Distribution
Widely distributed along the continental margin of the western Indian Ocean, from the Gulf of Oman southwards to eastern South Africa, at depths of 50–400 m (living 75–120 m) (Herbert 2015) and recently recorded from the Philippines (Poppe & Tagaro 2020). Found on the slopes of Walters Shoal, at depths of 256–490 m (none collected alive).
Remarks
Emarginula undulata is a distinctive species on account of its thin shell with numerous fine, concentrically elongate intritacalx pits, raised selenizone and relatively few, broad, radial ridges with widely-spaced, conical bumps.
