Description——Body long and slender, with short, blunt 
tail bearing a small spine at its tip. Head small, continuous 
with neck, slightly depressed, with prominent rounded snout. 
Rostral plate strongly recurved on top of snout, and con- 
tinued back on lower surface of head to mouth. A large 
nasal plate extending to lip, divided behind, and sometimes 
in front of, nasal opening. Ocular plate reaching margin 
or lip between labial plates. Usually one labial behind 
ocular and one or two between it and nasal. Usually two 
large plates, parietal and occipital, behind ocular. Nasal, 
parietal, and occipital plates separated from corresponding 
plates on opposite side of head by a single series of small, 
rounded, imbricate scales on head behind rostral. Oculars 
separated from this central series by a pair of small supra- 
ocular plates. Infralabials four or five, similar to the small 
scales on the chin. Fourteen rows of strongly imbricate 
scales; ventral series often slightly enlarged. Preanal large, 
single. Caudal scales similar to those on body.
