DENDROPHIS. 
They may be considered as Colubri of an elongated and 
slender form. Their trunk is compressed ; the abdomen, 
and even the tail, are ordinarily angular, and clothed with 
very broad plates ; the scales, disposed in very oblique rows, 
have a lanceolate or even a linear shape on the neck ; the 
tail is very slender ; the head presents almost the same 
structure as that of the genera Coluber and Herpetodryas, 
but its form is much longer ; the eye is large, the pupil 
orbicular. This genus is adorned with very vivid colours, 
and inhabits the warm regions of both worlds ; it exists 
not in Europe, and is very rare in Australia.

Very subject to variation. Scales smooth ; a range of 
dorsal scales, very broad in the form of plates. Angles 
of the abdomen salient and sloping. Above brown-bronze ; 
sides of the abdomen marked by a yellow ray, bordered 
with black ; below whitish ; on the sides of the neck there 
are often oblique black and blue spots. S. 175 + 128.
