Description. — " )Snout scarcely pi'ominent, rounded, as long as 

 the distance between the orbit and the ear-opening ; canthus 

 rostralis obtuse ; eye small, with rudimentary circular scaly lid ; 

 ear-opening oval, oblique. Tail, when intact, at least twice as 

 long as the body. Rudimentary hind-limbs measuring about the 

 distance between the eye and the end of the snout in females, 

 more than the distance between the posterior border of the eye 

 and 'the end of the snout in males. Ten to fourteen prajanal 

 pores. Rostral low, from twice and a half to thrice and a half as 

 broad as high ; nostril between the first labial and three nasals, 

 the two anterior of which are band-like and extend across the 

 upper surface of the snout, where they form a suture with their 

 fellows, or are separated by one or two small azygos plates ; a 

 large polygonal prtefrontal, separated from the nasals by two (or 

 one) pairs of small transverse plates, its transversely truncate 

 posterior border forming a suture with the frontal, which is 

 pentagonal and about once and two-thirds as long as broad ; the 

 posterior angle of the latter plate wedged in between the pair of 

 parietals, which are nearly as large as the frontal, and sub- 

 hexagonal ; sometimes a narrow band-like plate on the outer side 

 of the parietals ; two large supraorbitals ; loreal region with 

 numerous small polygonal plates, from four to seven in a row, 

 between the orbit and nasal ; five to seven upper labials, separated 

 from the orbit by a row of scales ; mental large, broadly trapezoid ; 

 four to six lower labials, the first or the first two much dilated 

 vertically. Keels of the dorsal scales forming regular lines on 

 the body, alternate on the tail. Twenty-two or twenty-three (in 

 one specimen twenty-one) longitudinal series of scales round the 

 middle of the body, ten smooth and twelve or thirteen (or eleven) 

 keeled. The enlarged ventral scales twice as broad as long, in 

 seventy to eighty-five longitudinal series. Two enlarged anal 

 scales separated from the perforated pravinal scales by one or two
