in south westem Norway.
General depth range: From 246 to 400 m (Monniot and
Klitgaard, 1994).
Remarks: Molgula mira is like M. herdmani a rare species
apparently with a somewhat similar distribution area.
The bathymctric rangc (246-400 m) indicates that this
is a slope species.
It is notable, that all records of M. mira are associ-
atcd wilh sponge records.
The phylogeny of this species is of interest, as it like
Eugyra arenosa, has only one gonad, but like all other
Molgula species the branchial sac has folds. M. mira
is urodele and the branchial sac has, iike several other
molgulids, six folds on each sidc.
