Orobophana juddii (Pilsbry & Cooke)

Judd’s Orobophana Snail (Orobophana juddii)

Judd’s Orobophana Snail was described in 1908, it is known only from subfossil remains that had been found in sand dunes on the beaches in the Koloa District in southern Kaua’i, Hawaiian Islands.

The shells were semiglobose with a flattened base and a rounded periphery, they reached sizes of about 0,42 cm in height and 0,46 cm in diameter, the original colors are not preserved. [1]

Judd’s Orobophana Snail was amongst the first snail species that disappeared following the arrival of the first Polynesian settlers and especially the Polynesian Rats (Rattus exulans (Peale)) they brought with them.
