The Round Island burrowing boa (Bolyeria multocarinata)

Round Island in 1975. There are no recognized subspecies.[5]

Description

B. multocarinata reached about 1 m (3 ft 3 in) in total length (including tail). Preserved specimens have been reported as having total lengths of 54–140 cm (1.77–4.59 ft). Its colour was described as light brown with blackish spots

dorsally, and pink marbled with blackish ventrally. It had a pointed snout with a cylindrical body and head. Its general body form suggests that the Round Island burrowing boa had fossorial tendencies. This species' closest living relative is the Round Island boa (Casarea dussumieri).[citation needed
]

Geographic range

The Round Island burrowing boa had an extremely small range of only 1.5 square kilometres (0.58 sq mi). Its habitats were hardwood forests and palm savanna. In the past it was found in

type locality given is "Port Jackson" (in error).[3]

Habitat

The preferred natural habitat of B. multocarinata was forest.[1]

Diet

The diet of B. multocarinata is unknown, but it is thought to have eaten lizards and their eggs, as well as the chicks and eggs of ground-nesting and burrowing seabirds.[1]

Reproduction

B. multocarinata was oviparous.[7] Clutch size was about five eggs.[1]

Conservation status

The species Bolyeria multocarinata is classified as Extinct (EX) on the

IUCN Red List of threatened species (v2.3, 1994).[1] It was already rare by 1949 and was last seen by conservationists in 1974. Reasons for its extinction are habitat loss caused by soil erosion due to overgrazing by goats and rabbits and heavily persecuted by early settlers.[6]
