diameter of the eye. The fore limb, stretched forwards, reaches the tip of the snout ; the 

 hind limb reaches the shoulder. Digits slender, shortly fringed laterally, with feebly 

 tricarinate inferior lamellae. Head covered with small granules, intermixed with 

 enlarged ones on the vertex, the occiput, and the temples ; rostral quadrangular, nearly 

 as broad as long, with median cleft above ; nostril pierced between the rostral, the first 

 labial, and two nasals ; ten upper and nine lower labials ; mental trapezoid, broader than 

 long ; no chin-shields ; gular granules minute. Back covered with small granules inter- 

 mixed with oval, very feebly keeled tubercles, forming about twelve irregular longitu- 

 dinal series. Ventral scales small, smooth, subhexagonal, imbricate. Tail cylindrical, 

 slightly depressed, verticillate, with subequal feebly keeled scales. Sand-coloured above, 

 with seven darker hands across the body, and dark brown bands across the tail ; head

Nearest S. orientalis, Blanf., from which it differs by the much longer snout, longer 

 limbs, larger and more numerous dorsal tubercles, smooth ventral scales, &c. 



[One specimen only of this new species was collected in Northern Baluchistan between 

 Nushki and the Helmand.— J. E. T. A.]

 Agamura persica, Blanford, torn. cit. p. 358; Boulenger, torn, cit. p. 51. 



These specimens show the differences between A. persica and A. cruralis, Blanford, to 

 be less important than was hitherto believed. The following notes are taken from the 

 specimens collected by Dr. Aitchison : — 



The fore limb being stretched forwards, the wrist reaches the tip of the snout, or half- 

 way between the latter point and the eye ; the hind limb reaches the ear, or halfway 

 between the ear and the eye, or (in a young male) as far as the eye. Rostral twice or 

 not twice as broad as high, completely divided into two, entering or not entering the 

 nostril; 12 to 14 upper and 9 to 12 lower labials ; mental not twice as broad as long, 

 sometimes with a shield on each side between it and the second infralabial. The enlarged 

 dorsal tubercles sometimes keeled and subtrihedral. Numerous enlarged tubercles on 

 the hind limbs. Male without or with two praeanal pores.
