On two Specimens of the Chanieleo 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 

 light 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 

 rather longer ; in both specimens the tail is comparatively 

 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 

 at the anal opening.
