2) rows of loreals; scales between supraorbitals 0-2 (mode 1); 1-2 (mode 1) scales between interparietal and supraorbital semicircles; suboculars in contact with supralabials; 2 - 3 (mode 3) scales between nasal and rostral; 2 - 5 granular postmentals; 4-8 postrostrals; middorsal scales small, smooth, subequal, with a longitudinal series of isolated, spine-like scales separated by about 6-8 small, flat scales; ventrals smooth, distinctly larger than dorsals, juxtaposed, in often poorly defined rows; dewlap in both sexes, large, inset; limbs short, scales smooth, including supradigital scales; tail round, nonverticillate, with a continuation of evenly spaced middorsal spines, dorsal caudal scales larger than ventrals, smooth to weakly unicarinate, ventral caudal scales much larger, strongly unicarinate. Dorsum almost white to tan (when sleeping) to dark brown (in weak metachrosis) when active, or with lichenate pattern involving tan and brown with a row of tiny, dark brown dots on middorsal line (= median dorsal spinose scales); a small black to dark brown nuchal dot and a broad, dark sacral U (in pale phase); 2 radiating black lines from eye onto temporal region; a ventral radiating line from eye, forming 1 of a maximum series of 5 incomplete transverse, dark lines across throat; dewlap pale peach in males, brown with cream border in females, scales large and arranged in rows, marginal dewlap scales crowded and about same size as throat scales adjacent to dewlap; venter white (Schwartz & Henderson 1991: 340).
