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 b'ght yellowish-green. 



(ii.) Bright grass-green. 



(iii.) 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
