Gonyocephalus grandis, Boul. Cat. Liz. i. p. 298. 
Cantor obtained one specimen from the hills of Penang, at an 
elevation of 2000 feet. 
Hab. Burma, Malay Peninsula, Sumatra, and Borneo.

Cantor says that “two individuals were obtained from spice 
plantations in the valley” at Penang, and there are specimens in 
the British Museum from Singapore from Gen. Hardwicke’s 
collection. 
Hab. Tenasserim, Siam, Cochinchina, and Malay Peninsula. 
81. CALOTES CRISTATELLUS, Kuhl. 
Bronchocela cristatella, Cantor, p. 30. 
Calotes cristatellus, Boul. Cat. Liz. i. p. 316. 
Cantor says, “ This species is very numerous in the Malayan 
countries both in the valleys and on the hills, Malayan Peninsula, 
Pinang, Singapore.” Stoliczka obtained specimens from Penang 
and Province Wellesley, and from Singapore (Bronchocela moluc- 
cana). Dr. Blanford mentions it in the collection he got from 
Dr. Dennys from Singapore. I only obtained one specimen in 
Penang, but at Tanglin, Singapore, found this species very nume- 
rous; the largest male was 481 mm. in total length (H.B. 113, 
tail 368), the females seem to grow to nearly the same size. In 
one specimen caught at Tanglin, the tail at 113 mm. from the 
anus bifurcated, one branch being 109 mm. long from fork to tip, 
the other 197 mm. 
As Cantor remarks about this Lizard, ‘“ the most striking feature 
is the great power of suddenly changing its colours.” Both this 
species and Calotes versicolor are commonly called Chameleons by 
the English in the Straits Settlements. Among the Klings in 
Singapore there is a belief that these Lizards have twelve different 
colours, which they change during the day, a colour for every 
hour. 
The colours I have noticed of this species are :— 
(i.) Very light yellowish-green. 
(ii.) Bright grass-green. 
(ui.) Bright green as above with large dark-brown patches. 
(iv.) Dark green, almost black. 
(v.) Dark brown, almost black. 
(vi.) Dull grey-brown. 
The brighter green colours are generally uniform ; but the other
