Snake psammophis phillipsii du gabon
Etymology
The generic name Psammophis was coined by the German herpetologist Heinrich Boie in 1826, a compound of the Hellenistic Greek ψαμμο, "sand" + Classical Greek ὄϕις, "snake", thus sand-snake.
Description
The maxillary teeth are 10 to 13 in number, with one or two in the middle much enlarged and fang-like, preceded and followed by an interspace; the two posterior teeth are grooved. The anterior mandibular teeth are long, and the posteriorteeth are small. The head is elongated and distinct from the neck, with an angular canthus rostralis. The eyes are rather large, with round pupils. Its body is elongated and cylindrical with smooth scales in 15 or 17 rows, with apical pits. Ventral scales are rounded or obtusely angulated laterally, and the tail is long with the subcaudals in two rows.
Geographic range
Thirty-four species of Psammophis are known, from Africa and southern Asia.
Behavior
Psammophis species are chiefly sand-snakes, but they are also found on low bushes.
Diet

The following 34 species are recognized as being valid.
Nota bene: A binomial authority in parentheses indicates that the species was originally described in a genus other than Psammophis.
