 as supraocular region, longer than its distance from snout and 

 longer than the combined parietal length, touching four supra- 

 oculars; seven or eight supraoculars, the last two small, first 

 narrowly in contact with prefrontal; frontoparietals separate, 

 longer than wide; interparietal small, longer than wide, the
