Colour. — The upper surface of the head greenish-brown, or pale orange- 
coloured brown ; the back and sides intermediate between pale reddish- 
orange and sienna-yellow, — in some specimens almost pure sienna-yellow ; 
the upper lip and the under parts of the body and tail intermediate between 
sienna and cream-yellow ; the abdominal plates variegated with small black- 
ish-green blotches along their hinder edge, especially towards each extremity ; 
the subcaudal scales are also marked with like blotches, which, as individuals 
advance in age, become fainter, and are at length only indistinctly visible 
towards the head. On the back and sides the variegations are numerous 
and strongly marked, consisting, on the first half of the body, usually of 
three rows of greyish-black spots, and on the last half and tail, of three 
more or less regularly defined greyish-black stripes. The spots are of con- 
siderable size, irregular in shape, the dorsal ones the largest, each of them is 
edged with a ring of liver-brown ; the spots of the middle row, especially to- 
wards the head, frequently coalesce and form a short irregular band. The 
waved line which is often observed on the back posteriorly, is commonly pro- 
longed for some distance on the upper surface of the tail ; and the lateral 
* Ch. Gen. Head quadraugular ; nose pointed. Hinder tooth of maxillas long, curved backwards, 
pointed, and grooved from base to apex ; other teeth small. Nostrils formed by three scales. Pupil cir- 
cular. Frenal plate one ; postocular plates two. Scales of body rather long, narrow, ovate, imbricate, 
and arranged in oblique transverse rows. Plates of abdomen long. Body subcylindrical, below slightly 
flattened. Tail cylindrical and pointed. 
I have removed this snake from Ccelopeltis of Wagler, as it does not exhibit the hollow in the scales, 
which is characteristic of his genus.
