strongly keeled scales resembling those of A. loshianus, Daud., 

 increasing in size to the root of the tail ; generally 10 to 16 rows 

 of enlarged scales between the thighs ; 38 to 57 scales round the 

 body; 12 to 14 ventral plates, broader than long, the higher 

 number being the most prevalent, but, as the ventrals pass very 

 gradually into the scales on the sides, it is sometimes difficult to 

 define the line of separation. An enlarged preeanal surrounded by 

 large scales, but occasionally broken up. 17 to 24 femoral pores. 

 The fore limb is well developed, and reaches to the extremity of 

 the snout. The digits have an upper, an inferior and a lateral 

 plate to each of their sides ; claws moderately long, compressed, 

 and sharply curved. The hind limb reaches to between the eye 

 and the ear, and even in advance of the eye, and its digits are long 

 and tapered, as in A. scutellatus, Aud. ; the fringe is long as in 

 that species, and is longest on the outer edge of the digits ; the 

 hind claws are long, tapered, and little curved. 



The coloration is much the same as in A. hoskianus, Daud. 

 The adult may be uniform olive, greyish, or even brownish, some- 

 times sparsely covered with smaxl black spots, tending to a 

 longitudinal arrangement in lines. The young is lineated with 

 eight black and seven white bands. The upper surfaces of the 

 limbs are generally covered with white spots on a dark ground, 

 and, in some semi-adults, there is a dark line along the back of 

 the thigh. Underparts white. 



The typical form, from Sind and the Helmund, is considerably 

 larger than any of the specimens from South-Eastern Arabia. 

 A male from the former region measures 74 millim. from the 

 snout to the vent, whereas, from the latter locality, the largest 

 male is only 59 millim. Besides this diflference in size, the typical 

 form has a somewhat longer, narrower, and more pointed head 

 and snout, but specimens are met with in which the head is not 

 so pointed, and in which the snout becomes obtusely rounded, 

 while in some examples from Sind the head is even still shorter, 

 but with a pointed snout. Specimens from Southern Persia 

 attain also to a greater size than those from Arabia, but fall 

 short of the dimensions of the Helmund lizards. The heads of 

 lizards of this species from Jask approach in their form more to 

 the Arabian than to the Sind specimens, the head being rather 

 short and broad, with a pointed snout, varying in the degree to 

 which the nasal portion is widened. There is also a marked 

 difference between the form of the head when the two extremes
