supraoculars, with a very small one behind, bordered anteriorly, 
externally, and internally with granules; the distance between

of the latter shield; interparietal small; no occipital; tem- 
poral scales granular, smooth; an enlarged scale on ‘the supero- 
anterior border of the ear; no auricular denticulation; lower 
eyelid opaque ; subocular bordering the lip, between the sixth and

across the middle of the body. Ventral plates forming irregular 
oblique longitudinal and nearly straight transverse series; the 
longest transverse series contain 18 or 20 plates, which are longer 
than broad; 38 transverse series. Preanal scales small, irregular, 
a few postero-median slightly enlarged. The adpressed hind limb 
reaches halfway between the collar and the ear; foot as long as 
the distance between the arm and the anterior border of the orbit; 
infradigital scales feebly keeled; an outer series of large transverse 
subtibial shields. 2] or 22 (19 to 23) femoral pores. Tail more
