Malayan Peninsula and Islands. 37 



The only individual examined, was captured on a botanical excur- 

 sion by Sir William Norris on the Pinang Hills, on the bank of 

 a mountain stream, at an elevation of about 2,000 feet. It appeared 

 slow in its movements, of general sluggish habits, showed no power of 

 changing colours, and in confinement it refused insects, vegetable food, 

 as well as water. After having been preserved in rectified spirits of 

 wine for upwards of three years, the specimen has retained the original 

 brown and white colours and the Indian red spot ; but the yellow, light- 

 green and light-blue have changed to whitish, and the dark blue marks 

 to blackish. Although the colours in this state do uot agree with those 

 given by Mr. Gray, apparently though not stated, taken from a pre- 

 served specimen, the peculiar distribution of the markings correspond, 

 and induce me'to believe in the identity of the animals.
