last of which is in contact with the lirst scale of the supraorbital semi- 

 circle ; supraocular disks composed of seven enlarged scales, the inner 

 ones either in contact with the scales of the supraorbital semicircles 

 or separated from them by an incomplete series of granular scales ; 

 supraorbital semicircles broadly in contact with each other, separated 

 from the occipital by two very irregular series of scales ; occipital a 

 little smaller than the ear-opening ; the scales of the occipital region 

 considerably larger than the dorsals; canthus rostralis sharp, consist- 

 ing of four elongated scales, the anterior small ; superciliary ridge 

 consisting of one long anterior scale followed by a doulile series of 

 very small scales ; three or four rows of granules separating the super- 

 ciliaries from the supraocular disk; two medium-sized scales on the 

 inner border of the elongate superciliary and just in front of the 

 granules ; loreal rows four, the scales keeled ; subocular semicircles 

 keeled, broadly in contact with the supralabials ; supralabials eight or 

 nine, the suture between the sixth and seventh being under the center 

 of the eye; seven inf ralabials ; temporals granular, with a bare indi- 

 cation of a supratemporal line ; dorsals granular, keeled, with a median 

 double series of slightly larger ones ; ventrals imbricate, small pos- 

 teriorly and with a very faint indication of a keel, larger anteriorly 

 and with a somewhat more pronounced keel especially on the chest 

 scales ; those on the throat very small, rounded and elongate ; fore legs 

 above covered with sharply keeled scales, those on the upper arm as 

 large as the posterior ventrals, those on the lower arm a little larger 

 than the anterior ventrals ; anterior face of femur and underside of 

 tibia similarly covered, the scales of the former gradually decreasing 

 on the underside, the upper side of both being covered with granules 

 like those on the back; scales on fingers and toes sharply carinate ; 

 digital expansion moderate, about 22 lamellae on the second and third 

 phalanges of the fourth toe; tail long, compressed, the proximal half 

 with a high fin supported by about 14 bony rays ; caudal verticils 

 distinctly indicated by a vertical series of scales a little wider than those 

 surrounding them and with straighter posterior margins, those between 

 being pointed and narrower, in about seven irregular series, all imbri- 

 cate and keeled ; the scales covering the upper edge of the tail raised 

 and slightly spinous, forming a serrated ridge, about five spines cor- 

 responding to each verticil in the basal portion; dewlap large, with 

 distant series of scales, the anterior edge thickened; postanal scales 

 well developed ; a distinct nuchal and dorsal skin fold.
