Etymology

edit

The specific name, layardi, is in honor of British naturalist Edgar Leopold Layard.[2]

Habitat & geographic range

edit

N. layardi is a poorly known skink from the hills of the Central Province and the wet zone coastal areas. Known localities include Millawa, Wellawatte, Lunava, and Polgahawela. It inhabits moist soil and decaying leaf litter, especially at the base of trees, at elevations up to 150 m (490 ft).

Description

edit

The snout of N. layardi is subconical. A single loreal is present. The limbs, an ear opening, and supranasals are absent. The dorsum is brown, each scale with a darker margin.

Reproduction

edit

The eggs of N. layardi are deposited in heaps of coconut leaves or in silt over stony substratum. The eggs are soft-shelled, measuring 6.4 mm × 15.9 mm (0.25 in × 0.63 in), and two eggs are produced at a time around March.
