104 CYSTIGNATHUS ORNATUS. 
small, very dark coloured, and placed in a dark vitta, or blotch, which extends 
from behind the orbit to within a short distance of the shoulder. 
The body is short, of a delicate dove-colour above, with two or more oblong 
spots of dark brown, margined with yellow, on each side of the vertebral line; 
below these, and on each flank, are three smaller spots, likewise margined with 
bright yellow, the anterior one being the largest; these, with a smaller one above 
the vent, form a triangle on each flank; several bright yellow spots, also disposed 
in a triangular form, with the apices directed forwards, are concealed by the 
thighs. The inferior surface of this animal is silver-white, and except on the 
throat, every where granulated; about the throat are a few indistinct points of 
black; the anterior and middle parts of the abdomen are white, with a slight 
tinge; the posterior third approaches to flesh-colour. 
The anterior extremities are short, dove-coloured above, with a few distinct 
dark bands placed transversely on the fore-arm, and a black spot at the elbow; a 
black line runs from the inferior and upper part of the shoulder towards the lower 
jaw; the fingers are four in number, distinct, nearly equal, and the thumb seems 
less inclined to turn backwards than usual. ‘The posterior extremities are also 
rather short, dove-coloured above, with transverse bands of dark brown: on the 
anterior part of the thigh are several small yellow spots; on the posterior surface 
these spots are so numerous and so closely approximated, as to resemble at first 
view a yellow waving line. The whole under surface of the thighs is flesh- 
coloured and granulated; the inferior surface of the legs is also flesh-coloured, 
with a few yellow dots; the toes are five in number, not palmated, the two 
outer ones only are united at the base.
