The Nilgiri keelback or Beddome's keelback (Amphiesma beddomei ) is a species of snake found in the Western Ghats in India.[1] The species is named after Richard Henry Beddome, 1830–1911, British army officer and botanist.[3] It was first discovered near the Nilgiris but is now known more widely from the Western Ghats. This snake is terrestrial and feeds on toads.

- See snake scales for the terminology used
Eye moderate, its diameter in the adult equalling its distance from the nostril; rostral just visible from above; suture between the internasals as long as that between the prefrontals; frontal larger than its distance from the end of the snout, a little shorter than the parietals; loreal as long as deep or deeper than long; one preocular; three (rarely two) postoculars; temporals 1+1 or 1+2; upper labials 8 or 9, third, fourth and fifth, or fourth, fifth, and sixth entering the eye; 5 lower labials in contact with the anterior chin shields, which are shorter than the posterior.
Scales in 19 rows, rather strongly keeled, the outer however, perfectly smooth. Ventrals 131-150; anal divided ; subcaudals 65-75.
Brown above; a series of yellow spots, each between two black spots or short transverse bands, along each side of the back; upper labials yellowish with black sutures; a yellow, black-edged, oblique streak from the eye to the gape; a yellow band across the nape, behind the parietals, becoming indistinct with age; belly white, closely dotted with brown on the sides.
