 Snout low, rounded and rather short, with well-developed 

 canthus. Nostrils large, opening upward and outward, 

 nearer to end of snout than to orbit. Plates on head large, 

 smooth and usually more or less convex 5 interparietal larg- 

 est. Frontal plate usually divided transversely. Three to 

 five supraoculars, enlarged, and separated from frontals by 

 one ^ow of granules. Superciliaries long, somewhat project- 

 ing laterally, and strongly imbricate. Central subocular 

 very long, narrow, and strongly keeled. Rostral and supra- 

 labials very long and low. Other plates of upper surface 

 of head very irregular in size and position. Symphyseal 

 plate rather small, followed by three or four pairs of larger
