[1] The species is named after Richard Henry Beddome, 1830–1911, British army officer and naturalist.

The eye of S. beddomei is moderate in size, its diameter in the adult equaling its distance from the nostril.

The frontal is larger than its distance from the end of the snout, a little shorter than the parietals.

There is a yellow, black-edged, oblique streak from the eye to the corner of the mouth.

[1] Although not aquatic, S. beddomei can be found actively hunting from dawn to dusk on stream banks or close to other bodies of water.
