Colour. — Top of the head umber-brown, variegated with three deep 

 orange coloured brown spots, one between the eyes, and the other two on the 

 hind head. Eyebrows and lips greenish white, the former connected by a 

 narrow white line which edges the anterior part of the head. The middle of 

 the back dull yellowish brown, variegated towards the head with two and 

 towards the tail with three rows of small, somewhat square, brownish red 

 spots, very little darker than the ground colour, and only distinct in fresh 

 specimens or in those observed in spirits. The sides of the back chequered 

 white and liver-brown, the latter rather the predominant colour, and disposed 

 in the form of small irregular quadrangular spots, arranged in two rows, 

 each of which, as well as each individual spot, being parted by the interven- 

 tion of a narrow streak of white. Sides of body similarly coloured as the 

 back, only the different tints are darker. Tail above coloured like the back, 

 but the chequered lines diminish in width and regularity as they distance its 

 base, and almost disappear towards the tip. Throat and belly pale aurora- 

 red tinged with coppery green, the plates towards the sides of the belly 

 strongly clouded with brownish red, and the central portion of each of the 

 scales of the throat also of that colour ; under surface of tail greenish white 

 or pale broccoli-brown, and variegated with small irregular spots of light 

 brownish red, the centre of each scale being of the latter colour. Legs and 

 toes aurora-red, freckled towards body with irregular spots of umber-brown. 



Form, &c— Figure fusiform, the tail tapered to a point. Head, body, and 

 base of tail depressed, and the upper aspect of the two latter slightly arched. 

 Head small, muzzle rather lengthened, and its point obtuse and rounded. 

 Frontal plate oblong, five-sided, the anterior side arched. Fronto-nasal 

 plate large, and its hinder edge slightly concave ; no distinct inter-fronto-
