 distinct indication of a parietal crest ; the distance between the 

 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- 

 bercular bony process, concave above and directed slightly upwards ; 

 upper head-scales very unequal in size ; two very large occipital
