both extremities, covered with 15 longitudinal series of smooth, rhom- 

 bic, imbricate scales. The abdomen is arched, the short tail tapering 

 to a blunt point. This species approaches to Calamaria alba (Linne), 

 (C. brachyorrhos, Schlegel), but differs by its elongated shape of the 

 shields of the head, and its larger eyes. A single individual, captured 

 by W. T. Lewis, Esq., on the Great Hill of Pinang, was of the follow- 

 ing dimensions :

But for the diminutive size, and the reduced shields of the head and 

 throat, this species might be taken for a Coronella. The head is but 

 little distinct, depressed, ovate, covered by the normal number of 

 shields. The anterior frontals are very small, pentagonal ; the frenal 

 short rectangular. The nostrils are rather large, piercing the middle 

 of the nasal. The eyes are large, prominent with one prse-orbital, two 

 post-orbitals ; the upper jaw, but slighly longer than the lovver, has on 

 each side 6 labials, the lower 7, enclosing two pairs of small mentals. 

 The temples are covered by three shields. The trunk, with 17 longi- 

 tudinal series of smooth, rhomboidal imbricate scales, is slightly thick-
