This Snake has not been previously known to occur as far north- 

 wards as the central hilly region of Nepal. It must be a beautiful 

 little harmless creature when alive, the back being cheslnut-brown 

 between the two median black stripes, and the sides blue ; a bright 

 purple band, entirely lost in preserved specimens, runs along the 

 middle of the abdomen between two lateral series of black spots.
