Etymology

R. beddomii is named after Richard Henry Beddome (1830–1911), who was a British army officer and botanist. [3]

Description

R. beddomii is a small species of skink, with a maximum snout-to-vent length (SVL) of 4 cm (1.6 in). [2]

The ear-opening is larger than the nostril. There is a single azygos prefrontal, nearly as large as the frontonasal. The fourth to sixth upper labials are located below the eye. The body is much shorter than in the other species of the genus, and the adpressed limbs meet or slightly overlap. The dorsal scales are sharply bicarinate. There are 26 scales round the middle of the body. R. beddomii is reddish brown above, with or without 2 or 3 lighter dorsal streaks. The sides have scattered minute whitish dots. There is usually a black blotch with a few white dots above the axilla. The lower surfaces are uniform whitish. [4]

All claws are completely retractile, each into a scale sheath. [2]

Geographic range

R. beddomii is found in India (Tenmalai, Travancore, Sharavati River, N Kanara district, Parambikulam). [5]

Habitat

The preferred habitat of R. beddomii is forest, at altitudes of 400–1,300 m (1,300–4,300 ft). [1]

Reproduction

R. beddomei is an oviparous species. Egg laying coincides with the southwestern monsoons. An adult female may lay a clutch of up to 3 eggs. Each egg measures about 9 mm (0.35 in) x 6 mm (0.24 in). [2]

<i>Ristella</i> Genus of lizards

Ristella is a genus of skinks, lizards in the family Scincidae. The genus is endemic to the Western Ghats of southwestern India. Member species are commonly known as cat skinks because of their retractile claws. This genus can be instantly identified by the presence of only four fingers in forelimbs in all the species. All the members look more or less similar, and are drab dark brown to blackish in colouration, with paler undersides. This poorly known group of lizards is diurnal, insectivorous, terrestrial to semi-fossorial in habits. They inhabit deep leaf-litter and grasslands in montane forests and rainforests.

Colonel Richard Henry Beddome was a British military officer and naturalist in India, who became chief conservator of the Madras Forest Department. In the mid-19th century, he extensively surveyed several remote and then-unexplored hill ranges in Sri Lanka and south India, including those in the Eastern Ghats such as Yelandur, Kollegal, Shevaroy Hills, Yelagiri, Nallamala Hills, Visakhapatnam hills, and the Western Ghats such as Nilgiri hills, Anaimalai hills, Agasthyamalai Hills and Kudremukh. He described many species of plants, amphibians, and reptiles from southern India and Sri Lanka, and several species from this region described by others bear his name.
