Description. — Head and body very large, much de- 

 pressed, the latter very broad. Head almost triangular, 

 with narrow rounded snout, and covered with small plates 

 largest on frontal and temporal regions. Nostrils opening 

 upward, outward, and slightly backward, in round plates a 

 little nearer to end of snout than orbits. Superciliaries like 

 supraoculars, small and juxtaposed. Suboculars all short, 

 but strongly keeled. Rostral plate very small. Labial 

 plates small and of about equal size. Symphyseal plate 

 long but very narrow. Several series of slightly enlarged 

 sublabials passing gradually into the finely granular gulars. 

 Gular fold covered with very small scales. Ear-opening
