128 SAURIA. 



The trunk is compressed in the male and rounded in the female ; its back is covered with 

 small keeled scales, larger than those on the sides, which are directed obliquely downwards ; 

 a few large scales are intermixed between the small ones ; those on the belly rather larger 

 than the dorsal, strongly keeled ; praeanals small. A very low crest on the neck is peculiar 

 to the male. Tail long, scarcely compressed at the root ; all its scales are keeled, and 

 those on its lower side as broad as long, scarcely different from the others. 



The limbs are exceedmgly long, the hind limb extending far beyond the extremity of the 

 snout, if laid forwards ; the fourth hind toe is nearly twice as long as the third. 



Brownish olive ; male generally with a whitish band along each side of the back ; six or 

 seven brown cross bars on the middle of the back between the bands ; legs and tail witli 

 brownish transverse bands. A brown band broadly edged with whitish between the orbits ; 

 throat and an oblique streak from the eye to the angle of the mouth white; gular sac 

 immaculate ; throat of the female sometimes brownish. Sometimes nearly uniform brownish 

 olive. 



This species, though local, does not appear to be scarce in Ceylon ; Peters (Monatsber. 

 Berl. Acad. 1860, p. 184) mentions its occurrence at Trincomalee, Hinida, Ratnapura, and 

 on Adam's Peak. An adult male measures 10 inches, the tail measuring 7 ; the length of its 

 hind leg is 3^ inches. It is evidently a Tree Lizard.

 vertebral line ; superciliary margins ])ointed behind. Gular appendage 

 moderately developed. The adult with a globular hump on the nose. 



Only one species is known.

The hump on the nose is globular, covered with small shields ; it appears to be present 

 in both sexes, but in very young specimens it is entirely absent. Canthus rostralis sharp
