Localities. Found in Penang (Cantor and others), Province 

 Wellesley (two specimens in Mr. van Sommeren's collection), 

 Perak (several specimens from Taiping and Kuala Kangsa, in the 

 Taiping Museum), and Singapore (Cantor and Hanitsch ). 



It does not seem to have been pi'eviously recorded from Siam, 

 where I obtained four specimens from Bangkok and one from 

 Ayuthia. 



Habits. Like most species of Coluber, this is a fierce snake and 

 will bite one vigorously ; the neck is apparently dilatable. 



Colour (in life). Above yellowish brown, with three black lines 

 along each side of the anterior part of the body : these may be more 

 or less broken up into a series of elongated spots ; usually the upper 

 line is broad and conspicuous, and the low est narrow and indistinct ; 

 a well-marked black line across the occiput; three black lines 

 radiating from the eye. Lower parts uniform yellow, or lemon- 

 yellow anteriorly and yellow with pink shades posterioi-ly (after 

 death, in specimens placed in spirits, dark purplish speckles mav 

 appear). In young specimens the anterior half of the body may 

 be indistinctly reticulated with white. Iris bright golden (" bright 

 gamboge, with a concentric black ring " — Cantor). 



Size. The largest Bangkok specimen was 1696 mm. in total 

 length. 



Hub. Eastern Himalayas, Bengal, Assam, Burma, South China.
