The body is cylindrical, covered with smooth, cycloid 

 scales. The rostral plate is very large, and is recurved on 

 both the upper and lower surfaces of the protruding snout. 

 The nasal plate is very large; behind it is the large ocular, 

 followed in turn by wide parietal and occipital plates. A 

 row of small scales runs along the top of the head behind 

 the rostral plate. This central row of scales is separated 

 from the ocular plate of each side by a small supraocular 

 plate. 



One species of this genus has been found in Arizona.
