Description. — Head and body considerably depressed. 

 Snout rounded but rather narrow, with well-developed 

 canthi, above which the nostrils open much nearer to end of 

 snout than to orbits. Plates on head moderately large, 

 smooth and almost flat; interparietal largest. Frontal plate 

 usually divided transversely. Inner series of enlarged supra- 

 oculars separated from frontal, frontoparietal, and parietal 

 plates by one or two rows of granules. Superciliaries long, 

 very slightly projecting laterally, and strongly imbricate. 

 Middle subocular very long, narrow, and strongly keeled. 

 Rostral very wide and low. Four to six long low supra- 

 labials, to below middle of eye. Symphyseal plate mod- 

 erately large, followed by series of large plates in contact 

 with first pair of lower labials but separated from the others 

 by one or two rows of sublabials. Chin and gular region 

 covered with smooth round or subhexagonal granules largest 

 centrally and becoming imbricate on the strong transverse 

 fold. Edge of the fold with a series of projecting scales. 

 Ear-opening large, with a rather short anterior denticula- 

 tion of from two to four pointed scales of much variation 

 in size and shape. One or two rows of medium-sized scales 

 along middle of back, bordered on each side by one to three
