Eight specimens of this Snake, collected in five weeks, would seem 

 to indicate that the species is not uncommon at Darjeeling. The 

 specimens form two varieties ; and the colouring is wonderfully 

 uniform in all. The very ) r oung specimen has a broad intensely 

 black collar ; and the rest of the upper surface is pale greyish brown. 

 The collar is perceptible in all the adults.

This is not uncommon at Darjeeling at elevations between 3000

The first specimen has the elongated loreal divided into two on 

 each side. The colour is uniform metallic black, with an iridescent 

 lustre. The third specimen has the centre of the ventrals of a 

 pinkish brown, paling in their posterior margins to a lighter pink. 

 The angles, however, of all of these shields are deep metallic black, 

 and the pinkish centres are more or less speckled with the same 

 colour.
