Flaviceps (Reinhardt). — This is the only one of the group with 13 

 scale rows. It is really a Malayan snake extending into our Territory 

 only in Tenasserim, which is a part of the Malayan Sub-region. 



Bungaroides (Cantor). — This shares with flaviceps and sindanus, 

 the peculiarity of having some of the terminal subcaudals divided. 

 It differs from both in having 15 scale rows. It is a rare snake 

 known only from the Eastern Himalayas in the vicinity of Darjee- 

 ling, the Khasi Hills in Assam and North Cachar.*
