On two Specimens of the Chameleo cristatus. 229 
spots ; below, and inside the legs, the colour is lighter or 
dirty white, which is also more abundant over the base of 
tail, and back parts of the body. 
In the first specimen, the crest is spotted all over with 
dark-grey or brown ; in the second this is less distinct, but a 
! darker band runs along its base. The scales of the body are 
small, with scattered larger ones over the body. The scales 
of the legs are small, and equal in size. 
In both specimens the top of the head is spotted with 
black and dirty white ; and in the first, the top of occipital 
crest is blunt ; there are two small oval-shaped spots of a 
hght colour, with a darker border and bar between them, 
side by side on the front of the muzzle, above nostrils. In 
the second specimen these spots are dark-coloured and their 
edges lighter, and its occipital crest is pointed above ; the 
base of the tail is the thickest in this specimen, the enlarge- 
ment gradually tapering backwards, and extends from the 
anus along the tail for about f of an inch ; the first being 
probably a male, and the second a female. The tail is also 
j rather longer ; in both specimens the tail is comparatively 
I short, and tapers rapidly to a point. The chin and neck are 
destitute of any crest ; a faint crest, however, consisting of 
slightly raised and pointed tubercles or scales, commences 
below and between the anterior extremities, and terminates 
I at the anal opening.
