m the hills and valleys, preying upon small birds, arborial lizards, 

 frogs, and in early age upon insects. It may readily be distinguished 

 from Dryinus nasutns, (Lacep.) (Merrem, not Bell ; — Russell, I. PI. 

 12, 13) by two, sometimes 3 frenals on each side. The trunk is 

 covered by 15 longitudinal series of smooth rhomboidal scales with 

 rounded points, imbricate so as to appear linear ; those of the tail are 

 all broad rhombic. The anterior upper maxillary teeth gradually in- 

 crease towards the sixth, which is the longest, and enclosed in a point- 

 ed fold of gingiva. The following teeth, commencing at a short 

 interval, are short, but the last is very long with a furrow on the con- 

 vex edge. The inferior maxillary teeth also increase in length towards 

 the sixth, the longest, and are protected by a broad triangular scab- 

 bard, containing several additional loose teeth ; the rest are uniformly 

 small, commencing at a short interval from the sixth. The palatal 

 are uniformly very short. The largest individual of a great number 



measured :

The Varieties, of which B. and C. were from the hills of Pinang, are 

 not numerous, and of a comparatively small size. The very young 

 ones are as gentle as those of a more advanced age are ferocious. 

 Their power of expanding the anterior part of the body and their 

 mode of attack, have been noted under Herpetodryas oxycephaly,*.
