Of this remarkable-looking lizard I obtained two specimens 

 during March and April, 1898, in Penang, one in a valley and one 

 at 2200 feet elevation in the hills. Cantor writes of it — " At 

 Pinang this species appears to be very local, and not numerous ; 

 two individuals were obtained from spice plantations in the valley. 

 They were very active and fierce, possessed in a slight degree the 

 power of changing the ground-colour to a light hue, and in captivity 

 refused food and water." One specimen I kept alive for a short 

 time, however, seemed to have considerable power of changing its 

 colours. The male when angry distends its gular pouch. 



In the British Museum are specimens from Gen. Hardwicke's 

 collection labelled Singapore ; but one cannot help feehng doubtful 

 of some oF the localities of Hardwicke's specimens, and it seems 

 strange that in an island so well known as Singapore, and constantly 

 visited by collectors, this lizard should not have been again secured. 



M. Mouhot obtained A. armata at Chantaboon, and I have seen 

 a specimen that was shot there in July 1896. 



Colour (in life). Upper surfaces — head chestnut, remainder 

 blackish green, a transverse black band in the interval between the 

 cervical and dorsal crests, continued forward over the shoulders ;

 orange-colour. L'is brown with a narrow golden ring.
