Body deep, compressed, head heavy, anterior profile concave, but 

 convex from front of dorsal to occiput. Mouth small, maxillary

 jaws each with a baud of villiform teeth, in front of which is a row 

 of larger conical teeth ; no other teeth in the mouth. Eye nearly 

 two in interorbital space in a specimen 8 in. long, 1J in smaller 

 specimens ; interorbital space nearly flat, slightly raised in the middle 

 and at the edges ; scales on top of head extending forward past middle
