Synopsis of the Species. 



I. The suture between the rostral and first upper labial falls below 

 the centre of the nostril. 



A. Ventral scales smooth. 

 Snout twice as long as the distance 



between the orbit and the ear-opening ; 



latter oval, its diameter half or three 



fifths that of the orbit ; femoro-prseanal 



pores 14 to 22 altogether 1. cepedianum, p. 211. 



Snout twice as long as the distance 



between the orbit and the ear-opening ; 



latter round, one fourth or one third 



the diameter of the orbit ; 24 to 30 



pores altogether 3. andamaneme, p. 212. 



Snout not twice as long as the distance 



between the orbit and the ear-opening ; 



latter oval, its diameter not half that 



of the orbit ; gular granides as large 



as the ventral scales; 10 to 12 pores 



altogether 4. newtonii, p. 212. 



Snout nearly twice as long as the distance 



between the orbit and the ear-opening ; 



latter oval, measuring one third the 



diameter of the orbit ; 45 or 46 pores 



altogether 5. guentheri, p. 213. 



B. Ventral scales keeled.

between the orbit and the ear-opening ; 



femoro-prseanal pores 33 to 50 alto- 

 gether 6. madagascariense.
