 Localities, Of this species, already recorded from Penang and 

 Singapore, I obtained four specimens on Penang Hill, at elevations 

 of about 2200 feet, and one at the mouth of the Batu Caves, near 

 Kuala Lumpor, Selungor, 



Habits. Two were found under a water-butt near a house ; when 

 disturbed they were fierce, striking and threatening with wide- 

 opened mouth. 



Colour (in life). These snakes are highly iridescent, and the line 

 of demarcation between the dark upper and light lower parts is 

 shai-ply defined : upper parts rich dark brown, purplish blue, or 

 blackish ; lower parts uniform white, buff, or very pale purplish 

 blue, with a more or less indistinct zigzag median dark line under 

 the tail. Head and neck bright lemon- or sulphur-yellow ; on the 

 top of the head there may be a symmetrical chestnut-coloured
