moderate, smaller than the eye-opening; three prefrontals, azygos 
slightly larger, nearly as broad as long, in contact with the frontal on 
a very small point, separated from the loreal by one shield and from 
the rostral by two pairs of shields; frontal not twice as long as broad ; 
parietal on each side separated from the frontal and supraoculars by 
two shields ; nasal in contact with the rostral; a small supranasal, 
a postnasal; second loreal higher than long; rostral much broader 
than mental ; ten or eleven upper labials, suture between sixth and 
seventh, or seventh and eighth, below the centre of the eye; four or 
five chin-shields on each side, first or first two in contact with the 
lower labials. Body subtetragonal. Thirty-seven or thirty-nine 
scales round the middle of the body; dorsals somewhat pointed pos- 
teriorly, obtusely keeled and, as well as the laterals, finely striated. 
Limbs rather short, failing to meet when adpressed ; digits short ; 
claws nearly entirely concealed in a large compressed sheath formed 
of a larger supero-lateral and a smaller inferior scale*. Tail 
slightly compressed posteriorly, scaled like the body. Brown above, 
with transverse whitish dark-edged narrow bands, which may be

by asmall shield, and from the rostral by two pairs of shields;
