edge of the nasal. Nasal, frontonasal and eye-shield distinct, the 

 three forming helow the edge of the upper lip, the frontonasal oh- 

 long, erect, short, only reaching to the level of the eye, the eye- 

 shield large. Crown with 3 series of shields, the central series 

 small, 6-sided, the lateral ones ohlong, transverse. Eyes distinct. 

 Preanal shields subtriangular, produced behind. Tail rather 

 elongate, slightly tapering, with a conical tip, and 3 series of broad 

 6-sided scales beneath. 



From the structure of the nasal shield of this genus, it appears 

 that in this family the nostril is normally placed between two 

 shields (the nasal and supranasal), and that these two shields are 

 more or less perfectly united in front of the nostrils in the differ- 

 ent species.
