slightly rugose; nasals generally forming a suture; frontonasal 
hexagonal, broader than long, followed by a pair of preefrontals ; 
frontal hexagonal, broader anteriorly ; interparietal small, inclosed 
between the two pairs of parietals, of which the posterior is the 
largest; occipital small, elongate subtriangular; four supraoculars, 
anterior largest ; four or five supraciliaries ; lower eyelid opaque; a 
loreal, a larger preorbital; four infraorbitals, second descending to 
the lip, separating the fourth and fifth, or the fifth and sixth 
labials ; temporals in two or three rows; two projecting compressed 
scales in front of the ear; six or seven upper labials; rostral 
pentagonal, nearly three times as broad as high. Mental with 
straight posterior border ; six lower labials, posterior largest and 
keeled, in contact with five large shields. Gular scales small, 
elongate anteriorly, granular medially, increasing in size, and im- 
bricate, towards the collar ; latter angular, attached in the middle; 
sides of neck folded. Back covered with small flat roundish sub- 
triangular feebly keeled tubercles forming regular longitudinal and 
transverse series separated by minute granules; the tubercles 
becoming smaller and passing into the granules on the flanks; a 
lateral fold. Ventral scales large, quadrangular, broader than long, 
juxtaposed, forming twelve or fourteen longitudinal and thirty-three 
or thirty-four transverse series. Preanal scales rather irregular, 
generally a posterior pair enlarged. Limbs above with imbricate 
strongly keeled scales, inferiorly with smooth or granular scales. 
Femoral pores in two or three rows in the males, the inferior row 
composed of six to ten pores. Caudal scales smooth or feebly keeled 
inferiorly, strongly keeled above, and spinose on the sides; on the 
upper surface a whorl of large scales alternates with a whorl of smaller 
ones. Brown, blackish, reddish, or olive above, with darker or lighter
