Type material. Holotype, USNM 860145.

Type locality. Off South Shetland Is., 67º27’S, 57º58’W, 809–1,116 m collected by R/V “ELTANIN”, St. 426.

Material examined. CNP-Inv.1876, St. 8, CAV2014, 6258.36’S, 6051.47’W in 219–232 m depth, 1 specimen; MACN-In 35050, 2 specimens, 25 de Mayo Is., South Shetland Is.

Distribution. South Orkney Islands, South Shetland Islands, West Antarctic Peninsula and Amery Ice Shelf ( Aldea and Troncoso, 2010).

Remarks. The description of this species was based on the presence of two sharp keels along the whole shell instead of only one and two in the last whorl from congeneric and sympatric A. magnifica . The shell of both Antarctic species is truly variable. The radula presented no perceptible differences between forms. The real status of A. multispiralis remains somewhat dubious. Wiese (2001) illustrated the holotype of Danilacarina elenae from Kerguelen Is. and corroborated the synonymy of A. multispiralis .
