinal series, in 31 to 37 transverse series, 

 the broadest of which contain 16 plates. A more or less enlarged 

 preanal plate. 22 to 29 femoral pores on each side. 25 to 30 feebly 

 unicarinate lamellae under the fourth toe. 36 to 40 scales in the 

 fourth or fifth caudal whorl. 



Yellowish or reddish sand-colour, with faintly marked reticulation 

 and light and dark dots as in the typical A. scutellatus.

Three male specimens, from Wargla, form part of the Lataste 

 Collection. A fourth was obtained not far from Wargla, between the 

 Wed IST^a and El Alia, near Guerrara, by Dr. E. Hartert in 1912, and 

 a fifth at El Wed, E. of Tuggurt, by Mr. Harding King in 1909. This 

 is probably the larger variety observed by Werner (I.e. 1894) between 

 Mraier and Temacin. 



Var. AUDOUINI, Boulenger. 



A female from Wadi Haifa (Anderson Collection) agrees pretty 

 well with one of the figures of L. olivieri of Audouin, and as it differs, 

 as well as the specimens from the same locality associated with it, by 

 a lower number of scales, which are rather strongly keeled, I have 

 decided to U2:)hold Audouiu's lizard in a varietal sense, although the
