Head twice as long as broad, much longer than the tibia ; fore- 

 head slightly concave, no frontal ridges ; upper head-scales rather 

 large, smooth, only five longitudinal series between the canthals ; 

 scales of the supraorbital semicircles large, in contact medially ; 

 five to ten enlarged, smooth supraocular scales, in contact with the 

 supraorbitals ; occipital much larger than the ear-opening, in con- 

 tact with the supraorbitals ; canthus rostralis short ; loreal rows 

 two ; eight or nine upper labials ; ear-opening very small, sub- 

 triangular. Scales small and smooth, the ventrals largest, rounded, 

 the dorsals a little larger than the laterals, with two median rows 

 slightly prominent. The adpressed hind limb reaches the axilla ; 

 digital expansions well developed. Tail round, with equal smooth 

 or feebly keeled scales. Brownish above, the body with indistinct

Rostral plate produced into a flexible appendage ; a shallow 

 frontal concavity ; lateral occipital crests prominent ; upper head- 

 scales large and smooth, only three rows between those of the 

 canthus rostralis at the middle ; supraorbital semicircles in contact 

 along the entire median line and with the occipital, which is large ; 

 loreal rows two ; ear-opening small ; a series of large chin-shields 

 in contact with the lower labials throughout. Scales of the body 

 smooth, of nearly equal size ; those of the tail larger, the median 

 superior series not diiferent from the others. Limbs short, the ad- 

 pressed hind limb falling considerably short of the axilla ; digital 

 expansions rather narrow. Colour above dark grey, below pig- 

 mented white ; the two colours are abruptly defined below the 

 orbit and the scapula, and there are brown spots behind the axilla ; 

 tail distantly annulate. 



Total length 139 millim.
