Snout wedge-shaped, with angularly projecting labial edge; 
mouth inferior. Nostril close to the rostral, which is large and 
nearly reaches the posterior border of the supranasals; a small 
anterior and a larger second loreal, latter usually coalesced with the 
prefrontal on each side; frontonasal rather large, one half or two 
thirds the length of the frontal ; latter as broad as or slightly broader 
than long ; three or four very small supraoculars ; no supraciliaries ; 
a preocular; interparietal as long as broad, as long as or slightly 
shorter than the frontal; frontoparietals small; parietals band-like, 
narrow; a pair of nuchals, in contact with the interparietal; first 
and second upper labials smallest, in contact with the nasal, fifth 
much larger than the four anterior together. Ear hidden. Two 
azygos postmentals. Body much elongate, with angular latero- 
ventral edge, with two pairs of short tridactyle limbs ; the posterior 
limbs proportionately much more developed than the anterior, and a 
little longer than the distance between the fore limb and the anterior 
corner of the eye. 22 scales round the body, those of the back and 
of the two median ventral series narrower than the others. Two 
slightly enlarged preanals. Tail shorter than head and body, 
cyclotetragonal at the base, compressed and pointed at the end.
