above the commissure of the jaws; eight or nine supralabials to a 

 point below the center of the eye, the last ones hornlike, the anterior 

 ones quite smooth; tympanum elliptical, erect, large; eight lower 

 labials to the center of the eye, the posterior ones bluntly ridged and 

 swollen; a series of enlarged malar scales, the posterior ones swollen 

 and heavily ridged and separated from the lower labials by one (ante- 

 riorly) to five (posteriorly) rows of scales mostly of very small size; 

 dorsal and ventral scales rhomboidal, obliquely keeled, the keels 

 pointing toward the median line; dorsal scales very small, about 60 

 scales measured posteriorly from the axilla contained in the distance 

 from end of snout to anterior edge of tympanum; ventral scales 

 slightly larger than dorsals but less heavily keeled; from the occiput 

 along the median line of the body and tail a series of enlarged scales

forming a high serrated crest, which is greatly reduced on the neck 

 and on the rump; scales of the caudal crest somewhat larger and 

 heavier than the others; about 21 scales in the nuchal and 48 in the 

 dorsal portions of the crest; throat covered with scales smaller and 

 smoother than the ventrals; sides of neck with numerous folds; a 

 large longitudinal gular fold, with a smaller transverse fold behind it; 

 a rather weakly developed lateral fold ; upper surfaces of forelimbs 

 and hindlimbs with slightly imbricate keeled scales much larger than 

 the dorsals, on the lower arm about three and on the tibia about two 

 scales to the height of the rostral; no highly spinose tibial scales; a 

 double series of femoral pores, about 19 in the upper row; inner side 

 of second toe with one comb, of third toe with two combs, the proximal 

 the larger; a tendency to form a comb on the three distal joints of the 

 fourth toe; nails long, sharp; tail covered with rectangular keeled
