Geographic range

Species of the genus Drysdalia are endemic to parts of southern and eastern Australia.

Species

Three species are recognized as being valid.[1]

  • Drysdalia coronoides (Günther, 1858) – white-lipped snake
  • Drysdalia mastersii (Krefft, 1866) – Masters' snake
  • Drysdalia rhodogaster (Jan & Sordelli, 1873) – mustard-bellied snake

Etymology

The generic name, Drysdalia, is in honour of Australian artist George Russell Drysdale.[2]

The specific name, mastersii, is in honour English-born Australian zoologist George Masters.[3]

Taxonomy

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).

Description

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.

Habitat

Crowned snakes inhabit woodlands, swamps, and heathland.

Diet

Drysdalia feed on frogs and lizards.

gollark: Perhaps, but the issue is that for some unfathomable reason you use a slice and such instead of `.startswith`, and as it turns out you forgot to update `message.content[:6]` to be the right length.
gollark: Did you know you can do that? Because really, `await` syntax is bad.
gollark: `version = (await (await db.execute("PRAGMA user_version")).fetchone())[0]`
gollark: Mine is slightly awful and ignores all discord.py idioms ever, but you know.
