 rostral; supranasals separated by a single median scale; snout 

 with a distinct longitudinal depression in front and between eyes, 

 terminating posterior to nostrils ; eleven upper labials, the last 

 not posterior to posterior vertical of eye; scales on snout large, 

 those above labials largest ; nine lower labials ; mental very large, 

 followed by two pairs of enlarged chin shields, first pair touching 

 only first labial and forming a long suture behind mental ; second 

 pair smaller, touching first and second labials, separated by three 

 small scales ; several somewhat enlarged scales posterior to these 

 shields and bordering lower labials ; granules on chin and throat
