The Malays of Biserat call this snake by the same name as 

 DipsadomorpTius dendrophilus (i. e., " Ular katam tebu). They 

 appear, however, to distinguish between the two to some extent, 

 regarding DijJsadomorpJms as non-poisonous, or at any rate not so 

 poisonous as the Bungarus.

 snake. A young specimen from Biserat belonged to var. B of the

 has no darker markings.
