PLATE XIII.—FIG. 2.

DESCRIPTION.—Head almost equilaterally triangular, the muzzle rounded;

scales of the head small, nearly equal, rounded, not imbricated,

those of the temples subconical; nostrils round, large, confined

to the nasal scales. Ears rather large, the tympanum lying beneath

the surface, and partly concealed by an anterior fold of skin,

which is not denticulated, as in _Oplura_. Skin of the neck folded

at the sides, that of the body flaccid, and with strongly marked

lateral folds, extending from the shoulder to the thigh. Scales of

the neck and back very small, round, slightly convex, very smooth.

Skin of the throat rugose, with a transverse pectoral fold not

very strongly marked. Scales of the throat similar to those of the

back; those of the belly broader and less convex; all perfectly

smooth. Tail about the length of the head and body, flattened at

the base, then round, surrounded with strong spinous verticillated

scales, of which there are about fifty circles; beneath smooth.

Legs of moderate length, strong, covered with small conical,

imbricated scales. The toes compressed towards the extremity, and

terminated with a strong, short, compressed nail.

COLOUR.—The colour can only be partially described, as the specimen

has been long in spirits. It is of a dark brown colour above, with

darker, obscure markings on the body. About the head are traces of

green. The tail and limbs are rich brown, and the under parts

dull, pale fuscous.
