passing gradually into the minute granules of the throat. Temples 

 and upper surface of body, limbs, and tail covered with small 

 granular scales intermixed with scattered, roundish, triangular, 

 keeled tubercles, which form eighteen to twenty-two longitudinal 

 series on the middle of the body. Lower surfaces covered with 

 smaU. imbricated smooth scales. TaU cylindrical, tapering, tipper 

 surfaces with alternate yeUowish-green and brown cross bands ; 

 lower surfaces dirty white.

Head oviform, longer than broad, very convex ; snout rounded, a 

 little shorter than the distance between the eye and the ear-opening, 

 slightly longer than the diameter of the orbit; forehead not concave; 

 ear-opening small, roundish. Body short. Limbs moderate. Digits 

 depressed in their basal part, with three series of scales inferiorly, the 

 central series of which is slightly enlarged transversely ; digital ex- 

 pansion rounded, scarcely wider than the basal part, measuring about 

 half the diameter of the eye. Upper surface of head covered with 

 small convex granules, largest on the snout ; rostral subpentagonal, 

 nearly twice as broad as high, with median cleft above ; nostril 

 pierced between the rostral, the first labial, and three small nasals, 

 which are generally not distinguishable from the surrounding gra- 

 nules ; six or seven upper and as many lower labials ; mental pen- 

 tagonal ; a row of small chin-shields, the two median largest, and 

 in contact with the mental ; behind these, convex granules becoming 

 gradually smaller. Upper surface of body and limbs covered with 

 flat, smooth, subimbricate roundish scales, as large as the granules 

 on the snout ; abdominal scales larger, hexagonal, imbricate, smooth. 

 Tan cylindrical, tapering, covered with imiform, strongly imbricate 

 smooth scales. Upper surfaces greyish brown, generally with four 

 or six dark-brown longitudinal lines on the back and tail, sometimes 

 replaced by transverse undulated brown lines ; head generally varie- 

 gated with dark brown ; a dark line passing through the eye ; 

 lower surfaces brownish white.
