Sexual variation in scutellation and measurements of S. humeralis is presented in Table 7. Color in life: Dorsum in males (Fig. 5D) yellow-green with a few transverse rows of yellow spots extending onto flanks; black dorsal and lateral collar extending to inser- tion of forearm on each side; venter pale yellow (Thomas H. Fritts, field notes, 28 June 1970). Dorsum and flanks in females yellowish green; scattered black flecks on dorsum; chin and gular region pale yellowish green; ventral sur- face of body and limbs pale yellow; subcaudal region beige (Thomas H. Fritts, field notes, 26 and 27 June 1970). Dor- sum in juveniles yellowish beige or pale brown; transverse black bars on vertebral line; black flecks and blotches might be present on dorsum; chin and venter yellow (Thomas H. Fritts, field notes, 28 June 1970). Color in preservative: Dorsum with several dark short transverse bars on vertebral line; black transverse stripe across dorsum between shoulders; ground color of head, body and tail gray; ventral surfaces cream, reddish cream, or pale gray. Natural history.—One female (EPN 5829) collected in December 1968 contained four oviductal eggs, two in each oviduct. Mean size of these eggs is mm x mm. Mean volume of the eggs is mml The smallest indi- vidual (FHGO 1495), collected on 14 October 1996, has a total length of 118 mm (SVL = 40 mm, TL = 78 mm). Distribution and ecology.—Stenocerciis humeralis oc- curs at elevations of 2000-3000 m in the Loja Basin in south- ern
