415 MR. G. A. BOULENGER ON THE VARIETIES OF 
Specimens from the Atlas of Morocco have been figured by me in ‘ Novitates 
Zoologice,’ xii. 1905, pl. ii.; one from Tlemsen, near Oran, is represented on Pl. 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 731 across the middle of the 
body, 3 and 4 transverse series corresponding to one ventral plate, 36 to 50? 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% 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.
