Description and variation.—Measurements and scutellation of Stenocercus ornatus in Table 1. Head (Fig. 17A and C) wider than high (HH/HW = , x = ± , n = 40); occipitals, parietals, interparietal, and postparietals small, keeled, slightly imbricate; 2-4 postrostrals (wider than long when there are 2 or 3 but as wide as long when there are 4); 2-A internasals, usually 4 (64% of specimens); 2 canthals, most anterior one in con- tact with nasal or separated from it by 2 tiny scales; supraoculars keeled; enlarged supraoculars absent; lateral temporals slightly keeled, imbricate; parietal eye visible in 82% of specimens; gulars imbricate and smooth, each bearing apical pit; mental in contact with first pair of infralabials and first pair of postmentals; postmentals in contact medially or sometimes separated by tiny scale (14% of specimens). Body normally wider than high (BH/BW = , x= + , n = 34); dorsal scales of neck and body and lateral scales of body keeled, imbricate, mucronate; lateral scales of neck keeled, imbricate; vertebrals large, forming prominent, serrate vertebral crest; slight dorsolateral crest on each side of neck (extending behind shoulder in some specimens); ventrals imbricate, smooth, or slightly keeled (43% of the specimens); preauricular fringe near
