I have obtained this elegant Tree-Snake from Alor Star, Kedah, 

 from Penang (sea-level to 2500 feet), from Johore Bahru, and from 

 Singapore ; and seen specimens from Selangor and Pahang. 



Habits. Cantor says of this species, "The very young ones are as 

 gentle as those of a more advanced age are ferocious." However, 

 a specimen 1314 mm. in length (that is to say an average-sized 

 adult) we kept in captivity for three months was always most 

 gentle and never attempted to escape, living at liberty in the 

 drawing-room, usually among the leaves of a small palm which 

 stood on a table, but sometimes going to the window to bask in the 

 sun ; and larger specimens even when first caught were perfectly 

 gentle and tame. 



Hab. Eastern Himalayas, Assam, Burma, Cambodia, Lower Siara, 

 Malay Peninsula, Sumatra, Nias, Sipora (Mentawei Islands), Java, 

 Lombok, Grreat Natuna, Borneo (I obtained a specimen at Kudat), 

 Celebes, Ternate, Philippines.

Localities. Var, A : Cantor and Stoliczka record it from Penang, 

 where I obtained two specimens at sea-level and saw a third in 

 Mr. Yan Sommeren's collection caught on the hill at an elevation 

 of 2500 feet. It is also known from Kulim in Kedah (S. S. P.), 

 Jelebu (Hanitscb), Kuala Lumpor (Van Sommeren coll.), and
