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, convex or almost flat 5 interparietal largest. Fron- 

 tal plate usually divided transversely. Inner series of en- 

 larged supraoculars separated from frontal, frontoparietal 

 and parietal plates by one or two rows of granules. Super- 

 ciliaries long, very slightly projecting laterally, and strongly 

 imbricate. Middle subocular very long, narrow, and 

 strongly keeled. Rostral very wide and rather low. Four 

 to seven long low supralabials. Symphyseal plate moder- 

 ately 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 subhexagonal granules, largest cen- 

 trally and becoming imbricate on the strong transverse fold. 

 Edge of fold with a series of projecting scales. Ear-open- 

 ing large, with an anterior denticulation of from two to five 

 pointed scales of much variation in size and shape. About 

 two rows of medium-sized or small scales along middle 

 of back, bordered on each side by about two rows of much 

 larger more or less strongly keeled scales normally of more 

 or less equal size in the two rows both of which usually 

 extend forward to or onto the neck. Other dorsal scales very
