The head is broad and low. The snout is rounded 

 when viewed from above, but sharply pointed when seen 

 in profile. The nostrils are large and superior. There 

 is a strongly marked canthus rostralis. The very large 

 interparietal plate is broader than long. There are two 

 or three series of enlarged supraoculars. The other head 

 plates are small and irregular, largest on the frontal and

 is a very long suborbital. The eyelids are heavily fringed. 

 The labials are low, but long, imbricate, and projecting

 region, longer than wide. The gular fold is covered
