Description. — Head short, rounded and rather high. 

 Nostril opening laterally in a single rounded plate which is 

 separated from the large rostral rarely by two rows (20%) 

 but usually by one row (80%) of granules. Supra- 

 ocular regions separated from each other by three series of 

 small convex plates 5 covered with very small plates and 

 granules. A large subocular, followed and preceded by 

 smaller ones. A series of long, strongly imbricate super- 

 ciliaries. Labials small, about equal in size, and from nine 

 to 13 in number in each series. Symphyseal plate nearly 

 triangular, and forming the apex of a V-shaped series of 

 slightly enlarged plates. Gulars small, either convex or 

 flattened. Eye -lids very slightly fringed. Ear-opening 

 very large, almost vertical, and with weak anterior denticu-

 keeled scales. Other dorsals small, keeled, juxtaposed, and 

 in series which converge toward the dorsal line posteriorly. 

 Ventrals larger than dorsals, smooth and imbricate. Sides 

 covered with small granular scales. Tail long, tapering, 

 slightly crested and with whorls of obliquely keeled scales.
