Adults average 6.5 to 8.5 cm (2.6 to 3.3 in) snout-to-vent length (SVL).

The record size is a male 9.0 cm (3.5 in) SVL.

Dorsally, it is olive-colored, with four or five dark undulating crossbands.

[4] The preferred habitat of C. fitzsimonsi is rocky outcrops in arid savanna or in semidesert,[4] at altitudes of 20–1,000 m (66–3,281 ft).
