Head oviform, depressed ; snout longer than the distance between 

 the eye and the ear-opening, once and a half the diameter of the 

 orbit ; ear-opening round or suboval, two fifths the diameter of the 

 eye. Body and limbs moderate. Digits less dilated than in the 

 preceding species, the basal dilatation not being quite as wide as 

 the apical ; the lamellae also fewer, only the two or three distal 

 ones divided. Upper surfaces covered with minute granular scales, 

 larger on the snout. Hostral four-sided or subpentagonal, about 

 twice as broad as high, with median cleft above ; nostril pierced 

 between the rostral, the first labial, and four or five nasals ; ten or 

 eleven upper and as many lower labials ; mental small, triangular ; 

 no regular chin-shields, but small polygonal scales passing gradually 

 into the minute granules of the gular region. Abdominal scales 

 hexagonal, smooth, subirabricate. No praeanal pores. Tail de- 

 pressed, oval in section, tapering ; when intact its width is con- 

 tained at least six times in its length ; it is covered with uniform, 

 small, flat hexagonal scales ; four or five largo tubercles on each side 

 the base of the tail in the males. Light brown above, variegated 

 with darker ; two zigzag dark-brown lines on the back, enclosing 

 rhomboidal spots of the lighter ground-colour ; sides and limbs with 

 small light spots ; lower surfaces whitish.

Very closely allied to the preceding. Distinguished by the smaller 

 head, the rather shorter snout, the more elongate body, the perfectly 

 cylindrical tail, and the presence of praeanal pores in the male ; latter 

 ten to twenty. Pale brown, middle of back and tail paler, with a 

 zigzag brown line on each side.
