Eye rather large, its diameter a little exceeding its distance from 

 the nostril ; rostral just visible from above ; suture between the

 long as its distance from the end of snout or a little longer, shorter 

 than the parietals ; loreal as long as deep or deeper than long ; one 

 prseocular; three postoculars ; temporals 2 -f 2 or 2 + 3; upper labials 

 8 normally, third, fourth, and fifth entering the eye ; 5 lower labials

Hob. From Sikhim, Assam, Burma, and Southern China to the 

 Malay Peninsula and Java. This is a common species, chiefly 

 inhabiting hilly country, though rarely found above 3000 or 4000 

 feet.

Agrees very closely in structure and in colour with T. subminiatus, 

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

 fourth and fifth) entering the eye, and by the presence of a yellow 

 or orange collar 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. 



Hob. Himalayas (Nepal and Sikhim) and Assam Hills. Dr. 

 Stoliczka observes that this species is not common in Sikhim and 

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

 above 5000 feet.
