of the mouth; male with two large, compressed, tubercular, bony 
processes, directed upwards and outwards ; head-scales very unequal 
in size; a dermal lobe on each side, behind the temple. Body and 
limbs finely granular, with scattered flat round tubercles ; the scales 
larger on each side of the vertebral line, which is devoid of a regular

Casque feebly elevated, posterior border angular; a more or less

commissure of the mouth and the extremity of the casque equals the 
length of the mouth ; lateral crest tubercular, entirely surrounding 
the casque; snout of male produced in a more or less elongate tu- 
bereular bony process, concave above and directed slightly upwards ; 
upper head-scales very unequal in size; two very large occipital 
dermal flaps, in contact behind the extremity of the casque, covered 
with unequal-sized round flat tubercles, the largest of which con- 
siderably exceed in size those on any other part of the a and body.
