Eudolium bairdii (Verrill & E.A.Smith, 1881) Description: Shell light in weight, ornamented with about 18 spiral ribs with a smaller rib between each. Major ribs on the posterior part of the body whorl with or without weak to strong beads. Varix on outer lip; lip finely toothed within. Columella callus thin, with underlying ribbing showing through; umbilicus closed. Colour white with major spiral ribs yellowish to reddish brown. Size: Up to 76 mm in length. Distribution: Atlantic, Mediterranean and Indo-West Pacific Oceans; in Australia, known only from Port Stephens to Ulladulla, NSW, at depths of 412–1829 metres. Rare. Synonym: Shells from the Indo-West Pacific have been called Eudolium lineata (Schepman, 1909). Figs. 1,2: Off Wollongong, NSW, in 500 m (C.301349)

gollark: Oh, I removed that.

gollark: ++potaTOS

gollark: I should add that to potatOS! It could be really neat.

gollark: It might be neat to just stick a slightly tagged copy up somewhere, and see how quickly it spreads around.

gollark: But secretly embed malware to include potato OS on it?
