Description
In the genus Atractus the maxilla is short, with 8–12 teeth; the maxillary and mandibular teeth decrease in size posteriorly. The head is not distinct from the neck. The eye is small, with a round or subelliptic pupil. The nostril is between two nasal scales. The preocular is usually absent, and the loreal and prefrontal scales enter the orbit. The body is cylindrical. The dorsal scales are smooth, without apical pits, in 15 or 17 rows. The ventral scales are rounded. The tail can be either short or rather long. The subcaudals are paired.[1]
