 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
