Head more long than broad; snout longer than the distance 

 between the eye and the ear-opening, about one and one third 

 time the diameter of the orbit; forehead concave; ear-opening 

 moderately large, suboval. Rostral quadrangular, more broad 

 than high, with a median cleft above; nostril bordered by the 

 rostral, the first labial and three nasals, the top one the largest 

 and generally in contact with its fellow. Eight to eleven upper 

 and six to nine lower labials ; mental large, pentagonal. Three 

 pair of chin-shields, inner very large, elongate, forming a long 

 suture, outer small, often broken up into small scales (fig. 28); the 

 distance from the border of the lip to the extremity of the 

 median chin-shields equals the diameter of the orbit. Upper 

 surfaces and throat covered with small granular scales, largest 

 and flat on the back. Ventral scales large, imbricate. Male 

 with 14 to 22 oval femoral pores on each side in a double 

 curved line, angular in the middle. Tail depressed, with a
