 This species is very numerous in the Malayan countries both in the 

 vallies and on the hills. It moves and leaps with great quickness among 

 the branches of trees. The most striking feature is the great power of 

 suddenly changing its colours. The Malayan denomination of this 

 species is " Griming" which in Marsden's Dictionary is translated " a 

 species of lizard, which changes its colour as it is affected by fear or 

 anger ; the cameleon." No cameleon however appears to inhabit the 

 Malayan countries, but the present lizard passes under that name among 

 the European inhabitants. One of the largest males was of the follow- 

 ing dimensions :

 death it sometimes acquires this colour from the effects of spirits of wine, to which cir- 

 cumstance must be attributed the denomination of " Blue Calotes," Gray, in Griffith's 

 edition of Cuvier. Vol. 9, p. 55.
