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
.
