 from which it is distinguished by having two labials only (normally

 or orange coUar separating the head from the black nuchal spot. 

 Sometimes a single anterior temporal, more frequently two. Ven- 

 trals 158-170 ; subcaudals 79-90. 



Total length 2 feet 9 inches ; tail 8 inches.

 that it is mostly confined to the lower valleys, rarely going up to or 

 above 5000 feet.
