28 eECEONID^. 



the first labial, and three nasals ; ten upper and eight or nine lower 

 labials ; mental triangular or pentagonal, not longer than broad ; 

 two pairs of chin-shields, median largest and forming a suture 

 behind the point of the mental. Body covered above with irregular 

 small flat scales and large trihedral subtriangular tubercles, forming 

 twelve or fourteen longitudinal series ; these tubercles are not so 

 large as in O. caspins, though likewise much larger than the 

 interspaces between them, the diameter of the largest not quite 

 equal to half that of the eye ; they are strongly keeled. Abdo- 

 minal scales large, cycloid-hexagonal, imbricate, smooth, in about 

 twenty longitudinal series in the middle of the belly. Male with 

 five or six prseanal pores. Tail feebly depressed, tapering, above 

 with rows of large spinose trihedral tubercles, inferiorly with a 

 median series of enlarged transverse plates. Sandy-coloured above, 

 brown-spotted ; tail with brown annuli ; lower surfaces white.

Differs from 0. scaher in the following points : — Limbs shorter ; 

 the fore limb reaches between the eye and the tip of the snout, the 

 hind limb to the shoulder. Dorsal tubercles smjiU, nearly equal to 

 the small ear-opening in size, forming ten longitudinal series. Nine 

 upper and seven lower labials. Praeanal pores four. In all these 

 characters this species approaches G. kotschyi, from which it differs 

 chiefly in the larger ventral scales, which are as in G. scaher. 

 The enlarged plates on the lower surface of the tail are about 

 equally long and broad, and many of them are divided into two. 

 Colour grey, with three rather imperfect longitudinal dusky bands 

 on the back, formed of arrowhead-shaped marks ; a dusky line, not 

 very strongly marked, from the eye to the shoulders. Size of G. 

 Tcotschyi.
