the louL^er ; temporal scales granular or hexagonal, smooth or keeled ; 

 tvmpiiuic shield present or absent ; 3 to 5 rounded or pointed projecting 

 lobules in front of the ear. 



4 pairs of chin-shields, the first or first and second* meeting in the 

 middle ; 30 to -43 gular scales iu a straight line between the symphysis of 

 the chin-shields and the median collar-plate ; gular fold feebly marked 

 or absent. Collar feebly curved, with 6 to 11 rather large plates. 



Scales granular and feebly keeled on the nape, rhombic, subimbricate, 

 ant.! strongly and diagonally keeled on the back, larger and smooth 

 towards the ventrals, 42 to 62 across the middle of the body. Ventral 

 plates mostly broader than long, in 12, very rarely 10, straight 

 longitudinal and 27 to 32 transverse series. One or two more or less 

 enlarged median preanal plates, bordered by smaller plates. 



A series of transversely enlarged, hexagonal, smooth or obtusely 

 keeled plates on the upper surface of the arm. Upper surface of tibia 

 with keeled scales similar to the dorsals or a little smaller ; lower 

 surface with one series of large and two of small plates. 13 to 21 

 femoral pores on each side, the two series meeting or narrowly sepa- 

 rated in the middle.t Digits similar to those of Acanthodactylas 

 vulgaris, with three series of scales, feebly serrated on the sides ; sub- 

 digital lamellse unicarinate, 21 to 26 under tlie fourth toe. 



Caudal scales oblique, strongly and diagonally keeled, the upper 

 rounded or obtusely pointed behind, 24 to 29 iu the fourth or fifth 

 whorls behind the postanal granules. 



Young blackish above and on the sides, with round white spots and 

 5 longitudinal white streaks, the vertebral bifurcating on the nape and 

 ending on the base of the tail, the dorsolateral starting from the 

 superciliary edge, the lateral from below the eye and passing through 

 the tvmpanum ; round white spots on the limbs. 



Adult greyish, yellowish, or reddish brown above, with a dark brown 

 or black band, spotted with white, along each side of the back, two 

 or three series of brown or black spots or ocelli on the sides, and a dark 

 vertebral streak on the nape, or with 4 or 6 longitudinal series of 

 ocellar spots ; hind limbs with large round white, dark-edged spots. 

 Lower parts white.

* Exceptionally '6 according to Werner. — i cliiu-shields on one side and 5 on 

 the other in one specimen examined by me (S. Africa). 



t Milne-Edwards's statement that there are only 9 femoral pores is evidently 

 due to a misprint.
