Body nearly tubular and somewhat compressed posteriorly; dorsal and anal fins not externally evident except near tip of tail, where they are confluent with short caudal fin; center of eye a third closer to tip of snout than to rictus; anterior nostrils very short, tubular, on each side of tip of snout, scarcely longer than posterior nostrils, these latter tubular, single, on each side; a vertical line through center of base of rear nostril passes through rear of pupil; anus a little in.

Schultz.) front of middle of total length; distance between pore above base of anterior nostril and pore on dorsal surface of snout contained about times in distance between latter and rear nostril, all three not quite in line; distance between rear nostrils about equal to eye; jaws equal; teeth very numerous, long, pointed, those on maxillary in several slightly oblique rows, teeth in outer rows small, in inner rows canine- like; dentary with similar dentition; vomerine teeth uniserial, sepa- rated from the premaxillary teeth by a short edentulous area; gill openings notably nearer middorsal line than middle of sides.
