a few white spots on the lower parts, becoming indistinct towards the

 dark brown ; labial shields yellow, edged with black ; beneath yellowish 

 white, scutella edged with brown. Iris gamboge with a black concen- 

 tric ring ; pupil round, tongue black ; central series of dorsal scales 

 hexagonal.

The head is distinct, elongated, with the muzzle broad, truncated, 

 covered above with the normal number of shields, in form resembling 

 those of Col. korros. The eyes are large, prominent, with two pree- 

 orbitals, of which the superior is the larger, the inferior is wedged in 

 between the 3rd, 4th and 5th upper labials. In addition to two post- 

 orbitals, there is an elongated crescent-shaped infra-orbital, resting on 

 the 6th and 7th upper labials. The latter are 8 on each side, of which 

 the 5th, broad hexagonal, borders the orbit ; the following are elongated, 

 gradually increasing in size. The lower labials, 9 on each side, lie on 

 the chin in contact with two pairs of elongated shields. The nostrils 

 are rather large, orbicular, opening near the margin of the anterior 

 frontals. The frenal is small, obliquely situated between the surround- 

 ing shields. The temples are covered by two pairs of elongated shields. 

 The gape is wide, the teeth minute, of equal length. The trunk is 

 slender, much compressed with 1 7 longitudinal series of smooth, rhom- 

 bic, sub-imbricate scales, of which the central series is hexagonal. The 

 abdomen narrow, arched. The tail is very slender elongated, tapering 

 to a sharp point. 



A solitary individual, discovered by Sir William Norris on the Great 

 Hill of Pinang, was of the following dimensions :

Ditto ditto tail, 4f 



1 ft. 3| inch. 



Circumference of the neck f , of the trunk 1 inch., of the root of the 

 tail -f. In fierceness it resembled the preceding species.
