 single nasal, no supranasal : frontonasal broader than long, forming 

 a suture with the rostral and with the frontal; latter as long as or 

 a little longer than frontoparietals and interparietal together, in 

 contact with the two anterior supraoculars ; four supraoculars ; 

 eight or nine supraciliaries ; frontoparietals and interparietal dis- 

 tinct, of equal length ; parietals forming a suture behind the inter- 

 parietal ; one or two pairs of nuchals ; usually the fourth, sometimes
