 surface of the head ; eye very small, with distinct circular lid ; ear- 

 opening very small, oval, horizontal. Body and limbs moderate, 

 slightly depressed. Head covered with granular scales posteriorly, 

 with polygonal, flat, or more or less convex, considerably larger 

 scales on. the snout ; rostral about twice as broad as high, with 

 distinct median cleft superiorly ; nostril pierced between the first 

 upper labial and three or four small nasals ; eleven or twelve upper 

 and ten or eleven lower labials ; mental twice as broad as high 

 anteriorly, narrowed posteriorly ; the mental and labials followed 

 by very small chin-shields gradually passing into the minute granules 

 of the throat. Upper siirfaces covered with small granules; lower 

 surfaces with very small, slightly imbricated scales. Male with a 

 large median patch of praeanal pores and two series of femoral 

 pores. Tail long, cylindrical, covered with very small subequal 

 juxtaposed scales. The coloration varies considerably : the speci-
