Head pyramidal ; snout pointed, about twice as long as the dia- 
meter of the orbit, which nearly equals the vertical diameter of the 
tympanum. Rostral pentagonal, scarcely visible from above, sepa- 
rated from the large hexagonal or octagonal frontonasal by the pair 
of anterior nasals which form a short suture; the frontonasal is in 
contact on each side with the posterior nasal and the first loreal, 
posteriorly with the preefrontals; latter three, median abnormally 
missing, sometimes very small and enclosed between the laterals and 
the frontals, sometimes larger than the laterals and in contact with 
the frontonasal, laterals extending over the canthus rostralis to the 
second loreal; frontals large, extending to the supraciliary edge, 
forming a longitudinal suture between the azygos prefrontal and 
the interparietal; latter hexagonal, elongate, separating the pair of 
frontoparietals, which are much broader and a little shorter; a pair 
of parietals, the largest head-shields; two large temporals on each 
side, anterior largest and in contact with the frontoparietal and the 
parietal ; nostril pierced between two nasals and the first labial; 
two loreals, second largest ; two postoculars ; seven or eight upper
