Dorsal scales rhomboidal, keeled, juxtaposed or subimbricate; laterals a little smaller ; 40 scales across the middle of the body ; 2 or 3 lateral scales correspond to the length of a ventral plate. Ventrals tetragonal, broader than long, in 8 longitudinal and 24 transverse series; the plates of the series next to the median nearly twice as broad as the one on the inner side and once and a half the one on the outer side; the outermost plates very small. Preanal with a large plate in front of it. The hind limb reaches the collar-fold. Scales on upper surface of tibia smaller than dorsals. Femoral pores 16-17. Upper caudal scales strongly keeled, with truncate or obtusely pointed posterior border. Brown above, darker on the sides, which are stellate with small white, black-edged ocelli; upper surface of head and back with small black spots: a large black spot on each upper labial; uniform whitish beneath.” (Boulenger 1899)|
