19. ScAPTEiBA ACUTiEOSTRis. (Plate IX. fig. 4.) 

 Scapteira aeutirostris, Boulenger, toni. cit. p. 114. 

 1 specimen (young). Nushki to Helmand. 



Snout conical, acutely pointed ; loreal region nearly vertical. Nasals slightly swollen, 

 lower not reaching the rostral, upper forming a long median suture ; frontal grooved 

 anteriorly ; three large supraoculars, forming sutures with one another ; first supraocular 

 in contact with the first supraciliary, the second loreal, the prsef rontal, and the frontal ; 

 second and third supraoculars separated from the supraciliaries and from the frontal by 

 a series of granules ; two or three minute granules between the first and second supra- 

 oculars; a small, band-like posterior supraocular, separated from the others by granules; 

 interparietal pentagonal ; no occipital, parietals forming a suture behind the inter- 

 parietal ; no enlarged scales on the outer border of the parietals ; temporal scales 

 granular, smooth ; no auricular denticulation ; subocular not reaching the lip, resting 

 on the fifth, sixth, and seventh upper labials ; the three anterior pairs of chin-shields in 

 contact ; collar straight, the marginal scales feebly enlarged. Dorsal scales minutely 

 granular, smooth, equal. Ventrals equilateral or longer than broad, in oblique longi- 

 tudinal series ; 35 transverse series, the longest of which contains about 20 plates. A 

 very large pra?anal plate, about twice as broad as long. The adpressed hind limb reaches 

 the posterior border of the orbit ; foot as long as the distance between the arm and the 

 anterior loreal ; digits flattened, smooth or indistinctly keeled inferiorly, strongly fringed 

 laterally ; the ungual lamellae much enlarged, forming a suboval disk ; a series of large, 

 transverse subtibial shields. 15-17 femoral pores. Upper caudal scales feebly keeled. 

 Sand-coloured above, with blackish network ; head with symmetrical black markings, 

 lower surfaces white.

This new species is allied to S. grammica (Licht.) ; diflPering by the large anterior 

 supraocular, the absence of enlarged shield on the outer border of the parietals, the 

 large praeanal, and the much larger subtibial shields.
