Description of Type-specimen . — Adult male. Head and body 51 mm., 

 tail 84 mm. Body and head depressed. Upper head plates large and 

 smooth and somewhat convex; interparietal largest; four enlarged supra- 

 oculars, separated from frontal by one row of granules ; frontal divided 

 transversely; a pair of prefrontals preceded by three large hexagonal 

 plates and these in turn by six small plates in pairs. Four supralabials 

 and five infralabials to below the eye. Gular scales smooth, scales on 

 edge of fold enlarged. Lateral neck scales granular, grading into some- 

 what larger ones on the dorsal surface. Dorsals increasing in size from 

 the head posteriorly, but still small and not distinctly keeled above the 

 shoulders. Dorsal body scales small and feebly keeled, about 27 equaling 

 the distance from the end of the snout to posterior margin of the inter-
