rostral twice as broad as deep, with median cleft above ; nostril 

 between the rostral and five small scales; 8 upper and 7 lower 

 labials ; symphysial triangular, in contact with two chin-shields ; 

 a smaller chin-shield on each side of the median pair. Back covered 

 with small granules and trihedral strongly keeled tubercles forming 

 8 or 10 very regular longitudinal series ; on the sides, the enlarged 

 tubercles become juxtaposed, lose their keels, and pass gradually 

 into the rather large, imbricate ventral scales ; these form about 

 20 longitudinal series. Tail covered with imbricate scales, the 

 dorsals keeled ; a ventral series of transversely enlarged, lamellar 

 scales. Greyish brown above, with blackish spots or a \^'ide-meshed 

 network ; an irregular dark streak on each side of the head, passing 

 through the eye; each labial with a blackish spot; lower parts white; 

 upper surface of tail with whitish, black-edged transverse spots.
