The body is rather slender, with short, tapering tail. 

 The head is slightly distinct from the neck, and ends 

 in a narrow snout which projects far beyond the lower 

 jaw. The head-plates are normal. The nasal plates 

 rarely unite above the nostril. One (or two) preoculars 

 and two (or three) postoculars are present, as is also a 

 small loreal. Temporals are normally two followed by 

 three. The scales are smooth, in seventeen to twenty- 

 five rows, with apical pits. The anal plate is divided. 

 Urosteges are in one series, except usually toward the 

 end of the tail. The eve is of moderate size, with 

 round pupil.
