Drysdalia is a genus of snakes, commonly known as crowned snakes, belonging to the family Elapidae. The three species in this genus are venomous snakes, but not considered deadly.
The species formerly known as Drysdalia coronata (Schlegel, 1837), commonly known as the crowned snake, was assigned to the genus Elapognathus Boulenger, 1896, by Keogh et al. in 2000. Its current correct scientific name is Elapognathus coronatus (Schlegel, 1837).
Crowned snakes are small snakes, averaging about 50 cm (20 inches) in total length (including tail) but can be as small as 18 cm (7 inches). They are normally brown in colour.
