behind rostral, broader than long; prefrontals separated from the 

 canthals by a wedge-shaped scale; two heavy rounded can thai scales 

 followed by four elongate superciliaries ; six distinctly ridged supra- 

 oculars, the posterior one quite small, separated from the superciliaries 

 by one row of small keeled scales; occipital very small, bordered by 

 two distinct pairs of parietals on each side, the inner about eight times 

 the area of the occipital and about one-third that of the outer pair; 

 no distinctly enlarged latero-nuchals beyond the outer parietals; three 

 very elongate upper and five lower labials to a point below the center 

 of the eye; temporal scales increasing posteriorly in size, the last one, 

 just above and in front of the ear, abruptly larger and very conspic- 

 uous; anterior border of the ear with three large, coarse, projecting 

 scales. Dorsal scales large, imbricate and moderately mucronate, 

 laterals considerably smaller than the dorsals ; ventrals equal to dorsals 

 in size, smooth, their posterior edges denticulate; about 44 scales 

 around middle of body; about 48 scales from occiput to a point directly 

 above the vent; about 11 dorsal scales the equivalent of the distance 

 from snout to occiput; nuchal scales small, those on the sides of the 

 neck like the dorsals, those behind the ear keeled and imbricate, not 

 granular. Shoulder folds present; no lateral folds. The adpressed 

 hind limb reaches almost to the posterior corner of the eye. Digits 

 compressed; the fourth toe with 23 tricarinate lamellae. A distinct 

 crest beginning on the occiput, moderately developed on the back 

 and becoming a little higher on the proximal part of the tail ; the other 

 caudal scales mucronate and keeled above, smooth below; no verticils. 

 The keels of the lateral and dorsal scales are directed upwards and 

 backwards, so that the scale rows converge on the posterior part of 

 the back; the convergence is less pronounced anteriorly. Tail some- 

 what compressed proximally, so that its section would appear squarish. 

 A pair of enlarged postanals in the male. 



"Dimensions. — Snout to vent, 68 mm.; head to posterior ear, 17 

 mm.; tail (reproduced), 82 mm.; foreleg, 25 mm.; hindleg, 40 mm.; 

 width of head, 14 mm. 



"Color in alcohol. — Body color dull sage green above, with a wide 

 light dorsolateral stripe beginning behind the eye, running above the ear 

 and continuing along the sides onto the tail; this light stripe bordered 

 above and below by wide sepia stripes; scarcely any traces of dorsal 

 crossbars in the adult male; throat indigo blue with a series of 

 about four regular transverse rows of spots running across it, the 

 posterior ones continued as stripes onto the labials and nearly to the 

 upper part of the head; mental and rostral shields with pale buff 

 immaculate borders; chest and belly wax yellow, the under surfaces 

 of fore and hind legs and tail deepening to gamboge yellow; sides of 

 body dull indigo with some brighter china-blue scales edged with 

 sepia; no spots or bars on posterior part of body or tail or on upper
