C o l o u r , &c .— The ground colour of the upper and lateral parts of the
head, of the back, and of the sides intermediate between brownish purple-
red and yellowish brown ; the top of the head variegated with two longitudinal
liver-brown stripes united behind on the hindhead to a large blotch of the
same colour, from which proceeds a short similar coloured stripe along each
side of the neck. Back and sides marked with four rows of liver-brown
spots, those of the two middle rows crescent-shaped and distinctly edged
with reddish white, those of the lateral rows smaller, somewhat quadrangular,
and also edged with reddish white, the edgings of the upper and lower sides
of these spots are connected by stripes of the same colour, and so form two
light coloured and waved lines on each side of the body. The colour of the
sides beneath the lowermost line pale yellowish brown freckled with small
liver-brown spots. Abdominal plates rusty straw-yellow, partially crossed
by closely set blackish green bars, and the plates at each extremity marked
with a liver-brown spot; subcaudal scales, each marked with a large blackish
green spot. Each side of the head with an oblique white stripe which commences
at the hinder angle of the eye, and terminates on the upper lip, the
latter as also the lower lip white, spotted with liver-brown. In many specimens
the white stripe which proceeds from the eye is margined behind with
one of liver-brown, and also in many there is a clear white blotch near to the
nose immediately over the upper lip. Each of the dark stripes of the head
is edged externally with a white stripe.
