The body is long but rather stout, with tail of mod- 

 erate length. The neck usually is slightly constricted, 

 so that the head appears little distinct from it. The 

 snout is long, narrowly rounded, and projecting beyond 

 the lower jaw. The head-plates show many variations, 

 but when typical are normal except that there are four 

 prefrontals. The nasals are usually distinct. One or 

 two preoculars, two to four postoculars, and a loreal are 

 present. Temporals are many and very variable. The 

 scales are in twenty-seven to thirty-five rows, the dor- 

 sals keeled, some of the lateral rows smooth. The anal 

 plate is single. Urosteges are in two series. The eye 

 is large, with round pupil.
