Description.—Head rather wide, little distinct from neck. 
Snout rather broad, rounded, greatly depressed, pointed in 
profile. Rostral plate very large, broad, prominent, exten- 
sively reverted on upper surface of snout, often reaching 
prefrontals, and otherwise bounded behind by two plates on 
each side of head, these being a large plate, corresponding 
to the internasal and nasals merged, and the first supralabial. 
Plates on top of head are the naso-internasals, a pair of pre- 
frontals, a frontal, supraocular of each side, and a pair of 
rather short parietals. Posterior nasal small, sometimes 
merged with anterior nasal and internasal, rarely distinct. 
A small loreal very rarely present, normally none. One 
preocular. Two postoculars. Temporals one followed by 
one. Supralabials seven, third and fourth reaching eye, 
second, third and fourth high. Inferior labials usually
