Description. — Body and head considerably depressed; 

 snout low, rounded and rather long; nostrils large, opening 

 upward and outward nearer to end of snout than to orbits. 

 Head plates large, smooth, nearly flat, interparietal lar- 

 gest; frontal divided transversely; four to five enlarged 

 supraoculars, separated from the frontals and frontoparie- 

 tals by one or two series of granules. Superciliaries long, 

 narrow and projecting. Central subocular very long, nar- 

 row and strongly keeled. Rostral and supralabials long 

 and low; usually six or seven supralabials. Symphyseal 

 moderately small, followed by two or three pairs of larger 

 plates separated (except first) from the infralabials by one 

 or two series of moderately enlarged sublabials. Gular re- 

 gion covered with small, smooth, hexagonal or rounded 

 scales which change gradually to granules on sides of neck 

 and to larger imbricate scales on strong gular fold, largest 

 on denticulate edge of gular fold where somewhat larger 

 than ventrals. Several enlarged plates in front of ear-open- 

 ing. Ear denticulation moderately long, of two to four 

 scales, the largest exceeding in length diameter of largest 

 plate in front of ear. Back covered with scales of nearly uni- 

 form size changing rather abruptly to granules near the 

 dorsolateral line, scales of central region strongly keeled,
