rectangular scales, the lowest one continued backwards, completely 

 separating the suboculars from the upper labials; nostrils lateral, 

 somewhat elevated, with four rugose scales between the supranasals; 

 rostral nearly four times as broad as deep, a little narrower than 

 the mentals, incompletely separated from the nasal scales by a row 

 of small scales; frontal region with broad low ridges covered with 

 large, nearl}'^ smooth, rhomboidal scales which converge anteriorly 

 and surround a median group of six smaller, very unequal scales; 

 scales of the frontal ridges continuous posteriorly with those of the 

 supraorbital semicircles which are in contact; supraorbital region 

 covered with three longitudinal rows of keeled scales, the inner 

 (largest) row incompletely separated from the supraorbital semi- 

 circles by a partial row of small scales, the outer (smallest) row

separated from the superciliaries by two or three rows of granular 

 scales; occipital scale moderate in size, separated from the supra- 

 orbital semicircles by two scales; eight supralabial scales, each with 

 a deep longitudinal median groove bordered below by a sharp keel 

 in all except the two anterior ones; suture between sixth and seventh 

 supralabial below center of eye; subocular semicircle composed of 

 eight or nine keeled scales, separated from the supralabials by one 

 row of elongate, keeled scales; a pair of triangular mentals closely 

 in contact medially, their outer borders extending slightly beyond 

 those of the rostral; eight or nine smooth infralabials, the first six 

 subequal, the last ones quite small; a row of malar scales, quite 

 distinct anteriorly where they border the mental and infralabials, 

 becoming indistinct posteriorly and merging with the other rows of 

 scales which border the posterior infralabials; temporal region granu-
