the fifth and sixth upper labials. The eye is sunk, excessively minute, 

 surrounded by two small post-orbitals ; beneath by the third and fourth 

 upper labials, and by a single narrow triangular prae-orbital. The 

 latter is placed obliquely, so that the downwards pointed apex meets 

 the linear posterior part of the nasal, or as it is considered by some, 

 the frenal. The nostrils are comparatively large. The upper labials 

 number six on each side : the two posterior are the largest. The chin 

 is covered by two pairs of elongated narrow shields, externally bordered 

 by the third and fourth, the largest of the six inferior labials. The 

 gular scales are more numerous than those of E. intestinalis. The 

 neck is covered by 15, the trunk by 13 longitudinal series of smooth 

 rhombic scales with rounded points. This species is of no uncommon 

 occurrence in the hills of Pinang. The largest individual was of the 

 following dimensions : 



Length of the head, ft. Of inch. 



Ditto ditto trunk, 2 If 



Ditto ditto tail, If 



2 ft. 3f inch. 

 Circumference of the trunk, 1 inch.
