DiagnosisDescription. Garman did not describe this lizard, but merely pointed out some of the differences between it and sagrei D. & B., omitting the important character of the nearly smooth ventral scales, compared to those of sagrei which are heavily keeled. It seems well to describe the species in detail: Top of head covered by large, elongated faintly keeled scales; supraorbital semicircles pronounced, not sharply keeled, separated by one row of small scales; supraocular disc of about eight faintly keeled scales, separated from the supraorbital semicircles by one or two rows of smooth granules; canthus rostralis sharp, of three long scales; superciliary ridge of three long sharp scales; loreals in five rows; subocular semicircles of five keeled scales; temporal area of granules outlined by larger scales: occipital area concave; occipital plate large and smooth, larger than ear-opening, surrounded by large faint ly keeled scales; six or seven labials, fifth or sixth under eye; five or six large and a small lower labial; rostral low and wide; mental creased to tip, followed by two large plates bordering first labial and separated mesially by three or four rows of granules; lower labials bordered by five rows of elongated, keeled scales; throat covered with hexagonal granules, longer near chin, triangular and faintly keeled near fan; fan small, sparsely covered with triangular scales; sides of body covered with fine granules, about seven median rows enlarged and faintly keeled; scales of chest and venter larger, faintly keeled; front aspect of limbs covered with keeled scales larger than on belly, hind aspect granular; top and bottom of tail with large, pointed, sharp-keeled scales, smaller on sides, in whorls of four on top and six to eight on sides; postanals slightly enlarged in males; 19 to 21 lamellae under fourth toe: 52 to 58 dorsal and 38 to 41 ventral scales in distance snout to ear. (Grant 1941)

Dimensions. Large males: Snout to vent, 57 mm.; tail, 100 mm. Females: Snout to vent, 37 mm.; tail, 72 mm. (Grant 1941)

Proportions. As in sagrei and similar to small Anoles in general. (Grant 1941)

Color pattern. Male: Fan dirty yellow sparsely covered with scales which are largely cream-colored or interspersed with black; fan never shows any shade of red or brown; predominant color is gray, but the lizard can change to coffee-color or black; in transition many light marks appear in the pattern; chin longitudinally marked with dusky. Female: Without fan; does not turn black; usually shows a light dorsal stripe edged with dark brown or bears cross bars; usually a plain gray, lighter underneath. (Grant 1941)

Sexual dimorphism. Male one-third longer than female; has slightly enlarged postanals and a fan. (Grant 1941) 
CommentSpecies group: Norops sagrei species group (fide NICHOLSON et al. 2012).
