MR. G-. A. BOULEXGER OX THE VARIETIES OP 



Specimens from the Atlas of Morocco have been figured by me in s Novitates 

 ZoologicEe,' xii. 1905, pi. ii. ; one from Tlemsen, near Oran, is represented on PI. XXIX. 

 fig. 10. 



Var. vaucheri. 



Like the preceding, this variety differs but little from the typical form, the principal 

 distinction being in the smaller scales. 



The head is rather short, not more than once and a half as long as broad, and 

 moderately depressed, its depth, in the tympanic region, equalling the distance between 

 the eye and the tympanum. The hind limb reaches the shoulder in males, the elbow 

 of the adpressed fore limb in females ; foot once and one-sixth to once and one-third 

 the length of the head. 



Head-shields as in the typical form, but parietals rather shorter, usually but little 

 longer than broad; series of granules between the supraciliaries and the principal 

 supraoculars complete, or first supraciliary in contact with the second supraocular ; 

 parietal in contact with the upper postocular, except in one specimen; masseteric 

 shield present, except in one specimen ; four upper labials anterior to the subocular 

 (one specimen has five on one side, another has three). 



Dorsal scales finely granular, distinctly keeled, 61 to 73 1 across the middle of the 

 body, 3 and 4 transverse series corresponding to one ventral plate, 36 to 50 2 to the 

 length of the head. Ventral plates in 6 longitudinal series. Scales on upper surface 

 of tibia a little smaller than dorsals. 23 to 26 3 lamellar scales under the fourth toe. 

 Upper caudal scales moderately or strongly keeled, truncate or very obtusely pointed 

 posteriorly. 



Olive-grey above, with small black spots or reticulations ; a more or less defined 

 dark lateral band, bordered above by a whitish streak or series of white spots ; no 

 vertebral line or median series of spots ; hinder side of thighs with round white spots ; 

 two series of white, black-edged spots along each side of the tail ; belly uniform white 

 in both sexes, or with a few scattered black dots ; throat with black dots.
