Head above brown, paler on the muzzle ; three longitudinal white 

 bands along the body, — one along the middle, originating between the eyes, 

 and two along the sides, beginning on the supraciliary edges ;-^they are 

 separated, above, by two somewhat broader brown bands, each being lighter 

 coloured along the centre, and bounded at the sides by a similar brown band 

 which is, however, darkest along the centre. The median dorsal white band 

 becomes obsolete at the root of the tail, the two lateral ones continue on it, 

 and unite when approaching the tip. Labials and sides of head brownish, 

 spotted with white. Lower portion of the sides and the entire lower surface 

 livid carneous, most distinctly so, and tinged with bright orange, on the lower 

 belly and on the tail/ which is also on the upper side carneous, with a few 

 white dots at the side of the base, and irregularly marked with pale brown 

 on the lower sm-face. Limbs, above, with very close longitudinal brown lines, 

 toes all distinctly powdered with pure white. 



Total length four inches, the head and body being 1'8, the length of 

 the fore limb is equal to the distance between the shoulder and the angle 

 of the mouth, or one-third of the distance between the axil and the groin ; 

 the length of the hind limb is one-half of the same distance. 



Hah. — South Andaman. The single specimen was obtained on a sandy 

 beach in Macpherson's Straits. 



TiARis Htjmei, n. sp. 



A larger species than T. subcristata^ and -like this one with the crest 

 interrupted above the shoulders, but the crest itself is very much more deve- 

 loped. The nuchal part is considerably higher than the dorsal one, on its 

 convex edge it is composed of 13-15 lobes ; the dorsal portion continues on 

 to the tail, disappearing after about one-fourth of its length. None of the 

 scales are at the lateral bases of the crest particularly enlarged. All scales 

 on the body are distinctly and sharply keeled. 



Head shelving and concave above; snout with a few enlarged scales 

 along the centre ; supraciliary edge sharp, its posterior end is separated by 

 a short groove from a small tubercle following it. Two groups of enlarged 

 conical scales on the upper side of the occiput ; several (3-4) enlarged 

 scales on the side of the head above the tympanum which is hardened near 

 the centre, and about as large as the eye. Below the tympanum no scales 

 are enlarged. Eight or nine upper labials and seven or eight lower labials ; 

 the scales adjoining the former are enlarged, and there is also a conspi- 

 cuous row of slightly enlarged scales below the eye. A row of enlarged scales 

 is separated from the lower labials by one of small scales. Scales on the side 

 of the neck and body very small, arranged in somewhat irregular transverse 

 series, with scattered larger ones intermixed ; on the tail they gradually 

 increase in size, but within a short distance of its base still have some
