Emma Gray's forest lizard (Calotes emma) is an agamid lizard found in China, South Asia and Southeast Asia.
The specific name, emma, is in honor of English conchologist Maria Emma Gray, the wife of John Edward Gray, the describer of this species.

Dorsal crest well developed on the neck and on the anterior part of the trunk, gradually disappearing behind. A transverse fold in front of each shoulder; gular sac but little developed. Tail compressed. About fifty-one series of scales round the middle of the trunk.
Color Pattern: Brownish olive, with brown bands across the back, which arc lighter in the middle and interrupted by a white band running along each side of the back; eyelids with short, radiating brown streaks; a brown band from behind the eye to above the tympanum; fold before the shoulder black, with an irregular white margin; legs and tail with indistinct dark cross bands.
