Stenocercus rhodomelas, syntype, BM , male. caudals keeled, imbricate, mucronate (anterior ventrals smooth, imbricate); vertebral crest extending more than half the length of the tail; tail length 64% of total length; posthumeral pocket Type 4; postfemoral pocket Type 5. Data on syntype BM : Male (Fig. 18); SVL = 82 mm; TL = 146 mm; HW = mm; HL = mm; HH = mm; SM = 50; VS = 51; PS = 56; SS = 5; IS = 2; GS = 19;SF=18;ST = 29. Variation.—Measurements and scutellation of Stenocercus rhodomelas in Table 1. Head (Fig. 17B and D) wider than high (HH/HW = , x= ± , n = 29); 2-3 postrostrals, wider than long; if 3 postrostrals, middle one as wide as long; 2-A internasals, usually 2 (67% of specimens); most anterior canthals separated from na- sals by 2 tiny scales (29% of specimens); parietal eye vis- ible in 67% of specimens; apical pits of gulars and ventrals most evident in adult males; body normally wider than high (BH/BW = , x= + , n = 16); verte- bral crest most conspicuous in adult males; 14-21 lamel- lae on Finger FV; 22-29 lamellae on Toe FV; vertebral crest extending more than half length of tail in males, less than half length in females; tail length 57-66% of total length. Sexual variation in scutellation and measurements of S. rhodomelas is presented in Table 11. Color in life: Dorsum and flanks of an adult male (QCAZ 3663) dark brown with several pink, cream, or black scales distributed irregularly; vertebral crest dark brown with a few yellow scales, some with black marks; dorsal black V-shaped mark between shoulders with vertex pos- teriorly; three faint V-shaped marks behind the latter; small black mark anterior to each
