3. Acanthosaura capra.
The upper orbital edge not serrated, terminating posteriorly in a long moveable horn: no spine above the tympanum or on the side of the neck: nuchal crest high, not continuous with the dorsal crest, which is rather elevated anteriorly: crown and cheek without markings.
The tympanum is distinct: no femoral or præanal pores: back and sides covered with small smooth scales, which become gradually larger and more distinctly keeled towards the belly: no large scales intermixed with the small ones; only a few appear to be a little larger than the rest: tail slightly compressed at the base, surrounded by rings of oblong, keeled scales: throat expansible; a very slight fold before the shoulder. (Günth., Ind. Rept., p. 148, pl. 14, fig. F.)
4. Physignathus mentager.
Dorsal crest not interrupted above the shoulder; interrupted above the hip: caudal crest as high as that on the back: no large scales on the side of the neck: sides of the throat with large convex or tubercular scales.
A high crest, composed of sabre-shaped shields, extends from the nape of the neck to the second fifth of the length of the tail, being interrupted above the hip: scales on the back and the sides of equal size, very small, with an obscure keel obliquely directed upwards; those on the belly smooth, on the lower side of the tail rather elongate; strongly keeled: tympanum distinct: throat with a cross-fold: orbital edges and sides of the neck without spines: tail transversely banded with black.
One stuffed specimen is 30 inches long, the tail taking 21. (Günth., Proc. Zool. Soc., 1861, April 23, and Ind. Rept., p. 153, pl. 15.)
5. Tropidophorus microlepis.
Snout rather narrow and produced: scales on the back strongly keeled, the keels not terminating in elevated spines: back of the tail with two series of moderately elevated spines, the series not being continuous with those on the back of the trunk: scales of the throat smooth, or very indistinctly keeled: tail with a series of plates below, which are much larger and broader than the scales of the belly: three large præanal scales: a single anterior frontal shield (internasal). (Günth., Proc. Zool. Soc., 1861, April 23, and Ind. Rept., p. 76, pl. 10, fig. A.)
